The volume is divided into six chapters. The introduction covers the theory of collective action in its many manifestations as well as the process of drawing out theoretical implications. The second chapter goes to the core of the mobilization issues, especially with regard to the role of leadership, which is inextricably linked to mobilization. The third chapter applies the concept of adaptation to the development of more productive tactics that promote mobilization in support of a public good and minimize the possibility of repression. In chapter four, five spatial hypotheses based on rationality and formal theories are developed and the role of time in protests is addressed. The fifth chapter focuses on the fundamental problems of terror with evidence from the Basque region of Spain and France from Ireland against the Provisional Irish Revolutionary Army in Northern Ireland. The final chapter surveys the empirical evidence and summarizes the support of collective action theory.
