The Collapse of Complex Societies by Wikipedia:Joseph Tainter. Cambridge: Cambridge University Press. ISBN 0-521-38673-X. (1990). (1st paperback ed.).


Any explanation of political collapse carries lessons not just for the study of ancient societies, but for the members of all complex societies in both the present and future. Dr Tainter describes nearly two dozen cases of collapse and reviews more than 2000 years of explanations. He then develops a new and far-reaching theory that accounts for collapse among diverse kinds of societies, evaluating his model and clarifying the processes of disintegration by detailed studies of the Roman, Mayan and Chacoan collapses.

Tainter argues that societies collapse when their investments in social complexity reach a point of diminishing marginal returns. According to Tainter, societies become more complex as they try to solve problems. Social complexity can include differentiated social and economic roles, reliance on symbolic and abstract communication, and the existence of a class of information producers and analysts who are not involved in primary resource production. Such complexity requires a substantial "energy" subsidy (meaning resources, or other forms of wealth). When a society confronts a "problem," such as a shortage of or difficulty in gaining access to energy, it tends to create new layers of bureaucracy, infrastructure, or social class to address the challenge. Eventually, this cost grows so great that any new challenges such as invasions and crop failures cannot be solved by the acquisition of more territory. At that point, the empire fragments into smaller units.
