Abstract
This article expounds Samuel von Pufendorf’s evolving theory of multiple monarchy, from the publication of his early work on the form of the Holy Roman Empire, through his natural jurisprudence, to his historical accounts of European statesmanship. Although his comments on the irregularity—indeed, the monstrosity—of composite kingdoms are well known, it is less often appreciated that Pufendorf came to be able to accommodate them within a typology of constitutional systems developed against the background of his theory of the moral personality of the state. Pufendorf’s political thought after his early book on the Holy Roman Empire is the record of a consistent attempt to confront the complexities of multiple monarchy rather than capitulate in the face of them.
