Liu Bang

Liu Bang (traditionally c. 256–195 BCE), posthumously known as Emperor Gaozu of Han, founded the Han dynasty and reigned from 202 to 195 BCE. Born in Pei County in the state of Chu, he started as a minor local functionary and rose to become a leader of the uprisings that brought down the Qin dynasty. After a prolonged struggle with Xiang Yu known as the Chu–Han Contest, he established a unified empire with its capital at Chang'an. His career is one of the best-documented rises from humble origins in early Chinese history, and his life is recorded mainly in the Shiji of Sima Qian and in the Book of Han.

His importance lies less in personal conquest than in the state he built. Liu Bang kept the centralized administrative structure inherited from Qin while softening its harsh legal and penal practices, and he worked to restore an economy devastated by years of war. He also dealt with the problem of semi-autonomous kingdoms, eliminating many of the non-Liu rulers he had enfeoffed, and he faced the Xiongnu confederation on the northern frontier, where he accepted a costly peace arrangement. The Han model of government and the long dynastic tradition that followed shaped Chinese statecraft for centuries, and the later name for the Han people is derived from the dynasty.

This entry follows his life in chronological order, from his origins and the uprisings against Qin, through the Chu–Han war and his enthronement, to his domestic policies, foreign relations, and death. It then examines the sources on his life, including the problems of legend and bias in the historical record, and concludes with his lasting reputation and the modern archaeological evidence that has helped revise traditional accounts.

Origins and early life

Birth, names and family

Reference works give Liu Bang's birth year as either 256 or 247 BCE. In either the 51st year of King Zhaoxiang of Qin (256 BCE) or the 3rd year of King Zhuangxiang of Qin (247 BCE), during the Warring States Period, Liu Bang was born in Zhongyangli, Pei Fengyi. His birthplace is usually given as Pei County, which was then part of the conquered state of Chu. The naming is also unsettled. Some sources record Liu Ji (劉季) as his birth name, while other reference works list Ji (季) as his courtesy name, so the two forms overlap in the record. His parents go unnamed in the early accounts. They were simply referred to as "Liu Taigong" (Old Sir Liu) and "Liu Ao" (Old Madam Liu). Later compilations assign them personal names, but these are not found in the early narratives. Liu is also counted among the few founders of Chinese dynasties who emerged from the peasant class.

Early career as a minor official

Liu's first public post was a low-ranking one in Pei. He initially entered the Qin dynasty bureaucracy as a minor law enforcement officer in his hometown in Pei County. Accounts differ on his exact rank. One source describes him as a patrol officer at Sishui village, a settlement in Pei County. He was then a patrol officer in the village. Another calls him a Tingzhang, like a police inspector, of Sishui Ting, Peixian county.

His duties were largely penal and labour-related. In about 210 BCE he was assigned to escort a group of laborers in chains to Mount Li near Xianyang, where the First Qin Emperor was building his mausoleum. The journey went wrong. Liu Bang released some prisoners he was escorting to Mount Li to be labourers, and became a fugitive. He then hid with followers on Mount Mangdang, where he kept in contact with associates in Pei. The Qin penal system could be harsh toward minor officials. In one episode involving his friend Xiahou Ying, under the law of the Qin dynasty at the time, Liu Bang would be punished more severely than a civilian because he was an officeholder, albeit a low-ranking one.

Local networks and supporters

Liu's early career is recorded through a circle of Pei associates, some of whom later became his key followers. Xiao He, who served as a gongcao (magistrate's secretary) in the administrative office of Pei County, was well versed in law and had a wide network of friends and acquaintances, among whom include Liu Bang, Cao Shen, Fan Kuai, Xiahou Ying and Zhou Bo. Cao Shen served as a prison warden in his early days. Xiahou Ying would visit his friend Liu Bang, then a patrol officer in the village, and spend a long time chatting with him. The early narratives present these men as the local elite who backed him when the Qin collapsed. In 209 BCE, the people agreed to decide their leader by luck, and Xiao He's lottery placed Liu at the head of the rising. The details of that uprising belong to the next section.

Birth legends and signs of destiny

Accounts of Liu's birth were shaped by later propaganda. When Liu Bang became emperor, legendary tales about his origins were created, so as to provide legitimacy to his rule. The best-known story has his mother caught in a storm and sheltering under a bridge. The sky darkened, and lightning struck. When her husband came to her, he saw a dragon beside her. Liu Bang is said to have been conceived shortly after this supernatural incident. A variant has her conceiving after a dream. Physical marks were added to the story. Liu was said to have had a high nose, complete with whiskers and a striking beard, and others would observe that his distinct features had some resemblance to that of a dragon. He was also said to have 72 dark spots all over his left leg.

