Tracing the historical development of the Crimean Tatar diaspora of Turkey, the Balkans and Central Asia, this paper looks first at the migration of this small Muslim ethnie from 1783 to the twentieth century, particularly after the Russian Empire’s victory in the Crimean War and Josef Stalin’s deportation of Muslim communities in the final year of World War II. Conquered, persecuted and scattered, the Crimean Tatars were either assimilated into host societies, as in Turkey, or rejected by them, as in Bulgaria and Romania. Yet, many maintained or rediscovered their Crimean Tatar identity in the twentieth century, especially during their long period of exile in Central Asia when they came to form a true diasporan community. Supported by their co-ethnics in Turkey and the Balkans, many Tatars took the opening that appeared in the final days of the Soviet Union to return to an uncertain future in their homeland. The case of the this little-studied ethnic group has obvious implications for scholars interested in ethnically-based oppression, national and diasporic identity construction and Muslim-Christian relations in the marginal zone between Christianity and Islam.
