Soviet policy drove thousands of Blacks into the CPUSA.

Evidence

Lenin had compelled the American Communist Party to take the Black American as a critical element in its policy and organization. Stalin, himself a member of a Russian national minority, had been the authority through which the Comintern and the American Communist Party had come to recognize Blacks as an oppressed nation. And for a while the policies directly influenced by these two Bolsheviks had been successful: thousands of Blacks came into the CPUSA during the 1930s in response to the party’s attentions and expressed intentions. — Cedric J.
