Until the 20th century, Crimean Tatars were the most populous demographic cohort in Crimea, constituting the majority of the peninsula's population as a whole.[16][17] Following the Russian Empire's annexation of the Crimean Khanate in 1783, they were subjected to attempts at driving them from the region through a combination of physical violence and harassment, forced resettlement, and legalized forms of discrimination. By 1800, between 100,000 and 300,000 Crimean Tatars had left Crimea.
While Crimean Tatar cultural elements were not completely eradicated under the Romanov dynasty, the populace was almost completely eradicated from the peninsula under the Soviet Union, especially during the Stalinist era.[18] In May 1944, almost immediately after the Soviets retook German-occupied Crimea during World War II, the country's State Defense Committee ordered the deportation of all Crimean Tatars, including the families of Crimean Tatar soldiers in the Red Army. The deportees were transported in trains and boxcars to Central Asia, where they were primarily resettled in Uzbekistan. Anywhere from 18% to 46% of the Crimean Tatar population was lost due to the Soviet deportation campaigns.[19] From 1967 onwards, only a few of the displaced Crimean Tatars were allowed to return, although de-Stalinization had led to the Soviet government's recognition of the deportations as ethnic cleansing and cultural genocide. Later, in 1989, the Supreme Soviet of the Soviet Union adopted new policies for the full right of return of the Crimean Tatars, sparking a steady increase in the population.
