While populist radical right (PRR) parties once used to shun one another internationally, this has changed over the past decade. Although the most visible forms of PRR international cooperation have occurred at European Parliament level, and/or between senior party leaders, there have also been repeated efforts by PRR youth wing elites across Europe and beyond to establish lasting links. However, beyond occasional media reports, we know very little about which youth wings cooperate, what it entails, and why it happens. Based on interviews with leading members from PRR youth wings in 10 countries between 2014 and 2022, this paper therefore asks: What are the origins, drivers, and features of PRR youth wing cooperation in Europe?
