Positioned at the crossroads of global and military history, this volume makes a major contribution to the cultural and social history of war and its aftermath. Bruno Cabanes and Cameron Givens bring together a team of leading experts to reassess the two world wars, connecting time periods, topics, and spaces traditionally treated in isolation. They examine how these armed conflicts engendered new confrontations and encounters; forged and severed transnational networks and pathways; propelled people, ideas, knowledge, and practices across and within political boundaries; and triggered complex and contested memory-making. By rethinking the relationship between military and global history, the authors encourage readers to consider the broader impact of war on twentieth-century history, from international law and humanitarianism, to race and the environment. This ambitious reframing showcases the most innovative efforts to globalize the history of the world wars and provides fertile ground for future research.
