Foundation and the fall of Assyria n cities Early in the reign of the Neo-Assyrian king
Sinsharishkun, the southern official or general
Nabopolassar revolted amid ongoing political instability in Assyria, caused by an earlier brief civil war between Sinsharishkun and the general
Sin-shumu-lishir. In 626 BC, Nabopolassar assaulted and successfully seized the cities of Babylon and
Nippur. Sinsharishkun's response was quick and decisive; by October of that year the Assyrians had recaptured Nippur and besieged Nabopolassar at the city of
Uruk. However, Sinsharishkun failed to capture Babylon, and Nabopolassar endured the siege of Uruk, repulsing the Assyrian army. In November 626 BC, Nabopolassar was crowned King of Babylon, restoring Babylonia as an independent kingdom after more than a century of direct Assyrian rule. The Assyrian king had little success in his campaigns in northern Babylonia from 625 to 623 BC, as
Der and other southern cities joined Nabopolassar. Sinsharishkun led a massive counterattack in 623 BC which seemed on a path to victory, but he had to abandon the campaign as a revolt in Assyria threatened his throne at home. This left the Babylonians free to conquer the last remaining Assyrian seats of power in Babylonia from 622 to 620 BC. Both Uruk and Nippur, cities which had shifted the most between Assyrian and Babylonian control, were firmly in Babylonian hands by 620 BC, and Nabopolassar had consolidated his rule over all of Babylonia. After further Babylonian conquests and further failures by Sinsharishkun despite military support from
Egypt, the Assyrian Empire quickly began to fall apart. In October or November 615 BC, the
Medes under King
Cyaxares, also ancient enemies of Assyria, entered the tottering empire and seized the district of
Arrapha, in July or August 614 BC, attacked the cities of
Kalhu and
Nineveh, and finally besieged
Assur, the ancient religious capital of Assyria. The siege was successful and the city endured a brutal sack. Nabopolassar arrived at Assur after the plunder had begun and met with Cyaxares, allying with him and signing an anti-Assyrian pact. In April or May 612 BC, at the start of Nabopolassar's 14th year as King of Babylon, the combined Medo-Babylonian army marched on the Assyrian capital of Nineveh. From June to August, they besieged the city and in August, they breached the walls, leading to another
lengthy and brutal sack, during which Sinsharishkun is assumed to have died. Sinsharishkun's successor,
Ashur-uballit II, the final king of Assyria, was defeated at
Harran in 609 BC. Egypt, Assyria's ally, continued the war against Babylon for a few more years, before being decisively defeated by Nabopolassar's crown prince
Nebuchadnezzar at
Carchemish in 605 BC.
Reign of Nebuchadnezzar II Nebuchadnezzar II succeeded
Nabopolassar in 605 BC upon the death of his father. The empire he inherited was among the most powerful in the world, and he quickly reinforced his father's alliance with the Medes by marrying Cyaxares's daughter or granddaughter,
Amytis. Some sources suggest that the famous
Hanging Gardens of Babylon, one of the
Seven Wonders of the Ancient World, were built by Nebuchadnezzar for his wife to remind her of her homeland (though the existence of these gardens is debated). Nebuchadnezzar's 43-year reign brought with it a golden age for Babylon, which became the most powerful kingdom in the Middle East. Nebuchadnezzar's most famous campaigns today are his wars in the
Levant. These campaigns began relatively early in his reign and were chiefly conducted to consolidate his empire by incorporating the newly independent kingdoms and city-states which had been vassals of the defeated Neo-Assyrian Empire. His 587 BC destruction of Jerusalem ended the
Kingdom of Judah and scattered its populace, with many of its elite citizens taken as prisoners to Babylon, initiating a period known as the
Babylonian Captivity. Nebuchadnezzar subsequently
besieged Tyre for 13 years. Though he did not capture the city, invulnerable on an island 800 metres from the coast which could not be taken without naval support, it eventually surrendered to him in 573 BC, agreeing to be ruled by vassal kings. Tyre was never captured until
Alexander the Great's
siege in 332 BC. It is possible that Nebuchadnezzar campaigned against Egypt in 568–567 BC, given that a fragmentary Babylonian inscription, given the modern designation BM 33041, from that year records the word "Egypt" as well as possibly traces of the name "Amasis" (the name of the then incumbent Pharaoh,
Amasis II, 570–526 BC). A stele of Amasis from the 4th year of his reign in 567 BC, also fragmentary, may also describe a combined naval and land attack by the Babylonians. Recent evidence suggests that the Babylonians were initially successful during the invasion and gained a foothold in Egypt, but they were repelled by Amasis' forces. Evidence for this campaign is scant, and historians believe that if Nebuchadnezzar launched another campaign, he was unsuccessful. (However, some have suggested that Nebuchadnezzar came to defeat Apries, with the combined forces of Amasis and Nebuchadnezzar managing to kill him, securing Amasis' throne, though as a vassal king.) In addition to his military exploits, Nebuchadnezzar was a great builder, famous for his monuments and building works throughout Mesopotamia, such as Babylon's
Ishtar Gate and Processional Street. He is known to have completely renovated at least 13 cities, but spent most of his time and resources on the capital, Babylon. By 600 BC, the Babylonians and possibly their subject peoples saw Babylon as the literal and figurative center of the world. Nebuchadnezzar widened Processional Street and fitted it with new decorations, making the annual
New Year's Festival, honoring the city's patron deity
Marduk, more spectacular than ever before.
