With the exception of the Pacific coast, the Eurasian Arctic and subarctic correspond fairly precisely with the distribution of the reindeer. More than any other factor, the reindeer and its domestication lend some cultural unity to the region as a whole, as well as distinguish the region from the North American Arctic and subarctic, where the reindeer (or caribou) remains wild.

The two types of reindeer husbandry are defined by the two predominant ecosystems, the taiga and the tundra. The open terrain of the tundra permits the supervision of large herds, and these generally migrate with their herdsmen between winter pastures within the margins of the taiga and summer pastures out on the tundra. Such pastoralism therefore entails fairly extended nomadic movements, sometimes across hundreds of miles. Peoples that practice this form of husbandry include the mountain Sami and tundra Nenets in the west and the inland Chukchi and Koryak in the east. The Sami and Nenets, however, use herding dogs, whereas the eastern groups do not. Techniques of herding that involve the use of drift nets and surrounds are clearly derived from the pre-pastoral hunting of wild reindeer (still practiced in the 20th century by the Nganasan). A few trained animals are kept for transport purposes, the reindeer being harnessed to the sledge in place of the dog. But the majority of animals are kept for their meat, fat, and hides and are scarcely tame.

The taiga form of reindeer husbandry occurs on a much smaller scale, since it is impossible to supervise large herds in a forest environment. The reindeer themselves are of a larger stature and can be ridden and used as pack animals. Indeed, their primary use is for transport in an economy that is otherwise based on hunting, trapping, and fishing. The animals are therefore much more tame and are slaughtered only in case of emergency. With such a form of husbandry, the pattern of movement tends to be seminomadic. Peoples practicing this form include the forest and Skolt Sami, forest Nenets, Selkup, Ket, Evenk, and Even.

The cultures of the North Pacific coast, on both the Asian and the American sides, have a quite different economic basis. Among the coastal Asian peoples the reindeer plays no part, although reindeer products may be obtained in trade from inland peoples. Maritime hunting and fishing support relatively large, sedentary settlements, and the only domestic animals are dogs, which are harnessed in teams to pull sledges. Siberian peoples with this kind of coastal economy include the coastal Chukchi and Koryak, the Yupiit, and some Evenk and Even communities on the Okhotsk coast.

Other features of traditional cultural adaptation, such as housing and clothing, can be linked to this tripartite division between taiga, tundra, and coast. Winter dwellings in the taiga were often semi-subterranean. They were lined with timber, with walls and roof also of timber, and were often insulated with earthen sods. At temporary hunting and fishing sites, occupied in the summer months, taiga dwellers would build pyramidal or conical tents covered with birch bark (in western regions) or larch bark (in the east). The nomadic herders of the tundra lived year-round in conical tents covered with reindeer hide. Because tent poles and covers had to be carried during migrations, the size of the tent was constrained by the number of draft reindeer at a household’s disposal. Thus the tents of wealthy reindeer owners could be large and numerous, whereas poorer peoples had to be content with more meagre dwellings. In northeastern Siberia, among the reindeer-keeping Chukchi, Koryak, Yukaghir, and Even, a different type of tent was in use. This had a low, circular (but vertical) wall capped by a gently sloping, conical roof section. The covering of reindeer skin or larch bark was stretched over a frame of wooden poles. In former times, the coastal Chukchi and Yupiit lived in semi-subterranean dwellings roofed with a structure made of the jaw and rib bones of the whale and covered with earthen sods. More recently, they have lived in tents similar to those of the inland peoples, except that they may be covered with walrus hide rather than reindeer skin. The permanent dwellings of the coastal Koryak and the Itelmen are remarkable semi-subterranean structures octagonal in plan, lined with timber, and with a side entrance along a corridor for summer use and an entrance through the centre of the roof for use in winter.

Throughout the Eurasian Arctic and subarctic, the main items of clothing were made from hides and furs. The forest-dwelling peoples drew on a wide range of fur-bearing species, whereas the clothes of the tundra dwellers were made almost exclusively from reindeer hide. On the northern Pacific coast, clothes were made both from sealskin and from reindeer hide obtained in trade from the inland herding people.

