James of Aragon (29 September 1296 – July 1334) was the eldest child of King James II. His mother was Blanche of Naples, the second of his father's four wives. As the king's eldest son, James was not only an infante but also heir apparent to the Crown of Aragon, a realm stretching from north-eastern Spain to Sardinia and Corsica. He is best known for his unexpected decision to renounce his marriage and right to the throne and become a monk.[1]
