The Crimean Oblast (Ukrainian: Кримська область Kryms’ka oblast’ ; Russian: Крымская область Krymskaya oblast’ ; Crimean Tatar: Qırım vilâyeti) was an oblast (province) of the former Russian SFSR (1945–1954) and Ukrainian SSR (1954–1991) within the Soviet Union. Its capital was the city of Simferopol.
The Crimean Oblast was created from the newly abolished Crimean ASSR on June 30, 1945. The oblast was then transferred from the Russian SFSR to the Ukrainian SSR on February 19, 1954.
Following a referendum held on January 20, 1991, the Crimean Oblast was upgraded to that of an Autonomous Soviet Socialist Republic on February 12, 1991, by the Supreme Soviet of the Ukrainian SSR. Today it is officially named the Autonomous Republic of Crimea.
