The interaction between Muslims and the other religious denominations of the Middle East in the period 620-1020 is the subject of this volume. This is arguably the single most important issue in the history of the early Islamic Middle East, since the Muslims were initially a minority in the lands that they had conquered and so had to reach some modus vivendi with the various religious communities in their realm. Fifteen articles by leading scholars shed light on this process from a number of different perspectives: historical, conceptual, legal, social and theological. An introduction both gives an overview and examines possibilities for future research. The period under study is demarcated at one end by the Prophet Muhammed (d. 632) who, as the Qur'an tells us, had to deal with Jews, Christians and polytheists. At the other end lies the great legal/political thinker Manardi (d. ca. 1020), by whose time the Middle East had become substantially Islamicised.
