Agum III in Wikipedia

Agum III was a Kassite king of Babylon ca. mid 14th century BC. Little is known about the king, with the only Babylonian reference to him from an expedition he led against "the Sealand" ca. 1465 BC[1]. He reputedly conquered the Sealand city of Dur-Ea, which left him in control of all of Babylonia.[2] He was succeeded by his son, Ulamburaish[citation needed], who undertook further campaigns against the Sealands.[3].
