account for a period of two weeks. Two years later, Babylon produced another rebel leader, Shamash-eriba. Beginning in the summer of 482 BC, Shamash-eriba seized Babylon itself and other nearby cities, such as Borsippa and Dilbat, and was only defeated in March 481 BC after a lengthy siege of Babylon. The precise cause of the unrest in Babylon is uncertain. It may have been due to tax increase. Prior to these revolts, Babylon had occupied a special position within the Achaemenid Empire, the Achaemenid kings had been titled as "King of Babylon" and "King of the Lands", perceiving Babylonia as a somewhat separate entity within their empire, united with their own kingdom in a personal union. Xerxes dropped "King of Babylon" from his titulature and divided the previously large Babylonian satrapy (accounting for most of the Neo-Babylonian Empire's territory) into smaller sub-units. Using texts written by classical authors, it is often assumed that Xerxes enacted a brutal vengeance on Babylon following the two revolts. According to ancient writers, Xerxes destroyed Babylon's fortifications and damaged the temples in the city. The Esagila was allegedly exposed to great damage and Xerxes allegedly carried the statue of Marduk away from the city, possibly bringing it to Iran and melting it down (classical authors held that the statue was entirely made of gold, which would have made melting it down possible). Modern historian Amélie Kuhrt considers it unlikely that Xerxes destroyed the temples, but believes that the story of him doing so may derive from an anti-Persian sentiment among the Babylonians. It is doubtful if the statue was removed from Babylon at all and some have even suggested that Xerxes did remove a statue from the city, but that this was the golden statue of a man rather than the statue of the god Marduk. Though mentions of it are lacking considerably compared to earlier periods, contemporary documents suggest that the Babylonian New Year's Festival continued in some form during the Achaemenid period. Because the change in rulership from the Babylonians themselves to the Persians and due to the replacement of the city's elite families by Xerxes following its revolt, it is possible that the festival's traditional rituals and events had changed considerably.