The dragon motif linked him to imperial symbolism. The Chinese dragon was associated with the emperor of China and used as a symbol to represent imperial power. Later genealogical claims extended this. In imperial Han myth, Liu Bang was a descendant of the mythical Emperor Yao, who descended from the Yellow Emperor. Liu's red banner and his association with the Red Emperor were part of the same effort, since due to the earlier legend of him being the son of the Red Emperor, he revered the color red. Early sources also describe him as an unpromising youth, which sits uneasily with these omens. His father reportedly often called him a "little rascal" for his lazy lifestyle.

Rebellion against Qin

The 209 BCE uprisings and Liu Bang's entry into the revolt

The revolt that drew Liu Bang in began in 209 BCE, when Chen Sheng and Wu Guang raised a rising at Dazexiang in present-day Anhui. Qin forces under Zhang Han suppressed it within about five months, but other rebellions erupted consecutively over the next three years, and Liu Bang's movement was one of them. Liu was a minor Qin functionary from Pei County, and his entry into the rebellion followed the local pattern: the county magistrate briefly considered joining the rebels himself, then reversed course. Liu's supporters, Xiao He and Cao Shen, had urged the magistrate to recall him, and when the magistrate changed his mind and denied Liu Bang's party entry into the city, Liu's letters shot over the walls persuaded the townspeople to kill the magistrate and open the gates. In the traditional account, the Pei townsfolk then chose him as leader, and he took the title Duke of Pei (沛公), a title that marked him as the head of a regional force rather than a claimant to a larger realm.

Alignment with the Chu royal house

Liu's group did not act alone. He first attached himself to the rebel army of Xiang Liang, whose nephew Xiang Yu was his most important rival. King Huai II was effectively a puppet ruler because the power of Chu was concentrated in Xiang Liang's hands. After Xiang Liang was killed at Dingtao in 208 BCE, the restored Chu king regained some control over the armies and issued the arrangement that defined the race for the Qin heartland. He ordered Song Yi and Liu Bang to lead separate armies against Qin, and promised to award the title "King of Guanzhong" to whoever entered Guanzhong (the Qin heartland) first. Xiang Yu was placed under Song Yi as second-in-command, but he killed Song Yi and took over the army, and the king reluctantly confirmed the change. Liu was thus free to move west while Xiang Yu was fighting in the east.

The race for Guanzhong

Liu's western march was therefore a contest against the Chu commanders as well as against Qin. Xiang Yu was delayed by the campaign against Zhang Han, which gave Liu room to act. Liu conquered Wu Pass and became the first rebel to invade the Guanzhong region. He then used a mix of diplomacy, bribery and surprise attacks. Zhang Liang, a strategist who had joined him, suggested bribing a Qin commander at Yao Pass into surrender. Liu also posted troops at Hangu Pass to stop Xiang Yu, but Xiang Yu broke through and pushed on. The meeting between the two camps was defused by Xiang Bo, Xiang Yu's uncle, who had a friendship with Zhang Liang. Xiang Bo argued that Liu Bang had rendered great service by capturing Xianyang and that attacking him would be an unjust act. Xiang Yu accepted this argument for the moment.

Xianyang and the surrender of Ziying

The date of Liu's arrival at the Qin capital is given differently in the sources. One source places it in late 207, while others date the surrender of the last Qin ruler, Ziying, to 206 BCE, and the two dates are often combined. Ziying, who had earlier plotted against the eunuch Zhao Gao, decided to surrender the capital, which ended the dynasty in practice. Liu's conduct on entering Xianyang became the basis of his claim to Guanzhong. He reportedly prohibited his troops from harming the population or looting the city, and publicly proclaimed that all harsh Qin laws were to be abolished except strict punishments for murder, harm and theft. The account of Xiao He saving the state documents from the chancellor's office shows that practical administration was also part of the picture, even as Liu's men seized treasure in the palace.

Liu's position at Xianyang was thus strong, but it was also precarious. Xiang Yu's partition of the empire in early 206 BCE assigned Guanzhong to three surrendered Qin generals and gave Liu the remote territories of Hanzhong, Ba and Shu, which set the stage for the Chu–Han Contention that followed.

The Chu–Han Contest

Partition and the Hanzhong settlement

After the Qin collapsed, Xiang Yu became the most powerful rebel commander and reorganized the former empire on his own authority. He divided the former Qin Empire into the Eighteen Kingdoms and styled himself Hegemon-King of Western Chu. Liu Bang had expected the Guanzhong heartland around the Qin capital, but that area was split into three, each of which was given to a former Qin general. Instead Liu Bang was made King of Han, the area to the south of Qin. He withdrew to Bashu, the region of present-day Sichuan and Chongqing, along with 30,000 troops and thousands of civilians. To convince Xiang Yu that he did not intend to return east, Liu had the gallery roads into Bashu destroyed (in order to trick Xiang Yu into believing that he had no intention of leaving Bashu). His forces later passed through Chencang secretly, and this route became the base for the campaign to retake the Guanzhong basin.

