John Komnenos

John Komnenos (c. 1015–1067) was a Byzantine general and the younger brother of Emperor Isaac I Komnenos. A doux during Isaac's 1057 revolt, he was rewarded with the post of Domestic of the Schools.

A chronicler wrote that John refused the crown when Isaac abdicated in 1059, though the account has been questioned. He withdrew from public life under Constantine X Doukas and died as a monk in 1067. By his wife Anna Dalassene he was the father of Emperor Alexios I.
