"The most important political vision was that of communist utopia. At war's end, it had been seventy years since Karl Marx and Friedrich Engels had penned their most famous lines: "Workers of the World Unite!" Marxism had inspired generations of revolutionaries with a summons to political and moral transformation: an end to capitalism and the conflict that private property was thought to bring, and it replacement that would liberate the working masses and restore all of humanity an unspoiled soul. Each dominant political order was challenged by new social groups formed by new economic techniques. The modern class struggle was between those who owned factories and those who worked in them. Accordingly, Marx and Engels anticipated that revolutions would begin in the more advanced industrial countries with large working classes, such as Germany and Great Britain. By disrupting the capitalist order and weakening the great empires, the First World War brought an obvious opportunity to revolutionaries. Most Marxists, however, had by then grown accustomed to working within national political systems, and chose to support their governments in time of war. Not so Vladimir Lenin, a subject of the Russian Empire and a leader of the Bolsheviks. His voluntarist understanding of Marxism, the belief that history could be pushed onto the proper track, led him to see the war as a great chance. For a voluntarist such as Lenin, assenting to the verdict of history gave Marxists a license to issue it themselves. Marx did not see history as fixed in advance but as the work of individuals aware of its principles. Lenin hailed from largely peasant country, which lacked, from a Marxist perspective, the economic conditions for revolution. Once again, he had a revolutionary theory to justify his revolutionary impulse. He believed that colonial empires had granted the capitalist system an extended lease on life, but that a war among empires could bring general revolution. The Russian Empire rumbled first, and Lenin made his move."
