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. Originally published in 1982. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
