Some time after, Lagash succeeded in asserting her independence, and many of her subsequent rulers style themselves “kings.” The First Dynasty of Lagash which was seemingly founded by Ur-Ninâ established themselves securely for some considerable time, but the reign of Urukagina saw the end of the dynasty, and the capture and sack of the city by Lugal-zaggisi, a ruler of the neighbouring city of Umma. The limits of Lugal-zaggisi’s empire included Ur, Erech, Larsa and Nippur, and he was undoubtedly one of the most powerful rulers of his day. Other pre-Sargonic kings whose power was specifically associated with Erech and Ur, were Lugal-kigub-nidudu and Lugal-kisalsi, but the extent of their sway cannot be estimated with any degree of certainty. In the time immediately preceding the establishment of the empire of Shar-Gâni-sharri and Narâm-Sin, the rallying point of the Semitic forces of Akkad seems to have been the city of Kish, the conquests of whose three kings Sharru-Gi Manishtusu and Urumush prepared the way for their successors at Agade. Thus both Manishtusu and Urumush seem to have extended their power southward into the land of Sumer, while both these kings warred successfully against Elam. The empire of Shar-Gâni-sharri and Narâm-Sin was however destined to entirely eclipse that of their forerunners, for it not only embraced Mesopotamia north and south, but also Syria and Palestine, and was in fact the first Babylonian empire worthy of the name. Meanwhile the power of the Sumerians in the south had received a temporary check, and the patesis of Lagash, and other Sumerian centres at the time, clearly ruled on sufferance and not on the strength of rights which they were prepared to assert successfully in the battle-field. But on the accession of Gudea about 2450 B.C., the momentarily smoking flame of Sumerian influence in Babylonia was kindled anew, and a strong anti-Semitic wave set in. This wave does not seem to have been characterized by a series of wars or battles, for the records of Gudea, the most powerful ruler among the later patesis of Lagash, seldom refer to anything in the nature of military achievements, but the extensiveness of his building operations testifies to the abundance of resources at his command, while the names of the countries which he laid under contribution for building-materials conclusively prove that the influence exercised by Lagash during the reign of Gudea was considerable. The list of the places from which he derived wood and stone includes the mountains in Arabia and on the Syrian coast, while he obtained copper from the mines in the Elamite territory east of the Tigris.
