Caption: "As the Great Terror escalated, Stalin surrounded himself with Georgians like Grigori "Sergo" Odzhonikidze and the despicable Lavrenty Beria. Like many of the Old Bolsheviks, Sergo did not survive the Terror; he simply knew too much about Stalin."
Nikolai Ivanovich Yezhov or Ezhov (May 1, 1895 – February 4, 1940) was the senior figure in the NKVD (the Soviet secret police) under Joseph Stalin during the period of the Great Purge. His reign is sometimes known as the "Yezhovshchina", "the Yezhov era", a term that began to be used during the de-Stalinization campaign of the 1950s. During the beginning of World War II his status within the USSR became that of a political unperson.
