Timeline of the annexation of Crimea by the Russian Federation

The annexation of Crimea by the Russian Federation took place in the aftermath of the 2014 Ukrainian revolution. On 22–23 February, Russian President Vladimir Putin convened an all-night meeting with security services chiefs to discuss pullout of deposed President, Viktor Yanukovych, and at the end of that meeting Putin remarked that "we must start working on returning Crimea to Russia.". Russia sent in soldiers on February 27, 2014. Crimea held a referendum. According to official Russian and Crimean sources 95% voted to reunite with Russia. The legitimacy of the referendum has been questioned by the international community on both legal and procedural grounds.

February 2014

February 19

Members of the Sevastopol City Council petitioned to President Viktor Yanukovych to take stringent measures and bring leaders of the opposition to justice. "Leaders of opposition should be held criminally liable for inciting armed confrontation," – stated the declaration. In Simferopol, activists of "Stop Maidan" were commemorating Crimean law enforcement agents who perished in conflict in Kyiv. In Yalta, over 50 activists attended an anti-government protest and demonstrated support for Euromaidan.

February 20

Speaker of the Supreme Council of Crimea, Vladimir Konstantinov announced that he does not exclude possibility of secession of Crimea from Ukraine if the situation in the country worsens. The head of Mejlis of the Crimean Tatar People Refat Chubarov criticized the announcement and said that Konstantinov who was in Moscow at the time, openly invited Russian security forces to intervene in Crimean internal politics.

The Russian military operation against Ukraine started on this date, according to the inscription on the Medal "For the Return of Crimea", awarded by the Russian Ministry of Defence. A Ukrainian law signed September 2015 designated this as the "date of the start of the temporary occupation".

February 23

In Simferopol, a pro-Euromaidan rally was held in support of the new Ukrainian authorities. The protesters also demanded the resignation of the Crimean parliament and waved Ukrainian, Tatar, and European Union flags. The Prime Minister of Crimea Anatolii Mohyliov declared that the region would carry out all laws passed by the Ukrainian parliament.

Meanwhile in Sevastopol, tens of thousands protested against the new authorities and voted to establish a parallel administration and civil self-defense squads. Some were created on 22 February in Simferopol, where about 5,000 people joined such squads. Protesters waved Russian flags and chanted "Putin is our president" and claimed they would refuse to pay further taxes to the 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 flags of Russia, orange-and-black St. George and the Russian Unity party. Mayor Oleh Osadchy attempted to disperse the crowd and police eventually arrived to keep the protesters at bay. Osadchy said: "This is the territory of Ukraine, Crimea. Here's a flag of Crimea" but was accused of treason and a fight ensued over the flagpole.

February 24

More protesters rallied outside the Sevastopol administration offices. Pro-Russian demonstrators accompanied by neo-Cossacks demanded the selection of a Russian citizen as mayor (which was refused by the city council) and planted Russian flags at city hall; they also handed out leaflets calling for volunteers to a militia and warning that the "Blue-Brown Europlague is knocking."

On 24 February, a pro-Russian rally in Sevastopol chose Aleksei Chalyi, a Russian citizen, as mayor. This was controversial because Sevastopol has no mayor as the Chairman of the Sevastopol City State Administration (Governor of Sevastopol) who is appointed by the President of Ukraine by statute fulfils this role. A thousand protesters present chanted "a Russian mayor for a Russian city." Crowds gathered again outside Sevastopol's city hall again as rumours spread that security forces could arrest Aleksei Chalyi, but police chief Alexander Goncharov said that his officers would refuse to carry out "criminal orders" issued by the central government. Viktor Neganov, a Sevastopol-based adviser to the interior minister, condemned the events in the city as a coup. "Chalyi represents the interests of the Kremlin which likely gave its tacit approval." The Chairman of the Sevastopol City State Administration, appointed by the President of Ukraine, Vladimir Yatsuba, was booed and whistled on February 23, when he told a pro-Russian rally that Crimea was a part of Ukraine. He resigned the next day.

February 25

Several hundred pro-Russian protesters blocked the Crimean parliament and demanded a referendum on Crimea's independence. The rally was organized by the Crimean Front. Another large property of former president Yanukovych was discovered close to Sevastopol four times the size of that in the capital Kyiv. The Night Wolves were holding the administrative buildings of city of Simferopol and Kerch.

Also Russian armored personnel carriers were deployed to protect "Russian Interests" in the city of Sevastopol. The APCs with Russian marines were in Nakhimov Square and the courtyard of the Moscow House.

February 26

On February 26, thousands of protesters clashed in Simferopol. Near the Supreme Council of Crimea building between 4,000 and 5,000 Crimean Tatars and supporters of the Euromaidan-Crimea movement faced 600–700 supporters of pro-Russian organisations and the Russian Unity Party. Chairman of the Supreme Council of Crimea Volodymyr Konstantinov said that the Crimean parliament will not discuss the issue of separation from Ukraine and that earlier reports that parliament would discuss the motion were provocations. During the clashes, one man died of a heart attack and a woman died from being trampled. Crimean Tatars created self-defense groups and called on activists to unite with Russian, Ukrainian and people of other nationalities to avoid provocations and to protect churches, mosques, synagogues and other important sites. By nightfall, the Crimean Tatars had left, while the pro-Russian rally had grown to 5,000 as protesters arrived from Sevastopol later in the day. The new Ukrainian establishment's acting Interior Minister Arsen Avakov tasked Crimean law enforcement agencies not to provoke conflicts and to do whatever necessary to prevent clashes with pro-Russian forces and added that "I think, that way – through a dialogue – we shall achieve much more than with standoffs " The new head of the Security Service of Ukraine (SBU) Valentyn Nalyvaichenko requested United Nations round-the-clock monitoring of the security situation on the peninsula.

