What do Beppe Grillo, Silvio Berlusconi, Emmanuel Macron (and also Donald Trump) have in common? They are prime examples of the personalization of politics and the decline of political parties.

This volume systematically examines these two prominent developments in contemporary democratic politics and the relationship between them. It presents a cross-national comparative comparison that covers around 50 years in 26 democracies through the use of more than 20 indicators. It offers the most comprehensive comparative cross-national estimation of the variance in the levels and patterns of party change and political personalization among countries to date, using existing works as well injecting fresh cross-national comparative data. In the case of party change, it offers an analysis that extends beyond the dichotomous debate of party decline versus party adaptation. In the matter of political personalization, the emphasis on variance helps in bridging between the high theoretical expectations and disappointing empirical findings. As for the theoretically sound linkage between the two phenomena, not only is this the first study to comprise a comprehensive cross-national examination, but it also proposes a more nuanced understanding of this relationship.
