born 912, Cappadocia
died Dec. 10/11, 969, Constantinople
Byzantine emperor (963969).
A powerful military commander, he fought the Arabs in the east, liberated Crete from its Arab rulers (961), and gained control of the eastern Mediterranean. After the death of Romanus II, Nicephorus cooperated in a plot to seize the throne, accepting the crown (963) and marrying Theophano, the regent of the two legitimate heirs. He continued his exploits against the Arabs but was surrounded by discontent and intrigue at home; he retired to a fortified palace, where he was killed by former friends guided by his wife and his chief lieutenant.
