Great changes have taken place in the approach of historians to the topic since the publication of East of Byzantium (1980). Instead of centre-periphery or top-down models they now see the relations between Byzantium and the east in terms of connectivity, networks and horizontal ties. This is connected with the spread of late antiquity as a concept and includes a great expansion in Syriac studies. Late antiquity now embraces the emergence of Islam and looks towards Eurasia; another challenge is posed by the rise of global history. But these developments, with the new focus on the fall of the western empire, raise major problems of identity for Byzantium itself, and indeed for western Europe.

Cities seem to form when state population surpasses 10,000. Over 5000 years, top city populations have remained 0.1−0.5% of world population. The square root law of city population: The largest city population tends to be hundred times the square root of state population. This law held from 3000 BCE to 1800 CE. Constantinople exemplifies it from 400 to 1800. It no longer holds, as the economic reach of major cities surpasses international borders.

This chapter addresses the subject of sex in Constantinople in the sixth century CE, the heart of the Eastern Roman Empire. It draws on a range of rich evidence. A fundamental starting point is provided by the writings of the contemporary historian Procopius, in particular his comments in Secret History on the life and deeds of the empress Theodora, wife of the emperor Justinian I (527–565), who was an actress before marrying her husband. In addition it draws on the legislation of the emperor Justinian, the chronicle of John Malalas, erotic epigrams of the period, and Christian ascetic literature. From these writings strong ideals of right and wrong sexual behaviour emerge, revealing both traditional Roman values and the increasing Christianisation of society. This can create the impression that sexual activity was very tightly controlled, especially prostitution, extra-marital sex, and same-sex sex. However, it is apparent that life was less clear-cut. Justinian himself recognized that desire was a powerful impulse and that people did ‘sin’. It is also evident that people could enjoy thinking about illicit sex, and engage in it enthusiastically. Ironically, overtly Chistian texts could even incite the desire they sought to neutralize.

This chapter explores the displacement of knowledge following the First World War in two ways. First, it focuses on the displacement of people, specifically the Russian refugees displaced by the civil war in the early 1920s. It shows how thousands of intellectuals were combed out of the wider body of displaced people and relocated in sites across Europe and the wider world. Second, the chapter looks at how other forms of intellectual capital were displaced following post-war treaties and the redrawing of international borders, such as Hungarian institutions that found themselves ‘displaced’ in Czechoslovakia and Romania. Arguments about the displacement of knowledge demonstrated how individuals, institutions, and even modes of thinking were portrayed as synonymous with certain national identities in order to effect political change. The chapter explores the tension between the nationalization of knowledge and its simultaneous claims to universalism.

This chapter argues that the military and political history and prosopography of the early fifth century cannot be reconciled with the existence of the Notitia system. Specifically, the military challenges the east Roman empire faced during this period, most notably Alaric’s depredations in the Balkans, Gaïnas’ revolt in Asia Minor, and attempts to prop up the struggling western empire, all point to a systemic under-militarization in the east that forced Constantinople to rely heavily on barbarian manpower, often with calamitous results. By the 420s, we find evidence for a gradual remilitarization taking place in the east, which set the stage for the major reforms of the 440s.

This chapter demonstrates that all of the available evidence indicates that the Notitia system was rapidly put into place in the 440s, likely in response to the invasions of Attila the Hun on the Danubian border. Although designed to face down the threat of the Huns, the system continued to operate as the collapse of Attila’s kingdom put increasing pressure on the eastern empire, in particular in the form of Theoderic Strabo and Theoderic the Amal, two Gothic warlords who repeatedly ravaged the Balkans and assaulted Constantinople during this period. Placed in its proper context, many central features of the Notitia system become intelligible, in particular its strong Balkan focus and the function of the praesental armies, which were used as reserve forces.

The Roman emperor ruled one of the largest empires in world history. It consisted of different peoples living in wildly different contexts. They had different expectations of who the emperor was and how he should behave, although the range of those expectations was limited. Views of emperorship were locally dependent. The image of the emperor was not the same throughout the empire, and was often closely bound to his visibility in and his relationship with a specific region. How emperors were represented through statues, historical reliefs, triumphal arches, temples and other monuments, and through the ceremonies that surrounded emperorship, had an enormous impact on how the people who encountered these monuments or participated in these ceremonies perceived their emperors. As the number of monuments accumulated over time, they created an increasingly stable local ‘memoryscape’. Existing imagery influenced both the creation of new local images and the expectations of imperial behaviour.

