In recent years, Islamic fundamentalist, revolutionary, and jihadist movements have overshadowed more moderate and reformist voices and trends within Islam. This compelling volume introduces the current generation of reformist thinkers and activists, the intellectual traditions they carry on, and the reasons for the failure of reformist movements to sustain broad support in the Islamic world today. Richly detailed regionally focused chapters cover Iran, the Arab East, the Maghreb, South Asia, Indonesia, Malaysia, Turkey, Europe, and North America. The editor's introductory chapter traces the roots of reformist thinking both in Islamic tradition and as a response to the challenge of modernity for Muslims struggling to reconcile the requirements of modernization with their cultural and religious values. The concluding chapter identifies commonalities, comparisons, and trends in the modernizing movements.
