Academic evaluations of the relationship between religion, secularization, and far-right collective actors have grown increasingly complicated. New religious immigrants, seen as invaders importing contradictory values imposed on the populous by EU elites, may threaten Christian and irreligious Europeans. Europe has been secularizing for decades, concurrent with a resurgence in far-right collective action, but this far-right resurgence has also accompanied an increase in religious discourse in politics. In this study, I investigate the relationship between religion, secularization, and far-right collective action utilizing three case studies. I find, with some caveats, that in Hungary, Fidesz motivates Christian voters with religious nationalist appeals, while assertive secularization motivates irreligious voters in the Netherlands. Italy is more complex, where far-right collective actors are less able to monopolize social issues. These findings speak to the critical role religious values and institutions play in shaping voter preferences and present competing options for secularist politics moving forward.
