Pervomaisk Raion

In the beginning of the 19th century, the current area of the district belonged to Olviopolsky Uyezd of Kherson Governorate. In 1828, Olviopolsky Uyezd was merged with Yelisavetgradsky Uyezd into Bobrinetsky Uyezd. In 1865, the administrative center of Bobrinetsky Uyezd was moved to Yelisavetgrad, and the uyezd was renamed Yelisavetgradsky.{{cite web|url=http://www.ngorod.net.ua/history/fragmenty-istorii-arbuzinskogo-rajona/|title=Фрагменты истории Арбузинского района|publisher=Новый Город|language=Russian|accessdate=4 March 2016}} In 1919, Olviopol was merged with Bohopil and Holta to form the city of Pervomaisk.{{cite web|url=http://pervomaisk.mk.ua/userfiles/%D0%AD%D0%BA%D1%81%D0%BA%D1%83%D1%80%D1%81%D0%B8%D1%8F_%D0%BF%D0%BE_%D1%86%D0%B5%D0%BD%D1%82%D1%80%D1%83_%D0%B3%D0%BE%D1%80%D0%BE%D0%B4%D0%B0.pdf|title=Пешеходный экскурсионный маршрут по центральной части г.Первомайска|publisher=City of Pervomaisk|language=Russian|accessdate=17 March 2016}} On 16 April 1920, Kherson Governorate was renamed Nikolayev Governorate, and on 21 October 1922, it was merged into Odesa Governorate. In 1923, uyezds in Ukrainian Soviet Socialist Republic were abolished, and the governorates were divided into okruhas. Bohopil Raion of Pervomaisk Okruha was established.

In 1930, okruhas were abolished, and raions were directly subordinated to Ukrainian SSR. On 27 February 1932, Odesa Oblast was established, and Pervomaisk Raion was included into Odesa Oblast.
