In the course of these ten years it is probable that Dungi annexed the greater part of Elam, and placed his empire upon an enduring basis. It is true that during the closing years of his reign he undertook a fresh series of expeditions, conquering Shashru in the fifty-second year, subduing Simuru and Lulubu in the fifty-fourth year "for the ninth time," and Urbillu, Kimash, Khumurti and Kharshi in the course of his last four years. But the earlier victories, by means of which he extended his sway far beyond the borders of Sumer and Akkad, may be held to mark the principal era of expansion in the growth of his empire. It was probably during this period that he added to his other titles the more comprehensive one of "king of the four quarters (of the world)," thus reviving a title which had already been adopted by Narâm-Sin at a time when the empire of Akkad had reached its zenith. Another innovation which Dungi introduced in the course of his reign, at a period it would seem shortly before his adoption of Narâm-Sin's title, was the assumption of divine rank, indicated by the addition of the determinative for divinity before his name. Like Narâm-Sin, who had claimed to be the god of Akkad, he styled himself the god of his land, and he founded temples in which his statue became the object of a public cult. He also established a national festival in his own honour, and renamed the seventh month of the year, during which it was celebrated, as the Month of the Feast of Dungi. He appears to have been the first Sumerian ruler to claim divine honours. By so doing he doubtless challenged comparison with the kings of Akkad, whose empire his conquests had enabled him to rival.
