Civil war and usurpation were endemic to the later Roman Empire, with no fewer than 37 men claiming imperial power between 284 and 395 AD. This volume constructs the first comprehensive history of civil war in this period through the ways in which successive dynasties manipulated history to legitimate themselves and to discredit their predecessors.

With The Emperor and the Army in the Later Roman Empire, AD 235–395 Mark Hebblewhite offers the first study solely dedicated to examining the nature of the relationship between the emperor and his army in the politically and militarily volatile later Roman Empire. Bringing together a wide range of available literary, epigraphic and numismatic evidence he demonstrates that emperors of the period considered the army to be the key institution they had to mollify in order to retain power and consequently employed a range of strategies to keep the troops loyal to their cause. Key to these efforts were imperial attempts to project the emperor as a worthy general (imperator) and a generous provider of military pay and benefits. Also important were the honorific and symbolic gestures each emperor made to the army in order to convince them that they and the empire could only prosper under his rule.

'Emperors and Usurpers' is a history of the Roman period from the accession of Valentinian in 364 to the death of Marcian in 457, a period of turbulence and radical change, by the end of which the empire had fragmented.

One of the great maxims of history is that it is written by the victors, and nowhere does this find greater support than in the later Roman Empire. Between 284 and 395 AD, no fewer than 37 men claimed imperial power, though today we recognize barely half of these men as 'legitimate' rulers and more than two thirds died at their subjects' hands. Once established in power, a new ruler needed to publicly legitimate himself and to discredit his predecessor: overt criticism of the new regime became high treason, with historians supressing their accounts for fear of reprisals and the very names of defeated emperors chiselled from public inscriptions and deleted from official records. In a period of such chaos, how can we ever hope to record in any fair or objective way the history of the Roman state? Emperors and Usurpers in the Later Roman Empire is the first history of civil war in the later Roman Empire to be written in English and aims to address this question by focusing on the various ways in which successive imperial dynasties attempted to legitimate themselves and to counter the threat of almost perpetual internal challenge to their rule. Panegyric in particular emerges as a crucial tool for understanding the rapidly changing political world of the third and fourth centuries, providing direct evidence of how, in the wake of civil wars, emperors attempted to publish their legitimacy and to delegitimize their enemies. The ceremony and oratory surrounding imperial courts too was of great significance: used aggressively to dramatize and constantly recall the events of recent civil wars, the narratives produced by the court in this context also went on to have enormous influence on the messages and narratives found within contemporary historical texts. In its exploration of the ways in which successive imperial courts sought to communicate with their subjects, this volume offers a thoroughly original reworking of late Roman domestic politics, and demonstrates not only how history could be erased, rewritten, and repurposed, but also how civil war, and indeed usurpation, became endemic to the later Empire.

Imagining Emperors in the Later Roman Empire offers new critical analysis of the textual depictions of a series of emperors in the fourth century within overlapping historical, religious and literary contexts.

This historical commentary examines books 79(78)-80(80) of Cassius Dio's Roman History, which cover the period from the death of Caracalla in A. D. 217. to the reign of Severus Alexander and Cassius Dio's retirement from political life in 229. Cassius Dio, a Roman Senator, provides a valuable eyewitness account of this turbulent period, which was marked by the assassination of Caracalla, the rise of Macrinus, Rome's first equestrian emperor, and his subsequent overthrow, the tempestuous, and by all accounts peculiar, reign of Elagabalus, and the continuation of the Severan dynasty under the young Severus Alexander. In addition to elucidating important passages from these books, this study assesses Cassius Dio's political life and its relationship to his literary career; his call to history and time of composition; his historical method; and his attitude toward and subsequent presentation of the later Severan dynasty. In its investigation of books 79(78)-80(80), the work assesses an important stretch of Dio's actual text, which for other parts has been preserved largely in epitome and excerpts. Finally, the work aims to fill a gap in scholarship, as no commentary on these books of Cassius Dio's history has been produced since the nineteenth century, and its publication coincides with a renewed interest in the history and historiography of the Severan period.
