Emperor Gaozu of Han; "Gaozu of Han", derived from the ''Records of the Grand Historian'', is the commonly used name, even though he was not accorded the temple name Gaozu ("High Ancestor").}} (2561 June 195 BC), also known by his given name Liu Bang, was the founder and first emperor of the Han dynasty, reigning from 202 to 195 BC. He is considered by traditional Chinese historiography to be one of the greatest emperors in history, credited with establishing the first Pax Sinica, one of China's longest golden ages.

Liu Bang was among the few dynastic founders to have been born into a peasant family. He initially entered the Qin dynasty bureaucracy as a minor law enforcement officer in his home town in Pei County, within the conquered state of Chu. During the political chaos following the death of Qin Shi Huang, who had been the first emperor in Chinese history, Liu renounced his civil service position and became a rebel leader, taking up arms against the Qin. He outmanoeuvred rival rebel leader Xiang Yu to invade the Qin heartland and forced the surrender of the Qin ruler Ziying in 206 BC.

After the fall of the Qin, Xiang Yu, as the de facto chief of the rebels, divided the former Qin empire into the Eighteen Kingdoms, with Liu Bang forced to accept control of the poor and remote region of Bashu (present-day Sichuan, Chongqing, and southern Shaanxi), and assuming the title "King of Han". Within the year, Liu Bang broke out with his army and conquered the Three Qins, which started the Chu–Han Contention, a civil war between various forces seeking to inherit the Qin's former supremacy over China.

In 202 BC, Liu Bang emerged victorious following the Battle of Gaixia, unified most of China under his control, and established the Han dynasty, with himself as the emperor. During his reign, Liu Bang reduced taxes and corvée labour, promoted Confucianism, and suppressed revolts by the lords of non-Liu vassal states, among many other actions. He also initiated the policy of ''heqin'', a system of arranged marriages between nobles, to maintain peace between the Han and the Xiongnu following the Han defeat at the Battle of Baideng in 200 BC. He died in 195 BC and was succeeded by his son Liu Ying. Provided by Wikipedia
