      "text": "Yemen (officially the Republic of Yemen) is a country at the southwestern corner of the Arabian Peninsula, bordering Saudi Arabia to the north and Oman to the east, with coasts on the Red Sea and the Gulf of Aden. Its territory includes the Socotra archipelago in the Indian Ocean and lies beside the Bab al-Mandab strait, one of the world's key shipping chokepoints. The land ranges from rugged western highlands and a hot coastal plain to the desert margins of the east, and most of it is arid, with rain concentrated in the highlands.\n\nYemen has long been significant in the Arabian world. Its pre-Islamic kingdoms of Saba and Himyar grew rich from the incense trade, and later Zaydi imamates, Rasulid rulers and the coffee trade through the port of Mocha shaped its history. After the country was divided into northern and southern states and then reunified in 1990, a conflict that escalated sharply from 2014 drew in the Houthi movement, a Saudi-led coalition and rival internal forces. The war has produced one of the world's largest humanitarian crises. A 2022 truce broke down in 2026, and UN officials have warned of a return to full-scale war. Reports on the current situation change quickly, so this entry dates its claims and attributes contested accounts to the parties that make them.\n\nThe entry covers the country's geography and environment, its ancient and Islamic-era history, the state-building and civil conflicts of the modern period, the current war and its political, humanitarian, economic and strategic dimensions, and the country's culture and society."

      "text": "Yemen occupies the southwestern corner of the Arabian Peninsula in western Asia. Its mainland borders Saudi Arabia to the north and Oman to the east and northeast, with the Red Sea to the west, the Gulf of Aden to the south, and the Arabian Sea beyond its southeastern coast. The United States Library of Congress’s 2008 country profile gives an area of approximately 527,970 square kilometres, including offshore islands, and a coastline of 1,906 kilometres. Yemen’s territory therefore encompasses both the Arabian mainland and islands extending into the northwestern Indian Ocean. (tile.loc.gov)\n\nAt the mainland’s southwestern extremity, the Bab al-Mandab strait separates Yemen from the African coast and connects the Red Sea with the Gulf of Aden. Approximately 29 kilometres wide at its narrowest point, it forms the southern entrance to the maritime route through the Red Sea and Suez Canal. The Yemeni island of Perim, also called Mayyun, divides the strait into eastern and western channels. Kamaran lies farther north in the Red Sea, off Yemen’s western coast, rather than within the strait itself. These islands occupy strategically important positions along Yemen’s maritime approaches; the shipping and military implications of that geography are distinct from their territorial status. (eia.gov)\n\nThe Socotra archipelago extends Yemen’s territory well beyond the mainland. Situated near the mouth of the Gulf of Aden in the northwestern Indian Ocean, the approximately 250-kilometre-long group comprises four islands—Socotra, Abd al-Kuri, Samha and Darsa—and two rocky islets. UNESCO’s 2008 evaluation places the principal island about 450 kilometres south of mainland Yemen and 330 kilometres east of Cape Guardafui on the African coast. Other Yemeni offshore territories include the Zubayr and Zuqar–Hanish groups in the Red Sea. Their ownership was addressed in the Eritrea–Yemen arbitration: the award of 9 October 1998 recognized Yemeni sovereignty over both groups, while assigning several islands closer to Eritrea to that country. A second award, issued on 17 December 1999, delimited the maritime boundary. (whc.unesco.org)\n\nThe principal settlement of Yemen’s northern boundary was the International Boundary Treaty signed at Jeddah on 12 June 2000, during the reign of King Fahd of Saudi Arabia and the presidency of Ali Abdullah Saleh in Yemen. It entered into force on 4 July 2000. The treaty reaffirmed the validity of the 1934 Treaty of Taif and its boundary reports, and supplied coordinates for the remaining land boundary and the maritime boundary in the Red Sea. It characterized the agreed frontier as definitive and permanent. Consequently, historically contested border districts and subsequent disputes over border security should not be described as an internationally unresolved boundary: the treaty settled the interstate territorial dispute. (un.org)\n\nYemen and Oman signed their international boundary agreement at Sana’a on 1 October 1992, providing for surveys, boundary pillars and arrangements governing grazing, movement and water use in the frontier zone. A separate maritime delimitation agreement was signed at Muscat on 14 December 2003 and entered into force on 3 July 2004. Yemen’s maritime claims comprise a 12-nautical-mile territorial sea, a contiguous zone extending to 24 nautical miles from the baselines, and a 200-nautical-mile exclusive economic zone. Under the United Nations Convention on the Law of the Sea, sovereignty in the territorial sea differs from the resource rights and jurisdiction exercised in the exclusive economic zone, where other states retain navigation rights. The 200-nautical-mile distance is an outer limit, not an automatic boundary where neighbouring states’ entitlements overlap. (un.org)"

      "heading": "Physical geography: highlands, coastal plains and deserts",
      "text": "Yemen’s western highlands form a deeply dissected mountain belt extending from the Sa‘dah region in the north through the central uplands to Taiz in the south. Much of the inhabited upland terrain lies between 1,800 and 2,500 metres, but ridges and summits rise substantially higher. Jabal al-Nabi Shu‘ayb, west of Sana’a, reaches approximately 3,666 metres and is the highest mountain in the Arabian Peninsula. The highlands are not a continuous, level plateau: steep mountain blocks alternate with intermontane plains and basins, including those of Sa‘dah, Amran, Sana’a, Dhamar and Yarim. Sana’a occupies a mountain valley at about 2,200 metres. These basins provide comparatively extensive land for cultivation and settlement within otherwise rugged country; the western uplands contain much of Yemen’s population, with Sana’a, Ibb and Taiz among their principal urban centres. (fao.org)\n\nWest of the mountain escarpment, the Tihama is a low, gently sloping coastal plain along the Red Sea. A Yemeni country report published by the Food and Agriculture Organization describes it as approximately 420 kilometres long and 20–50 kilometres wide, rising from sea level to roughly 300 metres at the foothills. Its hot, lowland environment contrasts sharply with the cooler highlands. Wadis descending from the mountains cross the plain, notably the Mawr, Sardud, Siham and Zabid. Although rainfall on the coast is limited, runoff from the wetter uplands supports agriculture through floodwater diversion, or spate irrigation. The agricultural landscape therefore depends partly on rain falling outside the plain itself. Along the southern coast, lowland plains are interrupted where hills and mountains approach the sea, rather than forming an equally continuous coastal strip. (fao.org)\n\nEastward, the western mountain belt gives way to lower slopes, rocky plateaus and desert country. The Hadramawt plateau is cut by an extensive network of wadis—valleys and channels whose surface flows are generally intermittent. An FAO physiographic classification places elevations within this region at approximately 600 metres in the valleys and up to 1,600 metres on the higher watershed areas. Wadi Hadramawt is a major axis of settlement and agriculture within this otherwise dry plateau landscape. Around Shibam, flood-irrigated fields form an economic unit with the town, supplying both agricultural produce and sediment used in earthen construction. The same valley setting exposes settlements to destructive floods: an earlier settlement at Shibam was partly destroyed in 1532–1533, and another major flood affected the area in October 2008. (fao.org)\n\nThe sandy Ramlat al-Sab‘atayn lies between the western mountain massif and the eastern plateau. Farther north and northeast, Yemen reaches the southern margins of the Rub‘ al-Khali, or Empty Quarter, which extends into Saudi Arabia. These interior landscapes include both rocky desert surfaces and extensive sand-covered areas; they should not be understood as a single uninterrupted dune field. Vegetation is sparse away from channels receiving runoff from adjacent uplands. The mountains also organize drainage: western valleys descend toward the Red Sea, southern valleys toward the Gulf of Aden and Arabian Sea, while other catchments drain inland toward the desert. Flood flows commonly rise abruptly and recede quickly, leaving dry channels or only minor base flows between events. (fao.org)\n\nTerrain has encouraged distinctive forms of cultivation and constrained transport. On steep highland slopes, stone-supported terraces create cultivable surfaces, retain soil and slow runoff, allowing rainfed farming where unmodified slopes would lose water and sediment rapidly. Highland crops include sorghum, wheat, barley and lentils. Roads must connect dispersed settlements across mountain barriers, making land transport a persistent constraint on rural access. The Sana’a–Hodeidah corridor illustrates the link between upland population centres and coastal ports: a World Bank appraisal dated September 22, 1987, specified rehabilitation of 222 kilometres, including the Manakhah spur, and repairs to flood-damaged roads elsewhere. Its combination of mountain access and flood-repair requirements reflects two recurring physical constraints on Yemen’s transport infrastructure. (fao.org)"

