Since its first publication in 1969, this book continues to be routinely cited as the standard source for the history of the revivalist Egyptian movement, the Muslim Brethren, up to the time of Nasser. This classic work is now accessible to a new generation of scholars and students interested in the Muslim revival. Professor John Voll of the University of New Hampshire, a leading scholar of Islam in the English speaking world, contributes a Foreword to the paperback edition.
