Shu Han
221–263 CE
Overview
Southwestern Three Kingdoms state in Sichuan (capital Chengdu), founded by Liu Bei claiming Han legitimacy; famed for chancellor Zhuge Liang's northern campaigns. Conquered by Cao Wei in 263.
Shu Han (House of Liu)
Shu Han (221-263 CE) was the southwestern state of the Three Kingdoms, founded by Liu Bei at Chengdu after Cao Pi's usurpation of the Eastern Han. It called itself simply Han and claimed to be the legitimate continuation of the dynasty through Liu Bei's descent from the imperial house, preserving Han institutional forms in the Sichuan basin. The costly defeat at Yiling in 222 and Liu Bei's death in 223 left the teenage Liu Shan under the regency of Chancellor Zhuge Liang, who suppressed the Nanzhong revolt in 225 and then launched repeated northern expeditions against Cao Wei from Hanzhong until his death in 234. Under Jiang Wan and Fei Yi the state turned defensive; Jiang Wei resumed fruitless northern probes after 253. Weakest of the three states in population and resources, Shu fell in 263 when Deng Ai crossed the mountains by the Yinping road and forced Liu Shan's surrender, clearing the way for the Western Jin reunification.
Territory Phases
Shu Han — Founding under Liu Bei221 CE – 223 CE
Liu Bei proclaimed himself emperor of a restored Han at Chengdu in May 221 CE (era Zhangwu) in response to Cao Pi's usurpation of the Eastern Han, appointing Zhuge Liang as Chancellor. The state inherited Liu Zhang's Yi Province intact — the Sichuan basin, the Nanzhong commanderies to the south, and Hanzhong, taken from Cao Cao in 219. Jing Province had already been lost to Sun Quan in 219, so the eastern campaign launched in 221 was a failed reconquest rather than the loss of standing territory; it ended in defeat at Yiling in 222.
Shu Han — Nanzhong Revolt and Regency223 CE – 225 CE
Liu Bei died at Baidicheng (Yong'an) in 223 after the ruinous defeat at Yiling, leaving the teenage Liu Shan under Zhuge Liang's regency. News of his death triggered a revolt across Nanzhong: Yong Kai in Yizhou commandery, Gao Ding in Yuexi and Zhu Bao in Zangke threw off Shu authority, with Eastern Wu backing Yong Kai. Effective control contracted to the Sichuan basin and Hanzhong while Zhuge Liang rebuilt the army and renewed the Wu alliance. Yongchang, the westernmost commandery, held out for Shu throughout under Lü Kai and Wang Kang.
Shu Han — Southern Consolidation225 CE – 228 CE
Zhuge Liang marched south in 225 CE and broke the revolt, defeating Gao Ding and Zhu Bao and campaigning as far as Lake Dian; Yong Kai was killed by his own side. Administrative supremacy over Nanzhong was restored and the region reorganised, supplying troops and material for the northern campaigns that followed. Control remained uneven and worked through local leaders rather than direct rule, so the extent reflects administrative claim rather than uniform government.
Shu Han — Northern Expeditions228 CE – 234 CE
With the south secured, Zhuge Liang launched repeated offensives against Cao Wei through the Qinling passes from his Hanzhong base between 228 and 234 CE. Deep penetrations toward Longyou and the Wei valley were temporary, but in 229 Chen Shi captured the Wudu and Yinping commanderies, which were retained as durable territory on the northern frontier. Zhuge Liang died on campaign at the Wuzhang Plains in 234, ending the most vigorous phase of the restoration effort.
Shu Han — Defensive Era under Jiang Wan and Fei Yi234 CE – 253 CE
Jiang Wan and then Fei Yi succeeded Zhuge Liang as chief minister and turned Shu away from sustained offensives toward consolidation, economic recovery and the alliance with Eastern Wu. The realm held its full extent — the Sichuan basin, Hanzhong, Nanzhong and the Wudu-Yinping frontier — with only limited frontier activity. Fei Yi in particular restrained Jiang Wei's appetite for northern campaigns, keeping expeditions small until his assassination in 253 CE.
Shu Han — Jiang Wei Ascendant253 CE – 263 CE
After Fei Yi's assassination in 253 CE, Jiang Wei's military influence expanded and he resumed large northern probes into Wei's Longyou frontier. They achieved nothing durable and drained a state a fraction of Wei's size, while at court the eunuch Huang Hao gained influence over Liu Shan. Territory was unchanged until the Wei invasion of 263 CE: Zhong Hui broke through in the north while Deng Ai crossed the mountains by the Yinping road, bypassed the Jianmen Pass and defeated Zhuge Zhan at Mianzhu, forcing Liu Shan's surrender at Chengdu.
