After Sennacherib had died, Babylon and the surrounding territories were so appalled over the fact that he had sacked Babylon, that his successors found it very difficult to establish any sort of peace. A major rebellion broke out and lasted for four years (652-648 BC) during the reign of Shamash-shuma-ukin, an Assyrian king who had been placed to rule in what was left of Babylon. Shamash-shuma-ukin was also the brother of the new Assyrian monarch Ashurbanipal (668-627 BC). When the Babylonians, the Elamites and all their Arab allies came against Ashurbanipal, they were defeated.
