Michael III


Michael III, also known as “Michael the Drunkard” by his detractors, was emperor of the Byzantine Empire from 842 to 867 CE. Never quite escaping the shadow of his mother Theodora, who ruled as regent in his name until c. 855 CE, or his uncle Bardas, the gifted chief minister, Michael's reign nevertheless saw significant religious and political changes and a strengthening of the empire, especially in the east. He was murdered and succeeded by the very man he had promoted in court and eventually appointed co-emperor, Basil I.
