Michael I, Emperor
MICHAEL I, EMPEROR RHANGABES (d. 845), an obscure nobleman who had married Procopia, the daughter of Nicephorus I., and been made master of the palace. He was made emperor in a revolution against his brother-in-law, Stauracius (811).
Elected as the tool of the bigoted orthodox party in the Church, Michael diligently persecuted the iconoclasts on the northern and eastern frontiers of the empire, but meanwhile allowed the Bulgarians to ravage a great part of Macedonia and Thrace; having at last taken the field in the spring of 813, he was defeated near Bersinikia, and Leo the Armenian was saluted emperor in his stead in the following summer. Michael was relegated as a monk to the island of Prote, where he lived unmolested till his death in 845.
