The coming of the Iranians

Though isolated groups of speakers of Indo-European languages had appeared and disappeared in western Iran in the 2nd millennium bc, it was during the Iron Age that the Indo-European Iranians rose to be the dominant force on the plateau. By the mid-9th century bc two major groups of Iranians appeared in cuneiform sources: the Medes and the Persians. Of the two the Medes were the more widespread and, from an Assyrian point of view, the more important group. When Assyrian armies raided as far east as modern Hamadān, they found only Medes. In the more western Zagros they encountered Medes mixed with non-Iranian indigenous peoples. Early in the 1st millennium Iranian Medes already controlled almost all of the eastern Zagros and were infiltrating, if not actually pushing steadily into, the western Zagros, in some areas right up to the edge of the plateau and to the borders of lowland Mesopotamia. Persians also appear in roughly the same areas, though their exact location remains controversial. At times they seem to have settled in the north near Lake Urmia, at times in the central western Zagros near modern Kermānshāh, later certainly in the southwestern Zagros somewhere near the borders of Elam, and eventually, of course, in the region of Fārs. It has been argued that these various locations represent a nomadic tribe on the move; more likely they represent more than one group of Persians. What is reasonably clear from the cuneiform sources is that these Medes and Persians (and no doubt other Iranian peoples not identified by name) were moving into western Iran from the east. They probably followed routes along the southern face of the Elburz Mountains and, as they entered the Zagros, spread out to the northwest and southeast following the natural topography of the mountains. Where they could, they infiltrated farther west—for example, along the major pass across the mountains from Hamadān to Kermānshāh. In doing so, they met resistance from the local settled populations, who often appealed to Urartu, Assyria, and Elam for assistance in holding back the newcomers. Such appeals were, of course, most welcome to these great powers, who were willing to take advantage of the situation both to advance their interests at each other’s expense and to control the Iranian threat to themselves.

It has been suggested that the introduction of gray and gray-black pottery into western Iran from the northeast, which signals the start of the Iron Age, is the archaeological manifestation of this pattern of a gradual movement of Iranians from east to west. The case is by no means proved, but it is a reasonable reading of the combined evidence. If it is so, then the earliest Iranians in the Zagros Mountains can be dated to Iron Age I times, about 1300 bc. Archaeologically, the culture of Iron Age II times can be seen as having evolved out of that of the Iron Age I period, and, though the development is less clear, the same can be said of the relationship between the cultures of Iron Age II and III. The spread of the Iron Age I and II cultures in the Zagros is restricted and would appear to correspond fairly well with the distribution of Iranians known from the written documents. The distribution of the Iron Age III culture, on the other hand, is, at least by the 7th century bc, much more widespread and covers almost the whole of the Zagros. Thus, the argument that links these archaeological patterns with the Iranian migration into the area associates the Iron Age I and II cultures with the early penetration of the Iranians into the more eastern Zagros and with their infiltration westward along the major routes crosscutting the main mountain alignments. Those areas where traces of the Iron Age I and II cultures do not appear were the regions still under the control of non-Iranian indigenous groups supported by Urartu, Assyria, and Elam. The widespread Iron Age III culture is then associated with the rise to power of the Median kingdom in the 7th and early 6th centuries bc and the Iranianization of the whole of the Zagros Mountains.
