Unfortunately our knowledge of Sargon's reign is of meagre character. It is undoubted that he was a distinguished general and able ruler. He built up an empire which included Sumer and Akkad, and also Amurru, "the western land", or "land of the Amorites". The Elamites gave him an opportunity to extend his conquests eastward. They appear to have attacked Opis, but he drove them back, and on more than one occasion penetrated their country, over the western part of which, known as Anshan, he ultimately imposed his rule. Thither went many Semitic settlers who had absorbed the culture of Sumeria.
During Sargon's reign Akkad attained to a splendour which surpassed that of Babylon. In an omen text the monarch is lauded as the "highly exalted one without a peer". Tradition relates that when he was an old man all the Babylonian states rose in revolt against him and besieged Akkad. But the old warrior led forth his army against the combined forces and achieved a shattering victory.
Manishtusu, who succeeded Sargon I, had similarly to subdue a great confederacy of thirty-two city states, and must therefore have been a distinguished general. But he is best known as the monarch who purchased several large estates adjoining subject cities, his aim having been probably to settle on these Semitic allies who would be less liable to rebel against him than the workers they displaced. For the latter, however, he found employment elsewhere. These transactions, which were recorded on a monument subsequently carried off with other spoils by the Elamites and discovered at Susa, show that at this early period (about 2600 B.C.) even a conquering monarch considered it advisable to observe existing land laws. Urumush,[[148]] the next ruler, also achieved successes in Elam and elsewhere, but his life was cut short by a palace revolution.
The prominent figure of Naram Sin, a later king of Akkad, bulks largely in history and tradition. According to the Chronicle of Kish, he was a son of Sargon. Whether he was or not, it is certain that he inherited the military and administrative genius of that famous ex-gardener. The arts flourished during his reign. One of the memorable products of the period was an exquisitely sculptured monument celebrating one of Naram Sin's victories, which was discovered at Susa. It is one of the most wonderful examples of Babylonian stone work which has come to light.
A successful campaign had been waged against a mountain people. The stele shows the warrior king leading his army up a steep incline and round the base of a great peak surmounted by stars. His enemies flee in confusion before him. One lies on the ground clutching a spear which has penetrated his throat, two are falling over a cliff, while others apparently sue for mercy. Trees have been depicted to show that part of the conquered territory is wooded. Naram Sin is armed with battleaxe and bow, and his helmet is decorated with horns. The whole composition is spirited and finely grouped; and the military bearing of the disciplined troops contrasts sharply with the despairing attitudes of the fleeing remnants of the defending army.
During this period the Semitized mountaineers to the north-east of Babylonia became the most aggressive opponents of the city states. The two most prominent were the Gutium, or men of Kutu, and the Lulubu. Naram Sin's great empire included the whole of Sumer and Akkad, Amurru and northern Palestine, and part of Elam, and the district to the north. He also penetrated Arabia, probably by way of the Persian Gulf, and caused diorite to be quarried there. One of his steles, which is now in the Imperial Ottoman Museum at Constantinople, depicts him as a fully bearded man with Semitic characteristics. During his lifetime he was deified--a clear indication of the introduction of foreign ideas, for the Sumerians were not worshippers of kings and ancestors.
Naram Sin was the last great king of his line. Soon after his death the power of Akkad went to pieces, and the Sumerian city of Erech again became the centre of empire. Its triumph, however, was shortlived. After a quarter of a century had elapsed, Akkad and Sumer were overswept by the fierce Gutium from the north-eastern mountains. They sacked and burned many cities, including Babylon, where the memory of the horrors perpetrated by these invaders endured until the Grecian Age. An obscure period, like the Egyptian Hyksos Age, ensued, but it was of comparatively brief duration.
When the mists cleared away, the city Lagash once more came to the front, having evidently successfully withstood the onslaughts of the Gutium, but it never recovered the place of eminence it occupied under the brilliant Ur-Nina dynasty. It is manifest that it must have enjoyed under the various overlords, during the interval, a considerable degree of independence, for its individuality remained unimpaired. Of all its energetic and capable patesis, the most celebrated was Gudea, who reigned sometime before 2400 B.C. In contrast to the Semitic Naram Sin, he was beardless and pronouncedly Sumerian in aspect. His favoured deity, the city god Nin-Girsu, again became prominent, having triumphed over his jealous rivals after remaining in obscurity for three or four centuries. Trade flourished, and the arts were fostered. Gudea had himself depicted, in one of the most characteristic sculptures of his age, as an architect, seated reverently with folded hands with a temple plan lying on his knees, and his head uplifted as if watching the builders engaged in materializing the dream of his life. The temple in which his interests were centred was erected in honour of Nin-Girsu. Its ruins suggest that it was of elaborate structure and great beauty. Like Solomon in later days, Gudea procured material for his temple from many distant parts--cedar from Lebanon, marble from Amurru, diorite from Arabia, copper from Elam, and so forth. Apparently the King of Lagash was strong enough or wealthy enough to command respect over a wide area.
Another city which also rose into prominence, amidst the shattered Sumerian states, was Ur, the centre of moon worship. After Gudea's death, its kings exercised sway over Lagash and Nippur, and, farther south, over Erech and Larsa as well. This dynasty endured for nearly a hundred and twenty years, during which Ur flourished like Thebes in Egypt. Its monarchs styled themselves as "Kings of the Four Regions". The worship of Nannar (Sin) became officially recognized at Nippur, the seat of Enlil, during the reign of King Dungi of Ur; while at Erech, the high priest of Anu, the sky god, became the high priest of the moon god. Apparently matriarchal ideas, associated with lunar worship, again came into prominence, for the king appointed two of his daughters to be rulers of conquered states in Elam and Syria. In the latter half of his reign, Dungi, the conqueror, was installed as high priest at Eridu. It would thus appear that there was a renascence of early Sumerian religious ideas. Ea, the god of the deep, had long been overshadowed, but a few years before Dungi's death a temple was erected to him at Nippur, where he was worshipped as Dagan. Until the very close of his reign, which lasted for fifty-eight years, this great monarch of tireless activity waged wars of conquest, built temples and palaces, and developed the natural resources of Sumer and Akkad. Among his many reforms was the introduction of standards of weights, which received divine sanction from the moon god, who, as in Egypt, was the measurer and regulator of human transactions and human life.
To this age also belongs many of the Sumerian business and legal records, which were ultimately carried off to Susa, where they have been recovered by French excavators.
