Economic Warfare and the Sea examines the relationship between trade, maritime warfare, and strategic thought between the early modern period and the late-twentieth century. Featuring contributions from renown historians and rising scholars, this volume forwards an international perspective upon the intersection of maritime history, strategy, and diplomacy. Core themes include the role of 'economic warfare' in maritime strategic thought, prevalence of economic competition below the threshold of open conflict, and the role non-state actors have played in the prosecution of economic warfare. Using unique material from 18 different archives across six countries, this volume explores critical moments in the development of economic warfare, naval technology, and international law, including the Anglo-Dutch Wars, the French Revolutionary and Napoleonic Wars, the First World War, and the Second World War. Distinct chapters also analyse the role of economic warfare in theories of maritime strategy, and what the future holds for the changing role of navies in the floating global economy of the twenty-first century.
