Toghuz-Uigur Empire.

Later, all these Western Uigurs, mentioned amongst the hordes that harassed the Eastern Empire in the fifth and sixth centuries, in association especially with the Turki Avars, disappear from history, being merged in the Ugrian and other Finnish peoples of the Volga basin. The Toghuz section also, after throwing off the yoke of the Mongol or Tungus Geugen (Jeu-Jen) in the fifth century, were for a time submerged in the vast empire of the Altai Turks, founded in 552 by Tumen of the House of Assena (A-shi-na), who was the first to assume the title of Kha-Khan, "Great Khan," and whose dynasty ruled over the united Turki and Mongol peoples from the Pacific to the Caspian, and from the Frozen Ocean to the confines of China and Tibet. Both the above-mentioned Sinjibu, who received the Byzantine envoy, and the Bilga Khan of the Orkhon stele, belonged to this dynasty, which was replaced in 774 by Pei-lo (Huei-hu), chief of the Toghuz-Uigurs. This is how we are to understand the statement that all the Turki peoples who during the somewhat unstable rule of the Assena dynasty from 552 to 774 had undergone many vicissitudes, and about 580 were even broken into two great sections (Eastern Turks of the Karakoram region and Western Turks of the Tarim basin), were again united in one vast political system under the Toghuz-Uigurs. These are henceforth known in history simply as Uigurs, the On branch having, as stated, long disappeared in the West. The centre of their power seems to have oscillated between Karakoram and Turfan in Eastern Turkestan, the extensive ruins of which have been explored by D. A. Klements, Sven Hedin and M. A. Stein. Their vast dominions were gradually dismembered, first by the Hakas, or Ki-li-Kissé, precursors of the present Kirghiz, who overran the eastern (Orkhon) districts about 840, and then by the Muhammadans of Máwar-en-Nahar (Transoxiana), who overthrew the "Lion Kings," as the Uigur Khans of Turfan were called, and set up several petty Mussulman states in Eastern Turkestan. Later they fell under the yoke of the Kara-Khitais, and were amongst the first to join the devastating hordes of Jenghiz-Khan; their name, which henceforth vanishes from history[696], has been popularly recognised under the form of "Ogres," in fable and nursery tales, but the derivation lacks historical foundation.

At present the heterogeneous populations of the Tarim basin (Kashgaria, Eastern Turkestan), where the various elements have been intermingled, offer a striking contrast to those of the Ili valley (Sungaria), where one invading horde has succeeded and been superimposed on another. Hence the complexity of the Kashgarian type, in which the original "horse-like face" everywhere crops out, absorbing the later Mongolo-Turki arrivals. But in Sungaria the Kalmuk, Chinese, Dungan, Taranchi, and Kirghiz groups are all still sharply distinguished and perceptible at a glance. "Amongst the Kashgarians—a term as vague ethnically as 'Aryan'—Richthofen has determined the successive presence of the Su, Yué-chi, and Usun hordes, as described in the early Chinese chronicles[697]."

The recent explorations of M. A. Stein have thrown some light on the ethnology of this region, and a preliminary survey of results was prepared and published by T. A. Joyce. He concludes that the original inhabitants were of Alpine type, with, in the west, traces of the Indo-Afghan, and that the Mongolian has had very little influence upon the population[698].

The Oghuz Turks and their Migrations.

In close proximity to the Toghuz-Uigurs dwelt the Oghuz (Ghuz, Uz), for whom eponymous heroes have been provided in the legendary records of the Eastern Turks, although all these terms would appear to be merely shortened forms of Toghuz[699]. But whether true Uigurs, or a distinct branch of the Turki people, the Ghuz, as they are commonly called by the Arab writers, began their westward migrations about the year 780. After occupying Transoxiana, where they are now represented by the Uzbegs[700] of Bokhara and surrounding lands, they gradually spread as conquerors over all the northern parts of Irania, Asia Minor, Syria, the Russian and Caucasian steppes, Ukrainia, Dacia, and the Balkan Peninsula. In most of these lands they formed fresh ethnical combinations both with the Caucasic aborigines, and with many kindred Turki as well as Mongol peoples, some of whom were settled in these regions since neolithic times, while others had either accompanied Attila's expeditions, or followed in his wake (Pechenegs, Komans, Alans, Kipchaks, Kara-Kalpaks), or else arrived later in company with Jenghiz-Khan and his successors (Kazan and Nogai "Tatars"[701]).

