During the 1980s, a number of new protest movements emerged that protested against the welfare state and right-wing politics. Influenced by punk, anarchism and the libertarian left, activists often met in so-called autonomous social centers. In many European countries, resistance became contentious, but resistance also took the form of everyday practices. The aim of this article is to study political resistance in the 1980s Sweden, carried out by the cultural association Ultra between 1980 and 1988. Based on theories of everyday resistance, contentious politics and prefigurative politics, ideas, and practices in Ultrahuset (the Ultra house) are examined. I study how the everyday resistance developed toward a more contentious resistance, as the relationship with the local authorities changed, and how the concept of prefigurative politics contributes to an understanding of the relationship between everyday practices and resistance. Source material consists of texts and illustrations produced in Ultrahuset, media material and interviews with former members. The result show that the activism in Ultrahuset can be understood as a way of doing prefigurative politics through everyday resistance, but also that during the 1980s, when the relation between Ultra and the surrounding society changed, the resistance also changed, becoming more outward-looking and contentious.
