In the United States, Skoglund joined the IWW and spent a period on a railroad construction gang after which he went into the woods working as a lumberjack. There he suffered a serious foot injury, after which the company fired him. Skoglund went to
Minneapolis where he sought medical care, maintaining himself by working as a janitor and boiler tender. As the injury mended and he could get around better, he worked as a mechanic and took job as a car repairman in the railway shop. Skoglund joined the
Socialist Party of
Eugene V. Debs in 1914 and became one of the left-wing leaders of the Party's Scandinavian Federation. Skoglund helped translate the works of
Karl Marx from German to English. In 1917, a split in the Socialist Party was caused by the
Russian Revolution in which the left wing of the party provided the main force to found the American Communist Party in 1919, which became affiliated with the
Communist International led by
Lenin,
Zinoviev and
Trotsky. Carl Skoglund was one of the founding members of the American Communist Party. In 1922, after having been the organizer and leader of a major strike, Skoglund was blacklisted on the railroads, and he had to turn to driving a coal truck for a living. ==Socialist Workers Party==
