"This book deals with aspects of Ismaili history and thought in medieval times. Discussing the different phases in Ismaili history, it describes both the early Ismailis as well as the contributions of the later Ismailis to Islamic culture. A number of chapters deal with Ismaili individuals such as Hasan-i Sabbah. Others chapters contextualise the Ismailis within the medieval Muslim societies, in addition to investigating the Ismaili-Crusader relations and the resulting myths and legends about the Ismailis." The essays collected in this volume, representing the results of modern scholarship in Ismaili studies, make a powerful contribution to our understanding of an Islamic community in medieval times and will prove invaluable to historians and scholars of the Muslim world.
