This paper argues that the national populisms of Northern and Western Europe form a distinctive cluster within the wider north Atlantic and pan-European populist conjuncture. They are distinctive in construing the opposition between self and other not in narrowly national but in broader civilizational terms. This partial shift from nationalism to "civilizationism" has been driven by the notion of a civilizational threat from Islam. This has given rise to an identitarian "Christianism", a secularist posture, a philosemitic stance, and an ostensibly liberal defence of gender equality, gay rights, and freedom of speech. The paper highlights the distinctiveness of this configuration by briefly comparing the national populisms of Northern and Western Europe to the Trump campaign and to the national populisms of East Central Europe. It concludes by specifying two ways in which the joining of identitarian Christianism with secularist and liberal rhetoric challenges prevailing understandings of European national populism.
