During this period people began to use the names of ancestors as a kind of family name; this increase in family consciousness is probably an indication that the number of old families was growing smaller. By this time the process of “Aramaicization” had reached even the oldest cities of Babylonia and Assyria.
Apparently this era was not very fruitful for literature either in Babylonia or in Assyria. In Assyria numerous royal inscriptions, some as long as 1,300 lines, were among the most important texts; some of them were diverse in content and well composed. Most of the hymns and prayers were written in the traditional style. Many oracles, often of unusual content, were proclaimed in the Assyrian dialect, most often by the priestesses of the goddess Ishtar of Arbela. In Assyria as in Babylonia, the beginnings of a real historical literature are observed; most of the authors have remained anonymous up to the present.
The many gods of the tradition were worshiped in Babylonia and Assyria in large and small temples, as in earlier times. Very detailed rituals regulated the sacrifices, and the interpretations of the ritual performances in the cultic commentaries were rather different and sometimes very strange.
On some of the temple towers (ziggurats), astronomical observatories were installed. The earliest of these may have been the observatory of the Ninurta temple at Kalakh in Assyria, which dates back to the 9th century bce; it was destroyed with the city in 612. The most important observatory in Babylonia from about 580 was situated on the ziggurat Etemenanki, a temple of Marduk in Babylon. In Assyria the observation of the Sun, Moon, and stars had already reached a rather high level; the periodic recurrence of eclipses was established. After 600, astronomical observation and calculations developed steadily, and they reached their high point after 500, when Babylonian and Greek astronomers began their fruitful collaboration. Incomplete astronomical diaries, beginning in 652 and covering some 600 years, have been preserved. Decline of the Assyrian empire
Few historical sources remain for the last 30 years of the Assyrian empire. There are no extant inscriptions of Ashurbanipal after 640 bce, and the few surviving inscriptions of his successors contain only vague allusions to political matters. In Babylonia the silence is almost total until 625 bce, when the chronicles resume. The rapid downfall of the Assyrian empire was formerly attributed to military defeat, although it was never clear how the Medes and the Babylonians alone could have accomplished this. More recent work has established that after 635 a civil war occurred, weakening the empire so that it could no longer stand up against a foreign enemy. Ashurbanipal had twin sons. Ashur-etel-ilani was appointed successor to the throne, but his twin brother Sin-shar-ishkun did not recognize him. The fight between them and their supporters forced the old king to withdraw to Harran, in 632 at the latest, perhaps ruling from there over the western part of the empire until his death in 627. Ashur-etel-ilani governed in Assyria from about 633, but a general, Sin-shum-lisher, soon rebelled against him and proclaimed himself counter-king. Some years later (629?) Sin-shar-ishkun finally succeeded in obtaining the kingship. In Babylonian documents dates can be found for all three kings. To add to the confusion, until 626 there are also dates of Ashurbanipal and a king named Kandalanu. In 626 the Chaldean Nabopolassar (Nabu-apal-uṣur) revolted from Uruk and occupied Babylon. There were several changes in government. King Ashur-etel-ilani was forced to withdraw to the west, where he died sometime after 625.
About the year 626 the Scythians laid waste to Syria and Palestine. In 625 the Medes became united under Cyaxares and began to conquer the Iranian provinces of Assyria. One chronicle relates of wars between Sin-shar-ishkun and Nabopolassar in Babylonia in 625–623. It was not long until the Assyrians were driven out of Babylonia. In 616 the Medes struck against Nineveh, but, according to the Greek historian Herodotus, were driven back by the Scythians. In 615, however, the Medes conquered Arrapkha (Kirkūk), and in 614 they took the old capital of Ashur, looting and destroying the city. Now Cyaxares and Nabopolassar made an alliance for the purpose of dividing Assyria. In 612 Kalakh and Nineveh succumbed to the superior strength of the allies. The revenge taken on the Assyrians was terrible: 200 years later Xenophon found the country still sparsely populated.
Sin-shar-ishkun, king of Assyria, found death in his burning palace. The commander of the Assyrian army in the west crowned himself king in the city of Harran, assuming the name of the founder of the empire, Ashur-uballiṭ II (611–609 bce). Ashur-uballiṭ had to face both the Babylonians and the Medes. They conquered Harran in 610, without, however, destroying the city completely. In 609 the remaining Assyrian troops had to capitulate. With this event Assyria disappeared from history. The great empires that succeeded it learned a great deal from the hated Assyrians, both in the arts and in the organization of their states. The Neo-Babylonian Empire
The Chaldeans, who inhabited the coastal area near the Persian Gulf, had never been entirely pacified by the Assyrians. About 630 Nabopolassar became king of the Chaldeans. In 626 he forced the Assyrians out of Uruk and crowned himself king of Babylonia. He took part in the wars aimed at the destruction of Assyria. At the same time, he began to restore the dilapidated network of canals in the cities of Babylonia, particularly those in Babylon itself. He fought against the Assyrian Ashur-uballiṭ II and then against Egypt, his successes alternating with misfortunes. In 605 Nabopolassar died in Babylon. Nebuchadrezzar II
Nabopolassar had named his oldest son, Nabu-kudurri-uṣur, after the famous king of the second dynasty of Isin, trained him carefully for his prospective kingship, and shared responsibility with him. When the father died in 605, Nebuchadrezzar was with his army in Syria; he had just crushed the Egyptians near Carchemish in a cruel, bloody battle and pursued them into the south. On receiving the news of his father’s death, Nebuchadrezzar returned immediately to Babylon. In his numerous building inscriptions he tells but rarely of his many wars; most of them end with prayers. The Babylonian chronicle is extant only for the years 605–594, and not much is known from other sources about the later years of this famous king. He went very often to Syria and Palestine, at first to drive out the Egyptians. In 604 he took the Philistine city of Ashkelon. In 601 he tried to push forward into Egypt but was forced to pull back after a bloody, undecided battle and to regroup his army in Babylonia. After smaller incursions against the Arabs of Syria, he attacked Palestine at the end of 598. King Jehoiakim of Judah had rebelled, counting on help from Egypt. According to the chronicle, Jerusalem was taken on March 16, 597. Jehoiakim had died during the siege, and his son, King Johoiachin, together with at least 3,000 Jews, was led into exile in Babylonia. They were treated well there, according to the documents. Zedekiah was appointed the new king. In 596, when danger threatened from the east, Nebuchadrezzar marched to the Tigris River and induced the enemy to withdraw. After a revolt in Babylonia had been crushed with much bloodshed, there were other campaigns in the west.
According to the Hebrew Bible, Judah rebelled again in 589, and Jerusalem was placed under siege. The city fell in 587/586 and was completely destroyed. Many thousands of Jews were forced into “Babylonian exile,” and their country was reduced to a province of the Babylonian empire. The revolt had been caused by an Egyptian invasion that pushed as far as Sidon. Nebuchadrezzar laid siege to Tyre for 13 years without taking the city, because there was no fleet at his disposal. In 568/567 he attacked Egypt, again without much success, but from that time on the Egyptians refrained from further attacks on Palestine. Nebuchadrezzar lived at peace with Media throughout his reign and acted as a mediator after the Median-Lydian war of 590–585.
