Already, in the reign of Manishtusu, Akkad and her citizens had enjoyed a position of great influence in the kingdom of Kish, and it is not surprising that in the course of a few generations she should have obtained the hegemony in Babylonia. We do not know the immediate cause of the change of capital, nor whether it was the result of a prolonged period of antagonism between the rival cities. On this point the later tradition is silent, merely recording that Sargon obtained "the kingdom" through Ishtar's help. That Shar-Gani-sharri was the actual founder of his dynasty is clear from the inscription upon his gate-sockets found at Nippur, which ascribe no title to his father, Dâti-Enlil,[49] proving that his family had not even held the patesiate or governorship of Akkad under the suzerainty of Kish. Indeed, tradition related that Sargon's native city was Azupirânu, and it loved to contrast his humble birth and upbringing with the subsequent splendour of his reign. The legend of his committal to the river in an ark of bulrushes, and of his rescue and adoption by Akki, the gardener, would make its appeal to every later generation, and it undoubtedly ensured for Sargon the position of a national hero in the minds of the people. The association of the story with his name, while tending to preserve his memory, need not be held to discredit the traditions of his conquests, which, as we have already seen, are confirmed in several important details by the inscriptions of his reign. On the transference of power from Kish to Akkad an expansion of Semitic authority from Northern Babylonia appears to have taken place throughout a considerable portion of Western Asia. Elam no longer claims the principal share of attention from the rulers of Akkad and Sumer, and Shar-Gani-sharri seems to have devoted his energies to extending his influence northwards and, more particularly, in the west. Kutû, which lay to the north-east of Akkad, in the hilly country on the east of the Lower Zâb, was conquered in the same year that Shar-Gani-sharri laid the foundations of the temples of Anunitu and Amal in Babylon, and Sharlak, its king, was taken captive.[50] The reference to this event in the official title of the year during which it took place is some indication of the importance ascribed to the campaign. Unfortunately, we possess no classified date-list for the Dynasty of Akkad, such as we have recovered for the later Dynasties of Ur and Babylon, and the dated tablets of this period are too few to enable us to attempt any chronological classification of them by their contents. We are thus without the means of arranging Shar-Gani-sharri's conquests in the order in which they took place, or of tracing the steps by which he gradually increased his empire. But if the order of the sections on the Omen-tablet has any significance, it would seem that his most important conquest, that of Amurru or "the Western Land," took place in the earlier years of his reign.
