Arising after assassination attempts on Vladimir Lenin and Petrograd Cheka leader Moisei Uritsky in retaliation for Bolshevik atrocities, the latter of which was successful, the Red Terror was modeled on the Reign of Terror of the French Revolution, and sought to eliminate political dissent, opposition, and any other threat to Bolshevik power.

Allied intervention in the Russian Civil WarThe Allied intervention in the Russian Civil War consisted of a series of multi-national military expeditions that began in 1918. The initial impetus behind the interventions was to secure munitions and supply depots from falling into the German Empire's hands, particularly after the Bolsheviks signed the Treaty of Brest Litovsk, and to rescue the Allied forces that had become trapped within Russia after the 1917 October Revolution. After the Armistice of 11 November 1918, the Allied plan changed to helping the White forces in the Russian Civil War.
