Son of the Byzantine emperor Michael I. Imprisoned for political reasons in a monastery in 813 by Leo the Armenian; there he learned about and entered the religious life, taking the name Ignatius. Monk. Priest. Abbot. Patriach of Constantinople in 842. Fought corruption in civil and religious life, even in the highest offices; refused communion to Bardas Caesar due to his acts of incest. Because of his high standards, Ignatius was exiled from 858 to 867, but eventually returned in triumph.
