Declaration of Independence of the Republic of Crimea in the context of "Republic of Crimea (country)"

In February and March 2014, Russia invaded the Crimean Peninsula, part of Ukraine, and then annexed it. This took place in the relative power vacuum immediately following the Revolution of Dignity. It marked the beginning of the Russo-Ukrainian War.

The events in Kyiv that ousted Ukrainian president Viktor Yanukovych on 22 February 2014 sparked both pro-Russian and anti-separatism demonstrations in Crimea. At the same time, Russian president Vladimir Putin told his security chiefs to begin work on "returning Crimea to Russia". On 27 February, Russian special forces without insignia seized strategic sites across Crimea. Russia at first denied involvement, but Putin later admitted that they were Russian troops. As the armed men occupied Crimea's parliament, it dismissed the Crimean government, installed the pro-Russian Aksyonov government, and announced a referendum on Crimea's status. The referendum was held under Russian occupation and, according to the Russian-installed authorities, the result was overwhelmingly in favor of joining Russia. The next day, 17 March 2014, Crimea's authorities declared independence and requested to join Russia. Russia formally incorporated Crimea on 18 March 2014 as the Republic of Crimea and federal city of Sevastopol. Following the annexation, Russia militarized the peninsula and warned against any outside intervention.

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.
