Konstantinos VI (771–798)
Born 771 CE, died 798 CE.
Constantine VI (Greek: Κωνσταντῖνος, romanized: Kōnstantīnos, 14 January 771 – before 805), sometimes called the Blind, was Byzantine emperor from 780 to 797. The only child of Emperor Leo IV, Constantine was named co-emperor with him at the age of five in 776 and succeeded him as sole Emperor in 780, aged nine. His mother Irene exercised control over him as regent until 790, assisted by her chief minister Staurakios. The regency ended when Constantine reached maturity, but Irene sought to remain an active participant in the government. After a brief interval of sole rule Constantine named his mother empress in 792, making her his official colleague. Constantine suffered military defeats and made controversial decisions, such as blinding his loyal general Alexios Mosele and illicitly marrying his mistress, Theodote. Taking advantage of her son's unpopularity, Irene had Constantine deposed, blinded and imprisoned in 797 and seized power for herself alone, becoming the first Empress regnant of the Empire.
