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.
Government of the Han dynasty
The Han dynasty (202 BC – 220 AD) of ancient China was the second imperial dynasty of China, following the Qin dynasty (221–206 BC). It was divided into the periods of Former Han (202 BC – 9 AD) and Later Han (25–220 AD), briefly interrupted by the Xin dynasty (9–23 AD) of Wang Mang. The capital of Western Han was Chang'an, and the capital of Eastern Han was Luoyang. The emperor headed the government, promulgating all written laws, serving as commander-in-chief of the armed forces, and presiding as the chief executive official. He appointed all government officials who earned a salary of 600 bushels of grain or more (though these salaries were largely paid in coin cash) with the help of advisors who reviewed each nominee. The empress dowager could either be the emperor's actual or symbolic mother, and was in practice more powerful than the emperor, as she could override his decisions. The emperor's executive powers could also be practiced by any official upon whom he bestowed the Staff of Authority. These powers included the right to execute criminals without the imperial court's permission.
