ABSTRACT When migrants and displaced people make claims about their rights to be political and become acting political subjects, they challenge conventional notions of political and political communities. Drawing on ethnographic fieldwork conducted in Prague with Ukrainian citizens displaced by the 2022 Russian invasion, this article brings into conversation critical citizenship studies and literature on solidarity with refugees to explore the political acts of displaced Ukrainians and the solidarity practices of local activists. By doing so, the article focuses on the intricate transformations that (re)shape politics in terms of new subjectivities and social relations. When displaced people from Ukraine disrupted presumptions about their political invisibility and formed synergetic solidarity relations with local activists, their actions made new ways of relating and caring possible. This further transformed their political subjectivities from claimants of rights to Czech society (and its institutions) to claimants of rights within Czech society.
