History of The Socialist Movement in The United States - 1919-1945

1919-1945

In 1919, John Reed, Benjamin Gitlow and other Socialists formed the Communist Labor Party, while Socialist foreign sections led by Charles Ruthenberg formed the Communist Party. These two groups would be combined as the Communist Party of the United States of America (CPUSA). The Communists organized the Trade Union Unity League to compete with the AFL and claimed to represent 50,000 workers.

In 1928, following divisions inside the Soviet Union, Jay Lovestone, who had replaced Ruthenberg as general secretary of the CPUSA following his death, joined with William Z. Foster to expel Foster's former allies, James P. Cannon and Max Shachtman, who were followers of Leon Trotsky. Following another Soviet factional dispute, Lovestone and Gitlow were expelled, and Earl Browder became party leader.

Cannon, Shachtman, and Martin Abern then set up the Trotskyist Communist League of America, and recruited members from the CPUSA. The League then merged with A. J. Muste's American Workers Party in 1934, forming the Workers Party. New members included James Burnham and Sidney Hook.

By the 1930s the Socialist Party was deeply divided between an Old Guard, led by Hillquit and younger Militants, who were more sympathetic to the Soviet Union, led by Norman Thomas. The Old Guard left the party to form the Social Democratic Federation. Following talks between the Workers Party and the Socialists, members of the Workers Party joined the Socialists in 1936. Once inside they operated as a separate faction. The Trotskyists were expelled from the Socialist Party the following year, and set up the Socialist Workers Party (SWP) and the youth wing of the Socialists, the Young People's Socialist League (YPSL) joined them. Shachtman and others were expelled from the SWP in 1940 over their position on the Soviet Union and set up the Workers Party. Within months many members of the new party, including Burnham, had left. The Workers Party was renamed the Independent Socialist League (ISL) in 1949 and ceased being a political party.

Some members of the Old Guard formed the American Labor Party (ALP) in New York State, with support from the Congress of Industrial Organizations (CIO). The right wing of this party broke away in 1944 to form the Liberal Party of New York. In the 1936, 1940 and 1944 elections the ALP received 274,000, 417,000, and 496,000 votes in New York State, while the Liberals received 329,000 votes in 1944.
