Much more important are the languages belonging to the third branch of the Turanian family, most prominent among which is the Turkish or Osmanli of [pg 301] Constantinople. The number of the Turkish inhabitants of European Turkey is indeed small. It is generally stated at 2,000,000; but Shafarik estimates the number of genuine Turks at not more than 700,000, who rule over fifteen millions of people. The different Turkic dialects of which the Osmanli is one, occupy one of the largest linguistic areas, extending from the Lena and the Polar Sea, down to the Adriatic.

The most ancient name by which the Turkic tribes of Central Asia were known to the Chinese was Hiung-nu. These Hiung-nu founded an empire (206 b. c.) comprising a large portion of Asia, west of China. Engaged in frequent wars with the Chinese, they were defeated at last in the middle of the first century after Christ. Thereupon they divided into a northern and southern empire; and, after the southern Hiung-nu had become subjects of China, they attacked the northern Hiung-nu, together with the Chinese, and, driving them out of their seats between the rivers Amur and Selenga, and the Altai mountains, westward, they are supposed to have given the first impulse to the inroads of the barbarians into Europe. In the beginning of the third century, the Mongolic and Tungusic tribes, who had filled the seats of the northern Hiung-nu, had grown so powerful as to attack the southern Hiung-nu and drive them from their territories. This occasioned a second migration of Asiatic tribes towards the west.

Another name by which the Chinese designate these Hiung-nu or Turkish tribes is Tu-kiu. This Tu-kiu is supposed to be identical with Turk, and, although the tribe to which this name was given was originally but small, it began to spread in the sixth century from [pg 302] the Altai to the Caspian, and it was probably to them that in 569 the Emperor Justinian sent an ambassador in the person of Semarchos. The empire of the Tu-kiu was destroyed in the eighth century, by the 'Hui-'he (Chinese Kao-che). This tribe, equally of Turkish origin, maintained itself for about a century, and was then conquered by the Chinese and driven back from the northern borders of China. Part of the 'Hui-'he occupied Tangut, and, after a second defeat by the Mongolians in 1257, the remnant proceeded still further west, and joined the Uigurs, whose tents were pitched near the towns of Turfan, 'Kashgar, 'Hamil, and Aksu.

These facts, gleaned chiefly from Chinese historians, show from the very earliest times the westward tendency of the Turkish nations. In 568 Turkish tribes occupied the country between the Volga and the sea of Azov, and numerous reinforcements have since strengthened their position in those parts.

The northern part of Persia, west of the Caspian Sea, Armenia, the south of Georgia, Shirwan, and Dagestan, harbor a Turkic population, known by the general name of Turkman or Kisil-bash (Red-caps). They are nomadic robbers, and their arrival in these countries dates from the eleventh and twelfth centuries.

East of the Caspian Sea the Turkman tribes are under command of the Usbek-Khans of Khiva, Fergana, and Bukhára. They call themselves, however, not subjects but guests of these Khans. Still more to the east the Turkmans are under Chinese sovereignty, and in the south-west they reach as far as Khorasan and other provinces of Persia.

The Usbeks, descendants of the 'Huy-'he and Uigurs, [pg 303] and originally settled in the neighborhood of the towns of 'Hoten, Kashgar, Turfan, and 'Hamil, crossed the Yaxartes in the sixteenth century, and after several successful campaigns gained possession of Balkh, Kharism (Khiva), Bukhára, and Ferganah. In the latter country and in Balkh they have become agricultural; but generally their life is nomadic, and too warlike to be called pastoral.

Another Turkish tribe are the Nogái, west of the Caspian, and also north of the Black Sea. To the beginning of the seventeenth century they lived north-east of the Caspian, and the steppes on the left of the Irtish bore their name. Pressed by the Kalmüks, a Mongolic tribe, the Nogáis advanced westward as far as Astrachan. Peter I. transferred them thence to the north of the Caucasian mountains, where they still graze their flocks on the shores of the Kuban and the Kuma. One horde, that of Kundur, remained on the Volga, subject to the Kalmüks.

Another tribe of Turkish origin in the Caucasus are the Bazianes. They now live near the sources of the Kuban, but before the fifteenth century within the town Majari, on the Kuma.

A third Turkish tribe in the Caucasus are the Kumüks on the rivers Sunja, Aksai, and Koisu: now subjects of Russia, though under native princes.
