The Islamist movement that has emerged from the internationalization of the Muslim Brotherhood is referred to by Florence Bergeaud-Blackler as "Frérisme." In this bestselling nonfiction book from France, the esteemed CNRS anthropologist thoroughly and objectively explores the origins of Frérisme, its doctrinal foundations, organization, and methods, as well as its recruitment and indoctrination techniques. She demonstrates how the movement extends its influence into the heart of European societies by relying on their institutions, undermining the values of human rights, or "Islamizing" knowledge.
