6th-century BC regents

Belshazzar (Babylonian cuneiform: 96x96pxBēl-šar-uṣur, meaning "Bel, protect the king"; Bēlšaʾṣṣar) was the son and crown prince of Nabonidus (), the last king of the Neo-Babylonian Empire. Through his mother, he might have been a grandson of Nebuchadnezzar II (), though this is not certain and the claims to kinship with Nebuchadnezzar may have originated from royal propaganda.
