How did the Bolsheviks gain and keep power after the Russian Revolution?

The Bolsheviks gained and maintained power through a combination of strategic maneuvering, the suppression of political opposition, and the consolidation of state control.

Gaining Power

In October 1917, the Bolsheviks executed a coup d’état led by a small group of conspirators. They utilized the Military Revolutionary Committee—originally formed for Petrograd's defense—to seize strategic points in the city. By leveraging their control over the Red Guards and promising "peace, land, and bread," they effectively toppled the provisional government.1

Maintaining Power

Once in control, the Bolsheviks systematically dismantled democratic processes to ensure their dominance:

• Suppression of Dissent: After losing the 1917 Constituent Assembly elections, the Bolsheviks forcibly dissolved the assembly in January 1918. They subsequently outlawed rival political parties and suppressed non-Bolshevik media.2
• Secret Police: The Cheka was established to eliminate "counterrevolutionaries" through arrests and executions, providing the regime with a ruthless tool for internal security.23
• Centralized Control: The Bolsheviks concentrated power within the Politburo and other party organs, ensuring that state institutions merely rubber-stamped party decisions.2
• Military Victory: During the Russian Civil War, the Red Army, led by Leon Trotsky, defeated the anti-communist "White" forces, allowing the party to consolidate control over the industrial heartland.4
