Theories that offer a historicized account of international relations often consider the late middle ages as a period of fundamental change. Territorial political units, geographically defined borders, and distinctions between internal and external gradually developed and became increasingly important. As a result international relations were not only governed by competition between individual lords, by feudal networks, or by imperial and papal univers- alism, but also by the agency of newly developing geopolitical units, such as kingdoms, territories, towns, and local lordships. On the basis of the Guelders War of Succession (1371- 1379) this paper offers a snapshot of this process of transition, demonstrating the dense and composite nature of international relations during the fourteenth century in the western part of the Holy Roman Empire.
