Louis of Toulouse was a 13th-century Neapolitan prince of the House of Anjou who became a Franciscan bishop. Born in 1274, he spent part of his youth in Catalonia as a hostage, where he studied theology under Franciscan friars. Although he was the heir to the throne of Naples, he renounced his royal claims to embrace a life of poverty and obedience. Consecrated as the Bishop of Toulouse in 1297, he was known for his dedication to the poor before dying at the age of 23.
