This book offers a new interpretation to the social history of religion in Iran from the 1870s to the 1970s. It aims to situate the 'revolutionary' upheavals of 1977-82 in an extensive narrative context of historical developments over the preceding century, and to relate the 'religious' elements in that history to other social and cultural issues. In the author's analysis, Iran's revolution was complex, and contingent on a range of factors rather than a simple or inevitable outcome of the nature of the Iranian state or the nature of religion in Iran. The focus of the argument is on the human responses of Iranians to their experiences and problems in all their diversity and on the rich variety and complexity of relationships between religion and other aspects of life, thought and culture in the daily life of Iranians.
