Until recently, social movement theory and research focused almost entirely on Western movements. Social Movements in Twentieth-Century Iran shows how one set of movements 'worked' where the state, other structural elements, and culture differed dramatically from the West, even while Western ideas and meddling shaped them. Poulson's highly readable book is important for students of social movements and also for others who want to better understand this country that is so closely related to current global conflicts yet so crudely caricatured in our media.
