This chapter explores human rights organizations resisting the illiberal reconfiguration of Polish society that has been spearheaded by the country’s ruling political party since 2015. By decreasing financial support, launching smearing campaigns, and engaging in intimidation practices, the political regime aims to influence the scope of economic, symbolic, human, and social resources available to human rights organizations. Using data from representative surveys and in-depth interviews with representatives of human rights organizations and other civil society organizations, we systematically examine opportunities and limitations in navigating such institutional pressures. Our study demonstrates that organizations’ characteristics and environmental conditions determine the action repertoire, including diversification of resources, coalition building, and public campaigns, that sustains an organization’s legitimacy and (re)generates various forms of support.
