Of the available sources for Islamic history between the seventh and eighth centuries CE, few are of greater importance than al-Baladhuri's Kitab Futuh al-buldan (The Book of the Conquest of Lands). Written in Arabic by a ninth-century Muslim scholar working at the court of the 'Abbasid caliphs, the Futuh's content covers many important matters at the beginning of Islamic history. It informs its audience of the major events of the early Islamic conquests, the settlement of Muslims in the conquered territories and their experiences therein, and the origins and development of the early Islamic state. Questions over the text's construction, purpose, and reception, however, have largely been ignored in current scholarship. This is despite both the text's important historical material and its crucial early date of creation. It has become commonplace for researchers to turn to the Futuh for information on a specific location or topic, but to ignore the grander – and, in many ways, more straightforward – questions over the text's creation and limitations. This book looks to correct these gaps in knowledge by investigating the context, form, construction, content, and early reception history of al-Baladhuri's text.
