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.
Guan Ying
Guan Ying (died 176 BC), posthumously known as Marquis Yi of Yingyin, was a Chinese general and chancellor of the early Han.
Guan Ying was from Suiyang (睢陽; present-day Shangqiu, Henan). He served under Liu Bang (posthumously known as Emperor Gaozu), the founder of the Han dynasty, and joined him in rebelling against the Qin dynasty. He also fought on Liu Bang's side in the Chu–Han Contention and assisted him in overcoming his rival, Xiang Yu. After the establishment of the Han dynasty, he served as the "General of Chariots and Cavalry" (車騎將軍). He assisted Liu Bang in putting down Chen Xi's rebellion, killing Chen's general Hou Chang ( "Hóu Chǎng") near Quni ( "Qūnì"; around west of present-day Baoding, Hebei) in 196.
