Dynastic Struggle for the Throne of León (925 CE)

Following the death of King Fruela II in 925 CE, a succession crisis erupts between the sons of Ordoño II and their cousin, Alfonso Fróilaz, son of Fruela.

• Alfonso Fróilaz, already King of Galicia, claims Asturias and León, asserting his right as the direct heir of Fruela II.
• However, Sancho Ordóñez, Alfonso IV, and Ramiro II, the sons of Ordoño II, dispute his claim, rebelling against their cousin and asserting their own rightful succession as the legitimate heirs of their father.

This internal struggle marks a pivotal moment in the political fragmentation of the Kingdom of León, with rival factions vying for control over the Asturian-Leonese throne.

The Ordóñez Brothers Overthrow Alfonso Fróilaz and Divide the Kingdom (925 CE)

With the support of King Jimeno Garcés of Pamplona, the Ordóñez brothers—Sancho Ordóñez, Alfonso IV, and Ramiro II—successfully defeat and depose their cousin Alfonso Fróilaz. They force him to retreat to the eastern marches of Asturias, stripping him of his claim to León and Galicia.

Following their victory, the brothers divide the kingdom among themselves:

• Alfonso Ordóñez is crowned King of León as Alfonso IV...

• Sancho Ordóñez, the eldest, is acclaimed King of Galicia.

This partition of the Asturian-Leonese realm reflects the ongoing dynastic struggles and regional fragmentation that characterize the early medieval kingdoms of northern Iberia.
