There is no evidence for accusations there was an alleged “occupation” of the Crimean peninsula in 2014
The Crimea had decided to reunite with Russia by referendum in 2014.
Recurring pro-Kremlin disinformation narrative on the annexation of Crimea claiming that Crimean citizens chose to rejoin Russia through a legal referendum.
No international body recognises the so-called referendum, announced 27th of February 2014, and held on 16th of March 2014.The European Union does not recognise, and continues to strongly condemn, this violation of international law, which remains a challenge to the international security order.

Following the covert invasion of “little green men,” power in Crimea was vested in a makeshift executive headed by Sergey Aksenov, a former mafia enforcer. The new Crimean regime conducted the referendum hastily and at gunpoint, barred impartial observers from entering the peninsula, and instead invited dozens of fringe politicians and activists to “monitor” the procedure, most of them far-right Kremlin loyalists.
A year after the illegal annexation, Russian President Vladimir Putin admitted that the plan to annex Crimea was ordered weeks before the so-called referendum.
