Emperor Gaozu (256 or 247 – 1 June 195 BC), commonly known by his temple name Gaozu, personal name Liu Bang, courtesy name Ji, was the founder and first emperor of the Han dynasty. He ruled China from 202–195 BC. Gaozu was one of the few dynasty founders in Chinese history originating from the peasant class. During his reign, Liu Bang reduced taxes and corvée, promoted Confucianism, and suppressed revolts by the rulers of some vassal states, among other things. He also initiated the policy of heqin to maintain peace between the Han Empire and the Xiongnu after he lost to the Xiongnu at the Battle of Baideng in 200 BC. Liu Bang died in 195 BC and was succeeded by his son, Liu Ying (Emperor Hui).
