The United States underwent an increase in labor militancy during the post-war period . 1919 saw a general strike in Seattle , large miners ' strikes , a police strike in Boston , and a nationwide steel strike . The IWW , however , had been nearly destroyed in the previous two years by local criminal syndicalism laws , the federal government , and vigilante violence . It attempted to take credit for some of the strikes , but in reality was too weak to play a significant role . The post-war Red Scare intensified the attacks on the IWW and by the end of 1919 the IWW was practically powerless . In 1919 Canada was hit by a labor revolt , leading to the formation of One Big Union , which was only partly industrial unionist . <!-- To-do: German Revolution: Bock Italian Biennio Rosso: ...

In March 1919 , the Comintern or Third International was founded at a conference in Moscow . The Bolsheviks acknowledged syndicalism 's opposition to socialist reformism and saw them as part of the revolutionary wing of the labor movement . No syndicalists attended the founding convention , mainly because the blockade of Russia by the Allies powers made travel to Moscow near impossible . After long discussions , the CNT opted to join the Comintern , though it classified its adherence as provisional as a concession to detractors of Bolshevism . USI also decided to join , though some like Borghi had reservations about the course of events in Russia . In France , the CGT 's radical minority that had opposed the war enthusiastically supported Bolshevism . They formed the Revolutionary Syndicalist Committees and attempted to push the CGT as a whole to support the Comintern . The General Executive Board of the IWW decided join the Comintern , but this decision was never confirmed by a convention . German and Swedish syndicalists were more critical of Bolshevism from the start . Rocker declared already in August 1918 that the Bolshevik regime was " but a new system of tyranny "
