The Handbook presents a most updated and comprehensive exploration of social movement research. It not only maps, but also expands the field of social movement studies, taking stock of recent developments in cognate areas of studies, within and beyond sociology and political science. While structured around traditional social movement concepts, each section combines the mapping of the state of the art with attempts to broaden our knowledge of social movements beyond classic theoretical agendas, and to identify the contribution that social movement studies can give to other fields of knowledge.
