War of the Eight Princes
The following is a family tree for the Jin dynasty, which ruled a unified China during the Western Jin Dynasty (265–316 AD). Although greatly weakened by the War of the Eight Princes during the reign of the developmentally disabled Emperor Hui, when members of the clan fought among themselves for imperial control, and forced Eastwards after the conquest of their capital in 316 AD, the dynasty nonetheless continued in the form of the Eastern Jin Dynasty until 420 AD.
