The late chronicler, who records these events, tells us that Ulam-Buriash was the brother of Kashtiliash, the Kassite, whom we may probably identify with the third ruler of the Kassite Dynasty of Babylon. There Gandash, the founder of the dynasty, had been succeeded by his son Agum, but after the hitter's reign of twenty-two years Kashtiliash, a rival Kassite, had secured the throne.[8] He evidently came of a powerful Kassite tribe, for it was his brother, Ulam-Buriash, who conquered the Country of the Sea. We have recovered a memorial of the latter's reign in a knob or mace-head of diorite. which was found during the excavations at Babylon.[9] On it he terms himself King of the Sea-Country, and we learn from it, too, that he and his brother were the sons of Burna-Burariash, or Burna-Buriash, who may have remained behind as a local Kassite chieftain in Elam, while his sons between them secured the control of Babylonia. After a certain interval the Sea-Country must have revolted from Ulam-Buriash, for its reconquest was undertaken by Agum, a younger son of Kashtiliash, who is recorded to have captured the city of Dûr-Enlil and to have destroyed E-malga-uruna, the local temple of Enlil.[10] The eldest son of Kashtiliash had meanwhile succeeded his father on the throne of Babylon, and, if Agum established his rule in the Sea-Country, we again have the spectacle of two brothers, in the next generation of this Kassite family, dividing the control of Babylonia between them. But as the chronicler does not record that Agum, like his uncle Ulam-Buriash, exercised dominion over the Sea-Country as a whole, he may have secured little more than a local success. The throne of Babylon then passed to the second son of Kashtiliash, Abi-rattash, and it was possibly by him, or by one of his successors, that the whole country was once more united under Babylon's rule.
