Crimean Anschluss

In February and March 2014, Russia invaded and subsequently annexed the Crimean Peninsula from Ukraine. This event took place in the aftermath of the Revolution of Dignity and is part of the wider Russo-Ukrainian War.

The events in Kyiv that ousted Ukrainian president Viktor Yanukovych on 22 February 2014 sparked pro-Russian demonstrations as of 23 February against the (prospected) new Ukrainian government. At the same time Russian president Vladimir Putin discussed Ukrainian events with security service chiefs remarking that "we must start working on returning Crimea to Russia". On 27 February, Russian troops captured strategic sites across Crimea, followed by the installation of the pro-Russian Aksyonov government in Crimea, the Crimean status referendum and the declaration of Crimea's independence on 16 March 2014. Although Russia initially claimed their military was not involved in the events, Putin later admitted that troops were deployed to "stand behind Crimea's self-defence forces".
Russia formally incorporated Crimea on 18 March 2014.

Following the annexation, Russia escalated its military presence on the peninsula and made threats to solidify the new status quo on the ground.

Ukraine and many other countries condemned the annexation and consider it to be a violation of international law and Russian agreements safeguarding the territorial integrity of Ukraine. The annexation led to the other members of the then- G8 suspending Russia from the group and introducing sanctions. The United Nations General Assembly also rejected the referendum and annexation, adopting a resolution affirming the "territorial integrity of Ukraine within its internationally recognised borders", and referring to the Russian action as a "temporary occupation".

The Russian government opposes the "annexation" label, with Putin defending the referendum as complying with the principle of the self-determination of peoples.

Other names

In Ukraine

In Ukraine, annexation is known as the Temporary occupation of the Autonomous Republic of Crimea and Sevastopol by Russia ( uk, Тимчасова окупація Автономної Республіки Крим і Севастополя Росією, translit=Tymchasova okupatsiia Avtonomnoi Respubliky Krym i Sevastopolia Rosiieiu), the illegal occupation of the Autonomous Republic of Crimea, the fall of Crimea, and the invasion of Crimea.

In Russia

The names of the Crimean annexation vary. In Russia, it is known as the accession of Crimea to the Russian Federation (russian: Присоединение Крыма к Российской Федерации, translit=Prisoyedineniye Kryma k Rossiyskoy Federatsii), the return of Crimea (russian: Возвращение Крыма, translit=Vosvrashchenie Kryma), and the reunification of Crimea.

Background

Crimea was part of the Crimean Khanate from 1441 until it was annexed by the Russian Empire in 1783. After the end of the empire in the first stages of the Russian Civil War there were a series of short-lived independent governments ( Crimean People's Republic, Crimean Regional Government, Crimean SSR). They were followed by White Russian governments ( General Command of the Armed Forces of South Russia and later South Russian Government).

In October 1921, the Bolshevik Russian SFSR gained control of the peninsula and instituted the Crimean Autonomous Soviet Socialist Republic. Moscow joined the RSFSR with three other republics to form the Soviet Union the following year.

After the Second World War and the subsequent deportation of all of the indigenous Crimean Tatars, the Crimean ASSR was stripped of its autonomy in 1946 and downgraded to the status of an oblast of the Russian SFSR. In 1954, the Crimean Oblast was transferred from the Russian SFSR to the Ukrainian SSR by decree of the Presidium of the Supreme Soviet of the Soviet Union to commemorate the 300th anniversary of Ukraine's union with Russia. In 1989, under Gorbachev's perestroika, the Supreme Soviet declared that the deportation of the Crimean Tatars under Stalin had been illegal and the mostly Muslim ethnic group was allowed to return to Crimea.

In 1990, the Soviet of the Crimean Oblast proposed the restoration of the Crimean ASSR. The oblast conducted a referendum in 1991, which asked whether Crimea should be elevated into a signatory of the New Union Treaty (that is, become a union republic on its own). By that time, though, the dissolution of the Soviet Union was well underway. The Crimean ASSR was restored for less than a year as part of Soviet Ukraine before Ukrainian independence. Newly independent Ukraine maintained Crimea's autonomous status, while the Supreme Council of Crimea affirmed the peninsula's "sovereignty" as a part of Ukraine. Ukrainian authorities limited Crimean autonomy in 1995.}

During the 1990s, the dispute over control of the Black Sea Fleet and Crimean naval facilities were source of tensions between Russia and Ukraine. In 1992, Vladimir Lukin, then chairman of the Russian parliament's Committee on Foreign Affairs, suggested that in order to pressure Ukraine to give up its claim to the Black Sea Fleet, Russia should question Ukrainian control over Crimea. In 1998 the Partition Treaty divided the fleet and gave Russia a naval base in Sevastopol, and the Treaty of Friendship recognized the inviolability of existing borders. However, in 2003 Tuzla Island conflict issues over maritime border resurfaced.

In September 2008, the Ukrainian Foreign Minister Volodymyr Ohryzko accused Russia of giving Russian passports to the population in Crimea, and described it as a "real problem", given Russia's declared policy of military intervention abroad to protect Russian citizens.

On 24 August 2009, anti-Ukrainian demonstrations were held in Crimea by ethnic Russian residents. Sergei Tsekov (of the Russian Bloc and then deputy speaker of the Crimean parliament) said then that he hoped that Russia would treat Crimea the same way as it had treated South Ossetia and Abkhazia. Crimea is populated by an ethnic Russian majority and a minority of both ethnic Ukrainians and Crimean Tatars, and thus demographically possessed one of Ukraine's largest ethnically Russian populations.

