The fourth century, the century of Constantine, witnessed the foundation and rise of a new relationship between the Roman Empire and the Arabs. The warrior Arab groups in Oriens became foederati, allies of Byzantium, the Christian Roman empire, and so they remained until the Arab conquests. In Byzantium and the Arabs in the Fourth Century, Irfan Shahîd elucidates the birth of the new federation and the rise of its institutional forms and examines the various constituents of federate cultural life: the phylarchate, the episcopate, the beginnings of an Arab Church, an Arabic liturgy, and the earliest attested composition of Arabic poetry. He discusses the participation of the Arab foederati in Byzantium’s wars with her neighbors—the Persians and the Goths—during which those Arab allies, most notably the Tanūkhids, contributed to the welfare of the imperium and the ecclesia. In the reign of Valens, the foederati appeared as the defenders of Nicene Orthodoxy: their soldiers fought for it; their stern and uncompromising saint, Moses, championed it; and their heroic and romantic queen, Mavia, negotiated for it.

The De Administrando Imperio, compiled by Constantine VII Porphyrogenitus in the tenth century, is one of the most important historical documents surviving from the middle Byzantine period, containing a wide variety of information on foreign relations and internal administration. The critical text of the De Administrando Imperio, edited by Gyula Moravcsik and translated by R. J. H. Jenkins (Dumbarton Oaks Texts), is now joined by the commentary, written in 1962 by a team of eminent scholars led by Jenkins. Long out of print, the Jenkins commentary remains the most thorough and authoritative study of this significant medieval text, and it is now republished as a companion volume to the critical text and translation. In addition to extensive commentary on the historical, geographical, and philological nuances of the Greek text, this volume contains a bibliography, map, indexes, and genealogical charts.

This is a reprint of the second revised edition of the text and translation of the De Administrando Imperio written and compiled by Emperor Constantine VII Porphyrogenitus in the tenth century. It contains a wide variety of information on both foreign relations and internal administration and is one of the most important historical documents surviving from the Middle Byzantine period. Its confidential character and generally honest appraisal of the empire’s political situation enhance its value for students of Byzantium and Europe during this period. The edition includes general and critical introductions, an index of proper names, and an extensive glossary, as well as grammatical notes and an index of sources and parallel passages.

The era of late antiquity—from the middle of the third century to the end of the eighth—was marked by the rise of two world religions, unprecedented political upheavals that remade the map of the known world, and the creation of art of enduring glory. In these eleven in-depth essays, drawn from the award-winning reference work Late Antiquity: A Guide to the Postclassical World, an international cast of experts provides essential information and fresh perspectives on this period's culture and history.

A comprehensive new history of the Eastern Roman Empire based on the science of the human past.

As modern empires rise and fall, ancient Rome becomes ever more significant. We yearn for Rome’s power but fear Rome’s ruin—will we turn out like the Romans, we wonder, or can we escape their fate? That question has obsessed centuries of historians and leaders, who have explored diverse political, religious, and economic forces to explain Roman decline. Yet the decisive factor remains elusive.

In New Rome, Paul Stephenson looks beyond traditional texts and well-known artifacts to offer a novel, scientifically minded interpretation of antiquity’s end. It turns out that the descent of Rome is inscribed not only in parchments but also in ice cores and DNA. From these and other sources, we learn that pollution and pandemics influenced the fate of Constantinople and the Eastern Roman Empire. During its final five centuries, the empire in the east survived devastation by natural disasters, the degradation of the human environment, and pathogens previously unknown to the empire’s densely populated, unsanitary cities. Despite the Plague of Justinian, regular “barbarian” invasions, a war with Persia, and the rise of Islam, the empire endured as a political entity. However, Greco-Roman civilization, a world of interconnected cities that had shared a common material culture for a millennium, did not.

Politics, war, and religious strife drove the transformation of Eastern Rome, but they do not tell the whole story. Braiding the political history of the empire together with its urban, material, environmental, and epidemiological history, New Rome offers the most comprehensive explanation to date of the Eastern Empire’s transformation into Byzantium.

In this highly original work, Christopher Kelly paints a remarkable picture of running a superstate. He portrays a complex system of government openly regulated by networks of personal influence and the payment of money. Focusing on the Roman Empire after Constantine's conversion to Christianity, Kelly illuminates a period of increasingly centralized rule through an ever more extensive and intrusive bureaucracy.

The book opens with a view of its times through the eyes of a high-ranking official in sixth-century Constantinople, John Lydus. His On the Magistracies of the Roman State, the only memoir of its kind to come down to us, gives an impassioned and revealing account of his career and the system in which he worked. Kelly draws a wealth of insight from this singular memoir and goes on to trace the operation of power and influence, exposing how these might be successfully deployed or skillfully diverted by those wishing either to avoid government regulation or to subvert it for their own ends. Ruling the Later Roman Empire presents a fascinating procession of officials, emperors, and local power brokers, winners and losers, mapping their experiences, their conflicting loyalties, their successes, and their failures.

This important book elegantly recaptures the experience of both rulers and ruled under a sophisticated and highly successful system of government.