The Hongmen banquet and the breakdown of trust

Relations between the two men soured soon after Liu entered Xianyang. The Hongmen banquet, dated to 206 BCE and set near Xinfeng outside Xi'an, is recorded as an attempt to kill Liu Bang (Motive: to assassinate Liu Bang). According to the tradition, a Han officer, Cao Wushang, reported that Liu wanted to rule within the Pass, and Xiang Yu's counsellor Fan Zeng read Liu's restraint toward wealth and women as a sign of ambition. At the feast, Fan Zeng repeatedly gave King Xiang meaningful looks and, three times, raised the jade pendant he wore to show him. Xiang Yu hesitated. Fan Zeng then had Xiang Zhuang perform a sword dance and find an opportunity to assassinate Liu Bang. Xiang Bo, Xiang Yu's uncle and a friend of Zhang Liang, suddenly stood up and joined the dance. Whenever Xiang Zhuang thrust his sword at Liu Bang, Xiang Bo parried his blow or stood in between the two. Liu escaped, and later granted him the imperial family name "Liu", and enfeoffed him as the Marquis of Yeyang. The episode is known mainly from Sima Qian's narrative, originating from "Records of the Grand Historian: Annals of Xiang Yu", and its dialogue and motives should be read as literary shaping rather than a verified record.

Campaigns, alliances, and Han Xin

In 205 BCE Liu mustered an army of about 560,000 with support from the kings who surrendered to him. In the eighth lunar month, the Chu capital, Pengcheng, fell to a coalition force led by Liu Bang. Xiang Yu then returned with a much smaller force. The Han forces were unprepared and suffered heavy losses. Liu's family was captured and held as hostages (Liu Bang's family members were captured by Chu forces and kept as hostages.), and his strength fell sharply.

In 204 BCE Xiang Yu besieged Liu at Xingyang, close to the Ao granary, and once again Liu Bang was forced to escape at the head of a handful of men. A long stalemate followed, as Xiang Yu's army was short of supplies.

Liu's success in the north depended largely on Han Xin. Han Xin won a major victory at the battle of the Wei River, and in 203 was made king of Qi as a reward. Before that, Han Xin had conquered the State of Wei in the summer of 205 and moved against Dai. Defections also weakened Xiang Yu: Ying Bu, the King of Jiujiang, defected to Liu Bang. Deception played a part too. Xiang Yu dismissed Fan Zeng after falling for Chen Ping's ruse. Likewise, Xiang Yu also fell for a ruse by Chen Ping, one of Liu Bang's advisers, and started doubting Zhongli's loyalty, which drove Zhongli to leave him.

At one point Xiang Yu tried to end the war by offering Han Xin a three-way division of China, but Han Xin chose to remain loyal to Liu Bang. His adviser Kuai Tong had urged acceptance, predicting that Liu Bang would eventually execute Han Xin as being too dangerous.

Gaixia and the death of Xiang Yu

An earlier attempt at partition had already failed. In 203 BCE the two sides agreed to split China, but Liu Bang had almost immediately broken the agreement and turned on Xiang Yu. By late 203, Xiang Yu's position had become desperate. He held a fortified camp at Gaixia with 100,000 men in his fortified camp at Gaixia, but food was running short. His enemies apparently had 500,000 men. Sources differ on the exact date: one gives December 203 BC while another gives January 202 BC, and the battle is commonly placed in 202 BCE.

Within the camp, the story of Lady Yu, Xiang Yu's consort, became central to later accounts. She killed herself with his sword, and Xiang Yu buried Lady Yu, erecting a large mound over her grave. Popular retellings add that Han Xin had kidnapped Xiang Yu's beloved consort to draw Xiang Yu out, a detail that is not secure.

Xiang Yu's retreat was a steady collapse. By the time he crossed the Huai River only 100 were left, and by the time the Han caught up with him near the Wu River that had dropped to 28. Accounts of his final skirmishes are often considered exaggerated (greatly exaggerated in the ancient sources). Xiang Yu claimed that his loss was Heaven's will. He killed himself near the river, and his body was dismembered as Lu Matong and other Han soldiers fought to claim the body. The city of Lu then held out until Liu Bang arrived with Xiang Yu's head, and then surrendered. A few months later Liu Bang declared himself to be Emperor, founding the Han Dynasty.

Founding the Han state

Liu Bang's formal accession came in the second month of 202 BCE, when he took the imperial title at Dingtao. Sources place the ceremony on the north bank of the Fan River, though some give the Si River. The site was symbolic rather than a seat of power: the realm was still held together by alliances, and the title was offered by his confederates after the defeat of Xiang Yu. He first made Luoyang his base, then moved the court to Chang'an, the former Qin region near the old capital at Xianyang. The first palace, Changle, was built across the river from the Qin ruins, and the Weiyang Palace followed in 200 BCE. Chang'an became the imperial capital for most of the Western Han period, and its founding is traditionally treated as the origin of the city that is now Xi'an.

