A band society, sometimes called a camp, or in older usage, a horde, is the simplest form of human society. A band generally consists of a small kin group, no larger than an extended family or clan. The general consensus of modern anthropology sees the average number of members of a social band at the simplest level of foraging societies with generally a maximum size of 30 to 50 people. Origins of usage in anthropology Band was one of a set of three terms employed by early modern ethnography to analyse aspects of hunter-gatherer foraging societies. The three were respectively 'horde,' 'band', and 'tribe'. The term 'horde', formed on the basis of a Turkish/Tatar word úrdú (meaning 'camp'), was inducted from its use in the works of J. F. McLennan by Alfred William Howitt and Lorimer Fison in the mid-1880s to describe a geographically or locally defined division within a larger tribal aggregation, the latter being defined in terms of social divisions categorized in terms of descent. Their idea was then developed by A. R. Radcliffe-Brown, as a model for all Australian indigenous societies, the horde being defined as a group of parental families whose married males all belonged to the one patrilineal clan. 'Horde' from the outset bore stereotypical connotations of Australian Aboriginal societies as primitive, closed, rigid and simple, and came to be discarded not only for its implication of 'swarming savages' but also because it suggested a fixed tribal-territorial entity which compromised the actual field data, the field data allowing for a far more fluid concept of the group. In 1936, Julian Steward reformulated Radcliffe Brown's highly restrictive definition, by proposing the idea of a band society at the hunter-gatherer level which could be patrilineal, matrilineal or a composite of both. Over time, 'band' has tended to replace the earlier word 'horde' as more extensive comparative work on hunter-gatherer societies shows they are not classifiable as simply closed patrilineal groups, and better approached in terms of a notion of a flexible, non-exclusive social band, having bilateral relations for marriage and other purposes with similar groups in a circumscribed territory. In 1962, Les Hiatt invalidated Radcliffe-Brown's theory of the horde, demonstrating that the empirical evidence from Aboriginal societies contradicted Radcliffe-Brown's generalisations. The word "band" is also used in North America, for example among the indigenous peoples of the Great Basin. With African hunter-gatherers, for instance among the Hadza,
