Russian annexation of Crimea in the context of "Capture of the Crimean Parliament"

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 Russian annexation of Crimea took place in the aftermath of the 2014 Ukrainian Revolution of Dignity. 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.

Plausible deniability is a social tactic that allows people to deny knowledge, participation, or an active role in carrying out an activity, relaying a loaded message, etc. The deniability exists due to a lack of culpable evidence, or more commonly, from multiple plausible intrepretations of the present evidence. Plausible deniablity is prime shield of defense against accountability, and forms the basis of covert attacks that make up human social behavior.

In a chain of command, senior officials can deny knowledge or responsibility for actions committed by or on behalf of members of their organizational hierarchy. They may do so because of a lack of evidence that can confirm their participation, even if they were personally involved in or at least willfully ignorant of the actions. If illegal or otherwise disreputable and unpopular activities become public, high-ranking officials may deny any awareness of such acts to insulate themselves and shift the blame onto the agents who carried out the acts, as they are confident that their doubters will be unable to prove otherwise. The lack of evidence to the contrary ostensibly makes the denial plausible (credible), but sometimes, it makes any accusations only unactionable.

The Mejlis of the Crimean Tatar People (Crimean Tatar: Qırımtatar Milliy Meclisi) is the single highest executive-representative body of the Crimean Tatars in the period between sessions of the Qurultay of the Crimean Tatar People. The Mejlis is a member institution of the Platform of European Memory and Conscience.

The Mejlis was outlawed by Russia in 2016 for "the use of propaganda of aggression and hatred towards Russia, inciting ethnic nationalism and extremism in society" and listed as an extremist organization two years after the 2014 Russian annexation of Crimea. In April 2017, the International Court of Justice delivered its order on the request for the indication of provisional measures, according to which Russia must lift the ban; Russia has since ignored and refused to comply with the Court's decision.
