First Christian Iberian kingdom after the Umayyad conquest; founded by Pelagius after the Battle of Covadonga, origin point of the Reconquista.
Transformed into the Kingdom of León in 924 CE when the three successor kingdoms of Asturias, Galicia, and León were reunified under the Leonese crown; the royal court and title shifted definitively to León, ending Asturias as the realm's name.
Kenneth Baxter Wolf's translated Latin chronicles of Visigothic and early Reconquista Iberia, including the Asturian Chronicle of Alfonso III, cover the era of Asturias and Leon's emergence.
