FALL OF BABYLON
The fall of Babylon was the decisive event that marked the total defeat of the Neo-Babylonian Empire to the Achaemenid Persian Empire in 539 BCE.
Nabonidus, the final Babylonian king and son of the Assyrian priestess Adad-guppi,[4] ascended to the throne in 556 BCE, after overthrowing his predecessor Labashi-Marduk. For long periods, he would entrust rule to his son Belshazzar, who was a capable soldier but a poor politician. As a result, he was somewhat unpopular with many of his subjects, particularly the priesthood and the military class.[5] To the east, the Persians had been growing in strength under the leadership of Cyrus the Great, who would soon lead a military expedition into Babylonian territory. In October 539 BCE, after the Battle of Opis, the Persian army made entry into the capital city of Babylon. With the success of Cyrus' campaign, Babylonia was incorporated into the Persian realm as a satrapy. As recorded in the Cyrus Cylinder, Cyrus vowed to respect the Babylonian people and also allowed incarcerated peoples to return to their homelands, most notably including the Babylonians' captives from Judah. Consequently, he was viewed as the legitimate successor of the ancient Babylonian kings, and, unlike Nabonidus, rose to become a popular figure in Babylon itself.[2]

A number of factors arose which would ultimately lead to the fall of Babylon. The population of Babylonia became restive and increasingly disaffected under Nabonidus. The Marduk priesthood hated Nabonidus because of his suppression of Marduk's cult and his elevation of the cult of the moon-god Sin.[6][7] He excited a strong feeling against himself by attempting to centralize the religion of Babylonia in the temple of Marduk at Babylon, and thus alienated the local priesthoods.[citation ^needed]
The military party also despised him on account of his antiquarian tastes. He seemed to have left the defense of his kingdom to Belshazzar (a capable soldier but poor diplomat who alienated the political elite), while occupying himself with the more congenial work, like excavating foundation records of the temples and determining the dates of their builders. He also spent time outside Babylonia, rebuilding temples in the Assyrian city of Harran, and also among his Arab subjects in the deserts to the south of Mesopotamia.[citation ^needed]
Nabonidus and Belshazzar's Assyrian heritage is also likely to have added to this resentment. In addition, Mesopotamian military might had usually been concentrated in the martial state of Assyria. Babylonia had always been more vulnerable to conquest and invasion than its northern neighbour, and without the might of Assyria to keep foreign powers in check, Babylonia was ultimately exposed
