This expanded second edition of Tilly’s widely acclaimed 2004 book brings this analytical history of social movements fully up to date. Tilly and Wood cover such recent topics as immigrants’ rights, new media technologies, new mobilizations against the Iraq War, and the role of bloggers and Facebook in social movement activities. Coverage of these and other recent events serve to expand further the book’s seminal theorizing and conceptualization of how social movements grew from eighteenth-century Europe to eventually fuel popular movements all over the world.
