Far too little academic attention has been paid to more contemporary forms of transnational anti-fascist militancy. Yet this study supports the idea that this field of anti-fascist activity has remained important. This article examines transnational anti-fascist militancy in the 1990s through a case study of Britain's Anti-Fascist Action (AFA). In doing so it offers an in-depth account of AFA's attempts to establish an international militant anti-fascist network in conjunction with Germany's Autonome Antifa (M). The article identifies the common interests, challenges and limitations of this network. The final part of his article reflects on the cross-border importation of AFA to the Irish Republic.
