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.
Emperor Jing of Han
Emperor Jing of Han (188 BC – 9 March 141 BC), personal name Liu Qi (), was the sixth emperor of the Chinese Han dynasty from 157 to 141 BC. His reign saw the limiting of the power of the feudal kings/princes which resulted in the Rebellion of the Seven States in 154 BC. Emperor Jing managed to crush the revolt and princes were thereafter denied rights to appoint ministers for their fiefs. This move helped to consolidate central power which paved the way for the long reign of his son Emperor Wu of Han.
