On 16 April 1920,
Odessa Governorate was established. Domanivka was the center of
Domanivskaya Volost and belonged to
Voznesensky Uyezd of
Kherson Governorate. In 1923,
uyezds in
Ukrainian Soviet Socialist Republic were abolished, and the governorates were divided into
okruhas. In 1923, Kantakuzynka Raion with the administrative center in the
selo of
Kantakuzynka was established, and Domanivka became the part of the raion. It belonged to
Pervomaisk Okruha. In 1925, the governorates were abolished, and okruhas were directly subordinated to Ukrainian SSR. On 3 February 1926, Katakuzynka Raion was renamed
Domanivka Raion, and the center was moved to Domanivka. Many thousands of them were from Odessa. A minority of the Jews who were killed were Bessarabian Jews. The victims were killed, mainly by the Romanian constabulary, the Romanian army supported by Ukrainian militia and the
Sonderkommando. After the occupation of Transnistria by the Germans in World War II, and under Ion Antonescu, the ruler of Romania in October 1941, an extermination camp was established in Domanovka, where thousands of Jews were murdered. The camp was liberated on March 28, 1944, by the Red Army. According to Jean Ancel, "about five hundred Jews were still alive, mostly expellees from Romania." Among the main perpetrators of crime in Transnistria were the Romanian army and police. Their actions stemmed from their political support for Germany and the Nazis during World War II. The Romanian policy in the Transnistria camp carried through starvation, forced camps, mass shootings, and more. For more information on the Holocaust in
Transnistria, including on the fate of the Jewish deportees from Romania, including Bessarabia, see
History of the Jews in Transnistria. In February 1954, Domanivka Raion was transferred to Mykolaiv Oblast. In 1956, Domanivka was granted
urban-type settlement status. On 18 July 2020, Domanivka Raion was abolished as part of the administrative reform of Ukraine, which reduced the number of raions of Mykolaiv Oblast to four. The area of Domanivka Raion was merged into Voznesensk Raion. On 26 January 2024, a new law entered into force which abolished the status of urban-type settlement status, and Domanivka became a rural settlement. ==Economy==
