As crown prince/commander, Nebuchadnezzar led Babylonian forces to defeat Egypt and its allies at Carchemish, decisively shifting control of Syria-Palestine toward Babylonia and ending Egypt’s bid for dominance in the region.
After Carchemish, Babylonian forces pursued and defeated remnants of the Egyptian army near Hamath, consolidating Babylonian control in the Levant and reducing Egypt’s ability to reassert itself there.
Nebuchadnezzar’s formal coronation followed soon after his accession, reinforcing dynastic legitimacy at the start of an unusually long and stable reign.
Nebuchadnezzar attempted to invade Egypt but suffered heavy losses in fighting near the eastern Egyptian frontier (often identified with Migdol), temporarily slowing Babylonian operations and prompting force rebuilding.
Nebuchadnezzar’s building program included substantial new or strengthened city defenses. Inscribed foundation cylinders—buried as part of construction practice—record works such as an outer city wall built with baked brick and bitumen.
Babylon besieged Jerusalem; the city surrendered, King Jehoiachin (Jeconiah) was taken captive, and Zedekiah was installed as a Babylonian client king. This event is attested in the Babylonian Chronicles and is central to the chronology of the Babylonian Exile.
A major Babylonian Chronicle tablet (BM 21946; ABC 5), describing early years of Nebuchadnezzar II including western campaigns and Jerusalem’s capture, was written down within the reign and later preserved in the British Museum collection.
Nebuchadnezzar’s forces began a renewed siege of Jerusalem during Zedekiah’s reign after rebellion against Babylon, a campaign that culminated in the kingdom’s collapse.
Nebuchadnezzar undertook a prolonged siege of the Phoenician city of Tyre, remembered in later sources as lasting roughly 13 years; it reflects Babylon’s effort to control key coastal trade centers and Levantine politics.
Jerusalem was captured and the First Temple (Solomon’s Temple) was destroyed in the final phase of the Babylonian campaign. Scholarly chronologies commonly place the fall and destruction in 587/586 BCE (debated by one year depending on regnal-year counting).
Nebuchadnezzar ordered the construction/monumental rebuilding of the Ishtar Gate and the Processional Way using blue-glazed bricks and animal reliefs associated with key deities, creating a ceremonial entrance that helped define Babylon’s imperial image (often dated to the mid-reign, c. 575 BCE).
The long Tyrian siege concluded after many years of pressure, illustrating both Babylon’s reach and the difficulty of subduing major maritime powers protected by fortifications and seaborne supply.
Nebuchadnezzar died in Babylon in early October 562 BCE; administrative tablets align his final dated records with the first dated records of his successor, Amel-Marduk, marking the transition of power at court.
Nebuchadnezzar II succeeded his father Nabopolassar and began a 43-year reign that marked the height of Neo-Babylonian imperial power and an extensive program of royal building at Babylon.
