Fruela I of Asturias

Fruela I (c. 722–768), called the Cruel, was the eldest son of Alfonso I of Asturias and Ermesinda, Pelayo's daughter, and ruled from 757. He suppressed Basque and Galician revolts and defeated a Cordoban army. In 761 the church from which Oviedo grew was founded in his reign.

He murdered his popular brother Vimarano, earning his nickname, and was assassinated at Cangas de Onís in 768. His cousin Aurelius succeeded him, while his son Alfonso later ruled as Alfonso II.
