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.
Sweden
During the early stages of the Scandinavian Viking Age, Ystad in the Danish province Scania and Paviken on Gotland were flourishing centres of trade, but they were not parts of the early Swedish Kingdom. Remains of what is believed to have been a large market dating from 600 to 700 AD have been found in Ystad. In Paviken, an important centre of trade in the Baltic region during the 9th and 10th century, remains have been found of a large Viking Age harbour with shipbuilding yards and handicraft industries. Between 800 and 1000, trade brought an abundance of silver to Gotland, and according to some scholars, the Gotlanders of this era hoarded more silver than the rest of the population of Scandinavia combined.
