Michael III was a Byzantine Emperor who reigned from 842 to 867 AD. He became emperor at a young age after the death of his predecessor, Theophilus. Michael's reign is noted for the restoration of Iconoclasm, a significant religious controversy regarding the use of religious images in the Byzantine Empire. During his rule, Michael III was known for his ambitious and sometimes reckless leadership style. He was heavily influenced by his uncle, Bardas, who played a crucial role in the administration. Michael's reign ended when he was assassinated, leading to the rise of Basil I, who founded the Macedonian dynasty.
