The Roman empire during the period framed by the accession of Septimus Severus in 193 and the rise of Diocletian in 284 has conventionally been regarded as one of 'crisis'. Between 235 and 284, at least eighteen men held the throne of the empire, for an average of less than three years, a reckoning which does not take into account all the relatives and lieutenants with whom those men shared power. Compared to the century between the accession of Nerva and the death of Commodus, this appears to be a period of near unintelligibility. The middle of the century also witnessed catastrophic, if temporary, ruptures in the territorial integrity of the empire. At slightly different times, large portions of the eastern and western halves of the empire passed under the control of powers and principalities who assumed the mantle of Roman government and exercised meaningful and legitimate juridical, political and military power over millions. The success and longevity of those political formations reflected local responses to the collapse of Roman governmental power in the face of extraordinary pressure on its borders. Even those regions that remained Roman were subjected to depredation and pillage by invading armies. The Roman peace, which had become in the last instance the justification for empire, had been shattered. In this pioneering history Clifford Ando describes and integrates the contrasting histories of different parts of the empire and assesses the impacts of administrative, political and religious change.

This book is about the reinvention of the Roman Empire during the eighty years between the accession of Diocletian and the death of Julian.

This book deals with changing power and status relations between AD 193 and 284, when the Empire came under tremendous pressure, and presents new insights into the diachronic development of imperial administration and socio-political hierarchies between the second and fourth centuries.

A discursive look at the key debates that evolved from this period of the Roman Empire.

Between the deaths of the Emperors Julian (363) and Justinian (565), the Roman Empire underwent momentous changes. Most obviously, control of the west was lost to barbarian groups during the fifth century, and although parts were recovered by Justinian, the empire's centre of gravity shifted irrevocably to the east, with its focal point now the city of Constantinople. Equally important was the increasing dominance of Christianity not only in religious life, but also in politics, society and culture. Doug Lee charts these and other significant developments which contributed to the transformation of ancient Rome and its empire into Byzantium and the early medieval west. By emphasising the resilience of the east during late antiquity and the continuing vitality of urban life and the economy, this volume offers an alternative perspective to the traditional paradigm of decline and fall.
