The "Sürgün", the deportation of the Crimean Tatars by the Soviets during the Second World War, took place on 18 May 1944 in Bakhchysarai. The expulsion was prompted by accusations that the Tatars had collaborated with the Axis occupiers (1941-1944). Although deportation of some Tatars in Crimea had begun as early as 1860, during the era of the Russian Empire, the Sürgün delivered the final blow, as the city was rendered empty of Crimean Tatars. They were not to return to the city until 1989, when Soviet policies relaxed.
