Dedicated to the achievements of Farhad Daftary, the foremost authority in Ismaili Studies of our time, this volume gathers together a number of studies on intellectual and political history, particularly in the three main areas where the significance of Daftary’s scholarship has had the largest impact – Ismaili Studies as well as Persian Studies and Shi‘i Studies in a wider context. It focuses, but not exclusively, on the intellectual production of the Ismailis and their role in history, with discussions ranging from some of the earliest Ismaili texts, to thinkers from the Fatimid and the Alamut periods as well as relations of the Fatimids with other dynasties. Containing essays from some of the most respected scholars in Ismaili, Shi‘i and Persian Studies (including Patricia Crone, M. A. Amir-Moezzi, C. Edmund Bosworth and Robert Gleave), the book makes a significant contribution to wider scholarship in philosophical theology and medieval Islam. The contributors include: I. Afshar, H. Algar, M. A. Amir-Moezzi, S. J. Badakhchani, C. Baffioni, C. E. Bosworth, D. Cortese, P. Crone, D. De Smet, R. Gleave, H. Haji, I. Hajnal, A. H. Hamdani, C. Hillenbrand, A. C. Hunsberger, H. Landolt, L. Lewisohn, W. Madelung, A. Nanji, A. J. Newman, I. K. Poonawala and P. E. Walker.
