Jin dynasty

The Jin dynasty or the Jin Empire, officially Jin, sometimes distinguished as the Sima Jin or the Two Jins, was an imperial dynasty in China that existed from 266 to 420 CE. It was founded by Sima Yan, posthumously known as Emperor Wu of Jin, who previously served as the regent of the Cao Wei dynasty.

There are two main divisions in the history of the dynasty. The Western Jin (266–316 CE) was established as the successor to Cao Wei after Emperor Wu usurped the throne from Cao Huan. The capital of the Western Jin was initially in Luoyang, though it later moved to Chang'an (modern Xi'an). In 280 CE, after conquering Eastern Wu, the Western Jin ended the Three Kingdoms period and reunited China proper for the first time since the end of the Han dynasty.
