This article explores the intersections between classic anarchist praxis and contemporary anti-corporate globalization activism in Barcelona. It engages in a sympathetic debate with two key literatures, pushing my argument in contrasting, yet ultimately related directions. I differ with accounts that emphasize an identity, arguing instead that anti-corporate globalizationmovements involve a confluence between anarchist principles and emerging networking logics associated with late capitalism. Given this affinity, anarchism is one among several related positions radicals adopt in particular contexts. Indeed, radical identities reflect a growing emphasis on multiplicity, openness, andflexibility. Attention to such specificities is important for analytical and strategic reasons.
