c. 13th century–1290
Alv Erlingsson was a Norwegian nobleman and privateer active in the late thirteenth century. After conflict with the Norwegian crown and regional rivals, he operated in the North Sea and was eventually captured and executed in Denmark.
Alv Erlingsson was born in Ringerike. After inheriting Sarpsborg in 1283 he served as governor of Borgarsyssel, but conflict with Danish interests and the Norwegian crown pushed him into raiding and outlawry; he was captured and executed in Denmark in 1290.
