Elam (//; Linear Elamite:
Elam was part of the early urbanization during the Chalcolithic period (Copper Age). The emergence of written records from around 3000 BC also parallels Sumerian history, where slightly earlier records have been found. In the Old Elamite period (Middle Bronze Age), Elam consisted of kingdoms on the Iranian plateau, centered in Anshan, and from the mid-2nd millennium BC, it was centered in Susa in the Khuzestan lowlands. Its culture played a crucial role during the Persian Achaemenid dynasty that succeeded Elam, when the Elamite language remained among those in official use. Elamite is generally considered a language isolate unrelated to any other languages. In accordance with geographical and archaeological matches, some historians argue that the Elamites comprise a large portion of the ancestors of the modern day Lurs whose language, Luri, split from Middle Persian.

In prehistory, Elam was centered primarily in modern Khuzestān and Ilam. The name Khuzestān is derived ultimately from Old Persian: 𐎢𐎺𐎩 (hūja) meaning Susa/Elam. This became Middle Persian: 𐭧𐭥𐭰 (hūz) "Susiana", and in modern Persian: خوز (xuz), compounded with the toponymic suffix -stån "place".

In geographical terms, Susiana basically represents the Iranian province of Khuzestan around the river Karun. In ancient times, several names were used to describe this area. The great ancient geographer Ptolemy was the earliest to call the area Susiana, referring to the country around Susa.
Disagreements over the location also exist in the Jewish historical sources says Daniel T. Potts. Some ancient sources draw a distinction between Elam as the highland area of Khuzestan, and Susiana as the lowland area. Yet in other ancient sources 'Elam' and 'Susiana' seem equivalent.
The uncertainty in this area extends also to modern scholarship. Since the discovery of ancient Anshan, and the realization of its great importance in Elamite history, the definitions were changed again. Some modern scholars argued that the centre of Elam lay at Anshan and in the highlands around it, and not at Susa in lowland Khuzistan.
Potts disagrees suggesting that the term 'Elam' was primarily constructed by the Mesopotamians to describe the area in general terms, without referring specifically either to the lowlanders or the highlanders,
"Elam is not an Iranian term and has no relationship to the conception which the peoples of highland Iran had of themselves. They were Anshanites, Marhashians, Shimashkians, Zabshalians, Sherihumians, Awanites, etc. That Anshan played a leading role in the political affairs of the various highland groups inhabiting southwestern Iran is clear. But to argue that Anshan is coterminous with Elam is to misunderstand the artificiality and indeed the alienness of Elam as a construct imposed from without on the peoples of the southwestern highlands of the Zagros mountain range, the coast of Fars and the alluvial plain drained by the Karun-Karkheh river system.

Knowledge of Elamite history remains largely fragmentary, reconstruction being based on mainly Mesopotamian (Sumerian, Akkadian, Assyrian and Babylonian) sources. The history of Elam is conventionally divided into three periods, spanning more than two millennia. The period before the first Elamite period is known as the proto-Elamite period:
- Proto-Elamite: c. 3200 – c. 2700 BC (Proto-Elamite script in Susa)
- Old Elamite period: c. 2700 – c. 1500 BC (earliest documents until the Sukkalmah Dynasty)
- Middle Elamite period: c. 1500 – c. 1100 BC (Anzanite dynasty until the Babylonian invasion of Susa)
- Neo-Elamite period: c. 1100 – 540 BC (characterized Assyrian and Median influence. 539 BC marks the beginning of the Achaemenid period.)
Proto-Elamite (c. 3200 – c. 2700 BC)
Proto-Elamite civilization grew up east of the Tigris and Euphrates alluvial plains; it was a combination of the lowlands and the immediate highland areas to the north and east. At least three proto-Elamite states merged to form Elam: Anshan (modern Fars Province), Awan (modern Lorestan Province) and Shimashki (modern Kerman). References to Awan are generally older than those to Anshan, and some scholars suggest that both states encompassed the same territory, in different eras (see Hanson, Encyclopædia Iranica). To this core Shushiana (modern Khuzestan) was periodically annexed and broken off. In addition, some Proto-Elamite sites are found well outside this area, spread out on the Iranian plateau; such as Warakshe, Sialk (now a suburb of the modern city of Kashan) and Jiroft in Kerman Province. The state of Elam was formed from these lesser states as a response to invasion from Sumer during the Old Elamite period. Elamite strength was based on an ability to hold these various areas together under a coordinated government that permitted the maximum interchange of the natural resources unique to each region. Traditionally, this was done through a federated governmental structure.
