This article argues that the current opposition to globalization is not a structural side effect of economic integration. Instead of assuming that globalization generates resistance, it stresses the political and interpretive processes that shape collective action. It substantiates this claim by studying the rise of an antiglobalization social movement organization called ATTAC in France. It holds that ATTAC's emergence is the product of political entrepreneurs whose actions were constrained by the ideational and organizational legacies of previous contentious episodes, particularly the December 1995 strikes. Finally, it contends that ATTAC's success stems in part from its ability to produce a hybrid discourse that marries state interventionism with participatory politics.
