At the direction of the Soviet Union, the Communist Party USA (CPUSA) and its members were active in the civil rights movement for African Americans. The CPUSA, at the time following Stalin's "theory of nationalism", favored the creation of a separate nation for African Americans to be located in the American Southeast where the greatest proportion of the black population was concentrated. In 1941, after Germany invaded the Soviet Union, Communist International ordered the CPUSA to abandon civil rights work and focus on supporting U.S. entry into World War II.
