Ferdinand (St.) III of Castile, King of Castile and Leon
Also called SAINT FERDINAND, Spanish SAN FERNANDO, king of Castile from 1217 to 1252 and of Leon from 1230 to 1252 and conqueror of the Muslim cities of Córdoba (1236), Jaén (1246), and Seville (1248). During his campaigns, Murcia submitted to his son Alfonso (later Alfonso X), and the Muslim kingdom of Granada became his vassal.
Ferdinand was the son of Alfonso IX of Leon and Berenguela, daughter of Alfonso VIII of Castile. When born, he was the heir to Leon, but his uncle, Henry I of Castile, died young, and his mother inherited the crown of Castile, which she conferred on him. His father, like many Leonese, opposed the union, and Ferdinand found himself at war with him. By his will Alfonso IX tried to disinherit his son, but the will was set aside, and Castile and Leon were permanently united in 1230.
Ferdinand married Beatrice of Swabia, daughter of the Holy Roman emperor, a title that Ferdinand's son Alfonso X was to claim. His conquest of Lower Andalusia was the result of the disintegration of the Almohad state. The Castilians and other conquerors occupied the cities, driving out the Muslims and taking over vast estates.
Ferdinand's second wife was Joan of Ponthieu, whom he married in 1237; their daughter Eleanor married the future Edward I of England in 1254. Ferdinand settled in Seville, where he is buried.
