The Bolsheviks initially consolidated control over most of the former empire. The Treaty of Brest-Litovsk was an emergency peace with the German Empire, who had captured vast swathes of the Russian territory during the chaos of the revolution. In May 1918, the Czechoslovak Legion in Russia revolted in Siberia. In reaction, the Allies began their North Russian and Siberian interventions. That, combined with the creation of the Provisional All-Russian Government, saw the reduction of Bolshevik-controlled territory to most of European Russia and parts of Central Asia. In 1919, the White Army launched several offensives from the east in March, the south in July, and west in October. The advances were later checked by the Eastern Front counteroffensive, the Southern Front counteroffensive, and the defeat of the Northwestern Army.
