Assyrian campaigns in Media At the end of the 2nd millennium BCE, Median tribes began settling in the territory of future Media in western Iran. From the 9th century BCE, the Assyrians regularly invaded and plundered regions in northwest Iran, where numerous small principalities existed at that time. The first mention of the Medes in Assyrian texts dates back to 834 BCE when the Assyrian king
Shalmaneser III (r. 858–824 BCE) returned from a military campaign, passing through the Median territory in the Hamadan plain. The Medes formed numerous small entities under tribal chiefs, and despite subduing several Median chiefs, Assyrian kings never conquered all of Media. Frequent Assyrian attacks compelled various inhabitants of Media to cooperate and develop more effective leadership. The Assyrians valued goods from the east, such as Bactrian lapis lazuli, and the east-west trade route through Media became increasingly crucial. Trade might explain Ecbatana's rise as the central city of Media and could have triggered the unification process. Judging by Assyrian sources, no unified Median state, as described by Herodotus for the reign of Deioces, existed in the early 7th century BCE. His account is at best a Median legend about the foundation of their kingdom. In
Ashurbanipal’s reign (r. 668–630 BCE), references to the Medes become very sparse. Ashurbanipal reports that three Median city lords had rebelled against Assyrian rule were defeated and brought to Nineveh during his fifth campaign in 656 BCE. This is the last mention of Medes in the Assyrian sources. The fact that the three Median rulers are described as city lords may indicate that the powers structure among the Medes at this time was the same as in the 8th century. It is unknown whether the Assyrian provinces in the Zagros, Parsua, Bīt-Hamban, Kišesim (Kār-Nergal) and Harhar (Kar-Sarrukin), were still part of the empire during Ashurbanipal's reign. everything seems to indicate that the Assyrians were losing control over the provinces established in the Zagros. This could have created room for the development of a unified Median state and although Assyrian sources make no reference to a united Median territorial state that would be comparable to Assyria itself or other contemporary principalities such as Elam, Mannea or Urartu, many scholars remain reluctant to assign no historical relevance whatsoever to Herodotus' account. From 627 BCE onward the Assyrians were definitely in serious trouble both at home and in Babylonia and, therefore, the Median kingdom most likely emerged after 627, or possibly already after 631 BCE. Herodotus reports that Cyaxares, wanting to avenge his father's death, marched with the army toward the Assyrian capital, Nineveh, with the aim of destroying the city. While besieging Nineveh, the Medes were attacked by a large Scythian army under the command of
Madyes, son of
Bartatua. A battle ensued, in which the Medes were defeated, losing their power in Asia, which was entirely taken over by the Scythians.
Fall of the Assyrian Empire After the death of
Ashurbanipal in 631 BCE, the Assyrian Empire entered a period of political instability. In 626 BCE, the
Babylonians rebelled against Assyrian domination. Nabopolassar, governor of southern regions and leader of the revolt, was soon recognized as king of Babylon. Nabopolassar gained control of Babylon but not all of Babylonia from the Assyrians and was engaged in serious fighting, he must have been looking for any possible allies. Interestingly, Herodotus mentions that the Median king Phraortes was killed around 625 BCE during an unsuccessful invasion of Assyria. There is no evidence regarding the relations between the Medes and Assyrians from 624 to 617 BCE. It is unknown whether the Medes were still geographically separated from the Assyrian heartland by the Zagros Mountains and surrounding peoples, or if they were already asserting themselves in the mountainous Assyrian provinces, particularly in Mazamua (modern
Suleimaniya). However, for the subsequent years from 616 to 595, much of the
Babylonian Chronicle is preserved and provides reasonably reliable account of events. The source is not a complete record of the history of the period, and is focused exclusively on events in Mesopotamia. Afterwards Cyaxares and his army went home. In 613 BCE, the Medes are not mentioned in the chronicle. However, in 612 BCE, a king of the
ummān-manda appears on the scene; he is surely identical with the king of the Medes, although it is strange that a single cuneiform tablet should describe one people by two different terms. The combined military forces of Cyaxares and Nabopolassar laid siege to Nineveh, resulting in its fall after three months. After the sack of the Assyrian capital, only the Babylonians seem to have continued the campaign and a part of the Babylonian army marched on
Nasibina and
Rasappa, while Cyaxares and his army returned to Media. Meanwhile the Assyrians were regrouping under a new king further west at
Harran. The Medes appear to be absent from the account of 611 BCE, while the Babylonians are militarily active advancing towards Syria and the upper Euphrates. The Medes reappeared on the scene in 610 BCE, when they joined the Babylonians for an assault on Harran. Faced with the formidable alliance, the Assyrians and their Egyptian allies abandoned Harran, which was captured. After that, the Medes then departed for the last time In 605 BCE, the Babylonians marched to
Carchemish and conquered it, completely defeating the Assyrians and Egyptians. It is not clear whether the Medes also participated in this final defeat of the Assyrians. The outcome of the fall of Assyria for Median territorial expansion is unknown, but the
Babylonian Chronicle and other evidence imply that most of the former Assyrian territory came under Babylonian control.
Mario Liverani argues against the notion that the Medes and Babylonians shared Assyrian territory; instead, the Medes simply took over the Zagros, which Assyria had already lost earlier. The Cimmerian power, once great and significant in Cappadocia, collapsed almost simultaneously with Urartu. This created an opportunity for the Medes, who, after conquering Urartu, entered Asia Minor, subjugating Cappadocia. This region might have been familiar to them, as Assyrian texts from the 7th century BCE describe the situation in Anatolia west of the Euphrates similarly to the Zagros region.
Aria and
Bactria, becoming an empire that stretched from Anatolia in the west to Central Asia in the east. Whatever the political role of the Medes in the east, the representation of an Indian embassy at the court of Cyaxares (
Xenophon,
Cyropaedia 2.4.1) seems a plausible outcome of commercial contacts. Cyaxares died shortly after the treaty with the Lydians, leaving the throne to his son Astyages. During his reign, Astyages may have worked to strengthen and centralize the Median state, contrary to the will of the tribal nobility. This may have contributed to the downfall of the kingdom. According to Ctesias, the Median kings also fought wars against the
Cadusians and the
Sacae, although there is no hard evidence to back this up. Nevertheless, the reference to a war against the Sacae might indicate continued challenges from nomadic incursions, while the narrative about the war against the Cadusians might indicate that the Medes had limited control over the southern shores of the Caspian Sea, where the Cadusians lived. Taking control of Media may have implied taking control of vassal states like Armenia, Cappadocia, Parthia, Drangiana, and Aria. If Cyrus was indeed the grandson of Astyages as Herodotus claims, then this would explain why the Medes accepted his reign. However, it is also possible that the connection between Cyrus and Astyages was invented to justify Persian rule over the Medes. According to Ctesias, Astyages had a daughter named
Amytis, who was married to
Spitamas, who then became the presumptive successor to his father-in-law. After killing Spitamas, Cyrus would have married Amytis to gain legitimacy. Although the authenticity of Ctesias's account is questionable, it is very likely that Cyrus married a daughter of the Median king. After Astyages's defeat, the Lydian king Croesus crossed the Halys River in hopes of expanding his borders to the east. This resulted in a war, leading Lydia to be conquered by the Persians. A Sagartian named
Tritantechmes, who also claimed to be a descendant of Cyaxares, continued the rebellion but was also defeated. This is the last Median rebellion against Achaemenid rule. After the end of the Achaemenid Empire, Media continued to have great importance under the later
Seleucid and
Parthian empires. == Historicity ==
