 In the summer of 1919 the Socialist Party of America (SPA), amidst much acrimony, split into three parts, with the Regular faction controlling the National Executive Committee and the National Office suspending six large language federations for their endorsement of the Left Wing Manifesto around with the Left Wing Section was organizing its forces.While the Finnish Socialist Federation was not one of those endorsing the Left Wing Manifesto, and thus not the subject of sanctions, many in the organization were sympathetic to the revolutionary socialist pronouncements of the Manifesto and disgusted by the actions of the NEC.At its national convention held in Waukegan, Illinois from December 25, 1920, to January 2, 1921, the Finnish Socialist Federation decided to withdraw from the SPA and to instead continue as an independent organization.
