<P> Norse activity in the British Isles occurred during the Early Medieval period when members of the Norse populations of Scandinavia travelled to Britain and Ireland to settle, trade or raid . The Norse peoples who came to the British Isles have been generally referred to as Vikings, but it is a matter of debate if the term Viking represented all Norse settlers or just those who raided . </P> <P> At the start of the Early Medieval period, Norse kingdoms of Scandinavia had developed trade links across southern Europe and the Mediterranean, giving them access to foreign imports such as silver, gold, bronze and spices . These trade links also extended westward into Ireland and the British Isles . </P> <P> In the last decade of the 8th century AD, Norse raiders sacked a series of Christian monasteries located in what is now the United Kingdom, beginning in 793, with a raid on the coastal monastery of Lindisfarne on the east coast of England . The following year they sacked the nearby Monkwearmouth - Jarrow Abbey, and in 795 they attacked again, raiding Iona Abbey on Scotland's west coast . </P> <P> During the Early Medieval period, Ireland and Britain were culturally, linguistically and religiously divided into various peoples . The languages of the Celtic Britons and Gaels were descended from the Celtic languages spoken by those of Iron Age Europe . In Ireland, parts of western Scotland, as well as the Isle of Man, people were speaking an early form of Gaelic known as Old Irish . There may have been another pre-Indo - European language spoken by the Erainn up until the 8th century in what is today Kerry, but this is likely to have been Celtic or some other Indo - European language . In Western Britain, which includes; Cornwall, Cumbria, Wales, and Southwest Scotland, the Celtic Brythonic languages were spoken, with modern descendants such as Welsh and Cornish still being used . In Northern Britain, past the Forth and Clyde rivers which constitutes a large portion of modern - day Scotland, dwelled the Picts who spoke the Pictish language . Due to the scarcity of writing in Pictish, all of which can be found in Ogham, views are conflicted as to whether Pictish was Celtic like the southernly languages, or perhaps even a non-Indo - European language like Basque . However, most inscriptions and place names hint towards the Picts being Celtic in language and culture . Most peoples of Britain and Ireland had already predominantly converted to Christianity from their older, pre-Christian polytheistic religions . In contrast to the rest of the isles though, much of southern Britain was considered to be part of Anglo - Saxon England, where Anglo - Saxon migrants from continental Europe had settled during the 5th century CE, bringing with them their own Germanic language (known as Old English), a polytheistic religion (Anglo - Saxon paganism) and their own distinct cultural practices . By the time of the Viking incursions though, Anglo - Saxon England had too become mostly Christian . </P>
