Adad-shuma-usur

Adad-šuma-uṣur, inscribed dIM-MU-ŠEŠ, meaning "O Adad, protect the name!," and dated very tentatively c. 1217-1187 BC, was the 32nd king of the 3rd or Kassite dynasty of Babylon and the country contemporarily known as Karduniaš. His name was wholly Babylonian and not uncommon, as for example the later Assyrian King Esarhaddon had a personal exorcist, or ašipu, with the same name who was unlikely to have been related. He is best known for his rude letter to Aššur-nirari III, the most complete part of which is quoted below, and was enthroned following a revolt in the south of Mesopotamia when the north was still occupied by the forces of Assyria. He may not have assumed authority throughout the country until around the 25th year of his 30-year reign, although the exact sequence of events and chronology remains disputed.
