King Nabonidus of Babylon: The Scholar-King Who Lost an Empire
King Nabonidus (reigned c. 556–539 BCE) was the last ruler of the Neo-Babylonian Empire, a kingdom that had once flourished under Nebuchadnezzar II but ultimately fell to Cyrus the Great of Persia. Nabonidus was an unconventional king—a ruler more interested in archaeology, religious reforms, and ancient traditions than in war and governance. His long absence from Babylon, religious conflicts, and failure to resist the Persian invasion led to the fall of Babylon and the end of Mesopotamian independence.
Nabonidus came to power in 556 BCE, after the assassination of Labashi-Marduk, the young and short-lived successor of King Neriglissar. Unlike his predecessors, Nabonidus was not of royal lineage and may have been an official or general before ascending the throne. He quickly established himself as a deeply religious king, but his devotion to the moon god Sin over the traditional Babylonian god Marduk created widespread unrest among the powerful priesthood of Babylon.
One of the most controversial decisions of his reign was his self-imposed exile in Tayma (modern-day Saudi Arabia), a city deep in the Arabian desert. Around 552 BCE, Nabonidus mysteriously left Babylon and spent nearly a decade in Tayma, focusing on religious practices, leaving his son Belshazzar as regent in Babylon. This absence weakened his rule and alienated the Babylonian elite, who saw him as neglecting his royal duties.
Meanwhile, in Persia, Cyrus the Great was rapidly expanding his empire. By 540 BCE, the Persian army had already conquered much of the Near East, and Babylon was one of the last remaining independent powers. Despite growing threats, Nabonidus failed to unite his people or prepare for war.
In 539 BCE, Cyrus the Great launched his campaign against Babylon. The decisive Battle of Opis saw the Babylonian army crushed by Persian forces, and soon after, the Persians marched unopposed into Babylon. According to historical accounts, the city was taken without resistance, possibly because of internal betrayal or lack of support for Nabonidus. The famous "Cyrus Cylinder" describes how the Babylonians welcomed Cyrus as a liberator.
Nabonidus was captured, and his fate remains uncertain. Some sources claim he was exiled to Carmania (modern-day Iran), while others suggest he lived the rest of his days under Persian rule. With his defeat, the Neo-Babylonian Empire came to an end, and Mesopotamia became a province of the Achaemenid Persian Empire.
Despite his failures as a ruler, Nabonidus left behind an important legacy as one of the first archaeologists in history. He excavated and restored ancient temples, studied inscriptions of past civilizations, and preserved the history of Mesopotamia. However, his religious reforms, long absences, and strategic failures overshadowed his intellectual achievements, making him the king who lost Babylon.