Later history exhibited in the British Museum. The king is shown praying to the
Moon, the
Sun and
Venus and is depicted as being the closest to the Moon. After Nebuchadnezzar II, the empire fell into political turmoil and instability. His son and successor,
Amel-Marduk, reigned for only two years before being assassinated in a coup by the influential courtier
Neriglissar. Neriglissar was a , a governor of one of the eastern provinces, and had been present during several of Nebuchadnezzar's campaigns. Importantly, Neriglissar was also married to one of Nebuchadnezzar's daughters and thus linked to the royal family. Possibly due to old age, Neriglissar's reign was also short, with some of its few recorded activities being the restoration of some monuments in Babylon and a campaign in
Cilicia. Neriglissar died in 556 BC and was succeeded by his underage son,
Labashi-Marduk. Labashi-Marduk's reign was even briefer: he was assassinated after just nine months. The perpetrators of the assassination, the influential courtier
Nabonidus and his son
Belshazzar, then took power; despite the palace turmoil, the empire remained relatively calm. Nabonidus began his reign with traditional royal duties: renovating buildings and monuments, worshipping the gods, and waging war (campaigning in Cilicia). He was not of Babylonian ancestry, originating from Harran in former Assyria, a city devoted to the moon god
Sîn, which may have antagonized the Babylonian clergy. Nabonidus also clashed with the clergy when he tightened government control over the temples in an attempt to reform their management. Nabonidus left Babylonia to campaign in the Levant, unaccountably settling for ten years in the conquered city of
Tayma in northern
Arabia, while the crown prince Belshazzar was left to govern Babylonia. Returning , Nabonidus reorganized his court and removed some of its powerful members.
Fall of Babylon during his 539 BC invasion of Babylonia. In 549 BC
Cyrus the Great, the
Achaemenid king of
Persia, revolted against the
Median king
Astyages at
Ecbatana. Astyages' army betrayed him and Cyrus established himself as ruler of all the
Iranian peoples, as well as the
Elamites and
Gutians, ending the Median Empire and establishing the
Achaemenid Empire. Ten years after his victory against the Medes, Cyrus invaded Babylon. Nabonidus sent Belshazzar to meet the Persian army, but the Babylonian forces were defeated at the
Battle of Opis. On 12 October, after Cyrus's engineers diverted the waters of the Euphrates, the soldiers of Cyrus entered Babylon without the need for battle. Nabonidus surrendered and was deported. Gutian guards were placed at the gates of the great temple of Marduk, where services continued without interruption. Cyrus claimed to be the legitimate successor of the ancient Babylonian kings and the avenger of Marduk over Nabonidus's supposed impiety. Cyrus's conquest was welcomed by the Babylonian populace, whether as a genuine liberator or an undeniable conqueror. Cyrus's invasion of Babylonia may have been helped by foreign exiles such as the Jews. Accordingly, one of his first acts was to allow these exiles to return to their homelands, carrying their sacred images and vessels. This was explicitly granted in a proclamation, the
Cyrus Cylinder, in which Cyrus also justifies his conquests as the will of Marduk. Babylon never again attained the status of an independent state. == Aftermath and legacy ==
