Signature

Alfonso III (c. 848 – 20 December 910), called the Great (Spanish: el Magno), was king of Asturias from 866 until his death. He was the son and successor of Ordoño I. After his death, the Kingdom of Asturias was split between his sons, with García inhereting León, Ordoño inhereting Galicia, and Fruela inhereting Asturias.

In later sources, he is the earliest to be called "Emperor of Spain." He was also titled "Prince of all Galicia" (Princeps totius Galletiae^[1]).
