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 the Han dynasty
During the "Rule of Wen and Jing" (the era named after Emperor Wen and his successor Emperor Jing (r. 157–141 BCE)), the Han Empire witnessed greater economic and dynastic stability, while the central government assumed more power over the realm. In an attempt to distance itself from the harsh rule of Qin, the court under these rulers abolished legal punishments involving mutilation in 167 BCE, declared eight widespread amnesties between 180–141 BCE, and reduced the tax rate on households' agricultural produce from one-fifteenth to one-thirtieth in 168 BCE. It was abolished altogether the following year, but reinstated at the rate of one-thirtieth in 156 BCE.
