This special issue presents a range of case studies that exemplify the potential of kinship for thinking about and acting in relation to various kin and non-kin others in ways that invite us to reconsider the boundaries of politics and the political. The introduction examines ethnographic research that informs the articles in the special issue and shows the ways in which tensions and continuities across relations of intimacy, family and kinship, play out in response to contemporary capitalism. The articles in the special issue demonstrate the usefulness of exploring the interface and overlaps between the political and other fields that are all too often positioned – within scholarship and public discourses – as the antithesis of the political, variously understood in terms of the private, the familial, the domestic and the sphere of kinship.
