Iddin-Dagān then succeeded Šu-ilišu. Šu-ilišu is best known for his retrieval of the cultic idol of Nanna from the Elamites and its return to the city-state Ur. Šu-ilišu's inscriptions gave him the titles: “Mighty Man” — “King of Ur” — “God of His Nation” — “Beloved of the gods: Anu, Enlil, and Nanna” — “King of the Land of Sumer and Akkad” — “Beloved of the god Enlil and the goddess Ninisina” — “Lord of his Land”, but not “King of Isin” (a title which was not claimed by a ruler of this city-state until the later reign of Išme-Dagān.) Šu-ilišu did, however; rebuild the walls of his capital city: Isin. He was a great benefactor of the city-state Ur (beginning the restoration which was to continue through his successors: Iddin-Dagān and Išme-Dagan.) Šu-ilišu built a monumental gateway and recovered an idol representing Ur's patron deity (Nanna, god of the moon) which had been expropriated by the Elamites when they sacked the city-state, but; whether he obtained it either through diplomacy or conflict is unknown. An inscription tells of the city-state's resettlement: “He established for him when he established in Ur the people scattered as far as Anšan in their abode.” The "Lamentation over the Destruction of Ur" was composed around this time to explain the catastrophe, to call for its reconstruction and to protect the restorers from the curses attached to the ruins of the é.dub.lá.maḫ.  Šu-ilišu commemorated: the fashioning of a great emblem for Nanna, an exalted throne for An, a dais for Ninisin, a magur-boat for Ninurta, and a dais for Ningal in year names for Šu-ilišu's reign. An adab (or hymn) to Nergal was composed in honor of Šu-ilišu, together with an adab of An and perhaps a 3rd addressed to himself.
