Overview
Alexander (, Alexandros, 23 November 8706 June 913) was briefly Roman emperor from 912 to 913, and the third emperor of the Macedonian dynasty.
Life
Born in the purple, Alexander was the third son of Emperor Basil I and Eudokia Ingerina. Unlike his older brother Leo VI the Wise, his paternity was not disputed between Basil I and Michael III because he was born years after the death of Michael. As a child, Alexander was crowned as co-emperor by his father in early 879, following the death of Basil's son Constantine.
Upon the death of his brother Leo on 11 May 912, Alexander succeeded as senior emperor alongside Leo's young son Constantine VII. He was the first Byzantine emperor to use the term "autocrator" on coinage to celebrate the ending of his thirty-three years as co-emperor. Alexander promptly dismissed most of Leo's advisers and appointees, including the admiral Himerios, the patriarch Euthymios, and the Empress Zoe Karbonopsina, the mother of Constantine VII whom he locked up in a nunnery. The patriarchate was again conferred on Nicholas Mystikos, who had been removed from this position because he had opposed Leo's fourth marriage.
During his short reign, Alexander found himself attacked by the forces of Al-Muqtadir of the Abbasid Caliphate in the East, and provoked a war with Simeon I of Bulgaria by refusing to send the traditional tribute on his accession. Alexander died soon after, allegedly because of a stomach disease caused by excessive eating and alcohol.
