This article casts new light on the processes of collective claims and identity formation in social movements, with the help of the radical political framework of Laclau and Mouffe (Hegemony and socialist strategy: towards a radical democratic politics, Verso, London, 2001). Polish tenants, classified as “losers” of transition and marginalized in the mainstream discourse, nevertheless act collectively, mobilizing alliances with other democratic struggles and thus challenge the hegemony of neoliberal dogmas in the country. The very fact of mobilization of a socially and economically deprived group demanding the right to the city is provocative in the studied context. The empirical foundations of our study are 20 in-depth semi-structured interviews conducted with Polish tenants’ activists cross-referenced with media material produced by and about the movement, and previous studies on the topic. The contribution of this article is twofold: it combines social movement theory with radical political framework and fills the empirical gap in the body of literature on social movements in post-socialist Europe.