The early Han state combined two systems of local rule. Commanderies administered directly by the central court coexisted with kingdoms ruled by enfeoffed princes, and the kingdoms were initially the more prestigious of the two. Liu Bang's reasoning was partly drawn from his reading of Qin's collapse, which he attributed to the failure to enfeoff members of the ruling house as a buffer around the throne. The result was a division of the empire in which the western heartland was governed by the court's own officials while much of the populous east was held by kings. This arrangement gave kings the tax revenues of their territories, a fact that the court would later find to be a structural problem.

The dynasty's rulers therefore moved to reshape the kingdoms. Liu Bang had initially enfeoffed a number of non-Liu kings during the war, among them Han Xin, Peng Yue, Ying Bu, Zang Tu, Zhang Ao and Xin of Han, many of them former rivals or commanders who had built their own power bases. Over the following years he removed most of them, through execution, forced suicide, or flight. Han Xin was executed in 196 BCE, and Peng Yue was put to death for alleged treason. Ying Bu's rebellion in 196 BCE led to a campaign in which the emperor himself was wounded. The stated aim was to centralize authority, and the court replaced the eliminated kings with members of the Liu clan. Nine Liu princes were enfeoffed on the former territories, and a covenant was said to have been sworn with ministers that only Liu princes would hold kingdoms. This "no kings except those of the Liu family" oath was broken after the emperor's death, when Empress Lü installed her own relatives as kings, which shows how far the principle depended on the individual ruler.

Legitimacy was another concern. Early Han thinkers placed the dynasty within the Five Powers cycle, which held that Han was in the phase of Water and therefore revered black, as the Qin had done. The court also developed formal ceremonies for an imperial court that had been shaped by the rough habits of the army, a process traditionally associated with the scholar Shusun Tong around 200 BCE. Earlier Qin sacrificial sites and state cults were largely kept in use, which suggested continuity with the old order as well as a new dynastic claim. The Han court's dependence on these rituals, and on the principle of a single surname for the throne, became part of how later dynasties understood the founding of the Han.

Taken together, these measures show Liu Bang's dual priority: a unified state that could be held by one lineage, and an administrative model that tolerated semi-autonomous kingdoms in the east. Later rulers would revisit the balance between the two, but the framework set in these years, with its commanderies, kings, and Liu-clan oath, defined the political structure of the Western Han.

Domestic governance and economic recovery

Liu Bang's first legal gesture came when he entered the Qin heartland in 206 BCE. He declared the harsh Qin penal regime invalid and promised a more just penal law. The promise took years to carry out. The short set of wartime rules he had relied on proved too thin to restrain crime, and the work of drafting a lasting code went to Chancellor Xiao He. According to the Book of Han, Xiao He drew on the Qin statutes, kept the provisions he judged suitable for the times, and compiled the Statutes in Nine Chapters (Statutes in Nine Chapters). The code survives only in fragments. Later accounts say he added further chapters to the Qin base, including one on household registration.

The relationship to Qin law was therefore one of selective continuity rather than rupture. Bamboo-slip texts from Shuihudi and Zhangjiashan show that much of the early Han code was derived from Qin statutes, a finding that sits uneasily with the Han historians' image of Qin as a uniquely brutal regime. Early Han punishments, including mutilating penalties, also carried over from Qin practice. The civil side of the legal order was more developed than the simplified rhetoric suggests. Household statutes dealt with land holdings, registration, household division, land transactions, and inheritance, and the state treated these as matters for ordinary legal procedure. Historians still debate how much of this system Liu Bang designed himself and how much was inherited, and the surviving evidence rarely settles the question.

Fiscal policy was driven by necessity. The state granaries were largely empty, and the government collected little revenue after years of war. Liu Bang set the field tax at one-fifteenth of the harvest, although other accounts put the Qin norm at one-fifteenth and the Han rate at one-thirtieth, so the sources conflict on the exact figures. Labour service was cut to a more tolerable level. Those who had sold themselves into bondage during the war were restored to commoner status, and demobilized soldiers received ranks and priority in claiming land and housing. Troops were assigned land to reclaim and cultivate. Displaced people were allowed to re-register as households in their new places. At the same time, the court reaffirmed the principle of favouring agriculture over commerce, and one account says the poll tax on merchants was doubled.

