We have already seen that, in spite of the increase in the power of Lagash during the reign of Eannatum, the city of Umma had not been incorporated in its dominion, but had succeeded in maintaining an attitude of semi-independence. This is apparent from the terms of the treaty, by which the men of Umma undertook not to invade the territory of Lagash; and, although they paid a heavy tribute in corn to Eannatum, we may assume that they were ready to seize any opportunity that might present itself of repudiating the suzerainty of Lagash. Such an opportunity they may have seen in the death of their conqueror Eannatum, for after the accession of his brother we find them repeating the same tactics they had employed during the preceding reign under the leadership of their patesi, Ush. Enakalli, with whom Eannatum had drawn up his treaty, had been succeeded on the throne by Urlumma. In his cone-inscription Entemena gives no indication as to whether there was any interval between the reign of Enakalli and that of Urlumma. But from a small tablet of lapis-lazuli in the "Collection de Clercq," we gather that the latter was Enakalli's son, and, therefore, probably his direct successor upon the throne.[2] The little tablet was employed as a foundation-memorial, and a short inscription upon it records the building of a temple to the god Enkigal by Urlumma, who describes himself as the son of Enakalli. Each ruler bears the title of "king" in the inscription, and, although the reading of the sign following the title is uncertain, there is little doubt that we should identify the Urlumma and Enakalli of the tablet with the two patesis of Umma who are known to have borne these names. Urlumma did not maintain his father's policy, but, following Ush's example, marshalled his army and made a sudden descent upon the territory of Lagash. His raid appears to have been attended with even greater violence than that of his predecessor. Ush had contented himself with merely removing the stele of delimitation set up by Mesilim, but Urlumma broke that of Eannatum in pieces by casting it into the fire, and we may assume that he treated Mesilim's stele in the same way.[3] The shrines, or chapels, which Eannatum had built upon the frontier and had dedicated to the gods whom he had invoked to guard the treaty, were now levelled to the ground. By such acts Urlumma sought to blot out all trace of the humiliating conditions imposed in earlier years upon his city, and, crossing the frontier-ditch of Ningirsu, he raided and plundered the rich plains which it had always been the ambition of Umma to possess.
