The Persians are an Iranian ethnic group that make up over half the population of Iran. They share a common cultural system and are native speakers of the Persian language, as well as closely related languages.
The ancient Persians were originally a nomadic branch of the ancient Iranian population who entered modern-day Iran by the early 10th century BC. Together with their compatriot allies, they established and ruled some of the world's most powerful empires, well-recognized for their massive cultural, political, and social influence covering much of the territory and population of the ancient world.
Throughout history, the Persians have contributed greatly to various forms of art, owning one of the world's most prominent literary traditions, and have made contributions in numerous other fields, including mathematics, Islamic theology, medicine and various sciences.
In contemporary terminology, people of Persian heritage native to present-day Afghanistan and Tajikistan are referred to as Tajiks; however, it is to be noted that Tajik and Persian were historically synonyms that were used interchangeably and many of the most influential Persian figures hailed from Khorasan, a historical region located mostly outside of Iran's present-day borders to the east.
The English term Persian derives from Latin Persia, itself deriving from Greek Persís (Περσίς), a Hellenized form of Old Persian Pārsa (𐎱𐎠𐎼𐎿). In the Bible, it is referred to as Parás (Hebrew: פָּרָס)—sometimes Paras uMadai (פרס ומדי; "Persia and Media")—within the books of Esther, Daniel, Ezra and Nehemya.
History of usage
Although Persis was originally one of the provinces of ancient Iran, varieties of this term (e.g. Persia) were adopted through Greek sources and used as an official name for all of Iran for many years. Thus, in the Western world, the term Persian came to refer to all inhabitants of the country.
Some medieval and early modern Islamic sources also used cognates of the term Persian to refer to various Iranian peoples, including the speakers of the Khwarezmian language, the Mazanderani language and the Old Azeri language. 10th-century Iraqi historian Al-Masudi refers to Pahlavi, Dari and Azari as dialects of the Persian language. In 1333, medieval Moroccan traveler and scholar Ibn Battuta, referred to the people of Kabul as a specific sub-tribe of Persians. Lady Mary (Leonora Woulfe) Sheil, in her observation of Iran during the Qajar era, describes Persians, Kurds and Leks to identify themselves as "descendants of the ancient Persians".
On March 21, 1935, the former king of Iran, Reza Shah Pahlavi, issued a decree asking the international community to use the term Iran, the native name of the country, in formal correspondence. However, the term Persian is still historically used to designate the predominant population of the Iranian peoples living in the Iranian cultural continent.
The earliest known written record attributed to the Persians is from the Black Obelisk of Shalmaneser III, an Assyrian inscription from the mid-9th century BC, found at Nimrud. The inscription mentions Parsua (presumed to mean "border" or "borderland") as a tribal chiefdom (860–600 BC) in modern-day western Iran.
The ancient Persians were originally a nomadic branch of the Iranian population that, in the early 10th century BC, settled to the northwest of modern-day Iran. They were initially dominated by the Assyrians for much of the first three centuries after arriving in the region; however, they played a major role in the downfall of the Neo-Assyrian Empire. The Medes, another branch of this population, founded the unified empire of Media as the region's dominant cultural and political power in c. 625 BC. Meanwhile, the Persian dynasty of the Achaemenids formed a vassal state to the central Median power. In c. 552 BC, the Achaemenids began a revolution which eventually led to the conquest of the empire by Cyrus II in c. 550 BC. They spread their influence to the rest of what is called the Iranian Plateau, and assimilated with the non-Iranian indigenous groups of the region, including the Elamites and Mannaeans.
At its greatest extent, the Achaemenid Empire stretched from parts of Eastern Europe in the west, to the Indus Valley in the east, making it the largest empire the world had yet seen. The Achaemenids developed the infrastructure to support their growing influence, including the creation of Pasargadae and the opulent city of Persepolis. The empire extended as far as the limits of the Greek city states in modern-day mainland Greece, where the Persians and Athenians influenced each other in what is essentially a reciprocal cultural exchange. Its legacy and impact on the kingdom of Macedon was also notably huge, even for centuries after the withdrawal of the Persians from Europe following the Greco-Persian Wars. The empire collapsed in 330 BC following the conquests of Alexander the Great, but reemerged shortly after as the Parthian Empire.
Until the Parthian era, the Iranian identity had an ethnic, linguistic, and religious value; however, it did not yet have a political import. Parthian, a mutually intelligible language with the Middle Persian language, became an official language of the Parthian Empire. It had influences on the modern Persian language, as well as a major influence on the neighboring Armenian language.
