There was no coup d’état in Kyiv in 2014; this is a longstanding pro-Kremlin disinformation narrative about Ukraine's Euromaidan protests.
The spontaneous onset of the Euromaidan protests was a reaction from several segments of the Ukrainian population to former President Yanukovych’s sudden departure from the promised Association Agreement with the European Union in November 2013, as a result of pressure from Russia.
The article also contains a recurring pro-Kremlin disinformation narrative on the annexation of Crimea claiming that Crimea has "returned" to Russia.
The transfer of Crimea and Sevastopol to Ukraine was first officially agreed on 25 January 1954 at a meeting of the Presidium of the CPSU Central Committee. The members of the Presidium, voting for the transfer of Crimea to Ukraine, took into account objective reasons: “the commonality of the economy, territorial proximity and close economic and cultural ties between the Crimean region and the Ukrainian SSR.”
On 19 February 1954, the Supreme Soviet of the USSR confirmed the need for Crimea to join Soviet Ukraine. Legally, the transfer of Crimea to Ukraine ended on 26 April 1954, on the basis of the relevant law of the Supreme Soviet of the USSR. According to international law, Crimea is a part of Ukraine.
After the collapse of the USSR, Russia reaffirmed respect for the territorial integrity and sovereignty of Ukraine.
By signing the 1997 Friendship Treaty, Russia also recognised that Crimea is an integral part of Ukraine.
The Office of the Prosecutor of the International Criminal Court has stated 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 2014 when the Russian Federation deployed members of its armed forces to gain control over parts of Ukrainian territory without the consent of the Ukrainian Government".
