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.
Names of China
The name "Han" (/; ) derives from the Han dynasty (206 BC–220 AD), who presided over China's first "golden age". The Han dynasty collapsed in 220 and was followed by a long period of disorder, including Three Kingdoms, Sixteen Kingdoms, and Southern and Northern Dynasties periods. During these periods, various non-Chinese ethnic groups invaded from the north and conquered areas of North China, which they held for several centuries. It was during this period that people began to use the term "Han" to refer to the natives of North China, who (unlike the invaders) were the descendants of the subjects of the Han dynasty.
