The new cycle of urbanization encompassed an enlarged horizon and was based on a deeper rooting in the society. The urban cultures spread again from Lower Mesopotamia in the so-called Early Dynastic period, about 2800-2350 bce, to include Upper Mesopotamia, the Levant, Anatolia, and Elam. The spread of cuneiform writing in most of these regions, except Anatolia and Palestine, makes the interconnections more visible. The adjacent areas also underwent similar processes of growth and consolidation in Old Kingdom Egypt, in the Early Harappan civilization of the Indus Valley, and in northeastern Iran and Central Asia. All these areas were linked together by trade contacts and cultural cross-fertilization.
The large size of the area involved and the spread of writing made the ethnic diversity much clearer than in the previous period. Lower Mesopotamia hosted two different linguistic groups: the Sumerians prevailed in the south, or Sumer, and the Semites in the north, or Akkad. The two groups, although coexisting in the same polities, differed not only in language and other cultural traits (for example, the style of figurative arts) but also in basic social and political features. The heritage of the temple-city was characteristic of Sumer, while in the Semitic area the influence of the kinship groups and pastoral tribes was more visible. In Upper Mesopotamia the prevailing population was Hurrian, and in Susiana and Anshan, the later Fars, it was Elamite. In Syria an early stage of the later northwest Semitic dialects was represented by Eblaite. For Anatolia we lack direct evidence, but the analysis of later languages and personal names makes us believe that the area was inhabited by Hattians and other non-Indo-European peoples.
The typical polity was the city-state in the densely inhabited regions of the lowlands, and probably some kind of ‘‘ethnic’’ state among the mountaineers and the steppe-dwellers. In the Sumerian south, the city-state was basically a ‘‘temple-city’’ as already described in the Uruk period, although the royal palace acquired a separate political role, leaving to the temples the role of managerial agencies of the economy in addition to their cultic role. The city leader in the south was usually a ‘‘priest-king’’ (e n), or a ‘‘city administrator’’ (e n s i), the ideology leaving the role of the true sovereign to the city god. The temple-city was in theory the property of the god, and was in practice a state centered on the city and dominating a rural landscape of some 10 to 20 km or 6 to 12 miles in radius. The major Sumerian city-states of the period were Ur, whose ‘‘Royal Cemetery’’ provides the most brilliant image of wealth and craftsmanship, Uruk, Eridu, Umma, Lagash, Adab, and Shuruppak. Between the Sumerian south and the Akkadian north, the city of Nippur played a special role as seat of the leading god of the Sumerian pantheon, Enlil - a role of providing political legitimacy to kings who held the city and of providing a symbol of cultural unity for Sumer in the theory that only one king could be paramount at any one time. At an early stage of development, in Early Dynastic II, a ‘‘league’’ of Sumerian cities seems to have played an important political role. More often, competition for agricultural lands could spark wars among neighboring cities, and the long war between Lagash and Umma in Early Dynastic III is well known from the royal inscriptions of Lagash. But the equilibrium between the various city-states seems to have been resistant to imbalance.
In the area of Akkad city-states like Eshnunna or Akshak seem to have shared the southern model. But the most important city, Kish, was formed differently, with a neat prevalence of the palace over the temple, with a larger territory, with a warlike king (l u g a l ‘‘big man’’), and clear expansionistic intent. It is possible that ethnicity had some influence in generating the two different models, but certainly the ecological and economic basis was also a factor. In the north pastoralism was more important, and agriculture was less dependent on irrigation, with local systems of square fields prevailing over the temple-run sets of elongated fields in the south. The modified model also spread to Upper Mesopotamia: along the middle Tigris (at Assur) and the Middle Euphrates (at Mari), in the Jazira (at Tell Brak/Nagar and other centers), and in Syria (at Ebla).
Various administrative archives have been recovered, both in the south (Ur ‘‘archaic’’ in Early Dynastic II, about 2700-2600; Fara in Early Dynastic IIIa, about 2600-2450; and especially Lagash in Early Dynastic IIIb, about 2450-2350), and more recently in the north (Mari, Tell Beydar) and Syria (Ebla, about 2500-2350). The two major archives, Lagash and Ebla, have been correctly contrasted as representing different socio-economic systems. In fact the economy of Lagash was managed through a system of temples, by a class of priestly administrators, and was mostly based on intensive agriculture. Ebla was managed by the palace, with an important role left to the representatives of kin groups and local communities, and it was based on mixed agricultural and pastoral production and on long-distance trade in metals and textiles. The temples at Ebla were devoted to cultic activities and ceremonial redistribution, but nothing comparable to the administrative redistribution of the Sumerian temples.
