Sudan

Sudan is a country in northeastern Africa with a total area of about 1.86 million square kilometres, bordered by Egypt, Libya, Chad, the Central African Republic, South Sudan, Ethiopia and the Red Sea. Its geography is dominated by the Nile system, whose Blue Nile and White Nile branches meet at Khartoum, and by desert in the north. Its position between the Arab world of North Africa and the savanna belt of sub-Saharan Africa has shaped its languages, religion, trade routes and politics. Sudan has also been the site of major civilizations, including the Kingdom of Kush, whose pyramids and royal cities at Meroë and Napata are among the country's best-known heritage sites.

The modern state has been marked by repeated armed conflict, a 2011 secession that created South Sudan, and a political transition that was interrupted by a 2021 military takeover. Since April 2023, a war between the Sudanese Armed Forces and the Rapid Support Forces has caused mass displacement and a severe humanitarian crisis, and it has deeply affected the country's economy, health system and institutions. Understanding Sudan therefore requires attention to its physical geography and climate, its long history from antiquity to independence, its ethnic and religious diversity, its natural resources and economy, and the environmental pressures, especially on water supply and land, that bear on its future.

This entry first describes Sudan's territory, rivers and climate, then traces its history from ancient Nubia through the Mahdist state, the Anglo-Egyptian condominium, independence and the civil wars. It then examines the government, population, economy, infrastructure, education and health, the humanitarian situation, cultural heritage, environmental challenges, foreign relations, and the main gaps in current research.

Name, Location and Borders

The official name is the Republic of the Sudan, in Arabic Jumhūriyyat as-Sūdān. The name derives from bilād as-sūdān, conventionally translated as “land of the Black peoples,” a historical Arabic geographical expression for a much broader belt south of the Sahara, rather than the territory of the modern state alone. Sudan lies in northeastern Africa, with Khartoum, its capital, at the junction of the Blue Nile and White Nile. Its area is commonly reported as 1,886,068 square kilometres, making it Africa’s third-largest country after Algeria and the Democratic Republic of the Congo. (sudanembassy.nl)

Sudan has seven land neighbours: Egypt to the north, Libya to the northwest, Chad to the west, the Central African Republic to the southwest, South Sudan to the south, Ethiopia to the southeast, and Eritrea to the east. Its northeastern frontage is on the Red Sea, with a coastline approximately 850 kilometres long, commonly measured at 853 kilometres. This coast provides access to maritime routes between the Mediterranean, through the Suez Canal, and the Indian Ocean. Port Sudan is the principal maritime gateway; the coast also contains the export terminals connected by pipelines to oil-producing areas inland, including those in landlocked South Sudan. (emro.who.int)

South Sudan’s independence on 9 July 2011 fundamentally changed Sudan’s geographical scale. The former united country covered approximately 2.5 million square kilometres and was Africa’s largest state; separation removed roughly one-quarter of that territory and left Algeria as the continent’s largest country. It also placed a substantial population outside Sudan’s borders: the 2008 census had counted 8.26 million inhabitants in the southern territory. These are historical census figures, not a measure of the population on independence day. Sudan ceased to border Uganda, Kenya and the Democratic Republic of the Congo, while acquiring a long international boundary with South Sudan. The alignment and demarcation of that boundary, and the final status of Abyei, remained matters for negotiation. (un.org)

The partition also divided the resource base and infrastructure of the former state. The World Bank estimates that Sudan lost about three-quarters of its oil reserves with secession; an International Monetary Fund assessment recorded a loss of approximately 75 percent of oil output. Much of the producing territory became South Sudanese, whereas the established export pipelines and Red Sea outlets remained in Sudan. Separation therefore created two sovereign states without separating the physical production-and-export network: southern crude continued to require transport across Sudan to reach overseas markets. (documents1.worldbank.org)

Sudan’s principal geographical regions are broader than its administrative divisions. The northern desert includes the Nubian Desert east of the Nile and desert country to its west, with settlement concentrated along the river. The central clay plains include Gezira, between the Blue and White Niles, and extend southward and eastward into major agricultural districts. Kordofan occupies the west-central interior between the Nile country and Darfur, combining sandy plains in the north with the Nuba Mountains farther south. Darfur forms the western region adjoining Chad and the Central African Republic, with plains and plateaus surrounding the Marra Mountains. In the northeast, the Red Sea Hills separate the interior from a narrow coastal plain, generally about 16–40 kilometres wide. These regions distinguish the Nile-centred heartland, western interior and maritime east without implying uniform terrain within any of them. (en.wikisource.org)

Relief and Drainage

Sudan’s dominant landforms are broad plains and plateaus, crossed in the east-central part of the country by the generally north-flowing Nile and its tributaries. The plains are interrupted by the Darfur highlands in the west and bounded by the Ethiopian Plateau and Red Sea Hills in the east. Northern Sudan consists largely of sand- and gravel-covered desert, with flat-topped sandstone mesas and isolated granite hills. Farther south, extensive clay plains contrast with the undulating sandy country, commonly called qoz, of western Sudan. This predominantly low-relief landscape is not uniformly flat: resistant rock outcrops, volcanic massifs and dissected plateaus produce substantial local differences in elevation. (sd.chm-cbd.net)

At Khartoum, the Blue Nile, arriving from the Ethiopian Highlands, joins the White Nile, whose headwaters extend into the equatorial Great Lakes region, to form the main Nile. Their waters can be visibly distinguished at the confluence by their contrasting sediment loads: the White Nile carries light-grey suspended material, while the Blue Nile carries darker sediment eroded from its upland catchment. A natural-colour satellite image acquired on April 26, 2013, documented the meeting of the two rivers near the end of the dry season, when the Blue Nile was comparatively narrow. Below Khartoum, the Nile flows northward, but its course through northern Sudan includes the Great Bend, where it turns southwest before resuming its journey toward Egypt. Bedrock constrictions and cataracts interrupt this desert reach. (science.nasa.gov)

The principal western highland is the volcanic Marra Mountains of Darfur. Jebel Marra reaches approximately 3,042 metres, making it Sudan’s highest elevation. Its volcanic field includes basaltic lava flows, thick pyroclastic deposits and the steep-walled Deriba caldera, approximately 5 kilometres across. The Smithsonian Institution’s Global Volcanism Program describes the caldera as having formed about 3,500 years ago during an eruption whose pyroclastic flows travelled more than 30 kilometres. The Red Sea Hills form the eastern upland margin of the plains. In south-central Sudan, the Nuba Mountains consist of groups of isolated hills, or inselbergs, rising abruptly from the surrounding clay plain rather than forming a continuous mountain barrier. (volcano.si.edu)

The Atbara, draining the Ethiopian and Eritrean highlands, joins the main Nile downstream of Khartoum; the Dinder and Rahad enter the Blue Nile within Sudan. Their hydrological regimes differ sharply from that of the White Nile. Equatorial lakes and the Sudd wetlands in South Sudan moderate the White Nile’s seasonal fluctuations, whereas summer rainfall over the Ethiopian Highlands produces a concentrated flood pulse in the Blue Nile and Atbara. Approximately 85 percent of the Blue Nile’s annual flow occurs between July and October. The Dinder, Rahad and Atbara system are more strongly seasonal, with very low flows or dry reaches during much of the remaining year. Thus, flood conditions in Sudan depend heavily on rainfall far upstream, not simply on precipitation beside the river. (sciencedirect.com)

Outside the perennial river corridors, seasonal channels provide locally important drainage and agricultural water. In eastern Sudan, the Gash near Kassala and the Baraka feeding the Tokar delta carry short-lived floods that are diverted onto fields through spate irrigation. The timing and extent of inundation determine how much land can be planted and how much moisture remains available to crops. In 1997, for example, strong Gash floods allowed 34,000 hectares of the Gash Die area to be planted with sorghum after producing nothing the previous year, while poor flooding limited cultivation at Tokar. Western Sudan likewise depends extensively on wadis and seasonal water sources that may dry up between rains. (fao.org)

Climate and Vegetation

Sudan’s climate grades from hyper-arid desert in the north through semi-arid steppe to tropical, summer-rain savanna along its southern borders. Rainfall generally increases southward: ecological classifications distinguish desert receiving approximately 0–75 mm annually, semi-desert receiving 75–300 mm, and woodland savanna above roughly 300 mm. Southern Darfur, South Kordofan and Blue Nile contain much of the wetter vegetation within the present country. The seasonal northward movement of the Intertropical Convergence Zone, where tropical airflows meet, brings moist air and summer rain; its retreat restores predominantly dry conditions. Elevation and soils modify this broad latitudinal pattern, particularly in the Marra Mountains, Nuba Mountains and Red Sea Hills. (fao.org)

Temperatures remain high across the lowlands, with mean annual values commonly between 26°C and 32°C, but northern Sudan has a pronounced winter–summer contrast. The Japan Meteorological Agency’s published monthly normals for Wadi Halfa show mean temperatures of 17.5°C in January, 34.7°C in July and 35.3°C in August. These are monthly means, not daytime maxima: summer temperatures in the far north frequently exceed 43°C. Farther south, rainy-season cloud and moisture interrupt the hottest conditions. Historical Sudan Meteorological Department tables illustrate the contrast in northern desert temperatures: Wadi Halfa’s mean daily maximum was 24.6°C in January and 41.1°C in July, while corresponding mean daily minima were 8.7°C and 24.5°C. Mountain areas form cooler local environments within this predominantly hot country. (preventionweb.net)

