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.
History of East Asia
In 221 BC, the state of Qin succeeded in conquering the other six states, creating the first imperial dynasty of China for the first time. Following the death of the emperor Qin Shi Huangdi, the Qin dynasty collapsed and control was taken over by the Han dynasty in 206 BC. In 220 AD, the Han empire collapsed into the Three Kingdoms. The series of trade routes known as Silk Road began during the Han dynasty.
