Revolutions, social movements, religious and ethnic conflict, nationalism and civil rights, and transnational movements: these forms of contentious politics combine in Charles Tilly's and Sidney Tarrow's Contentious Politics. The authors present a set of analytical tools and procedures for study, comparison, and explanation of these very different sorts of contention. Drawing on many historical and contemporary cases, the book shows that similar principles describe and explain a wide variety of struggles as well as many more routine forms of politics. This fully revised and updated edition explores some of the major contentious events that have taken place since the original book was published in 2007, including the Occupy movement in the United States, the campaign for free elections in the city of Hong Kong, insurrections against Middle Eastern dictatorships, and armed conflicts on the border of the former Soviet Union.
