The Han Dynasty, which appeared after the short Qin Dynasty in China's history, was divided into two historical periods: the Western Han Dynasty (202 BC-9 AD) and the Eastern Han Dynasty (25 AD-220 AD), which later historians also called the Han Dynasty. The Western Han Dynasty was founded by Emperor Gaozu Liu Bang, with Chang 'an as its capital. The Eastern Han Dynasty was founded by Liu Xiu, Emperor Guangwu of Han Dynasty, with Luoyang as its capital. In the meantime, there was a short-lived Wang Mang who represented the self-reliant new dynasty of the Han Dynasty (9- 23 AD). In addition, some scholars also listed Shu Han as a continuation of the Han Dynasty and classified it as a part of the Han Dynasty. They believe that Shu Han continued the local separatist regime of the Han Dynasty, so the Han Dynasty died in 263, but most of them put the Shu Han regime established by Shu Han Emperor Liu Bei into the history of the Three Kingdoms.
