Bermudo I of Asturias

Bermudo I, called the Deacon (c. 750–797), was King of Asturias from 788 or 789 until 791. A son of Fruela of Cantabria and brother of King Aurelius, he was elected by the palace nobility after Mauregatus died, probably to bar Alfonso II's succession.

In 791 an Arab-Berber army invaded Álava and Galicia and defeated him at the Burbia River. Bermudo then abdicated and Alfonso II took the crown; the Chronicle of Alfonso III attributed his abdication to his status as a deacon. Remembered as merciful and pious, he left a son by an unnamed wife who later reigned as Ramiro I.
