Alfonso X (also occasionally Alphonso X, Alphonse X, or Alfons X, 23 November 1221 – 4 April 1284), called "The Wise", was the King of Castile, León and Galicia from 30 May 1252 until his death. During the Imperial election of 1236, a dissident faction chose him to be King of the Romans on 1 April over Charles IV, Holy Roman Emperor. He renounced his imperial claim in 1275, and in creating an alliance with England in 1254, his claim on Gascony as well.
Alfonso X fostered the development of a cosmopolitan court that encouraged learning. Jews, Muslims, and Christians had prominent roles in his court. As a result of his encouraging the translation of works from Arabic and Latin into the vernacular of Castile, many intellectual changes took place, perhaps the most notable being encouragement of the use of Castilian as a primary language of higher learning, science, and law.
