Abstract
<p>In this publication, the author compares four representatives of Western European right-wing populist parties (FPÖ, AfD, PVV, RN) based on their ideologies, histories, organisation, voter bases and their cooperation in Europe. He concludes that they constitute more than an unintended family. This uniquely extensive comparison considers right-wing populism the ideological core of their relation to each other. Growing reconciliation among right-wing populist parties can also be seen in their increasing willingness to cooperate within the European Parliament. However, a qualitative analysis of their party programmes, which forms the main part of this study, reveals significant differences between them, for example in terms of the parties’ economic and environmental policies.</p>
