Introduction

The Byzantine Empire is the term which scholars have used since the sixteenth century to refer to the eastern Roman Empire from around the fourth century AD. Following the transfer of the Roman capital from Rome to Constantinople (on the site of the ancient city of Byzantium) by Constantine I (r. 306-337) in 330, the eastern Roman, or Byzantine, Empire gradually developed administrative, cultural and political qualities which distinguished it from the classical Roman Empire of the early centuries AD. As the western Roman Empire disintegrated from the fifth century onwards Byzantium became the state which preserved continuity with the imperial legacy, including legal and governmental norms and literary traditions. The official conversion of the Roman world to Christianity in the fourth century, the encounter of Byzantium with Islam, beginning in the seventh century and continuing thereafter, the temporary conquest of the Empire by Latin crusaders between 1204 and 1261, and its increasing shift towards a Greek-speaking, Anatolian society all made this a very different sort of Roman Empire to that of Augustus, or even Domitian. Nevertheless, it remained in its own self-conception the Roman Empire until its final fall to the Ottoman emperor Mehmet II (r. 1451-1481) in 1453, when a state which had dominated the entire eastern Mediterranean consisted of little more than its capital and a few strongholds around the Aegean.

The coinage of the Byzantine Empire reflects these dramatic changes of culture and fortune. Constantine I stabilised the Roman precious-metal coinage, which had suffered in the third century, by creating the solidus – a high-purity, 4.5g. gold coin described by R. S. Lopez in 1951 as the ‘dollar of the Middle Ages’. This was accompanied in 498 by a  series of copper denominations, clearly marked with their values, created by the coinage reform of Anastasius I (r. 491-518). Silver came to be used only sporadically in this system, which, with an increasingly reduced range of copper denominations, served the empire until the eleventh century. Debasement of the gold coinage, however, had begun in the ninth century and become noticeable from the tenth, weakening the Byzantine monetary economy considerably. A series of reforms by Alexios I Komnenos (r. 1081-1118) again stabilised the system, though around a gold denomination of lower purity than the solidus had been – the new hyperperon. From the eleventh century, though, reduced imperial territory and the growing involvement of various western powers in the eastern Mediterranean, including the Italian city states of Venice, Genoa and Pisa, put the Byzantine currency in the position of international competitor, rather than superior arbitrator of value.

Following Latin rule of the empire from 1204-1261, the Greek emperors who recovered Constantinople continued to mint in the tradition established by Alexios I, but from an ever-weaker economic position, ultimately resulting in the abandonment of gold minting completely, increased use of foreign currency in state dealings and reduced output of copper coinage. From changing religious imagery, to debasement and reform, to concave coins and the reasons for their existence, Byzantine monetary history is visually compelling and intimately linked to the successes and difficulties of its issuing state. With continuous state minting over a period of over 1000 years, extensive scholarly research and some very well-published collections, coinage has been crucial to the telling of the stories of the Byzantine Empire and remains at the heart of current scholarship.

The Aksumite Empire was, for a while, a contemporary of Byzantium, and owing to the close diplomatic ties between the two states and the visual similarity of their coins, as well as arguments by some scholars for a close economic relationship, Aksumite and Byzantine numismatics have often been considered in parallel. The Aksumite Empire dominated the regions of modern Ethiopia and Eritrea from roughly the late third century AD to the seventh century AD, though cultural and political continuities tie it to earlier developments and the later society of medieval Ethiopia.

Aksum was a wealthy inland city, which dominated a territory stretching at times across the Red Sea to dominate southern Arabia, and which frequently launched military raids to the south and west of its core territories. Known primarily from foreign (Roman/Byzantine) accounts and archaeological excavation, the Aksumite Empire seems to have been wealthy, militarily successful and, in places, quite urbanised. Burials in Aksum testify to the wealth it enjoyed as a result of its access to western Indian Ocean trade routes, as do finds of Aksumite coins in south India. Aksum was also an officially Christian state from the early decades of the fourth century – a fact proclaimed on its coinage as well as by the cessation of commemorating kings with the erection of huge monolithic stele. Its Christianity was one of the factors which linked it to Byzantium, though the two states adhered to different views of the relationship between Christ and the other members of the holy Trinity.

With relatively little narrative source material, in comparison to the Byzantine Empire, and archaeological excavation coming to the fore only in recent decades, coinage has been crucial to exploring and publicising the history of this remarkable Late Antique empire. Many Aksumite rulers, and their sequence, are only known numismatically and changes in state religion and military activity can be discerned from, respectively, coin iconography and coin distribution. The obvious complexity of the Aksumite monetary system, involving regular minting in gold, silver and copper-alloy, as well as the unique practice of gilding specific areas of both silver and copper-alloy denominations, and  a growing capacity to connect archaeological and coin evidence ensures that many more questions will continue to be asked, and answers proposed, in the research of Aksumite numismatics.