The Proto-Elamite city of Susa was founded around 4000 BC in the watershed of the river Karun. It is considered to be the site of Proto-Elamite cultural formation. During its early history, it fluctuated between submission to Mesopotamian and Elamite power. The earliest levels (22—17 in the excavations conducted by Le Brun, 1978) exhibit pottery that has no equivalent in Mesopotamia, but for the succeeding period, the excavated material allows identification with the culture of Sumer of the Uruk period. Proto-Elamite influence from the Mesopotamia in Susa becomes visible from about 3200 BC, and texts in the still undeciphered Proto-Elamite writing system continue to be present until about 2700 BC. The Proto-Elamite period ends with the establishment of the Awan dynasty. The earliest known historical figure connected with Elam is the king Enmebaragesi of Kish (c. 2650 BC?), who subdued it, according to the Sumerian king list. Elamite history can only be traced from records dating to beginning of the Akkadian Empire (2335–2154 BC) onwards.
In ancient Luristan, bronze-making tradition goes back to the mid-3rd millennium BC, and has many Elamite connections. Bronze objects from several cemeteries in the region date to the Early Dynastic Period (Mesopotamia) I, and to Ur-III period c. 2900–2000 BC. These excavations include Kalleh Nisar, Bani Surmah, Chigha Sabz, Kamtarlan, Sardant, and Gulal-i Galbi.
Old Elamite period (c. 2700 – c. 1500 BC)
The Old Elamite period began around 2700 BC. Historical records mention the conquest of Elam by Enmebaragesi, the Sumerian king of Kish in Mesopotamia. Three dynasties ruled during this period. Twelve kings of each of the first two dynasties, those of Awan (or Avan; c. 2400 – c. 2100 BC) and Simashki (c. 2100 – c. 1970 BC), are known from a list from Susa dating to the Old Babylonian period. Two Elamite dynasties said to have exercised brief control over parts of Sumer in very early times include Awan and Hamazi; and likewise, several of the stronger Sumerian rulers, such as Eannatum of Lagash and Lugal-anne-mundu of Adab, are recorded as temporarily dominating Elam.
The Awan dynasty (2350–2150 BC) was partly contemporary with that of the Mesopotamian emperor Sargon of Akkad, who not only defeated the Awan king Luh-ishan and subjected Susa, but attempted to make the East Semitic Akkadian the official language there. From this time, Mesopotamian sources concerning Elam become more frequent, since the Mesopotamians had developed an interest in resources (such as wood, stone, and metal) from the Iranian plateau, and military expeditions to the area became more common. With the collapse of Akkad under Sargon's great great-grandson, Shar-kali-sharri, Elam declared independence under the last Awan king, Kutik-Inshushinak (c. 2240 – c. 2220 BC), and threw off the Akkadian language, promoting in its place the brief Linear Elamite script. Kutik-Inshushinnak conquered Susa and Anshan, and seems to have achieved some sort of political unity. Following his reign, the Awan dynasty collapsed as Elam was temporarily overrun by the Guti, another pre-Iranic people from what is now north west Iran who also spoke a language isolate.
About a century later, the Sumerian king Shulgi of the Neo-Sumerian Empire retook the city of Susa and the surrounding region. During the first part of the rule of the Simashki dynasty, Elam was under intermittent attack from the Sumerians of Mesopotamia and also Gutians from northwestern Iran, alternating with periods of peace and diplomatic approaches. The Elamite state of Simashki at this time also extended into northern Iran, and possibly even as far as the Caspian Sea. Shu-Sin of Ur gave one of his daughters in marriage to a prince of Anshan. But the power of the Sumerians was waning; Ibbi-Sin in the 21st century did not manage to penetrate far into Elam, and in 2004 BC, the Elamites, allied with the people of Susa and led by king Kindattu, the sixth king of Simashki, managed to sack Ur and lead Ibbi-Sin into captivity, ending the third dynasty of Ur. The Akkadian kings of Isin, successor state to Ur, managed to drive the Elamites out of Ur, rebuild the city, and to return the statue of Nanna that the Elamites had plundered.
