The Jin briefly reunified China after the Three Kingdoms but collapsed under nomadic invasions, with the Eastern Jin surviving as a rump state in the south.
The Jin dynasty fragmented after the War of the Eight Princes and the Uprising of the Five Barbarians; Western Jin fell with the sack of Luoyang in 311 CE and the capture of Chang'an in 316 CE, while Eastern Jin lingered until 420 CE when general Liu Yu deposed the last Jin emperor and founded the Liu Song dynasty.
