Alexios Komnenos

Alexios Komnenos was a Byzantine aristocrat and courtier. A son of Andronikos Komnenos and nephew of Emperor Manuel I Komnenos, he rose to the high rank of prōtostratōr in 1167. In 1176 he participated in the Myriokephalon campaign where, following the death of his older brother John, he was raised to the titles of prōtosebastos and prōtovestiarios. Following Manuel's death in 1180, he won the favour, and reportedly became the lover, of Empress-dowager Maria of Antioch. Through her he ruled the Byzantine Empire for two years as de facto regent of the underage emperor Alexios II Komnenos. The aristocracy challenged his dominance, led by the princess Maria Komnene, who plotted to assassinate the prōtosebastos. The plot was discovered and most conspirators arrested, but Maria and her husband fled to the Hagia Sophia, protected by Patriarch Theodosios Borradiotes and the common people of Constantinople.
