Establishment and early history
In 1925 the governorates were abolished and the okruhas were directly subordinated to the Ukrainian SSR, and in 1930 the okruhas were abolished in turn.
In February 1954 the raion was transferred to Mykolaiv Oblast, within which it remained for the rest of its existence7.
The administrative center
Kryve Ozero lies on the banks of the Kodyma River and was founded in 1762, taking its name from a lake with uneven, winding shores formed by joined river channels3. The Encyclopedia of Modern Ukraine records 8,577 inhabitants in 2001, mostly Ukrainians with a Russian minority, and notes that the Kyiv–Odesa highway passes near the settlement3.
Abolition in the 2020 reform
On 17 July 2020 the Verkhovna Rada of Ukraine adopted the resolution "On the Formation and Liquidation of Raions", which created 136 new raions in the Autonomous Republic of Crimea and the oblasts and liquidated all raions existing under the previous subdivision4. Under the reform, raion boundaries were set along the outer limits of the rural, settlement, and city territorial communities included in each raion4.
The new Pervomaisk Raion, with its center in the city of Pervomaisk, was formed from eight territorial communities, including the Kryvoozerska settlement community5.
Successor community
The Kryvoozerska settlement community, centered on Kryve Ozero, now forms part of Pervomaiskyi Raion. It covers 814.43 km² and contains 27 settlements organized into 15 starosta districts (starostynski okruhy)2. A 2022 MapAction map of Mykolaiv Oblast shows Kryve Ozero within the enlarged Pervomaiskyi Raion (UA4808) in the northwest of the oblast6.
