  Nothing is known of Persia–Babylon relations between 547 and 539 BC, but it is likely that there were hostilities between the two empires for several years leading up to the war of 540–539 BC and the Fall of Babylon. In October 539 BC, Cyrus won a battle against the Babylonians at Opis, then took Sippar without a fight before finally capturing the city of Babylon on 12 October, where the Babylonian king Nabonidus was taken prisoner. Upon taking control of the city, Cyrus depicted himself in propaganda as restoring the divine order which had been disrupted by Nabonidus, who had promoted the cult of Sin rather than Marduk, and he also portrayed himself as restoring the heritage of the Neo-Assyrian Empire by comparing himself to the Assyrian king Ashurbanipal. The Hebrew Bible also unreservedly praises Cyrus for his actions in the conquest of Babylon, referring to him as Yahweh 's anointed. He is credited with freeing the people of Judah from their exile and with authorizing the reconstruction of much of Jerusalem, including the Second Temple.
