Renaming of Crimean toponyms
Massive renaming of Crimean toponyms by the Soviet government took place during the conversion of the Crimean ASSR into the Crimean Oblast, in four waves (in 1944, 1945, 1948, and 1949). Renaming occurred after the deportation in 1944 of Crimean Tatars and other non-Slavic peoples living in Crimea.
