The rise and establishment of Safavid rule in Iran is a clear and momentous event in the wider history of the Middle East and Islamic world. In this study, Hani Khafipour explores how loyalty, social cohesion, and power dynamics found in Sufi thought underpinned the Safavid community's sources of social power and determination. Once in power, the Safavid state's patronage of art, literature, and architecture, turned Iran into a flourishing empire of culture, influencing neighboring empires including the Ottomans and Mughals. Examining the origin and evolution of the Safavid order, Mantle of the Sufi Kings offers fresh insights into how religious and sociopolitical forces merged to create a powerful Shi'i empire, with Iran remaining the only Shi'i nation in the world today. This study provides a bold new interpretation of Iran's early modern history, with important implications for the contemporary religio-political discourse in the Middle East.
