The first of the two periods, the Western Jin Dynasty (ch. 西晉, 265-316), was founded by Emperor Wu. Although providing a brief period of unity after conquering the Kingdom of Wu in AD 280, the Jin could not contain the invasion and uprising of nomadic peoples after the devastating War of the Eight Princes. The capital was Luoyang until 311 when Emperor Huai was captured by the forces of Han Zhao. Successive reign of Emperor Min lasted four years in Chang'an until its conquest by Former Zhao in 316.
Meanwhile remnants of the Jin court fled from the north to the south and reestablished the Jin court at Jiankang, which was located south-eastward of Luoyang and Chang'an and near modern-day Nanjing, under Prince of Longya. Prominent local families of Zhu, Gan, Lu, Gu and Zhou supported the proclamation of Prince of Longya as Emperor Yuan of the Eastern Jin Dynasty (ch. 東晉 317-420) when the news of the fall of Chang'an reached the south.
Militaristic authorities and crises plagued the Eastern Jin court throughout its 104 years of existence. It survived the rebellions of Wang Dun and Su Jun. Huan Wen died in 373 before proclaiming himself emperor. Battle of Fei turned out to be a victory of Jin under a short-lived cooperation of Huan Chong, brother of Huan Wen and the Prime Minister (or Imperial Secretariat) Xie An. Huan Xuan, son of Huan Wen, usurped and changed the name of the dynasty to Chu. He was toppled by Liu Yu, who ordered the hanging of the reinstated but retardedEmperor An. The last emperor and brother of Emperor An, Emperor Gong, was installed in 419. Abdication of Emperor Gong in 420 in favor of Liu Yu, then Emperor Wu, ushered in the Song Dynasty and the Southern Dynasties.
In a strict academic sense it refers to the period between the foundation of the Wei in 220 and the conquest of the Wu by the JinDynasty in 280.
The later part of this period was marked by the destruction of Shu by Wei (263), the overthrow of Wei by the JinDynasty (265), and the destruction of Wu by Jin (280).
This was similar to the deposal of Emperor Xian of the Han Dynasty by Cao Pi, the founder of the Wei Dynasty.
