Lake Urmia in the context of "Mannae"

The History of Iran (also known as Persia) is intertwined with Greater Iran, which is a region encompassing all of the areas that have witnessed significant settlement or influence by the Iranian peoples and the Iranian languages – chiefly the Persians and the Persian language. Central to this region is the Iranian plateau, now largely covered by modern Iran. The most pronounced impact of Iranian history can be seen stretching from Anatolia in the west to the Indus Valley in the east, including the Levant, Mesopotamia, the Caucasus, and parts of Central Asia. It also overlaps or mingles with the histories of many other major civilizations, such as India, China, Greece, Rome, and Egypt.

Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to the 5th millennium BC. The Iranian plateau's western regions integrated into the rest of the ancient Near East with the Elamites (in Ilam and Khuzestan), the Kassites (in Kuhdesht), the Gutians (in Luristan), and later with other peoples like the Urartians (in Oshnavieh and Sardasht) near Lake Urmia and the Mannaeans (in Piranshahr, Saqqez and Bukan) in Kurdistan. German philosopher Georg Wilhelm Friedrich Hegel called the Persians the "first Historical People" in his Lectures on the Philosophy of World History. The sustained Iranian empire is understood to have begun with the rise of the Medes during the Iron Age, when Iran was unified as a nation under the Median kingdom in the 7th century BC. By 550 BC, the Medes were sidelined by the conquests of Cyrus the Great, who brought the Persians to power with the establishment of the Achaemenid Empire. Cyrus' ensuing campaigns enabled the Persian realm's expansion across most of West Asia and much of Central Asia, and his successors would eventually conquer parts of Southeast Europe and North Africa to preside over the largest empire the world had yet seen. In the 4th century BC, the Achaemenid Empire was conquered by the Macedonian Empire of Alexander the Great, whose death led to the establishment of the Seleucid Empire over the bulk of former Achaemenid territory. In the following century, Greek rule of the Iranian plateau came to an end with the rise of the Parthian Empire, which also conquered large parts of the Seleucids' Anatolian, Mesopotamian, and Central Asian holdings. While the Parthians were succeeded by the Sasanian Empire in the 2nd century, Iran remained a leading power for the next millennium, although the majority of this period was marked by the Roman–Persian Wars.

Nairi (Akkadian: 𒆳𒆳𒈾𒄿𒊑, romanized: mātāt [KUR.KUR] Na-i-ri, lit. 'Nairi lands', also Na-'i-ru; Armenian: Նաիրի) was the Akkadian name for a region inhabited by a particular group (possibly a confederation or league) of tribal principalities in the Armenian Highlands, approximately spanning the area between modern Diyarbakır and Lake Van and the region west of Lake Urmia. Nairi has sometimes been equated with Nihriya, known from Mesopotamian, Hittite, and Urartian sources. However, its co-occurrence with Nihriya within a single text may argue against this.

Prior to the Bronze Age collapse, the Nairi tribes were considered a force strong enough to contend with both Assyria and Hatti. If Nairi and Nihriya are to be identified, then the region was the site of the Battle of Nihriya (c. 1230 BCE), the culminating point of the hostilities between Hittites and Assyrians for control over the remnants of the former kingdom of Mitanni.

Urartu was an Iron Age kingdom centered around the Armenian highlands between Lake Van, Lake Urmia, and Lake Sevan. The territory of the ancient kingdom of Urartu extended over the modern frontiers of Turkey, Iran, Iraq, and Armenia. Its kings left behind cuneiform inscriptions in the Urartian language, a member of the Hurro-Urartian language family.

Urartu extended from the Euphrates in the west 850 km to the region west of Ardabil in Iran, and 500 km from Lake Çıldır near Ardahan in Turkey to the region of Rawandiz in Iraqi Kurdistan. The kingdom emerged in the mid-9th century BC and dominated the Armenian highlands in the 8th and 7th centuries BC. Urartu frequently warred with Assyria and became, for a time, the most powerful state in the Near East. Weakened by constant conflict, it was eventually conquered, either by the Iranian Medes in the early 6th century BC or by Cyrus the Great in the middle of the 6th century BC. Archaeologically, it is noted for its large fortresses and sophisticated metalwork.

Mannaea (/məˈniːə/, sometimes written as Mannea; Akkadian: Mannai, Biblical Hebrew: Minni (מנּי)) was an ancient kingdom that flourished in northwestern Iran, primarily south and southeast of Lake Urmia, during the early first millennium BCE, roughly from the 10th to the 7th century BCE. It developed into a prominent regional power along the northeastern frontier of the Neo-Assyrian Empire, situated between major neighbors like Urartu and a constellation of smaller buffer states, such as Zikirta and Musasir. The capital of Mannaea was likely at Izirtu, near modern-day Saqqez.

Mannaea played a key role in the shifting alliances between the Assyrian and Urartian empires, acting alternately as ally and adversary. Archaeological and textual evidence points to a complex society with fortified cities, regional governors, and a tributary economy. Although its exact ethno-linguistic identity remains uncertain, Assyrian sources suggest the Mannaeans spoke an unidentified language. Some scholars link it to the Hurro-Urartian family, while others, based on recent genetic evidence from Hasanlu Tepe, propose ties to Armenian or a distinct non-Indo-Iranian language.
