One would expect to find the people rallying to the new order imposed by the Akkadian kings, especially since a feeling of national coherence did exist. The Sumerians had a phrase, “the black-headed people,” to designate themselves as an ethnic unit; and the gods Enlil and Anu, among others, were worshipped throughout the land. But this feeling had never found expression in a political form; it remained without effect, it seems, on the country’s history. The particularism of the cities was never overcome. At each new accession of a king in Akkad, the land rose in revolt. Far from rallying against the barbarians, the people attempted to revert to the local autonomy which had been the rule before the rise of Sargon. Similar conditions persisted throughout the country’s history. For example, the discoveries at Tell Asmar (ancient Eshnunna) illustrate the prevalence of local over national considerations. The ruler of that city collaborated with the Amorites who ravaged the country after the fall of the Third Dynasty of Ur; the barbarians were tolerated, and perhaps even assisted in their attacks on neighbouring towns, which were incorporated into the state of Eshnunna after the Amorites had looted them.[130] Under the Akkadian kings the tragic pattern of Mesopotamia’s history became visible. About 2180 B.C. their dynasty collapsed under the onslaught of the Guti from the Zagros Mountains. Combined invasions of Elamites and Amorites ended the empire of the Third Dynasty of Ur in 2025 B.C. The invasions of Hittites and Kassites ended the empire of Hammurabi’s dynasty in 1595 B.C. The invasion of the Medes destroyed the Assyrian empire (611 B.C.). The attack of Cyrus the Persian ended Neo-Babylonian rule (539 B.C.). The absence of safety and stability in the political field is entirely in keeping with the prevailing mood of the country. Mesopotamia achieved her triumphs in an atmosphere of deep disquiet. The spirit pervading her most important writings is one of disbelief in man’s ability to achieve lasting happiness. Salvation might be experienced emotionally in the annual festivals of the gods, but was not a postulate of theology. IV. EGYPT, THE KINGDOM OF THE TWO LANDS The ancient Egyptians said that Menes, who first ruled at This,[131] brought the whole of the land under his control. They designated him as the first king of a first dynasty and thus unequivocally marked the unification of their land as the beginning of their history. If we allow for the telescoping of events by which tradition often credits a single person with the achievements of two or more generations, we may say that archaeological discoveries have corroborated this tradition. The establishment of the single monarchy appears, indeed, as the political aspect of the birth of Egyptian civilization.
