This article interrogates the claim that a transnational anti-globalisation social movement has emerged. I draw on constructivist social movement theory, globalisation studies, feminist praxis and activist websites to make two main arguments, mapping on to the two parts of the article. First, a movement has indeed emerged, albeit in a highly contested and complex form with activists, opponents and commentators constructing competing movement identities. This article is itself complicit in such a process – and seeks to further a particular construction of the movement as a site of radical-democratic politics. Second, the movement is not anti-globalisation in any straightforward sense. Focusing their opposition on globalised neoliberalism and corporate power, activists represent their movement either as anti-capitalist or as constructing alternative kinds of globalised relationships. Threading through both my arguments is a normative plea to confront the diverse relations of power involved in both globalisation and movement construction in order that globalised solidarities be truly democratic. This is to challenge hierarchical visions of how best to construct ‘the anti-globalisation movement’