      "heading": "Geology, tectonics and volcanism",
      "text": "Mainland Yemen occupies the southwestern edge of the Arabian Plate, beside two divergent boundaries: the Red Sea separates Arabia from the Nubian Plate, while the Gulf of Aden separates it from the Somali Plate. These spreading systems connect with the East African Rift in the Afar region. Their development involved stretching and thinning of continental crust, movement along normal faults, and eventually the formation of oceanic crust by seafloor spreading. This tectonic setting also distinguishes mainland Yemen from Socotra, which lies on the southern, Somali-Plate side of the Gulf of Aden. Regional reconstructions associate the breakup with Oligocene–Miocene extension and the influence of hot mantle beneath Afar; the two basins did not open simultaneously along their entire lengths. (pubblicazioni.unicam.it)\n\nMuch of the western highlands consists of the Yemen Traps, a thick succession of continental flood basalts and associated silica-rich volcanic rocks. These belong to the same broad volcanic province as the Ethiopian flood basalts, emplaced before the intervening seas separated the two regions. The volcanic succession in western Yemen reaches approximately 1–2.5 km in thickness. Radiometric dating reported in 1996 placed the beginning of basaltic eruptions at about 30.9 million years ago in northwestern Yemen and 29.2 million years ago in southwestern Yemen; rhyolitic activity began around 29.0–29.3 million years ago, and the youngest dated flood-volcanic units were approximately 26.9–26.5 million years old. Repeated eruptions built layered lava plateaus, while explosive silicic eruptions deposited extensive sheets of welded volcanic debris, or ignimbrite. The sequence therefore records both basaltic lava emplacement and the evolution of magma within continental crust, rather than a single uniform eruption episode. (pubs.usgs.gov)\n\nYounger volcanism produced separate volcanic fields superimposed on this older landscape. Around Dhamar, a field extending approximately 80 km eastward contains several stratovolcanoes and numerous youthful cones, with basaltic lava flows overlying older rhyolitic flows. Its geology differs in scale and age from the broad Oligocene flood-basalt succession. Socotra, by contrast, is principally a fragment of continental basement and sedimentary cover, not an island built by recent oceanic volcanism. Its crystalline core is overlain by rocks ranging from Triassic to Miocene age; thick Paleocene–Eocene limestones form much of the plateau surface. Reconstructions place Socotra beside Dhofar in present-day Oman before Gulf of Aden rifting. Oligocene–Miocene extension created fault-bounded sedimentary basins, and subsequent exposure permitted the development of caves and other karst features in the limestone. (volcano.si.edu)\n\nDestructive earthquakes also occur within the mainland, away from the offshore spreading axes. On 13 December 1982, a magnitude-6.0 earthquake struck the Dhamar region, approximately 75 km south of Sana'a, causing widespread destruction and substantial loss of life. A subsequent investigation deployed eleven portable seismographs to locate aftershocks; their source mechanisms indicated normal faulting along northwest-striking planes, consistent with crustal extension. The earthquake also triggered landslides and produced north-northwest-trending ground cracks in zones reaching approximately 15 km in length. These observations demonstrate that inland faults can generate severe local shaking even where the principal plate boundaries lie offshore. (pubs.usgs.gov)\n\nThe clearest recent eruption record comes from Yemen's Red Sea islands. On 30 September 2007, Jebel at Tair erupted, sending lava across the northeastern part of the island into the sea and killing members of its military garrison; activity continued through at least late November. Submarine eruptions in the Zubair group subsequently formed Sholan island in 2011–2012 and Jadid island in 2013. Satellite observations documented new land emerging where magma reached shallow water, illustrating how active rift volcanism can rapidly alter the offshore landscape. These events provide direct evidence of continuing volcanic hazards, including lava flows, eruption plumes and explosive activity where erupting magma interacts with seawater. (volcano.si.edu)"

      "heading": "Climate, seasonal rain and temperature",
      "text": "Yemen’s climate is predominantly arid or semi-arid, but elevation produces marked contrasts between hot coastal lowlands and cooler highlands. Mean temperatures in the highlands range from below 15°C in winter to about 25°C in summer, compared with approximately 22.5°C to 35°C in the coastal lowlands. Winter temperatures can fall below freezing on the high plateaus, occasionally damaging crops through frost; summer temperatures can exceed 40°C in the eastern desert. Coastal humidity adds to the thermal contrast: mean relative humidity can exceed 80% near the sea, compared with about 30% in the arid east. Annual rainfall is similarly uneven, ranging from less than 50 mm in the driest coastal and interior areas to as much as 1,000 mm around Ibb in the southern uplands; Sana’a receives approximately 250 mm annually. These figures describe regional climatic conditions rather than uniform national averages. (climateknowledgeportal.worldbank.org)\n\nThe highlands generally have two rainy seasons: the saif, broadly March–May, and the kharif, July–September. Spring rainfall is associated with the Red Sea Convergence Zone, where converging airflows supply moisture to western Yemen. Summer rainfall accompanies the northward movement of the Intertropical Convergence Zone and regional monsoon circulation; its influence lasts longer in southern districts as the convergence zone subsequently retreats southward. Rain commonly falls in short, intense storms rather than prolonged, evenly distributed precipitation. Mountain slopes receive substantially more rain than adjoining plains, while rainfall diminishes toward the interior. Consequently, seasonal totals alone do not determine agricultural conditions: the timing and spacing of storms govern crop establishment, and intense downpours can produce damaging runoff even during an otherwise dry season. (fao.org)\n\nThe World Bank’s 2023 climate-risk profile estimated that national mean annual temperature rose by 0.42°C per decade during 1971–2020. Warming was geographically uneven: Al Jawf recorded an increase of 0.58°C per decade, compared with 0.16°C in Aden. Minimum temperatures rose faster nationally than maximum temperatures, indicating increasingly warm nights. Rainfall trends were less uniform. The estimated national decline of 6.25 mm per decade was not statistically significant, although decreases along parts of the western and southwestern coast were significant. Under the high-emissions SSP3-7.0 scenario, the profile projected approximately 1.64°C of additional mean warming for 2040–2059 relative to 1995–2014. For Socotra, the same scenario projected sea-level rise of about 0.25 m by 2050 and 0.77 m by 2100, increasing exposure to inundation, erosion and saltwater intrusion. (climateknowledgeportal.worldbank.org)\n\nFuture rainfall remains more uncertain than future warming. The World Bank’s 2024 climate and development assessment considered both wetter and drier outcomes, while identifying the combination of more intense precipitation and longer dry intervals as a major risk. Higher temperatures increase evaporative losses, so increased rainfall would not necessarily remove drought stress. Rainfed cereals are particularly sensitive to rainfall arriving too late or failing during crop development. In its June 4, 2026 country brief, the Food and Agriculture Organization estimated Yemen’s 2025 cereal production at approximately 400,000 tonnes, below average: prolonged dry weather and high temperatures reduced planted areas and yields, alongside conflict-related and economic constraints. Livestock are also exposed through fodder availability; highland herds traditionally depend on cut fodder during the rainy season and crop stubble after harvest. (worldbank.org)\n\nHeat and drought affect public health through both direct exposure and disruptions to food and water supplies. Prolonged temperature extremes increase illness and mortality, while reduced agricultural production can aggravate malnutrition. Drought-related water scarcity, together with inadequate sanitation, increases risks from waterborne disease; flooding can contaminate supplies and interrupt medical services. These climatic pressures interact with, rather than replace, the effects of conflict, poverty and damaged infrastructure. The Red Cross Red Crescent Climate Centre’s 2024 assessment identified these combined pathways as important health risks, distinguishing climate-related losses in agricultural productivity from the broader economic and conflict-driven causes of Yemen’s food insecurity.

      "heading": "Water scarcity and groundwater depletion",
      "text": "Yemen is among the world’s most water-scarce countries. In March 2023, the Food and Agriculture Organization (FAO) estimated annual renewable freshwater availability at 86 cubic metres per person, far below the commonly used absolute-scarcity threshold of 500 cubic metres. With no permanent rivers, supplies depend on rainfall, seasonal floodwater and groundwater extraction. Wells serve domestic, agricultural and livestock needs, while urban households obtain water through public networks, private wells and tanker deliveries. Agriculture accounted for approximately 90 per cent of withdrawals before the war, making irrigation the principal source of pressure on available resources. (fao.org)\n\nDepletion is particularly pronounced in the highland aquifers. FAO reported annual water-table declines of 2–6 metres in affected areas of the Sana’a, Sa’dah, Rada’a, Taiz and Amran basins in 2023. In the Sana’a basin, wells averaged about 400 metres deep, with some reaching 700 metres or more; qat cultivation accounted for an estimated 30 per cent of water drawn from the basin. Pumping for farms and urban supply therefore competes for the same underground reserves. Falling levels reduce spring flows and increase pumping costs, while excessive extraction in coastal areas allows saline water to enter freshwater aquifers. In March 2024, FAO also identified expanding, insufficiently regulated solar-powered pumping as an additional driver of depletion: cheaper energy does not itself reduce the volume extracted. (fao.org)\n\nTraditional water management combines hillside terraces, cisterns, ponds, diversion weirs and small dams. Terraces retain rainfall and soil on cultivated slopes; underground cisterns and reservoirs store runoff for later use. Along wadis and coastal plains, spate irrigation diverts short-lived flood flows into fields, also replenishing shallow groundwater. These systems require maintenance of retaining walls, channels and storage structures. FAO documented deteriorating terraces and neglect of traditional systems before the present war, alongside increasing dependence on groundwater. Rehabilitation programmes have subsequently rebuilt terraces, restored on-farm storage and underground cisterns, and repaired flood-diversion structures and shallow wells. (fao.org)\n\nThe war since 2015 has compounded physical scarcity with failures of water infrastructure. Damage to wells, pipelines and pumping equipment has been accompanied by fuel shortages, electricity outages, unavailable spare parts and interruptions to staff salaries, leaving households dependent on costly private water trucking. A documented example is the Al-Hamazat system in Sa’dah governorate: UNICEF reported its destruction in 2015, reconstruction in 2017 and destruction again in April 2018, when approximately 7,500 people lost their supply. Its associated solar-power equipment was also severely damaged. These disruptions affect both water production and sewage pumping, so a functioning well alone does not ensure reliable service. (documents1.worldbank.org)\n\nDesalination has remained limited rather than becoming a major alternative to groundwater. A United Nations water-conflict assessment published in 2023 reported its adoption in only two locations and identified high construction and operating costs as constraints, particularly for remote rural communities. Wastewater reuse faces a different infrastructure problem: treatment plants commonly operate without adequate resources and beyond their design capacity, limiting the availability of safely treated effluent for irrigation. Smaller systems have nevertheless been introduced. By March 2023, FAO, with Japanese support, had installed gravity-based wastewater treatment facilities in the Sana’a basin for agricultural reuse; UNICEF also supported wastewater operations and sewer rehabilitation in 15 cities.