Most rain in the southern agricultural belt falls between approximately June and October, with a shorter season farther north. Rainfall is highly variable between years and within individual seasons; delayed onset or prolonged dry intervals can reduce plant growth even when the seasonal total is not exceptionally low. Historical drying is measurable but should not be treated as a uniform, uninterrupted decline everywhere. A 2011 analysis by Chris Funk and colleagues at the United States Geological Survey found that summer rains in western Sudan and the then-unified country’s southern regions had declined by 10–20% since the mid-1970s. Its Darfur series showed average rainfall in 1990–2009 approximately 20% below the 1900–1989 average. More recent climate assessments retain substantial uncertainty about future rainfall changes, including possible increases in some western and southeastern areas; warming nevertheless increases evaporative losses. (pubs.usgs.gov)

Vegetation reflects both rainfall and access to locally concentrated water. Northern desert is largely bare, with woody plants concentrated along the Nile and seasonal watercourses. Southward, desert scrub and semi-desert support scattered thorn trees and predominantly annual grasses. Acacias dominate many communities, but soil differences produce distinct associations: Acacia mellifera is characteristic of clay areas, whereas sandy areas support mixtures including Acacia tortilis, Commiphora africana and, in wetter locations, Acacia senegal, the gum-arabic tree. Woodland savanna becomes more extensive toward southern Darfur and Kordofan, with baobabs and broadleaved trees such as Combretum, Terminalia and Anogeissus. These are ecological transitions rather than sharply bounded belts; soil texture and seasonal inundation can alter vegetation within the same rainfall zone. (fao.org)

Wetter grasslands, riverine woodland and seasonal wetlands provide habitats distinct from surrounding dry savanna. In southeastern Sudan, Dinder National Park contains mayas, seasonally flooded depressions and former river channels whose inundation sustains wet meadows and dry-season water sources. Such patches concentrate wildlife when surrounding grasslands dry out. The extensive permanent swamps traditionally described as occupying Sudan’s “far south,” especially the Sudd, are now in South Sudan, not within Sudan’s post-2011 boundaries. Within present-day Sudan, the ecological contrast is principally between sparse northern vegetation, seasonally productive savanna and localized river-fed or flood-fed habitats. (d-nb.info)

Ancient Nubia and the Kingdom of Kush

Neolithic communities along the Nile developed well before the emergence of Nubian states. In the Kerma region, the cemetery at El-Barga dates to approximately 6000–5500 BCE, while cemeteries at Kadruka document communities of the fifth millennium BCE. Pastoral villages, followed by the pre-Kerma settlements of approximately 3200–2500 BCE, reveal increasing settlement concentration before and during the early dynastic period in ancient Egypt. The kingdom centred on Kerma, south of the Third Cataract, flourished approximately 2500–1500 BCE. Its inhabitants combined livestock keeping, cultivation, hunting and fishing with commerce in gold, ivory, ebony and animal hides. Monumental mud-brick temples known as deffufas, together with large royal burial mounds, distinguish Kerma’s urban and ceremonial landscape. Its location connected the Nile valley with desert routes towards the Red Sea and Africa’s interior. Egyptian conquest in the fifteenth century BCE ended its independence and introduced several centuries of Egyptian administration in much of Nubia. (kerma.ch)

A renewed Kingdom of Kush emerged during the early first millennium BCE, with Napata, near the Fourth Cataract, as a principal royal and religious centre. The nearby mountain of Gebel Barkal was associated with Amun, whose worship helped legitimate Kushite kingship. In the eighth century BCE, Kushite rulers extended their authority northwards: Piye campaigned in Egypt, and his successors consolidated the Twenty-fifth Dynasty. Taharqa, who reigned approximately 690–664 BCE, sponsored major building programmes in Egypt and Nubia. Assyrian invasions broke Kushite control of Egypt during the seventh century BCE, although Tanutamani briefly attempted to restore it. The dynasty’s loss of Egypt did not terminate Kushite sovereignty in Nubia. (metmuseum.org)

Meroë, between the Fifth and Sixth Cataracts, gradually became the kingdom’s political centre; the establishment of its principal royal cemetery around the third century BCE marks an important stage in this transition. Napata nevertheless retained religious significance. Meroë’s position at the intersection of caravan routes and Nile communications supported long-distance trade, while the wetter southern hinterland sustained agriculture and livestock. Kushite workshops produced textiles, decorated pottery, jewellery and metal objects; imported wine, glass and metal vessels demonstrate connections with Egypt and the Mediterranean. Excavated furnaces, bellows components and extensive slag heaps establish Meroë as a substantial iron-production centre. Charcoal-fuelled smelting and subsequent forging supplied tools and weapons, but the evidence does not establish iron exports as the kingdom’s dominant source of wealth. (metmuseum.org)

Relations with Roman Egypt included both conflict and negotiation. In 24 BCE, Kushite forces attacked settlements in southern Egypt and carried off imperial statues. Roman retaliation under the prefect Petronius reached and sacked Napata. Queen Amanirenas and Prince Akinidad appear on a monumental inscription from Hamadab associated with this historical setting. Negotiations culminated in the Treaty of Samos in 20 BCE, which established a frontier arrangement while preserving Kushite independence. These northern connections complemented older routes towards the Red Sea and the African interior rather than replacing them. (britishmuseum.org)

By the second century BCE, the Meroitic script was used to write the kingdom’s indigenous language, supplementing the Egyptian writing previously employed at court and in temples. Its 23 signs appeared in two forms: a hieroglyphic version used chiefly on monuments and a more widely employed cursive version. Their sound values are understood, but substantial parts of Meroitic vocabulary and grammar remain unresolved; reading an inscription’s sounds therefore does not necessarily yield its meaning. The 42-line Hamadab inscription illustrates this limitation: names and parts of its historical context can be identified, but a complete translation remains unavailable. (ucl.ac.uk)

Royal cemeteries at el-Kurru, Nuri, Gebel Barkal and Meroë preserve distinctive steep-sided pyramids, burial chambers and funerary chapels. Kushite rulers who governed Egypt were buried in their Nubian homeland; Taharqa’s tomb at Nuri is a prominent example. Jewellery, offering tables, amulets and funerary figurines show the resources devoted to royal burial and the adoption of Egyptian-derived afterlife traditions. These practices coexisted with locally distinctive religious forms. Alongside Amun and Isis, Meroitic temples honoured the lion-headed god Apedemak, notably at Naqa and Musawwarat es-Sufra. The monuments thus document a kingship that combined Egyptian religious imagery with Nubian institutions and deities, rather than simply reproducing Egyptian models. (whc.unesco.org)

Christian Kingdoms, Islamization and Early Modern Period

By the sixth century, three kingdoms occupied the Sudanese Nile valley: Nobatia, with its capital at Faras; Makuria, centred on Old Dongola; and Alodia, or Alwa, whose capital, Soba, stood on the Blue Nile near present-day Khartoum. Their adoption of Christianity connected them to Byzantine diplomacy and the churches of Egypt. The missionary Julian converted Nobatia’s ruler around 543, while Longinus brought Christianity to Alodia in 580. Makuria also became Christian during the sixth century. Churches, monasteries and episcopal institutions subsequently became important components of royal government, while Greek, Coptic and Old Nubian were used in religious and written culture. (nowa.muzarp.poznan.pl)

The Arab conquest of Egypt did not immediately bring Nubia under Muslim rule. After an unsuccessful siege of Dongola in 651–652, Makuria and Egypt’s Muslim authorities concluded the baqt, an agreement regulating peaceful relations, travel and exchanges of goods and enslaved people. It provided a framework for diplomacy over subsequent centuries, although observance varied and military confrontations continued. Nobatia was absorbed into Makuria by about 700, but Alodia remained a separate kingdom. From the thirteenth century, Egyptian intervention and conflicts over the Makurian succession weakened royal authority; the survival of Christian communities therefore extended beyond the decline of their principal political institutions. (academic.oup.com)

The spread of Islam and Arabic was a prolonged process rather than the result of a single conquest. Muslim merchants established communities within Christian territories, while migration from Egypt, intermarriage and pastoral movement gradually altered settlement and language patterns. Sufi teachers reinforced this process through religious instruction and locally established communities. Around the beginning of the sixteenth century, Alodia disappeared as a kingdom; accounts differ over the respective roles of Arab forces associated with Abdallah Jamma and the Funj. In 1504, Amara Dunqas established the Funj Sultanate at Sennar. By the traveller David Reubeni’s visit in 1523, its ruler was recorded as Muslim. The state united tributary rulers rather than administering all its territory directly: dependent chiefs supplied taxes, tribute and troops to the sultan, or mek. (etheses.dur.ac.uk)

In Darfur, the ruling house was the Keira dynasty, rather than a dynasty conventionally named Musa; Musa was one of its early rulers. Traditionally associated with Sulayman Solong, the dynasty developed a Muslim sultanate during the seventeenth century, although the chronology of its earliest rulers remains disputed. Later rulers strengthened Islamic institutions by supporting teachers and mosques. During the eighteenth century, they consolidated their authority, established a capital at El Fasher and competed with Sennar for Kordofan. Enslaved people served in households, armies and administration, as well as being exported; rulers collected duties on this commerce and benefited from raids into territories south of Darfur. (en.wikipedia.org)

These states participated in overlapping trade networks linking the Nile, the Red Sea and the Sahel. The Darb al-Arbaʿin, or “Forty Days’ Road”, connected Darfur with Asyut in Upper Egypt through desert routes and oases. Connections westward reached Wadai and Bornu, while eastern routes linked Nile markets and Sennar to Suakin and maritime commerce with Arabia. Enslaved people, ivory, ostrich feathers and livestock were exchanged for textiles and other Egyptian, Syrian and European manufactures. Caravan traffic also supported the movement of pilgrims and religious scholars, connecting commercial exchange with the spread of Islamic learning. (academic.oup.com)

