Skanke is a Norwegian surname, and a former noble family. Connection with the Isle of Man According to the Skanke Family Association in Norway (Skanke-foreningen i Norge), the family can trace its roots to Jemtland in the 14th century with a high degree of certainty, and with less certainty to the Isle of Man before that. The association's shield depicts a blue-armored leg (or shank), spurred in gold, on a field of white. The family's use of a leg motif in its heraldry has been compared with the Manx triskelion. Manx historian George Vaughan Chichester Young, O.B.E., supposed from that similarity that the family descends from the rulers of Manx (who lost their kingdom as a result of the Treaty of Perth and the 1275 loss of the Battle of Ronaldsway). He wrote in his work A Brief History of the Isle of Man: Skankes opposing each other The Kalmar Union was an unstable creation, often shook by struggles between the pro-Danish and pro-Swedish factions. These conditions would lead the family into battle, with relatives ending up on opposing sides in a war of succession. In 1452, knight Örjan 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. The pro-Danish side, led by the knight Olav Nilsson and his brother and fellow knight, Peder Nilsson, came out on top in this struggle. The two brothers belonged to Norwegian pro-Danish forces which repeatedly defeated the Swedish forces of Charles VIII in the area around Trondheim. After their participation in the fighting the brothers received high ranking positions in the administration of Norway. Olav Nilsson Skanke warred with the Hanseatic League Only a few years after becoming the main royal official in Bergen, Olav lost his position due a conflict
