Strengthening this connection is that Nebuchadnezzar II is attested very early during his father's reign, from 626/625 to 617 BC, as high priest of the Eanna temple in Uruk, where he is often attested under the nickname "Kudurru". Nebuchadnezzar must have been made high priest at a very young age, considering that his year of death, 562 BC, is 64 years after 626 BC. The original Kudurru's second son, Nabu-shumu-ukin, also appears to be attested as a prominent general under Nabopolassar, and the name was also used by Nebuchadnezzar II for one of his sons, possibly honoring his dead uncle.

Given that Nebuchadnezzar is referred to as the father of Belshazzar in the Book of Daniel, it is probable that this portrayal of Nebuchadnezzar, especially the story of his madness, was actually based on Belshazzar's real father, Nabonidus, the last king of the Neo-Babylonian Empire ((r. undefined – undefined)556–539 BC). Separate Jewish and Hellenistic traditions exist concerning Nabonidus having been mad, and it is likely that this madness was simply reattributed to Nebuchadnezzar in the Book of Daniel through conflation. Some later traditions conflated Nebuchadnezzar with other rulers as well, such as the Assyrian Ashurbanipal ((r. undefined

Content:  Nebuchadnezzar II (Babylonian cuneiform: Nabû-kudurri-uṣur, meaning "Nabu, watch over my heir"; Biblical Hebrew:  Nəḇūḵaḏneʾṣṣar) also spelled Nebuchadrezzar II, was the second king of the Neo-Babylonian Empire, ruling from the death of his father Nabopolassar in 605 BC to his own death in 562 BC. Historically known as Nebuchadnezzar the Great, he is typically regarded as the empire's greatest king. Nebuchadnezzar remains famous for his military campaigns in the Levant, for his construction projects in his capital, Babylon, and for the important part he played in Jewish history. Ruling for 43 years, Nebuchadnezzar was the longest-reigning king of the Chaldean dynasty.

Possibly named after his grandfather of the same name, or after Nebuchadnezzar I ((r. undefined – undefined)c. undefined 1125–1104 BC), one of Babylon's greatest ancient warrior-kings, Nebuchadnezzar II already secured renown for himself during his father's reign, leading armies in the Medo-Babylonian war against the Assyrian Empire. At the Battle of Carchemish in 605 BC, Nebuchadnezzar inflicted a crushing defeat on an Egyptian army led by Pharaoh Necho II, and ensured that the Neo-Babylonian Empire would succeed the Neo-Assyrian Empire as the dominant power

Nebuchadnezzar II's name, Nabû-kudurri-uṣur, was identical to the name of his distant predecessor, Nebuchadnezzar I ((r. undefined – undefined)c. undefined 1125–1104 BC), who ruled more than five centuries before Nebuchadnezzar II's time. Like Nebuchadnezzar II, Nebuchadnezzar I was a renowned warrior-king, who appeared in a time of political upheaval and defeated the forces of Babylon's enemies, in Nebuchadnezzar I's case the Elamites.

Most of the sons, with the exceptions of Marduk-nadin-ahi and Eanna-sharra-usur, are attested very late in their father's reign. It is possible that they might have been the product of a second marriage and that they could have been born relatively late in Nebuchadnezzar's reign, possibly after his known daughters. The known sons of Nebuchadnezzar are: Three of Nebuchadnezzar's daughters are known by name: It is possible that one of Nebuchadnezzar's daughters married the high official Nabonidus. Marriage to a daughter of Nebuchadnezzar could explain how Nabonidus could became king, and also explain

Though there is no evidence that Nabopolassar named his son after Nebuchadnezzar I, Nabopolassar was knowledgeable in history and actively worked to connect his rule to the rule of the Akkadian Empire, which preceded him by nearly two thousand years. The significance of his son and heir bearing the name of one of Babylon's greatest kings would not have been lost on Nabopolassar. If Jursa's theory concerning Nabopolassar's origin is correct, it is alternatively possible that Nebuchadnezzar II was named after his grandfather of the same name, as the Babylonians employed patronymics, rather than after the previous king.
Title: Nebuchadnezzar II
Content:  Nebuchadnezzar was the eldest son of Nabopolassar ((r. undefined – undefined)626–605 BC), the founder of the Neo-Babylonian Empire. This is confirmed by Nabopolassar's inscriptions, which explicitly name Nebuchadnezzar as his "eldest son", as well as inscriptions from Nebuchadnezzar's reign, which refer to him as the "first" or "chief son" of Nabopolassar, and as Nabopolassar's "true" or "legitimate heir". The Neo-Babylonian Empire was founded through Nabopolassar's rebellion, and later war, against the Neo-Assyrian Empire, which liberated Babylonia after nearly a century of Assyrian control. The war resulted in the complete destruction of Assyria, and the Neo-Babylonian Empire, which rose in its place, was powerful, but hastily built and politically unstable. As Nabopolassar never

His reign was marred with intrigues and he only ruled for two years before being murdered and usurped by his brother-in-law, Neriglissar. Later Babylonian sources mostly speak ill of his reign. Amel-Marduk is first attested, notably as crown prince, in a document 566 BC. Given that Amel-Marduk had an older brother in Marduk-nadin-ahi, alive as late as 563 BC, why he was named crown prince is not clear. ; Marduk-shum-usur (Akkadian: Marduk-šum-uṣur or Marduk-šuma-uṣur) – named as a "royal prince" in documents from Nebuchadnezzar's 564 BC and 562 BC years, recording payments by his scribe to the
