The transfer of the Crimean oblast to Ukraine has been described as a "symbolic gesture", marking the
300th anniversary of the 1654
Treaty of Pereyaslav, called the "Reunification of Ukraine with Russia" in the Soviet Union. It was also attributed to
Communist Party first secretary Nikita Khrushchev, although the person who signed the document was Chairman
Kliment Voroshilov, the Soviet Union's
de jure head of state. The transfer had taken place on the basis of "the integral character of the economy, the territorial proximity and the close economic and cultural ties between the Crimea Province and the Ukrainian SSR" and to commemorate the 300th anniversary of Ukraine's union with Russia (also known in the Soviet Union as the
Pereiaslav Agreement). Mark Kramer, professor of Cold War Studies at
Harvard University, also claimed that the transfer was partly to help Khruschev's then-precarious political position against the Prime Minister
Georgii Malenkov through winning support of the
First Secretary of the Communist Party of Ukraine Aleksey Kirichenko. Kramer believed that the transfer also aimed to greatly increase the number of ethnic Russians in the Ukrainian SSR which itself was going through problems integrating previous
Polish territory due to organized Ukrainian nationalist resistance.
Nina Khrushcheva, a political scientist and the great-granddaughter of
Nikita Khrushchev, said of his motivation, "it was somewhat symbolic, somewhat trying to reshuffle the centralized system and also, full disclosure, Nikita Khrushchev was very fond of Ukraine, so I think to some degree it was also a personal gesture toward his favorite republic. He was ethnically Russian, but he really felt great affinity with Ukraine." Since
Sevastopol in Crimea was the site of the
Black Sea Fleet, a quintessential element of Soviet and then of Russian foreign policy, the transfer had the intended effect of binding Ukraine inexorably to Russia, "Eternally Together", as a poster commemorating the event proclaimed. Other reasons given were the integration of the economies of Ukraine and Crimea and the idea that Crimea was a natural extension of the
Ukrainian steppes. There was also a desire to repopulate parts of Crimea with Slavic peoples, mainly Russians and Ukrainians, after the peninsula was subject to
large-scale deportations of
Crimean Tatars to Central Asia by the Soviet regime in 1944. Sergey Minchik, the grandson of
Dmitry Polyansky, who headed Crimea from 1952 to 1955, writes that Khrushchev decided to transform a Russia boarders in order to "pacify" a suffering Ukraine and to start his reform of restructuring the USSR along the lines of the United States, which has no national regions. ==Aftermath==
