Abstract

The Bolshevik Revolution was the most important event of the twentieth century. It radically transformed Russia and the other nations that made up the Great Russian Empire. Lenin and Trotsky, together with a plethora of revolutionary intellectuals and leaders of the workers’ movement, led the process of seizing power. Under extremely adverse conditions, they consolidated the Revolution, giving practical solution to many crucial and unpublished problems they faced, which from circumstantial situations, were elevated to the category of theories that became the ideas/guides of a large part of the communist movement to this day. With Stalin´s triumph and his group, the idea of socialism was imposed in one country, establishing a socialist model based on the dictatorship of the single party. The USSR was decisive in the defeat of Nazism, consolidating itself as a great power and with great conquests for its population. It lost the economic battle with capitalism, collapsing tragically.