Information on kinship patterns and social organization among the peoples of the Eurasian Arctic and subarctic is rather patchy. Sami kinship has been well studied and has been shown to have a bilateral structure in which equal significance is attached to relationships on both maternal and paternal sides. Local communities or camps tend to take the form of a bilateral kindred centred on a group of siblings and their spouses. This kind of community organization appears to be widespread across the Eurasian north from Lapland to the Bering Strait, and the flexibility it affords for residential affiliation holds clear adaptive advantages in an uncertain environment. Nevertheless, ethnographers have claimed to detect vestiges of patrilineal clan organization among such peoples as the Nenets, Khanty, Mansi, Nganasan, Evenk, Even, and Sakha. The origins of the clan system may lie with the pastoral peoples of the southern Siberian steppes, but with the transition to taiga and tundra environments the significance of clans appears to fade out. With the significant exception of the Sakha, all northern Eurasian peoples are politically egalitarian, and, despite individual differences in wealth and influence, there are no formal chiefly offices or institutionalized hierarchies. As for Arctic and subarctic peoples generally, a strong emphasis is placed on the value of personal autonomy.

Traditional religious belief and practice throughout the Eurasian north was shamanistic in form (indeed, the term “shaman” is of Evenk derivation). According to the shamanistic worldview, the cosmos is divided into many layers, and the shaman, who is helped or hindered by various spirits, is thought to be able to travel in trance between them and, in so doing, to achieve an integration that is essential both to the health of individuals and to the well-being of the community. The animal counterpart of the human shaman was the bear, which throughout northern Eurasia has been the object of a special cult. The various species of wild animals were believed to be controlled by spirit masters or guardians, which would “give” animals to hunters who treated them with proper respect. Domestic reindeer (and dogs, on the Pacific coast) were vehicles of propitiatory sacrifice.

The Skolt Sami were among the first of the Indigenous peoples of the north to be converted to Christianity, which was brought by the legendary Orthodox saint Trifon in 1532. Subsequently, from the 17th century, the Sami living farther to the west were subjected to Lutheran missionary influence, and their shamanistic beliefs and practices were violently eradicated. In Siberia the Eastern Orthodox church spread eastward along with Russian settlement, but Eastern Orthodoxy often secured only nominal adherence among Indigenous populations, who continued to practice their traditional religion. In the 20th century, shamanistic practices had been more rigorously suppressed but were showing signs of revival.

In modern times, the Sami of Norway, Sweden, and Finland have fared very differently from the Indigenous peoples of Russia. Although the aspirations of the Sami toward nationhood have been frustrated by their citizenship of three different states (or four, including Russia), vigorous ethnopolitical organizations have been established which have fought effectively to reverse the stigma that once was attached to Sami identity, to secure respect for their language and cultural traditions, and to assert their rights—on the basis of prior occupancy—to land and water. Materially, the Sami can enjoy the benefits, in terms of raised living standards, of their citizenship of relatively affluent welfare states; however, the Chernobyl nuclear accident of 1986, which spread radioactive material over much of northwestern Lapland, dealt a blow from which the reindeer economy may be slow to recover.

Prior to the dissolution of the Soviet Union in the early 1990s, many of the minority peoples of the northern U.S.S.R. were given formal recognition in its administrative structure. Post-Soviet Russia retains to a large degree the recognition and rights to limited autonomy of certain minorities, including the Komi, Sakha, Nenets, Khanty, Mansi, Evenk, Chukchi, and Koryak. During the Soviet era, however, all political and economic direction came from the centre. Reindeer husbandry, hunting, fishing, and trapping were all reorganized on the principles of collectivization.

The growth of mining and of oil and gas exploration in Russia has caused grave problems of environmental pollution, posing a major threat to the livelihood of Indigenous peoples. Since the late 1980s, however, with the advent of the policy of perestroika (“restructuring”) and the breakup of the Soviet Union itself, these peoples are finding a new voice with which to express their concerns and ethnic aspirations, in solidarity with other peoples of the so-called Fourth World.
