The Norsemen (or Northmen) were a North Germanic linguistic group of the Early Middle Ages, during which they spoke the Old Norse language.
[4] During the late eighth century, Scandinavians embarked on a large-scale expansion in all directions, giving rise to the Viking Age.
[11] The Anglo-Saxon Chronicle, written in Old English, distinguishes between the pagan Norwegian Norsemen (Norðmenn) of Dublin and the Christian Danes (Dene) of the Danelaw.
[citation needed] The Slavs, the Arabs and the Byzantines knew them as the Rus' or Rhōs (Ῥῶς), probably derived from various uses of rōþs-, i.e. "related to rowing", or from the area of Roslagen in east-central Sweden, where most of the Northmen who visited the Eastern Slavic lands originated.
[20] Archaeologists and historians of today believe that these Scandinavian settlements in the East Slavic lands formed the names of the countries of Russia and Belarus.
[citation needed] The Norse Scandinavians established polities and settlements in what are now Great Britain (England, Scotland, Wales), Ireland, Iceland, Russia, Belarus, France, Sicily, Belgium, Ukraine, Estonia, Latvia, Lithuania, Germany, Poland, Greenland, Canada,[24] and the Faroe Islands.