Population recovery was the central aim of these measures. Many peasants had abandoned their homes and wandered in search of food, so resettlement and the restoration of registered households were the priority. Private landholding, in which land could be bought and sold, continued from the Qin period. State investment in water conservancy was meant to support farming, and the policy of light taxation and light corvée is generally credited to Liu Bang, though the phrase "rest and recuperation" that later described the Wen and Jing reigns was not his own. The same leniency had a cost: low taxes and weak state intervention allowed local magnates to expand their holdings, a problem that would grow in later decades.

Liu Bang governed through a combination of Qin-style centralized administration and a network of trusted associates. Xiao He served as chancellor until his death, and the founders' inner circle included Cao Shen, Chen Ping, and Zhou Bo. Their philosophical outlook was pragmatic rather than doctrinaire. The early court favoured the Huang-Lao approach, which stressed non-interference and the danger of excessive punishment, and Liu Bang's reign is associated with simplified laws and reduced expenditure. Ideas drawn from Confucianism and Legalism remained present in administration, and the later thinker Jia Yi argued that ritual should guide governance while law should not be neglected. Whether this mix reflected a deliberate statecraft or the pressures of the moment is a question that the sources leave open.

Reconstruction of cities and infrastructure is less well documented for Liu Bang's own reign than for his successors. The evidence chiefly concerns agricultural recovery, land distribution, and the management of revenue, and these were the foundations on which the later Han state, including its tax system and its legal institutions, was built.

Relations with the Xiongnu and other neighbors

The Xiongnu threat and the defeat at Baideng

The most serious external problem facing the new state was the Xiongnu confederation on the northern steppe. Qin had sent a large expedition against these nomads, but the campaign backfired: Modu Chanyu (or Maodun) took power and reorganised the clans, making them a more serious threat. The collapse of Qin then gave the Xiongnu room to consolidate further. The chaos that followed the fall of Qin created a power vacuum and let the Xiongnu unite under Modu Chanyu into a powerful nomadic confederacy.

Liu Bang himself led a campaign against the Xiongnu, and it ended in humiliation. The Han army was caught near Pingcheng, at Mount Baideng (present-day Datong, Shanxi), and was hemmed in and besieged for seven days before it could break free. Accounts differ on how the siege was lifted. One source credits trickery or bribery (probably involving Modu Chanyu's wife). The Book of Han preserves a version in which ten envoys to the Xiongnu reported that they were weak and easily defeated, while Lou Jing alone surmised that the nomads were hiding their strength to lure the Chinese into an ambush. The emperor jailed Lou Jing in anger, and later regretted it. Some modern narratives describe the event differently, so the exact sequence remains uncertain.

After Baideng, Liu Bang abandoned a military solution to the Xiongnu threat. The strategic weakness was clear: the state was still recovering from the Chu–Han war, and its chariot forces were poorly suited to fighting mounted archers. The threat did not end with the defeat. Around 201 BCE, the Han king of Hán, Han Xin, was moved to a frontier post to guard against the Xiongnu, and after the nomads attacked Mayi, Liu Bang suspected Han Xin was secretly conspiring with the Xiongnu against him. Han Xin subsequently defected to the Xiongnu. In 197 and 196 BCE, Xiongnu raids on Dai Commandery were reportedly aided by Han Xin.

The heqin agreement of 198 BCE

The policy adopted instead was the heqin or "peace marriage" arrangement. The courtier Lou Jing proposed it, and proposed granting the eldest daughter of Emperor Gaozu of Han to Modu Chanyu of the Xiongnu. The treaty was concluded in 198 BCE. Its terms, as recorded in later sources, combined a royal marriage, regular gifts, and a formal border. Those terms included a Han princess given in marriage to the shanyu; periodic gifts of silk, liquor and rice to the Xiongnu; equal status between the states; and the Great Wall as mutual border. The Xiongnu also reportedly asked for Empress Lü, and in 192 B.C.E., Modu even asked for the hand of the widowed Empress Lü.

The arrangement was nominally one of equals, but it was in practice a flow of goods from Han to the steppe. The heqin agreement nominally held the leaders of the Xiongnu and the Han as equal partners in a royal marriage alliance, but the Han were forced to send large amounts of tribute items such as silk clothes, food, and wine to the Xiongnu. The bride was not always an imperial daughter. The Han court sent random unrelated commoner women falsely labeled as "princesses" and members of the Han imperial family multiple times, which limited the cost to the imperial house. The treaty was renewed many times, and up to 135 B.C.E., the treaty was renewed no less than nine times, with an increase of "gifts" with each subsequent agreement. Its value for the Chinese side was limited: while the Xiongnu benefited from the marriage treaties, from the Chinese perspective they were costly and ineffective. Raids also continued during the treaty period.

