This book examines and analyses the ongoing transformation of Political Islam Movements (PIMs) in seven countries where the Arab uprisings phenomenon took different forms: massive mobilization that induced leadership change (Tunisia and Egypt), limited demonstrations with a reformist agenda (Morocco, Jordan, and Kuwait), and a bloody civil war (Syria and Yemen). The idea behind this research design was to understand how PIMs acted and reacted in response to the different challenges and opportunities created by the Arab uprisings in different contexts.
