The employment of the title of patesi, and the total absence of that of "king" at this time, suggests that Lagash had not succeeded in establishing her independence, and still owed allegiance to some alien dynasty. It is in accordance with this view that the dates inscribed upon the commercial tablets do not refer to events of a military character. We may conclude that, at any rate until the reign of Gudea, Lagash and her rulers were not concerned to enforce their authority over other cities, nor to defend their own border from attack. The existence of a more powerful city, claiming the hegemony in Babylonia, would account for the absence of military enterprise reflected in the date-formulæ and in the foundation-records of the time. For such a city, while guaranteeing the integrity of each of her tributary states, would have resented the inauguration of an ambitious policy by any one of them. On the other hand, the purely local character of the events commemorated in the date-formulæ is no less significant. These are without exception drawn from the local history of Lagash, and betray no evidence of the authority exercised by a foreign suzerain. It is therefore probable that during the greater part of this period Lagash enjoyed a considerable measure of autonomy, and that such bonds as may have united her to any central administration were far less tightly drawn than at the time of Shar-Gani-sharri and Narâm-Sin. Like Lagash, her old rival Umma seems to have survived as a patesiate under the later Semitic rulers in the north, and it is probably to this time that we may assign Galu-Babbar, the patesi of that city, three of whose votive cones are preserved in the British Museum.[14] During the earlier part of this period Lagash presents the picture of a compact and peaceful state, content to develop her own resources. A considerable increase of power is noticeable in the reign of Gudea, the most famous ruler of the period, who, though still retaining the title of patesi, must be regarded as practically an independent sovereign, since he was strong enough to undertake a successful campaign in Elam, and imported his building materials from Arabia and the Syrian coast.
