end of the 15th century, the main prerequisites that led to the formation of an independent Crimean Tatar ethnic group were created: the political dominance of the Crimean Khanate was established in Crimea, the Turkic languages (Cuman-Kipchak on the territory of the khanate) became dominant, and Islam acquired the status of a state religion throughout the Peninsula.