Muhammad Ali, Egypt’s governor under the Ottoman Empire, launched an invasion in 1820, seeking territorial control and enslaved recruits for his army. Egyptian forces conquered Kordofan and accepted the surrender of Sennar’s last Funj sultan, Badi IV, in 1821. The resulting regime, known as the Turkiyya, imposed heavy taxation and organized provinces, garrisons and subordinate administrative districts; Khartoum became the governor-general’s seat in 1835. Local chiefs were incorporated as intermediaries and tax collectors. State demands for soldiers and commercial profits intensified slave raiding, subsequently extending farther south. Darfur initially remained outside this administration and was annexed only in 1874. (countrystudies.us)

Mahdist State and Anglo-Egyptian Condominium

In 1881 Muhammad Ahmad, a Sudanese religious teacher, proclaimed himself the Mahdi, the divinely guided redeemer expected in Islam, and began an uprising against Turco-Egyptian rule. His followers, known as the Ansar, drew support from communities opposing taxation and foreign administration, religious networks, and merchants whose interests had been affected by attempts to suppress the slave trade. Britain’s occupation of Egypt in 1882 subsequently brought British power directly into the conflict. Mahdist victories in Kordofan undermined Egyptian control, and on 26 January 1885 the Ansar captured Khartoum, killing its British governor-general, Charles Gordon, before a relief expedition arrived. The conquest established the Mahdist State as the dominant power across much of Sudan. (en.wikipedia.org)

Muhammad Ahmad died in 1885, leaving his successor, Abdallahi ibn Muhammad, known as the Khalifa, to consolidate the state from Omdurman. The Khalifa appointed provincial governors drawn from the Ansar and combined military command with religious authority. Courts enforced Islamic law and the Mahdi’s precepts; workshops manufactured ammunition and maintained river steamers. Control was strongest in the northern and central regions and did not encompass the whole of the south. External campaigns placed further demands on the state: an invasion of Egypt ended in defeat at Tushki in 1889. In March 1896 Herbert Kitchener began an Anglo-Egyptian campaign supported by Nile gunboats and a railway built to move troops and supplies across northern Sudan. On 2 September 1898 his army defeated the Khalifa’s forces outside Omdurman and occupied the capital. The National Army Museum gives approximately 10,000 Mahdist dead, against 48 dead in Kitchener’s force, illustrating the disparity created by modern rifles, Maxim machine guns and artillery. The Khalifa escaped but was killed at Umm Diwaykarat in November 1899. (countrystudies.us)

The agreement signed on 19 January 1899 established the Anglo-Egyptian Condominium, formally a joint British-Egyptian administration. Its institutional arrangements nevertheless ensured British predominance: the governor-general was appointed by the Egyptian khedive on Britain’s recommendation and could be removed only with British consent. He possessed extensive military, executive and legislative powers. British officials occupied the principal provincial posts, Egyptians initially filled intermediate positions, and Sudanese increasingly entered subordinate government employment. Administration operated through provinces and districts rather than two constitutionally separate northern and southern states. From the 1920s, indirect rule delegated local judicial and administrative functions to recognized chiefs and shaykhs under British district commissioners. Darfur, where Sultan Ali Dinar had re-established his rule after the Mahdist collapse, was annexed in 1916. (en.wikisource.org)

Colonial investment concentrated on the Nile valley and export production. The government and the Sudan Plantations Syndicate began developing the Gezira Scheme in 1911 to supply cotton to Britain’s textile industry. Completion of the Sennar Dam in 1925 enabled a much larger area between the Blue and White Nile to receive irrigation. Water flowed through canals to tenant farms, exploiting the plain’s gentle slope, while cotton travelled by railway to Port Sudan for export. The scheme linked agricultural production, hydraulic infrastructure and overseas markets, making cotton central to the colonial economy. The Sudan Gezira Board replaced private management in 1950. (countrystudies.us)

Separate administration became especially pronounced in the southern provinces of Equatoria, Bahr al-Ghazal and Upper Nile. Restrictions on northern Sudanese entering or working in the south, the replacement of Arabic-speaking officials, and support for missionary schools reduced northern commercial and cultural influence. English and local languages were promoted instead of Arabic, while some southern students pursued further education in British East Africa rather than Khartoum. A 1930 directive formalized the treatment of the south as culturally distinct and envisaged closer association with East Africa. The government reversed this separation policy in 1946, moving toward a unified administration; a partially elected Legislative Assembly representing both regions followed in 1948. The Anglo-Egyptian agreement of 12 February 1953 provided for self-government and self-determination, initiating the final transition from condominium rule to independence on 1 January 1956. (countrystudies.us)

Independence and Early Political History

Sudan became independent on 1 January 1956, following parliament’s unanimous declaration of independence on 19 December 1955. Prime Minister Ismail al-Azhari, whose National Unionist Party had previously supported union with Egypt, instead led the country toward separate statehood. The provisional constitution established parliamentary government, with a five-member commission serving collectively as head of state and executive authority exercised by the prime minister. No agreement had been reached on a permanent constitution or on southern demands for regional autonomy. During 1956, Azhari’s government was replaced by an Umma–People’s Democratic Party coalition headed by Abdallah Khalil. Disputes over constitutional arrangements, relations with Egypt and foreign assistance weakened the coalition, while falling cotton earnings placed pressure on foreign-exchange reserves. (countrystudies.us)

On 17 November 1958, General Ibrahim Abboud took power in a military coup arranged with Khalil’s involvement. Political authority passed to a Supreme Council of the Armed Forces, ending the first period of parliamentary rule. Abboud’s government pursued Arabization in the south and expelled foreign missionaries in February 1964, while the southern insurgency continued. Popular opposition culminated in the October Revolution of 1964: demonstrations and strikes forced the military to relinquish government. Civilian parliamentary rule returned, but successive governments between 1964 and 1969 failed to settle the constitutional question or end the southern conflict. (countrystudies.us)

Colonel Jaafar Nimeiri and the Free Officers’ Movement seized power on 25 May 1969. Their ten-member Revolutionary Command Council suspended the provisional constitution, abolished existing government institutions and banned political parties. The new regime initially adopted a socialist programme and nationalized banks and businesses. Its cooperation with communist politicians subsequently broke down. On 19 July 1971, officers led by Major Hashim al-Atta briefly displaced Nimeiri; loyal forces restored him three days later. Executions and arrests followed. Nimeiri became president later in 1971, and the Sudan Socialist Union became the regime’s authorized political organization. (countrystudies.us)

The Addis Ababa Agreement of 1972 ended the first southern civil war, which had begun in 1955. Negotiations brought together Nimeiri’s government and the Southern Sudan Liberation Movement led by Joseph Lagu, with assistance from Emperor Haile Selassie of Ethiopia. The settlement combined Equatoria, Bahr al-Ghazal and Upper Nile into one autonomous Southern Region, administered through a regional assembly and High Executive Council, with Juba as its capital. Defence, foreign affairs and currency remained national responsibilities. English became the south’s principal administrative language. Security provisions envisaged a 12,000-member Southern Command, divided equally between personnel from the region and from elsewhere in Sudan, providing a framework for integrating former Anyanya guerrillas. (countrystudies.us)

The agreement provided approximately eleven years without full-scale north–south war, but its political safeguards were progressively weakened. Nimeiri’s 1977 “national reconciliation” admitted former opponents, including Muslim Brotherhood supporters, into political life within the existing regime. On 5 June 1983, he divided the autonomous Southern Region into three regions, dismantling the unified arrangement established in 1972. Southern army mutinies had already occurred in May, before the subsequent religious legislation. These developments accompanied the emergence of the Sudan People’s Liberation Movement and its armed wing and the renewal of civil war. (2009-2017.state.gov)

In September 1983, Nimeiri introduced the “September Laws,” making Islamic law central to the legal system and incorporating punishments including flogging and amputation into criminal law. The measures alienated non-Muslim southerners and also encountered opposition among Muslims. Economic deterioration and rising food, fuel and transport prices contributed to demonstrations and a general strike in 1985. In April, military officers removed Nimeiri while he was abroad. A transitional military government subsequently organized elections and transferred power to civilians in 1986; although implementation of certain Islamic punishments was suspended, the September Laws were not fully repealed. (hrw.org)

Civil Wars, Darfur and Secession of South Sudan

The second Sudanese civil war began in 1983 after the breakdown of the 1972 Addis Ababa settlement. President Jaafar Nimeiri dismantled southern autonomy, while disputes over political representation and control of southern oil resources deepened opposition to Khartoum. Mutinies by southern soldiers, notably at Bor in May 1983, preceded the nationwide introduction of Islamic law that September. John Garang organized the Sudan People’s Liberation Movement and its military wing, the SPLM/A, initially advocating a united, secular Sudan rather than southern independence alone. Fighting extended beyond the south into the Nuba Mountains and Blue Nile, making the conflict more than a simple confrontation between two territorially distinct regions. (hrw.org)

Negotiations under the Intergovernmental Authority on Development produced the Comprehensive Peace Agreement (CPA), signed in Nairobi on 9 January 2005 by the Sudanese government and SPLM/A. It established a six-year interim period, an autonomous southern government, national power-sharing arrangements and a referendum on southern self-determination. Security provisions allowed the principal northern and southern armies to remain separate while creating joint integrated units. For oil produced in southern Sudan, 2 per cent of revenue was allocated to producing states or regions; the remaining net revenue was divided equally between the southern government and the Government of National Unity. Separate protocols addressed Abyei, Southern Kordofan and Blue Nile, but the agreement did not settle the concurrent Darfur conflict. (digitallibrary.un.org)

