The Don Republic ceased to exist after the Don Cossacks, who formed an essential part of the White Army, were defeated by the Red Army in the Russian Civil War. Many of the Russian Cossacks on Don were subjected to the Decossackization in 1919–1921, during the Soviet famine of 1932–33 and because of the repatriation of Cossacks after the Second World War by the United Kingdom to the Soviet Union, resulting in the eventual disappearance of the Don Cossacks' movement of resistance to the Soviet Union.
