Tribal

Classification

In fact, there is no absolute necessity for a tribal stage as defined by Sahlins and Service, no necessity, that is, for such a stage to appear in the transit from a single settlement with embedded political organization, to a complex-state structured polity. Such a developmental process could have gone on within a unit that we may conceptualize as a city-state, such a unit as Jericho might have become in its later stages ... tribalism can be viewed as reaction to the formation of complex political structure rather than a necessary preliminary stage in its evolution.
