 Gungunum had wrestled Ur from Isin's control by his 10th year and it is possible this was the cause of Lipit-Ištar's overthrow.Indeed, Ur-Ninurta made a dedicatory gift to the temple of Ningal in Ur during the 9th year of Gungunum.However, Ur-Ninurta continued to mention Ur in his titles ("herdsman of Ur") as did his successors in Isin.
