Assyria,
Aramean states and their neighbors The region that the Chaldeans eventually made their homeland was in relatively poor southeastern Mesopotamia, at the head of the Persian Gulf. They appear to have migrated into southern
Babylonia from the Levant at some unknown point between the end of the reign of
Ninurta-kudurri-usur II (a contemporary of
Tiglath-Pileser II) circa 940 BC, and the start of the reign of
Marduk-zakir-shumi I in 855 BC, although there is no historical proof of their existence prior to the late 850s BC. For perhaps a century or so after settling in the area, these semi-nomadic migrant Chaldean tribes had no impact on the pages of history, seemingly remaining subjugated by the native
Akkadian speaking kings of Babylon or by perhaps regionally influential Aramean tribes. The main players in southern Mesopotamia during this period were Babylonia and Assyria, together with
Elam to the east and the
Aramaeans, who had already settled in the region a century or so prior to the arrival of the Chaldeans. The very first written historical attestation of the existence of Chaldeans occurs in 852 BC, in the annals of the Assyrian king
Shalmaneser III, who mentions invading the southeastern extremes of Babylonia and subjugating one
Mushallim-Marduk, the chief of the
Amukani tribe and overall leader of the Kaldu tribes, together with capturing the town of
Baqani, extracting tribute from
Adini, chief of the
Bet-Dakkuri, another Chaldean tribe. Shalmaneser III had invaded Babylonia at the request of its own king,
Marduk-zakir-shumi I, who, being threatened by his own rebellious relations, together with powerful Aramean tribes pleaded with the more powerful Assyrian king for help. The subjugation of the Chaldean tribes by the Assyrian king appears to have been an aside, as they were not at that time a powerful force or a threat to the native Babylonian king. Important Kaldu tribes and their regions in southeastern Babylonia were
Bit-Yâkin (the original area the Chaldeans settled in on the Persian Gulf),
Bet-Dakuri,
Bet-Adini,
Bet-Amukkani, and
Bet-Shilani. and the former Assyrian possessions of
Aram (
Syria),
Phoenicia,
Israel,
Cyprus,
Edom,
Philistia, and parts of
Arabia, while the Medes took control of the former Assyrian colonies in
Ancient Iran,
Asia Minor and the
Caucasus. Nabopolassar was not able to enjoy his success for long, dying in 604 BC, only one year after the victory at Karchemish. He was succeeded by his son, who took the name
Nebuchadnezzar II, after the unrelated 12th century BC native Akkadian-Babylonian king
Nebuchadnezzar I, indicating the extent to which the migrant Chaldeans had become infused with native Mesopotamian culture.
Nebuchadnezzar II and his allies may well have been forced to deal with remnants of Assyrian resistance based in and around
Dur-Katlimmu, as Assyrian imperial records continue to be dated in this region between 604 and 599 BC. In addition, the Egyptians remained in the region an attempt to revive the Asian colonies of the ancient Egyptian Empire. Nebuchadnezzar II was to prove himself to be the greatest of the Chaldean rulers, rivaling another non-native ruler, the 18th century BC
Amorite king
Hammurabi, as the greatest king of Babylon. He was a patron of the cities and a spectacular builder, rebuilding all of Babylonia's major cities on a lavish scale. His building activity at Babylon, expanding on the earlier major and impressive rebuilding of the Assyrian king
Esarhaddon, helped to turn it into the immense and beautiful city of legend. Babylon covered more than , surrounded by moats and ringed by a double circuit of walls. The Euphrates flowed through the center of the city, spanned by a beautiful stone bridge. At the center of the city rose the giant
ziggurat called
Etemenanki, "House of the Frontier Between Heaven and Earth," which lay next to the Temple of
Marduk. He is also believed by many historians to have built
The Hanging Gardens of Babylon (although others believe these gardens were built much earlier by an Assyrian king in Nineveh) for his wife, a
Median princess from the green mountains, so that she would feel at home. A capable leader, Nebuchadnezzar II conducted successful military campaigns; cities like
