In the end the kings of Thebais, and of other provinces of Egypt, arose against the Shepherds, and a long and mighty war was carried on between them, until the Shepherds were overcome by a king whose name was Misphragmouthosis, who, having expelled them from other parts of Egypt, shut them up in Avaris, a tract consisting of about 10,000 acres. All this tract the Shepherds fortified with great strength, whilst Thummosis, son of Misphragmouthosis, tried to force them to surrender by a siege, and surrounded them with an army of 480,000 men. He was beginning to despair of being able to reduce them, when they agreed to capitulate, stipulating that they should be permitted to leave Egypt, and go with all their families whithersoever they pleased. This was agreed to, and they bent their way through the desert towards Syria. Fearing the Assyrians (Babylonians), however, who then had dominion over Asia, they built a city in the country called Judea, of sufficient size to contain them all (they numbered not less than 240,000), and named it Jerusalem. From this it would appear that, taking advantage of the disorganized state of Egypt about 2100 years before Christ, these Shepherd kings invaded the country, and gradually consolidated their power there. In process of time they had the whole of the country in their possession, and such rulers as remained were allowed to retain their provinces only as vassals, being really princes only in name. It is also very probable that if, as really appears, they were barbarians on entering Egypt, they became civilized by intercourse with the nation which they had conquered. This having been done, the monarchy which they established conformed more and more with that of the native Egyptian kings, so that their court and manner of administration were, to all intents and purposes, Egyptian; native administrators being appointed to many important posts in order to obtain the willing obedience of the people.
