Coalitions across Borders shows how social movements have cooperated and conflicted as they work to develop a transnational civil society in response to perceived threats of neoliberalism—free trade, privatization, structural adjustment, and unbridled corporate power. The authors explore the processes of transnational mobilization, discussing the motivations and methods of cross-border cooperation as well as the conflicts that have affected movement abilities to promote social change. The original case studies included in this volume represent a diverse cross section of transnational movement coalitions—from various regions and nations, representing different movement interests, and addressing a range of economic injustices. Coalitions across Borders reveals the many social conditions that enable and constrain the formation of transnational civil societies and the ways in which movement actors manage conflicts as they work toward common goals.
