This handbook provides a methodical, comprehensive, and unifying overview of the vibrant yet disparate scholarship on populism and foreign policy. By mapping the debates and existing findings, as well as presenting the different conceptual and theoretical lenses, the handbook provides new insights as to how, whether, and to what extent, populism influences foreign policy. Carefully selected international contributors connect their own work to others to offer a thorough, theoretically informed, and empirically tested academic treatment of the topic across a number of cases where populist actors are, or have been, in power. Divided into four parts (Concepts and Theories; Factors and Processes; Actors and Structures; Issues and Policy Areas), the diverse and comprehensive insights on the global, cross-regional, and transnational dimensions of populism will be of interest to scholars and students of international relations, political science, public policy, foreign policy, political theory, populism, and area studies. This text will also be of interest to those working from the perspectives of Sociology, Law, and History, as well as to the practitioners of international politics.
