 "markdown": "# Kryve Ozero Raion\n\n**Kryve Ozero Raion** (Ukrainian: Кривоозерський район) was a former raion (district) of [Mykolaiv Oblast](https://www.edgepedia.org/mykolaiv-oblast), Ukraine, with its administrative center in the settlement of Kryve Ozero (Криве Озеро). Established in 1923, it existed until 17 July 2020, when it was abolished in a nationwide administrative reform and its territory merged into Pervomaisk Raion.\n\n| Key fact | Detail |\n|---|---|\n| Oblast changes | Included in Odesa Oblast on 27 February 1932; transferred to Mykolaiv Oblast in February 1954<sup>[7](https://esu.com.ua/pdf/file/342.pdf)</sup> |\n| Population | 24,122 (GeoNames estimate for the historical division)<sup>[1](https://www.geonames.org/search.html?country=UA&q=Nikolaev)</sup> |\n| Abolished | 17 July 2020, merged into Pervomaisk Raion; Mykolaiv Oblast's raions were reduced to four<sup>[8](https://www.rada.gov.ua/news/novyny/196122.html)</sup> |\n| Successor community | Kryvoozerska settlement community, area 814.43 km², 27 settlements, 15 starosta districts<sup>[2](https://hromada.gov.ua/community/mk/kryvoozerska_selyschna_hromada_pervomajskij_rn)</sup> |\n\n## Establishment and early history\n\nIn 1925 the governorates were abolished and the okruhas were directly subordinated to the Ukrainian SSR, and in 1930 the okruhas were abolished in turn.\n\nIn February 1954 the raion was transferred to Mykolaiv Oblast, within which it remained for the rest of its existence<sup>[7](https://esu.com.ua/pdf/file/342.pdf)</sup>.\n\n## The administrative center\n\nKryve 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 channels<sup>[3](https://esu.com.ua/article-1967)</sup>. The Encyclopedia of Modern Ukraine records 8,577 inhabitants in 2001, mostly [Ukrainians](https://www.edgepedia.org/ukrainians) with a Russian minority, and notes that the Kyiv–Odesa highway passes near the settlement<sup>[3](https://esu.com.ua/article-1967)</sup>.\n\n## Abolition in the 2020 reform\n\nOn 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](https://www.edgepedia.org/autonomous-republic-of-crimea) and the oblasts and liquidated all raions existing under the previous subdivision<sup>[4](https://www.rada.gov.ua/print/196122.html)</sup>. Under the reform, raion boundaries were set along the outer limits of the rural, settlement, and city territorial communities included in each raion<sup>[4](https://www.rada.gov.ua/print/196122.html)</sup>.\n\nThe new Pervomaisk Raion, with its center in the city of Pervomaisk, was formed from eight territorial communities, including the Kryvoozerska settlement community<sup>[5](https://www.mk-oblrada.gov.ua/news.php?group=20&news=2359)</sup>.\n\n## Successor community\n\nThe Kryvoozerska settlement community, centered on Kryve Ozero, now forms part of [Pervomaiskyi Raion](https://www.edgepedia.org/pervomaiskyi-raion). It covers 814.43 km² and contains 27 settlements organized into 15 starosta districts (starostynski okruhy)<sup>[2](https://hromada.gov.ua/community/mk/kryvoozerska_selyschna_hromada_pervomajskij_rn)</sup>. A 2022 MapAction map of Mykolaiv Oblast shows Kryve Ozero within the enlarged Pervomaiskyi Raion (UA4808) in the northwest of the oblast<sup>[6](https://maps.mapaction.org/dataset/b014200f-377a-4760-a297-f2cdd38fdcf3/resource/1b608fe6-4d1a-444c-bf58-bd6da85544d9/download/ma004-v01-ukr-oblast-map-series-atlas.pdf)</sup>.\n\n## References\n\n1.