In Darfur, attacks on government targets by the Sudan Liberation Movement/Army and Justice and Equality Movement in February 2003 were followed by government military operations and the mobilization of local militias, including the Janjaweed. In July 2004, the UN Security Council demanded that Sudan disarm these militias and bring perpetrators of atrocities to justice. The UN’s international commission of inquiry subsequently documented serious violations by government forces and militias, and also found evidence of rebel violations that might constitute war crimes. A UN briefing in October 2019 cited estimates of approximately 300,000 conflict-related deaths and 2.7 million people driven from their homes; these were estimates rather than a comprehensive casualty count. Security Council Resolution 1593 referred the Darfur situation to the International Criminal Court on 31 March 2005. The Court issued arrest warrants for President Omar al-Bashir on 4 March 2009 for alleged war crimes and crimes against humanity, and on 12 July 2010 for alleged genocide; warrants were not convictions. (peacekeeping.un.org)

The southern referendum held in January 2011 returned 98.83 per cent support for independence, and South Sudan became independent on 9 July 2011. Abyei’s separately envisaged referendum did not take place, leaving its status unresolved; renewed violence there displaced more than 100,000 people before the Security Council established the UN Interim Security Force for Abyei in June 2011. Secession also left an economically consequential separation between southern oilfields and export pipelines crossing Sudan. Disagreement over transit fees prompted South Sudan to announce a production shutdown on 20 January 2012. African Union mediation helped secure nine agreements on 27 September 2012 covering oil, security, borders, trade and other bilateral matters, but these did not resolve every territorial dispute or Abyei’s final status. (un.org)

Darfur peace initiatives repeatedly encountered incomplete participation and implementation. The 2006 Darfur Peace Agreement left important movements outside the settlement. The Doha Document, signed on 14 July 2011 by the government and Liberation and Justice Movement, likewise excluded major rebel factions. The Juba Peace Agreement of 3 October 2020 covered Darfur and other conflict-affected regions, providing for power-sharing, reconstruction and security arrangements, but Abdel Wahid al-Nur’s Sudan Liberation Movement and Abdelaziz al-Hilu’s SPLM–North remained outside it. In 2021, UN reporting described implementation as slow and intercommunal violence as persistent. A January 2022 UN expert report identified a gap between promised funding and available support, while the UN and African Union called in May 2022 for implementation of security arrangements without further delay. (digitallibrary.un.org)

Revolution, Transition and the 2021 Takeover

Protests against bread-price increases and shortages spread across Sudan in December 2018, with major demonstrations in Atbara on 19 December. Economic grievances developed into demands for the removal of President Omar al-Bashir, who had held power since 1989. The Sudanese Professionals Association, opposition parties and neighbourhood resistance committees organized demonstrations, strikes and civil disobedience. On 6 April 2019, protesters established a sit-in outside the armed forces headquarters in Khartoum. The military removed and detained Bashir on 11 April, ending nearly thirty years of his rule, but installed a Transitional Military Council rather than immediately transferring authority to civilians. Protesters consequently maintained the sit-in and demanded civilian government. (sudan.un.org)

The confrontation intensified on 3 June 2019, when security forces violently dispersed the Khartoum sit-in. Human Rights Watch subsequently documented killings, sexual violence and other abuses, identifying the Rapid Support Forces (RSF) as leading the operation alongside other security forces. The crackdown interrupted negotiations and prompted further strikes and demonstrations. Mediation involving the African Union and Ethiopia helped produce a July political agreement and an August Constitutional Declaration, formally signed on 17 August. These agreements established a negotiated military–civilian transition rather than the exclusively civilian administration sought by many demonstrators. (hrw.org)

The Constitutional Declaration envisaged a 39-month transition culminating in elections. Its eleven-member Sovereignty Council comprised five military representatives, five civilians selected by the Forces of Freedom and Change (FFC), and one civilian chosen jointly. The chairmanship was allocated to the military for the first 21 months and to civilians for the remaining eighteen. General Abdel Fattah al-Burhan became council chairman, while economist Abdalla Hamdok took office as prime minister on 21 August 2019. The FFC nominated the prime minister and most cabinet ministers, but the military members selected the defence and interior ministers. A transitional legislative council, intended to provide lawmaking and oversight, was never established before the takeover. The arrangements therefore divided authority without placing the armed institutions fully under civilian control. (constituteproject.org)

On 25 October 2021, Burhan led a military takeover: Hamdok and other civilian officials were detained, the cabinet and Sovereignty Council were dissolved, a state of emergency was declared, and key provisions of the transitional constitutional framework were suspended. The UN Security Council called for restoration of the civilian-led transitional government. The takeover also interrupted economic reintegration: the World Bank paused all disbursements on 25 October and stopped processing new operations, while international assistance and the debt-relief process were disrupted. Renewed demonstrations encountered lethal repression; by December 2022, Sudanese medics had recorded more than 100 civilian deaths during anti-takeover protests. (sudan.un.org)

A political agreement between Burhan and Hamdok on 21 November 2021 reinstated the prime minister but did not restore the previous military–civilian partnership. Major civilian groups rejected the arrangement, and protests continued. Hamdok resigned on 2 January 2022 amid the political deadlock. Subsequent mediation by the UN Integrated Transition Assistance Mission in Sudan, the African Union and the Intergovernmental Authority on Development—the “Trilateral Mechanism”—supported negotiations that produced a Political Framework Agreement on 5 December 2022. Military leaders and participating civilian parties envisaged a new, two-year civilian-led transition, but deferred transitional justice, security-sector reform and other contentious questions to further negotiations. (minio.uninfo.org)

The framework lacked broad acceptance: resistance committees opposed renewed partnership with military leaders, while several political parties and former rebel movements remained outside it. Negotiations in early 2023 addressed dismantling Bashir-era structures, the Juba Peace Agreement, eastern Sudan, transitional justice and security reform. The latter exposed unresolved disputes between the armed forces and the RSF over integration timetables and the chain of command. A final agreement and new civilian government were not established before fighting began between the two forces on 15 April 2023. (unitams.unmissions.org)

War Since 2023

Fighting broke out on 15 April 2023 between the Sudanese Armed Forces (SAF), commanded by Abdel Fattah al-Burhan, and the Rapid Support Forces (RSF), led by Mohamed Hamdan Dagalo, commonly known as Hemedti. The confrontation followed disagreements over security-sector reform, particularly the integration of the RSF into the regular army and the military’s position under a proposed civilian government. Battles engulfed Khartoum and spread to Darfur and other regions. Air bombardment, artillery fire and fighting in populated neighbourhoods damaged civilian facilities from the opening days: by 24 April, the United Nations humanitarian coordination office had reported at least 427 deaths, more than 3,700 injuries and attacks on 11 health facilities. These were preliminary figures, not a comprehensive civilian death toll. (sudan.un.org)

The military balance changed substantially during 2024–2025. An SAF offensive beginning in September 2024 recovered territory in central Sudan; its forces retook Wad Madani in January 2025 and Khartoum in March. This did not end the war: major fighting increasingly centred on Darfur and Kordofan. El Fasher, the capital of North Darfur, remained defended by the SAF and allied armed movements while the RSF controlled the other Darfur state capitals. After approximately 18 months of siege, the RSF announced its capture of El Fasher, including the army’s 6th Infantry Division headquarters, on 26 October 2025. The UN Human Rights Office subsequently documented mass killings during the final offensive and along routes used by people fleeing the city. (securitycouncilreport.org)

El Obeid, the capital of North Kordofan, became another major threatened population centre. On 18 June 2026, UN Secretary-General António Guterres warned that substantial RSF reinforcements around the city could precede a ground offensive. Drone warfare also extended attacks beyond immediate ground fronts. On 3 July, High Commissioner for Human Rights Volker Türk reported that his office had documented 15 drone strikes in El Obeid and surrounding areas between 6 and 28 June, killing at least 45 civilians and injuring 41. Across Kordofan, drones operated by both sides struck markets, schools, fuel stations, water infrastructure and civilian vehicles. The office also documented RSF drone damage to at least 13 fuel stations in El Obeid and Al Rahad, compounding shortages and obstructing transport and essential services. (un.org)

Documented casualties provide minimum counts rather than a reliable measure of total mortality. In its February 2026 report on El Fasher, the UN Human Rights Office recorded more than 6,000 people killed between 25 and 27 October 2025: at least 4,400 inside the city and 1,600 while attempting to escape. It stated that the actual death toll during the week-long offensive was undoubtedly significantly higher. Such incident-based counts also do not encompass all indirect deaths arising from interrupted treatment, hunger and the destruction of water and food systems. The latter mechanisms were documented by the UN’s Independent International Fact-Finding Mission for the Sudan, alongside widespread attacks on infrastructure essential to civilian survival. (storymaps.arcgis.com)

The Fact-Finding Mission’s September 2025 report, Sudan: A War of Atrocities, found that both the SAF and RSF committed war crimes, including attacks on civilians, killings, forced displacement and abuses in detention. It documented reprisals by SAF-aligned forces against Kanabi communities after the recapture of Gezira, as well as executions of suspected RSF collaborators. Its findings concerning the RSF included crimes against humanity such as murder, torture, rape, sexual slavery and persecution. The mission also found that the RSF and allied forces used starvation as a method of warfare around El Fasher; deprivation of essential supplies could additionally amount to extermination. These were findings of an investigative mechanism, distinct from criminal convictions of particular individuals. (documents.un.org)

