Agder

750 CE – 880 CE (approx.)

Petty kingdom on Norway's southern tip whose king, according to the sagas, fought Harald Fairhair at Hafrsfjord.

Origins

Agder, the southernmost coast of Norway, was a small kingdom in the Viking Age. The sagas link it with the Vestfold dynasty through Queen Åsa, daughter of a king of Agder and mother of Halfdan the Black.

Rule and society

Agder faced the Skagerrak and Denmark and lived by farming, fishing and sea trade. Its rulers are known only from late saga tradition, and the boundaries of the kingdom are uncertain.

Decline and legacy

Heimskringla says that Kjotve the Rich, king of Agder, joined the western coalition defeated by Harald Fairhair at Hafrsfjord, traditionally around 872. Agder then passed into the Kingdom of Norway.

Few sources survive for this state; details are uncertain.
