Full edition for scientific use. What impact do populist and radical-right ideas have on a country’s foreign policy? Although research on the nexus of populism and foreign policy has taught us much about populists’ conduct of foreign affairs, we still lack distinctive categories characterising the nature of a populist and radical-right foreign policy. Furthermore, the impact of populist and radical-right parties and their ideas on foreign policy as well as the question of how to measure this impact are still unanswered. This article seeks to address this research gap by examining the populist and radical-right Freedom Party’s participation in the Austrian government from 2017 to 2019, and applying qualitative content analysis to government programmes as well as quantitative text analysis to official press releases. Overall, the article makes three contributions to the literature. First, it proposes distinctive characteristics of a PRR foreign policy conception. Second, it introduces an approach to measure the impact of this conception on a country’s foreign policy. And finally, it determines this impact on Austria’s foreign policy.
