This book examines Salah ad-Din al-Ayyubi's efforts in dismantling the Fatimid state and liberating Jerusalem. It continues from previous works covering the eras of prophecy, the rightly guided caliphate, the Umayyad, Seljuk, Zengid, Almoravid, and Almohad dynasties, as well as the Ottoman Empire. This book, 'Salah ad-Din al-Ayyubi and His Efforts in Ending the Fatimid State and Liberating Jerusalem,' is a significant link in the chain of Crusades, which the Seljuks and Zengids emerged from. It discusses the clash of goals between the Crusader-Fatimid Shi'a plans and the Sunni Islamic project. The first chapter summarizes the Crusades before the rise of the Ayyubid state, while the second chapter covers the establishment of the Ayyubid state, focusing on the Battle of Hattin, the liberation of Jerusalem, and the Crusade. The book concludes with a summary followed by a list of the main references and sources used. • Author: Ali Muhammad Al-Sallabi • Publishing House: Dar Ibn Al-Jawzi - Cairo • Edition Number: 1 • Year of Printing: 2007 • Number of Pages: 592 • Number of Parts: 1 • Binding Type: Hardcover • Paper Type: Creamy • Printing Colors: Two colors • ISBN: 6222011501084
