The Roman Imperial Court in the Principate and Late Antiquity examines the Roman imperial court as a social and political institution in both the Principate and Late Antiquity. By analysing these two periods, which are usually treated separately in studies of the Roman court, it considers continuities, changes, and connections in the six hundred years between the reigns of Augustus and Justinian.Thirteen case studies are presented. Some take a thematic approach, analysing specific aspects such as the appointment of jurists, the role of guard units, or stories told about the court, over several centuries. Others concentrate on specific periods, individuals, or office holders, like the role of women and generals in the fifth century AD, while paying attention to their wider historical significance. The volume concludes with a chapter placing the evolution of the Roman imperial court in comparative perspective using insights from scholarship on other Eurasian monarchical courts. It shows that the long-term transformation of the Roman imperial court did not follow a straightforward and linear course, but came about as the result of negotiation, experimentation, and adaptation.
