This episode of Ten Minute History (like a documentary, only shorter) covers the late Russian Empire under Tsar Nicholas II all the way to the USSR just before World War II. The first part of the Episode covers the social and political issues and changes until the February Revolution. The second part covers the October Revolution and how Lenin, Trotsky and Stalin established the Soviet Union and how things changed. Without a doubt, the Russian Revolution was one of (if not the) most important event of the 20th century.
