The petty kingdoms of Norway (BokmÄl: smÄrike) were the entities from which the later Kingdom of Norway was founded. Before the unification of Norway in 872 and during the period of fragmentation after King Harald Fairhair's death, Norway was divided in several small kingdoms. Some could have been as small as a cluster of villages, and others comprised several of today's counties.
By the time of the first historical records of Scandinavia, about the 8th century, a number of small political entities existed in Norway. The exact number is unknown, and would probably also fluctuate with time. It has been estimated that there were 9 petty realms in Western Norway during the early Viking Age. Archaeologist Bergljot Solberg on this basis estimates that there would have been at least 20 in the whole country.
