James II, c.1260–1327, king of Aragón and count of Barcelona (1291–1327), king of Sicily (1285–95). He succeeded his father, Peter III, in Sicily and his brother, Alfonso III, in Aragón. James defended Sicily against the claims of Charles II of Naples until 1295, when he relinquished the island in exchange for the title to Sardinia and Corsica. (Sardinia was annexed in 1323–24, but he did not take Corsica.) James later supported Charles against the former's own brother, who had been proclaimed king of Sicily as Frederick II. James was succeeded in Aragón by his son Alfonso IV.
