1911 Encyclopædia Britannica/Alexander II
ALEXANDER II., king of Epirus, succeeded his father Pyrrhus, 272 B.C. He attacked Antigonus Gonatas and conquered the greater part of Macedonia, but was in turn driven out of both Epirus and Macedonia by Demetrius the son of Antigonus. He subsequently recovered his kingdom by the aid of the Acarnalians and Aetolians. He died about 260 (Polybius ii. 45, ix. 34; Plutarch, Pyrrhus, 9; Justin xviii. 1, xxvi. 2, xxviii. 1).
