Zagros Mountains in the context of "Iranian Plateau"

The Iranian plateau or Persian plateau is a geological feature spanning parts of the Caucasus, Central Asia, South Asia, and West Asia. It makes up part of the Eurasian plate, and is wedged between the Arabian plate and the Indian plate. The plateau is situated between the Zagros Mountains to the west, the Caspian Sea and the Köpet Dag to the north, the Armenian Highlands and the Caucasus Mountains to the northwest, the Strait of Hormuz and the Persian Gulf to the south, and the Indian subcontinent to the southeast.

As a historical region, it includes Parthia, Media, Persis, and some of the previous territories of Greater Iran. The Zagros form the plateau's western boundary, and its eastern slopes may also be included in the term. The Encyclopædia Britannica excludes "lowland Khuzestan" explicitly and characterizes Elam as spanning "the region from the Mesopotamian plain to the Iranian Plateau".

Media (Old Persian: 𐎶𐎠𐎭 Māda; Greek: Μηδία Mēdía; Akkadian: Mādāya) was a political entity centered in Ecbatana that existed from the 7th century BCE until the mid-6th century BCE and is believed to have dominated a significant portion of the Iranian plateau, preceding the powerful Achaemenid Empire. The frequent interference of the Assyrians in the Zagros region led to the process of unifying the Median tribes. By 612 BCE, the Medes became strong enough to overthrow the declining Assyrian empire in alliance with the Babylonians. However, contemporary scholarship tends to be skeptical about the existence of a united Median kingdom or state, at least for most of the 7th century BCE.

According to classical historiography, Media emerged as one major power of the ancient Near East after the collapse of Assyria. Under Cyaxares (r. 625–585 BCE), the kingdom's borders were expanded to the east and west through the subjugation of neighboring peoples, such as the Persians and Armenians. Media's territorial expansion led to the formation of the first Iranian empire, which at its height would have exercised authority over more than two million square kilometers, stretching from the eastern banks of the Halys River in Anatolia to Central Asia. In this period, the Median empire was one of the great powers in the ancient Near East alongside Babylon, Lydia, and Egypt. During his reign, Astyages (r. 585–550 BCE) worked to strengthen and centralize the Median state, going against the will of tribal nobility, which may have contributed to the kingdom's downfall. In 550 BCE, the Median capital, Ecbatana, was conquered by the Persian king Cyrus II, marking the beginning of the Achaemenid empire.

The Arabian plate is a minor tectonic plate in the Northern and Eastern Hemispheres.

It is one of the three continental plates (along with the African and Indian plates) that have been moving northward in geological history and colliding with the Eurasian plate. This collision is resulting in a mingling of plate pieces and mountain ranges extending in the west from the Pyrenees, crossing Southern Europe to Iranian plateau, forming the Alborz and the Zagros Mountains, to the Himalayas and ranges of Southeast Asia.

The Tigris–Euphrates river system is a large river system in West Asia that flows into the Persian Gulf. Its primary rivers are the Tigris and Euphrates, along with smaller tributaries.

From their sources and upper courses in the Armenian highlands of eastern Turkey, being Lake Hazar for the Tigris and Karasu along with the Murat River for the Euphrates, the two rivers descend through valleys and gorges to the uplands of Syria and northern Iraq and then to the alluvial plain of central Iraq. Other tributaries join the Tigris from sources in the Zagros Mountains to the east. The rivers flow in a south-easterly direction through the central plain and combine at Al-Qurnah to form the Shatt al-Arab and discharge into the Persian Gulf. The rivers and their tributaries drain an area of 879,790 square kilometres (339,690 sq mi), including almost the entire area of Iraq as well as portions of Turkey, Syria, Iran and Kuwait.

The prehistory of Mesopotamia is the period between the Paleolithic and the emergence of writing in the area of the Fertile Crescent around the Tigris and Euphrates rivers, as well as surrounding areas such as the Zagros foothills, southeastern Anatolia, and northwestern Syria.

