Prof. Dr. Mustafa Demirci's monograph "Black Rage: The Rebellion of Negro Slaves in the Medieval Islamic World (869-883)" on the 'Zanj rebellion' that took place between 869-883 A.D., during the Abbasid period, and was led by the Ali b. Muhammad, is one of the most important studies both in terms of its subject matter and the author's approach and perspective on the subject. The study, which was prepared with a rich academic literature using basic sources and modern research on the (...) subject, deals with issues such as the geography of the event, the causes and spread of the rebellion, the wars and warfare techniques to suppress the rebellion, the short and long-term effects of the damage left behind by the rebellion from an academic perspective in chronological order. The Zanj revolt started in the marshes of Basra in 869 as a result of Ali b. Muhammad (d. 883), who was originally white and claimed to be a descendant of Ali, organizing black slaves working under difficult conditions in the large farms in and around Basra, and the rebellion grew and spread in a short time. Muwaffak Billāh (843-891), the brother of the Abbasid Caliph Mu’temid Alallâh (843-892), who was assigned to suppress the revolt, was victorious against the rebels after tough struggles, and the revolt ended with the killing of the leader of the rebellion, Ali b. Muhammad, in 883. (shrink)
