Vladimir Lenin
In 1917, The Kadets, a right-wing party, and elements of the Okhrana (secret police) started rumors that Lenin had got money from the Germans, because they had sent him through Germany in a special train to reach Russia. That may have made him look bad because a lot of Russians had died fighting Germany in the war. After the July Days, a popular uprising in Petrograd which was crushed by the Russian Provisional Government, he left Russia and went to Finland, where he could hide and carry on with his work on Communism.