The succeeding dynasty, often called the Sukkalmah dynasty (c. 1970 – c. 1770 BC) after "Great regents", the title borne by its members, also called the Epartid dynasty after the name of its founder Ebarat/ Eparti, was roughly contemporary with the Old Assyrian Empire, and Old Babylonian period in Mesopotamia, being younger by approximately sixty years than the Akkadian speaking Old Assyrian Empire in Upper Mesopotamia, and almost seventy-five years older than the Old Babylonian Empire. This period is confusing and difficult to reconstruct. It was apparently founded by Eparti I. During this time, Susa was under Elamite control, but Akkadian speaking Mesopotamian states such as Larsa and Isin continually tried to retake the city. Around 1850 BC Kudur-mabuk, apparently king of another Akkadian state to the north of Larsa, managed to install his son, Warad-Sin, on the throne of Larsa, and Warad-Sin's brother, Rim-Sin, succeeded him and conquered much of southern Mesopotamia for Larsa.
Notable Eparti dynasty rulers in Elam during this time include Sirukdukh (c. 1850 BC), who entered various military coalitions to contain the power of the south Mesopotamian states; Siwe-Palar-Khuppak, who for some time was the most powerful person in the area, respectfully addressed as "Father" by Mesopotamian kings such as Zimrilim of Mari, Shamshi-Adad I of Assyria, and even Hammurabi of Babylon; and Kudur-Nahhunte, who plundered the temples of southern Mesopotamia, the north being under the control of the Old Assyrian Empire. But Elamite influence in southern Mesopotamia did not last. Around 1760 BC, Hammurabi drove out the Elamites, overthrew Rim-Sin of Larsa, and established a short lived Babylonian Empire in Mesopotamia. Little is known about the latter part of this dynasty, since sources again become sparse with the Kassite rule of Babylon (from c. 1595 BC).
Trade with the Indus Valley civilization
Many archaeological finds suggest that maritime trade along the shores of Africa and Asia started several millennia ago. Trade between the Indus Valley Civilization and the cities of Mesopotamia and Elam, can be inferred from numerous find of Indus artifacts, particularly in the excavation as Susa. Various objects made with shell species that are characteristic of the Indus coast, particularly Trubinella Pyrum and Fasciolaria Trapezium, have been found in the archaeological sites of Mesopotamia and Susa dating from around 2500–2000 BC. Carnelian beads from the Indus were found in Susa in the excavation of the tell of the citadel. In particular, carnelian beads with an etched design in white were probably imported from the Indus Valley, and made according to a technique of acid-etching developed by the Harappans.
Exchanges seem to have waned after 1900 BC, together with the disappearance of the Indus valley civilization.
Indus bracelet made of Fasciolaria Trapezium or Turbinella pyrum imported to Susa in 2600–1700 BC. Found in the tell of the Susa acropolis. Louvre Museum, reference Sb 14473. This type of bracelet was manufactured in Mohenjo-daro, Lothal and Balakot. It is engraved with a chevron design which is characteristic of all shell bangles of the Indus Valley, visible here.
Middle Elamite period (c. 1500 – c. 1100 BC)
Anshan and Susa
The Middle Elamite period began with the rise of the Anshanite dynasties around 1500 BC. Their rule was characterized by an "Elamisation" of Susa, and the kings took the title "king of Anshan and Susa". While the first of these dynasties, the Kidinuids continued to use the Akkadian language frequently in their inscriptions, the succeeding Igihalkids and Shutrukids used Elamite with increasing regularity. Likewise, Elamite language and culture grew in importance in Susiana. The Kidinuids (c. 1500 – 1400 BC) are a group of five rulers of uncertain affiliation. They are identified by their use of the older title, "king of Susa and of Anshan", and by calling themselves "servant of Kirwashir", an Elamite deity, thereby introducing the pantheon of the highlands to Susiana. The city of Susa itself is one of the oldest in the world dating back to around 4200 BC. Since its founding Susa was known as a central power location for the Elamites and for later Persian dynasties. Susa's power would peak during the Middle Elamite period, when it would be the region's capital.
