Book excerpt: This pioneer study presents a quantitative analysis of the civilian elite in Mamluk Cairo. Using information about 4,631 individuals drawn from two fifteenth-century biographical dictionaries, Carl Petry explores the geographic origins of the civilian elite (the 'ulama') and the distribution of their residences and places of work in Cairo.
