Norse peoples

Norsemen are a group of Germanic people who inhabited Scandinavia and spoke what is now called the Old Norse language between c. 800 AD and c. 1300 AD. The language belongs to the North Germanic branch of the Indo-European languages and is the predecessor of the modern Germanic languages of Scandinavia.

Norseman means "man from the North" and applied primarily to Old Norse-speaking tribes living in southern and central Scandinavia. In history, "Norse" or "Norseman" could be any person from Scandinavia, even though Norway, Denmark and Sweden were different sets of people by the Middle Ages.

The Norse Scandinavians established states and settlements in England, Scotland, Iceland, Wales, the Faroe Islands, Ireland, Russia, Belarus, Greenland, France, Belgium, Ukraine, Estonia, Latvia, Lithuania, Germany, Poland and Canada as well as southern Italy.

The Old Frankish word Nortmann "Northman" was Latinised as Normanni and then entered Old French as Normands, whence the name of the Normans and of Normandy, which was settled by Norsemen in the 10th century.
