Is the periodization of the Principate according to dynasties also valid for the history of the court? Was there continuous development of court life – such as increasing institutionalization – or were certain elements of court life linked to certain styles of rule, recurring occasionally but then disappearing again? In answering these questions, this chapter focuses on elements that are central in this book: place; composition; activity; and the institutionalization or ritualization of court life. The chapter finds that there were few neatly defined chronological developments of the court, other than changes which were directly related to the increasing absence of the emperors from Rome. There was, however, a consistent moralistic discourse, often created and perpetuated by courtiers, surrounding the emperor’s behaviour at court. This meant that the expectations of members of the Roman court could influence emperors just as they could influence life at their court.
