What caused the Russian revolution?

Nineteen seventeen is a year that resonated through the 20th century. But place matters here as much as time – “place” meaning not just Russia, but Petrograd, as the imperial capital became known after “St Petersburg” was de-Germanised on the outbreak of war in 1914. Though in due course 1917 was touted as a universal model for revolution, it cannot be detached from the impact of the Great War in a distinctive country and a uniquely combustible city. Nor can it be separated from the intertwined stories of two almost incomprehensible men, a failed autocrat and a ruthless dictator: Tsar Nicholas II and Vladimir Lenin, Russia’s Terrible Twins.

The Great War may as well have been called the Great Killing. In 1916, the London Annual Register offered this elegant summary of the callous calculus that passed for Grand Strategy: “[T]he number of men possessed by the Entente Powers was much greater than the number that the Central Powers could command. The war was therefore to be a crude process of sheer killing. And then, assuming that each side killed equally effectively, the Entente would reach victory in an inevitable manner through the working of a simple mathematical law.”

But each side did not kill “equally effectively”. Not only were the Germans more efficient killers than their opponents, but the homicidal potency of each country on the battle front depended on its industrial efficiency on the home front. Despite frequent strikes, Britain and France “worked” as societies and economies; the main member of the Entente, Russia, did not.
