'The Negro Question in the U.S.' (1936)
By Sol Auerbach
aka James S. Allen (pseudonym)
http://www.marx2mao.com/Other/NQ36.pdf A pretty thorough and methodical history of blacks in the South from the end of Reconstruction to communist party led unionizing and integration campaigns in the south in the 1930's and concluding with chapters proposing a sovereign predominantly black interracial communist government in the US South and the confiscation of land and property from rich whites and its redistribution to poor blacks and whites.
I think the book is an ideal prelude to Harry Haywood's autobiography 'Black Bolshevik' which describes a predominantly black communist yet interracial militant (as in armed and often willing to take on southern police) sharecropping Union in Alabama in the 1930's which spread to other states and was a significant step towards dismantling the strongholds of American power in the South and which failed not because of racist southerners with guns but because CPUSA chairman Earl Browder forced the abandonment of the program about 1936.
Musician Pete Seeger in an interview mentioned a book entitled 'The Challenge of Interracial Unionism' which is a history of the perseverance of non-conformist interracial mine worker unions in Alabama from the 1870's to the 1920's which indicates to me that Alabama apparently preserved the essence of the antebellum Underground Railroad throughout the Jim Crow era.
Harry Haywood also wrote a classic entitled 'Negro Liberation' in 1948 which argues for a sovereign communist South and which criticizes black conformist groups like the NAACP and the Urban League which in spite of their rhetoric have leaders like the Democrat Party which bows to the immoral white power structure at every critical point and run away from ideas which are deemed too radical and beyond the pale. In other words, they are the black bourgousie conformists - although it's necessary to recognize the white chauvinism is the chief problem.