      "heading": "Biodiversity, Socotra and marine ecosystems",
      "text": "The Socotra archipelago has exceptionally high endemism, sustained by its long isolation, varied terrain and contrasting local climates. UNESCO inscribed it on the World Heritage List in 2008 under criterion (x), recognizing its importance for biological diversity and threatened species. The inscription records 825 plant species, of which 307—approximately 37%—are endemic, alongside endemicity rates of 90% for reptiles and 95% for land snails. These are the inventories underlying the designation, rather than a continuously updated species census. The property covers 410,460 hectares of terrestrial and marine environments; its terrestrial sanctuaries, national parks and botanical conservation areas encompass approximately three-quarters of the archipelago’s land. Its surrounding waters also support considerable biodiversity, with UNESCO recording 253 reef-building coral species and 730 coastal fish species. (whc.unesco.org)\n\nThe most distinctive endemic plant is the dragon’s blood tree (Dracaena cinnabari), recognizable by its densely branched, umbrella-shaped crown and red resin, historically harvested as a pigment and medicinal material. Native frankincense trees and aloes are other important components of the flora. The conservation problem is not simply the loss of mature trees: livestock grazing inhibits woodland regeneration, while drought and cyclones place additional pressure on existing stands. The wider conflict has also affected resource use without requiring direct fighting on the islands. In 2022, the United Nations Environment Programme reported that expensive and scarce cooking gas was increasing dependence on wood fuel, contributing to deforestation and land degradation. Unplanned development, resource extraction, tourism and invasive species impose further pressures on island habitats. (unep.org)\n\nAlong the mainland, coral reefs are concentrated on the Red Sea coast and around offshore islands, including the Kamaran and Hanish groups. Reef development in the northern Gulf of Aden is more restricted by seasonal upwelling of cold water. Mangroves occupy sheltered stretches of the Tihama shoreline and adjacent islands: Yemen’s fifth national biodiversity report describes most surveyed stands as dominated by Avicennia marina, with Rhizophora mucronata also occurring on Kamaran and near Hodeidah. Together with seagrass beds, these coastal habitats provide breeding and feeding grounds for fish and other marine organisms. Their ecological condition therefore directly affects fisheries, rather than constituting a separate conservation issue. (cbd.int)\n\nYemen’s marine fisheries are predominantly artisanal; the World Bank reported a catch of approximately 160,000 tonnes in 2015. Overexploitation nevertheless predates the war. Yemen’s sixth national biodiversity report recorded declines in valuable lobster, shrimp and some bottom-dwelling fish resources during 2004–2010, while noting insufficient data to quantify the full extent of depletion. Bottom-dragging nets and destructive fishing practices damage seabed habitats; mangrove cutting and livestock browsing reduce coastal vegetation. Sewage, oil spills and sediment washed into coastal waters add pollution pressures. Climate change compounds these risks through warmer seas, rising sea levels and changing storm conditions, affecting coastal habitats and the breeding environments of fish, birds and turtles. Conflict has simultaneously damaged landing facilities and supply chains and weakened the institutions responsible for fisheries management. (worldbank.org)\n\nConservation initiatives combine protected areas, community participation and regional fisheries management, but legal designation does not ensure effective enforcement. UNESCO’s management requirements identify persistent needs for stronger regulatory capacity, monitoring and sustainable finance. In May 2022, UNEP reported that two community-run nurseries on Socotra had planted 2,000 dragon’s blood tree seedlings; the associated programme also supported grazing-management plans and community monitoring of loggerhead turtle nests. In June 2022, the World Bank approved a US$45 million grant for sustainable fisheries in Yemen and regional cooperation in the Red Sea and Gulf of Aden. By November 2025, it reported support for nearly 4,000 fishers and entrepreneurs and rehabilitation underway at nine landing sites. Such programmes operate amid damaged infrastructure, rising fuel costs and weak regulation, which constrain both ecological monitoring and implementation of harvest controls. (whc.unesco.org)"

      "text": "Yemen’s last completed national population census took place on 16–19 December 2004 and counted approximately 19.7 million inhabitants. Subsequent population figures are estimates rather than new enumerations, an important distinction where displacement and fragmented administration complicate local population measurement. The United Nations Population Fund’s 2025 country profile estimated 41.8 million inhabitants, with 41 per cent aged under 15 and only 3 per cent aged 65 or older. Its estimated total fertility rate was 4.4 children per woman. These figures describe a young, rapidly expanding population, but should not be read as a precise count of residents in individual cities or governorates. (unstats.un.org)\n\nArabic is the official language, with Modern Standard Arabic used for official written purposes and regional spoken varieties used in everyday communication. Major dialect groupings include Sanaani, Ta‘izzi-Adeni, Tihami and Hadhrami; “Yemeni Arabic” therefore denotes a collection of varieties rather than a uniform national vernacular. Eastern Yemen and Socotra also preserve Modern South Arabian languages, which are distinct Semitic languages, not Arabic dialects. Mehri, also called Mahri, is spoken in eastern Yemen and neighbouring Oman; Soqotri is spoken on Socotra, while Hobyot occurs near the Yemen–Oman border. A University of Leeds documentation project described these languages in 2014 as facing varying degrees of endangerment. Linguistic research records extensive Arabic borrowing and code-switching, including an Arabic-influenced variety of Soqotri in Hadibo. (ecoi.net)\n\nSana’a, Aden, Taiz and Hodeidah are major concentrations of urban population, but wartime movements have altered their size and settlement patterns. A World Bank assessment published in 2022 estimated Sana’a’s population at more than three million and reported that approximately 500,000 people had moved there since the war began in 2015. Displaced households have sought accommodation with relatives, in rented housing and in expanding informal settlements. Aden has received people displaced from Taiz and Hodeidah, while those cities have themselves experienced destruction and population movements. Consequently, conflict-driven urbanization combines growth in receiving neighbourhoods with departures from exposed districts, increasing demand for services even where housing and municipal infrastructure have been damaged. (thedocs.worldbank.org)\n\nTribal affiliation links kinship, territory, protection and political alliances; it is not simply a genealogical classification. The Hashid and Bakil confederations are especially prominent north of Sana’a, while tribal organization is less influential in cities such as Aden and Taiz. Confederations contain tribes, branches and smaller family groupings, and affiliations have historically changed through alliances and arrangements for protection. Sheikhs and other mediators help negotiate disputes over land, resources and personal injury through customary procedures operating alongside state institutions. These mechanisms can involve agreed compensation and guarantees rather than imprisonment. Tribal mediation has also facilitated wartime prisoner exchanges, illustrating a social function distinct from tribes’ involvement in armed mobilization. (sanaacenter.org)\n\nDescent and occupation have historically shaped social standing, particularly in the northern highlands. Sada, the plural of sayyid, are families claiming descent from the Prophet Muhammad; quda are religious judges and scholars; and qaba’il are tribal members. Service and craft occupations—including barbers, butchers and tanners—were traditionally assigned lower standing and often placed under tribal protection. These distinctions affected marriage relationships as well as social recognition. They are not a uniform hierarchy operating identically throughout Yemen: migration, urban employment and education have changed opportunities and the relationship between inherited status and economic position. (sanaacenter.org)\n\nThe Muhamasheen, whose name means “the marginalized,” are a historically excluded community of dark-skinned Yemenis, also referred to by the derogatory term Akhdam. Descent-based discrimination and exclusion from tribal protection have restricted access to housing, services and mechanisms of redress. A UNICEF-supported survey presented in October 2014 covered approximately 10,000 Muhamasheen households in nine districts of Taiz governorate. Only 9 per cent had piped water in their dwellings, and 39 per cent of children aged 6–17 were enrolled in education, compared with a reported national average of 69 per cent. These are findings from the surveyed communities, not a nationwide enumeration of the group. (minorityrights.org)"

