This book seeks to launch a new research agenda for the historiography of Dutch foreign relations during the nineteenth and twentieth centuries. It does so in two important ways. First, it broadens the analytical perspective to include a variety of non-state actors beyond politicians and diplomats. Second, it focuses on the transnational connections that shaped the foreign relations of the Netherlands, emphasizing the effects of (post-) colonialism and internationalism. Furthermore, this essay collection highlights not only the key roles played by Dutch actors on the international scene, but also serves as an important point of comparison for the activities of their counterparts in other small states.
