or ALE'XIUS II. COMNE'NUS (Ἄλεξις or Ἀλέξιος Κομνηνός), emperor of Constantinople, the son of the emperor Manuel Comnenus, was born in 1167, according to Nicetas. In 1179, he married Agnes or Anna, the daughter of king Louis VII. of France, and succeeded his father in 1180, under the guardianship of his mother Maria, the daughter of Raymond, prince of Antioch. They both became victims of the ambition of Andronicus Comnenus, who first compelled the young emperor to sign the death of his mother, and then put Alexis to death in 1183; whereupon he succeeded him on the throne.
