Political Theory and Global History in Dialogue” commences an interdisciplinary dialogue on the central question—what is anticolonial solidarity? It is important to pose this question now, when appeals to “solidarity” proliferate among politicians and public health officials seeking to legitimate otherwise unpopular mobility restrictions. Their picture of solidarity in elite frameworks of nationalist-communitarianism or liberal-internationalism, however, contrasts sharply with ways of seeing solidarity typical of transnational anticolonial movements. Engaged citizens and activists continue to contest local injustices rooted in global structures of European colonialism and the legacies of informal imperialism: from the so-called Mediterranean “refugee crisis” to state-corporate invasion of indigenous territory at Standing Rock or Unist’o’ten. From this perspective, the rhetorical performance of a “crisis of solidarity” occludes the vibrant history and present of more radical, transformative practices of anticolonial solidarity. We thus propose to approach our question by thinking about both solidarity and anticolonialism together, as well as reflecting on the importance of histories of freedom, oppression, and resistance in the formation of contemporary solidarities.
