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 in Estonia
The Viking Age in Estonia was a period in the history of Estonia, part of the Viking Age (793–1066 AD). It was not a unified country at the time, and the area of Ancient Estonia was divided among loosely allied regions. It was preceded by the Bronze and Early Iron Ages in Estonia, during which an agrarian society had developed, the Migration Period (450–550 AD), and Pre-Viking Age (550–800 AD) with the Viking Age itself lasting between 800–1050 AD. It is often considered to be part of the Iron Age period which started around 400 AD and ended around 1200 AD, soon after Estonian Vikings were recorded in the "Eric Chronicles" to have sacked Sigtuna in 1187.