Tyre,
Sidon and
Damascus were subjugated. He also conducted numerous campaigns in
Asia Minor against the
Scythians,
Cimmerians, and
Lydians. Like their Assyrian relations, the Babylonians had to campaign yearly in order to control their colonies. In 601 BC, Nebuchadnezzar II was involved in a major but inconclusive battle against the
Egyptians. In 599 BC, he invaded Arabia and routed the Arabs at
Qedar. In 597 BC, he invaded
Judah, captured
Jerusalem after the
siege of Jerusalem (597 BC) and deposed its king
Jehoiachin, carrying the Israelites into
captivity in Babylon. Egyptian and Babylonian armies fought each other for control of the Near East throughout much of Nebuchadnezzar's reign, and this encouraged king
Zedekiah of Judah to revolt. After an eighteen-month siege, Jerusalem was captured in 587 BC, thousands of Jews were deported to Babylon, and Solomon's Temple was razed to the ground. Nebuchadnezzar successfully fought the Pharaohs
Psammetichus II and
Apries throughout his reign, and during the reign of Pharaoh
Amasis in 568 BC it is rumoured that he may have briefly invaded Egypt itself. By 572, Nebuchadnezzar was in full control of Babylonia, Chaldea,
Aramea (
Syria),
Phonecia, Israel,
Judah,
Philistia,
Samarra,
Jordan, northern Arabia, and parts of
Asia Minor. Nebuchadnezzar died of illness in 562 BC after a one-year co-reign with his son,
Amel-Marduk, who was deposed in 560 BC after a reign of only two years.
End of the Chaldean dynasty Neriglissar succeeded Amel-Marduk. It is unclear as to whether he was in fact an ethnic Chaldean or a native Babylonian nobleman, as he was not related by blood to Nabopolassar's descendants, having married into the ruling family. He conducted successful military campaigns against the
Hellenic inhabitants of
Cilicia, which had threatened Babylonian interests. Neriglissar reigned for only four years and was succeeded by the youthful
Labashi-Marduk in 556 BC. Again, it is unclear whether he was a Chaldean or a native Babylonian. Labashi-Marduk reigned only for a matter of months, being deposed by
Nabonidus in late 556 BC. Nabonidus was certainly not a Chaldean, but an Assyrian from
Harran, the last capital of Assyria, and proved to be the final native Mesopotamian king of Babylon. He and his son, the regent
Belshazzar, were deposed by the Persians under
Cyrus the Great in 539 BC. When the Babylonian Empire was absorbed into the Persian
Achaemenid Empire, the name "Chaldean" lost its meaning in reference to a particular ethnicity or land, but lingered for a while as a term solely and explicitly used to describe a societal class of astrologers and astronomers in southern Mesopotamia. The original Chaldean tribe had long ago became Akkadianized, adopting Akkadian culture, religion, language and customs, blending into the majority native population, and eventually wholly disappearing as a distinct race of people, as had been the case with other preceding migrant peoples, such as the Amorites, Kassites, Suteans and Arameans of Babylonia. The Persians considered this
Chaldean societal class to be masters of reading and writing, and especially versed in all forms of
incantation, sorcery,
witchcraft, and the magical arts. They spoke of astrologists and astronomers as
Chaldeans, and it is used with this specific meaning in the
Book of Daniel (Dan. i. 4, ii. 2 et seq.) and by classical writers, such as
Strabo. The disappearance of the Chaldeans as an ethnicity and Chaldea as a land is evidenced by the fact that the Persian rulers of the
Achaemenid Empire (539–330 BC) did not retain a province called "Chaldea", nor did they refer to "Chaldeans" as a race of people in their written annals. This is in contrast to Assyria, and for a time Babylonia also, where the Persians retained the names Assyria and Babylonia as designations for distinct
geo-political entities within the Achaemenid Empire. In the case of the Assyrians in particular, Achaemenid records show Assyrians holding important positions within the empire, particularly with regards to military and civil administration. ==Legacy==
