In the first half of the 10th century, an intra-family succession squabble, rebellions and rivalries with competing families, in the face of vigorous monarchs to the north and south, led to the sequential loss of all of their land.

WThe Emirate of Córdoba was a Medieval Islamic kingdom in the Iberian Peninsula. Its founding in the mid eighth century would mark seven hundred years of independent Muslim rule in what is now Spain and Portugal.
WViking activity in the Iberian peninsula seems to have begun around the mid-ninth century as an extension of Viking raids on and establishment of bases in Frankia in the earlier ninth century. While connections between the Norse and Eastern Islamic lands were well-established, particularly involving the Rus' along the Volga and around the Caspian Sea, relations with the Western edge of Islam were more sporadic and haphazard. Although Vikings may have over-wintered in Iberia, no evidence has been found for trading or settlement. Indeed, the Iberian peninsula may not have offered particularly wealthy targets, in the ninth to tenth centuries. Sporadic raiding continued until the end of the Viking Age.
