The Han Dynasty (206 BC-220 CE) was the second imperial dynasty of China, preceded by the Qin Dynasty (221-206 BCE) and succeeded by the Three Kingdoms (220-265 CE). It was founded by the peasant rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han. It was briefly interrupted by the Xin Dynasty (9-23 CE) of the former regent Wang Mang. This interregnum separates the Han into two periods: the Western Han (206 BC-9 CE) and Eastern Han (25-220 CE). Spanning over four centuries, the period of the Han Dynasty is considered a golden age in Chinese history. To this day, China's majority ethnic group refers to itself as the "Han people".
