Arbuzynka Raion

In the beginning of the 19th century, the current area of the district belonged to Yelisavetgradsky Uyezd of Kherson Governorate. In 1816, the areas of Konstantinovskaya and Blagodatnovskaya Volosts were made military settlements. In 1828, Yelisavetgradsky Uyezd was merged with Olviopolsky Uyezd into Bobrinetsky Uyezd. In 1857, military settlements were abolished. In 1865, the administrative center of Bobrinetsky Uyezd was moved to Yelisavetgrad, and the uyezd was renamed Yelisavetgradsky.[6] On 16 April 1920, Kherson Governorate was renamed Nikolayev Governorate, and on 21 October 1922, it was merged into Odessa Governorate. In 1923, uyezds in Ukrainian Soviet Socialist Republic were abolished, and the governorates were divided into okruhas. In 1925, the governorates were abolished, and okruhas were directly subordinated to Ukrainian SSR. In 1930, okruhas were abolished, and in 1931, Arbuzynka Raion, with the administrative center in Harbuzynka, was established. On 27 February 1932, Odessa Oblast was established, and Arbuzynka Raion was included into Odessa Oblast. In 1944, Arbuzynka Raion was transferred to Mykolaiv Oblast. In 1946, Harbuzynka was renamed Arbuzynka.[6] In January 1963, during the abortive Khrushchyov administrative reform, Arbuzynka Raion was abolished and split between Pervomaisk and Bratske Raions. In 1966, Arbuzynka Raion was re-established.[7] In 1967, Arbuzynka was granted urban-type settlement status.[6]

At the time of disestablishment, the raion consisted of two hromadas,[8]

• Arbuzynka settlement hromada with the administration in Arbuzynka;
• Blahodatne rural hromada with the administration in the selo of Blahodatne.
