The Kingdom of Norway as a unified realm dates to the reign of King Harald I Fairhair in the 9th century. His efforts in unifying the petty kingdoms of Norway resulted in the first known Norwegian central government. The country, however, soon fragmented and was collected into one entity in the first half of the 11th century, and Norway has retained a monarchy since that time. Traditionally, it has been viewed as being ruled by the Fairhair dynasty, though modern scholars question whether the eleventh century kings and their successors were truly descendants of Harald.
