From Cuba to Vietnam, from China to South Africa, the October Revolution inspired millions of people beyond the territory of Russia. The Revolution proved that the masses could not only overthrow autocratic governments, but also form an opposing government in their own image. The new idea that the working class and the peasantry could be allied, combined with the clear strength and necessity of a vanguard party, guided multiplying revolutions across the globe. This book explains the ideological power of the October Revolution in the Global South. From Ho Ch Minh to Fidel Castro, to reflections on polycentric Communism and collective memories of Communism, it shows how, for a brief moment, another world was possible. It is not a comprehensive study, but a small book with a large hope - that a new generation will come to see the importance of this revolutionary spirit for the working class and peasantry in the parts of the world that suffered under the heel of colonial domination for centuries.
