Background
When the Assyrian capital, Nineveh, was overrun by the Medes, Scythians, Babylonians and their allies in 612 BC, the Assyrians moved their capital to Harran. When Harran was captured by the alliance in 609 BC, [7] ending the Assyrian Empire, remnants of the Assyrian army joined Carchemish, a city under Egyptian rule, on the Euphrates. Egypt, a former vassal of Assyria, was allied with Assyrian King Ashur-uballit II and marched in 609 BC to his aid against the Babylonians. [8]
The Egyptian army of Pharaoh Necho II was delayed at Megiddo by the forces of King Josiah of Judah. Josiah was killed, and his army was defeated at the Battle of Megiddo. [9]
The Egyptians and the Assyrians together crossed the Euphrates and laid siege to Harran, which they failed to retake. They then retreated to northwestern Assyria in what is now northeastern Syria.
Chaldea was a small country that existed between the late 10th or early 9th and mid-6th centuries BC, after which the country and its people were absorbed and assimilated into the indigenous population of Babylonia. Semitic-speaking, it was located in the marshy land of the far southeastern corner of Mesopotamia and briefly came to rule Babylon. The Hebrew Bible uses the term כשדים (Kaśdim) and this is translated as Chaldaeans in the Greek Old Testament, although there is some dispute as to whether Kasdim in fact means Chaldean or refers to the south Mesopotamian Kaldu.
The 7th century BC began the first day of 700 BC and ended the last day of 601 BC.
Babylonia was an ancient Akkadian-speaking state and cultural area based in the city of Babylon in central-southern Mesopotamia. It emerged as an Akkadian populated but Amorite-ruled state c. 1894 BC. During the reign of Hammurabi and afterwards, Babylonia was retrospectively called "the country of Akkad", a deliberate archaism in reference to the previous glory of the Akkadian Empire. It was often involved in rivalry with the older ethno-linguistically related state of Assyria in the north of Mesopotamia and Elam to the east in Ancient Iran. Babylonia briefly became the major power in the region after Hammurabi created a short-lived empire, succeeding the earlier Akkadian Empire, Third Dynasty of Ur, and Old Assyrian Empire. The Babylonian Empire rapidly fell apart after the death of Hammurabi and reverted to a small kingdom centered around the city of Babylon.

Nebuchadnezzar II, also spelled Nebuchadrezzar II, was the second king of the Neo-Babylonian Empire, ruling from the death of his father Nabopolassar in 605 BC to his own death in 562 BC. Historically known as Nebuchadnezzar the Great, he is typically regarded as the empire's greatest king. Nebuchadnezzar remains famous for his military campaigns in the Levant, for his construction projects in his capital, Babylon, including the Hanging Gardens of Babylon, and for the role he plays in Jewish history. Ruling for 43 years, Nebuchadnezzar was the longest-reigning king of the Babylonian dynasty. By the time of his death, he was among the most powerful rulers in the world.
Necho II of Egypt was a king of the 26th Dynasty, which ruled from Sais. Necho undertook a number of construction projects across his kingdom. In his reign, according to the Greek historian Herodotus, Necho II sent out an expedition of Phoenicians, which in three years sailed from the Red Sea around Africa to the Strait of Gibraltar and back to Egypt. His son, Psammetichus II, upon succession may have removed Necho's name from monuments.
Nabopolassar was the founder and first king of the Neo-Babylonian Empire, ruling from his coronation as king of Babylon in 626 BC to his death in 605 BC. Though initially only aimed at restoring and securing the independence of Babylonia, Nabopolassar's uprising against the Neo-Assyrian Empire, which had ruled Babylonia for more than a century, eventually led to the complete destruction of the Assyrian Empire and the rise of the Neo-Babylonian Empire in its place.
The year 605 BC was a year of the pre-Julian Roman calendar. In the Roman Empire, it was known as year 149 Ab urbe condita. The denomination 605 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Cyaxares was the third king of the Medes. Cyaxares ascended to the throne in 625 BCE, after his father Phraortes lost his life in a battle against the Assyrians.