Also on February 26, media claimed that Russian troops or (as they themselves claimed) local volunteers took control of the main route of access to Sevastopol. A military checkpoint, with military vehicles under a Russian flag, was set up on the main highway between the city and Simferopol. CNN described them as a "pro-Russian militia checkpoint".

February 27

On February 27, at 4:20 local time, sixty pro-Russian gunmen seized Crimea's parliament building and Council of Ministers building. They were said to be professionals and heavily armed.

While the gunmen occupied Crimea's parliament building, the parliament held an emergency session. It voted to terminate the Crimean government, and replace Prime Minister Anatolii Mohyliov with Sergey Aksyonov. Aksyonov belonged to the Russian Unity party, which received 4% of the vote in the last election. It also voted to hold a referendum on greater autonomy on 25 May. The gunmen had cut all of the building's communications and took MPs' phones as they entered. No independent journalists were allowed inside the building while the votes were taking place. Some MPs claimed they were being threatened and that votes were cast for them and other MPs, even though they were not in the chamber.

Interfax-Ukraine reported "it is impossible to find out whether all the 64 members of the 100-member legislature who were registered as present at when the two decisions were voted on or whether someone else used the plastic voting cards of some of them" because due to the armed occupation of parliament it was unclear how many MPs were present. The head of parliament's information and analysis department, Olha Sulnikova, had phoned from inside the parliamentary building to journalists and had told them 61 of the registered 64 deputies had voted for the referendum resolution and 55 for the resolution to dismiss the government. They also installed a new Prime Minister. According to the Constitution of Ukraine, the Prime Minister of Crimea is appointed by the Supreme Council of Crimea in consultation with the President of Ukraine.

The chairman of the Supreme Council of Crimea, Volodymyr Konstantinov, as well as de facto prime minister Aksyonov, refused to recognize the dismissal of Viktor Yanukovych from presidential office, and view him as legitimate. Aksyonov added "we will follow his directions".

The new Prime Minister of Ukraine, Arseniy Yatsenyuk, warned "We must immediately declare that anyone who is on the streets with guns – these people are prosecuted by law".

Later in the day, Sevastopol International Airport was occupied in a similar manner as Simferopol's airport. According to the Minister of Internal Affairs, Arsen Avakov, soldiers without identification are Russian Black Sea Fleet troops. Later some television channels reported that airports are guarded by Russian forces.

The 13th Outpost, located in Feodosiya, became famous for its marginal resistance to the Russian forces and repetitive denial to give up. The speaker of Crimean Tatar people warned the Russian government that should their national integrity be compromised (as is the case with Ukraine), they will form an insurgency movement and will "defend" the lands they live on. Russia did not respond to the warning in any way.

At Donuzlav Bay, the Ukrainian minesweeper Cherkasy made a second ill-fated attempt to pass over the scuttled ships at the bay's entrance. At night, the Russian navy scuttled a fifth ship at the mouth of the bay.

Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States voted to suspend Russia from the Group of 8. Gregor Gysi, chairman of the German "Left" Party, has expressed his discontent with this decision (which was primarily brought by Angela Merkel) and responded by giving the February coup in Ukraine as example of what would be "not less unconstitutional" than the Crimean referendum. "The fascists who came to power in Ukraine, have their own understanding of what is constitutional, and the small percent of democrats sitting in the Rada cannot seem to influence it", he said.

A tug carrying Russian forces boarded and seized the amphibious ship Konstantin Olshansky at Donuzlav Bay. Ukrainian sources claim that 200 troops assaulted the vessel with the use of automatic weapons and stun grenades. The Ukrainian ship was manned by 20 crewmembers at the time, who laid up a smokescreen. Ukrainian sources report that the crew disabled the electronics and the engines of the vessel beyond repair before surrender.

Russia awards a medal to former Ukrainians who assisted in the annexation of Crimea. Controversy erupts over the reverse of the medallion, which dates "the return of Crimea" as February 20 — March 18. This implies that Russia was awarding those involved with the February 20 killing of Maidan protesters. After a two-hour engagement, the Ukrainian minesweeper Cherkasy, the last warship waving the Ukrainian ensign in Crimea was disabled with explosive charges and captured at Donuzlav Bay by the ocean-going tug Kovel, three speedboats, and two Mi-35 helicopters. There were no casualties, but the vessel's rudder was crippled by the explosion of a grenade. A bloodless exchange of small arms fire was reported; the Ukrainian crew was allowed to hoist the Ukrainian flag and stay aboard until their evacuation on 26 March.

The Russian President's Human Rights Council "posted a blog that was quickly taken down as if it were toxic radioactive waste" estimating that a "vast majority of the citizens of Sevastopol voted in favor of unification with Russia in the referendum (50-80%); in Crimea, various data show that 50-60% voted for unification with Russia, with a turnout of 30-50%," suggesting that the official results are false.
