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.
History of the North Sea
The attack on Lindisfarne in 793 is generally considered the beginning of the Viking Age.
For the next 250 years the Scandinavian raiders of Norway, Sweden, and Denmark dominated the North Sea, raiding monasteries, homes, and towns along the coast and along the rivers that ran inland. According to the "Anglo-Saxon Chronicle" they began to settle in Britain in 851. They continued to settle in the British Isles and the continent until around 1050.
