The Han dynasty (汉朝) was an imperial dynasty of China, established by Liu Bang and ruled by the House of Liu.
The dynasty was preceded by the short-lived Qin dynasty and a warring interregnum known as the Chu–Han contention, and it was succeeded by the Three Kingdoms period. The dynasty was briefly interrupted by the Xin dynasty established by usurping regent Wang Mang, and is thus separated into two periods—the Western Han and the Eastern Han. Spanning over four centuries, the Han dynasty is considered a golden age in Chinese history, and it has influenced the identity of the Chinese civilization ever since. Modern China's majority ethnic group refer to themselves as the "Han people" or "Han Chinese". The spoken Sinitic language and written Chinese are referred to respectively as the "Han language" (汉语) and "Han characters" (汉字).