Of the Igehalkids (c. 1400 – 1210 BC), ten rulers are known, though their number was possibly larger. Some of them married Kassite princesses. The Kassites were also a Language Isolate speaking people from the Zagros Mountains who had taken Babylonia shortly after its sacking by the Hittite Empire in 1595 BC. The Kassite king of Babylon Kurigalzu II who had been installed on the throne by Ashur-uballit I of the Middle Assyrian Empire (1366–1020 BC), temporarily occupied Elam around 1320 BC, and later (c. 1230 BC) another Kassite king, Kashtiliash IV, fought Elam unsuccessfully. Kassite-Babylonian power waned, as they became dominated by the northern Mesopotamian Middle Assyrian Empire. Kiddin-Khutran of Elam repulsed the Kassites by defeating Enlil-nadin-shumi in 1224 BC and Adad-shuma-iddina around 1222–1217 BC. Under the Igehalkids, Akkadian inscriptions were rare, and Elamite highland gods became firmly established in Susa.
Under the Shutrukids (c. 1210 – 1100 BC), the Elamite empire reached the height of its power. Shutruk-Nakhkhunte and his three sons, Kutir-Nakhkhunte II, Shilhak-In-Shushinak, and Khutelutush-In-Shushinak were capable of frequent military campaigns into Kassite Babylonia (which was also being ravaged by the empire of Assyria during this period), and at the same time were exhibiting vigorous construction activity—building and restoring luxurious temples in Susa and across their Empire. Shutruk-Nakhkhunte raided Babylonia, carrying home to Susa trophies like the statues of Marduk and Manishtushu, the Manishtushu Obelisk, the Stele of Hammurabi and the stele of Naram-Sin. In 1158 BC, after much of Babylonia had been annexed by Ashur-Dan I of Assyria and Shutruk-Nakhkhunte, the Elamites defeated the Kassites permanently, killing the Kassite king of Babylon, Zababa-shuma-iddin, and replacing him with his eldest son, Kutir-Nakhkhunte, who held it no more than three years before being ejected by the native Akkadian speaking Babylonians. The Elamites then briefly came into conflict with Assyria, managing to take the Assyrian city of Arrapha (modern Kirkuk) before being ultimately defeated and having a treaty forced upon them by Ashur-Dan I.
Kutir-Nakhkhunte's son Khutelutush-In-Shushinak was probably of an incestuous relation of Kutir-Nakhkhunte's with his own daughter, Nakhkhunte-utu. He was defeated by Nebuchadnezzar I of Babylon, who sacked Susa and returned the statue of Marduk, but who was then himself defeated by the Assyrian king Ashur-resh-ishi I. He fled to Anshan, but later returned to Susa, and his brother Shilhana-Hamru-Lagamar may have succeeded him as last king of the Shutrukid dynasty. Following Khutelutush-In-Shushinak, the power of the Elamite empire began to wane seriously, for after the death of this ruler, Elam disappears into obscurity for more than three centuries.
Neo-Elamite period (c. 1100 – 540 BC)
Neo-Elamite I (c. 1100 – c. 770 BC)
Very little is known of this period. Anshan was still at least partially Elamite. There appear to have been unsuccessful alliances of Elamites, Babylonians, Chaldeans and other peoples against the powerful Neo Assyrian Empire (911–605 BC); the Babylonian king Mar-biti-apla-ushur (984–979 BC) was of Elamite origin, and Elamites are recorded to have fought unsuccessfully with the Babylonian king Marduk-balassu-iqbi against the Assyrian forces under Shamshi-Adad V (823–811 BC).
