The exact circumstances of the succession upon Fruela's death one year later are unclear, but the son of Fruela, Alfonso Fróilaz, became king in at least part of the kingdom when his father passed.

Sancho Ordóñez, Alfonso, and Ramiro, the sons of Ordoño II, claimed to be the rightful heirs and rebelled against their cousin.

With the support of king Jimeno Garcés of Pamplona, they drove Alfonso Fróilaz to the eastern marches of Asturias, and divided the kingdom among themselves with Alfonso Ordóñez receiving the crown of León and his elder brother Sancho being acclaimed king in Galicia.

[1] Alfonso IV resigned the crown to his brother Ramiro in 931 and went into a religious house.

He was defeated, blinded, and sent back to die in the cloister of Sahagún.
