policy-related factors, like the drought of 1931 and poor weather in 1932; inadvertent result of policies with other objectives, like rapid industrialization, socialization of livestock, and neglected crop rotation patterns; and deaths caused intentionally by a starvation policy. The Communist leadership perceived famine not as a humanitarian catastrophe but as a means of class struggle and used starvation as a punishment tool to force peasants into collective farms. It was largely the same groups of individuals who were responsible for the mass killing operations during the civil war, collectivisation, 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.
With Joseph Stalin's change of course in the late 1920s, however, Moscow's toleration of Ukrainian national identity came to an end. Systematic state terror of the 1930s destroyed Ukraine's writers, artists, and intellectuals; the Communist Party of Ukraine was purged of its "nationalist deviationists". Two waves of Stalinist political repression and persecution in the Soviet Union (1929–34 and 1936–38) resulted in the killing of some 681,692 people; this included four-fifths of the Ukrainian cultural elite and three-quarters of all the Red Army's higher-ranking officers.

Following the Invasion of Poland in September 1939, German and Soviet troops divided the territory of Poland. Thus,
