During the first two months of 1917 Russia was still a Romanov monarchy. Eight months later the Bolsheviks stood at the helm. They were little known to anybody when the year began, and their leaders were still under indictment for state treason when they came to power. You will not find another such sharp turn in history especially if you remember that it involves a nation of 150 million people. It is clear that the events of 1917, whatever you think of them, deserve study.
