Social Movements, third edition, is a core or supplemental text suitable for upper-year undergraduate social movements courses offered out of sociology, labour studies, and political science departments in both colleges and universities. It offers a concise yet comprehensive introduction to the field’s historical background and major theories. Key issues are explored in the context of specific social movements and counter-movements active within Canada and around the world, showing how these movements originate, mobilize participants, and bring about social change. Chapters on the women’s, Indigenous, LGBT, environmental, and global justice movements reveal exactly how these groups maximized their resources to attract followers and further their goals. The text also discusses the cluster of protest movements that arose in many countries in the 1960s and how the strategies and changes implemented then continue to influence collective action in the twenty-first century. The third edition is enhanced with photographs to help students visualize various social movements and includes content on recent movements such as the Arab Spring, Idle No More, the Quebec student movement, and Occupy.