The International Criminal Court has investigated alleged crimes committed in Darfur during the new war within its existing Darfur investigation, announcing this work in July 2023. Its jurisdiction derives from the UN Security Council referral of 31 March 2005 and covers relevant crimes committed in Darfur from 1 July 2002 onward; it does not automatically encompass every battlefield elsewhere in Sudan. In July 2025, Deputy Prosecutor Nazhat Shameem Khan reported accelerated work on contemporary crimes. The investigation of the current conflict is separate from proceedings concerning the earlier Darfur war, including the October 2025 conviction of Ali Muhammad Ali Abd-Al-Rahman for crimes committed in 2003–2004. (icc-cpi.int)

Government and Constitution

Sudan’s provisional constitution of 1956 adapted the colonial Self-Government Statute of 1953 to independence. It established a parliamentary system in which the cabinet answered to a bicameral parliament, alongside an independent judiciary and protections for fundamental rights. Constitutional government was interrupted by the military takeover of 1958; an amended provisional constitution followed the restoration of civilian government in 1964. Jaafar Nimeiri’s 1973 constitution established a presidential, one-party system, but was replaced by another interim constitution after his overthrow in 1985. The 1989 coup again suspended constitutional government, and Omar al-Bashir’s administration subsequently adopted the 1998 constitution. These successive instruments alternated between parliamentary and presidential arrangements rather than providing a continuously operating constitutional order. (idea.int)

The Interim National Constitution of 2005 incorporated the power-sharing settlement of the Comprehensive Peace Agreement. It provided for a president, two vice-presidents and a national Council of Ministers, with a bicameral legislature comprising the National Assembly and Council of States. Its decentralized structure distinguished national government, the autonomous Government of Southern Sudan, states and local government, and distributed legislative and executive responsibilities between them. A bill of rights and a separate Constitutional Court supplied formal mechanisms for reviewing legislation and government action. Southern Sudan’s independence in 2011 removed the southern institutions from this framework; the remaining national constitutional arrangements continued until the overthrow of Bashir in April 2019. (constituteproject.org)

The Constitutional Declaration signed on 17 August 2019 replaced the presidency with a collective Sovereignty Council and assigned executive administration to a cabinet headed by a prime minister. The original council contained five military members, five civilians nominated by the Forces of Freedom and Change, and one jointly selected civilian. A proposed Transitional Legislative Council was to have no more than 300 members, at least 40 percent of them women, with powers to legislate, approve the budget and withdraw confidence from the cabinet. Pending its formation, legislative powers belonged to joint meetings of the Sovereignty Council and cabinet. This design separated the head-of-state institution from executive administration, while giving both bodies legislative responsibilities during the institutional gap. (constituteproject.org)

The military takeover of 25 October 2021 interrupted those power-sharing arrangements. In February 2025, the military-led authorities amended the declaration, authorizing the Sovereignty Council to appoint and dismiss the prime minister on the recommendation of the transitional legislative authority, composed of the council and cabinet. Abdel Fattah al-Burhan appointed Kamil Idris prime minister on 19 May 2025. Competing institutions also emerged: the Rapid Support Forces and allied groups signed a separate transitional constitution in March 2025 and announced a parallel administration in July, with Mohamed Hamdan Dagalo heading its sovereignty council. These were rival governmental structures, not successive governments exercising uncontested authority throughout Sudan. (spcommreports.ohchr.org)

Sudan’s administrative framework comprises 18 states, subdivided into localities. The 2019 declaration recognized federal, regional or state, and local levels, with exclusive and shared powers to be specified by law; it retained existing arrangements pending a review of territorial boundaries and responsibilities. Governors and state executive administrations connect national institutions with local government. Federalism therefore concerns both territorial administration and the allocation of authority and resources. In the present conflict, Darfur and Kordofan are also areas where armed control and competing administrations limit the reach of national institutions; their administrative boundaries do not themselves establish effective governmental control. (sudan.un.org)

The formal judiciary includes the Supreme Court and subordinate courts, while the 2019 declaration provided for a separate Constitutional Court responsible for constitutional review and protection of rights. Sudan’s legal system also accommodates religious and customary rules. Article 5 of the 2005 constitution designated Islamic sharia and popular consensus as sources of legislation applicable to northern states; the 2019 declaration omitted that formula without automatically replacing existing statutes. Muslim personal-status law continues to regulate matters including marriage and divorce, while customary institutions mediate disputes over land, grazing routes and water access. Statutory reforms have changed particular rules: Law No. 12 of 2020 repealed the criminal provision on apostasy. Customary land rights and statutory tenure remain distinct but overlapping elements of local dispute resolution. (constituteproject.org)

Population, Ethnicity, Language and Religion

Sudan’s last full population census was conducted in April 2008, before South Sudan’s independence in 2011. The United Nations demographic yearbook records 30,504,166 people for the territory now comprising Sudan, separately from the 8,260,490 counted in what became South Sudan. Subsequent totals are estimates rather than new enumerations: the World Bank series gives approximately 50.45 million for 2024 and 51.66 million for 2025, while the United States government estimated 49.2 million in mid-2023. These figures refer to different years and statistical series and are not directly interchangeable. The war beginning in April 2023 has further weakened the evidence available for demographic measurement through mass displacement and interrupted access to communities; the United States Commission on International Religious Freedom noted in 2025 that the absence of comprehensive, credible census data made demographic information imprecise and incomplete. (desapublications.un.org)

Sudan contains hundreds of ethnic communities: the United States Department of State described more than 500 groups in its 2016 country report, while the European Union Agency for Asylum reported approximately 500 in 2025. These are broad descriptions of diversity, not a recent census-based classification. Major regional populations include Nubians along the northern Nile, Beja in the east, Fur, Masalit and Zaghawa in Darfur, and the diverse Nuba communities of South Kordofan. “Nuba” denotes multiple communities sharing a regional homeland and elements of historical experience, rather than a single language group, and is distinct from “Nubian.” Communities identifying as Arab include both riverine populations and pastoral groups in western Sudan. Arab and African identities should not be treated as mutually exclusive biological categories: in Darfur, for example, communities commonly classified as Arab and non-Arab are both predominantly Muslim and have lived in the region for centuries. (2021-2025.state.gov)

The former country’s north–south distinction no longer corresponds to Sudan’s international boundaries. Significant non-Arab populations remain within Sudan, including communities in the Nuba Mountains and Blue Nile region; Christian populations likewise remain in these areas and in northern cities. Consequently, the post-2011 state cannot be described simply as an ethnically Arab or uniformly Muslim “north.” Regional identities overlap with linguistic, religious and local affiliations rather than following a single dividing line. (minorityrights.org)

Arabic and English received explicit status as the national government’s official working languages under Article 8 of the 2005 Interim National Constitution, which also designated them as languages of instruction in higher education. The article recognized all indigenous Sudanese languages as national languages and allowed subnational legislatures to adopt additional official working languages. This provision requires historical qualification: the 2019 Constitutional Charter repealed the 2005 constitution while retaining legislation enacted under it unless subsequently repealed or amended. Sudan’s multilingual population includes speakers of Nobiin and Dongolese in the northern Nile valley, Beja in the east, Fur and Masalit in Darfur, and languages such as Koalib and Nyimang in the Nuba Mountains. A UNESCO-hosted study documented younger Nobiin speakers shifting toward Arabic, illustrating how an indigenous language may persist alongside expanding Arabic use. (moj.gov.sd)

Islam is the majority religion, predominantly in its Sunni traditions. The State Department’s 2023 religious-freedom report cited Pew Research Center estimates for 2020 of 91 percent Muslim, 5.4 percent Christian and 2.8 percent following indigenous religions; these are estimates, not census results. Christian communities include Coptic and other Orthodox churches, Roman Catholics, Anglicans and several Protestant denominations. Their distribution includes Khartoum, Port Sudan and other cities, as well as parts of South Kordofan and Blue Nile. Some Muslims and Christians also incorporate elements of indigenous religious practice. (ecoi.net)

Sufism has an important place within Sudanese Sunni religious and social life. Established orders include the Qadiriyya, introduced in the sixteenth century, and the Khatmiyya, founded in the early nineteenth century by Muhammad Uthman al-Mirghani and historically influential in eastern Sudan. Their organization connects religious leadership with networks of followers and family authority. Religion also intersects with law: the 2019 Constitutional Charter protected religious belief and worship and, unlike the preceding constitutional framework, did not identify sharia as a source of legislation. Nevertheless, existing religion-related laws remained operative pending amendment, and the State Department reported continuing religious distinctions in family-law matters, including child-custody decisions. (uscirf.gov)

Economy, Resources and Trade

Agriculture and livestock underpin Sudan’s rural economy, supplying food, employment and export commodities. Production combines smallholder rain-fed farming, mechanized cultivation and irrigated agriculture, alongside pastoral and agropastoral livestock raising. Sesame, groundnuts, cotton, sheep, camels and gum arabic are important commercial products; much livestock production comes from small-scale herders rather than large enterprises. A 2020 World Bank study identified limited finance, weak processing capacity and difficulties connecting producers to markets as constraints across agricultural value chains. The Bank’s 2025 economic update estimated that agriculture’s share of GDP had risen to approximately 44% in 2024, although this relative increase occurred amid contraction elsewhere in the economy, rather than indicating an agricultural boom. (documents1.worldbank.org)

Agricultural exports connect Sudan to both regional food markets and international industrial supply chains. Gum arabic is collected largely by smallholders, with much exported raw or only partly processed, limiting the value retained domestically. Export earnings reached about US$117 million in 2018; France, India and the United States were important destinations. Sesame is another major export crop, while livestock commerce is oriented particularly toward Saudi Arabia and Egypt. In 2018, Saudi Arabia received 63% of Sudan’s live-animal exports and Egypt 34%. These markets expose producers to changes in animal-health requirements, import restrictions, transport costs and currency values, as well as fluctuations in harvests. (documents1.worldbank.org)

