the Assyrian king Puzur-Ashur III, and had a largely uneventful reign, as did his successor Kashtiliash III. The Sealand Dynasty of southern Mesopotamia remained independent of Babylonia and in native Akkadian-speaking hands. Ulamburiash managed to attack it and conquered parts of the land from Ea-gamil, a king with a distinctly Sumerian name, around 1450 BC, whereupon Ea-Gamil fled to his allies in Elam. The Sealand Dynasty region still remained independent, and the Kassite king seems to have been unable to finally conquer it. Ulamburiash began making treaties with ancient Egypt, which then was ruling southern Canaan, and Assyria to the north. Agum III also campaigned against the Sealand Dynasty, finally wholly conquering the far south of Mesopotamia for Babylon, destroying its capital Dur-Enlil in the process. From there Agum III extended farther south still, invading what was many centuries later to be called the Arabian Peninsula or Arabia, and conquering the pre-Arab state of Dilmun (in modern Bahrain). Karaindash built a bas-relief temple in Uruk and Kurigalzu I (1415–1390 BC) built a new capital Dur-Kurigalzu named after himself, transferring administrative rule from Babylon. Both of these kings continued to struggle unsuccessfully against the Sealand Dynasty. Karaindash also strengthened diplomatic ties with the Assyrian king Ashur-bel-nisheshu and the Egyptian Pharaoh Thutmose III and protected Babylonian borders with Elam. Kadašman-Ḫarbe I succeeded Karaindash, and briefly invaded Elam before being eventually defeated and ejected by its king Tepti Ahar. He then had to contend with the Suteans, ancient Semitic-speaking peoples from the southeastern Levant who invaded Babylonia and sacked Uruk. He describes having "annihilated their extensive forces", then constructed fortresses in a mountain region called Ḫiḫi, in the desert to the west (modern Syria) as security outposts, and "he dug wells and settled people on fertile lands, to strengthen the guard". Kurigalzu I succeeded the throne, and soon came into conflict with Elam, to the east. When Ḫur-batila, the successor of Tepti Ahar took the throne of Elam, he began raiding the Babylonia, taunting Kurigalzu to do battle with him at Dūr-Šulgi. Kurigalzu launched a campaign which resulted in the abject defeat and capture of Ḫur-batila, who appears in no other inscriptions. He went on to conquer the eastern lands of Elam. This took his army to the Elamite capital, the city of Susa, which was sacked. After this a puppet ruler was placed on the Elamite throne, subject to Babylonia. Kurigalzu I
