It is one of the great mysteries in the archaeology of the Americas: the depopulation of the northern Southwest in the late thirteenth-century AD. Considering the numbers of people affected, the distances moved, the permanence of the departures, the severity of the surrounding conditions, and the human suffering and culture change that accompanied them, the abrupt conclusion to the farming way of life in this region is one of the greatest disruptions in recorded history.

Much new paleoenvironmental data, and a great deal of archaeological survey and excavation, permit the fifteen scientists represented here much greater precision in determining the timing of the depopulation, the number of people affected, and the ways in which northern Pueblo peoples coped—and failed to cope—with the rapidly changing environmental and demographic conditions they encountered throughout the 1200s. In addition, some of the scientists in this volume use models to provide insights into the processes behind the patterns they find, helping to narrow the range of plausible explanations.

What emerges from these investigations is a highly pertinent story of conflict and disruption as a result of climate change, environmental degradation, social rigidity, and conflict. Taken as a whole, these contributions recognize this era as having witnessed a competition between differing social and economic organizations, in which selective migration was considerably hastened by severe climatic, environmental, and social upheaval. Moreover, the chapters show that it is at least as true that emigration led to the collapse of the northern Southwest as it is that collapse led to emigration.

Is wealth inequality a universal feature of human societies, or did early peoples live an egalitarian existence? How did inequality develop before the modern era? Did inequalities in wealth increase as people settled into a way of life dominated by farming and herding? Why in general do such disparities increase, and how recent are the high levels of wealth inequality now experienced in many developed nations? How can archaeologists tell?

Ten Thousand Years of Inequality addresses these and other questions by presenting the first set of consistent quantitative measurements of ancient wealth inequality. The authors are archaeologists who have adapted the Gini index, a statistical measure of wealth distribution often used by economists to measure contemporary inequality, and applied it to house-size distributions over time and around the world. Clear descriptions of methods and assumptions serve as a model for other archaeologists and historians who want to document past patterns of wealth disparity.

The chapters cover a variety of ancient cases, including early hunter-­gatherers, farmer villages, and agrarian states and empires. The final chapter synthesizes and compares the results. Among the new and notable outcomes, the authors report a systematic difference between higher levels of inequality in ancient Old World societies and lower levels in their New World counterparts.

For the first time, archaeology allows humanity’s deep past to provide an account of the early manifestations of wealth inequality around the world.