      "heading": "Ancient kingdoms: Saba, Himyar and the incense trade",
      "text": "Saba, known in biblical tradition as Sheba, developed around Marib on the eastern edge of Yemen’s highlands and was a major South Arabian power by the eighth century BCE. Its prosperity combined irrigated agriculture with control of sections of the frankincense and myrrh routes linking southern Arabia to Mediterranean markets. These aromatic resins were valued for temple ceremonies and funerary rites in South Arabia, Egypt, Mesopotamia and Greece. The overland incense route ran from Shabwa, capital of Hadramawt, towards Gaza, with Saba occupying an important position along the network rather than controlling every producing region or commercial stage. In the early seventh century BCE, rulers including Yathaʿamar Watar and Karibʾil Watar expanded Sabaean power through military campaigns and alliances. Marib served as its administrative and economic centre, while Sirwah, approximately 40 kilometres west, was another important royal and religious centre. (whc.unesco.org)\n\nThe Marib dam supported an agricultural economy that was as important as caravan commerce. Its hydraulic works directed seasonal runoff into canals supplying cultivated land north and south of Marib, creating what UNESCO describes as ancient Arabia’s largest artificial oasis. The system transformed irregular floodwater into a resource for settled farming, but depended on maintaining embankments, outlets and distribution channels. Monumental sanctuaries, including Awam and Barʾan, formed part of the same landscape of cities, fields and public works; inscriptions recorded religious dedications, construction and administrative decisions. The dam remained important after Saba lost its political independence: the sixth-century ruler Abraha organized repairs with local tribal assistance and hosted representatives of neighbouring powers at Marib in early 548 CE. (whc.unesco.org)\n\nSaba shared southern Arabia with Qataban, Hadramawt, Maʿin and Awsan, whose territories and relative strength changed through warfare, alliances and annexation. Qataban’s capital, Timna, was a centre of commerce in incense, perfumes and other valuable commodities; Hadramawt’s capital, Shabwa, stood at the beginning of the principal northbound incense route. Maʿin belonged to the group of oasis kingdoms along the desert margin, while Awsan and Qataban were annexed by Hadramawt in the second century CE. These states shared a South Arabian writing system, used to record Sabaean, Minaean, Qatabanian and Hadramitic languages. More than 10,000 monumental inscriptions survive, alongside graffiti and cursive texts written on wooden sticks. Their contents illuminate public administration and private devotion: a limestone incense burner from Timna’s cemetery, for example, bears the personal name Shariqan in Qatabanian. (britishmuseum.org)\n\nHimyar, centred in the southern highlands with its royal capital at Zafar, emerged as the dominant power during the late third and early fourth centuries CE. It absorbed Saba around 275 and Hadramawt around 300, bringing the principal South Arabian kingdoms under one authority. Its rulers subsequently extended their influence into central Arabia, governing some northern territories through the tribal group Kinda. Religious change accompanied political consolidation. The earlier kingdoms had maintained distinct polytheistic pantheons, but during the late fourth and early fifth centuries Himyar’s royal and tribal elites adopted Judaism. Official inscriptions ceased invoking the old deities and instead referred to a single lord of heaven and earth. This epigraphic transformation documents a change in public religion without establishing that every community adopted the same beliefs. (archeologie.culture.gouv.fr)\n\nIn the early sixth century, religious conflict became entangled with intervention by the Christian kingdom of Aksum across the Red Sea. The Jewish ruler Yusuf Asʾar Yathʾar, also known as Dhu Nuwas, attacked Christian communities, including Najran. Aksum’s king Kaleb intervened, defeated Yusuf and installed the Christian ruler Sumyafaʿ Ashwaʿ. The Ethiopian commander Abraha subsequently displaced him and established an increasingly autonomous monarchy. Under Abraha, Christianity became the religion of royal government, while South Arabian political institutions and the Marib irrigation works continued to function. His diplomatic gathering at Marib in 548 included representatives of Aksum, the Byzantine Empire, Persia, al-Hira and the Palestinian phylarchate. (archeologie.culture.gouv.fr)"

The Sasanian governor Badhan accepted Islam during the late 620s or early 630s. Muhammad appointed Muʿadh ibn Jabal to teach the religion, administer justice and collect zakat, while Abu Musa al-Ashʿari served in southern Yemen. Under the early caliphs, appointed governors administered districts centred on Sanaʿa, al-Janad and Hadramawt, alongside continuing tribal authority.

(en.wikipedia.org)\n\nIn 897, Yahya ibn al-Husayn, known as al-Hadi ila al-Haqq, established the Zaydi imamate at Saʿda after invitations from northern tribal leaders. His authority combined religious scholarship, adjudication and military leadership; his writings helped shape Yemeni Zaydi law. The imamate’s territorial reach subsequently expanded and contracted, with interruptions and competing claimants rather than uninterrupted control of Yemen. (islamansiklopedisi.org.tr) In Zaydi doctrine, an eligible imam descended from Muhammad through Fatima and either Hasan or Husayn, possessed learning and piety, and publicly called for allegiance. Succession was therefore not automatically hereditary, although particular families repeatedly supplied imams.

(islamansiklopedisi.org.tr)\n\nThe Rasulids, conventionally dated 1229–1454, emerged from service under the Ayyubids. Their power was concentrated in the Tihama and southern Yemen, with Taʿizz as their capital and Sanaʿa frequently contested with the northern imams. (iranicaonline.org) Their revenues benefited from agricultural production and maritime trade through Aden, connecting the Red Sea with India and the wider Indian Ocean. (en.wikipedia.org) Court scholarship produced unusually detailed records: the future sultan al-Ashraf ʿUmar compiled an agricultural almanac dated 1271, while the fourteenth-century manuscript associated with al-Afdal al-ʿAbbas contained material on taxation, navigation and agriculture, together with vocabularies in Arabic, Persian, Turkic, Greek, Armenian and Mongol. (iranicaonline.org) The Tahirids succeeded the Rasulids in 1454 and ruled until 1517. (en.wikipedia.org) Their architectural patronage included the Amiriya madrasa at Radaʿ, commissioned by Sultan ʿAmir ibn ʿAbd al-Wahhab and completed in August–September 1504; its ground floor incorporated shops, vaulted rooms and a public bath. (archnet.org)\n\nThe Ottoman Empire occupied Aden in 1538 as part of its expansion into the Red Sea and Indian Ocean. (en.wikipedia.org) Ottoman rule depended on garrisons and provincial governors, but repeated Zaydi uprisings prevented secure domination of the highlands. Al-Mutahhar’s revolt in 1567 reduced Ottoman control largely to Zabid and the Tihama before imperial forces recovered territory. Later resistance under al-Qasim ibn Muhammad and his successors culminated in the Ottoman withdrawal in 1635, establishing Qasimid rule.

Highland coffee moved through inland markets to the port, where merchants exchanged it alongside Indian textiles, spices and other goods.

After the Qasimid imams expelled the Ottomans, its trade increasingly looked eastward toward coastal India.

      "text": "British forces captured Aden on 19 January 1839, taking the port from the Abdali sultan of Lahij. Captain Stafford Bettesworth Haines, who had negotiated with the sultan before the occupation, became the British political agent there. Aden’s harbour provided a coaling and provisioning station for steamships travelling between India and the Red Sea. Administered through British India until 1937, the settlement developed into a free port and commercial entrepôt; the opening of the Suez Canal in 1869 strengthened its position on the shipping route between Europe and Asia. On 1 April 1937, Aden became a Crown Colony administered separately from India. (qdl.qa)\n\nThe Aden Protectorate was legally distinct from the colony. Rather than annexing the entire hinterland, Britain concluded agreements with sultans, emirs and sheikhs whose territories provided a buffer around the port and extended eastward into Hadramawt and Mahra. A formal protection treaty with the Mahra Sultanate of Qishn and Socotra in 1886 was followed by further agreements; more than 30 major protection treaties were eventually concluded, the last in 1954. In return for British protection, rulers undertook not to conclude treaties with, or transfer territory to, other foreign powers. They generally retained internal authority, although later advisory agreements increased British involvement in domestic administration. (en.wikipedia.org)\n\nFrom 1937, separate political officers supervised the Western Protectorate from Lahij and the Eastern Protectorate from Mukalla. The eastern territories included the Qu’aiti, Kathiri and Mahra sultanates. This arrangement produced several layers of authority: direct colonial government in Aden, treaty-based supervision over neighbouring states, and local dynastic and tribal administration within them. It differed from the northern Zaydi imamate, ruled by the Hamid al-Din family after the Ottoman withdrawal. Relations between the two systems also involved territorial conflict: before the Anglo-Yemeni Treaty of Friendship and Mutual Cooperation of 11 February 1934, Imam Yahya evacuated protectorate areas his forces had occupied, including Audali territory. (en.wikipedia.org)\n\nEconomic development within the British south was uneven. Aden concentrated shipping services, military employment and industrial investment, including the British Petroleum refinery constructed at Little Aden in 1954. The protectorates remained separately governed territories rather than extensions of the port’s municipal and commercial administration. Aden’s wage-earning workforce also generated organized political opposition: the Aden Trade Union Congress, established in 1956, and its associated People’s Socialist Party became important opponents of British constitutional plans. Strikes and demonstrations challenged the proposed incorporation of the colony into a federation dominated by protectorate rulers. (oac.cdlib.org)\n\nBritain’s approach to decolonization initially centred on federation. Six western protectorate states formed the Federation of Arab Emirates of the South on 11 February 1959; subsequently renamed the Federation of South Arabia, it incorporated Aden in January 1963. Several eastern states remained outside it under the Protectorate of South Arabia. Armed opposition escalated during the Aden Emergency of 1963–1967, involving the National Liberation Front (NLF) and the rival Front for the Liberation of Occupied South Yemen (FLOSY). A grenade attack on the British high commissioner on 10 December 1963 marked the emergency’s beginning; fighting subsequently spread through Aden and rural areas such as Radfan. (govinfo.gov)\n\nBy late 1967, the NLF had gained the advantage over FLOSY, and the federal arrangement failed to provide the basis for independence. Negotiations opened in Geneva on 21 November between a British delegation led by Lord Shackleton and an NLF delegation led by Qahtan al-Shaabi. British forces completed their withdrawal on 29 November, and British sovereignty ended at midnight local time. On 30 November 1967, the former colony and protectorate territories became the independent People’s Republic of South Yemen; its subsequent political development belongs to the history of the separate southern state.