This Battle of Megiddo is recorded as having taken place in 609 BC, when Pharaoh Necho II of Egypt led his army to Carchemish to join with his allies, the fading Neo-Assyrian Empire, against the surging Neo-Babylonian Empire. This required passing through territory controlled by the Kingdom of Judah. The Judaean king Josiah refused to let the Egyptians pass. The Judaean forces battled the Egyptians at Megiddo, resulting in Josiah's death and his kingdom becoming a vassal state of Egypt. The battle is recorded in the Hebrew Bible, the Greek 1 Esdras, and the writings of Jewish historian Josephus.
The Battle of Nineveh is conventionally dated between 613 and 611 BC, with 612 BC being the most supported date. Rebelling against the Assyrians, an allied army which combined the forces of Medes and the Babylonians besieged Nineveh and sacked 750 hectares of what was, at that time, one of the greatest cities in the world. The fall of Nineveh led to the destruction of the Neo-Assyrian Empire over the next three years as the dominant state in the Ancient Near East. Archeological records show that the capital of the once mighty Assyrian Empire was extensively de-urbanized and depopulated in the decades and centuries following the battle. A garbled account of the fall of the city later led to the story of the legendary king Sardanapalus.
The Fall of Harran refers to the siege and capture of the Assyrian city of Harran by the Median and Neo-Babylonian empires.
The Battle of Hamath, sometimes called the Battle of Hama, took place between the Babylonians and the fleeing remnants of the Egyptian army defeated at Carchemish. It was fought near the ancient city Hamath on the Orontes.
Aššur-uballiṭ II, also spelled Assur-uballit II and Ashuruballit II, was the final ruler of Assyria, ruling from his predecessor Sîn-šar-iškun's death at the Fall of Nineveh in 612 BC to his own defeat at Harran in 609 BC. He was possibly the son of Sîn-šar-iškun and likely the same person as a crown prince mentioned in inscriptions at the Assyrian capital of Nineveh in 626 and 623 BC.
The Medo-Babylonian conquest of the Assyrian Empire was the last war fought by the Neo-Assyrian Empire, between 626 and 609 BC. Succeeding his brother Ashur-etil-ilani, the new king of Assyria, Sinsharishkun, immediately faced the revolt of one of his brother's chief generals, Sin-shumu-lishir, who attempted to usurp the throne for himself. Though this threat was dealt with relatively quickly, the instability caused by the brief civil war may have made it possible for another official or general, Nabopolassar, to rise up and seize power in Babylonia. Sinsharishkun's inability to defeat Nabopolassar, despite repeated attempts over the course of several years, allowed Nabopolassar to consolidate power and form the Neo-Babylonian Empire, restoring Babylonian independence after more than a century of Assyrian rule. The Neo-Babylonian Empire, and the newly-formed Median Empire under King Cyaxares, then invaded the Assyrian heartland. In 614 BC, the Medes captured and sacked Assur, the ceremonial and religious heart of the Assyrian Empire, and in 612 BC, their combined armies attacked and razed Nineveh, the Assyrian capital. Sinsharishkun's fate is unknown but it is assumed that he died in the defense of his capital. He was succeeded as king only by Ashur-uballit II, possibly his son, who rallied what remained of the Assyrian army at the city of Harran and, bolstered by an alliance with Egypt, ruled for three years, in a last attempt to resist the Medo-Babylonian invasion of his realm.
After the death of Assurbanipal in 631 BC, the Neo-Assyrian Empire entered a period of instability. This was the moment when the Babylonian ruler, Nabopolassar, led a revolt against Assyrian rule. After a few years of war, the Babylonians expelled the Assyrian forces from their territory.
The Assyrian conquest of Egypt covered a relatively short period of the Neo-Assyrian Empire from 673 to 663 BCE. The conquest of Egypt not only placed a land of great cultural prestige under Assyrian rule but also brought the Neo-Assyrian Empire to its greatest extent.
The Siege of Kimuhu is a siege launched by the Egyptian army led by Necho II on the city of Kimukho east of the Euphrates River, where the Egyptian army besieged the city for four months, and the siege ended with the surrender of the Babylonian garrison and the city under Egyptian control.
The Battle of Quramati took place on the east of the Euphrates River between the Egyptian army and the Babylonian army. The battle ended with the defeat of the Babylonians.
