This edited volume offers a fresh look into the history of the League of Nations. It uses the League of Nations' involvement in social issues as a unique prism for understanding the League's development, as well as the development of interwar international relations more generally. Off the beaten path of diplomatic history, this perspective allows the authors to trace less familiar actors and unexpected alliances. It enables contributors to reassess the League's impact on European societies, their colonial possessions, and non-European states. As such, it also marks a paradigm shift in the League's Eurocentric historiography toward one that acknowledges its global reach
