10.1 Northern tribes
Harsh territory abounded across the top of Eurasia. In the far north the bleak, open wilderness of the tundra stretched in a thin strip from Scandinavia to Siberia; immediately to its south lay a wider band of forest, the taiga. This Arctic territory was populated mostly by hunters like the Yukagir of northern Siberia and by reindeer pastoralists like the Lapps of northern Scandinavia.
But between this northern world and the civilizations far to the south lay the Eurasian steppes, reaching Manchuria in the east and Hungary in the west. Like the uplands of Persia, this belt of grasslands did not bear fine fruits. But it was the homeland of the horse and doubtless the scene of its domestication. Already in the time of Cyrus the steppes were teeming with nomadic pastoralists. These pastoralists were hard men, and those whose economies were built around the horse had military advantages.
A Latin author of the fifth century A.D. had this to say of one such people, the Huns, who at the time were invading the western Roman Empire: "Scarce has the infant learned to stand without his mother's aid when a horse takes him on his back. You would think the limbs of man and horse were born together, so firmly does the rider always stick to the horse, just as if he were fastened to his place: any other folk is carried on horseback, this folk lives there."
Nomadic pastoralists were supremely mobile. Scholars dither as to whether or not to identify the Huns with the Hsiung-nu who threatened the northern frontier of China starting in the late third century B.C. But it is a matter of record that in the thirteenth century A.D. the Mongols attacked both Germany and Japan.
The earliest people of the steppes to have a serious impact on the outside world were probably the Indo-Europeans, though they were by no means exclusively pastoralists. In our survey of the regional civilizations of Eurasia we repeatedly encountered peoples speaking languages of the Indo- European family; already in ancient times such languages could be found as far afield as the British Isles and northeastern India, and the fact that they constitute a family means that they must go back to a single ancestral language—"proto- Indo- European."
Some of the ancient expansion of the Indo-European languages took place as late as the first millennium B.C., but a good deal of it must be older. One set of clues is linguistic. Though we have no direct knowledge of the ancestral language, it is possible to reconstruct some of its vocabulary by the systematic analysis of common elements in the vocabularies of the known daughter languages (screening out later loanwords in the process). Such reconstruction points to an economy in which farming was well developed, especially on the pastoral side, where it included the domesticated horse; wheeled vehicles were certainly in use, but such metallurgy as existed may have been limited to copper as opposed to bronze.
From an archaeological point of view the most diagnostic elements are the domesticated horses and the wheeled vehicles. The horse must surely have been domesticated somewhere in its natural range; this takes us to the steppes, where both the domesticated horse and the cart make their appearance in the archaeological record in the fourth millennium B.C., prior to the onset of the Bronze Age. Within the steppes there is reason to pick out the region to the north of the Caspian and Black Seas as the most likely Indo-European homeland. All this can only be a hypothesis, but it is undoubtedly the best available. What is satisfying about it is that it also provides us with a measure of explanation of the Indo- European expansion that must have followed in the third millennium. A people whose way of life includes horses and carts is mobile, and at the same time it has a military advantage over pedestrian peoples, whom it is liable to push aside or assimilate.
Yet, of all the steppe peoples of history, only the Mongols came close to creating a Eurasian empire. Their highly destructive conquests in the thirteenth century A.D. included large parts of East Asia, the Near East, and eastern Europe (the lack of steppe to the west of Hungary does something to explain their failure to push on into western Europe). In the end, however, their imperial venture came to nothing. The far-flung Mongol empire lasted only a few decades; already in the thirteenth century, it was divided into increasingly autonomous states, and most of these disappeared in the course of the fourteenth century. Just as signifpent is the fact that the Mongols had brought no civilization to spread among their battered subjects, tending rather toward eventual assimilation into the local milieu. In the end, the cultural map of Eurasia after the Mongols did not look very different from what it had been before.
There was, however, one thing the Mongols did for Eurasia. For a period of a few decades, after their initial conquests and before the disintegration of their states, the Mongols made it possible for people to travel from one end of Eurasia to the other. Thus the Christian monk Rabban Sauma, born into a Turkish people living on the northern frontier of China, found his way from Peking to Bordeaux, while the Venetian merchant Marco Polo traveled to China with his father and uncle and found employment in the service of the Mongol ruler there. This mobility was not an unmixed blessing—it probably helped to spread a vicious epidemic of plague from one end of Eurasia to the other in the middle of the fourteenth century. But it did provide an unprecedented opportunity for the civilizations of Eurasia to learn more about each other. In Iran, for example, it became possible in Mongol times for a reader of Persian to consult systematic accounts of the histories of China and western Europe (see figure 23; that everyone looks oriental reflects the strength of Chinese artistic influence in Iran in this period). We will come back to the implications of this widening of Eurasian horizons in the next chapter.
