While still captive he was overthrown in a palace coup, and when released he was quickly defeated and detained by members of the Doukas family. In 1072, he was blinded and sent to a monastery, where he died of his wounds.

He was elevated to junior emperor in 1070, although he lost this position when his father was overthrown in 1071. Emperor Alexios I Komnenos, after overthrowing Nikephoros III, made Nikephoros doux of Crete, and made him a general.
