Reply #11: The Bolsheviks did not overthrow the Czarist regime in Russia...

That had already been accomplished in Feb/Mar 1917. The Bolsheviks ousted the provisional government of Alexander Kerensky in the Fall of 1917, which was primarily made up on anarchist factions. Then, the Bolsheviks carried out the executions of the Czar and his family, after they had been held in captivity for many months by the provisional government.

After the anarchists had been ousted, the Bolsheviks set up a secret police force to go after other factions on the LEFT in Russia -- the right had already been neutralized by this point.
