The dynastic history of ancient Egypt extends, at the lowest computation, over a period of more than three thousand years. In view of chronological difficulties, it has been found convenient to adopt the dynastic system of reckoning chosen by Manetho, an Egyptian priest who lived in the third century before Christ. Manetho divided the history of Egypt into thirty-one dynasties, of which some twenty-six comprise the period between Mena's Conquest and the Persian Conquest, while the others cover the period of Persian, Hellenic, and Latin supremacy. With the Persian Conquest, however, came the disintegration of the Egyptian Empire, and at that point purely native history comes to an end.
Though Manetho's dynastic divisions have been adopted by modern Egyptologists, his chronology is not so well received, though it is supported by at least one distinguished authority—Professor Flinders Petrie. The general tendency at the present day is to accept the minimum chronology which is known as that of the Berlin School, which places Mena's Conquest at 3400 B.C. and the Twelfth Dynasty about 2000 B.C., rather than that of Professor Petrie, which would place these events at 5500 B.C. and 3400 B.C. respectively. It is customary to group the various dynasties into three periods—the Old Kingdom, comprising Dynasties I to VIII; the Middle Kingdom, Dynasties IX to XVIII; and the New Empire, Dynasties XVIII to XXVI. These divisions, however, do not imply any break in the course of Egyptian history, but are merely used for the sake of convenience. The following Table compares the systems of dating in vogue with students of Egyptian history, according to Professor Petrie and the Berlin School, as represented by Professor Breasted:
