This volume collects the proceedings of the First Latin American Communist Conference, organized in Buenos Aires, Argentina in June 1929 by the South American Secretariat of the Moscow-based Communist International (Comintern). The Conference was the first and in some ways only opportunity that communists in Latin America had to engage in a broad discussion of the most important problems and challenges that they faced. The topics that the assembled delegates addressed – including militarism, anti-imperialism, trade union issues, and racial discrimination – were all central to the question of how to organise a strong revolutionary movement. This major documentary collection of the Latin American Communist movement, newly translated into English and with a substantial introduction, remains surprisingly relevant to our world today. With an introduction by Victor Jeifets and Lazar Jeifets.
