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.

Fan Zeng's prediction came true in 202 BC as Xiang Yu eventually lost to Liu Bang in the power struggle for supremacy over China from 206–202 BC, known as the Chu–Han Contention. Xiang Yu committed suicide after his defeat at the Battle of Gaixia, while Liu Bang established the Han dynasty and became its first emperor.
