Norway
From the 8th to the 10th century, the wider Scandinavian region was the source of Vikings. The looting of the monastery at Lindisfarne in Northeast England in 793 by Norse people has long been regarded as the event which marked the beginning of the Viking Age. This age was characterised by expansion and emigration by Viking seafarers. They colonised, raided, and traded in all parts of Europe. Norwegian Viking explorers first discovered Iceland by accident in the 9th century when heading for the Faroe Islands, and eventually came across Vinland, known today as Newfoundland, in Canada. The Vikings from Norway were most active in the northern and western British Isles and eastern North America isles.
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).