In Russia, Rumania (Dacia), and most of the Balkan Peninsula these Mongolo-Turki blends have been again submerged by the dominant Slav and Rumanian peoples (Great and Little Russians, Servo-Croatians, Montenegrini, Moldavians, and Walachians). But in south-western Asia they still constitute perhaps the majority of the population between the Indus and Constantinople, in many places forming numerous compact communities, in which the Mongolo-Turki physical and mental characters are conspicuous. Such, besides the already mentioned Turkomans of Parthian lineage, are all the nomad and many of the settled inhabitants of Khiva, Ferghana, Karategin, Bokhara, generally comprised under the name of Uzbegs and "Sartes." Such also are the Turki peoples of Afghan Turkestan, and of the neighbouring uplands (Hazaras and Aimaks who claim Mongol descent, though now of Persian speech); the Aderbaijani and many other more scattered groups in Persia; the Nogai and Kumuk tribes of Caucasia, and especially most of the nomad and settled agricultural populations of Asia Minor. The Anatolian peasantry form, in fact, the most numerous and compact division of the Turki family still surviving in any part of their vast domain between the Bosporus and the Lena.

Seljuks and Osmanli.

Out of this prolific Oghuz stock arose many renowned chiefs, founders of vast but somewhat unstable empires, such as those of the Gasnevides, who ruled from Persia to the Indus; the Seljuks, who first wrested the Asiatic provinces from Byzantium; the Osmanli, so named from Othman, the Arabised form of Athman, who prepared the way for Orkhan (1326-60), true builder of the Ottoman power, which has alone survived the shipwreck of all the historical Turki states. The vicissitudes of these monarchies, looked on perhaps with too kindly an eye by Gibbon, belong to the domain of history, and it will suffice here to state that from the ethnical standpoint the chief interest centres in that of the Seljukides, covering the period from about the middle of the eleventh to the middle of the thirteenth century. It was under Togrul-beg of this dynasty (1038-63) that "the whole body of the Turkish nation embraced with fervour and sincerity the religion of Mahomet[702]." A little later began the permanent Turki occupation of Asia Minor, where, after the conquest of Armenia (1065-68) and the overthrow of the Byzantine emperor Romanus Diogenes (1071), numerous military settlements, followed by nomad Turkoman encampments, were established by the great Seljuk rulers, Alp Arslan and Malek Shah (1063-92), at all the strategical points. These first arrivals were joined later by others fleeing before the Mongol hosts led by Jenghiz-Khan's successors down to the time of Timur-beg. But the Christians (Greeks and earlier aborigines) were not exterminated, and we read that, while great numbers apostatised, "many thousand children were marked by the knife of circumcision; and many thousand captives were devoted to the service or the pleasures of their masters" (ib.). In other words, the already mixed Turki intruders were yet more modified by further interminglings with the earlier inhabitants of Asia Minor. Those who, following the fortunes of the Othman dynasty, crossed the Bosporus and settled in Rumelia and some other parts of the Balkan Peninsula, now prefer to call themselves Osmanli, even repudiating the national name "Turk" still retained with pride by the ruder peasant classes of Asia Minor. The latter are often spoken of as "Seljuk Turks," as if there were some racial difference between them and the European Osmanli, and for the distinction there is some foundation. As pointed out by Arminius Vambéry[703], the Osmanli have been influenced and modified by their closer association with the Christian populations of the Balkan lands, while in Anatolia the Seljuks have been able better to preserve the national type and temperament. The true Turki spirit ("das Türkentum") survives especially in the provinces of Lykaonia and Kappadokia, where the few surviving natives were not only Islamised but ethnically fused, whereas in Europe most of them (Bosnians, Albanians) were only Islamised, and here the Turki element has always been slight.
