Eighth King of the fourth dynasty of Babylon (Isin dynasty II), that ruled 22 years, according to the actual list, after defeating Marduk-shapik-zeri-mati, his predecessor on the throne. The synchronous Chronicle considers him son of Esagil-shaduni, a "son of no one"; for its part, the Royal Chronicle makes it son of Itti-Marduk-balatu, Aramaic and usurper. Adad-apla-iddina in one of his inscriptions are considered son of Harru-ukin. Either way, this King maintained excellent relations with Assyria, whose King Ashur-bel-kala, who was in fact the throne, became his son-in-law. Babylon could do front during his reign the invading people of the sutu, which devastated vast regions. Adad-apla-iddina was a friendly Monarch with the religious past, expanding or rebuilding temples (of Zababa in Kish, sin in Ur). He/She was succeeded by Marduk-ahhe-eriba.