Key Rulers
Liu Bei (劉備; courtesy name Xuande 玄德; Emperor Zhaolie 昭烈皇帝; temple name Liezu 烈祖; 'First Ruler' Xianzhu 先主)
221 CE – 223 CE
★★★
Founder of Shu Han. A warlord of claimed Han imperial descent who took Yi Province from Liu Zhang in 214 and Hanzhong from Cao Cao in 219, he proclaimed himself emperor of a restored Han at Chengdu in May 221 after Cao Pi deposed Emperor Xian, adopting the era name Zhangwu and appointing Zhuge Liang as Chancellor. His invasion east to avenge Guan Yu and recover Jing Province — already lost to Sun Quan in 219 — was destroyed by Lu Xun at Yiling in 222. He died at Baidicheng in 223, entrusting Liu Shan and the state to Zhuge Liang.
Liu Shan (劉禪; courtesy name Gongsi 公嗣; 'Later Ruler' Houzhu 後主; Duke Si of Anle 安樂思公 under Jin)
223 CE – 263 CE
★★
Second and last emperor of Shu Han, on the throne for forty years — longer than any other ruler of the Three Kingdoms. He acceded as a teenager under Zhuge Liang's regency and afterwards under Jiang Wan and Fei Yi, exercising little independent authority; in his later years the eunuch Huang Hao gained influence at court. He surrendered to Deng Ai outside Chengdu in the eleventh lunar month of 263 and lived out his life at Luoyang. Posthumously made Duke Si of Anle under Jin, and honoured as Emperor Xiaohuai (孝懷皇帝) by the Han-Zhao state around 304.
Zhuge Liang (諸葛亮; courtesy name Kongming 孔明; Marquis Wu of Zhongwu 忠武侯)
223 CE – 234 CE
★★★
Chancellor of Shu Han and effective head of state through Liu Shan's minority and beyond. Appointed Chancellor at the founding in 221 and entrusted with the realm by the dying Liu Bei in 223, he restored the alliance with Eastern Wu, suppressed the Nanzhong revolt in 225, and from 228 launched five northern expeditions against Cao Wei through the Qinling passes. He died on campaign at the Wuzhang Plains in 234. His administrative rigour and the Chushi Biao memorials made him the defining figure of the state and, later, the central character of its literary afterlife.
Jiang Wan (蔣琬; courtesy name Gongyan 公琰)
234 CE – 243 CE
★★
Zhuge Liang's designated successor as chief minister. He abandoned sustained offensives through the Qinling in favour of consolidation and economic recovery, considering and then dropping a riverine strategy down the Han river against Wei. His tenure marks the shift from restoration campaigns to the defensive posture that held for the rest of the state's existence. Failing health forced him to hand the offices of General-in-Chief and Manager of the Affairs of the Masters of Writing to Fei Yi in late 243; he lived on in a reduced role until his death in 246, so his active tenure is 234-243 rather than 234-246.
Fei Yi (費禕; courtesy name Wenwei 文偉)
243 CE – 253 CE
★★
Chief minister after Jiang Wan and the last of the ministers appointed in Zhuge Liang's line. He took over the offices of General-in-Chief and Manager of the Affairs of the Masters of Writing in late 243, when the ailing Jiang Wan ceded them three years before his death. He continued the defensive policy and deliberately restrained Jiang Wei, capping the forces released for northern operations so that expeditions stayed small. He moved his headquarters forward to Hanshou in 251 and was assassinated there at a New Year banquet in 253 by Guo Xiu, a defector from Wei, after which Jiang Wei's influence over Shu strategy grew unchecked.
Jiang Wei (姜維; courtesy name Boyue 伯約)
253 CE – 263 CE
★★
A Wei officer from Tianshui who defected to Zhuge Liang during the first northern expedition in 228 and rose to command Shu's armies. Freed by Fei Yi's death in 253 to pursue his mentor's strategy at scale, he launched repeated campaigns into Wei's Longyou frontier that won no durable ground and exhausted a state already far smaller than its rival. He held the Jianmen Pass against Zhong Hui in 263 but was outflanked by Deng Ai's march over the Yinping road, and died the following year in a failed attempt to restore Shu by turning Zhong Hui against Wei.
Key Events
Proclamation of Han by Liu Bei at Chengdu221 CE
In May 221 CE, months after Cao Pi compelled Emperor Xian's abdication and founded Wei, Liu Bei accepted the imperial title at Chengdu, declaring the Han dynasty continued rather than ended. He took the era name Zhangwu and appointed Zhuge Liang as Chancellor. The state never called itself Shu — that name comes from the region and from later historiography, which needed to distinguish it from the Han it claimed to be. Encoded as 'inscription' following the convention used for the accession edicts of Cao Wei and the Xin.
Battle of Yiling (Xiaoting)222 CE
Liu Bei's campaign east through the Three Gorges to punish Sun Quan for the killing of Guan Yu and to recover Jing Province — lost to Wu in 219, so a reconquest attempt rather than the defence of standing territory — was destroyed by Lu Xun near modern Yichang. The Wu commander held his position for months before firing the Shu camps strung out along the gorges. The army was wrecked and the survivors fell back to Baidicheng; Shu never again campaigned eastward, and the defeat fixed its strategic horizon on the north for the remaining forty years.
