Alfonso II, 1152–96, king of Aragón (1162–96) and, as Raymond Berengar V, count of Barcelona (1162–96); son and successor of Raymond Berengar IV of Barcelona and Petronilla of Aragón. He inherited Provence (1166), which he successfully defended against the counts of Toulouse, and Roussillon (1172). He conquered (1171) Teruel from the Moors and, after releasing himself from homage to Alfonso VIII of Castile, concluded with him the Treaty of Cazorla (1179), which reserved the reconquest of Valencia for Aragón. He was succeeded in Aragón by his eldest son, Peter II, and in Provence by a younger son.
