Shu Han (蜀汉) was the western kingdom of the Three Kingdoms period. Liu Bei declared himself emperor in 221, claiming legitimacy as a descendant of the Han imperial house and intent on restoring the Han. The state lasted until 263, when Wei (by then under the Sima family) conquered it.
Foundation
Liu Bei built his power through the late Han and warlord period with the help of Zhuge Liang, Guan Yu, Zhang Fei, and others. After taking Yi Province from Liu Zhang in 214 and surviving the Battle of Yiling against Eastern Wu in 222, he ruled from Chengdu.
In 221, following the abdication of Emperor Xian and the establishment of Cao Wei, Liu Bei declared himself Emperor of Han, claiming legitimacy as a descendant of the Han imperial house. His reign title was Zhangwu (章武), and he was posthumously honoured as Emperor Zhaolie (昭烈皇帝).
Territory and administration
Shu Han controlled primarily Yi Province (益州), corresponding to modern Sichuan, Chongqing, and parts of southern Gansu and Shaanxi. The region was mountainous and naturally defensible, with the Qinling Mountains protecting the north and the Three Gorges protecting the east.
Key territories:
- Chengdu Plain , Agricultural heartland, well-irrigated by the Dujiangyan system
- Hanzhong Commandery , Strategic northern gateway, conquered from Cao Cao in 219
- Nanzhong , Southern regions (modern Yunnan and Guizhou), pacified by Zhuge Liang’s southern campaign (225)
Administrative structure:
- Yi Province was divided into approximately 22 commanderies
- Each commandery was governed by a Grand Administrator (太守)
- Central government followed Han precedents, with Zhuge Liang serving as Chancellor (丞相)

Economy
Shu Han’s economy was based on agriculture, salt production, and textile manufacturing. The Chengdu Plain was highly productive, with the Dujiangyan irrigation system ensuring stable harvests.
Key economic resources:
- Salt wells , Major source of state revenue, particularly in Ziliujing (modern Zigong)
- Brocade production , Chengdu brocade (蜀锦) was a luxury export and diplomatic gift
- Iron mining , Used for weapons and agricultural tools
- Lacquerware , Craft production for domestic use and trade
Currency:
- Shu Han issued Zhibai currency (直百钱), a large bronze coin nominally worth 100 regular coins
- This debased currency helped fund military campaigns but caused inflation
Trade:
- Limited trade with Wei due to ongoing conflict
- Some trade with Wu via the Yangtze River
- Southern trade with Nanzhong and beyond (modern Southeast Asia)
Culture
Shu Han positioned itself as the legitimate successor to the Han dynasty, maintaining Han court rituals and administrative practices.
Notable cultural aspects:
- Confucian governance , Zhuge Liang emphasised meritocracy and legalist administration
- Historical records , Chen Shou, a Shu official, later wrote the Records of the Three Kingdoms
- Poetry and literature , Zhuge Liang’s Chu Shi Biao (出師表, “Memorial on Deploying the Army”) became a classic
Legacy
Shu Han is remembered as the righteous kingdom in Chinese culture, largely due to the Romance of the Three Kingdoms, which portrays Liu Bei and Zhuge Liang as heroic figures struggling against overwhelming odds.
Historical impact:
- First of the three kingdoms to fall (263)
- Zhuge Liang’s governance became a model for later Chinese administrators
- The kingdom’s story inspired countless works of literature, drama, and art
Modern legacy:
- Chengdu remains a major city in Sichuan Province
- Zhuge Liang’s temple (Wuhou Shrine) in Chengdu is a popular tourist destination
- Shu Han is often romanticised in popular culture as the “underdog” kingdom
Fall
In 263, Wei (effectively under the Sima clan) sent Deng Ai and Zhong Hui to invade. Jiang Wei held the passes at Jianmen, but Deng Ai led a daring mountain crossing and reached Chengdu unexpectedly.
Liu Shan, advised by the minister Qiao Zhou, surrendered without a fight. The Shu Han state ceased to exist, and its territories were incorporated into Wei. Many Shu officials and generals were relocated to the Wei capital, Luoyang.
Aftermath:
- Jiang Wei attempted to restore Shu by instigating Zhong Hui’s rebellion (264), but both were killed
- Liu Shan was enfeoffed as Duke of Anle (安樂公) and lived out his days in Luoyang
- Many Shu descendants later served in the Jin dynasty that succeeded Wei
