The War of the Eight Princes, Rebellion of the Eight Kings, or Rebellion of the Eight Princes was a series of coups and civil wars among kings/princes of the Chinese Western Jin dynasty from 291 to 306 AD. The period spanned the reign of Emperor Hui of Jin, whose powerful relatives fiercely contended with one another over his regency and succession in light of his developmental disability. The name of the conflict is derived from the biographies of the eight princes collected in Chapter 59 of the Book of Jin.
