Russia’s disastrous involvement in World War I was a primary factor that led to Vladimir Lenin’s successful Marxist revolution in November 1917. In December 1917, Germany agreed to an armistice and peace talks with Russia, and Lenin sent Leon Trotsky to Brest-Litovsk in Belarus to negotiate a treaty. The talks broke off after Germany demanded independence for Russian holdings in Eastern Europe, and in February 1918 fighting resumed on the eastern front. With German troops advancing on St. Petersburg, Lenin authorized the signing of the Treaty of Brest-Litovsk on March 3, 1918.
