 He was succeeded by his son, who took the name Nebuchadnezzar II, after the unrelated 12th century BCE native Akkadian-Babylonian king Nebuchadnezzar I, indicating the extent to which the migrant Chaldeans had become infused with native Mesopotamian culture.Nebuchadnezzar II and his allies may well have been forced to deal with remnants of Assyrian resistance based in and around Dur-Katlimmu, as Assyrian imperial records continue to be dated in this region between 604 and 599 BCE.In addition, the Egyptians remained in the region, possibly in an attempt to aid their former Assyrian masters and to carve out an empire of their own.
