Social movements play a vital and increasingly visible role in modern politics.  Headline-grabbing demonstrations against authoritarian governments, police brutality, economic inequality, and other grievances suggest that, around the world, social movements are seen as powerful catalysts of change. In democracies as well as autocracies, rich countries as well as poor, citizens turn repeatedly to protest as a way of addressing a range of perceived social ills. In this engaging and accessible book, Devashree Gupta offers a thorough introduction to the study of social movements in these diverse settings, examining their structures and operations to identify the ways in which political and social contexts shape how movements behave and what impacts they have.  Drawing on multiple theoretical approaches and contemporary case studies, Gupta explores how movements think and act strategically, learning from past interactions with authorities and the experiences of other movements, to find innovative ways to challenge the status quo.  With suggestions for further reading and questions for class discussion throughout,  Protest Politics Today  will be essential reading for students of social movements and contentious politics across the world.
