Vikings in Iberia
Viking 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.
Viking Age
After 842, when the Vikings set up a permanent base at the mouth of the Loire river, they could strike as far as northern Spain. They attacked Cádiz in 844. In some of their raids they were crushed either by Kingdom of Asturias or Emirate armies. These Vikings were Hispanicised in all Christian kingdoms, while they kept their ethnic identity and culture in Al-Andalus.
