This volume contains the papers of the tenth annual University of Chicago Oriental Institute Postdoc Seminar on “The Early/Middle Bronze Age Transition in the Ancient Near East: Chronology, C14, and Climate Change. The seminar brought together specialists from various fields, including Egyptology, Near Eastern archaeology, radiocarbon dating and Assyriology. The articles in this volume discuss the complex interconnection between the rapid climate change around 2200 BC and societal collapses throughout the ancient Near East in the mid-late third millennium BC. A reassessment of this crucial period in Near Eastern history became necessary as radiocarbon dating projects conclusively showed that the Early Bronze Age chronology has to be raised considerably. Part I raises questions of urbanism and its demise in the Early Bronze Age southern, central, and northern Levant. Part II discusses issues of the collapse of the Akkad empire and how it might be connected to the rapid climate change around 2200 BC. Part III (Egypt) focuses on the end of the Egyptian Old Kingdom, and questions of absolute calendrical dates, but also presents a reassessment of Egyptian texts and toponyms based on the new radiocarbon chronology for the Early Bronze Age Levant. Part IV sets the topic into the wider context of the late third millennium Eastern Mediterranean. It is hoped that the present volume will serve as a concise reference for this crucial period in the coming years.
