De-Cossackization (Russian: Расказачивание, romanized: Raskazachivaniye) was the Bolshevik policy of systematic repression against the Cossacks in the former Russian Empire between 1919 and 1933, especially the Don and Kuban Cossacks in Russia, aimed at the elimination of the Cossacks as a distinct collectivity by exterminating the Cossack elite, coercing all other Cossacks into compliance, and eliminating Cossack distinctness.[5] Several scholars have categorised this as a form of genocide,[6][7][8][9][10] whilst other historians have highly disputed this classification due to the contentious figures which range from "a few thousand to incredible claims of hundreds of thousands".[11][12][13]
The campaign began in March 1919 in response to growing Cossack insurgency.[5] According to Nicolas Werth, one of the authors of The Black Book of Communism, Soviet leaders deciding to "eliminate, exterminate, and deport the population of a whole territory", which they had taken to calling the "Soviet Vendée".[14] The process has been described by scholar Peter Holquist as part of a "ruthless" and "radical attempt to eliminate undesirable social groups" that showed the Soviet regime's "dedication to social engineering".[15][1] Throughout this period, the policy underwent significant modifications, which resulted in the "normalization" of Cossacks as a component part of Soviet society.[1]
^"The socio-demographic statistical data for the period of the late 1920s summarized by the quota (local) representative sample and attracted by the article indicate the absence of negative population dynamics, including the Cossack population, which leads to the conclusion that the red power did not use terror and genocide against the Cossacks massively in the designated period of time, and, accordingly, the Bolsheviks did not carry out a large-scale decossackization policy."Skorik, Alexander.

^"Thus, one of the most famous manifestations of the Red Terror is the policy of “decossackization” on the Don in 1919. The number of its victims is estimated differently, up to tens and even hundreds of thousands of people, sometimes it is even defined as “genocide.” Recently, Cossack researcher A.V. paid attention to this issue. Venkov in a book about the Veshensky uprising, and he mainly relied on data from the rebels. As it turned out, both sides at the height of the conflict agreed that about 300 people were killed by the Reds before the uprising".Zayats, Nikolay.
