The Ismaili Muslims, who belong to the Shia branch of Islam, live in over 25 different countries around the world, mainly in Asia, Africa and the Middle East. Their history has typically been linked to the history of the various countries in which they live, but the worldwide community is united under Prince Karim Aga Khan, the spiritual leader and 49th Imam of the Ismaili Muslims. Few fields of Islamic studies have witnessed as drastic a change as Ismaili studies, due in part to the recent discovery of numerous historical texts, and author Farhad Daftary makes extensive use of these new sources in the Historical Dictionary of the Ismailis. This comprehensive new reference work is the first of its kind on the Ismailis and presents a summary of the findings of modern scholarship on the Ismaili Shia Muslims and different facets of their heritage. The dictionary covers all phases of Ismaili history as well as the main doctrines of the community. It includes an introductory chapter, which provides a broad historical survey of the Ismailis, followed by alphabetical entries on all major aspects of the community, such as key figures, institutions, traditions, and doctrines. It also contains a chronology, genealogical tables, a glossary, and a substantial bibliography. This book is an excellent access point for students, researchers, and anyone wanting to know more about the Ismailis.