Yahya’s assassination in 1948 was followed by the accession of his son Ahmad, who ruled until September 1962. Ahmad’s successor, Muhammad al-Badr, was overthrown within days of taking power by army officers led by Abdullah al-Sallal, who established the Yemen Arab Republic (YAR). The revolution began an eight-year conflict between republicans supported by Egypt and royalists backed by Saudi Arabia and Jordan. Egyptian forces withdrew in 1967; the eventual settlement incorporated some royalists into republican institutions without restoring the monarchy. Saudi recognition of the republic in July 1970 consolidated that settlement. (tile.loc.gov)\n\nIn the south, independence on 30 November 1967 produced the People’s Republic of South Yemen, with Aden as its capital and the National Liberation Front (NLF) as the governing organization. A radical faction gained control of the NLF in June 1969, and the state adopted the name People’s Democratic Republic of Yemen (PDRY) in 1970. Its Marxist-Leninist political system subsequently centred on the Yemeni Socialist Party (YSP), established in 1978. During the Cold War, the southern republic received arms and support from the Soviet Union, whereas Saudi Arabia supported the northern republic. The division therefore involved separate political institutions and international alignments, not merely an administrative boundary. (1997-2001.state.gov)\n\nBoth governments nevertheless repeatedly endorsed eventual unity. Fighting in 1972 ended with an Arab League-mediated ceasefire and an agreement to pursue unification, but implementation stalled. Ali Abdullah Saleh became president of the YAR in July 1978; after another interstate war in early 1979, the two heads of state renewed their commitment to union at a meeting in Kuwait that March. A joint draft constitution followed in 1981. Negotiations acquired practical substance in May 1988, when the governments agreed to demilitarize their shared border, permit crossings using national identity cards, and establish a joint oil exploration area along the incompletely demarcated frontier. These measures connected the constitutional project to movement across the border and cooperation over resources. (tile.loc.gov)\n\nOn 22 May 1990, the two states merged to form the Republic of Yemen. Saleh became chairman of a five-member Presidential Council, with YSP secretary-general Ali Salim al-Beidh as deputy chairman; southern president Haydar Abu Bakr al-Attas became prime minister. The council contained three northern and two southern members. A transitional coalition distributed ministerial and deputy-ministerial offices between the former states: where a minister came from one, the deputy generally came from the other. The provisional, 301-member parliament combined 159 members from the northern legislature, 111 from the southern legislature, and 31 presidential appointees. These arrangements preserved representation for both former governments while legislation and administrative structures were being combined. (jiia.or.jp)\n\nThe unity constitution, approved by referendum in May 1991, provided for political association and parliamentary oversight of the executive. Parliament could elect the Presidential Council, withdraw confidence from the government, approve the budget, and question ministers. A political-parties law adopted in 1991 supplied the framework for multiparty competition, replacing the south’s single-party system and the north’s prohibition of formal parties. In the first unified parliamentary election, held in April 1993, Saleh’s General People’s Congress won 123 seats, Islah 62, and the YSP 56. With no party holding a majority, a three-party coalition replaced the original bilateral governing arrangement. (ecoi.net)"

Fighting between military units escalated into civil war in the spring of 1994. On 21 May, Vice-President Ali Salim al-Beidh and other southern leaders proclaimed the Democratic Republic of Yemen, attempting to restore a separate southern state. Forces loyal to President Ali Abdullah Saleh captured Aden on 7 July, ending the secession attempt; leading separatists fled into exile. Saleh’s wartime allies included southern opponents of the Yemeni Socialist Party as well as northern forces, so the military divide did not correspond entirely to the former international boundary. (hrw.org)\n\nAfter the war, the authorities forcibly retired many southern military officers and civil servants and replaced them with northerners. Southern grievances concerned exclusion from public employment and political influence, irregular pension payments, and the allocation of land and oil contracts. In interviews documented by Human Rights Watch, southerners alleged that these assets disproportionately benefited people connected to the presidency. These complaints acquired an organized public expression in 2007, when associations of retired officers began sit-ins and marches demanding reinstatement and improved pensions. The Southern Movement, commonly called al-Hirak, became a loose coalition encompassing civil servants, lawyers, students, party activists and tribal figures. Its demands broadened to employment opportunities, an end to corruption and a larger local share of oil revenues; by 2009, calls for renewed independence were prominent. Human Rights Watch documented arbitrary arrests, restrictions on reporting and unjustified lethal force against protesters, including at least three deaths during an Aden demonstration on 21 May 2009. (hrw.org)\n\nIn the north, Saleh’s government fought six rounds of conflict against the Houthi movement between 2004 and 2010. The movement emerged from a Zaydi religious revival in Saada, where competition over religious education and opposition to government policy intersected with local political grievances. Fighting began in June 2004 when government forces attempted to arrest Hussein Badr al-Din al-Houthi, a former parliamentarian; he was killed that September. His death did not end the insurgency, whose subsequent leadership included his brother Abd al-Malik. Successive campaigns combined government air and artillery attacks with fighting involving rebel forces and local tribal groups. The sixth round began in August 2009, and Saudi Arabia intervened later that year after border clashes. A ceasefire took effect on 12 February 2010. Human Rights Watch reported that just over 265,000 people had been displaced by mid-February, approximately half during the final round; destruction of homes, insecurity and unexploded ordnance impeded return. (carnegie-production-assets.s3.amazonaws.com)\n\nAl-Qaeda’s presence created a separate security challenge. The October 2000 bombing of the USS Cole in Aden killed 17 American sailors. In January 2009, Yemeni and Saudi al-Qaeda elements merged to establish Al-Qaeda in the Arabian Peninsula (AQAP), initially led by Nasir al-Wuhayshi, with Said al-Shihri as his deputy. Its Yemeni predecessor included veterans who had escaped from a Sana’a prison. AQAP organized attacks within Yemen and attempted attacks abroad, giving counterterrorism an increasingly important place in relations between Saleh’s government and the United States. (hrw.org)\n\nCounterterrorism cooperation included specialized Yemeni security units and American targeted strikes. In November 2002, a CIA drone-launched missile killed Qaed Salim Sinan al-Harithi, a suspected organizer of the Cole bombing. Operations subsequently included cruise-missile attacks as well as drone strikes. On 17 December 2009, an American cruise-missile strike at al-Majalah in Abyan killed 14 alleged AQAP members and 41 civilians, according to Human Rights Watch; most of the civilians were women and children. The organization documented the use of cluster submunitions and challenged the operation’s compliance with international law.

Human Rights Watch documented at least 45 deaths and approximately 200 injuries.

The settlement transferred executive authority to Vice-President Abd Rabbuh Mansur Hadi and provided for a national-unity government, an early presidential election and a subsequent constitutional transition. Its immunity provision was implemented through legislation passed on 21 January 2012, protecting Saleh from prosecution and shielding his aides for specified political acts. Hadi stood as the sole consensus candidate in the election of 21 February and was sworn in on 25 February. The transition envisaged national dialogue, constitutional reform and further elections rather than an immediate replacement of the entire political system. (obamawhitehouse.archives.gov)\n\nThe National Dialogue Conference opened on 18 March 2013 under Hadi’s leadership. Its 565 delegates included political parties, Houthi representatives, sections of the Southern Movement, women, youth and civil society. It concluded on 25 January 2014 with an outcome document intended to guide a new constitution and institutional reforms. Agreement on federalism did not resolve the distribution of territory and power: the subsequent proposal for six federal regions remained contested, including by the Houthis. Meanwhile, participation in negotiations did not end armed competition. UN reporting in 2013 recorded Houthi expansion beyond their Saada base into al-Jawf, Amran and Hajjah, with clashes involving government forces, armed Salafists and tribal groups. (osesgy.unmissions.org)\n\nDuring 2014, the Houthi movement, also known as Ansar Allah and led by Abdul-Malik al-Houthi, combined territorial advances with political mobilization. Its forces captured Amran in July. After the government removed fuel subsidies on 30 July, sharply increasing prices, al-Houthi demanded their restoration and the government’s dissolution. Fighting spread into Sana’a in September, and Houthi forces seized key military positions and government buildings by 21 September. The movement presented its actions as a campaign against corruption and political exclusion; presidential representatives accused it of seeking to bring down the government. Separately, the UN Panel of Experts reported testimony that Republican Guard personnel organized by members of Saleh’s family had helped the Houthis capture the capital, despite their previous conflicts with Saleh. (securitycouncilreport.org)\n\nThe Peace and National Partnership Agreement, signed on 21 September 2014, sought to contain the crisis through a new government, economic reforms and implementation of the dialogue outcomes. It did not prevent further coercive action. In January 2015, Houthi forces attacked the presidential compound and placed Hadi and other officials under house arrest; Hadi and the cabinet tendered their resignations. On 6 February, the Houthis announced the dissolution of parliament and new governing arrangements. The UN Security Council rejected this unilateral action in Resolution 2201 of 15 February. Hadi subsequently escaped to Aden and rescinded his resignation. (peacemaker.un.org)\n\nAs Houthi-allied forces advanced southward, Hadi requested external military assistance.

