First published in 1969 as part of a series edited by renowned Islamic scholar Albert Hourani, this book has been the standard source for the history of the revivalist Egyptian movement—the Muslim Brethren up to the time of Nasser. The Muslim Brethren are now well-recognized for their foundational role in the Islamic revival which has now taken on new, and perhaps dangerous, life in recent times. After having been out of print for over a decade, this reissue of the classic work makes it accessible to a new generation of scholars and students interested in the Muslim revival—a group whose numbers have increased dramatically in the past decade. The new paperback edition has a foreword by John Voll, a leading American Islamic scholar, discussing the subsequent history and continued significance of the Muslim Brethren.
