The eight founders of Söderköpings Idrottssällskap had a vision when they founded the club with confectioner Paul Granander on 12 December 1917 to develop sports and obtain a home ground. This primary objective was achieved in spring 1920 when Vikingavallen was opened. On 13 April1936 some enterprising young people met in Centralkafeèt in Söderköping and formed Drothems IK which was later named IK Ramunder. Some 86 years later on 15January 2004 Söderköpings Idrottsklubb was formed following the merger of Söderköpings IS and IK Ramunder. The visions of the original founders lives on with the natural development of a strong Söderköping sports club. Since their foundation Söderköpings IK has participated mainly in the middle divisions of the Swedish football league system. The club currently plays in Division 3 Nordöstra Götaland which is the fifth tier of Swedish football. They play their home matches at the Vikingavallen in Söderköping. Söderköpings IK are affiliated to Östergötlands Fotbollförbund.