As early as in 2010, some analysts already speculated that the Russian government had irredentist plans. Taras Kuzio said that "Russia has an even more impossible time recognizing Ukraine's sovereignty over the Crimea and the port of Sevastopol – as seen by public opinion in Russia, statements by politicians, including members of the ruling United Russia party, experts and journalists". In 2011, William Varettoni wrote that "Russia wants to annex Crimea and is merely waiting for the right opportunity, most likely under the pretense of defending Russian brethren abroad".

Euromaidan and the Revolution of dignity

The Euromaidan protest movement began in Kyiv in late November 2013 after President Viktor Yanukovych, of the Party of Regions, failed to sign the Ukraine–European Union Association Agreement due to failure of Ukrainian Supreme Council (Rada) to pass promised required legislation. Yanukovych won the 2010 presidential election with strong support from voters in the Autonomous Republic of Crimea and southern and eastern Ukraine. The Crimean autonomous government strongly supported Yanukovych and condemned the protests, saying they were "threatening political stability in the country". The Crimean autonomous parliament said that it supported the government's decision to suspend negotiations on the pending association agreement and urged Crimeans to "strengthen friendly ties with Russian regions".

On 4 February 2014, the Presidium of the Supreme Council considered holding a referendum on the peninsula's status, and asked the Russian government to guarantee the vote.The Chronicles of Alienation; The annexation of Crimea from 2 December 2013, through 4 April 2014
The Ukrainian Week (16 March 2015) The Security Service of Ukraine (SBU) responded by opening a criminal case to investigate the possible "subversion" of Ukraine's territorial integrity. On 20 February 2014, during a visit to Moscow, Chairman of the Supreme Council of Crimea Vladimir Konstantinov stated that the 1954 transfer of Crimea from the Russian Soviet Federative Socialist Republic to the Ukrainian Soviet Socialist Republic had been a mistake.

The Euromaidan protests came to a head in late February 2014, and Yanukovych and many of his ministers fled the capital on 22 February. After his flight, opposition parties and defectors from the Party of Regions put together a parliamentary quorum in the Verkhovna Rada (the Ukrainian parliament), and voted on 22 February to remove Yanukovych from his post on the grounds that he was unable to fulfill his duties, although this legislative removal lacked the required three-quarter vote of sitting Rada members according to the constitution in effect at the time, which the Rada also voted to suspend. Arseniy Yatsenyuk was appointed by the Rada to serve as the head of a caretaker government until new presidential and parliament elections could be held. This new government was recognised internationally, though the Russian government said that these events had been a " coup d'état" and that the caretaker government was illegitimate.

Annexation

Start of the crisis

The February 2014 revolution that ousted Ukrainian president Viktor Yanukovych sparked a political crisis in Crimea, which initially manifested as demonstrations against the new interim Ukrainian government,In Yalta was organized Euromaidan, in Sevastopol were demanding to imprison the opposition
19 February 2014 but rapidly escalated. In January 2014, the Sevastopol city council had already called for formation of "people's militia" units to "ensure firm defence" of the city from "extremism".

One of the initial Russian disinformation stories was the false allegation of a ''Corsun Pogrom'', which claimed that pro-Maidan Ukrainians stopped several busses with Anti-Maidan protesters on 20 February. Russian media sources described beating and humiliation among the protesters, while a fake news documentary claimed multiple tortured and killed people. No such event actually occurred and when human rights organizations tried to contact the producers of the documentary they found that no such organization existed. Human rights group attributed the fake story to "pro-Kremlin trolls".

The Verkhovna Rada of Crimea members called for an extraordinary meeting on 21 February. In response to Russian separatist sentiment, the Security Service of Ukraine (SBU) said that it would "use severe measures to prevent any action taken against diminishing the territorial integrity and sovereignty of Ukraine". The party with the largest number of seats in the Crimean parliament (80 of 100), the Party of Regions of Ukrainian president Viktor Yanukovych, did not discuss Crimean secession, and were supportive of an agreement between President Yanukovych and Euromaidan activists to end the unrest that was struck on the same day in Kyiv.

Russia was concerned that the new government avowedly committed to closer relations with the West put its strategic positions in Crimea at risk. On 22–23 February, Russian President Vladimir Putin convened an all-night meeting with security services chiefs to discuss extrication of the deposed Ukrainian president, Viktor Yanukovych, and at the end of that meeting Putin had remarked that "we must start working on returning Crimea to Russia". After that GRU and FSB began negotiating deals with local sympathizers to ensure that when the operation began there would be well‑armed "local self‑defense groups" on the streets for support. On 23 February, pro-Russian demonstrations were held in the Crimean city of Sevastopol.

Crimean prime minister Anatolii Mohyliov said that his government recognised the new provisional government in Kyiv, and that the Crimean autonomous government would carry out all laws passed by the Ukrainian parliament. In Simferopol, following a pro-Russian demonstration the previous day where protesters had replaced the Ukrainian flag over the parliament with a Russian flag, a pro-Euromaidan rally of between 5,000 and 15,000 was held in support of the new government, and demanding the resignation of the Crimean parliament; attendees waved Ukrainian, Tatar, and European Union flags. Meanwhile, in Sevastopol, thousands protested against the new Ukrainian government, voted to establish a parallel administration, and created civil defence squads with the support of the Russian Night Wolves motorcycle club. Protesters waved Russian flags, chanted "Putin is our president!" and said they would refuse to further pay taxes to the Ukrainian state. Russian military convoys were also alleged to be seen in the area.

In Kerch, pro-Russian protesters attempted to remove the Ukrainian flag from atop city hall and replace it with the flag of Russia. Over 200 attended, waving Russian, orange-and-black St. George, and the Russian Unity
