Westerners invented social movements during the 18th century, but after that social movements became vehicles of popular politics across the world. By locating social movements in history, prize-winning social scientist Charles Tilly provides rich and often surprising insights into the origins of contemporary social movement practices, relations of social movements to democratization, and likely futures for social movements. Shows how social movements are changing, including the impact of new technologies and globalization. Traces the invention and evolution of social movements with lessons for how social movements could lose their vigor. Explores fundamental questions such as 'How does democratization really occur?' Considers the relation of movements to identity, citizenship, and capital and questions whether social movements are viable in authoritarian states. Students will appreciate Tilly's vivid examples from around the world (including a fantasy of 17th century figures John Wilkes and Samuel Adams trying to discern the effectiveness of 2003 Iraq War demonstrators).
