In 1945 it was converted into the Crimean Oblast of RSFSR, which was transferred to Ukrainian SSR in 1954.
Following a referendum held on January 20, 1991 the Crimean Autonomous Soviet Socialist Republic was reestablished on February 12, 1991 by the Supreme Soviet of the Ukrainain SSR. Today it is officially named the Autonomous Republic of Crimea.
