Book excerpt: Volume One of The New Cambridge History of Islam, which surveys the political and cultural history of Islam from its Late Antique origins until the eleventh century, brings together contributions from leading scholars in the field. The book is divided into four parts. The first provides an overview of the physical and political geography of the Late Antique Middle East. The second charts the rise of Islam and the emergence of the Islamic political order under the Umayyad and the Abbasid caliphs of the seventh, eighth and ninth centuries, followed by the dissolution of the empire in the tenth and eleventh. 'Regionalism', the overlapping histories of the empire's provinces, is the focus of Part Three, while Part Four provides a cutting-edge discussion of the sources and controversies of early Islamic history, including a survey of numismatics, archaeology and material culture.