The competition among the various trade networks was an important factor. Apart from local exchange in city markets and fairs, long-distance trade was especially important in the cities located between the river valleys and their periphery from which most of the raw materials came: Susa trading with the Iranian plateau, Assur with the upper Tigris and Anatolia, Abarsal with the upper Euphrates, Mari and Ebla with Syria. Trade was carried on with caravans of donkeys by merchants dependent on and financed by central agencies. Relationships between merchants and palace or temple were of the ‘‘administrative’’ kind, with fixed prices and a system of yearly accounts, the value of the imported goods being balanced against the value of entrusted goods. But when outside the area of control of the central agency, the merchants were free to negotiate for profit, and could also use their money for loans at interest and loans with personal guarantees.
The competition in trade networks was a factor in the struggles between the most important city-states, especially during the final phase of the Early Dynastic III. In some cases the competition was settled by agreement and delimitation of the respective networks as in the treaty between Ebla and Abarsal, in other cases by recourse to war as between Mari and Ebla. The rise of a new polity in central Mesopotamia, Akkad as heir of Kish, brought about a series of destructive wars. Some of them, under the first ruler of Akkad, Sargon (2335-2279), were intended to conquer the Sumerian south and gave origin to the first regional state that included the entire Lower Mesopotamian river region. After that, more wars were intended to acquire control of the trade network, and were directed against Susa (Iranian network), against Magan (Gulf network), against Mari and Ebla, both of them destroyed by Naram-Sin (2254-2218), the most important king of Akkad. The celebrative inscriptions and monuments of the Akkadian kings were the expression of a new idea of ‘‘heroic’’ kingship and of enlarged territorial control. The deification of Naram-Sin clearly contrasted to the old Sumerian ideology of the city leader as administrative representative of the god. Later legends and epic compositions, while reserving to Sargon the image of the pious and successful king, blamed Naram-Sin for hubris and disaster.
The Akkad dynasty did not survive for long, and the decline started after Naram-Sin. A major factor was the pressure of the outer nomads, both from the mountaineers (Gutians and Lullubi in the Zagros Mountains) and the steppe tribes (Martu, better known as Amorites). Archaeology also gives a picture of decline of the splendid civilizations of the Early Bronze age, in Anatolia, in the Levant, in Iran, and the Gulf area. We get the impression that the ‘‘second urbanization’’ reached its peak around 2300, and then started a fast decline. The massive intrusions of the Gutians (about 2200) and the Martu (about 2000) in middle and lower Mesopotamia were part of this scenario. In Egypt, the fragmented socio-political order in the first ‘‘Intermediate Period’’ was roughly contemporary. In the Levant, the so-called ‘‘Intermediate (Early/Middle Bronze) Period’’ showed an archaeological picture dominated by pastoralism and decline of urban life. As usual, the periphery was more decisively affected, while the main core of urbanization, in lower Mesopotamia, could better resist the troubles.
The last century of the third millennium, when the crisis was already well advanced in the peripheral areas, was dominated in the river valleys by the third dynasty of
Ur (2112-2004), which represented the most efficient and stable state organization that Mesopotamia ever experienced, in earlier or later times. In a short period, under Ur-Nammu, Shulgi, Amar-Sin, and Shu-Sin, the Ur kings were able to revitalize Sumerian culture and religious ideology, and to extend the model of the temple-city to a wider region in which the former city-states were transformed into provinces. Instead of celebrative monuments, they left temple buildings, including the famous temple-towers or ziggurats, irrigation canals, and defensive walls. They unified prices and measures inside their kingdom, and provided it with a law-code and a land-register. They produced a uniform and efficient bureaucratic record of the economy with the most detailed accounting procedures: crop estimates before harvest, estimates of growth for herds and flocks, balanced accounts for merchants, all based on administrative conventions and fixed rates. Cultic literature and royal hymns flourished during the ‘‘Neo-Sumerian renaissance,’’ while cities and countryside in the core of the empire flourished in peace and order.
However, the effect of external troubles could not be avoided forever. In spite of various expeditions carried on in Subartu (Upper Mesopotamia) and on the Zagros piedmont, and in spite of the ‘‘Martu-wall’’ erected from Tigris to Euphrates in order to stop, or at least to check, the infiltration of the West Semitic nomads, the Martu finally succeeded in penetrating in substantial number into Mesopotamia, possibly driven out of their homeland in the Syrian steppe by an unfavorable climatic change. The Martu conquered and ravaged all the provinces, and Ur was left without revenues and protection. The capital city was finally besieged and conquered by the Elamites. The name of the last Ur king, Ibbi-Sin, remained in the handbooks of Babylonian omens as a symbol of disaster.
