This paper explores the ways nationalism has been theorised in classical and contemporary sociology. More specifically, the author analyses the relevance of Randall Collins’s contribution to theories of nationalism. Since Collins’s work is firmly rooted in the classical tradition, including the reinterpretation and synthesis of Weber, Durkheim and Goffman, the first part of this paper zooms in on the classics of sociology and their treatment of nations and nationalism. The second part of the paper outlines the key features of Collins’s (...) approach and identifies the strengths and weaknesses of this position. The final part builds on the footsteps of Collins and others to articulate an alternative approach focused on the coercive organisational, ideological and micro-interactional grounding of nationalisms.
