The emperor Theodosius I (AD 379–395) was one of the most remarkable figures of the late antique period. In the face of religious schism, political turmoil, and barbarian threats he managed to maintain imperial power and forge a political dynasty that would dominate both east and west for over half a century. This study, the first English language biography in over twenty years, traces his rise to power and tumultuous reign, and examines his indelible impact on a rapidly changing empire.

The division of the late Roman Empire into two theoretically cooperating parts by the brothers Valentinian and Valens in 364 deeply influenced many aspects of government in each of the divisions. Although the imperial policies during this well-documented and formative period are generally understood to have been driven by the religious and ideological aims of the emperors, R. Malcolm Errington argues that the emperors were actually much more pragmatic in their decision making than has previously been assumed. The division of responsibilities between the emperors inevitably encouraged separate developments and allowed locally varying and often changing imperial attitudes toward different forms of religious belief. Errington demonstrates that the main stimulus for action in this period nearly always came from below the level of the imperial government, and not from an imperial initiative. Extending the theory of Fergus Millar into the later empire, Errington argues that the emperors were fundamentally reactive to regionally supplied information, as Millar has asserted was the case for the High Empire. Thus, despite significant structural changes, the empire remained broadly traditional in its operations.

An integrated collection of essays examining the politics, social networks, law, historiography, and literature of the later Roman world. The volume treats three central themes: the first section looks at political and social developments across the period and argues that, in spite of the stress placed upon traditional social structures, many elements of Roman life remained only slightly changed. The second section focuses upon biographical texts and shows how late-antique authors adapted traditional modes of discourse to new conditions. The final section explores the first years of the reign of Theodosius I and shows how he built upon historical foundations while unfurling new methods for utilising, presenting, and commemorating imperial power. These papers analyse specific events and local developments to highlight examples of both change and continuity in the Roman world from 284-450.

Gibbon offers an explanation for why the Roman Empire fell, a task made difficult by a lack of comprehensive written sources, though he was not the only historian to tackle the subject. Most of his ideas are directly taken from what few relevant records were available: those of the Roman moralists of the 4th and 5th centuries.

A sweeping political history of the turbulent two centuries that led to the demise of the Roman Empire. The Tragedy of Empire begins in the late fourth century with the reign of Julian, the last non-Christian Roman emperor, and takes readers to the final years of the Western Roman Empire at the end of the sixth century. One hundred years before Julian’s rule, Emperor Diocletian had resolved that an empire stretching from the Atlantic to the Euphrates, and from the Rhine and Tyne to the Sahara, could not effectively be governed by one man. He had devised a system of governance, called the tetrarchy by modern scholars, to respond to the vastness of the empire, its new rivals, and the changing face of its citizenry. Powerful enemies like the barbarian coalitions of the Franks and the Alamanni threatened the imperial frontiers. The new Sasanian dynasty had come into power in Persia. This was the political climate of the Roman world that Julian inherited. Kulikowski traces two hundred years of Roman history during which the Western Empire ceased to exist while the Eastern Empire remained politically strong and culturally vibrant. The changing structure of imperial rule, the rise of new elites, foreign invasions, the erosion of Roman and Greek religions, and the establishment of Christianity as the state religion mark these last two centuries of the Empire.
