Despite the avowed importance of religious freedom, significant debate arises over its desirability and priority in practice. One area where debate is especially fierce, and consequential for the world is violent religious extremism. The enormous political changes associated with the Arab Spring have made this debate even more relevant in recent years. The Religious Freedom Project designed this sourcebook to assist scholars, students, media, policy experts, and other interested parties in exploring the complex relationship between religious freedom and violent religious extremism. The case studies are accompanied by a select annotated bibliography of scholarly works, a listing of useful data sets, suggestions for further reading, and a bibliography of sources cited.
