A Short History of the Fatimid Khalifate

"A Short History of the Fatimid Khalifate" by De Lacy O'Leary is a historical account written in the early 20th century. This work outlines the history of the Fatimid Khalifs, particularly focusing on their governance in Egypt during the time of the First and Second Crusades. The author draws from Arabic and Persian historians to provide a nuanced perspective of the Fatimid dynasty and its significance in the context of both Eastern and Western historical narratives. At the start of the book, the author sets the stage for understanding the emergence of the Fatimid Khalifate, delving into the roots of Shi'ite Islam and the emergence of various sects, including Isma'ili and Qarmatians. He explains how these sects formed in response to political and theological disputes and positions the Fatimids as a significant force that emerged as a rival to the Abbasid Khalifate. O'Leary emphasizes the need for a richer understanding of the dynamics between the Islamic world and the Crusading West, arguing that a more comprehensive study of the Fatimids is essential for a complete view of medieval history.
