Justinian II
(Justinian Rhinotmetus), 669711, Byzantine emperor (68595, 70511), son and successor of Constantine IV. He successfully invaded Arab territory but lost the advantage through a truce that ceded much of Asia Minor to the Arabs. His extravagance and despotism and his ministers extortions caused a revolution (695). Justinian had his nose cut off; hence he was given the epithet Rhinotmetus [Gr.,=with the cut-off nose]. He was then exiled. Restored (705) with the help of the Bulgars, he was deposed and beheaded. A series of usurpers occupied the throne from 711. In 717 Leo III established a new dynasty.
