An in-depth account of how competing understandings of Islam from the early sixteenth century onwards gradually led to the establishment of Twelver Shi'ism as the official religion of the Iranian state. A masterpiece, which cannot be ignored by anyone interested in the history of the Twelvers and of Iran more generally.' - The Muslim World Book Review 'A masterpiece, which cannot be ignored by anyone interested in the history of the Twelvers and of Iran more generally.' - The Muslim World Book Review
