TheAsturian orAstur-Leonese dynasty (Spanishdinastía asturiana orastur-leonesa,Asturiandinastía asturllionesa), known inArabic as theBanī Adhfūnsh ("sons of Alfonso"),^[1] was the ruling family of the kingdom ofAsturias andLeón from 739 until 1037. Under their rule, the Astur-Leonese kingdom went from a small mountain enclave to one of the dominant powers inHispania.

The first ruling family of Asturias lasted only two generations:Pelagius (718–737) andFafila (737–739). The latter was succeeded by his brother-in-law,Alfonso I, the son of DukePeter of Cantabria and husband of Fafila's sister,Ermesinda. He founded a dynasty that was to last almost 300 years.^[2]

For the first century, rule alternated between Alfonso's descendants and those of his brother,Fruela of Cantabria. With the death of Alfonso I's grandson,Alfonso II (842), Fruela's descendants took the throne permanently, headed byRamiro I. At the death ofAlfonso III (910), the kingdom was divided between his sons. The 10th century was thus characterized by family infighting, which was only brought to an end by the succession ofBermudo II in 984. During this period, however, the power of the neighbouringKingdom of Pamplona waxed and in 1034 the Pamplonans captured León. The rule of the dynasty was brought to an end three years later whenBermudo III was killed in battle against his brother-in-law,Ferdinand of Castile, of theJiménez dynasty of Pamplona, who thereafter assumed the throne.

The historiography produced by and for the dynasty, such as theChronicle of Alfonso III (late 9th century), made Duke Peter a descendant of theVisigothic kingReccared I and stressed the dynasty's supposed Gothic descent.^[3]
