An original exploration into the governors of Egypt under the caliphs, this seminal study of Wüstenfeld has remained essential reading on the topic since its original publication in the 1870s. Originally published in four parts, this edition contains the entire study in its original German. A thorough and meticulous record of the rulers of Egypt during the period of the caliphs, this book should not be overlooked by students of the Islamic culture of Egypt. Written from a lifetime of study in the field, Wüstenfeld’s sharp outlines of the governors and their influence in the growth and development of Egypt under Muslim leadership hold an authority and insight that make the book a desirable addition to the library of Arabists and scholars of Egypt alike.
