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.
Han Qixian
The first Jurchen conquest(12 century) ended the Liao dynasty. Han was then relocated to the Bureau of Military Affairs and began to serve the new ruler of Northern China. In 1128, he substituted the recently deceased Liu Zongyan as the director of Bureau of Military Affairs. In 1129, Han was appointed the left deputy director of the Department of State Affairs(尚書左僕射). However, as a native Chinese, he was not able to fully govern as a director due to the aboriginal Jurchen conventions.
