The Communist Party USA, ideologically committed to foster a socialist revolution in the United States, played a significant role in defending the civil rights of African Americans during its most influential years of the 1930s and 1940s. In that period, the African-American population was still concentrated in the South, where it was largely disenfranchised, excluded from the political system, and oppressed under Jim Crow laws. By 1940, nearly 1.5 million African Americans had migrated out of the South to northern and midwestern cities and become urbanized, but they were often met with discrimination, especially among working-class ethnic whites whom they competed for jobs and housing. The labor struggle continued, and many unions discriminated against black people. Additional migration of another 5 million African Americans out of the South continued during and after World War II, with many going to West Coast cities, where the defense industry had expanded dramatically and offered jobs. History 1919–1928: early years When the Communist Party USA was founded in the United States, it had almost no black members.

Debs, were committed opponents of racial segregation, many in the Socialist Party were often lukewarm on the issue of racism. They considered discrimination against black workers to be an extreme form of capitalist worker exploitation. In addition, the party's allegiance with unions that discriminated against minority workers compromised its willingness to attack racism directly; it did not seek out African-American members, nor did it hold recruitment drives where they lived. Some African Americans disaffected by Socialist attitudes joined the Communist Party; others went to the African Blood Brotherhood (ABB), a socialist group with a large number of Jamaican émigrés in its leadership, whose political philosophy was essentially Marxist in nature. The Communist Party at first repeated the economic position of the Socialist Party. Committed from the outset to bringing about world revolution, the party sympathized with anti-colonial and "national liberation" movements around the globe. Its view of the