The Sultanate drew upon concepts of martial skill, valor and aggression attributed to the Mongol Imperium and its unprecedented conquests. While idealizing these traits, Mamluk Sultans exploited them to thwart Mongol expansion into their territories. They welcomed renegades from Mongol armies (Wafidiyya) to mimic their prowess while limiting their aggression. Mamluk cadets were imported initially from the Qipjaq Steppe in Central Asia, subsequently from Circassia in the Caucasus, with numerous other regions represented. They were instructed in Arabic, Turkish and Islam prior to being trained in arms. The Mamluk military hierarchy consisted of elite Mamluks imported as cadets in the Sultan’s service, Mamluks of senior officers, soldiers of former rulers restive over their loss of status, and descendants of 1st-generation Mamluks who served as infantry and assimilated into Arabic civil society (awlad al-nas). Advancement through the military hierarchy was marked by endemic factional rivalry in which conspiracy was expected not repudiated. Whether conspiracy enhanced the Sultanate’s military prowess or destabilized its governance remains a debated issue.

The status of Rome vis-à-vis the Roman empire is analyzed. Fears that it might be replaced and the imperial capital would be transferred are reported from the first century BC onward. Foundation myths suggested that Rome originated in the East, in Troy, and it was suspected that the capital might move back to the East. These suspicions did not materialize for centuries but became reality under Constantine with the refoundation of Byzantium as Constantinople. The choice of Constantinople as (eastern) capital may not have been a matter of course from the start. Other cities seem to have been considered first, and it is not certain why it was chosen. Furthermore, there is no contemporary evidence that Constantine always conceived his new foundation as the eastern capital of the empire, or that he intended that it should replace Rome. Claims, made first by Christian authors, that Constantine’s city was conceived from the start as the new or second Rome and also as a purely Christian city cannot be confirmed. The city actually took time to develop into an imperial capital. The city became the undisputed centre of the late Roman empire only in the reign of Theodosius I.

This chapter is mainly concerned with the political ideology, norms and behaviour associated with the Byzantine monarchy. It focuses on how the ceremonial and hierarchies of power played out in Constantinople, assessing contemporary expectations of the role and conduct of the emperor. Such expectations were often revealed most clearly in time of instability, as contemporary accounts of coups indicate. The chapter outlines the ceremonial life of the court and discusses the sacred and secular topography of Constantinople as the stage for the continuous display of elite power. The visual and non-verbal qualities to Byzantine ceremonial culture are stressed, as is the centrality of law to imperial authority, political office and spatial organisation. The principal imperial hierarchies of power (military, civil and clerical) and the relationship of the emperor and patriarch are explored, with women and eunuchs seen as integral to the workings of official hierarchies. Alternative concepts of power began to emerge in the later period, when the empire’s territorial integrity was eroding, yet the long-term resilience of traditional ideology, ceremonies and hierarchies is noteworthy.

The earliest preserved painted icons in the Adriatic date from the thirteenth century.In fact, apart from Rome, the entire Latin West seems to have embraced icons simultaneously overnight as soon as they started coming in great numbers from Byzantium following the capture of Constantinople by the crusaders in 1204. This chapter argues that the Adriatic was particularly responsive to these painted icons because it had already embraced Byzantine relief icons in the eleventh century. The examination includes both the material and written evidence for the existence of icons in the eleventh-century Adriatic, such as the extant marble Hodegetria icon from Trani and the recorded commission of a gilt silver icon for Siponto Cathedral in 1069. When it comes to Dalmatia, this investigation looks into a donation document recording five icons, one of which was made of silver, in a church built and furnished by a Croatian dignitary in the 1040s. The analysis demonstrates that by the thirteenth century, the Adriatic was conditioned by relief icons to embrace easily portable painted icons reaching its shores after the fall of Constantinople and that this area as a whole experienced a strong prestige bias towards Byzantine artefacts.
