The Red Terror was a campaign of political repression and executions in Soviet Russia which was carried out by the Bolsheviks during the Russian Civil War, chiefly through the Cheka, the Bolshevik secret police force. It officially started in early September 1918 and it lasted until 1922, though violence committed by Bolshevik soldiers, sailors, and Red Guards had been ongoing since late 1917.
Decreed after assassination attempts on Vladimir Lenin along with the successful assassinations of Petrograd Cheka leader Moisei Uritsky and party editor V. Volodarsky in alleged retaliation for Bolshevik mass repressions, the Red Terror was modeled on the Reign of Terror of the French Revolution, and the Paris Commune.
