The remains of a complex stone- walled encampment at //Khauxa!nas in Namibia provide new insights into the social consequences of European contact with the pastoral Khoi. The Namibian evidence contradicts the general view that the eighteenth- century Khoi were little more than a colonial underclass. Details of layout and construction from //Khauxa!nas point to the rise of a hierarchical organization uniting autonomous households within a pastoral alliance. This development reflects the evolutionary potential of Khoi society at a crucial moment in its history, immediately prior to the rise of armed resistance against colonial rule. Keywords: pastoralism, spatial organization, contact, Khoi, Namibia.
