2014 Russian annexation of Crimea

On February 16, 2015, the Ukrainian parliament officially enacted legislation defining February 20, 2014—when Russia’s military operation began—as the start date of Crimea’s temporary occupation. This legal designation underscored Ukraine’s rejection of annexation and its commitment to reclaim sovereignty.

On September 14, 2014, Crimea held its first parliamentary elections since annexation, organized under Russian authority. United Russia secured a landslide victory, capturing approximately 73% of the vote and 70 out of 75 seats in the State Council of Crimea. This solidified political integration into the Russian system.

On May 9, 2014, President Vladimir Putin delivered a speech in Sevastopol during Victory Day celebrations, celebrating what Russia termed the reunification of Crimea. The event bolstered Russian domestic approval and showcased Crimea’s symbolic role in Russia’s national narrative.

On March 27, 2014, the United Nations General Assembly adopted a resolution affirming Ukraine’s territorial integrity and declaring the Crimean referendum and subsequent annexation invalid under international law. The resolution characterized Crimea as an occupied territory and garnered majority support among UN member states.

By March 21, 2014, both houses of Russia’s Federal Assembly had ratified the accession treaty, making the annexation legally binding under Russian law. The State Duma and Federation Council approved the treaty, despite widespread international condemnation labeling the action illegal under international law.

On March 18, 2014, a treaty was signed between representatives of Crimea and the Russian Federation formalizing the immediate admission of Crimea and Sevastopol as Russian federal subjects. This treaty was swiftly followed by court approval and parliamentary ratification, marking the formal annexation of the peninsula by Russia.

On March 16, 2014, Crimea held a status referendum under Russian occupation, offering a choice between joining Russia or restoring the 1992 Crimean constitution as part of Ukraine. Organized and conducted under military occupation, the vote—officially reporting over 95% in favor of joining Russia—was widely rejected internationally as illegitimate and coercive.

At a press conference on March 4, 2014, President Vladimir Putin stated that Russia had no intention to annex Crimea or invade Ukraine, although Russian forces had effectively established full control over the peninsula by that time. This public denial came while occupation was already a fait accompli.

On March 1, 2014, Russia’s Federation Council (upper house of parliament) approved President Putin’s request to deploy Russian military forces to Ukraine to “stabilize” the situation. Concurrently, Crimea’s new government requested Russian assistance to maintain order. This legislative approval provided the legal pretext for overt military involvement.

On February 27, 2014, armed personnel in unmarked uniforms seized control of the Crimean parliament building in Simferopol and other government buildings across the peninsula. They raised Russian flags and established checkpoints, prompting the local parliament to dismiss the existing government and install Sergey Aksyonov as prime minister. These actions constituted the rapid escalation of the takeover.

Around February 20, 2014, amid escalating unrest in Kyiv and the ousting of President Yanukovych, covert Russian forces—commonly dubbed “little green men”—began appearing in Crimea. These unmarked soldiers, along with local Cossack-aligned self-defense formations, initiated the destabilization of the region and paved the way for subsequent seizure of key facilities and rapid territorial takeover. This marked the covert start of the annexation operation.
