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.
Peng Yue
Peng Yue (died 196 BC), courtesy name Zhong, was a prominent military leader and political figure in the late Qin dynasty and early Western Han dynasty. He was involved in the Chu–Han Contention – a power struggle between the Han dynasty's founder, Liu Bang (Emperor Gao), and his rival, Xiang Yu – as an ally of Liu Bang. In recognition of his contributions, Liu Bang granted Peng Yue the title "King of Liang" (梁王) after the Han dynasty was established.
Peng Yue was a native of Changyi (present-day Jinxiang County, Shandong), and was originally a fisherman. Following the Dazexiang Uprising in 209 BC, Peng Yue was nominated by his fellows to be their leader and he led an uprising against the Qin dynasty. Initially, Peng Yue was reluctant to rebel, but obliged eventually and he arranged for his supporters to meet him the next morning. However, his men did not arrive on time and the last one came at noon. Peng Yue said, "Since everyone has chosen me to be the leader, there must be discipline. As there are too many people who were late today, I cannot possibly punish all of them. The last man to arrive will be executed."
