This volume looks at 'visions of community' in a comparative perspective, from Late Antiquity to the dawning of the age of crusades. It addresses the question of why and how distinctive new political cultures developed after the disintegration of the Roman World, and to what degree their differences had already emerged in the first post-Roman centuries. The Latin West, Orthodox Byzantium and its Slavic periphery, and the Islamic world each retained different parts of the Graeco-Roman heritage, while introducing new elements. For instance, ethnicity became a legitimizing element of rulership in the West, remained a structural element of the imperial periphery in Byzantium, and contributed to the inner dynamic of Islamic states without becoming a resource of political integration. Similarly, the political role of religion also differed between the emerging post-Roman worlds. It is surprising that little systematic research has been done in these fields so far. The 32 contributions to the volume explore this new line of research and look at different aspects of the process, with leading western Medievalists, Byzantinists and Islamicists covering a wide range of pertinent topics. At a closer look, some of the apparent differences between the West and the Islamic world seem less distinctive, and the inner variety of all post-Roman societies becomes more marked. At the same time, new variations in the discourse of community and the practice of power emerge. Anybody interested in the development of the post-Roman Mediterranean, but also in the relationship between the Islamic World and the West, will gain new insights from these studies on the political role of ethnicity and religion in the post-Roman Mediterranean.

"Empires are not an under-researched topic. Recently, there has been a veritable surge in comparative and conceptual studies, not least of pre-modern empires. The distant past can tell us much about the fates of empires that may still be relevant today, and contemporary historians as well as the general public are generally aware of that. Tracing the general development of an empire, we can discern a kind imperial dynamic which follows the momentum of expansion, relies on the structures and achievements of the formative period for a while, and tends to be caught in a downward spiral at some point. Yet single cases differ so much that a general model is hardly ever sufficient.There is in fact little consensus about what exactly constitutes an empire, and it has become standard in publications about empires to note the profusion of definitions.Some refer to size-for instance, 'greater than a million square kilometers', as Peter Turchin suggested. Apart from that, many scholars offer more or less extensive lists of qualitative criteria. Some of these criteria reflect the imperial dynamic, for instance, the imposition of some kind of unity through 'an imperial project', which allows moving broad populations 'from coercion through co-optation to cooperation and identification'"--

The papers collected in this volume provide invaluable insights into the results of different interactions between “Romans” and Others. Articles dealing with cultural changes within and outside the borders of Roman Empire highlight the idea that those very changes had different results and outcomes depending on various social, political, economic, geographical and chronological factors. Most of the contributions here focus on the issues of what it means to be Roman in different contexts, and show that the concept and idea of Roman-ness were different for the various populations that interacted with Romans through several means of communication, including political alliances, wars, trade, and diplomacy. The volume also covers a huge geographical area, from Britain, across Europe to the Near East and the Caucasus, but also provides information on the Roman Empire through eyes of foreigners, such as the ancient Chinese.

The Roman army represented an important social and organizational reference model for the Romano-Barbarian societies, which progressively replaced the Western Empire in the transition from Late Antiquity to Early Middle Ages. The great flexibility of the decision-making and organizational solutions used by the Roman army allowed the ‘new lords’ to readapt them and thus maintain power in early medieval Europe for a long time. From a perspective ranging from political, social and economic history to law, anthropology, and linguistic, this book demonstrates how interesting and fruitful the investigation of this specific cultural imprint can be in order to gain a better understanding of the origins of the civilization that arouse after the fall of the Roman world. Contributors are Francesco Borri, Fabio Botta, Francesco Castagnino, Stefan Esders, Carla Falluomin, Stefano Gasparri, Wolfgang Haubrichs, Soazick Kerneis, Luca Loschiavo, Valerio Marotta, Esperanza Osaba, Walter Pohl, Jean-Pierre Poly, Pierfrancesco Porena, Iolanda Ruggiero, Andrea Trisciuoglio, Andrea A. Verardi, and Ian Wood.

This book looks at the fall and persistence of empires from the perspective of the powers that replaced them, and compares several cases between China and the West in the first millennium CE with surprisingly similar beginnings and different outcomes.

Christians Shaping Identity explores different ways in which Christians constructed their own identity and that of the society around them to the 12th century C.E. It also illustrates how modern readings of that past continue to shape Christian identity.
