“Money, money, and more money.” In the eyes of early modern warlords, these were the three essential prerequisites for waging war. The transnational studies presented here describe and explain how belligerent powers did indeed rely on thriving markets where military entrepreneurs provided mercenaries, weapons, money, credit, food, expertise, and other services. In a fresh and comprehensive examination of pre-national military entrepreneurship – its actors, structures and economic logic – this volume shows how readily business relationships for supplying armies in the 17th and 18th centuries crossed territorial and confessional boundaries. By outlining and explicating early modern military entrepreneurial fields of action, this new transnational perspective transcends the limits of national historical approaches to the business of war.