It demanded Houthi withdrawal from seized areas and the relinquishment of weapons taken from military and security institutions, and imposed a targeted arms embargo on designated individuals and entities.

The campaign combined airstrikes with support for Yemeni ground forces and naval restrictions on the country’s ports; the United States initially provided logistical and intelligence support. Saudi Arabia and the United Arab Emirates became the principal coalition powers, but supported increasingly distinct Yemeni partners. The Houthi–Saleh alliance itself broke down in December 2017, when the Houthis killed Saleh following fighting between their forces. (yemen.un.org)\n\nThe war developed several geographically separate fronts rather than a single advancing battle line. Fighting around Taiz divided the city and restricted access routes; the Red Sea coast became another major theatre, particularly around Hodeidah. In 2021, the Houthi offensive against government-held Marib brought combat close to a major concentration of displaced people, while fighting also continued in Hajjah and Taiz. Air warfare extended beyond Yemen: Houthi forces launched ballistic missiles and drones against Saudi Arabia, including attacks directed at Riyadh’s international airport. The UN country team’s 2021 annual report recorded nearly 600 coalition airstrikes per month across Yemen and 340 Houthi missile and drone attacks against Saudi Arabia during that year. (press.un.org)\n\nThe Stockholm Agreement, reached on 13 December 2018 through United Nations mediation under special envoy Martin Griffiths, sought to prevent a further battle for Hodeidah and preserve access through its ports. It comprised an agreement concerning Hodeidah city and the ports of Hodeidah, Salif and Ras Issa, a mechanism for implementing a prisoner-exchange agreement, and an understanding on Taiz. The Hodeidah ceasefire led to the establishment of the United Nations Mission to support the Hudaydah Agreement in January 2019. It was a geographically limited arrangement, not a nationwide cessation of hostilities: fighting on other fronts continued. (un.org)\n\nDivisions within the anti-Houthi camp produced a separate conflict in August 2019, when government troops fought forces of the UAE-backed Southern Transitional Council (STC) in Aden; the UAE conducted airstrikes supporting the STC. The Saudi-brokered Riyadh Agreement, signed on 5 November 2019, attempted to reconcile these rival partners through power-sharing and security-force integration. It required STC forces to be incorporated into the internationally recognized government’s defence and interior ministries. That integration was supposed to occur within 30 days, but Human Rights Watch reported no clear progress by December. The agreement therefore addressed not only relations with the Houthis but also competing chains of command within the coalition-supported camp. (hrw.org)\n\nSpecial envoy Hans Grundberg brokered a nationwide truce beginning on 2 April 2022. Its initial two-month terms required the suspension of offensive ground, air and maritime operations inside Yemen and across its borders, permitted 18 fuel ships to enter Hodeidah’s ports, and provided for two weekly commercial flights between Sana’a and destinations in Jordan and Egypt. It also required talks on opening roads in Taiz and other governorates. Two extensions prolonged the truce until 2 October 2022, when it expired without a renewal agreement. In his subsequent Security Council briefing, Grundberg reported a 60 per cent reduction in casualties during the six months, 56 commercial round-trip flights carrying more than 29,000 passengers, and deliveries exceeding 1.4 million tonnes of fuel. He also reported that the immediate aftermath had not brought a major military escalation. (osesgy.unmissions.org)\n\nCivilian-harm investigations documented abuses by multiple parties. By 5 September 2019, UN human rights personnel had verified 7,508 civilian deaths since 26 March 2015, including 1,997 children; this was a verified count, not a comprehensive estimate of war-related mortality. Human Rights Watch documented at least 90 apparently unlawful coalition airstrikes, alongside indiscriminate Houthi shelling, antipersonnel-mine use and abusive detention by several forces. Investigators examined witness testimony, satellite imagery and weapons remnants; US-origin munitions were identified at more than two dozen attack sites. Arms exports consequently became a legal dispute in the United Kingdom: a June 2019 Court of Appeal ruling required reconsideration of licensing decisions, while the High Court dismissed a later challenge to resumed licensing on 6 June 2023.

Between 2 and 4 January, Saudi-backed Nation’s Shield Forces retook the two governorates with support from Saudi airstrikes, according to ACLED. On 3 January, Presidential Leadership Council chairman Rashad al-Alimi announced the recovery of Hadramawt’s military and security sites; he also discussed the transfer of camps in al-Mahra to Nation’s Shield and local authorities with governor Mohamed Ali Yasser. Saudi-backed forces subsequently took Aden on 7 January. These operations shifted control within the government-aligned coalition rather than constituting an offensive against the Houthis. (acleddata.com)\n\nThe immediate trigger for renewed cross-border escalation was the attack on Sana’a International Airport on 13 July. Yemen’s internationally recognized government said the runway was struck to prevent an Iranian aircraft carrying a Houthi delegation from landing. Houthi military spokesman Yahya Saree attributed the attack to Saudi Arabia, declared the period of de-escalation ended, and announced retaliatory missile and drone attacks on Abha airport. Saudi coalition spokesman Turki al-Malki said air defences had intercepted missiles directed towards southern Saudi Arabia. The parties thus offered different accounts of responsibility and purpose; the Houthi declaration was not a jointly agreed termination of a ceasefire. (apnews.com)\n\nLarge-scale ground fighting resumed in early September around western Taiz and the southern Red Sea coast. By 5 September, nearly 180 fighters had reportedly been killed since clashes began on 3 September. Government counteroffensives extended the fighting into al-Jawf and al-Bayda: on 7 September, al-Alimi claimed advances in those governorates, Taiz and Hodeidah. These were government claims, not independently established changes across all four fronts. Separately, Houthi authorities released footage on 9 September purporting to show attacks against Saudi-backed forces in al-Jawf. Subsequent reporting documented Houthi territorial gains at Mokha and offshore islands, bringing the fighting directly to the Bab al-Mandab Strait. (lemonde.fr)\n\nThe escalation continued into early October. On 4 October, al-Alimi announced a major operation to recover Houthi-held territory as fighting intensified around Taiz. The following day, Yemeni government officials said Saudi-backed forces had retaken several positions around Bab al-Mandab, including Dhubab. The coalition reported extensive air support, while Saree separately claimed missile and drone attacks against Riyadh’s King Khalid airport, a refinery at Rabigh and other Saudi targets. These opposing announcements described different theatres of operations and did not establish an uncontested frontline. Turbah, captured by the Houthis on 4 October, lay on the principal road connecting Taiz with Aden. (apnews.com)\n\nUnited Nations envoy Hans Grundberg warned the Security Council on 10 September that the danger of renewed large-scale conflict had become a reality. Diplomatic contacts nevertheless continued: he met Houthi chief negotiator Mohammed Abdul-Salam in Muscat during the weekend preceding 29 September and held discussions with government and regional representatives in Riyadh. His mediation addressed both the domestic fighting and its regional repercussions. Grundberg stressed that shifting battle lines along the Red Sea threatened commercial maritime routes and that the Yemeni conflict had become increasingly entangled with the wider Middle Eastern wars, including the United States–Israeli war against Iran. (unmissions.org)\n\nBy 6 October 2026, the International Organization for Migration reported that fighting had displaced more than 184,000 people since the beginning of August. Nearly 22,000 were displaced between 27 September and 3 October, with almost 6,500 additional displacements recorded on 4 October alone. Renewed ground offensives, Saudi air operations and Houthi cross-border attacks had therefore displaced the relative military calm maintained after 2022, while negotiations continued alongside combat rather than under a restored, mutually accepted cessation of hostilities.

Ministries and other inherited state institutions operate alongside a supervisory network appointed by the movement’s leadership. These supervisors exercise authority over appointments, administration and revenue collection, sometimes overriding nominal officeholders.

On 9 January 2026, secretary-general Abdulrahman Jalal al-Sebaihi announced its dissolution, but spokesman Anwar al-Tamimi disputed his authority to do so. Southern political positions remained divided: STC supporters invoked self-determination, while the government-aligned Shura Council supported addressing the southern question through a comprehensive political process. (congress.gov)\n\nSaudi Arabia has provided military and political backing to the recognized government, whereas the UAE supported the STC within the wider anti-Houthi camp. Iran supports the Houthis; the US Congressional Research Service records American officials’ assessments that this includes weapons resupply, targeting information and military advice, without equating assistance with Iranian control of the movement. The United States has combined support for UN diplomacy with maritime-security operations, while Oman maintains a mediation channel with Sana’a. On 6 May 2025, Oman announced a US–Houthi agreement under which neither side would target the other, including American vessels in the Red Sea and Bab al-Mandab. (congress.gov)\n\nInternational sanctions distinguish between named individuals and the movement as an entity. Security Council Resolution 2140 (2014) established targeted asset freezes and travel bans; Resolution 2216 (2015) added a targeted arms embargo. In February 2022, the Houthis themselves were listed as subject to that embargo. Resolution 2801, adopted on 14 November 2025, renewed the financial and travel measures until 14 November 2026. Separately, the United States designated Ansar Allah a Specially Designated Global Terrorist effective 16 February 2024 and announced its Foreign Terrorist Organization designation on 4 March 2025. US sanctions retain specified humanitarian authorizations. The United Kingdom implements targeted financial, immigration and military-trade restrictions through its Yemen sanctions regulations.

