Around 4000 years ago the advanced urban civilizations in Egypt, Mesopotamia and India suddenly collapsed. What happened? Did a prolonged drought cause the breakdown of social order? Recent discoveries from all over the world strongly support the suspected link of the collapse with climate. The volume presents the findings of more than 40 researchers and provides a review on the relevant information. It appears that a major shift of the precipitation pattern affected many parts of the world at approximately the same time, with disastrous effects on the nomadic populations of Asia, Africa and...

Megadrought and Collapse is the first book to treat in one volume the current paleoclimatic and archaeological evidence of megadrought events coincident with major historical examples of societal collapse. Previous works have offered multi-causal explanations for climate change, from overpopulation, overexploitation of resources, and warfare to poor leadership and failure to adapt to environmental changes. In earlier synthetic studies of major instances of collapse, the archaeological record has often not been considered.

Included in this volume are nine case studies that span...