In general, Paleolithic Mesopotamia is poorly documented, with the situation worsening in southern Mesopotamia for periods prior to the 4th millennium BC. Geological conditions meant that most of the remains were buried under a thick layer of alluvium or submerged beneath the waters of the Persian Gulf. The Middle Paleolithic witnessed the emergence of a population of hunter-gatherers who lived in the caves of the Zagros and, seasonally, in numerous open-air sites. They were producers of a lithic industry of the Mousterian type, and their funerary remains, found in the cave of Shanidar, indicate the existence of solidarity and the practice of healing between the members of a group. During the Upper Paleolithic, the Zagros was probably occupied by modern man. The Shanidar cave contains only tools made of bone or antler, typical of a local Aurignacian called "Baradostian" by specialists.

Persepolis was the ceremonial capital of the Achaemenid Empire (c. 550–330 BC). It is situated in the plains of Marvdasht, encircled by the southern Zagros Mountains, Fars province of Iran. It is one of the key Iranian cultural heritage sites and a UNESCO World Heritage Site.

The earliest remains of Persepolis date back to 515 BC. The city, acting as a major center for the empire, housed a palace complex and citadel designed to serve as the focal point for governance and ceremonial activities. It exemplifies the Achaemenid style of architecture. The complex was taken by the army of Alexander the Great in 330 BC, and soon after, its wooden parts were completely destroyed by fire. According to one theory Alexander deliberately set fire to Persepolis to avenge the destruction of Athens by the Persians, second theory is that it was at the urging of Thaïs, a courtesan, during a feast when Alexander was intoxicated.

The Cedar Forest (𒄑𒂞𒄑𒌁giš eren giš tir) is the glorious realm of the gods of Mesopotamian mythology. It is guarded by the demigod Humbaba and was once entered by the hero Gilgamesh who dared cut down cedar trees from its virgin stands during his quest for fame. The Cedar Forest is described in Tablets 4–6 of the Epic of Gilgamesh. Earlier descriptions come from the Ur III poem Gilgamesh and Huwawa.

The Sumerian poems of his deeds say that Gilgamesh traveled east, presumably, to the Zagros Mountains of Iran (ancient Elam) to the cedar forest, yet the later more extensive Babylonian examples place the cedar forests west in Lebanon.

The Old Assyrian period was the second stage of Assyrian history, covering the history of the city of Assur from its rise as an independent city-state under Puzur-Ashur I c. 2025 BC to the foundation of a larger Assyrian territorial state after the accession of Ashur-uballit I c. 1363 BC, which marks the beginning of the succeeding Middle Assyrian period. The Old Assyrian period is marked by the earliest known evidence of the development of a distinct Assyrian culture, separate from that of southern Mesopotamia and was a geopolitically turbulent time when Assur several times fell under the control or suzerainty of foreign kingdoms and empires. The period is also marked with the emergence of a distinct Assyrian dialect of the Akkadian language, a native Assyrian calendar and Assur for a time becoming a prominent site for international trade.

For most of the Old Assyrian period, Assur was a minor city-state with little political and military influence. In contrast to Assyrian kings of later periods, the kings in the Old Assyrian period were just one of the prominent leading officials in the city's administration and normally used the style Išši'ak Aššur, which translates to "governor (on behalf) of (the god) Ashur", rather than šar (king). The kings presided over the city's actual administrative body, the Ālum (city assembly), which was made up of prominent and influential members among Assur's populace. Though lacking in military and political might, Assur was an important economic center in northern Mesopotamia. From the time of Erishum I (c. 1974–1935 BC) until the late 19th century BC, the city was a hub in a large trading network that spanned from the Zagros Mountains in the east to central Anatolia in the west. During their time as prominent traders the Assyrians founded a number of trading colonies at various sites in the trading network, such as Kültepe.
