The Great Purge was a campaign of political repression in the Soviet Union during the late 1930s, led by Joseph Stalin. It aimed to eliminate dissent and consolidate Stalin's power by targeting perceived enemies within the Communist Party, military, and society. Thousands of people were arrested, executed, or sent to labor camps, creating a climate of fear and suspicion. During this time, many prominent figures, including military leaders and party officials, were purged. The NKVD, the secret police, played a crucial role in carrying out these arrests. The Great Purge significantly impacted Soviet society, leading to a loss of intellectual and military talent that would affect the country for years to come.
