Andronikos I Komnenos

Andronikos I Komnenos (c. 1118–1185), son of the sebastokrator Isaac Komnenos, long intrigued against his cousin Emperor Manuel I and spent years in exile. After Manuel's death in 1180 he marched on Constantinople as protector of the young Alexios II, seized the capital in 1182, and eliminated the regent Maria of Antioch. In September 1183 he was crowned co-emperor and then had Alexios murdered.

As emperor (1183–1185) his brutal reforms curbed the aristocracy and benefited common citizens, but the Norman sack of Thessaloniki in 1185 provoked the uprising in which he was overthrown and killed, the last Komnenian emperor.
