Alfonso X was the king of Castile, León and Galicia from 30 May 1252 until his death in 1284. During the election of 1257, a dissident faction chose him to be king of Germany on 1 April. He renounced his claim to Germany in 1275, and in creating an alliance with the Kingdom of England in 1254, his claim on the Duchy of Gascony as well.
Alfonso X fostered the development of a cosmopolitan court that encouraged learning. Jews, Muslims, and Christians were encouraged to have prominent roles in his court.
