A peculiar interest surrounds these wandering tribes of the desert. In them we see the living representatives of the ancient Huns, and of the yet more ancient Scythians. Of them came Attila, "the Scourge of God," who with his barbarian hordes shook the foundations of Europe in the fifth century, and accelerated the downfall of the old Roman empire; of them came also the redoubtable warriors who desolated Asia and Europe six hundred years ago.

The Mongol tribes are exceedingly conservative in their habits; their fashions never change. A description of their manners in the time of Genghis, or even of Attila, is equally applicable now. Everything goes to show that in the form of their tents, in their dress, their social customs, and their mode of life, the Mongols of to-day have changed but little since they first became known to history.

The early history of the Huns is involved in obscurity. They appear to have existed as a pastoral people, inhabiting the east of the desert of Gobi from about 1200 B.C., during which time they were frequently at war with the Chinese. The first authentic accounts of them date from about the year 200 B.C., when they greatly extended their empire, and became very formidable neighbours to China. It was in the third century before the Christian era that the Chinese built the famous wall as a protection from the inroads of the warlike Huns, who, notwithstanding, laid China under tribute.

Vouti, of the Han dynasty (died 87 B.C.), gained a bloody victory over the Huns, and was the first to break their power in China. He followed up his military success by the application of the craft for which his race was, even at that early date, distinguished. By diligently promoting dissension among the tribes he succeeded in severing many of them from their allegiance to the Tanjou, the title then adopted by the kings of the Huns. The Tanjou himself became afterwards a vassal to the Chinese emperors, and was fain to lick the dust for a dependent kingship.

About 100 years after the birth of Christ, the Huns were broken up and scattered. The Huns of the South, who had previously seceded from the main body, and had established their dynasty in alliance with China, held together till the year 216 A.D. The Northern Huns, being distressed by a great famine, were attacked by the tribes whom they had so long oppressed, and were compelled to seek safety in flight. From that era we must date the migrations of the Hunnish tribes. They were again subdivided. One branch wandered to the coast of the Caspian Sea, where they settled, and became modified in their character under the influence of a more genial climate; their nomad habits were gradually abandoned; and they became civilised. These were called the White Huns.

Another branch migrated in a north-westerly direction, and in their march had to contend with a more rigorous climate. Exasperated by their struggles with the elements and with many enemies, they retained all their savageness in their new settlement on the Volga. These restless warriors had barely secured their own existence in the west, when they began to attack their neighbours. After conquering the Alani, a nation only a little less barbarous than themselves, and adding to their own forces those of the vanquished tribes, the Huns became the terror of the Goths, and these also fell a prey to the invaders before the end of the fourth century of the Christian era.

But the power of these wandering tribes was always liable to be paralysed by the jealousies of rival chiefs. Their notions of government were crude; hereditary succession was held of little account among them. The Huns were only formidable to their neighbours when they were under the leadership of chiefs who possessed sufficient vigour to rise pre-eminent over all others, and the talent or the craft to secure to themselves absolute power.

Attila was one of these. The Huns were already in the ascendant when he came to the throne; but his genius, energy, and insatiable ambition soon rendered them the terror of all Europe, and himself the greatest barbarian that ever wielded the sceptre. Attila had a body-guard of subject kings. His effective force has been variously estimated at half-a-million and at seven hundred thousand men. He enriched himself with the spoils of all nations; yet in the height of his barbaric pride he retained in camp the simple habits of his ancestors. Having subdued every hostile tribe within his reach, and incorporated their armies with his own, he threw the whole weight of his forces on the corrupt and degenerate Roman Empire, which was brought to the feet of the conqueror and compelled to accept conditions of peace the most degrading that the insolence of the invader could dictate.

Desolation everywhere followed the march of Attila, for destruction was ever the glory of the barbarians. As the old Huns lived by predatory warfare, so the hosts of Attila were actuated, only in a higher degree, by the savage instincts of wild beasts. But their power only held together while there was food for pillage, and a master mind to direct their enterprise. And thus their reign of terror in Europe was of brief duration. A heavy debauch cut short the career of Attila, and he died an inglorious death in his own bed from the bursting of an artery. The empire of his creation collapsed after his death amid contending factions; and in A.D. 468, just fifteen years after the death of Attila, the empire of the Huns was utterly destroyed, and their name disappeared from history.

The shepherds tended their flocks in the steppes of Tartary, and 700 years passed away before another chief arose to summon the scattered tribes to his standard. During that period sundry insignificant dynasties succeeded each other on the outskirts of the Chinese dominions. The Turks also appeared in the interval, and established a formidable power, which lasted from the sixth to the eighth century. They issued from the Altai mountains, where they had served the Geougen Tartars who had overwhelmed the Huns after the death of Attila. The Turks, or Turki, reduced the Geougen, and, it is said, almost extirpated them. These Turks have been supposed to have been identical in race with the Huns who preceded, and the Mongols who followed, them.[10] But there is much reason to doubt their consanguinity.[11] The great skill in iron working for which the original Turks were distinguished, seems sufficient to mark a difference between them and the ancestors of the pure Mongols. They shaved the beard also in token of grief, and were considered by the Persians handsome men.[12] The Huns and Mongols had almost no beard, and in the eyes of all writers who have thought it worth while to describe their persons, they were remarkable for their deformity.