Neo-Elamite II (c. 770 – 646 BC)
The later Neo-Elamite period is characterized by a significant migration of Indo-European speaking Iranians to the Iranian plateau. Assyrian sources beginning around 800 BC distinguish the "powerful Medes", i.e. the actual Medes, Persians, Parthians, Sagartians, Margians, Bactrians, Sogdians etc.. Among these pressuring tribes were the Parsu, first recorded in 844 BC as living on the southeastern shore of Lake Urmiah, but who by the end of this period would cause the Elamites' original home, the Iranian Plateau, to be renamed Persia proper. These newly arrived Iranian peoples were also conquered by Assyria, and largely regarded as vassals of the Neo-Assyrian Empire until the late 7th century.
More details are known from the late 8th century BC, when the Elamites were allied with the Chaldean chieftain Merodach-baladan to defend the cause of Babylonian independence from Assyria. Khumbanigash (743–717 BC) supported Merodach-baladan against Sargon II, apparently without success; while his successor, Shutruk-Nakhkhunte II (716–699 BC), was routed by Sargon's troops during an expedition in 710, and another Elamite defeat by Sargon's troops is recorded for 708. The Assyrian dominion over Babylon was underlined by Sargon's son Sennacherib, who defeated the Elamites, Chaldeans and Babylonians and dethroned Merodach-baladan for a second time, installing his own son Ashur-nadin-shumi on the Babylonian throne in 700.
Shutruk-Nakhkhunte II, the last Elamite to claim the old title "king of Anshan and Susa", was murdered by his brother Khallushu, who managed to briefly capture the Assyrian governor of Babylonia Ashur-nadin-shumi and the city of Babylon in 694 BC. Sennacherib soon responded by invading and ravaging Elam. Khallushu was in turn assassinated by Kutir-Nakhkhunte, who succeeded him but soon abdicated in favor of Khumma-Menanu III (692–689 BC). Khumma-Menanu recruited a new army to help the Babylonians and Chaldeans against the Assyrians at the battle of Halule in 691. Both sides claimed the victory in their annals, but Babylon was destroyed by Sennacherib only two years later, and its Elamite allies defeated in the process.
The reigns of Khumma-Khaldash I (688–681 BC) and Khumma-Khaldash II (680–675 BC) saw a deterioration of Elamite-Babylonian relations, and both of them raided Sippar. At the beginning of Esarhaddon's reign in Assyria (681–669 BC), Nabu-zer-kitti-lišir, an ethnically Elamite governor in the south of Babylonia, revolted and besieged Ur, but was routed by the Assyrians and fled to Elam where the king of Elam, fearing Assyrian repercussions, took him prisoner and put him to the sword.
Urtaku (674–664 BC) for some time wisely maintained good relations with the Assyrian king Ashurbanipal (668–627 BC), who sent wheat to Susiana during a famine. But these friendly relations were only temporary, and Urtaku was killed in battle during a failed Elamite attack on Assyria.
His successor Tempti-Khumma-In-Shushinak (664–653 BC) attacked Assyria, but was defeated and killed by Ashurbanipal following the battle of the Ulaï in 653 BC; and Susa itself was sacked and occupied by the Assyrians. In this same year the Assyrian vassal Median state to the north fell to the invading Scythians and Cimmerians under Madius, and displacing another Assyrian vassal people, the Parsu (Persians) to Anshan which their king Teispes captured that same year, turning it for the first time into an Indo-Iranian kingdom under Assyrian dominance that would a century later become the nucleus of the Achaemenid dynasty. The Assyrians successfully subjugated and drove the Scythians and Cimmerians from their Iranian colonies, and the Persians, Medes and Parthians remained vassals of Assyria.
During a brief respite provided by the civil war between Ashurbanipal and his own brother Shamash-shum-ukin whom their father Esarhaddon had installed as the vassal king of Babylon, the Elamites both gave support to Shamash-shum-ukin, and indulged in fighting among themselves, so weakening the Elamite kingdom that in 646 BC Ashurbanipal devastated Susiana with ease, and sacked Susa. A succession of brief reigns continued in Elam from 651 to 640, each of them ended either due to usurpation, or because of capture of their king by the Assyrians. In this manner, the last Elamite king, Khumma-Khaldash III, was captured in 640 BC by Ashurbanipal, who annexed and destroyed the country.
