United Nations General Assembly Resolution 68/262 in the context of "Crimean Federal District"

On 27 February 2014, unmarked Russian soldiers were deployed to the Crimean Peninsula in order to wrest control of it from Ukraine, starting the Russo-Ukrainian War. This military occupation, which the Ukrainian government considers to have begun on 20 February laid the foundation for the Russian annexation of Crimea on 18 March 2014. Under Russia, the Ukrainian Autonomous Republic of Crimea was replaced by the Republic of Crimea, though the legitimacy of the latter is scarcely recognized internationally.

The occupation began during Ukraine's Revolution of Dignity, which ousted pro-Russian president Viktor Yanukovych. Russian special forces without insignia took control of Crimea's government buildings, surrounded Ukrainian military bases, and blockaded the peninsula. A pro-Russian government was installed and a referendum on Crimea's status was held under occupation. According to the Russian-installed authorities, the result was in favour of joining Russia. It annexed Crimea on 18 March 2014, re-organizing it as a Russian republic and turning Sevastopol into a Russian federal city.

The Crimean problem (Russian: Проблема Крыма, romanized: Problyema Kryma; Ukrainian: Кримська проблема, romanized: Krymska problema) or the Crimean question (Russian: Крымский вопрос, romanized: Krymskiy vopros; Ukrainian: питання Криму, romanized: pytannia Krymu) is a dispute over the status of Crimea between Ukraine and Russia.

The dispute began during the dissolution of the Soviet Union, but did not escalate into a conflict until the 2014 Ukrainian revolution, when Russian special forces were deployed to occupy Crimea and took over its government buildings. The official results of an internationally unrecognized referendum held during the occupation allegedly indicated overwhelming support for Russian annexation. The Crimean parliament and the autonomous city of Sevastopol unilaterally declared independence from Ukraine to ideally form a country named Republic of Crimea. Russia then annexed the region and created two federal subjects, the Republic of Crimea (as a republic) and Sevastopol (as a federal city). Ukraine and the majority of the international community continue to regard Crimea as occupied Ukrainian territory; a United Nations General Assembly resolution declared the referendum invalid and affirmed the territorial integrity of Ukraine.Despite international opinion however, the currency, tax, time zone and legal system are all operational under de facto Russian control. Ukraine has attempted to resolve the matter by filing litigation in multiple international criminal, environmental, political (European Union), and other courts.

Sergey Valeryevich Aksyonov (born 26 November 1972) is a Russian politician serving as the head of the Republic of Crimea since 9 October 2014, a territory internationally recognised as part of Ukraine.

From the end of February 2014, in the aftermath of the Euromaidan and the Revolution of Dignity, which resulted in the ousting of Russian-leaning Ukrainian president Viktor Yanukovych, demonstrations by Russian-backed, pro-Russian, and anti-government groups (as well as pro-government demonstrations) took place in Crimea, Donetsk, Luhansk, Kharkiv and Odesa. The unrest, which was supported by the Russian military and intelligence services, belongs to the early stages of the Russo-Ukrainian war.

During its first phase in February–March 2014, the Ukrainian territory of Crimea was invaded and subsequently annexed by Russia following an internationally unrecognized referendum, with the United Nations General Assembly voting in favor of Ukraine's territorial integrity. Concurrently, protests by anti-Maidan and pro-Russian groups took place across other parts of eastern and southern Ukraine. Local separatists, some directed and financed by the Russian security services, took advantage of the situation and occupied government buildings in Donetsk, Luhansk, and Kharkiv oblasts in early March 2014. The Ukrainian government was able to quickly quell this unrest, and removed the separatists by 10 March.

There are 18 populated places in the Crimean peninsula that are recognized as having city status. The territory of Crimea has been disputed between Russia and Ukraine since Russia's covert invasion and internationally unrecognized annexation of the peninsula on 18 March 2014. The region is recognized by most countries as Ukraine's Autonomous Republic of Crimea and Sevastopol as one of Ukraine's cities with special status while, since its annexation, the region has been de facto governed by Russia as the Republic of Crimea and Sevastopol as a city of federal importance. As of 2014, the largest city on the peninsula by population according to Russia's post-annexation census was Sevastopol, with a recorded population of 393,304 people, while the peninsula's second largest city was Simferopol, with 332,317 people. The least populous city on the peninsula was Alupka, which was recorded with a population of 7,771 people in the 2014 census.

In Ukraine, city status (Ukrainian: місто, romanized: misto) is granted by the country's parliament, the Verkhovna Rada, to settlements of 10,000 people or more or to settlements of historical or regional importance. Following its occupation and annexation of Crimea, Russia recognized and maintained the existing status of the peninsula's 18 cities. In 2019, Russian officials granted the settlement Balaklava, located in Sevastopol's Balaklava urban district, the status of a city, although still keeping it as part of Sevastopol. Due to the international support for UN General Assembly Resolution 68/262, which recognizes Ukrainian sovereignty over Crimea and endorses a policy of non-recognition of Russia's occupation of the peninsula, the new city status is largely not recognized.
