We’ve looked at many battles in this series, but we’ve only tangentially touched on how this war fundamentally altered European society. The Great War is the watershed between the pre-modern and early modern era. As an example, all we have to do is look at Russia. Before World War One, it was an autocracy, very conservative, very religious, and only a few decades away from serfdom, which the rest of Europe abandoned in the Middle Ages. After the war, it was officially atheistic, communist, rapidly industrializing, and becoming one of two superpowers that dominated the 20th century. To Churchill, the Bolsheviks represented a greater threat to civilized Europe than did the reeking tube and iron shard of the Kaiser’s Reich. Bolshevism, he declared in the House of Commons, was “not a policy; it is a disease. It is not a creed; it is a pestilence.”
