The Crisis of the Imamate and the Institution of Occultation in Twelver Shiʿism: A Sociohistorical Perspective

The formative period of Imami Shiʿism from the mid-8th century to the mid-10th century remains obscure in many respects. This study is an attempt to organize the historical information about the period around a central problematic: the twin crisis of the nature of the Imamate and the succession to this office. The crisis of the Imamate and the efforts to resolve it serve as a focal point for constructing a conceptually coherent overview of these two formative centuries from a sociohistorical perspective. This perspective requires that the endeavors to create a stable system of authority in Imami Shiʿism be considered in the context of the social change and politics of the early ʿAbbasid era: ʿAlid–ʿAbbasid relations, massive conversion of the population of Iran to Islam, and the dialogue and competition between Shiʿism and other contemporary religious and intellectual trends and movements. Our approach suggests a new periodization of the early history of Imami Shiʿism.