Death of Liu Bei at Baidicheng and accession of Liu Shan223 CE
Liu Bei died of illness at Baidicheng (Yong'an, modern Fengjie) in 223, having never returned to Chengdu after Yiling. He entrusted his heir and the state to Zhuge Liang in a famous deathbed audience. The teenage Liu Shan succeeded under Zhuge Liang's regency, beginning a forty-year reign in which the Chancellor and his successors, rather than the emperor, directed policy.
Revolt of Nanzhong223 CE
News of Liu Bei's death set off a revolt across the southern commanderies. Yong Kai killed the administrator of Yizhou and accepted appointment from Eastern Wu; Gao Ding rose in Yuexi and Zhu Bao in Zangke. Shu's effective control contracted to the Sichuan basin and Hanzhong for two years while Zhuge Liang rebuilt the army. Yongchang, the westernmost commandery, did not fall: Lü Kai and Wang Kang refused Yong Kai entry and held it in isolation until relief came.
Restoration of the alliance with Eastern Wu223 CE
Zhuge Liang sent Deng Zhi to Sun Quan to repair the alliance that Guan Yu's death and the Yiling campaign had destroyed. Wu broke with Wei and resumed cooperation with Shu, and the understanding held for the remaining forty years of both states — the strategic precondition for every northern expedition Shu afterwards attempted, since it freed the eastern frontier at Baidicheng.
Zhuge Liang's Southern Campaign225 CE
Zhuge Liang marched into Nanzhong in three columns in 225, defeating Gao Ding and Zhu Bao and reaching Lake Dian; Yong Kai was killed by his own side during the campaign. Administrative supremacy was restored and the commanderies reorganised, giving Shu the southern manpower and material its northern campaigns then consumed. Government continued to work through local leaders rather than direct rule. The traditional account of the 'seven captures and releases' of Meng Huo is a later elaboration whose literal accuracy is disputed.
The Chushi Biao (Memorial on Dispatching the Army)227 CE
Before moving his army to Hanzhong to open the northern campaigns, Zhuge Liang submitted a memorial to Liu Shan setting out the case for the expeditions, naming the officials the young emperor should trust, and recalling Liu Bei's charge to him. Preserved in the Sanguozhi, it became one of the most widely read prose texts in the Chinese tradition and the principal statement of what the state understood itself to be for.
Battle of Jieting and the first Northern Expedition228 CE
The first northern expedition opened with three Longyou commanderies defecting to Shu, but Ma Su, given the vanguard over more experienced officers, camped on high ground away from water at Jieting and was cut off and routed by Zhang He. Zhuge Liang withdrew, executed Ma Su and demoted himself three ranks. The reverse ended Shu's only realistic chance of taking and holding Longyou.
Capture of Wudu and Yinping229 CE
Shu forces under Chen Shi took the mountain commanderies of Wudu and Yinping on the Gansu border. Unlike the deeper penetrations toward Longyou and the Wei valley, these were held: they remained Shu territory until the end and were the one durable territorial gain of the northern expeditions. The Yinping road they secured was the route Deng Ai used against Shu in 263.
Death of Zhuge Liang at the Wuzhang Plains234 CE
On his fifth and largest northern expedition Zhuge Liang crossed the Qinling to the Wuzhang Plains south of the Wei river and settled in to farm alongside the local population, having solved the supply problem that ended earlier campaigns. Sima Yi refused battle. Zhuge Liang fell ill and died in camp after a hundred-day standoff, and the army withdrew intact. Jiang Wan succeeded him as chief minister; no later Shu leader again threatened the Wei heartland.
Assassination of Fei Yi at Hanshou253 CE
On 16 February 253, at a New Year banquet at Hanshou, the chief minister Fei Yi was stabbed to death by Guo Xiu, an officer who had surrendered from Wei and been kept in Shu service. Fei Yi had been the brake on Jiang Wei's northern ambitions, releasing only small forces to him; with him gone, Jiang Wei's influence over strategy grew and the large, futile campaigns of the 250s followed.
Conquest of Shu Han by Cao Wei263 CE
Sima Zhao launched a three-army invasion in 263. Jiang Wei fell back and held the Jianmen Pass against Zhong Hui's main force, but Deng Ai took a small army over some three hundred li of unroaded mountain by the Yinping route, emerged behind the defences, and destroyed Zhuge Zhan's scratch army at Mianzhu. With the passes bypassed and the capital exposed, Liu Shan surrendered outside Chengdu in the eleventh lunar month. Huo Yi was still administering Nanzhong when the order to submit reached him, and the Yong'an garrison under Luo Xian went over to Wei and then held the town against an Eastern Wu attempt to take it.
