These marauders, or pirates, came from Scandinavia--what is now Denmark, Norway, and Sweden. The people who lived there were Norsemen, or Northmen. Those Norsemen who took part in these swift, cruel raids along the coast were called Vikings.

Just as Christian Europe had settled down after the barbarian invasions, followed by the onslaught of Islamic armies, a new wave of barbarian invaders came from the north in the form of the Vikings. These raiders came from the countries we now call Sweden, Denmark, and Norway. The Norsemen (North Men) were skilled craftsmen, navigators and sailors. Viking longships were capable of sailing seas and oceans, as well as maneuvering in very shallow rivers and streams.
