五胡十六国時代は何年間続いた？
The Sixteen Kingdoms, less commonly the Sixteen States, was a chaotic period in Chinese history from AD 304 to 439, when the political order of northern China fractured into a series of short-lived sovereign states, most of which were founded by the "Five Barbarians," ethnic minority peoples who had settled in northern China during the preceding centuries and participated in the overthrow of the Western Jin dynasty in the early 4th century. The kingdoms founded by ethnic Xiongnu, Xianbei, Di, Jie, Qiang, as well as Han Chinese and other ethnicities, fought against each other and the Eastern Jin dynasty, which succeeded the Western Jin and ruled southern China. The period ended with the unification of northern China in the early 5th century by the Northern Wei, a dynasty that evolved from a kingdom founded by ethnic Xianbei.