Nanyue and the southern frontier

To the south, the kingdom of Nanyue was a different kind of problem. Its founder, Zhao Tuo, was a former Qin officer who established the independent kingdom of Nanyue with its capital in Panyu (now Guangzhou) in 204 BC. At first Liu Bang accepted a formal arrangement. Upon the establishment of the Han dynasty, Zhao initially accepted a position similar to its other kings, recognizing Liu Bang's nominal authority in exchange for good relations and autonomy. In 196 BCE, the emperor sent the envoy Lu Jia to confirm this recognition. Lu Jia succeeded by reminding Zhao of the balance of power, pointing out the vast disparity in strength between Nanyue and the Han dynasty.

The relationship deteriorated under Empress Lü. Zhao resented the ban on exports of metal goods and female livestock to Nanyue. In 183 BC, he proclaimed himself the "Martial Emperor of the Southern Yue", which implied a perceived status on equal footing with the Han emperor. Dates vary between sources, and some give 185 BCE. A punitive expedition in 181 BCE failed, because the heat and dampness caused many of his officers and men to fall ill, and he failed to make it across the mountains into enemy territory. In 180 BCE, Lu Jia returned and succeeded in convincing Zhao Tuo to give up on his title as emperor and pay homage to Han as a nominal vassal.

Strategic weakness or deliberate statecraft?

Historians disagree about how to read these arrangements. The first view emphasizes weakness. Han had few resources for a large war, and heqin bought time while the state recovered. Such a reading fits the Han court's own explanation, that the empire was not yet strong enough to confront the Xiongnu. A second view stresses purpose. One analysis argues that this was not, however, the only objective of the original heqin treaty. The marriage was also meant to bind the Xiongnu leadership politically: the hope was that a Chinese princess would have a son who would become Chanyu and who would owe allegiance to China.

Contemporary criticism reflected both pragmatic and ideological positions. Chao Cuo opposed the heqin agreement for practical reasons rather than Jia Yi's staunch ideological position that superior sedentary Chinese culture should dominate over the northern nomads. The treaty survived these objections for decades, and the court under Emperor Wen returned to it even after serious disputes. Whether the heqin system is best understood as a costly concession or as a considered attempt at control remains an open question in scholarship.

Final years and death

Liu Bang's last years were shaped by the need to control the allies who had helped him win the empire. After 202 BC he had enfeoffed several non-Liu commanders as kings, and these large, semi-autonomous states collected taxes, kept armies, and held major cities. Within a few years they looked like a threat to the court. Liu Bang reduced them one by one. Some kings were demoted, others were executed for rebellion, and the list of those removed includes Han Xin, Peng Yue, Zang Tu, and Ying Bu. The sources also describe a "White Horse Oath," sworn with his closest followers, that any non-Liu man who made himself king should be attacked by the rest. Whether the oath is historical is uncertain, but later writers used it to explain the policy.

The last of these conflicts was the revolt of Ying Bu. He had first served Xiang Yu, then defected to Liu Bang and was made King of Huainan in 203 BC. Accounts differ on the date of his rebellion, which is given as 196 BC in some sources and 195 BC in others. Liu Bang was already ill when he led the campaign in person. During the fighting he was struck by a stray arrow. The wound worsened, and he withdrew to his inner chambers for a long time, where his health continued to decline. Ying Bu was defeated and killed, but the campaign marked the end of Liu Bang's active rule.

The succession dispute

Liu Bang's health crisis came at the same time as a dispute over the succession. He preferred Liu Ruyi, the son of his favorite consort Lady Qi, to his designated heir, Liu Ying, the son of Empress Lü. Liu Ying was not the eldest son, but his mother was the empress, and this gave him the stronger claim. Liu Bang tried several times to replace him, but officials, including Shusun Tong, opposed the change. Liu Ying's position was secured when a group of reclusive scholars, the "Four Hoary Men of Mount Shang," appeared at court in support of the heir. According to the traditional account, Liu Bang then concluded that the heir had powerful backing and that the dispute could not be resolved in favor of Ruyi. The episode shows how much Liu Bang's final decisions depended on the court's elite and on the empress's position.

Death and burial

Liu Bang died on 1 June 195 BC at the Changle Palace in Chang'an. Sources report that Empress Lü brought in a physician, but he refused treatment. On his deathbed he placed the government in the hands of Xiao He, Chen Ping, and Zhou Bo, the men who would later be central to the suppression of the Lü family. He was buried at the Changling mausoleum in Xianyang. The tomb followed the Qin model of a large earthen mound, though on a smaller scale, and Empress Lü was later buried in an adjacent tomb. Liu Ying, posthumously known as Emperor Hui, succeeded him at about fifteen years old, and the court was run from the start by his mother.

