In Piracy and the Origins of Universal Jurisdiction, Mark Chadwick relates a colourful account of how and why piracy on the high seas came to be considered an international crime subject to the principle of universal jurisdiction, prosecutable by any State in any circumstances. Merging domestic and international law international and domestic, history, literature and sociology, the author weaves an intricate tale that reveals the pirate to be the original “enemy of mankind” and forerunner of today’s international criminals: those who commit genocide, crimes against humanity and war crimes. In so doing, Mark Chadwick proposes a convincing reappraisal of the pirate’s role in the crystallisation of international criminal law, bringing much-needed clarity to a disputed area of international legal history.
