James II of Aragon

James II the Just (10 April 1267 – 2 November 1327), second son of Peter III and Constance II of Sicily, was crowned King of Sicily in 1286 and in 1291 succeeded his brother Alfonso III as King of Aragon.

By the Treaty of Anagni in 1295 he gave up Sicily to the papacy and restored the Balearics to his uncle James II of Majorca; the Sicilians instead placed his brother Frederick on the island's throne. Pope Boniface VIII also granted him rights to Sardinia and Corsica, and James conquered Sardinia in 1324.
