"From the Occupy protests to climate change school strikes and the Black Lives Matter movement, the 21st century has been rife with activism. Although very different from one another, each of these movements have created alliances across borders and show that these issues are not confined to individual nation states. In this book, Daniel Laqua shows that these global efforts are not just a recent phenomenon, and that as long as there have been borders, activists have sought to cross them. Showing how individuals, groups and organisations have fostered bonds in their quest for political and social change, and exploring how national or ideological boundaries have impacted their efforts, Activism without Borders traces activists and movements from 1870 to the 21st century. Focusing on Europe but with a global outlook, it examines groups and individuals that expressed far-reaching ambitions and operated within imperial or post-colonial settings. From feminism and socialism to anti-war campaigns and green politics, this book offers a synthesis of transnational activism through four analytical lenses; connectedness, ambivalence, transience and marginality. In doing so, it demonstrates the intertwined nature of different movements, problematizes transnational action, discusses the temporary nature of some alliances, and shows how transnationalism has been used by those marginalised at the national level. With a broad chronological perspective and thematic chapters, it provides historical context, clarifies terms and concepts and offers an alternative history of the modern world through the lens of activists, movements and campaigns."--
