This volume presents a selection of the key studies in which leading scholars since the beginning of the 20th century attempt to explain the phenomenally rapid expansion of the early Islamic state during the 7th century CE. The articles debate the causes for the conquest movement or expansion, the reasons for its success, the nature of the movement itself, the impact the expansion had on the countries affected by it, and the complex questions surrounding the sources on which historians have constructed their views of the expansion, and the reliability (or lack of it) of those sources. No articles devoted to the actual conquest of a given locality are included-hundreds exist-but a fairly extensive bibliography lists many of the more important contributions in this genre. The editor's introduction addresses the phenomenon of the expansion and how scholars have approached and grappled with it.

The origins of Islam have been the subject of increasing controversy in recent years. The traditional view, which presents Islam as a self-consciously distinct religion tied to the life and revelations of the prophet Muhammad in western Arabia, has since the 1970s been challenged by historians engaged in critical study of the Muslim sources. In Muhammad and the Believers, the eminent historian Fred Donner offers a lucid and original vision of how Islam first evolved. He argues that the origins of Islam lie in what we may call the "Believers' movement" begun by the prophet Muhammad-a movement of religious reform emphasizing strict monotheism and righteous behavior in conformity with God's revealed law. The Believers' movement thus included righteous Christians and Jews in its early years, because like the Qur'anic Believers, Christians and Jews were monotheists and agreed to live righteously in obedience to their revealed law. The conviction that Muslims constituted a separate religious community, utterly distinct from Christians and Jews, emerged a century later, when the leaders of the Believers' movement decided that only those who saw the Qur'an as the final revelation of the One God and Muhammad as the final prophet, qualified as Believers. This separated them decisively from monotheists who adhered to the Gospels or Torah.

This is the first translation of a classic work (Bahth fi nnsh' at 'ilm al ta' rikh 'inda l-'Arab) by the eminent Arab historian A. A. Duri. Published in Beirut in 1960, Duri's book was the first comprehensive effort to trace the origins and early development of Arab historical writing, and to resolve some extremely complex and still debated questions about the reliability of the Arabic historical sources.

In this contribution to the ongoing debate on the nature and causes of the Islamic conquests in Syria and Iraq during the sixth and seventh centuries, Fred Donner argues for a necessary distinction between the causes of the conquests, the causes of their success, and the causes of the subsequent Arab migrations to the Fertile Crescent.

This volume reprints nineteen articles that deal with the formation of the first Islamic state under the 'rightly-guided' and Umayyad caliphs (632-750 CE). The articles (five of which originally appeared in languages other than English and are translated here) trace the crystallization of key institutions of the growing empire and treat such fundamental issues as taxation, military institutions, administrative organization and practices, the barid or official courier and intelligence service, succession, the ruling elites and their income, and questions of legitimation. The volume includes an introduction by the editor that offers an overview of the processes involved and helps place each article in its proper context. It also offers an extensive bibliography of further works relevant to the theme of the volume.