Empress Lü and the consequences

Empress Lü used her position to remove her rivals. Consort Qi was arrested and treated as a convict after Liu Bang's death, and her son Liu Ruyi was summoned to the capital. Lü's power grew throughout Emperor Hui's reign (195–188 BC). When the emperor died without a designated heir, the empress dowager adopted two of his sons, who were the nominal rulers, and her relatives held the highest offices. Lü, who was regent until her death in 180 BC, placed her clansmen in key posts. After her death, the Lü family was driven from power and exterminated, and Liu Ying's half-brother, Liu Heng, became Emperor Wen. The episode, known as the Lü Clan Disturbance, showed that the founding settlement of Liu Bang's empire, with its mix of Liu princes and powerful non-royal officials, could still be disrupted by the imperial household itself.

Historical sources, legend, and image

The Shiji and its portrait

Most of what survives about Liu Bang comes from the Shiji (史记), which Sima Qian finished in the early 90s BCE. Sima Qian spent much of the subsequent decade authoring and compiling the Shiji and completed it before 91 BC, probably around 94 BC. Its structure became the template for later official histories. The Shiji set the model for all subsequent dynastic histories of China.

Sima Qian builds Liu Bang's character mainly through speech. In The Basic Annals of Gaozu, when portraying the character of Liu Bang, Sima Qian frequently employed the method of language description. Through highly individualized dialogue, he vividly presented Liu Bang's image to the reader. The most quoted self-assessment comes in a passage where Liu Bang says he cannot match Zhang Liang at strategy or Xiao He in governing the state, comforting the people, ensuring supply provisions, and keeping the supply routes open.

The portrait is mixed rather than hagiographic. Modern readers note that in Sima Qian's portrait of Liu Bang, we read both about his personal obnoxiousness and also about his modesty and willingness to give credit to others. Sima Qian also records Liu Bang's public denunciation of Xiang Yu's misconduct, and some scholars see in the two biographies a deliberate effort to show both men's flaws. He acknowledges Liu Bang's ability to unite talented people and his concern for the people, while also noting his cunning and ruthlessness. The decision to grant Xiang Yu an imperial-style annals, although he never became emperor, is often read as evidence that Sima Qian was not simply writing a Han panegyric. This circumstance shows that historiography can also be truthful, but it also shows that Sima Qian did probably not favour Liu Bang as a person.

The Book of Han and later revisions

The Book of Han (汉书), compiled mainly by Ban Gu in the late first century CE and completed by his family and associates, rewrote the earlier material on the founder. Its treatment of the Gaozu annals generally follows the Shiji closely, but it adjusts the tone toward a more orthodox account of Han legitimacy and drops or softens some of the sharper episodes. (This summary draws on general scholarly knowledge rather than the sources consulted for this entry.) Textual transmission added further variation: until the work was transferred to paper many centuries later, circulation would have been difficult and piecemeal, which accounts for many of the errors and variations in the text.

Legend: the white snake and the Red Emperor

The founding legend is recorded in the Shiji. When Liu Bang was serving as a village head, he passed through a marsh, where he encountered a large white snake blocking his way. Liu drew his sword and cut the snake in half. A weeping old woman then appeared and claimed that the snake was the son of the White Emperor, and it had just been killed by the son of the Red Emperor, who had passed by. Later retellings move the episode to a convict escort and to a night when Liu was drunk, and they present the story as a prophecy made after he became an outlaw. The story was helped along by a prophecy (made after he became an outlaw, which is totally not suspicious timing).

The episode works within the Five Phases theory. Qin Shihuang considered himself to be the "water virtue" (Qin favored black), while Liu Bang regarded himself as the "son of the Red Emperor" (fire virtue, favored red), which secretly conformed to the logic of dynasty succession of "fire overcoming water". The red banner he raised and the cloud-qi omens reported by Lü Zhi belong to the same campaign of self-presentation. Liu Bang then complied with the popular will, set up an altar, erected a red banner, and, due to the earlier legend of him being the son of the Red Emperor, revered the color red.

The verse attributed to him, usually called "Song of the Great Wind" (大风歌), is recorded in the Shiji and tied to a visit to his home region. It is traditionally read as an expression of anxiety about finding capable men to guard the realm. Its authenticity and original context are debated, and modern historians use it mainly to study how his image was shaped, not as direct evidence of his thought.

Bamboo-slip legal texts

The most important recent evidence for early Han law is archaeological. In 1983, over a thousand Western Han early-period wooden slips, including ancient legal texts such as "Han Lü" (Han Laws), were discovered in three Han tombs at Zhangjiashan in Jiangling, Hubei. The legal material comes chiefly from tomb 247. The early-Han legal texts excavated from tomb number 247 at Zhangjiashan in Jiangling, Hubei province, received immediate attention in western scholarship. The collection includes the statutes and ordinances of the second year of the Han, and its case records include earlier precedents. Although its date roughly corresponds with the tomb occupant's death, one of the legal cases discussed in the work on law was dated 246 BC, with some even older legal precedents of the State of Qin mixed in. The most recent legal case in that work was dated 196 BC.

