Fruela II was the king of Asturias from 910 to 924 and king of León from 924 to 925. His father was Alfonso III of Asturias and his mother was Jimena of Pamplona. In 910 Fruela and two of his brothers deposed their father, Alfonso, and divided the kingdom amongst themselves. Fruela, the youngest brother, took the original portion (Asturias); Ordoño took Galicia; and García, the eldest, took León. Although Fruela called himself king of a much-diminished Asturias, evidence suggests that his role was subordinate to the king of León.

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".
