Crimean Tatars, or simply Crimeans, are an Eastern European Turkic ethnic group and nation indigenous to Crimea. Their ethnogenesis lasted thousands of years in Crimea and the northern regions along the coast of the Black Sea, uniting Mediterranean populations with those of the Eurasian Steppe. Genome-wide study of the Crimean Tatars unveiled connections between them and the genomes of individuals from the Steppe during the Bronze Age, specifically those associated with the Yamnaya archaeological culture.
