He was the second son of James II and Blanche of Anjou. His reign saw the incorporation of the County of Urgell, Duchy of Athens, and Duchy of Neopatria into the Crown of Aragon.
During the reign of his father, he was the procurator general of the Crown. He married Teresa d'Entença, heiress of Urgell, in 1314. In 1323–1324, he undertook the conquest of Sardinia. He became heir after his older brother James renounced his rights to become a monk. In 1329, he began a long war with the Republic of Genoa. The city of Sassari surrenderd in 1323, but rebelled three more times and was contested by Genoa.
After widowing, Alfonso married Eleanor of Castile, who was betrothed to his brother James, who had refused to consummate the marriage. She was the sister of Alfonso XI of Castile.
