Uncertainty again shrouds the history of the country after Sovkhotpû I.: not that monuments are lacking or names of kings, but the records of the many Sovkhotpûs and Nonrhotpûs found in a dozen places in the valley, furnish as yet no authentic means of ascertaining in what order to classify them. The XIIIth dynasty contained, so it is said, sixty kings, who reigned for a period of over 453 years.* * This is the number given in one of the lists of Manetho, in Muller-Didot, _Fragmenta Historicorum Græcorum_, vol. ii. p. 565. Lepsius’s theory, according to which the shepherds overran Egypt from the end of the XIIth dynasty and tolerated the existence of two vassal dynasties, the XIIIth and XIVth, was disputed and refuted by E. de Rougé as soon as it appeared; we find the theory again in the works of some contemporary Egyptologists, but the majority of those who continued to support it have since abandoned their position. The succession did not always take place in the direct line from father to son: several times, when interrupted by default of male heirs, it was renewed without any disturbance, thanks to the transmission of royal rights to their children by princesses, even when their husbands did not belong to the reigning family. Monthotpû, the father of Sovkhotpu III., was an ordinary priest, and his name is constantly quoted by his son; but solar blood flowed in the veins of his mother, and procured for him the crown. The father of his successor, Nofirhotpû IL, did not belong to the reigning branch, or was only distantly connected with it, but his mother Kamâît was the daughter of Pharaoh, and that was sufficient to make her son of royal rank. With careful investigation, we should probably find traces of several revolutions which changed the legitimate order of succession without, however, entailing a change of dynasty. The Nofirhotpûs and Sovkhotpûs continued both at home and abroad the work so ably begun by the Amenemhâîts and the Usirtasens.
