While he was in exile for spreading Marxist ideas with his wife around Russia, Germany, while still in the war against Russia, helped this revolutionary leader corrupt Russia. Shortly after, the Bolsheviks, with returning leader Lenin, fought in squads of Red Guards against the Whites at the Winter Palace where the provisional gov. was holding a meeting. Under Lenin, Russia signed the Brist-Litosvsk Treaty with Russia to end the war. During the civil war, troops from the Allies came in to fight against the Whites. Then, after many counterrevolutionaries attempted to assassin Lenin, the Communists, with their capital in Moscow, launched a reign of terror. They organized the Cheka, secret police, and executed ordinary citizens with tiny suspicions of going against revolution. Lenin and his followers then proceeded to kill the czar and his children to take away the symbol of will for the Whites. Lenin than enforced war communism.
