Titular king of Naples, born at Angers, son of Louis II., Duke of Anjou and Count of Provence; on the death of his father-in-law, Duke of Lorraine, he in 1431 claimed the dukedom; was defeated and imprisoned; bought his liberty and the dukedom in 1437, in which year he also made an ineffectual attempt to make good his claim to the throne of Naples and Sicily; settled down in Provence and devoted himself to literature and art and to developing the country (1409-1480).
