Ashduni-erim does not refer to his enemy by name, but it is to be noted that the hostile territory lay within a day's march of Kish, a description that surely points to Babylon. The eight years of conflict fit in admirably with the suggestion, for we know that it was in Sumu-abum's tenth year, exactly eight years after his occupation of Kibalbarru, that his suzerainty was acknowledged in Kish. Sumu-abum named that year of his reign after his dedication of a crown to the god Anu of Kish,[54] and we may conjecture that Ashduni-erim, weakened by the long conflict which he describes, came to terms with his stronger neighbour and accepted the position of a vassal. Having given guarantees for his fidelity, he would have received Sumu-abum in Kish, where the latter as the suzerain of the city performed the dedication he commemorated in his date-formula for that year. This would fully explain the guarded terms in which Ashduni-erim refers to the enemy in his inscription, the rebuilding of the city-wall having, on this supposition, been undertaken with Babylon's consent.[55] [Illustration: HAMMURABI RECEIVING HIS LAWS FROM THE SUN GOD. After Délég. en Perse, Mém. IV, pl. 3] That Kish was accorded the position of a vassal state is certain, for, among contract-tablets recovered from the city, several were drawn up in the reign of Mananâ, who was Sumu-abum's vassal. In these documents the oath is taken in Mananâ's name, but they are dated by the formula for Sumu-abum's thirteenth year, commemorating his capture of Kazallu. The importance of the latter event may be held to explain the use of the suzerain's own formula, for other documents in Mananâ's reign are dated by local events, proving that at Kish, as at Sippar, a vassal city of Babylon was allowed the privilege of retaining its own system of time-reckoning. If we are right in regarding Ashduni-erim as Sumu-abum's contemporary, it is clear that he must have been succeeded by Mananâ within three years of his capitulation to Babylon. During the next few years the throne of Kish was occupied by at least three rulers in quick succession, Sumu-ditana, Iawium, and Khalium,[56] for we know that by the thirteenth year of Sumu-la-ilum, who succeeded Sumu-abum on the throne of Babylon, the city of Kish had revolted and had been finally annexed.
