This book examines the origins of the concepts of Shia ism and Sunnism. It deals with the factors, personnel and circumstances that were most decisive in the creation and evolution of the two poles. The nature and scope of some early institutionalized Sunni-Shiah conflicts are also explored. The book is divided into three parts. In the first part, the origins of Shi ism between politics, creed and fanaticism are discussed. The question of whether there could be such thing as Sunni Shiaism , and what exactly that would entail, is also asked and meticulously answered. In the second part, the subject of the origins and evolution of the concept of Sunnism (ahl al-sunnah wa al-jama ah) is thoroughly examined. The religious, socio-political and historical contexts of the concept s development are investigated. Finally, in the third part, the role of the Shiah Fatimids in intensifying and cementing Sunni-Shiah conflicts, specifically at the level of institutions, and the immediate repercussions of such role, are looked into. To what extent the realms of art and architecture have been employed for the purpose are also investigated. Notwithstanding a few relatively sensitive aspects of the book, it has been researched and written in good faith. Nothing but an honest intellectual discourse was thereby intended, aiming to promote and advance the prospect of constructive Sunni-Shiah dialogue.
