What term did Fitzpatrick use to describe the CHEKA?

Fitzpatrick referred to the CHEKA as an "Organ of Terror" to emphasize its role as the primary security and secret police force established by the Bolsheviks during the Russian Revolution. This designation reflects the CHEKA's function in suppressing dissent, instilling fear, and carrying out harsh punitive measures against perceived enemies of the state. The CHEKA was instrumental in enforcing the Bolshevik regime's authority through acts of violence and intimidation, which were key strategies during the Civil War and the early years of Soviet power. The term captures the essence of the organization as a tool of political repression and state-sponsored violence, highlighting its significance in maintaining the revolutionary government's control over the population.
