Alfonso I of Asturias


Alfonso I of Asturias, called the Catholic, was the third King of Asturias, reigning from 739 to his death in 757. His reign saw an extension of the Christian domain of Asturias, reconquering Galicia and León.
He succeeded his brother-in-law Favila, and was succeeded by his son, Fruela I. Alfonso's youngest son, Mauregatus, also became king, and his daughter Adosinda was consort to king Silo of Asturias. The dynasty started by Alfonso was known in contemporary Al-Andalus as the Astur-Leonese dynasty.

Biography

As the son of Duke Peter of Cantabria, Alfonso held many lands in that region. He is said to have married Ermesinda, daughter of Pelagius, who founded Asturias after the Battle of Covadonga in which he reversed the Moorish conquest of the region. He succeeded Pelagius' son, his brother-in-law, Favila, on the throne after the latter's premature death.
Whether Pelagius or Favila were ever considered kings in their own lifetime is debatable, but Alfonso certainly was. He began a lifelong war against the Moors. In 740, he conquered Galicia and in 754, León. He went as far as La Rioja. However, the few urban populations of these frontier regions fled to his northern dominions, leaving a depopulated buffer between the Christian and Muslim states.
This created the so-called Desert of the Duero, an empty region between the River Duero and the Asturian Mountains. Alfonso intended it this way; he wished to create an area in which any invading army would find survival difficult. Besides the martial aspects, the demographic and cultural effects of this policy on later Asturian, Spanish and Portuguese history is large. It was over a hundred years before the region was repopulated.
The Arab writers speak of the kings of the northwest of Iberia as the Beni Alfons, and appear to recognize them as a Galician royal stock derived from Alfonso I. Alfonso is credited with establishing the shrine of Our Lady of Covadonga, in commemoration of his father in law's victory at the Battle of Covadonga. He and his queen are interred there. Their epitaph reads:

Family

Alfonso had four children. Three were through his marriage to Ermesinda, and one, Mauregatus, was born to a Muslim slave, Sisalda.
