After the revolution, the Bolsheviks, for a number of reasons – may God judge them – added large sections of the historical South of Russia to the Republic of Ukraine. This was done with no consideration for the ethnic make-up of the population, and today these areas form the southeast of Ukraine. Then, in 1954, a decision was made to transfer Crimean Region to Ukraine, along with Sevastopol, despite the fact that it was a city of union subordination. This was the personal initiative of the Communist Party head Nikita Khrushchev. What stood behind this decision of his – a desire to win the support of the Ukrainian political establishment or to atone for the mass repressions of the 1930’s in Ukraine – is for historians to figure out.
What matters now is that this decision was made in clear violation of the constitutional norms that were in place even then. The decision was made behind the scenes. Naturally, in a totalitarian state nobody bothered to ask the citizens of Crimea and Sevastopol. They were faced with the fact. People, of course, wondered why all of a sudden Crimea became part of Ukraine. But on the whole – and we must state this clearly, we all know it – this decision was treated as a formality of sorts because the territory was transferred within the boundaries of a single state. Back then, it was impossible to imagine that Ukraine and Russia may split up and become two separate states. However, this has happened.From: Transcript: Putin says Russia will protect the rights of Russians abroad (March 18, 2014)