Gold became especially important after the loss of southern oilfields. Artisanal and small-scale mining accounts for most gold extraction and provides livelihoods outside formal wage employment, including for people displaced from farming. Operations range from manual prospecting to mechanically assisted excavation and ore crushing; mercury amalgamation remains a common recovery method. Official figures cited by the Associated Press put production at 70 tonnes in 2025, compared with 64 tonnes in 2024. However, official production and export records do not capture the entire sector: the report also cited a United Nations expert panel’s finding that more than half of Sudan’s gold was smuggled rather than traded through formal channels. This substantial informal economy complicates measurement of export earnings and taxable income. (apnews.com)

South Sudan’s independence in July 2011 removed approximately three-quarters of Sudan’s oil production, half its fiscal revenues and two-thirds of its international payment capacity, according to the International Monetary Fund. The shock simultaneously reduced government income and the foreign currency available to pay for imports, putting pressure on public spending and the Sudanese pound. Oil-transit payments became a separate source of revenue, but disputes over their terms initially compounded the budgetary shortfall. The IMF reported that revenue underperformed by about 30% in the first half of 2012, partly because an agreement on transit fees had not yet been reached. (elibrary.imf.org)

Currency depreciation, monetary financing of fiscal deficits and fuel-price reforms contributed to severe inflation before the current war: annual inflation reached 269% in December 2020, up from 57% a year earlier. On February 21, 2021, the authorities unified most exchange rates at the prevailing market rate of 375 Sudanese pounds per US dollar, excluding the customs valuation rate. International financial restrictions also changed: the United States revoked broad economic sanctions effective October 12, 2017, and rescinded Sudan’s state-sponsor-of-terrorism designation on December 14, 2020. These changes did not remove every restriction; targeted sanctions relating to Darfur and, subsequently, the conflict remained distinct from the former broad embargo. (elibrary.imf.org)

The war beginning in April 2023 sharply reduced production, disrupted trade routes and damaged commercial services. Displacement and looting deprived farms of labour and assets, while shortages of seeds, fertilizer and fuel hindered cultivation and distribution. The World Bank estimated real GDP contractions of 29.4% in 2023 and 14% in 2024, followed by a modest 3.1% rebound in 2025 from an exceptionally low base. Government revenues fell from approximately 10% of GDP in 2022 to below 5% in 2024–2025, restricting the financing of public services even as reconstruction needs increased. (worldbank.org)

Infrastructure, Energy and Transport

Large Nile dams provide the principal hydroelectric generating assets. Merowe, commissioned in 2009 on the main Nile, has an installed capacity of 1,250 megawatts (MW), substantially larger than any other Sudanese power station. Roseires Dam on the Blue Nile was completed in 1966; its power plant has an installed capacity of 280 MW. Heightening works completed in 2013 raised the dam by 10 metres and increased reservoir storage from approximately 3.0 to 7.4 billion cubic metres, improving water regulation for power generation and irrigation. Sediment management is important at Roseires: low-level sluice gates allow sediment-laden floodwater to pass through, limiting the accumulation that would otherwise reduce usable storage. These installations combine hydroelectric generation with river regulation, although installed capacity does not indicate how much electricity can actually be delivered through the electrical grid. (documents1.worldbank.org)

Port Sudan, on the Red Sea, is the main maritime gateway for imports, exports and humanitarian cargo. Its importance depends on inland connections as well as ship-handling facilities: goods must move between the port, warehouses and inland markets through road and railway corridors. A World Bank infrastructure assessment published in 2011 identified long cargo dwell times, high costs and capacity constraints as impediments to port performance. During the war beginning in April 2023, the city became a major humanitarian logistics hub. By May 2024, the Logistics Cluster reported that its Port Sudan facilities had stored more than 25,000 cubic metres of commodities for 22 partner organizations. In 2026, the cluster continued to provide common storage there, including temperature-controlled facilities, alongside inland hubs such as Kassala, Gedaref, Kosti and El Obeid. (documents.worldbank.org)

Railways historically carried bulk commodities over long distances between Port Sudan and central and western Sudan, but deteriorating track, shortages of serviceable locomotives and rolling stock, and competition from trucks reduced their role. The World Bank’s 2015 trade diagnostic recorded that rail carried only about 0.5 million tonnes of approximately 3.8 million tonnes moving along the Port Sudan–Khartoum corridor in 2012. Road construction parallel to railway routes and reduced import duties on trucks had encouraged this shift. Although rail transport was cheaper for container movements in the study, it was slower and less reliable; declining traffic then weakened the railway’s ability to maintain its equipment. These problems predated the current war rather than arising solely from wartime destruction. (documents1.worldbank.org)

Road transport consequently bears most inland freight movement. Sudan’s 2012 Interim Poverty Reduction Strategy estimated a road network of 32,425 kilometres, excluding rural tracks, with about 7,200 kilometres paved; it reported that roads supplied over 90 per cent of inland transport services and that roughly half the paved network needed rehabilitation or resurfacing. Sparse roads leave many rural areas poorly connected, while seasonal streams and flooding can sever existing routes. On 10 September 2024, the Logistics Cluster reported that the El Geneina–Zalingei road was impassable because of rainy-season conditions, several wadis and a collapsed bridge at Monri, illustrating how weather and damaged structures compound wartime access restrictions. (documents1.worldbank.org)

War has impaired energy supply through fuel shortages, loss of staff and damage to generating and distribution facilities. A World Bank assessment for August 2024 reported that only one 125-MW unit at the 500-MW Kosti thermal station was operating because of fuel shortages, while Garri 1 and 2 were shut down for lack of fuel and staff. Isolated diesel systems serving several western towns also experienced repeated fuel interruptions. On 6 May 2025, UN humanitarian coordinator Clementine Nkweta-Salami reported drone attacks targeting Port Sudan’s airport, a fuel-storage facility and a power transformer. The UN subsequently stated that attacks on power stations and other critical infrastructure disrupted access to electricity, healthcare, clean water and food; shortages of fuel also threatened the dispatch of humanitarian supplies inland. (documents1.worldbank.org)

Education and Public Health

Sudan’s education system includes preschool, primary and secondary schooling, technical training, and university education. The school structure historically comprised eight years of basic education followed by three years of secondary education; in 2019, Education Minister Mohamed El Amin announced a reform programme introducing two preschool years, six primary years, and three years each of lower and upper secondary education. Access and attainment were already limited before the war. A World Bank diagnostic report tabulated adult literacy at approximately 60%, primary gross enrolment at 69%, and secondary gross enrolment at 38% for 2018. Gross enrolment measures total enrolment, including over-age and under-age pupils, rather than attendance by the relevant age group alone. Learning outcomes were also weak: UNICEF reported that fewer than half of third-grade pupils in the 2018 National Learning Assessment could comprehend what they read. Rural residence, poverty, displacement and gender inequalities contributed to exclusion and dropout. (en.wikipedia.org)

The war beginning in April 2023 interrupted schooling through insecurity, damaged buildings, displacement and the conversion of schools into shelters. UNICEF estimated that at least seven million children had been out of school before the conflict, rising to 16.5 million in January 2025. Reopening subsequently restored access in some regions: its year-end 2025 report estimated that eight million of seventeen million school-aged children remained out of school. In February 2026, 12,243 of 19,883 schools were operational, or 62%; fewer than one-third were open in North Darfur, South Darfur, West Darfur and West Kordofan. Recovery programmes combined classroom repairs, learning materials and teacher support with accelerated lessons and temporary safe learning spaces. These arrangements provided alternatives where ordinary schools remained inaccessible, but reopening was geographically uneven. (unicef.org)

Higher education includes the University of Khartoum, whose origins lie in Gordon Memorial College, founded in 1902; it acquired university status in 1956. The institution has a longstanding role in professional education, including medicine and engineering. Wartime disruption also affected examination arrangements and medical-training infrastructure. In May 2026, the university reported decentralized examinations conducted for the first time since the outbreak of war and the launch of an international initiative by medical-faculty graduates to support reconstruction and rehabilitation. At school level, UNICEF supported the August 2025 Secondary Education Certificate examination, for which more than 274,000 students registered, helping preserve progression despite interrupted teaching. (uofk.edu)

Sudan’s health system depends on public hospitals and primary-care facilities supported by federal and state health authorities, the National Health Insurance Fund and international partners. War reduced capacity through damage to facilities, the flight of medical personnel, interrupted salaries and shortages of medicines, safe water and electricity. These constraints affected both emergency treatment and routine services, while disrupted surveillance complicated the detection of outbreaks. On 14 April 2026, the World Health Organization (WHO) reported that 37% of health facilities nationwide were non-functional and twenty-one million people lacked health services. International assistance supplied medicines, mobile clinics and operating support: by that date, WHO had delivered more than 3,300 metric tonnes of medicines and medical supplies since April 2023. (emro.who.int)

Malaria, cholera and measles have remained major public-health concerns. In May 2025, WHO reported more than 3.5 million estimated malaria cases and 62,000 cholera cases, alongside measles outbreaks; it also stated that immunization rates had fallen below 50%, compared with 85% before the war. Damaged water and sanitation infrastructure increased outbreak risks, while interrupted vaccination weakened protection against childhood infections. WHO reported that the prolonged cholera outbreak was declared over in March 2026 following a response that included oral vaccination campaigns reaching 24.5 million people. Malnutrition compounded disease risks and generated demand for specialized treatment: WHO-supported services treated more than 118,000 children with complicated severe acute malnutrition between April 2023 and April 2026. (who.int)

