Crimea has always belonged to Russia, Krushchev gave it to Ukraine on a whim.
Recurrent pro-Kremlin disinformation narrative on Crimea being a part of Russia.
According to the international law Crimea is a part of Ukraine. Russia violated the international law as well as key principles of the European security framework by illegally annexing the Autonomous Republic of Crimea and the City of Sevastopol. 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. This position is based on the UN Charter, which clearly states that the territory of a State cannot be acquired by another State resulting from the threat or use of force, as well as on the Helsinki Final Act in which the signatories declared their intention to respect the inviolability of frontiers and territorial integrity.
UNGA Resolution 68/262, stating that the Crimean referendum was not valid and condemning Russia's illegal actions in Ukraine, was supported by 100 United Nations member states.
The Office of the Prosecutor of the International Criminal Court stated that “[t]he information available suggests that the situation within the territory of Crimea and Sevastopol amounts to an international armed conflict between Ukraine and the Russian Federation. This international armed conflict began at the latest on 26 February when the Russian Federation deployed members of its armed forces to gain control over parts of the Ukrainian territory without the consent of the Ukrainian Government."

On January 23, 2019, the Ukrainian Embassy in France published the following open letter for the French audience on the history of Crimea: "saying that Crimea is Russian "for centuries" is, to say the least, excessive. Crimea was annexed in 1783, already in violation of a treaty which guaranteed the independence of the Tatar khanate. The peninsula was in the middle of the nineteenth century a territory in the process of colonization. In 1897, the first comprehensive census of the population of the empire indicates that the Russians are only one third of the inhabitants of Crimea, where they are still slightly fewer than the Tatars. The Russians only became a majority after the complete deportation in 1944 of the Tatars, who could only return after the fall of the communist regime. The annexation of Crimea to the then Soviet Ukraine, in 1954, was not done on a not ethnic, but geographical and economic basis, and as an extension of very old historical links between the peninsula and adjoining mainland areas. But what is more important today than the circumstances of 1954 and even more so of 1854 is that the borders of Ukraine, including Crimea, were recognized and guaranteed after its independence in 1991 by international agreements, some of which were signed by Russia itself".
