'Nothing about us without us': organizing disabled people's solidarity within and beyond borders in a polarized age.

This article examines collective action and the alliances between social movement organizations engaged in the work of solidarity with disabled people within and across borders during austerity. Building upon social movement theory, specifically political opportunities and resource mobilisation, we focus our analysis on data from in-depth interviews with thirty-five organizations at the UK and European levels, where we examine both how solidarity is operationalized by such organizations and the everyday cooperation and alliances they build with others in a UK policy context that has been hostile to disabled people and a European context which disabled people's solidarity organizations have sought to seize as political opportunities. Our study therefore adopts a multi-level approach by analysing the building of alliances between organizations at the local, national and transnational levels and it reveals the impact of the political context and organisational pressures which can diminish resources and generate competition, thus placing strains on solidarity between disabled people.
