Abd al-Rahman I
Silo (died 783) was the king of Asturias from 774 to 783, succeeding Aurelius. He came to the throne upon his marriage to Adosinda, daughter of Alfonso I ("Alfonso the Catholic"). He moved the capital of the Kingdom of Asturias from Cangas de Onís to Pravia, closer to the center of the kingdom. He was a contemporary of Abd al-Rahman I, Umayyad Emir of Córdoba, and of Charlemagne.
