Byzantine Empire /
(?-829) Byzantine emperor 820-829.
Michael proved to be an able leader, bringing stability to the empire after decades of unrest and power struggles. He did much to restore the administration of the military. So successful were his efforts, that his descendants ruled for more than 200 years. Still, because of a rebellion by Thomas the Slavonian, the Byzantines suffered a number of hard defeats, in which Crete was conquered by the Abbasids.
But his background represented a problem for his legitimacy as an emperor, coming from a family belonging to a Judeo-Christian sect labelled heretical by the central church.
Although he opposed the veneration of icons, Micheal proved to be mild in his treatment of supporters of Icon worship. Many prisoners of faith were freed, and exiled leaders were invited back to Constantinople, of whom the former Patriarch Nicephorus and Theodore of Stoudios were the foremost (see Christian iconoclasm).
