In scarcely a century, Salafism has transformed Sunni Islam. Claiming to be a revival of the purest form of Islam, this movement promotes ultraconservative social and religious norms and rejects all non-Sunni reli gious groups. In Egypt, its influence has grown to the point of reshaping mainstream conceptions of the faith. How did such a deep religious transformation sweep through Egypt so rapidly? What is the significance of Salafism for the country’s political scene, both before and after Hosni Mubarak fell from power in 2011? Twilight of the Saints examines the history of Salafism in Egypt from its 1920s emergence in Cairo’s scholarly circles through the present day, shedding new light on the movement’s shifting relationship to politics. Drawing on extensive fieldwork and interviews, Stéphane Lacroix illustrates how Salafism redefined what it means to be Muslim for Egyptians. He emphasizes the factors that distinguish the Salafis from the Muslim Brotherhood, despite their parallel trajectories. Lacroix explores how Salafism influenced the dynamics of the 2011 revolution and the democratic transition that ended with the army’s takeover of the country, as well as how it has fared since. In this context, MEI will host a book talk with Stephane Lacroix to present the book and reflect on our understanding of the relationship of Salafism, politics, and authoritarianism in Egypt, and its significant implications for the wider Muslim world.
