These factors range from centralized storage and redistributive econo mies, agromanagerial models, mercantile network control, confliet and conquest, conversion of military commanders into administrators, political power through monumental cosmic reproduction, and elite power through ideological change. It discusses specific archaeological data useful in theoretieal construction. In the Introduction, a discussion of different developmental processes of urban societies is made. The Eastern Anatolian example emphasizes the role played by interregional exchange networks linking the Mesopotamian plains with the Syro-Anatolian regions. The emergence of an elite is related with the control of the movement of craft goods and raw materials, more than with the appropriation of subsistence goods. The Chinese example stresses the importance of conflict provoked by demographie pressures on resources. The Mesoamerican cases relate to vast urban developments and manu facturing centers, ideological importance of monumental planning, and changing behavior of elites. The Andean cases are related either to the transformation of theocratie leadership into military administrators oe to the agricultural intensification model.
