 A certain Ikūn-pî-Ištar is recorded as having ruled for 6 months or a year, between the reigns of Erra-imittī and Enlil-bani according to two variant copies of a chronicle.Another chronicle which might have shed further light on his origins is too broken to translate.Hegemony over Nippur was fleeting, with control of the city passing back and forth between Isin and Larsa several times.
