The chapter starts with empirical teasers. The reliance on maps during the Congress of Vienna, Sanskrit poetics in premodern South Asia, the coronation in the Middle Ages, and the European Parliament’s staged plenary votes in the absence of formal competencies all find a mention. The chapter then defines representants as those practices, artefacts, and language that stand in for the units of the international system in international interactions. In comparison to existing theories of changes of international orders, a focus on representants carries some advantages. Approaches studying material capabilities omit how highly centralized orders can exist even if capabilities are widely distributed. Constructivists could do more to identify the transmission mechanisms through which abstract ideas affect practical politics. How exactly ideas are materially instantiated leaves its mark on historical events. Theoretically, the book’s aim is to anchor the macro-processes of international order’s stability and change in everyday and extraordinary embodied encounters. The focus is on scaling up (from new materialist and much of practice scholarship) and scaling down (from traditional scholarship on transformations of international order) at the same time. The chapter briefly summarizes the theory of change of international orders, and it provides an outline of the monograph.
