Book excerpt: The aim of this book is to highlight and begin to give 'voice' to some of the notable 'silences' evident in recent years in the study of contentious politics. The seven co-authors take up seven specific topics in the volume: the relationship between emotions and contention; temporality in the study of contention; the spatial dimensions of contention; leadership in contention; the role of threat in contention; religion and contention; and contention in the context of demographic and life-course processes. The seven spent three years involved in an ongoing project designed to take stock, and attempt a partial synthesis, of various literatures that have grown up around the study of non-routine or contentious politics. As such, it is likely to be viewed as a groundbreaking volume that not only undermines conventional disciplinary understanding of contentious politics, but also lays out a number of provocative new research agendas.
