Shu Han's founder,Liu Bei (Emperor Zhaolie), had named his dynasty "Han", as he considered it arump state of the Han dynasty and thus the legitimate successor to the Han throne, while the prefix "Shu" was first used by the rival state ofCao Wei to delegitimize the claims of the Shu Han state to orthodox succession.[4] Later on when writing theRecords of the Three Kingdoms, the historian,Chen Shou, also used the prefix "Shu" to describe Liu Bei's state of Han as a historiographical prefix to differentiate it from the many other states officially named "Han" throughout Chinese history.[5]
From the territories he gained, Liu Bei established a position for himself in China during the final years of the Han dynasty. However, in 219, the alliance between Liu Bei and his ally,Sun Quan, was broken when Sun sent his general,Lü Meng, toinvade Jing Province. Liu Bei lost his territories in Jing Province to Sun Quan.Guan Yu, the general guarding Liu Bei's assets in Jing Province, was captured and subsequently executed by Sun Quan's forces.
Cao Cao died in 220, and was succeeded by his son,Cao Pi, who forced the last Han ruler,Emperor Xian, to abdicate the throne in his favour. Cao Pi then established the state ofCao Wei, and declared himself emperor. Liu Bei contested Cao Pi's claim to the throne, and proclaimed himself "Emperor of Han" in 221. Although Liu Bei is widely seen as the founder of Shu Han, he never claimed to be the founder of a new dynasty; rather, he viewed Shu Han as a continuation of the Han dynasty.
To distinguish the state from other historical Chinese states of the same name, historians have added a relevant character to the state's original name: the state that called itself "Han" (漢) is also known as "Shu Han" (蜀漢) or just "Shu" (蜀).
Liu Bei ruled as emperor for less than three years. In 222, he launched a campaign againstSun Quan to retakeJing Province and avengeGuan Yu, culminating in theBattle of Xiaoting. However, due to grave tactical mistakes, Liu Bei suffered a crushing defeat at the hands of Sun Quan's general,Lu Xun, and lost the bulk of his army. He survived the battle and retreated toBaidicheng, where he died from illness a year later.

Before Liu Bei's death, he appointed thechancellor Zhuge Liang and the generalLi Yan as regents to his son,Liu Shan. The young Liu Shan was only 16 years old, making him the youngest of the rulers of the Three Kingdom states, and Liu Bei expected the two regents to assist Liu Shan in managing state affairs. Zhuge Liang was thede facto head of the Shu government throughout Liu Shan's reign, and was responsible for most of Shu's policies during his regency.
When Liu Shan succeeded his father, Shu was the weakest of the three major powers. Following his father's defeat in 221, the portion of Jing Province previously held by Shu was now firmly under the control of Wu. Shu only included the western lands ofYi Province, while Wei controlled all of the northern lands, and Wu controlled all the lands from the east of Yi Province to the southern and eastern coastlines. Meanwhile, Shu's population was not large enough to stand against the rival state of Wei.[6] This greatly limited Shu in terms of resources and manpower; although the country could efficiently defend itself, Shu could not easily launch successful campaigns. As such, Zhuge Liang parleyed for peace with Wu, and reaffirmed the alliance between Sun Quan and Shu — with the former even recognising Sun Quan's legitimacy when the latter broke with Wei, and declared himself "Emperor of Wu" in 229. In order to strengthen the Shu Han state's authority in the remote southern region ofNanzhong, Zhuge Liang alsolaunched an expeditionary force there in 225 to quell local rebellions, and the growing influence of theNanman (literal: southern barbarians) in the region.
Zhuge Liang advocated an aggressive foreign policy towards Wei, because he strongly believed it was critical to the survival of Shu and its sovereignty. Between the years of 228 and 234, he launched a series offive military campaigns against Wei, with the aim of conqueringChang'an, a strategic city located on the road to the Wei capital,Luoyang. Most of the battles were fought around present-dayGansu andShaanxi provinces. However, aside from gainingJiang Wei as an officer in 228, and the Wudu and Yinping commanderies, Shu failed to achieve any significant victories or lasting gains in the five expeditions. During his final campaign where he fought against the Wei general,Sima Yi, an already taxed and ill Zhuge Liang died under the strain of the long stalemate with the Wei forces at theBattle of Wuzhang Plains.
After Zhuge Liang's death, the Shu government was then headed byJiang Wan,Fei Yi, and others, and Shu temporarily ceased its aggression towards Wei. In 244, the Wei regent,Cao Shuang, launched an invasion of Hanzhong. Despite being outnumbered 2-to-1, the Shu forces defeated the invading combatants at theBattle of Xingshi, with the humiliated Wei forces fleeing. Between 247 and 262, the Shu general,Jiang Wei, resumed Zhuge Liang's legacy by leadinga series of military campaigns against Wei, but also failed to make any significant territorial gains.
In 263, armies led by the Wei generalsDeng Ai andZhong Hui attacked Shu, and conquered its capital,Chengdu, without much struggle — the state having been exhausted by Jiang Wei's ill-fated campaigns. In the same year, Liu Shan surrendered to Deng Ai outside Chengdu, marking the end of Shu. In spite of this, Jiang Wei attempted to incite conflict between Deng Ai and Zhong Hui, in the hope of taking advantage of the situation to revive Shu. Zhong Hui captured Deng Ai, and openly rebelled against the Wei regent,Sima Zhao, but the revolt was suppressed by Wei forces. Jiang Wei, Zhong Hui, and Deng Ai were killed in the struggle.
Liu Shan was brought toLuoyang, where he met with Sima Zhao, and was awarded the title of "Duke of Anle." He lived a comfortable and peaceful life in Luoyang until the end of his days.
Shu was not merely a nation at war. During peacetime, the Shu state began many irrigation and road-building projects designed to improve the economy. Many of these public works still exist and are widely used. For example, theZipingpu Dam is still present nearChengdu,Sichuan. These works helped improve the economy of southwestern China, and can be seen as the beginning of economic activity in Sichuan. It also promoted trade with southern China, which was then ruled by Eastern Wu.[citation needed]
Liu Shan was posthumously granted the title of "Duke Si of Anle" (安樂思公) by theJin dynasty. He was later posthumously honoured as "Emperor Xiaohuai" (孝懷皇帝) byLiu Yuan, the founder of theHan-Zhao state of theSixteen Kingdoms. He is also referred to as the "Later Lord" (後主) in some historical texts.
