It was largely the same groups of individuals who were responsible for the mass killing operations during the civil war, collectivization, and the Great Terror. These groups were associated with Efim Georgievich Evdokimov (1891-1939) and operated in Ukraine during the civil war, in the North Caucasus in the 1920s, and in the Secret Operational Division within General State Political Administration (OGPU) in 1929-31. Evdokimov transferred into Communist Party administration in 1934, when he became Party secretary for North Caucasus Krai. But he appears to have continued advising Joseph Stalin and Nikolai Yezhov on security matters, and the latter relied on Evdokimov's former colleagues to carry out the mass killing operations that are known as the Great Terror in 1937-38.<ref>Stephen G.
