The Union of South Africa and the Soviet Union captures the Communist Party’s history up to 1961, and focuses on its alliance and strategic relationship with the trade union movement, the African National Congress and the Moscow-based Third Communist International. Prof Ndlovu shares more about his book. From its inception in 1921, the Communist Party of South Africa (CPSA) grappled constantly and seriously with the problem of understanding the South African revolution and how to work in solidarity with the African nationalist movement and the African trade union movement. This was done to support a national revolution for the total abolition of the colonial-style exploitation of the African majority. There was no "religious" revelation in which the truth emerged as pure and complete in a single flash. Truth was relative and had to be searched for painfully and slowly, delivering partial answers. Insights needed testing in practical revolutionary work; everything had to be sharpened, refined and brought closer to perfection, as the inspirational revolutionary work and commitment of Johannes Nkosi suggest so vividly. And, in the course of searching and sharpening, there were shifts of emphasis and direction, which in turn shaped the course of the CPSA’s history.
