The Jin Dynasty was a dynasty in Chinese history, lasting between the years 265 and 420 CE. There are two main divisions in the history of the Dynasty, the first being Western Jin and the second Eastern Jin (317–420). Western Jin was founded by Sima Yan, with its capital at Luoyang, while Eastern Jin was begun by Sima Rui, with its capital at Jiankang. The two periods are also known as Liang Jin and Sima Jin by scholars, to distinguish this dynasty from other dynasties that use the same Chinese character, such as the Later Jin Dynasty.
