Herding societies are in many respects the direct opposite of forest horticulturalists. They are usually the most nomadic of primitive societies, they occupy arid grasslands rather than rainforests, they have a nearly total commitment to their animals, and their sociopolitical system is nearly always that of a true hierarchical chiefdom rather than of egalitarian villages and tribal segments.
A society largely committed to herding has military advantages that a settled agricultural society does not have. If military power is important to survival, it will increase the commitment to the herding specialization, mainly because of the advantage conferred by mobility. This increased commitment, however, will result in the gradual loss of certain previously acquired material developments such as weaving, metalworking, pottery, substantial housing and furniture, and, of course, variety in the diet. Wealth is a burden in such societies. Successful nomadic pastoralists normally have some kind of symbiotic relationship to a settled society in order to acquire goods they cannot produce themselves. The symbiosis may be through peaceful trade. But often the military advantage of the pastoralists has led to raiding rather than exchange.
The best known and purest pastoral nomads are found in the enormous arid belt from Morocco to Manchuria, passing through North Africa, Arabia, Iran, Turkistan, Tibet, and Mongolia. They include peoples as diverse as the Arabized North Africans and the Mongol hordes. Other less specialized and successful pastoralists include the Siberian reindeer herders, cattle herders of the grasslands of north-central Africa, and the Khoekhoe and Herero of southern Africa.
Classic, full pastoralism with its powerful equestrian warriors seems to have developed around 1500 to 1000 bc in inner Asia. This relatively late full-scale pastoralist specialization may have resulted from population pressure. Horticulture mixed with domestication of animals seems to have predominated until even the least cultivable zones were filled. When warfare became endemic in such zones, many groups were forced to become fully nomadic in the arid grasslands. They might have been the losers, pushed out of their homelands, only to discover later the military power that accrued to the pastoral way of life. Thus, the victims became victors.
The full pastoralism of inner Asia requires the care of animals—including varying combinations of horses, cattle, camels, sheep, and goats—kept in ecological balance with grazing conditions over an enormous area. In some regions, however, the people may depend on a single animal species. In Arabia it is the camel (although most tribes in Arabia or North Africa also keep horses), and in east-central Africa some peoples specialize exclusively in cattle. Among these there is sometimes found a complete symbiosis between a tribe of herders and an adjacent tribe of horticulturalists to the point that they resemble a single society composed of two specialized castes, the herders occupying the superior position.
There are many part-time herding societies and many that have merely borrowed herding techniques. The reindeer breeders of the Siberian tundra have learned to apply to reindeer some of the methods of the horsemen farther south, but hunting remains their main subsistential activity. In the Argentine pampas, Indians learned to domesticate and ride the Spanish horse, which they used to hunt the rhea bird and the wild herds of Spanish cattle. The Navajo and other Indians of the American Southwest have exploited the sheep brought in originally by Spaniards, but mostly as a source of wool for blanket and rug weaving. Llamas and alpacas were domesticated in the South American Andes, but no independent pastoral society ever emerged there.
Fully committed pastoralists manifest a considerable degree of cultural uniformity. In economics, social organization, political order, and even in religion, their livelihood with its functional requirements has ironed out what must have been considerable cultural differentiation among such disparate peoples as Mongols, Arabs, and African Negroes.
The wanderings imposed on pastoralists by the necessities of forage and water tend to be cyclical and to follow long-established routes. The cycles are usually seasonal: to the lowlands in winter, to highlands in summer in temperate zones, to more arid areas in the wet season, to more watered regions in the dry season, and so on. Frequently the seasonal moves are accompanied by cultural and organizational changes. For example, a large group may draw together to pass through hostile territory and disperse later when in their own land; frequently the lush (normally wet) season brings the pastoralists together for ceremonies, trade, and fun, while the dry season requires dispersion and arduous work (as in digging deep wells to water the animals). Anthropologists call such established cyclical movements “transhumance orbits.”
Since pastoralists live in so many different environments and since even the same society varies from season to season and in response to wider spaced drought cycles, it is reasonable to expect great variations in population density. These factors, of course, affect political organization. Nomadic pastoralism lends itself to wide fluctuations in the size of political units, political cohesion, and degree of centralization.
The elementary unit of organization is the patrilineally extended family, frequently an elder patriarch and his sons and their families. In addition, if some degree of primogeniture (i.e., the eldest son inheriting most of the decision-making power for the group) prevails, and if it is extended to include other groups in terms of putative birth order and patrilineal descent, the basis of the pastoral social organization is established. This social structure has been called the “conical clan” (for its hierarchical shape). It is a characteristic social organization of chiefdoms everywhere. Its capacity for waxing and waning, fusion and fission, has obvious advantages, especially when a brief makeshift political ordering of a very large horde is militarily necessary. But the large organizations cannot maintain themselves for very long, since they easily split into their parts.
It has been noted that herders are likely to raid settled villages. But herders frequently raid each other as well. Livestock is wealth and can be exchanged for other forms of wealth—including wives. Stock raiding, like most forms of aggression, has two facets: one seems to be to replenish one’s wealth at a stranger’s expense; the other is to warn strangers against encroachment. But a raid frequently leads to retaliation and then to counterretaliation, until such raiding societies gradually become hereditary enemies.
The militarism of herding societies has played a major role in history. As wealthy agricultural civilizations developed in the Fertile Crescent of the ancient Middle East, in the Indus River Valley, and at the middle bend of the Huang Ho in China, they became easy prey for nomads. Indeed, it is likely that urbanization was stimulated for defensive reasons because of the dangers posed by nomads. These dangers may also have stimulated the formation of legal and governmental institutions in sedentary societies threatened by the pastoral raiders.
To the extent that pastoral nomadic societies achieve wealth and success in herding and in war, they tend to solidify and extend their chiefdom structure. They also add to their religious organization a hierarchical principle together with the content known as ancestor worship. Much of the mythology by which a primitive people explains itself and its customs comes in this way to have an ingredient familiar to readers of the Old Testament—the lengthy story of who begat whom and in what order.
Increased dependence on herds, particularly dependence on one particular species, such as cattle, horses, or camels, is reflected in much of the ideological and ritual content of religion. Sometimes the significance of herding leads not only to the glorification of herds and herding but even to a religious taboo against planting. Some Mongols, so quintessentially pastoral, believe that plowing and planting defile the earth spirit. Among the Nuer, as among other African cattle herders, horticulture may be practiced in time of need, but it is considered degrading toil whereas herding is a very prideful occupation. The ethnologist of the Nuer, E.E. Evans-Pritchard, wrote:
Elman R. ServiceThey are always talking about their beasts. I used sometimes to despair that I never discussed anything with the young men but livestock and girls, and even the subject of girls led inevitably to that of cattle.
