ABSTRACT Traditionally, a framework of demand- and supply-side factors provides insights into FRP emergence. This study proposes an alternative framework for FRP emergence by applying a more active – social movement – theory, namely the political process model. The political process model consists of three distinct dimensions that can individually affect FRP emergence. Together, they serve as necessary, but also sufficient, conditions for FRP emergence. First, political opportunities refer to dynamic factors outside the FRP that can provide a favourable (institutional) environment for emergence. Second, resource mobilisation refers to more structural factors through which people can mobilise and engage in collective action. Third, a situationally adjusted master frame includes cognitive and cultural factors that allow FRPs to attract both electoral and financial support. While the model is not without its criticisms, this study argues it provides a much-needed complement to more structural and variable-oriented theories of FRP emergence.
