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
In England, the beginning of the Viking Age is dated to 8 June 793, when Vikings destroyed the abbey on Lindisfarne, a centre of learning on an island off the northeast coast of England in Northumberland. Monks were killed in the abbey, thrown into the sea to drown, or carried away as slaves along with the church treasures, giving rise to the traditional (but unattested) prayer—"A furore Normannorum libera nos, Domine", "Free us from the fury of the Northmen, Lord."
