St. Louis's father was King Charles II of Naples and Sicily. Charles, then a prince, was imprisoned by the King of Aragon; as a condition of Charles' release in 1288, Louis and two brothers were sent to Barcelona as hostages. There Louis was cheerful and took part in sports with other prisoners. He was also influenced by the Franciscans, and he prayed with them at night. Louis was given his freedom after seven years when a treaty was concluded with King James II of Aragon. It was proposed that Louis marry King James' sister, but he refused both marriage and the crown of Naples. He received a papal dispensation to be ordained a priest and consecrated a bishop at the age of 23. Louis went to Rome in 1296, and five days after being professed among the Franciscans, he was consecrated Bishop of Toulouse. AT Toulouse, Louis was modest, wearing an old Franciscan habit, and his devotion was an inspiration to his flock. Within a few months, however, he asked for permission to resign his office, which he had accepted out of obedience, since he felt that its duties were more than he could handle. He died in 1297, not yet 24 years of age.
