Mauregatus of Asturias Mauregatus the Usurper (Spanish: "Mauregato" ) 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, his brother-in-law (the husband of his half sister Adosinda). The nobility had elected Alfonso II at Adosinda's insistence, but Mauregatus assembled a large army of supporters and forced Alfonso into Álava.
