This article examines the gender ideology of the parliamentary radical right populist party (RRPP) – the Sweden Democrats. More specifically, the article analyses how the party integrates old nationalist ideas about the importance of traditional gender roles and male superiority for the stability and welfare of the nation with new nationalist ideas about Sweden as the most gender-equal nation in the world. Prior studies suggest that RRPPs have integrated gender equality as a policy measure against multiculturalism and immigration. Our analysis shows this to be true also of the Sweden Democrats. However, unlike prior scholarship, we argue that the integration of gender equality is a tenuous and difficult one, as nationalist ideologies generally rest on ideas of sexual difference and male superiority. While the Sweden Democrats claim to support gender equality in discussions of multiculturalism and immigration, the party is a fierce critic of gender equality in all other contexts.
