Populist Foreign Policy: Mapping the Developing Research Program on Populism in International Relations

This article reviews one of the expanding research programs in international relations (IR): the study of populist foreign policy (PFP). Recent years have witnessed a significant proliferation of IR scholars researching the nexus between the global rise of populism and their foreign policies across different countries, regions, and sub-fields. However, scientific progress at such stage of this research program demands an in-depth “mapping” of its different ontological approaches. To this end, we identify and explore five “schools” of PFP that have been consolidated in the last decade, while highlighting their accomplishments in understanding the distinctive populist elements in foreign policy and their possibilities of analyzing local and external conditions under which PFP impacts global politics. We also set the stage for future contributions on the drivers, patterns, and effects of PFP, under the assumption that the populist phenomenon and its transnational dimensions will continue to affect IR prospects for a long time to come.
