What, then, are we to suppose is the origin of all those tribes who, under the name of Tatars, now inhabit the south of Russia? We agree entirely with the opinion put forth in Courtin's "Encyclopedie Moderne," that these Tatars are nothing but Turks, Comans, or Petshenegues, who having been at the commencement of the thirteenth century masters of all the countries north and west of the Caspian Sea as far the Dniepr, were afterwards subdued by the sons of Genghis Khan, and contributed towards the foundation of a new empire comprised between the Dniepr and the Emba, to which was given the name of Kaptshak, or Kiptshak, a designation which appears to have been originally that of the territory.
The princes of this empire were Mongols or Tatars, but the majority of their subjects were Turks. It appears even that the latter formed a large portion of the armies of Genghis Khan in his late expeditions. The Turkish language thus remained predominant throughout the Kaptshak, Little and Great Bokhara, and among the Bashkirs and Tchouvaches. A few Mongol words are still found in the Turkish dialect of the Russian Mahometans, but they are extremely rare, and this may be easily explained. The soldiers of the Mongol army were of course bachelors, and when they married Kaptshak women, their children adopted the language of their mothers. The sovereigns themselves of this new empire soon embraced Mahometanism. Bereke, the brother and successor of Batou, set the first example; Usbeck Khan, who reigned in 1305, followed in his steps, and declared himself the protector of Islam, which thenceforth became the creed of the conquerors as well as of the conquered.
It must not be inferred from the preceding statement that the Turks and Mongols may not, in more remote times, have belonged to one and the same race; we are not quite of that opinion; we have considered the Turkish race only under the conditions in which it appeared in Europe and Asia about the twelfth century, that is to say, modified by long contact with the Caucasian nations, and we have left altogether out of view what it may previously have been. Moreover, if De Guignes is rightly informed, the inhabitants of the Kaptshak are really of Mongol origin, and the soldiers of Genghis Khan took pains to prove to them that they were their countrymen.
Towards the close of the fifteenth century, the empire of the Kaptshak was divided into several khanats--Kasan, Astrakhan, and the Crimea, the rulers of which, descended from Genghis, were all Mongols; but then they had no longer armies drawn from the interior of Asia, and the Turkish element finally prevailed throughout the whole population. Still, it cannot be denied that the Mahometan hordes of Russia present some resemblance to the Mongols, and this tends to confirm the ideas we have expressed above. But then it is obvious that two nations that served so long under the same banners, and lived under the same government, must have intermarried with each other, and that their blood must have been frequently mingled. Moreover, it is a most remarkable fact, with what pertinacity the Mongol type maintains its identity in spite of the mixture of many generations; a few marriages are sufficient to spread traces of it in the course of a certain time, over a whole nation. I have seen one example of this in the Cossacks, who have been living amidst the Kalmucks for about two hundred years.
The Tatars in the mountains of the Crimea more rarely exhibit Mongol features; the Greek profile is frequently found among them. This difference is owing to their mixture with the Goths, the Greeks, and the remnants of other nations that have successively overrun the peninsula.
The Nogais, who inhabit the plains of the Crimea, and the steppes of the Sea of Azof, are unquestionably the nearest in appearance to the Mongols of all the Tatars, and generally their physiognomy is such as cannot be attributed to any other origin. Moreover, according to their own traditions, they never made part of the Kaptshak, nor did they arrive in Europe until subsequently to the death of Genghis Khan, after having dwelt from time immemorial, if not with the Mongols, at least in their vicinity.
