Much evidence – textual, material and documentary – points to slavery in the early and medieval Islamic Middle East (c. 600-1000 CE) as a social fact, persistent and multivalent. This is especially true for the urban landscape: the presence of enslaved and freed persons would have been impossible to miss. More difficult is the reconstruction of Middle Eastern agrarian slavery. This is a survey essay with particular reference to the early Abbasid Caliphate (c. 750-950) and select questions around which debate in modern scholarship has grown. One must comb medieval Arabic texts (literary and documentary) to reconstruct patterns of early Islamic-era enslavement; the organization and dynamics of slave commerce; the demands on slave and freed labor; and the (relative) social integration of the enslaved. The Arabic/Islamic library illuminates all manner of topics, religious and secular alike. Literary references to slavery and/or enslaved persons therein are plentiful and of a great variety. One has references in works of poetry and adab, an elastic term used for a variety of Arabic prose writings. Equally numerous are references in chronicles, biographical dictionaries, and works of geography and political thought. Medieval Arabic legal and religious writings provide a considerable number of references as well.
