Left Wing Section of the Socialist Party
The Left Wing Section of the Socialist Party was an organized faction within the Socialist Party of America in 1919 which served as the core of the dual communist parties which emerged in the fall of that year—the Communist Party of America and the Communist Labor Party of America.
Ludwig Lore's magazine The Class Struggle, established in 1917, was an early theoretical journal of the organized Left Wing in the Socialist Party.
John Reed and Ben Gitlow's Left Wing magazine Voice of Labor was later made the labor paper of the Communist Labor Party.
