In 1452, knight Ørjan Karlson Skanke from Jemtland is mentioned as agent of Charles VIII of Sweden. Ørjan was sent to conquer Trondheim, the ancient centre of Norway's kings. Control of this vital city would have greatly strengthened Charles' claim to the throne. The answer from the Danish side came with knight Ørjan's own distant relatives. Olav Nilsson (ca. 1400–1455) was commander of Bergenhus Fortress in Bergen. Olav Nilsson and his brother Peder, marching up from the south and pushing Ørjan out of Trondheim. The same thing happened all over again in 1453 with Ørjan seizing Trondheim and Olav and Peder driving him out once more. This second battle finally concluded the conflict over succession and ended the battles between knights of the Skanke family.
