Donghan

The Han dynasty was an imperial dynasty of China established by Liu Bang, and preceded by the short-lived Qin dynasty (221–206 BC) and interregnum known as the Chu–Han Contention (206–202 BC). It was succeeded by the Three Kingdoms period (220–280 AD) and also briefly interrupted by the Xin dynasty (9–23 AD) established by the usurping regent Wang Mang. It is thus separated into two periods—the Western Han and the Eastern Han (25–220 AD).