Humanitarian Crisis and Displacement

The war that began on 15 April 2023 expanded an already substantial displacement crisis. The International Organization for Migration (IOM) recorded approximately 11.58 million internally displaced people at the January 2025 peak, including people uprooted by earlier conflicts. By August 2026, its monitoring counted 8.58 million internally displaced people and 5.15 million returnees. These figures describe different population categories: declining internal displacement accompanied substantial returns, but did not mean that returnees had regained secure housing, services or livelihoods. New displacement continued elsewhere; IOM recorded approximately 308,000 people displaced from Kordofan between 25 October 2025 and 1 September 2026. (dtm.iom.int)

Cross-border forced migration has extended the emergency into Chad, Egypt, Ethiopia, South Sudan and other receiving countries. UNHCR’s 2026 situation appeal reported 4.4 million refugees, asylum-seekers and returnees who had sought safety across seven countries. This total includes Sudanese refugees as well as nationals of neighbouring countries returning from Sudan, and therefore is not a count solely of Sudanese refugees. Egypt’s government estimated that 1.5 million Sudanese had entered Egypt since the conflict began. UNHCR provides protection and relief, while receiving communities also bear the costs of accommodating displaced populations; the agencies’ July 2025 assessment described host countries as increasingly strained and refugee assistance as severely underfunded. (unhcr.org)

Food insecurity has varied sharply by locality and assessment period. An Integrated Food Security Phase Classification (IPC) assessment classified El Fasher in North Darfur and Kadugli in South Kordofan as experiencing Famine in September 2025, with conditions projected to persist through January 2026. The subsequent nationwide assessment for February–May 2026 estimated that 19.5 million people, or 41 percent of the population, faced IPC Phase 3 or worse acute food insecurity, including 135,000 in household-level Phase 5, termed “Catastrophe.” That assessment classified no area in Famine but identified 14 areas at risk. Household Catastrophe and area-level Famine are distinct classifications, so the absence of an area-level designation did not indicate the disappearance of starvation. Conflict, displacement and disrupted markets constrained food access; approximately 825,000 children were expected to experience severe acute malnutrition during 2026. (ipcinfo.org)

The World Food Programme reported reaching more than four million people monthly in 2026, including two million in Darfur and 825,000 in Kordofan, while funding shortfalls forced it to prioritize the most severely affected communities. Access depended on negotiated permissions and secure transport routes. On the night of 2 June 2025, a 15-truck WFP–UNICEF convoy awaiting clearance to proceed to El Fasher was attacked at Al Koma, North Darfur. Five convoy members were killed, others injured, and trucks and supplies destroyed. Kristine Hambrouck, then acting United Nations Resident and Humanitarian Coordinator in Sudan, called for an independent investigation and safe, unimpeded access, describing the attack as a violation of international humanitarian law. (wfp.org)

Displacement has also altered urban settlement and the labour market. A UNDP–International Food Policy Research Institute survey of 3,000 urban households, conducted between May and July 2024, found that 31 percent had been displaced and full-time employment had fallen by half. Loss of work and livelihood assets weakened households’ capacity to support themselves, while displaced populations increased demands on host communities’ services and natural resources. Returns brought further obstacles: a joint agency assessment in July 2025 found ruined infrastructure in Khartoum, Sennar and Al Jazirah, schools and hospitals converted into collective shelters, and lost civil documents preventing access to services. These conditions made return a separate stage of the humanitarian emergency rather than an automatic restoration of pre-war living conditions. (undp.org)

Cultural Heritage and Arts

Sudan’s Kushite monuments form two distinct UNESCO World Heritage properties. Gebel Barkal and the Sites of the Napatan Region, inscribed in 2003, comprises Gebel Barkal, El-Kurru, Nuri, Sanam and Zuma. Their temples, pyramids and decorated burial chambers preserve evidence of religious practice and royal funerary architecture. Gebel Barkal’s sacred status is expressed particularly clearly in the rock-cut temple of Mut, where a relief depicts King Taharqa worshipping Amun inside the mountain. Archaeological Sites of the Island of Meroe, inscribed in 2011, combines the royal city and cemeteries of Meroë with the religious centres of Naqa and Musawwarat es-Sufra. Alongside the pyramids, temples, domestic buildings and water-management installations provide evidence for settlement, engineering and exchanges between African and Mediterranean artistic traditions. (whc.unesco.org)

The Sudan National Museum in Khartoum opened to the public in 1971, following the international campaign to rescue Nubian monuments threatened by the Aswan High Dam reservoir. Its collections brought together archaeological material from prehistoric, Nubian, Kushite, Christian and Islamic periods. The museum grounds incorporated rescued portions of the temples of Buhen and Semna, while wall paintings from Faras represented medieval Nubian Christianity, including an eleventh-century depiction of the Archangel Michael. These relocated monuments and paintings made the museum a repository not only of excavated objects but also of architectural and religious art from sites subsequently submerged. (unmis.unmissions.org)

Sudanese music developed through interaction between local performance traditions, religious singing and urban recording industries. Haqiba, which emerged in Omdurman in the 1920s, adapted the vocal style of devotional madeih to songs performed by a soloist and chorus, principally accompanied by tambourine. Lyrics occupied a central place; Muhammad Ahmad Sarour and Khalil Farah were among its pioneers. Commercial recordings circulated the repertoire, and Omdurman radio, established in 1941, subsequently disseminated newer orchestral styles. Later performers included Muhammad Wardi and Sharhabil Ahmad, whose electric-instrument ensembles helped develop “Sudanese jazz.” During the 1970s, Abdel Qadir Salim and other musicians brought Kordofan’s regional styles into the capital’s popular repertoire. (riftvalley.net)

Regional intangible cultural heritage also survives through storytelling, sung poetry and craft knowledge. In Darfur and Kordofan, women known as hakamat recount histories and express praise, criticism and social expectations through songs rich in local vocabulary and metaphor. Their performances transmit memories of pastoral life and community customs between generations. In northern Sudan, community displays at Abri’s House of Heritage have connected archaeological history with living traditions through objects such as the tambour stringed instrument and carved wooden serving bowls. Modern visual art pursued related questions of cultural identity: Ibrahim El-Salahi, a leading figure of the Khartoum School after independence in 1956, combined Arabic calligraphy with African ornament and sculptural forms.

The war beginning in April 2023 damaged both archaeological collections and the institutions sustaining contemporary cultural production. UNESCO’s preliminary assessment of the National Museum on 28 March 2025 confirmed destroyed exhibition galleries, systematic looting and severe infrastructure damage. A subsequent inspection found damaged roofing and collapsed wall sections in an annex store containing more than 10,000 objects from the Nubian rescue campaign, leaving surviving material exposed to weather and further theft. UNESCO also reported the packing and securing of endangered collections at five archaeological museums and the inventorying and digitization of more than 1,700 objects. (unesco.org)

Protection efforts have combined physical stabilization, collection documentation and measures against illicit trafficking. The National Museum emergency programme included cleaning and conserving surviving objects, recording missing material, reinforcing damaged storage buildings and replacing shelving. On 6 July 2026, UNESCO reported that an Italian-supported museum project had documented more than 2,000 objects and trained over 500 museum professionals, customs officers, law-enforcement personnel and judicial officials; national authorities had recovered 570 stolen museum objects. Separately, the British Council-supported Safeguarding Sudan’s Living Heritage project developed a digital platform documenting community traditions, crafts and performances, working with museums and cultural groups inside and outside Sudan. (unesco.org)

Environment, Desertification and Water Resources

Desertification reduces the productivity of cropland and pasture in northern Sudan, North Kordofan and North Darfur through interacting climatic and land-use pressures. The United Nations Environment Programme’s 2007 assessment estimated that the boundary between desert and semi-desert had shifted southward by 50–200 kilometres since rainfall and vegetation records began in the 1930s. This was a historical estimate, not a uniform annual rate of advance. Reduced rainfall, vegetation clearance, overgrazing and poorly managed cultivation leave soils exposed to wind and water erosion, diminishing agricultural productivity and increasing sediment accumulation in water bodies. UNEP’s 2020 environmental assessment identified overworked soils in mechanized farming areas and widespread erosion, illustrating that productive land can deteriorate without becoming visibly desert. (thegef.org)

The Nile supplies most of Sudan’s surface freshwater, making water management dependent on upstream flows as well as domestic rainfall. The Agreement for the Full Utilization of the Nile Waters, signed with Egypt in Cairo on 8 November 1959, allocated Sudan 18.5 billion cubic metres annually and Egypt 55.5 billion cubic metres, measured at Aswan. These allocations used an estimated average annual flow of 84 billion cubic metres, less 10 billion cubic metres for reservoir losses. The agreement also established a permanent joint technical commission. It was a bilateral arrangement rather than a settlement among all states in the drainage basin; Ethiopia was not a signatory. The allocations are treaty entitlements, not measurements of Sudan’s actual annual withdrawals, which depend on infrastructure, demand and river conditions. (treaties.un.org)

Ethiopia’s Grand Ethiopian Renaissance Dam introduced a major upstream storage and flow-regulation facility on the Blue Nile. Egypt, Ethiopia and Sudan signed a Declaration of Principles in Khartoum on 23 March 2015, addressing cooperation, equitable and reasonable utilization, prevention of significant harm, dam safety, and cooperation over filling and operation. Sudan’s position has distinguished possible benefits from operational risks: in its 2021 submission to the United Nations Security Council, it recognized potential reductions in flood damage and sedimentation, alongside more reliable water for irrigation and electricity generation. It also emphasized that coordinated releases and timely data exchange were necessary for operating the downstream Roseires reservoir safely. The dispute therefore concerns reservoir filling, drought-period releases, information sharing and the legal force of operating rules, rather than simply the presence of a hydroelectric dam. (digitallibrary.un.org)

