 The Assyrian King List records that Shamshi-Adad I, “went away to Babylonia in the time of Naram-Sin” while Naram-Sin of Eshnunna had been attacking Ekallatum.Shamshi-Adad I had not returned until he had taken Ekallatum, after which he had paused for three years and then had overthrown Erishum II.The Mari Eponym Chronicle, which resumes the listing until the seizure of Ekallatum by Shamshi-Adad I, provides no clue as to when the succession of Erishum II had taken place.
