Nikephoros Byzantine Emperor

Nikephoros. Named Caesar in 769. Theophanes records him involved in various plots against Emperors. First in May, 776 against his older half-brother Leo IV the Khazar. He was punished via flogging and exile. Second in September, 780 against his sister-in-law, Regent Empress Irene. He was exiled to a monastery. Third in August, 792 against his nephew Constantine VI. He was blinded and placed in confinement within an imperial residence. Fourth in October, 797, against Irene who had deposed her son. He was exiled to her native Athens. Fifth in 812 against Michael I Rangabe. His new exile place was called Aphousia, somewhere in the Sea of Marmara. He does not seem to resurface.