These texts complicate the Shiji's picture of a clean break with Qin. Some statutes closely match a Qin text recovered from Shuihudi, suggesting continuity in legal drafting. For modern assessments of Liu Bang's promise of simple laws, the slips are therefore a counterweight to the narrative in the historical record, showing a code that was far more elaborate than the founding rhetoric implied.

Legacy and historiography

The Han as a model dynasty

The Han was one of the longest-lived imperial houses in Chinese history. It lasted about 400 years, counting the Wang Mang interregnum, and its two phases are usually divided by the capital's move from Chang'an to Luoyang. The earlier phase, with its capital at Chang'an, is called the Former or Western Han (206 BCE–25 CE), and the later phase is called the Later or Eastern Han (25–220 CE). Every emperor of the dynasty came from the Liu lineage, which is why the name Liu is so closely tied to the Han period.

From the fifth century onward, Chinese writers treated the Han as a benchmark for political order and cultural achievement. Its bureaucracy was associated with the adoption of Confucianism as the state ideology and with a bureaucracy based on merit, although the extent and timing of that change are debated. Modern comparisons also place Han China alongside Rome: it was comparable with the contemporary Roman Empire in population size, geographical extent, and cultural reach. The model of a unified, centralized empire that the Han supposedly embodied was therefore one that later dynasties could invoke, imitate, or criticize.

The name "Han"

Liu Bang's dynastic title took its name from a territory he had been given before he became emperor. When Xiang Yu assigned him the former Qin territories of Hanzhong, Ba and Shu, which he would rule as the king of Han, the title became the basis of the dynasty's name. The name later spread to the people and the writing system. The term "Han people" first appeared during the Northern and Southern period and was inspired by the Han dynasty, and the dynasty name is also used for Chinese characters, known as hanzi, which connects the dynasty to the script itself.

The modern sense of "Han" as an ethnic label developed much later, and its meaning shifted with political circumstances. After the fall of the Qing, many Han Chinese looked back to the time of Emperor Gaozu, the name Liu Bang took after coming to power, to find a supposedly purer era of Chinese civilization. In this way, a title that Liu Bang received in 206 BCE acquired a political and national meaning in the twentieth century. For details on ethnic terminology, see Han Chinese.

Liu Bang in literature, drama, and popular culture

In traditional storytelling, Liu Bang is often a secondary figure, while Xiang Yu holds the tragic center. The best-known example is the Peking opera Farewell My Concubine, which pits King Xiang Yu against the rebel warrior who created the Han Dynasty, Liu Bang. In the play, Liu's troops sing songs from Xiang's homeland to show that Chu has already fallen, and Xiang's favorite concubine dies after a sword dance. Such works present Liu as the victor who drives the drama forward but does not command the audience's sympathy in the same way. The opera tradition in general draws heavily on the history of this period, and it remains one of the main ways many Chinese audiences encounter the story; see Chinese opera.

Liu Bang has also been the subject of historical television. The 1998 series Han Liu Bang starred Liu Wenzhi as the titular character, with thirty-five episodes, and was first broadcast on CCTV in China in 1998. Its existence shows that the founder continues to serve as a source of national narrative, though the series reflects the approach of its own era rather than early sources.

Xiang Yu and the comparison

Modern assessments often contrast the two men by social background. Xiang Yu was a nobleman whose family had long served Chu, while Liu Bang represented the common people. Scholars also note the sharp difference in temperament: one account describes Xiang as a patrician warrior in the older aristocratic style, while Liu is presented as an opportunist who relied on the advice of talented subordinates.

The traditional record gives Xiang Yu a special place. Sima Qian treated him in the Shiji with the dignity of a ruler, while Ban Gu's Han shu later recast him in a biographical form. This choice reflects how Han historians framed the fall of Qin and the rise of the Liu house as a legitimate transfer of rule. Modern historians have questioned how far this framing is accurate. Liu's advantages included the grain-rich Guanzhong region and the appeal to local populations: Han Xin argued that the people of Guanzhong would welcome Liu Bang as their king because they despised Xiang Yu for his brutality. Accounts of Xiang's brutality, including the looting of Xianyang, may therefore have been shaped in part by the victors' interest in portraying the contest as moral as well as military.

Continuities between Qin and Han

Whether the Han represented a break from Qin or an inheritance of it remains a central question. The Han publicly condemned Qin's harsh laws and brief reign, and Liu Bang's pledge in Xianyang to replace severe punishments with simple rules is often cited as evidence of this rejection. Yet the Han retained much of Qin's administrative structure, including commanderies and counties, and its early statutes drew on Qin legal traditions. Recent discoveries of bamboo-slip legal texts have strengthened the view that continuity was substantial; see Bamboo and Wooden Slips and Legalism. Scholars therefore tend to see the transition as a combination of political reset and institutional inheritance, rather than a clean rupture.
