This thesis explores the relationship between the Swedish autonomous left and the terrace culture of European football. It has its geographic starting point in Stockholm, Sweden and follows the three larges tStock­holm football clubs, AIK, Djurgården and Hammarby, and its supporters. The author has followed the football club Hammarby from the terrace for the entire 2011 football season, and has interviewed six political activists who visit, or used to visit, the terrace. The research context this study is incorporated into centres around the history of, and relationship between, the terrace cultures of AIK, Djurgården and Hammarby. Previous research has also focused on the radical potential of Ultras terrace culture (which is derived from Italian supporter culture) and the terrace culture from an intersectional perspective. Part of the aim of the thesis is to explore anarchist theory within an academic framework, something which has rarely been done before. The other main theoretical approach is largely based on the ideas of political theorist Chantal Mouffe and her exploration of the political identity formation of the subject in opposition to the deindividuating effect the mass can have on the individual. The method of the thesis is based on anarchist theories of participatory methods and on walking interviews developed by, among others, geographer Jon Anderson. What the research shows is that the presence of fascist values is much stronger on the terraces ofStockholmthan expected, and that the terrace culture as a whole has adopted a seemingly “apolitical” stance to try and submerge these. The participants’ stories centre on the inability to “loose oneself” in the mass of the terrace, and the feelings this inability awakens. This is the first thesis about the Ultras culture written in a Nordic context.
