Emperor Gaozu of Han
Emperor Gaozu of Han (; 256 BCE – 1 June 195 BCE), born Liu Bang (劉邦), was the founder and first emperor of the Han dynasty, reigning from 202 – 195 BCE. He was one of the few dynasty founders in Chinese history who was born in a peasant family.
Government of the Han dynasty
During the Qin dynasty, the first Qin emperor's legitimacy to rule was ultimately decided by his ability to conquer others. However, by the time of Wang Mang's (r. 9–23 AD) reign, the Mandate of Heaven was considered the only legitimate source of imperial authority. This concept was given greater prominence after the state officially sponsored the worship of Heaven over that of the Five Powers in 31 BC. Moreover, the philosophy of the scholar Dong Zhongshu (179–104 BC), which held that a dynasty's rule on earth was bound to greater cosmological cycles in the universe, was officially sponsored by the Han court from Emperor Wu's (r. 141–87 BC) reign onward. The emperor was expected to behave according to proper ritual, ethics, and morals, lest he incur the wrath of Heaven and bring an end to his reign. He became the highest priest in the land. By performing certain religious rites and rituals, the emperor acted as a sacred link between Heaven and Earth.
