八王の乱
The War of the Eight Princes, Rebellion of the Eight Kings, or Rebellion of the Eight Princes () was a series of civil wars among kings/princes (Chinese: "wáng" 王) of the Chinese Jin dynasty from 291 to 306 AD. The key point of contention in these conflicts was the regency over the developmentally disabled Emperor Hui of Jin. The name of the conflict is derived from the biographies of the eight princes collected in Chapter 59 of the "Book of Jin" ("Jinshu").
