How Russia Seized Crimea in 2014
Before Russia organized a referendum in Crimea, it controlled the parliament, airports, roads, communications, and approaches to Ukrainian military bases. The peninsula was not taken by a vote; military control came first, while Moscow denied that its soldiers were carrying out the operation.
A Vulnerable Moment in Kyiv
Viktor Yanukovych left Kyiv on February 21, 2014, after the deadliest days of the Revolution of Dignity. Parliament formed an interim administration and scheduled an election, but Ukraine's chain of command was shaken, its security institutions were divided, and the new government was still finding out whom it could trust.
Russia described the change of government as an extremist coup that threatened Russian speakers. In Crimea, competing pro-Ukrainian and pro-Russian crowds demonstrated outside the regional parliament, while Crimean Tatar leaders firmly opposed separation from Ukraine.
The instability gave Moscow a narrow opportunity. Russia already had thousands of authorized Black Sea Fleet personnel in Crimea, along with bases, transport, intelligence, and detailed knowledge of the peninsula.
The “Little Green Men” Appear
Before dawn on February 27, disciplined armed men in green uniforms without identifying insignia seized Crimea's parliament and Council of Ministers in Simferopol. They raised Russian flags, blocked entrances, and kept journalists and much of the public outside.
Armed personnel soon took control of airports, broadcasting facilities, roads, and other strategic sites. Their uniforms lacked badges, but their equipment, coordination, and conduct distinguished them from an improvised local militia.
The European Court of Human Rights later established that Russia exercised effective control over Crimea from February 27. It found that Russian servicemen supported the Crimean “self-defence” groups and that the operation could not be explained by the troops Russia was permitted to keep at its leased bases.
A Government Changed Under Armed Control
With the parliament building occupied, Crimean lawmakers dismissed the existing regional government and appointed Sergey Aksyonov as prime minister. Aksyonov led the small Russian Unity party and was acceptable to Moscow, but he had no broad electoral mandate to take control of the peninsula.
The closed parliamentary session was held while armed men controlled the building, and accounts disputed whether a valid quorum was present. The new authorities announced a referendum on Crimea's status, then moved its date forward and changed the question as Russian control expanded.
Ukraine's acting president rejected Aksyonov's appointment and the referendum decisions as unconstitutional. Those orders could not be enforced on a peninsula where armed units now controlled the main institutions.
Ukrainian Bases Are Surrounded
Russian forces and allied local units blockaded Ukrainian army, navy, air force, and border-guard facilities. Entrances were sealed with troops, vehicles, or crowds; commanders were pressed to surrender, defect, or accept confinement inside their own bases.
Ukraine's interim leaders feared that ordering resistance could trigger a much larger Russian invasion while the military was unprepared. Many Ukrainian personnel held their positions without opening fire, but they could not move freely, receive reinforcements, or restore government control.
Russia also prevented new Ukrainian forces from entering Crimea and secured the ferry crossing at Kerch. By early March, Kyiv retained isolated compounds rather than effective authority over the peninsula.
Denial, Then Admission
President Vladimir Putin initially said the armed men were local self-defence volunteers who had acquired uniforms in shops. Russian officials insisted that their forces were staying within the terms of the Black Sea Fleet agreements.
Putin later acknowledged that Russian servicemen had stood behind the Crimean forces, and Russia created a medal recognizing operations that began on February 20. The admission confirmed what the organization and equipment of the troops had already made clear.
By the time ballots were cast, armed resistance had been neutralized, Ukrainian television was being displaced, and the regional government had been replaced. The next step was the March 16 referendum and Russia's formal annexation—a vote conducted after the essential question of physical control had already been decided by force.
