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 term Varangian remained in usage in the Byzantine Empire until the 13th century, largely disconnected from its Scandinavian roots by then.
Having settled Aldeigja (Ladoga) in the 750s, Scandinavian colonists were probably an element in the early ethnogenesis of the Rus' people, and likely played a role in the formation of the Rus' Khaganate. The Varangians (Varyags, in Old East Slavic) are first mentioned by the Primary Chronicle as having exacted tribute from the Slavic and Finnic tribes in 859. It was the time of rapid expansion of the Vikings in Northern Europe; England began to pay Danegeld in 859, and the Curonians of Grobin faced an invasion by the Swedes at about the same date.
In 862, the Finnic and Slavic tribes rebelled against the Varangian Rus, driving them overseas back to Scandinavia, but soon started to conflict with each other. The disorder prompted the tribes to invite back the Varangian Rus "to come and rule them" and bring peace to the region. This was a somewhat bilateral relation with the Varagians defending the cities that they ruled. Led by Rurik and his brothers Truvor and Sineus, the invited Varangians (called Rus') settled around the town of Novgorod (Holmgard).
