While radical right parties championing anti-immigrant platforms have made electoral gains throughout Europe, anti-immigrant sentiment—a key indicator of radical right support—has not dramatically increased during this same period. In this article, we seek to help make sense of this paradox by incorporating a contextual factor missing from previous studies: levels of anti-immigrant violence. Our key argument is that higher levels of collective violence targeting immigrants raise the salience of the immigrant/native boundary, which activates both positive and negative views of immigrants and makes these attitudes more cognitively accessible and politically relevant. This argument implies that exposure to violence against immigrants should strengthen existing prejudice (or empathy) toward immigrants and engender feelings of affinity (or antipathy) for radical right parties. Analyses of the German portion of the European Social Survey (ESS 2014 − 2019) and the Anti-Refugee Violence in Germany (ARVIG 2014 − 2017) datasets reveal a powerful interaction effect: exposure to higher levels of collective violence increased the probability of feeling closest to radical right parties among those who held neutral, negative, and extremely negative views of immigrants. However, these events were not associated with radical right sympathies among those holding pro-immigrant attitudes. We conclude that when violence against immigrants resonates with public opinion on immigrants, it opens new political opportunities for radical right parties. These findings should inform future research on the politicization of international migration, especially studies investigating how anti-immigrant attitudes translate into political outcomes.
