Close to this group, but farther to the East, the central group also concerns us, for some of its representatives who now inhabit the boundaries of Europe made repeated incursions into Europe in various directions. In the plains lying between the River Irtish and the Caspian Sea live the Kirghiz-Kazaks, and in the Tien-Shien Mountains the Kara-Kirghiz, who have preserved many ancient Old Turkish customs, and seem to have been only slightly Mohammedanised. The Usbegs and the Sartis of Russian Turkistan, on the other hand, have been more or less Iranised. Finally, on the banks of the Volga are to be found the Tatars of European Russia. Among them the Tatars of Kazan, who are descended from the Kiptchaks, came to the banks of the Volga in the thirteenth century and mingled with the Bulgars. These Tatars differ from the Tatars of Astrakhan, who are descendants of the Turco-Mongols of the Golden Horde, and are connected with the Khazars, and from the Nogaïs of the Crimea, who are Tatars of the steppes who more or less inter-married with other races—the Tatars of the Tauris coast being the hybrid descendants of the Adriatic race and the Indo-Afghan race. They are to be found near Astrakhan and in the Caucasus Mountains, and even, perhaps, as far as Lithuania, “where, though still being Mohammedans, they have adopted the language and costume of the Poles.”[1]
The invasion of Europe by the Turks appears as the last great ethnic movement that followed the so-called period of migration of peoples (second to sixth centuries A.D.) and the successive movements it entailed.
Let us consider only the migrations of those who concern us most closely, and with whom the Turks were to come into contact later on. First the Slavs spread westward towards the Baltic and beyond the Elbe, and southward to the valley of the Danube and the Balkan Peninsula. This movement brought about the advance of the Germans towards the west, and consequently the advance of the Celts towards Iberia and as far as Spain. Owing to the invasion of the Huns in the fifth century and in the sixth of the Avars, who, after coming as far as Champagne, settled down in the plains of Hungary and the territories lying farther to the south which had already been occupied by the Dacians for several centuries, the Slavs were cut into two groups. About the same time, the Bulgars came from the banks of the Volga and settled on the banks of the Danube.
In the ninth century, owing to a new migration of masses of Slavonic descent, the Hungarians, driven by tribes of Petchenegs and Polovts into Southern Russia, crossed the Carpathian Mountains and took up their abode in the valley of the Tirzah. While the Magyar Turks settled in Hungary, the Kajar Turks occupied the hinterland of Thessalonica in Macedonia. In the twelfth century, the Germans, driving the Western Slavs as far as the banks of the Vistula, brought about a reaction towards the north-east of the Eastern Slavs, whose expansion took place at the expense of the Finnish tribes that lived there.
Only in the thirteenth century did the Turco-Mongols begin to migrate in their turn; they occupied the whole of Russia, as far as Novgorod to the north, and reached Liegnitz in Silesia. But, although they soon drew back from Western Europe, they remained till the fifteenth century in Eastern Russia, and in the eighteenth century they were still in the steppes of Southern Russia, and in the Crimea.
Finally, in the fourteenth and fifteenth centuries, the Osmanli Turks invaded the Balkan Peninsula, where they met such of their kindred as the Kajars, the Tchitaks, and the Pomaks, who were heathens or Christians, and later on embraced Islam. They invaded Hungary and made incursions into Lower Austria.
Then began the migration of the Little Russians into the upper valley of the Dnieper, and in the sixteenth century they set off towards the steppes of Southern Russia, while the Great Russians began to advance beyond the Volga towards the Ural, a movement which reached Siberia, and still continues.
It follows, necessarily, that in the course of these huge migrations, the so-called Turkish race was greatly modified; the Turks of the Eastern group mixed with the Mongols, the Tunguses, and the Ugrians; and those of the Western group in Asia and Europe with various Indo-Afghan, Assyrian, Arab, and European elements, especially with those living near the Adriatic: the Greeks, the Genoese, the Goths, etc. Thus the Osmanli Turks became a mixture of many races.
Though ethnologists do not agree about the various ethnic elements of the Turco-Tatar group, it is certain, all the same, that those who came to Asia Minor early associated for a long time with the people of Central Asia, and Vambéry considers that a Turkish element penetrated into Europe at a very early date.[2]