Away from perennial rivers, rural settlements and livestock depend heavily on groundwater, wells, seasonal watercourses and hafirs, reservoirs that collect rainfall and runoff. The Nubian Sandstone Aquifer System is shared with Egypt, Libya and Chad; its substantial stored water must be distinguished from annual replenishment. According to the British Geological Survey’s Sudan groundwater atlas, sandstone boreholes generally range from 40 to 400 metres deep, while recharge occurs through rainfall infiltration, wadi runoff and, locally, river leakage. The Um Ruwaba aquifer, important in Kordofan and other central and southern areas, generally has lower productivity and limited rainfall recharge, and is used mainly for domestic supply and livestock watering. Access also depends on water quality and functioning pumps: some coastal groundwater is brackish, and UNICEF documented generator installation and handpump rehabilitation to restore supplies in conflict-affected communities in 2024. (wedocs.unep.org)

Climate change compounds exposure to drought and flooding, while rainfall variability, inadequate infrastructure and conflict shape their consequences. Rain-fed crops and grazing systems are vulnerable to prolonged dry spells; floods destroy crops, damage water facilities and displace households already affected by insecurity. A 2021 World Bank assessment reported that the 2020 floods affected more than 800,000 people across all 18 states. In August 2024, heavy rainfall and flooding caused the collapse of the Arba’at dam near Port Sudan. At a United Nations briefing on 27 August, authorities’ estimates indicated that approximately 50,000 people west of the dam had suffered damaged or destroyed homes. Damage to this important freshwater source also disrupted Port Sudan’s water supply, demonstrating how a flood can produce a subsequent water-access crisis. These events illustrate vulnerability; they do not, by themselves, establish the extent of climate change’s contribution to an individual disaster. (documents.worldbank.org)

Foreign Relations and International Status

Sudan joined the United Nations on 12 November 1956 and the Arab League on 19 January that year. It is also a member state of the African Union (AU), although membership and participation in the organization’s activities are distinct. Following the military takeover of October 2021, the AU Peace and Security Council decided at its meeting on 26 October to suspend Sudan’s participation until the restoration of the civilian-led transitional authority. This restricted its involvement in AU institutions without ending its international sovereignty or UN membership. (un.org)

Relations with the United States have alternated between isolation and rapprochement. Washington designated Sudan a state sponsor of terrorism in 1993 and imposed broad economic sanctions in 1997, including restrictions on transactions with the Sudanese government. The principal trade and financial restrictions were revoked effective 12 October 2017; the separate terrorism designation was rescinded on 14 December 2020. These decisions did not abolish every Sudan-related restriction: Darfur sanctions remained a separate legal framework, and Executive Order 14098 of 4 May 2023 authorized sanctions against persons destabilizing Sudan or obstructing a democratic transition. China, which established diplomatic relations with Sudan on 4 February 1959, developed a bilateral relationship encompassing petroleum, agricultural products, machinery and electrical equipment. (2021-2025.state.gov)

International sanctions differ in geographical scope and purpose. The UN Security Council imposed an arms embargo on non-governmental actors in Darfur in 2004, expanding it in 2005 to encompass the parties to the N’Djamena ceasefire agreement and other belligerents there. Resolution 1591 also established targeted asset freezes, travel restrictions and a monitoring committee assisted by experts; this was not a comprehensive worldwide trade embargo against Sudan. The European Union subsequently developed additional restrictions addressing the post-2023 conflict. On 13 July 2026, it adopted prohibitions on purchasing, importing or transferring Sudanese gold, together with restrictions on supplying mercury and cyanide used in gold extraction and on related services, explicitly targeting sources of war financing. (main.un.org)

Relations with neighbouring states involve unresolved territorial questions and cross-border security. Clashes with Ethiopia intensified in late 2020 over al-Fashaga, fertile borderland cultivated by Ethiopian farmers but claimed by Sudan under the early-twentieth-century boundary settlement. Relations with South Sudan remain affected by the disputed status of Abyei: the Security Council established the United Nations Interim Security Force for Abyei on 27 June 2011 to support security and demilitarization, without determining the territory’s final sovereignty. Chad’s frontier has also acquired wider strategic importance during the current war. In its 2024 report, the UN Panel of Experts described military supply networks reaching the Rapid Support Forces (RSF) through Chad, Libya and South Sudan. It assessed allegations of arms deliveries through Am Djarass in eastern Chad as credible, while recording the United Arab Emirates’ denial of involvement in arms shipments. (government.nl)

Diplomacy after the outbreak of war on 15 April 2023 initially centred on Saudi-American mediation in Jeddah. On 11 May, representatives of the Sudanese Armed Forces and RSF signed a declaration committing them to protect civilians, facilitate humanitarian relief and pursue ceasefire negotiations; the declaration itself was not a permanent ceasefire or political settlement. The AU’s parallel roadmap emphasized coordinated mediation, civilian protection and an inclusive political transition. UN engagement changed when, following a request from the Sudanese authorities, the Security Council terminated the United Nations Integrated Transition Assistance Mission in Sudan effective 3 December 2023, transferring appropriate tasks to UN agencies. On 12 September 2025, Egypt, Saudi Arabia, the United Arab Emirates and the United States—the diplomatic “Quad”—proposed an initial three-month humanitarian truce, followed by a permanent ceasefire and a civilian-led transition. These were proposed negotiating stages, not evidence that the parties had implemented a peace agreement. (2021-2025.state.gov)

Research and Open Questions

Research on ancient Kush increasingly examines settlements, production and everyday life rather than royal monuments alone. At Jebel Barkal, the joint Sudanese–University of Michigan project has used magnetometry, ground-penetrating radar and excavation to investigate the city surrounding the temples and palaces. Geoff Emberling’s 2024 report described a 1.5-metre-deep sounding containing occupation layers extending from approximately 100 BCE back to 700 BCE, demonstrating that earlier Napatan settlement lay beneath the more visible Meroitic remains. Concentrations of cooking installations raised a specific interpretive question: did these buildings supply workers and traders, or temple and palace personnel? These alternatives remain hypotheses rather than established identifications. (lsa.umich.edu)

War has made the continuation of archaeological research uneven, rather than stopping all work. The Jebel Barkal team continued analysing and publishing material during 2024 and undertook another field season in April 2025. Nevertheless, damage to museums and disruption of access threaten the collections, archives and contextual records needed to compare sites. Sudanese antiquities specialist Shadia Abdrabo’s database project, reported in November 2025, sought to bring archaeological sites, museum collections and historical archives into an online record. A complementary research agenda at Musawwarat es-Sufra, developed by the German Archaeological Institute and Sudanese partners for 2020–2025, investigates pastoralist communities through field survey, remote sensing and collaboration with local residents, addressing populations underrepresented in monument-centred accounts of Kush. (sites.lsa.umich.edu)

Debate over Darfur concerns the mechanisms connecting environmental pressures with political violence. In his 2007 essay “Is Climate Change the Culprit for Darfur?”, Alex de Waal rejected a simple causal progression from climate change to war. He distinguished drought, famine, migration and armed conflict, arguing that governmental neglect, economic marginalization and weakened community authority mediated their relationship. His chronology was important: southward migration and changing land use preceded the large-scale violence by decades. In this interpretation, competition over pasture and farmland created disputes that political actors could mobilize; it did not make war inevitable. The research question is therefore how resource pressures interacted with institutions and political decisions, rather than whether ethnicity or environmental scarcity alone “caused” the conflict. (africanarguments.org)

Analysis of the war beginning in April 2023 similarly distinguishes immediate triggers from longer-term structures. The Center for Strategic and International Studies identified negotiations over integrating the Rapid Support Forces into the Sudanese Armed Forces as an immediate source of confrontation, while emphasizing the RSF’s access to gold-mining revenues as a means of financing recruitment and maintaining an independent military organization. This account treats security-sector integration as a redistribution of command, income and political power, not merely an administrative merger. It leaves an important institutional question: what arrangements could place armed organizations and their commercial resources under effective civilian authority without preserving competing military centres of power? (csis.org)

Reliable demographic and economic measurement is another major research constraint. UNFPA’s country evaluation identified the 2008 census as the foundation of population statistics. Wartime surveys must account for subsequent displacement and changing access to households. The World Bank’s May–July 2025 Welfare Monitoring Survey interviewed 3,129 Sudanese respondents across all 18 states and a separate sample of 1,112 refugee households. Its Sudanese sampling frame covered adults with mobile-phone access; weights used the 2022 Labour Force Survey and July 2025 displacement estimates. Consequently, its coverage was not equivalent to a new census, and households without reachable phones remained a methodological concern. Economic monitoring also uses indirect evidence: the Bank’s October 2025 assessment employed satellite night lights to examine geographical shifts in activity. These distinctions matter when estimating service demand, allocating relief or interpreting national output figures. (unfpa.org)

The future constitutional order remains an open institutional problem. In September 2025, International Crisis Group analyst Shewit Woldemichael interpreted the RSF’s establishment of a rival administration in Nyala as deepening fragmentation and increasing the risk of de facto partition. Her analysis distinguished claims to national legitimacy from the capacity to operate a functioning administration. Questions for any durable settlement therefore extend beyond a ceasefire: whether rival governing structures can be reconciled, how civilian authority can become effective, and whether territorial control will harden into lasting political division. These are conditional possibilities, not settled forecasts about Sudan’s eventual constitution or borders. (crisisgroup-staging.sbx.so)
