Justinian II, sometimes known as Justinian the Apostate, was Roman Emperor from AD 685-695. The eldest son of Constantine IV, he succeeded his father as sole emperor after the latter's death from dysentery. Justinian was overthrown in 695 by a popular uprising. His nose was cut off and he was exiled to Crete, where he conspired with the Bulgars to recover the throne. In 705 he invaded Anatolia at the head of the Bulgar army, but was defeated in battle and executed soon after.
