The revolt of the Czechoslovak Legion comprised the armed actions of the Czechoslovak Legion in the Russian Civil War against Bolshevik authorities, beginning in May 1918 and persisting through evacuation of the Legion from Siberia to Europe in 1920. The revolt, occurring in Volga, Ural, and Siberia regions along the Trans-Siberian Railway, was a reaction to a threat initiated by the Bolsheviks partly as a consequence of the Treaty of Brest-Litovsk. One major secondary consequence of victories by the Legion over the Bolsheviks was to catalyze anti-Bolshevik activity in Siberia, particularly of the Committee of Members of the Constituent Assembly, and to provide a major boost for the anti-Bolshevik or White forces, likely protracting the Russian Civil War.
