Jin dynasty (265–420)
The Jin dynasty (Chinese: 晉朝; pinyin: Jìn cháo, IPA: [tɕîn tʂʰɑ̌ʊ]) was a Chinese dynasty lasting between the years AD 265 to 420. There are two main divisions in the history of the dynasty, the first being Western Jin (西晉, 265–316) and the second Eastern Jin (東晉, 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 (兩晉; literally: two Jin) and Sima Jin (司馬晉) by scholars, to distinguish this dynasty from other dynasties that use the same Chinese character, such as the Later Jin dynasty (後晉).
Foundation
The Sima clan was initially subordinate to the Wei dynasty, but the clan's influence and power grew greatly after the coup d'état in 249 known as the incident at Gaoping Tombs. In 263, Sima Zhao unified the lands of Shu and captured Liu Shan, which was followed a year later by Zhong Hui's Rebellion.
In 265, Sima Yan forced Emperor Cao Huan of Wei to abdicate the throne to him, ending Wei and founding the Jin. Sima Yan was enthroned as Emperor Wu of Jin. He named his dynasty after the state of Jin of the Spring and Autumn period that once ruled the Sima clan's home county of Wen in Henei (modern Wen County, Henan). In 280, the Jin conquered Eastern Wu and unified China, but internal conflicts, corruption and political turmoil quickly weakened the dynasty, and the unification lasted only ten years. Upon the advent of the second Jin emperor, Emperor Hui, various imperial princes tried to grab power in the devastating War of the Eight Princes. The Uprising of the Five Barbarians followed, during which large numbers of refugees fled south while the north was occupied by various nomadic groups. This marked the end of the Western Jin dynasty in 316 when the Jin court evacuated to the region south of the Huai River, and the beginning of the Eastern Jin and the Sixteen Kingdoms period.
