Archaeologists have focused a great deal of attention on explaining the origins of village societies and the transition to a Neolithic way of life. Considerable interest has also concentrated on urbanism and the rise of the earliest cities and states. Between these two revolutions in human cultural development lie a number of organizational forms that represent less well-known phases in human social evolution. In this volume we attempt to arrive at a more thorough understanding of one such intermediate social formation: aggregated settlements.
