The relation between different forms of oppressive structures has been an object of dispute throughout the history of feminism. One of the most influential debates devoted to this issue is the one between Judith Butler and Nancy Fraser during the 1990s. Although the debate attracted a great deal of attention, and both thinkers have subsequently developed their theories by introducing novel concepts to describe oppression as well as the conditions of contemporary emancipatory movements, they have not continued to engage in each other's work. This article offers a critical reading of the positions that Fraser and Butler took in the 1990s debate, as well as an identification of shifts in their thinking ensuing from the debate. A particular interest of the article is their conceptualisations of the grounds for political alliances among groups with distinct experiences of oppression. The article not only offers a critique of both Butler's and Fraser's positions in the 1990s debate but also argues that the way in which Fraser's trajectory has come to directly address the issue of the capitalist social order, and which can also be read as an implicit self-critique, is more satisfactory than Butler's later work on precarity. © The Author(s) 2023.