In a tablet unearthed in 1854 by Henry Austin Layard, Ashurbanipal boasts of the destruction he had wrought:
Susa, the great holy city, abode of their Gods, seat of their mysteries, I conquered. I entered its palaces, I opened their treasuries where silver and gold, goods and wealth were amassed … I destroyed the ziggurat of Susa. I smashed its shining copper horns. I reduced the temples of Elam to naught; their gods and goddesses I scattered to the winds. The tombs of their ancient and recent kings I devastated, I exposed to the sun, and I carried away their bones toward the land of Ashur. I devastated the provinces of Elam and on their lands I sowed salt.
Neo-Elamite III (646–539 BC)
The devastation was a little less complete than Ashurbanipal boasted, and a weak and fragmented Elamite rule was resurrected soon after with Shuttir-Nakhkhunte, son of Humban-umena III (not to be confused with Shuttir-Nakhkhunte, son of Indada, a petty king in the first half of the 6th century). Elamite royalty in the final century preceding the Achaemenids was fragmented among different small kingdoms, the united Elamite nation having been destroyed and colonised by the Assyrians. The three kings at the close of the 7th century (Shuttir-Nakhkhunte, Khallutush-In-Shushinak and Atta-Khumma-In-Shushinak) still called themselves "king of Anzan and of Susa" or "enlarger of the kingdom of Anzan and of Susa", at a time when the Achaemenid Persians were already ruling Anshan under Assyrian dominance.
The various Assyrian Empires, which had been the dominant force in the Near East, Asia Minor, the Caucasus, North Africa, Arabian peninsula and East Mediterranean for much of the period from the first half of the 14th century BC, began to unravel after the death of Ashurbanipal in 627 BC, descending into a series of bitter internal civil wars which also spread to Babylonia. The Iranian Medes, Parthians, Persians and Sagartians, who had been largely subject to Assyria since their arrival in the region around 1000 BC, quietly took full advantage of the anarchy in Assyria, and in 616 BC freed themselves from Assyrian rule.
The Medians took control of Elam during this period. Cyaxares the king of the Medes, Persians, Parthians and Sagartians entered into an alliance with a coalition of fellow former vassals of Assyria, including Nabopolassar of Babylon and Chaldea, and also the Scythians and Cimmerians, against Sin-shar-ishkun of Assyria, who was faced with unremitting civil war in Assyria itself. This alliance then attacked a disunited and war weakened Assyria, and between 616 BC and 599 BC at the very latest, had conquered its vast empire which stretched from the Caucasus Mountains to Egypt, Libya and the Arabian Peninsula, and from Cyprus and Ephesus to Persia and the Caspian Sea.
The major cities in Assyria itself were gradually taken; Arrapha (modern Kirkuk) and Kalhu (modern Nimrud) in 616 BC, Ashur, Dur-Sharrukin and Arbela (modern Erbil) in 613, Nineveh falling in 612, Harran in 608 BC, Carchemish in 605 BC, and finally Dur-Katlimmu by 599 BC. Elam, already largely destroyed and subjugated by Assyria, thus became easy prey for the Median dominated Iranian peoples, and was incorporated into the Median Empire (612–546 BC) and then the succeeding Achaemenid Empire (546–332 BC), with Assyria suffering the same fate. (see Achaemenid Assyria, Athura).
The prophet Ezekiel describes the status of their power in the 12th year of the Hebrew Babylonian Captivity in 587 BCE:
There is Elam and all her multitude, All around her grave, All of them slain, fallen by the sword, Who have gone down uncircumcised to the lower parts of the earth, Who caused their terror in the land of the living; Now they bear their shame with those who go down to the Pit. (Ezekiel 32:24)
Their successors Khumma-Menanu and Shilhak-In-Shushinak II bore the simple title "king", and the final king Tempti-Khumma-In-Shushinak used no honorific at all. In 540 BC, Achaemenid rule began in Susa.
Elymais (187 BC - 224 AD)
Elymaïs was the location of the death of Antiochus III the Great who was killed while pillaging a temple of Bel in 187 BC. Following the rise and fall of the Achaemenid Empire and the Seleucid Empire, a new dynasty of Elamite rulers established Elymais from 147 BC to 224 AD, usually under the suzerainty of the Parthian Empire, until the advent of the unified Sasanian Empire in 224 AD.
