Existing research has shown that there is considerable diversity when it comes to populist radical right party (PRRP) organization, but it is unclear why this is the case. The Netherlands provides an ideal laboratory to examine this question. Within two decades, the country witnessed the rise of several PRRPs, including the List Pim Fortuyn (LPF), the Party for Freedom (PVV) and Forum for Democracy (FvD). Despite ideological similarities, there are clear differences between these parties in terms of party organization. We argue that the organizational model of the FvD is a synthesis of the LPF and the PVV. To avoid internal dissension that brought about the demise of the LPF, the FvD adopted organizational elements of Geert Wilders’s ‘personal party’. The FvD also drew lessons from the financial limitations of the PVV by creating a large membership base. The findings show clear evidence of institutional learning. By learning from the experiences of others, PRRPs are becoming much better equipped to endure setbacks, which suggests that they are less likely to subside in the near future.
