Kingdom of Asturias
Umayyad occupation and Asturian revolt
Recent archaeological excavations have found fortifications in Mount Homon and La Carisa (near the Huerna and Pajares valleys) dated between the end of the seventh and beginning of the eighth centuries. The Berber fortifications included watchtowers and moats of almost two meters, in whose construction and defense many hundreds may have participated. That would have required a high degree of organization and firm leadership, probably by Pelayo himself. Therefore, experts consider it probable that the construction of the defensive line was intended to prevent the reentry of Moors into Asturias through the mountain passes of Mesa and Pajares.
Initial expansion
Fruela I, Alfonso I's son, consolidated and expanded his father's domains. He was assassinated by members of the nobility associated with the House of Cantabria.
Recognition and later solidification
Ramiro I began his reign by capturing several other claimants to the throne, blinding them, and then confining them to monasteries. As a warrior he managed to defeat a Viking invasion after the Vikings had landed at Corunna, and also fought several battles against the Moors.
