Mykolaiv Raion, Mykolaiv Oblast

In the 19th century, the area belonged to Kherson Governorate. In December 1920, it was renamed Nikolayev Governorate, and in 1921 it was merged into Odessa Governorate. In 1923, governorates were abolished in the Ukrainian Soviet Socialist Republic. In 1923, Mykolaiv Raion of Mykolaiv Okruha, with the administrative center in Mykolaiv, was established. The city of Mykolaiv belonged to the raion. In 1925, the governorates were abolished, and okruhas were directly subordinated to Ukrainian SSR. In 1930, okruhas were abolished, and Mykolaiv Raion was abolished.[2] The area was transferred to Varvarivka Raion.[3] On 27 February 1932, Odessa Oblast was established, and the area was transferred to Odessa Oblast. On 22 September 1937, Mykolaiv Oblast was established on lands which previously belonged to Dnipropetrovsk and Odessa Oblasts, and Varvarivka Raion became part of newly created Mykolaiv Oblast. On 8 August 1945, Shyrokolanivka Raion was established on the area which previously belonged to Varvarivka and Tylihulo-Berezanka Raions. The area thus became split between Varvarivka and Shyrokyi Lan Raions. On 7 June 1957, Shyrokyi Lan Raion was abolished, and split between Varvarivka and Veselynove Raions. In January 1963, Varvarivka Raion was abolished, and Mykolaiv Raion was re-established.[4]

On 18 July 2020, as part of the administrative reform of Ukraine, the number of raions of Mykolaiv Oblast was reduced to four, and the area of Mykolaiv Raion was significantly expanded. [5][6] In 2001, population of the district was 34,675. The January 2020 estimate of the raion population was 29,389 (2020 est.)[7]
