This Volume One of a series on slaves and slavery in Muslim Africa. First published in 1985, it looks at Islam and the ideology of enslavement. Slaves of African origin formed a vital thread in the living lines of economic production in the Near and Middle East and formed the cord of economic activity in Islamic Africa itself. Slaves sustained the salt pits and date palms of desert societies; they worked the spice plantations of the East African littoral - became the porters and placemen in the trans-Saharan trade; and they constituted the entourage - the veritable wealth and currency - of the notables of Islamic societies.
