The Egyptians had no need to anticipate Chaldæan interference when, forsaking their ancient traditions, they penetrated for the first time into the heart of Syria. Babylonian rule ceased to exercise direct control when the line of sovereigns who had introduced it disappeared. When Ammisatana died, about the year 2099 B.C., the dynasty of Khammurabi became extinct, and kings of the semi-barbarous Cossæan race gained the throne which had been occupied since the days of Khammurabi by Chaldæans of the ancient stock. The Cossæan king who seized on Babylon was named Gandish. He and his tribe came from the mountainous regions of Zagros, on the borders of Media. The Cossæan rule over the countries of the Euphrates was doubtless similar in its beginnings to that which the Hyksos exercised at first over the nomes of Egypt. The Cossæan kings did not merely bring with them their army, but their whole nation, who spread over the whole land. As in the case of the Hyksos, the barbarian conquerors thus became merged in the more civilised people which they had subdued. But the successors of Gandish were unable permanently to retain their ascendancy over all the districts and provinces, and several of these withdrew their allegiance. Thus in Syria the authority of Babylon was no longer supreme when the encroachments of Egypt began, and when Thutmosis entered the region the native levies which he encountered were by no means formidable. The whole country consisted of a collection of petty states, a complex group of peoples and territories which the Egyptians themselves never completely succeeded in disentangling. We are, however, able to distinguish at the present time several of these groups, all belonging to the same family, but possessing different characteristics--the kinsfolk of the Hebrews, the children of Ishmæl and Edom, the Moabites and Ammonites, the Arameans, the Khati and the Canaanites. The Canaanites were the most numerous, and had they been able to confederate under a single king, it would have been impossible for the Egyptians to have broken through the barrier thus raised between them and the rest of Asia. _III.--The Eighteenth Theban Dynasty_