      "text": "The March 2026 Humanitarian Needs and Response Plan, issued by the United Nations, estimated that 22.3 million people in Yemen required humanitarian assistance and protection. It identified 18.3 million people as acutely food insecure and sought US$2.16 billion to reach 12 million people, with 9.4 million prioritized according to the severity of their needs. Conflict, disrupted livelihoods, deteriorating public services and reduced humanitarian funding had compounded the emergency. The plan described communities experiencing catastrophic food insecurity, but household-level “Catastrophe” in the Integrated Food Security Phase Classification (IPC) is distinct from an area-level declaration of famine, which requires evidence concerning food deprivation, acute malnutrition and mortality. (yemen.un.org)\n\nChild malnutrition remained a major source of illness and vulnerability. The 2026 plan estimated that more than 2.2 million children under five were acutely malnourished, including approximately 516,000 with severe acute malnutrition; another 1.3 million pregnant and breastfeeding women were expected to be malnourished. Only 59.3% of health facilities were fully functional, and complete vaccination coverage stood at 63%. The World Health Organization (WHO) reported continuing cholera, malaria, dengue and vaccine-preventable disease outbreaks. Reduced access to routine treatment and nutrition services left malnourished children particularly vulnerable to life-threatening infections, while insecurity and funding shortages constrained both primary health care and hospital services. (yemen.un.org)\n\nCholera illustrates the interaction between damaged water systems and weakened medical provision. WHO reported 249,900 suspected cases and 861 associated deaths between 1 January and 1 December 2024. Its response combined outbreak investigation, laboratory testing, treatment supplies and an oral vaccination campaign reaching 3.2 million people in 34 districts across six governorates. Nevertheless, a US$20 million funding gap for the October 2024–March 2025 response threatened treatment capacity. Between March and the end of November 2024, lack of funding had already closed 47 diarrhoea treatment centres and 234 oral rehydration centres. In February 2026, WHO appealed for US$38.8 million for emergency health operations; this was its agency-specific requirement, rather than the budget for Yemen’s entire humanitarian health response. (yemen.un.org)\n\nUNHCR placed the number of internally displaced people at 5.2 million in 2026. Many families had spent years in informal settlements with limited prospects for return or integration, and some had experienced repeated displacement. Although some displaced people returned, access restrictions and protection risks persisted; floods had also become a major driver of new displacement. The September 2026 escalation produced additional flight within Yemen and across the sea. On 15 September, the Associated Press reported that more than 2,000 Yemenis were in Djibouti receiving food and shelter from the government and the International Organization for Migration (IOM). Fuel shortages impeded further boat crossings, while reception facilities faced constraints on water, shelter and other services. (unhcr.org)\n\nPopulation movements also ran in the opposite direction: predominantly Ethiopian and, to a lesser extent, Somali migrants travelled through Djibouti or Somalia, crossed to Yemen and attempted to continue towards Saudi Arabia and other Gulf states. Yemen therefore remained both a country of displacement and a migration transit country. IOM’s voluntary humanitarian return programme provided stranded migrants with an assisted route home to Ethiopia or Somalia, including counselling, protection assessments, family tracing, consular coordination, medical screening and post-arrival support. These assisted returns were distinct from spontaneous sea journeys and forced returns along the regional migration corridor. (crisisresponse.iom.int)\n\nAid delivery was further restricted by staff detentions and interference with humanitarian premises. On 19 January 2026, UN humanitarian coordinator Julien Harneis reported that 73 UN colleagues had been detained in successive episodes since 2021, and that detentions and office seizures had severely constrained operations in Houthi-controlled areas. The UN had suspended official movements into and within those areas following further detentions in January 2025. Harneis subsequently reported that, on 29 January 2026, Houthi authorities removed telecommunications equipment and vehicles from at least six unstaffed UN offices in Sana’a without authorization. Such restrictions affected organizations already reducing programmes because of funding shortages, including support for essential health services. (yemen.un.org)"

      "heading": "Economy, currency and aid dependence",
      "text": "Before the war, oil and natural gas exports supplied much of Yemen’s foreign exchange and public revenue, although services and agriculture employed considerably more people. Oil accounted for more than 60 percent of fiscal revenue; declining production made the budget increasingly dependent on international prices. Output peaked at about 457,000 barrels per day in 2002 and fell by more than 65 percent over the following decade. Liquefied natural gas provided an additional revenue stream: the government’s share of export earnings from the Yemen LNG project reached approximately US$665 million in 2014. War, infrastructure damage and interrupted production subsequently reduced hydrocarbon receipts. Houthi attacks on export facilities halted the internationally recognized government’s oil exports in late 2022; the World Bank reported that exports remained blocked in May 2026. (worldbank.org)\n\nThe division of the Central Bank of Yemen created separate monetary systems. The transfer of its headquarters to Aden in 2016 left a competing institution operating in Sana’a. In December 2019, the Sana’a authorities prohibited newer rial banknotes issued by the Aden bank, effectively separating the circulation of old and new notes and producing different exchange rates for the same nominal currency. In government-controlled areas, financing budget deficits through central-bank credit increased liquidity, while lost oil earnings reduced foreign-exchange supplies. The Aden market rate weakened from approximately 1,540 rials per US dollar to 2,065 during 2024, reached 2,905 in July 2025, and recovered to 1,676 by early August following stabilization measures. These dated quotations describe the southern market, not a nationwide exchange rate. (documents1.worldbank.org)\n\nImport dependence transmits currency depreciation and international price increases directly into household costs. Yemen imports approximately 90 percent of its food, and remittances, aid and bilateral financial support have become important substitutes for lost export earnings. (yemen.un.org) According to the International Monetary Fund, Saudi Arabia supplied approximately US$2 billion in financial support during 2023–24. Saudi deposits enabled the Aden central bank to sell foreign exchange, helping finance imports and absorb rials created through government borrowing. Fuel assistance operates through a different mechanism: it supplies diesel and heavy fuel oil for electricity generation, reducing the government’s fuel-purchase burden. Saudi grants included US$422 million in 2021 and US$200 million in 2022. Humanitarian financing nevertheless declined: the World Bank reported that the 2025 UN response plan received only 28 percent of its requirements, compared with 56.5 percent in 2024. (imf.org)\n\nQat cultivation links commercial agriculture to widespread domestic consumption. Farmers, traders and retailers derive income from its regular sale, but production competes with food crops and agricultural exports for land and scarce water. Historical World Bank estimates illustrate its economic importance: in 2007, qat represented approximately 6 percent of GDP, 10 percent of consumption and one-third of agricultural GDP, and supported employment for one in seven working Yemenis. These are pre-war estimates rather than measurements of its present share. Qat’s role as a cash crop therefore combines substantial rural earnings with pressure on resources and household expenditure. (blogs.worldbank.org)\n\nThe informal economy was already dominant before large-scale warfare. The 2013–14 labour-force survey recorded informal-sector employment at 73.2 percent, with services accounting for 55.6 percent of employment, agriculture 29.2 percent and industry 14.5 percent. Unemployment was 13.5 percent overall, 24.5 percent among young people and 26.1 percent among women; labour-force participation was only 36.3 percent. These survey figures should not be treated as current wartime rates. (ilo.org) In May 2026, the World Bank estimated that nearly three-quarters of the population lived below the poverty line. Its national estimates showed real GDP contracting by 1.5 percent in 2025, while reduced grants and fiscal resources constrained salary payments, subsidies and essential public spending.

      "heading": "Red Sea, Bab al-Mandab and strategic geography",
      "text": "The Bab al-Mandab strait connects the Gulf of Aden and Arabian Sea to the Red Sea, forming the southern gateway to the Suez Canal route between Asia and Europe. Approximately 29 kilometres wide at its narrowest point, it concentrates commercial shipping near Yemen’s coast. Most Persian Gulf oil and natural gas shipments travelling through Suez or Egypt’s SUMED pipeline also pass through Bab al-Mandab. Disruption therefore affects a connected maritime corridor rather than an isolated passage: ships avoiding the strait generally also bypass Suez, taking the longer route around Africa’s Cape of Good Hope. Yemen’s strategic importance derives from its proximity to these shipping lanes, not simply from the volume of its own exports. (eia.gov)\n\nThe Red Sea crisis developed from the regional conflict beginning in October 2023; attacks on commercial shipping expanded in November. The Houthis presented their campaign as pressure on Israel over the war in Gaza, although vessels attacked included ships with little or no connection to Israel. Their methods included anti-ship missiles, drones and the seizure of vessels: the vehicle carrier Galaxy Leader was captured on 19 November 2023. (apnews.com) Shipping companies responded by suspending Red Sea services or rerouting vessels. In February 2024, UN Trade and Development reported that Suez transits had fallen 42% from their peak and weekly container-ship transits by 67%. Shanghai–Europe container spot freight rates had risen 256% since early December. Longer voyages increased fuel consumption, delayed deliveries and absorbed shipping capacity, transmitting disruption into freight costs and potential consumer-price pressures. (unctad.org)\n\nEnergy cargoes underwent a substantial geographical redistribution. The US Energy Information Administration, using Vortexa tracking data, estimated that oil flows through Bab al-Mandab averaged 4.0 million barrels per day during January–August 2024, compared with 8.7 million in the full year 2023. Over the same comparison periods, oil flows around the Cape of Good Hope increased from 6.0 million to 9.2 million barrels per day. These figures measure diversion of cargoes rather than an equivalent loss of global oil supply. The immediate economic mechanism was longer, more expensive transportation; changes in freight and delivered energy costs should therefore be distinguished from changes in crude-oil benchmark prices. (eia.gov)\n\nMilitary installations on Yemen’s islands provide positions beside the strait and its eastern approaches. In May 2021, satellite imagery showed a 1.85-kilometre runway and three hangars on Mayun, also called Perim. Yemeni officials attributed construction to the United Arab Emirates, while the Saudi-led coalition acknowledged a presence and stated that equipment there was under coalition command. (euronews.com) Farther east, the UAE deployed troops to Socotra in 2018; satellite imagery reported in April 2024 also documented runway construction on Abd al-Kuri in the Socotra archipelago. The UAE described its Socotra presence as humanitarian, illustrating the need to distinguish documented infrastructure from disputed claims about its ownership or purpose. (apnews.com) Naval protection constituted a separate response: US Defense Secretary Lloyd Austin announced Operation Prosperity Guardian on 18 December 2023 under the Combined Maritime Forces’ Task Force 153. The European Union launched Operation Aspides on 19 February 2024 with a defensive mandate to accompany vessels and protect them against attacks at sea. (defense.gov)\n\nThe Gulf of Aden had previously become a major international naval operating area because of Somalia-based piracy, which threatened shipping during the late 2000s and early 2010s. Unlike the later Houthi campaign, these hijackings principally sought ransom for vessels and crews. (imo.org) On 2 June 2008, the UN Security Council adopted Resolution 1816, authorizing cooperating states, with Somalia’s transitional government’s consent, to enter Somali territorial waters and repress piracy for an initial six months. The authorization was specific to Somalia and did not create a general right to intervene in other states’ territorial seas. (press.un.org) EU Operation Atalanta began on 8 December 2008, protecting vulnerable shipping and World Food Programme deliveries while deterring and disrupting pirate operations. Its counter-piracy function was distinct from the missile-and-drone protection mission later assigned to Aspides. (eeas.europa.eu)"

