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 expansion
Our knowledge of Vikings in Iberia is mainly based on written accounts, many of which are much later than the events they purport to describe, and often also ambiguous about the origins or ethnicity of the raiders they mention. A little possible archaeological evidence has come to light, but research in this area is ongoing. Viking activity in the Iberian peninsula seems to have begun around the mid-ninth century as an extension of their raids on and establishment of bases in Frankia in the earlier ninth century, but although Vikings may have over-wintered there, there is as yet no evidence for trading or settlement.
