Mauregatus of Asturias

Mauregatus the Usurper was the king of Asturias from 783 to 788 or 789. He was an illegitimate son of Alfonso I, supposedly by a Moorish serf. He usurped the throne on the death of Silo, the husband of his half sister Adosinda, earning himself the nickname of the Usurper. The nobility had elected Alfonso II at Adosinda's insistence, but Mauregatus assembled a large army of supporters and forced Alfonso into exile in Álava.
