the Karaim language belongs to the Kipchak linguistic group, and the Khazar language belongs to the Bulgar group; there is no close relationship between these two Turkic languages;[9] According to the Khazar Correspondence, Khazar Judaism was, most likely, Talmudic.[10] The tradition of Karaite Judaism ranks only the Tanakh as a holy book and does not recognize the Talmud; and Khazars disappeared in the 11th century. But, the first written mention of the Crimean Karaites was in the 14th century.[11]
