Pelagius was a Visigothic nobleman who founded the Kingdom of Asturias, ruling it from 718 until his death in 737. Through his victory at the Battle of Covadonga, he is credited with beginning the Reconquista, the Christian reconquest of the Iberian peninsula from the Moors. He established an independent Christian state in opposition to Moorish hegemony. The chief sources for Pelagius's life and career are two Latin chronicles written in the late ninth century in the kingdom he founded. The former is the Chronica Albeldensia, written at Albelda towards 881, and the latter is Chronicle of Alfonso III, which was revised in the early century.
