This chapter explores how citizenship, nationalism and gender intersect, specifically in deeply divided transitional societies. It discusses how these intersections impact women’s political citizenship and public participation with the aim of defining what a gender-just political citizenship entails. This chapter thus provides a theoretical framework that addresses gendered political citizenship in ethno-nationalist societies and explores how gender equality is affected by transitions from war to peace; how this can open space for renegotiating citizenship but also cause a backlash for women’s rights. The theories of agonistic peace and transversal politics are studied, especially in terms of their potential for creating space for inclusive dialogue and political activism in deeply divided societies. This chapter then theorises how women’s grassroots cross-community activities could inform the conceptualisation of citizenship so that it recognises, validates and encourages women’s political participation. Transversalism is utilised to imagine a gender-just citizenship that builds on intersectionality, multi-sited participation and facilitates coalitions across difference.
