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.
