Can there ever be trust between states? This study explores the concept of trust across different and sometimes antagonistic genres of international political thought during the seventeenth century. The natural law and reason of state traditions worked on different assumptions, but they mutually influenced each other. How have these traditions influenced the different concepts and discussions of trust-building? Bringing together international political thought and international law, Schröder analyses to what extent trust can be seen as one of the foundational concepts in the theorising of interstate relations in this decisive period. Despite the ongoing search for conditions of trust between states, we are still faced with the same structural problems. This study is therefore of interest not only to specialists and students of the early modern period, but also to everyone thinking about ways of overcoming conflicts which are aggravated by a lack of mutual trust.

The Thirty Years’ War (1618-1648) remains a puzzling and complex subject for students and scholars alike. This is hardly surprising since it is often contested among historians whether it is actually appropriate to speak of a single war or a series of conflicts. Similarly emphasis is also put on the different motives for going to war, as conflicting religious and political interests were involved. This research companion brings together leading scholars in the field to synthesize the range of existing research on the war, which is still fragmented and divided along national historical lines, and to further explore the complexities of the conflict using an innovative comparative approach. The companion is designed to provide scholars and graduate students with a comprehensive and authoritative overview of research on one of the most destructive conflicts in European history.

One of the great paradoxes of post-medieval Europe, is why instead of bringing peace to a disorganised and violent world, modernity instead produced a seemingly endless string of conflicts and social upheavals. Why was it that the foundation and institutionalisation of secured peace and the rule of law seemed to go hand-in-hand with the proliferation of war and the violation of individual and collective rights? In order to try to better understand such profound questions, this volume explores the history and theories of political thought of international relations in the seventeenth century, a period in which many of the defining features and boundaries of modern Europe where fixed and codified. With the discovery of the New World, and the fundamental impact of the Reformation, the complexity of international relations increased considerably. Reactions to these upheavals resulted in a range of responses intended to address the contradictions and conflicts of the anarchical society of states. Alongside the emergence of "modern" international law, the equation of international relations with the state of nature, and the development of the "balance of power", diplomatic procedures and commercial customs arose which shaped the emerging (and current) international system of states. Employing a multidisciplinary approach to address these issues, this volume brings together political scientists, philosophers, historians of political thought, jurists and scholars of international relations. What emerges is a certain tension between the different strands of research which allows for a fruitful new synthesis. In this respect the assembled essays in this volume offer a sophisticated and fresh account of the interactions of law, conflict and the nation state in an early-modern European context.
