Andronicus II (Andronicus Palaeologus) , 1258-1332, Byzantine emperor (1282-1328), son and successor of Michael VIII. He devoted himself chiefly to church affairs, renewing the schism by renouncing (1282) the union established at the Second Council of Lyons. He made a treaty with the rising kingdom of Serbia. He also made an unsuccessful alliance with Roger de Flor against the Turks but could not prevent their taking most of Asia Minor. His reign, shared from 1295 to 1320 with his son Michael IX, was cut short by his grandson, who forced him into a monastery and became emperor as Andronicus III.
