This book analyzes the individual and contextual determinants of protest politics in Western Europe. Building on different theoretical perspectives, from social movements theory to political behavior approaches, the author provides new empirical evidence on the patterns of protest politics. Readers will discover why some citizens are more likely to get involved in protests than others, and why levels of protest differ from country to country. The author illustrates that engagement in political protest is often rooted in the interplay of the protester's individual characteristics and their home country's contextual characteristics.
