The Almanac Singers was an American New York City-based folk music group, active between 1940 and 1943, founded by Millard Lampell, Lee Hays, Pete Seeger, and Woody Guthrie. The group specialized in topical songs, mostly songs advocating an anti-war, anti-racism and pro-union philosophy. They were part of the Popular Front, an alliance of liberals and leftists, including the Communist Party USA (whose slogan, under their leader Earl Browder, was "Communism is twentieth century Americanism"), who had vowed to put aside their differences in order to fight fascism and promote racial and religious inclusiveness and workers' rights. The Almanac Singers felt strongly that songs could help achieve these goals.
Cultural historian Michael Denning writes, "The base of the Popular Front was labor movement, the organization of millions of industrial workers into the new unions of the CIO. For this was the age of the CIO, the years that one historian has called 'the largest sustained surge of worker organization in American history'". "By the early 1940s," he continues, "the CIO was dominated by new unions in the metalworking industries--the United Autoworkers, the United Steel Workers, and the United Electrical Workers--and 'industrial unionism' was not simply a kind of unionism but a kind of social reconstruction". It is in the context of this social movement that the story of the Almanac Singers, which formed in early 1941, ought to be seen.
In late 1940 and early 1941 (before America entered World War II) rearmament was putting an end to a decade of unemployment; and labor was at its most militant. As the CIO fought racial discrimination in hiring, it had to confront deep racial divides in its own membership, particularly in the UAW plants in Detroit where white workers sometimes struck to protest the promotion of black workers to production jobs. It also worked on this issue in shipyards in Alabama, mass transit in Philadelphia, and steel plants in Baltimore.
