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 Finland
Contact between Sweden and what is now Finland was considerable even during pre-Christian times; the Vikings were known to the Finns due to their participation in both commerce and plundering. There is possible evidence of Viking settlement in the Finnish mainland. The Åland Islands probably had Swedish settlement during the Viking Period. However, some scholars claim that the archipelago was deserted during the 11th century.
According to the archaeological finds, Christianity gained a foothold in Finland during the 11th century. According to the very few written documents that have survived, the church in Finland was still in its early development in the 12th century. Later medieval legends from late 13th century describe Swedish attempts to conquer and Christianize Finland sometime in the mid-1150s.
