seems to have had a peaceful reign. Despite not being able to regain northern Babylonia from Assyria, no further territory was lost, Elam did not threaten, and the Late Bronze Age collapse now affecting the Levant, Canaan, Egypt, the Caucasus, Anatolia, Mediterranean, North Africa, northern Iran and Balkans seemed (initially) to have little impact on Babylonia (or indeed Assyria and Elam). War resumed under subsequent kings such as Marduk-apla-iddina I (1171–1159 BC) and Zababa-shuma-iddin (1158 BC). The long reigning Assyrian king Ashur-dan I (1179–1133 BC) resumed expansionist policies and conquered further parts of northern Babylonia from both kings, and the Elamite ruler Shutruk-Nakhunte eventually conquered most of eastern Babylonia. Enlil-nadin-ahhe (1157–1155 BC) was finally overthrown and the Kassite dynasty ended after Ashur-dan I conquered yet more of northern and central Babylonia, and the equally powerful Shutruk-Nahhunte pushed deep into the heart of Babylonia itself, sacking the city and slaying the king. Poetical works have been found lamenting this disaster. Despite the loss of territory, general military weakness, and evident reduction in literacy and culture, the Kassite dynasty was the longest-lived dynasty of Babylon, lasting until 1155 BC, when Babylon was conquered by Shutruk-Nakhunte of Elam, and reconquered a few years later by the Nebuchadnezzar I, part of the larger Late Bronze Age collapse. Early Iron Age – Native rule, second dynasty of Isin, 1155–1026 BC The Elamites did not remain in control of Babylonia long, instead entering into an ultimately unsuccessful war with Assyria, allowing Marduk-kabit-ahheshu (1155–1139 BC) to establish the Dynasty IV of Babylon, from Isin, with the very first native Akkadian-speaking south Mesopotamian dynasty to rule Babylonia, with Marduk-kabit-ahheshu becoming only the second native Mesopotamian to sit on the throne of Babylon, after the Assyrian king Tukulti-Ninurta I. His dynasty was to remain in power for some 125 years. The new king successfully drove out the Elamites and prevented any possible Kassite revival. Later in his reign he went to war with Assyria, and had some initial success, briefly capturing the south Assyrian city of Ekallatum before ultimately suffering defeat at the hands of Ashur-Dan I. Itti-Marduk-balatu succeeded his father in 1138 BC, and successfully repelled Elamite attacks on Babylonia during his 8-year reign. He too made attempts to attack Assyria, but also met with failure at the hands of the still reigning Ashur-Dan I. Ninurta-nadin-shumi took the throne in 1137 BC, and also attempted an invasion of
