Battle of Hafrsfjord

The Battle of Hafrsfjord was a great naval battle fought in Hafrsfjord sometime between 872 and 900 that resulted in the unification of Norway, later known as the Kingdom of Norway. After the battle, the victorious Viking chief Harald Fairhair proclaimed himself the first king of the Norwegians, merging several petty kingdoms under a single monarch for the first time.
Although most scholars currently tend to regard the unification as a process lasting centuries, rather than being the result of a single battle, the Battle of Hafrsfjord ranks high in the popular imagination of Norway. It was the conclusion of King Harald I of Norway's declaration to become the sole ruler of Norway. This battle may well have been the largest in Norway up to that time and for a substantial time afterward.
