The Russian Revolution is the collective term for the two revolutions that took place in 1917 in Petrograd. The February Revolution overthrew the Tsar, and the October Revolution put the radical left-wing Bolsheviks in power.
The Russian Civil War, that followed the Bolshevik coup, caused more casualties than World War I. It was the bloodiest military conflict ever to take place on Russian soil. The extremely brutal, “Red Terror,” was opposed to the equally ruthless, “White Terror”.
