Kazallu (Puzur-Numushda, later renamed Puzur-Šulgi). These are literary letters, copied in antiquity as scribal exercises and their authenticity is unknown.
Charged with acquiring grain in Isin and Kazallu, Ishbi-Erra complained that he could not ship the 72,000

Nippur.
[CBS 2272, letter from Išbi-erra to Ibbi-Sin.] Although Ibbi-Sin baulked at promoting him, Ishbi-Erra apparently succeeded in wrestling control over Isin by Ibbi-Sin's 8th year, when he began assigning his own regnal year-names, and thereafter an uneasy chill descended on their relationship.
Ibbi-Sin bitterly lambasted Ishbi-Erra as being "not of Sumerian seed" in his letter to Puzur-Šulgi and opined that: "

Elamites and capture Ishbi-Erra." Puzur-Šulgi seems to have originally been one of Ishbi-Erra's own messengers and indicated the extent to which loyalties were in flux during the waning years of the regime of the third dynasty of Ur. 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.
Ishbi-Erra went on to win decisive victories against the Amorites in his 8th year and the Elamites in his 16th year. Some years later, Ishbi-Erra ousted the Elamite garrison from
Ur, thereby asserting suzerainty over

He founded fortresses and installed city walls, but only one royal inscription is extant.[IM 58336, Construction of a great lyre for Enlil.]
Various hymns to Ishbi-Erra, king of Isin, are known.
