With the collapse of Roman control throughout Western Europe in the fifth century AD came an influx of differing peoples to Scotland over the next few centuries with some measure of stabilisation from 1000 onwards. Anglo-Saxons, Dalriadians and Vikings as well as many other groups moved in and settled parts of what is now modern Scotland. The Vikings from Scandinavia though sometimes seen as the ram-raiders of Ninth century were also traders and farmers when it suited them. They also brought new technologies such as in metal working and ship building and stimulated trade especially in the North Sea area which also contributing to the mayhem of this period. These factors lead directly to the development and mixing of different cultures and languages particularly in the interplay between the Scandinavian and Gaelic cultures of the Northern Isles and Western seaboard as is seen in the many words being incorporated from Norwegian/Danish in to Gaelic and English and the many place names still used around Scotland.