      "heading": "Culture, architecture and daily life",
      "text": "The Old City of Sana’a, inscribed on the UNESCO World Heritage List in 1986, is distinguished by multistorey houses with stone ground floors, upper structures of burnt brick or rammed earth, and white gypsum ornament outlining windows and geometric brickwork. Its dense residential quarters incorporate mosques, bathhouses, markets and cultivated gardens, rather than separating monuments from everyday habitation. Shibam, inscribed in 1982, represents a different tradition of architecture: its predominantly sixteenth-century, sun-dried mud-brick houses rise as high as seven storeys within a fortified, approximately rectangular street plan. Their vertical construction accommodated households within a defensible enclosure, while the surrounding irrigated landscape supplied both food and building materials. (whc.unesco.org)\n\nArmed conflict has damaged this inhabited cultural heritage. On 2 July 2015, UNESCO placed both Sana’a and Shibam on the List of World Heritage in Danger. In Sana’a, it documented particularly serious destruction in the al-Qasimi neighbourhood, damage to the twelfth-century al-Mahdi Mosque and surrounding houses, and widespread breakage of decorated doors and window panes. Shibam’s listing reflected its vulnerability amid conflict, rather than an equivalent record of bombardment. Its earthen buildings also face deterioration associated with flooding, inadequate drainage and interrupted maintenance: introduced piped water, without adequate disposal systems, can undermine the conservation of structures built with traditional materials. (unesco.org)\n\nAfternoon gatherings around qat connect domestic space with social life, particularly in the northern highlands. Participants chew tender leaves and retain them in one cheek during sessions that may continue for several hours; conversation encompasses personal news, employment, business and public affairs. The mafraj, often an upper reception room in a traditional house, provides space for receiving guests and gathering with relatives or friends. Sessions are commonly gender-separated, and women’s afternoon gatherings, often called tafriṭa, have their own patterns of visiting, dress and refreshments. Such gatherings are not simply recreational: they maintain relationships and circulate information, although separation can exclude women from business discussions conducted in male groups. (qat-yemen.com)\n\nPoetry and music are closely integrated with these occasions. The Song of Sana’a, or al-ghināʾ al-ṣanʿānī, draws on poetic traditions dating to the fourteenth century and accompanies afternoon gatherings and samra wedding evenings. UNESCO proclaimed it a masterpiece of oral and intangible heritage in 2003 and inscribed it on the Representative List of Intangible Cultural Heritage in 2008. A solo singer traditionally performs with a qanbus, a Yemeni lute, and a sahn nuhasi, a copper tray balanced on the player’s thumbs and struck with the fingers. In tribal settings, improvised verse also conveys congratulations, criticism and proposals for reconciliation. Anthropologist Steven C. Caton’s fieldwork in Khawlan al-Tiyal, begun in 1979, documented poetry’s role in weddings and dispute mediation; his study appeared as “Peaks of Yemen I Summon” in 1990. (ich.unesco.org)\n\nHospitality and family relationships are expressed through reciprocal visits, wedding attendance and exchanges between hosts and guests. In northern and eastern communities, groups arriving at weddings may perform zamil verses praising their hosts, who respond with welcoming poetry. Another cultural marker is the jambiya, a short, curved dagger worn at the front of an embroidered belt, especially in northern male dress; its workmanship can communicate prestige and family standing. A Sana’a example dated to the 1930s–1940s in the British Museum combines a steel blade with a wooden sheath encased in silver, gilded decoration, filigree and a woven belt, illustrating the multiple crafts involved in its production. (yementimes.com)\n\nDiaspora activities sustain these traditions through performance, publishing and food culture. Liverpool Arab Arts Festival’s Yemen in Conflict project organized writing workshops between 2019 and 2021; the resulting anthology, Tomorrow Will Shine, brought together work by 20 Yemeni poets, edited by Hamdan Dammag, Taher Qassim and Deryn Rees-Jones. Yemeni-owned cafés in the United States provide another setting for cultural transmission, serving drinks such as qishr, made from dried coffee-cherry husks, and spiced Adeni tea. Their interiors, menus and evening social use adapt elements of Yemeni hospitality to diaspora settings and introduce them to customers beyond Yemeni communities. (arabartsfestival.com)"

      "heading": "Education, science and research",
      "text": "School participation has been disrupted by conflict, displacement and the loss of household income. Yemen’s Central Statistical Organization, supported by UNICEF, surveyed approximately 20,000 households between July 2022 and May 2023. The resulting Multiple Indicator Cluster Survey found that 25% of children of basic-school age and 53% of those of upper-secondary-school age were out of school; only half of children of school-entry age were enrolled in the first primary grade. Completion rates were 53% for basic education and 37% for upper secondary education. UNICEF’s September 2025 report Building Futures estimated that 3.7 million children aged 5–17 were out of school in 2024. Physical damage, schools’ use for non-educational purposes and overcrowding have reduced available classroom space, while displacement repeatedly interrupts attendance. (unicef.org)\n\nInterrupted teacher salaries have also reduced teaching time and increased families’ educational costs. UNICEF’s 2025 report identified more than 193,000 teachers—65% of the total—as affected by non-payment of monthly salaries since 2016. Teachers have sought other employment, and some schools have collected contributions from pupils to continue operating. In March 2019, UNICEF launched monthly incentives equivalent to US$50, aiming to reach more than 136,000 teachers and school-based staff in over 10,300 schools. These payments supported continued attendance by teachers but were not a restoration of the public salary system. Girls face additional barriers associated with distant schools, insecurity, shortages of female teachers and inadequate sanitation facilities. (unicef.org)\n\nThe gender gap in literacy predates the war. UNESCO Institute for Statistics estimates for 2015 placed literacy among people aged 15 and above at 70.2% overall, 85.5% for men and 55.1% for women. Among those aged 15–24, the corresponding estimates were 97.6% for males and 82.8% for females, indicating a narrower gap in the younger generation. These historical estimates describe accumulated educational attainment rather than present-day learning conditions. The 2022–2023 household survey provides a more recent basis for examining school participation and disparities, but its measures should not be treated as interchangeable with earlier adult-literacy estimates. (uis.unesco.org)\n\nPublic higher education developed around institutions including Sana’a University, established in 1970, and Aden University, whose precursor College of Education opened in 1970 and whose legal establishment followed on September 10, 1975. Conflict has constrained both enrollment and academic work. Fahmi Khaled’s 2024 Sana’a Center study, drawing on interviews in four governorates, reported that Sana’a University’s Arabic Department had 26 students across four years in 2023, compared with more than 300 in 2014. Interviewees described unpaid salaries, unaffordable transport and publication costs, and the loss of funding for international conferences. Travel constraints also restricted postgraduate study abroad. These institutional examples are not a national enrollment series: the study relied partly on staff estimates because comprehensive published statistics were unavailable. (su.edu.ye)\n\nScientific research is limited by access to equipment, literature, funding and international networks. The 2015 UNESCO Science Report recorded that a proposed science, technology and innovation observatory, for which Yemen requested assistance in 2014, had stalled amid escalating conflict. Archaeological research has continued through documentation and cooperation even where excavation is suspended. The German Archaeological Institute’s Yemen expedition began in 1978; its Sana’a branch has investigated Marib and Sirwah and works with antiquities authorities on the AYDA digital monument register. This combines research documentation with monitoring of endangered sites and illicit antiquities trafficking. The institute reports that its field projects in Yemen are suspended because of the political situation, while training exchanges continue. Consequently, archaeological analysis remains dependent in part on earlier excavation records and archives, without the systematic new field observations needed to resolve all outstanding questions.
