The historiographical term "Eighteen Kingdoms" (), also translated as "Eighteen States", refers to the eighteen fengjian states in China created by military leader Xiang Yu in 206 BCE, after the collapse of the Qin dynasty.林达礼，中华五千年大事记， 台南大孚书局, 1982, p. 56 The establishment and abolition of the Eighteen Kingdoms marked the beginning and end of a turbulent interregnum known as the Chu–Han Contention.
The details of the feudal division are as follows:

The Eighteen Kingdoms were short-lived. Almost immediately, Tian Rong, dissatisfied with the fact that he was given no domain, rebelled and seized power in Qi, after which he conquered Jiaodong and Jibei, reuniting the old Qi state. Meanwhile, Xiang Yu had Emperor Yi of Chu and King Han Cheng of Hán killed. Thereafter, Liu Bang of Hàn conquered the lands of the Three Qins, thereby formally starting the Chu–Han Contention. Following many battles and changing alliances, Han defeated Chu and subdued all other kingdoms, where Liu Bang appointed vassal kings while making himself the first Emperor of the Han dynasty in 202 BCE.
