As a result, Greek and Roman empires have largely been studied in isolation from those of the Near East. This volume is designed to address these deficits and encourage dialogue across disciplinary boundaries by examining the fundamental features of the successive and partly overlapping imperial states that dominated much of the Near East and the Mediterranean in the first millennia BCE and CE. A substantial introductory discussion of recent thought on the mechanisms of imperial state formation prefaces the five newly commissioned case studies of the Neo-Assyrian, Achaemenid Persian, Athenian, Roman, and Byzantine empires. A final chapter draws on the findings of evolutionary psychology to improve our understanding of ultimate causation in imperial predation and exploitation in a wide range of historical systems from all over the globe.Contributors include John Haldon, Jack Goldstein, Peter Bedford, Josef Wiesehofer, Ian Morris, Walter Scheidel, and Keith Hopkins, whose sparkling essay on Roman political economy was completed just before his death in 2004.
