Kings of the Han dynasty
The kings from other dynasties (, "yìxìng wáng") were mostly remnants of the rebellion against the Qin dynasty. Following the Dazexiang Uprising, many noblemen rose in rebellion. Heirs, pretenders, and warlords called themselves "kings" and claimed sovereignty as continuations of the six states previously suppressed by Qin. Among these, Chu was the most powerful. However, its rightful ruler Huai II was assassinated on the orders of the warlord Xiang Yu and the 18 Kingdoms Xiang had formed rose in rebellion against him. Liu Bang, king of Han, ultimately defeated Chu and established the new Han dynasty. The kings who had sided with him were then permitted to maintain their titles and lands. A few other kingdoms were also formed by Liu Bang for generals and favorites.
Liu Bei
Liu Bei (; ; 161 – 10 June 223), courtesy name Xuande, was a warlord in the late Eastern Han dynasty who founded the state of Shu Han in the Three Kingdoms period and became its first ruler. Despite early failings compared to his rivals and lacking both the material resources and social status they commanded, he gathered support among disheartened Han loyalists who opposed Cao Cao, the warlord who controlled the Han central government and the figurehead Emperor Xian, and led a popular movement to restore the Han dynasty through this support. Liu Bei overcame his many defeats to carve out his own realm, which at its peak spanned present-day Sichuan, Chongqing, Guizhou, Hunan, and parts of Hubei and Gansu.
