Jews lived in Egypt over many centuries, from biblical times until the middle of the previous century. Nevertheless, Jewish life in medieval Islamic Egypt was for many years an obscure and understudied theme. The present book offers the reader a wide-ranging picture of Jewish life in medieval Egypt as depicted by most recent scholarship. Starting from the last phases of the Byzantine era and ending with the Mamluk period, the book presents a scholarly yet vivid description of Jewish communal organization, judiciary, economic frameworks, family life, and lingual practices, as well as religious and literary activities of the medieval Jews of Egypt.
