Great Purge

The Great Purge (also called the Yezhovshchina, after NKVD chief Nikolai Yezhov) refers to the wave of political repression carried out in the Soviet Union under Joseph Stalin between approximately 1936 and 1938. It targeted Communist Party members, government officials, Red Army officers, intellectuals, peasants, ethnic minorities, and ordinary citizens accused of espionage, sabotage, or "counter-revolutionary" activity.

The purge is often dated from the assassination of Leningrad party boss Sergei Kirov in December 1934, which Stalin used as a pretext to expand state security powers. It escalated through three Moscow Show Trials (1936, 1937, 1938), at which prominent Old Bolsheviks — including Grigory Zinoviev, Lev Kamenev, Karl Radek, and Nikolai Bukharin — confessed to fabricated charges and were executed.

Key features included:

• NKVD Order No. 00447 (July 1937), which set regional quotas for arrests and executions of "anti-Soviet elements."
• The 1937 purge of the Red Army officer corps, which removed Marshal Mikhail Tukhachevsky and a large share of senior commanders, weakening Soviet readiness on the eve of WWII.
• National operations targeting Poles, Germans, Koreans, and other diaspora groups.
• Mass deportations to the Gulag camp system administered by the NKVD.

Estimates vary, but archival research by historians such as J. Arch Getty and Oleg Khlevniuk indicates that roughly 680,000–750,000 people were executed during 1937–38, with hundreds of thousands more dying in camps or exile. Yezhov himself was arrested in 1938, replaced by Lavrentiy Beria, and executed in 1940.

The Purge ended large-scale terror but not repression; Nikita Khrushchev publicly denounced Stalin's methods in his "Secret Speech" to the 20th Party Congress in February 1956, initiating a limited de-Stalinization. The Great Purge remains a central reference point in studies of totalitarianism, transitional justice, and the political logic of personalist dictatorships.
