Even inthe time of Amenofches III. they had endeavoured to reap profit from the discords of Mitanni, and had asserted their supremacy over it. Dushratta, however, was able to defeat one of their chiefs. Repulsed on this side, they fell back upon that part of Naharaim lying between the Euphrates and Orontes, and made themselves masters of one town after another in spite of the despairing appeals of the conquered to the Theban king. From the accession of Khuniatonu, they set to work to annex the countries of Nukhassi, Nii, Tunipa, and Zinzauru: they looked with covetous eyes upon Phoenicia, and were already menacing Coele-Syria. The religious confusion in Egypt under Tutankhamon and Ai left them a free field for their ambitions, and when Harmhabi ventured to cross to the east of the isthmus, he found them definitely installed in the region stretching from the Mediterranean and the Lebanon to the Euphrates. Their then reigning prince, Sapalulu, appeared to have been the founder of a new dynasty: he united the forces of the country in a solid body, and was within a little of making a single state out of all Northern Syria.* * Sapalulu has the same name as that wo meet with later on in the country of Patin, in the time of Salmanasar III., viz. Sapalulme. It is known to us only from a treaty with the Khati, which makes him coeval with Ramses I.: it was with him probably that Harmhabi had to deal in his Syrian campaigns. The limit of his empire towards the south is gathered in a measure from what we know of the wars of Seti I. with the Khati. All Naharaim had submitted to him: Zahi, Alasia, and the Amurru had passed under his government from that of the Pharaohs; Carchemish, Tunipa, Nii, Hamath, figured among his royal cities, and Qodshu was the defence of his southern frontier. His progress towards the east was not less considerable. Mitanni, Arzapi, and the principalities of the Euphrates as far as the Balikh, possibly even to the Khabur,* paid him homage: beyond this, Assyria and Chaldaea barred his way. Here, as on his other frontiers, fortune brought him face to face with the most formidable powers of the Asiatic world. * The text of the poem of Pentauirit mentions, among the countries confederate with the Khati, all Naharaim; that is to say, the country on either side of the Euphrates, embracing Mitanni and the principalities named in the Amarna correspondence, and in addition some provinces whose sites have not yet been discovered, but which may be placed without much risk of error to the north of the Taurus.
