Everything that is known about him is through the Agum-Kakrime Inscription, an Akkadian text written in the neo-Assyrian cuneiform script but in very short lines in imitation of an antiquarian style. It is extant in two copies, which describe the King's recovery of the cultic Statue of Marduk from the land of Ḫana ( ḫa-ni-i), pilfered by the Hittites during their sack of Babylon, and its restoration in the newly refurbished temple of Ésagila. In it, Agum portrays himself as the legitimate ruler and caring shepherd of both the Kassites and the Akkadians. He asserts his suzerainty over Padan and Alman and also the Guteans, a foolish people, groups variously located in regions of the Zagros mountains.
