In the eleventh century the northern and central parts of the Scandinavian peninsula were occupied by a people who are often called Lapps but who called themselves Saami. Contemporaries distinguished four main groups of Scandinavians: Danes, Götar, Svear and Norwegians or Northmen. By the year 1200 most of the territory occupied by these Scandinavians had been incorporated in the three medieval kingdoms: Norwegian kingdom, Danish kingdom, and Swedish kingdom. The Danish kingdom was the first to be firmly established. The Swedish kingdom was formed by the unification of the Götar and the Svear. The earliest Scandinavian historians, writing in the twelfth and thirteenth centuries, believed that the Danish kingdom had existed since time immemorial and that the kingdoms of Norway and Sweden were relatively recent creations formed by the unification of many small kingdoms. The founder of the medieval Norwegian dynasty was Harald Hardrada. The earliest of the provincial laws, for the west Norwegian province, survives in a twelfth-century version.
