Nabopolassar

Nabopolassar (, meaning "Nabu, protect the son") was the founder and first king of the Neo-Babylonian Empire, ruling from his coronation as king of Babylon in 626 BC to his death in 605 BC. Though initially only aimed at restoring and securing the independence of Babylonia, Nabopolassar's uprising against the Neo-Assyrian Empire, which had ruled Babylonia for more than a century, eventually led to the complete destruction of the Assyrian Empire and the rise of the Neo-Babylonian Empire in its place.

Of unclear, possibly Chaldean, origin and potentially connected to a powerful political family in the southern city of Uruk, Nabopolassar revolted against the Neo-Assyrian king Sinsharishkun at an opportune moment when Babylonia was already plagued by political instability. Though the advantage shifted back and forth dramatically several times, Nabopolassar managed to decisively push the Assyrians out of Babylonia after nearly ten years of fighting. Subsequent campaigns were intended to hinder the possibility of an Assyrian campaign directed at Babylonia through securing the border, but the intervention of the eastern Median Empire under Cyaxares in Nabopolassar's favor shifted the goals and the possibilities of the war.
