Ibbi-Sin bitterly lambasted Ishbi-Erra as “not of Sumerian seed” in his letter to Puzur-Šulgi and opined that: “Enlil has stirred up the Amorites out of their land, and they will strike the Elamites and capture Ishbi-Erra.” Curiously, Puzur-Šulgi seems to have originally been one of Ishbi-Erra's own messengers and indicates the extent to which loyalties were in flux during the waning years of the Ur III regime. While there was no outright conflict, Ishbi-Erra continued to extend his influence as Ibbi-Sin's steadily declined over the next 12 years or so, until Ur was finally conquered by Kindattu of Elam.[6]
