During the six years that immediately followed the successful, forty-three-year-long reign of Nebuchadnezzar II (605–562), four kings ascended the Babylonian throne in quick succession. Nebuchadnezzar's son Amēl-Marduk (561–560) reigned for just two years before he was murdered and replaced by his brother-in-law Neriglissar (559–556), who died after ruling over Babylonia for three years and eight months. After only two or three months on the throne, Neriglissar's young and inexperienced son Lâbâši-Marduk (556) was removed during a coup d'état and replaced by Nabonidus (555–539), the man who would be Babylon's last native king. Seventeen years later, in 539, when Cyrus II took control of Babylon and its territorial holdings, the once-great Babylonian Empire founded by Nabopolassar (625–605) came to an abrupt end.
