This book is a collection of case studies that provides fresh insights into the history of political activism in Europe's long 1970s. It covers the full spectrum of such groups, from the far left to the neofascist right, and from the various parts of Europe, including East and West. The chapters in this book push the boundaries of our knowledge with regard to transnational spaces. For many political activists at the time, identifying with a 'transnational' or 'global' protest movement provided both legitimacy for their claims and stood for the promise of sweeping change. Existing research has often reproduced such perceptions. This book goes beyond such an approach by distinguishing between different forms of transnational spaces. More specifically, it recognizes important differences between imagined spaces of solidarity and belonging, spaces of knowledge circulation and spaces of social experience and political action. Each chapter uses this new framework and analyses the interrelationship and significance of each of these three spaces. Beyond Transnationalism will be of particular interest to historians, political scientists and educators. The chapters in this book were originally published as a special issue of European Review of History.
