A boy becomes sole emperor in Constantinople
When the Byzantine emperor Alexander died on 6 June 913 after barely a year on the throne, his nephew Constantine VII, a boy of seven, became sole emperor. Real power passed to a regency council led by the Patriarch Nicholas Mystikos, and later to Constantine’s mother Zoe and the admiral Romanos Lekapenos. Constantine only ruled in his own right from 945, and became famous as a scholar who wrote handbooks on government and court ceremony.
