Alfonso X of Castile

King of Castile and León from 1252 to 1284

Alfonso X (also known as the Wise, Spanish: el Sabio; 23 November 1221 – 4 April 1284) was King of Castile, León and Galicia from 1 June 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.
