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.
