Nikolai Ivanovich Yezhov was a Soviet secret police official under Joseph Stalin who was head of the NKVD from 1936 to 1938, during the height of the Great Purge. Yezhov organized mass arrests, torture and executions during the Great Purge, but he fell from Stalin's favour and was arrested, subsequently admitting in a confession to a range of anti-Soviet activity including "unfounded arrests" during the Purge. He was executed in 1940 along with others who were blamed for the Purge.
