Alfonso III of Asturias

Who was Alfonso III of Asturias?

Alfonso III, called the Great, was the king of León, Galicia and Asturias from 866 until his death. He was the son and successor of Ordoño I. In later sources he is the earliest to be called "Emperor of Spain." He was also titled "Prince of all Galicia".

Little is known about Alfonso except the bare facts of his reign and of his comparative success in consolidating the kingdom during the weakness of the Umayyad princes of Córdoba. He fought against and gained numerous victories over the Muslims of al-Andalus, nonetheless his kingdom was always inferior to that of the Cordobans, and he was thus forced to pay them tribute.

He defeated a Basque rebellion in 867 and, much later, a Galician one as well. He conquered Oporto and Coimbra in 868 and 878 respectively. In about 869, he formed an alliance with the Kingdom of Pamplona, and solidified this link by marrying Jimena, who is thought to have been daughter of king García Íñiguez, or less likely, a member of the Jiménez dynasty, and also married his sister Leodegundia to a prince of Pamplona.
