According to texts written by Mozarabs in northern Iberia during the ninth century, noble Visigoths, in AD 718 elected a man named Pelagius (681-737) as their leader. Pelagius, a son of Favila, who had been a dignitary at the court of the Visigoth King Egica (687-700), established his headquarters at Cangas de Onís, Asturias and incited an uprising against the Umayyad Muslims.
