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
The end of the Viking Age is traditionally marked in England by the failed invasion attempted by the Norwegian king Harald III (Haraldr Harðráði), who was defeated by Saxon King Harold Godwinson in 1066 at the Battle of Stamford Bridge; in Ireland, the capture of Dublin by Strongbow and his Hiberno-Norman forces in 1171; and 1263 in Scotland by the defeat of King Hákon Hákonarson at the Battle of Largs by troops loyal to Alexander III. Godwinson was subsequently defeated within a month by another Viking descendant, William, Duke of Normandy. Scotland took its present form when it regained territory from the Norse between the 13th and the 15th centuries; the Western Isles and the Isle of Man remained under Scandinavian authority until 1266. Orkney and Shetland belonged to the king of Norway as late as 1469.
