The SFKO was founded by Konrad Hallgren (who had served as volunteer in the German forces during the First World War), Sven Hedengren (an officer in the Swedish Army) and Sven Olov Lindholm (a NCO in the Swedish Army). Lindholm and one of the other leading members, Per Engdahl, would both become leading figures in the Swedish far-right.
The SFKO founded in 1926 a militia of sorts, the Stormgruppen Wasa, an organisation similar to the German SA. Sigvard Algot Holmberg a member of the SFKO attacked Per-Albin Hansson of the Swedish Social Democratic Party, who later would serve as premier minister in the Swedish government 1936-1946, in 1928
The SFKO was heavily influenced by Italian fascism and many of the articles in Spöknippet were translations of articles from various Italian magazines. However after a few years it began moving towards the German Nazism instead and Hallgren visited the NSDAP in 1928. And after Hallgren and Lindholm visited the partydays in Nuremberg 1929 the name of the party was changed to Sveriges Nationalsocialistiska Folkparti (SNFP) and became a naziparty.
