Treaty of Brest-Litovsk

Not to be confused with the Treaty of Brest-Litovsk (Ukraine–Central Powers), a similar treaty involving Ukraine and the Central Powers.

The Treaty of Brest-Litovsk was a peace treaty signed on 3 March 1918 between the new Bolshevik government of Soviet Russia and the Central Powers (Germany, Austria-Hungary, Bulgaria, and the Ottoman Empire), that ended Russia's participation in World War I. The treaty was signed at Brest-Litovsk (Polish: Brześć Litewski; since 1945 Brest), after two months of negotiations. The treaty was forced on the Bolshevik government by the threat of further advances by German and Austrian forces. According to the treaty, Soviet Russia defaulted on all of Imperial Russia's commitments to the Triple Entente alliance.

The newly established Soviet government decided to end Russia's participation in the war with Germany and its allies. On 26 October 1917, Vladimir Lenin signed the Decree on Peace, which was approved by the Second Congress of the Soviet of Workers', Soldiers', and Peasants' Deputies. 
                                           
The Decree called "upon all the belligerent nations and their governments to start immediate negotiations for peace" and proposed an immediate withdrawal of Russia from World War I. 

Leon Trotsky was appointed Commissar of Foreign Affairs in the new Bolshevik government. In preparation for peace talks with the representatives of the German government and the representatives of the other Central Powers, Leon Trotsky appointed his good friend, Adolph Joffe, to represent the Bolsheviks at the peace conference.

Lenin never forgot this Agreement, because Lenin felt that he was forced sign this agreement. Especially Finland was a difficult piece to Lenin.

On the other hand, he also received asylum in Finland, where he could be hiding in the Tsar's men, and go back to Russia, when it was safe. And again, Lenin idea was to set up a Russian firsts punishment camps, and Lenin orders (about) 3,5 million people died or executed. He is the fourth or fifth killing of the top name, in 1900's
