Manuel's death on 24 September 1180 left his 11-year-old son Alexios II Komnenos on the throne. Alexios was highly incompetent in the office, and with his mother Maria of Antioch's Frankish background, made his regency unpopular. Eventually, Andronikos I Komnenos, a grandson of Alexios I, launched a revolt against his younger relative and managed to overthrow him in a violent "coup d'état". Utilizing his good looks and his immense popularity with the army, he marched on to Constantinople in August 1182 and incited a massacre of the Latins. After eliminating his potential rivals, he had himself crowned as co-emperor in September 1183. He eliminated Alexios II and took his 12-year-old wife Agnes of France for himself.