By the time of the Sassanian Empire, a national culture which was fully aware of being Iranian took shape, partially motivated by restoration and revival of the wisdom of "the old sages" (Middle Persian: dānāgān pēšēnīgān). Other aspects of this national culture included the glorification of a great heroic past and an archaizing spirit. Throughout the period, the Iranian identity reached its height in every aspect. Middle Persian, which is the immediate ancestor of Modern Persian and a variety of other Iranian dialects, became the official language of the empire and was greatly diffused among Iranians.
The Parthians and the Sassanids would also extensively interact with the Romans culturally. The Roman–Persian wars and the Byzantine–Sasanian wars would shape the landscape of Western Asia, Europe, the Caucasus, North Africa, and the Mediterranean Basin for centuries. For a period of over 400 years, the neighboring Byzantines and Sassanids were recognized as the two leading powers in the world.
The intermingling of Persians, Medes, Parthians, Bactrians and indigenous "pre-Iranian" people of Iran (including the Elamites) gained more ground, and a homogeneous Iranian identity was created to the extent that all were just called Iranians, irrespective of clannish affiliations and regional linguistic or dialectal alterities. Furthermore, the process of incomers' assimilation which had been started with the Greeks, continued in the face of Arab, Mongol and Turkic invasions and proceeded right up to Islamic times.
In modern-day Iran, Persians make up the majority of the population. They speak the western dialects and varieties of the modern Persian language, which also serves as the country's official language.
The Persian language and its various varieties are part of the Western group of the Iranian branch of the Indo-European language family. Modern Persian is classified as a continuation of Middle Persian, the official religious and literary language of the Sassanid Empire, itself a continuation of Old Persian, which was spoken by the time of the Achaemenid Empire.
Old Persian is one of the oldest Indo-European languages attested in original texts. Examples of Old Persian have been found in present-day Iran, Armenia, Romania (Gherla), Iraq, Turkey, and Egypt. The oldest attested text written in Old Persian is from the Behistun Inscription.
There are several ethnic groups and communities which are either ethnically or linguistically related to the Persian people, living within various regions of modern-day Iran, the Caucasus, Tajikistan, Afghanistan, Turkey, Iraq, and the Persian Gulf states.
The Lurish people, living primarily in the western regions of Iran, are an ethnic Iranian people often associated with Persians and Kurds. They speak various dialects of the Lurish language, which are closely related to the Middle Persian language.
Concentrated in Azerbaijan, Armenia and Russia (Dagestan), the Caucasian Tat people are another ethnic Iranian people whose mother tongue—the Tat language—is considered a variant of the Persian language. Their origin is traced to the merchants who settled in the region by the time of the Sassanid Empire.
The Hazaras, making up the third largest ethnic group in Afghanistan, are a Persian-speaking people speaking a variety of Persian called Hazaragi, which is more precisely a part of the Dari dialect continuum (one of the two main languages of Afghanistan), and is mutually intelligible with Dari.
The Aimaqs are a semi-nomadic Persian-speaking people found mostly in western Afghanistan. They mainly speak a variety of Persian called Aimaq, which is close to the Khorasani and Dari varieties.
From the early inhabitants of Persis, to the Achaemenid, Parthian, and Sassanid empires, to the neighbouring Greek city states, the kingdom of Macedon, the caliphates and the Islamic world, all the way to the modern day Iran and Western Europe, and such far places as those found in India, Asia, and Indonesia, Persian culture has been either recognized, incorporated, adopted or celebrated. This is due mainly to geopolitical conditions, and its intricate relationship with the ever-changing political arena once as dominant as the Achaemenid Empire.
The artistic heritage of the Persians is eclectic, and includes major contributions from both the east and the west. Persian art borrowed heavily from the indigenous Elamite civilization and Mesopotamia, and later from the Hellenistic civilization. In addition, due to the somewhat central location of Iran, it has served as a fusion point between eastern and western traditions.
Persians have contributed in various forms of art, including carpet-waving, calligraphy, miniature-painting, illustrated manuscripts, glasswork, lacquer-work, khatam (a native form of marquetry), metalwork, pottery, mosaic, and textile design.
The Persian language is known to have one of the world's oldest and most powerful literatures, with prominent medieval poets such as Ferdowsi (author of Šāhnāme, Iran's national epic), Rudaki, Rumi, Hafez Shirazi, Saadi Shirazi, Nizami Ganjavi, Omar Khayyam and Attar of Nishapur.
Not all Persian literature is written in Persian, as some consider works written by Persians in other languages—such as Arabic and Greek—to be included. At the same time, not all literature written in Persian is written by ethnic Persians or Iranians, as Turkic, Caucasian and Indic poets and writers have also used the Persian language in the environment of Persianate cultures.
Prominent writers such as Sadegh Hedayat, Forough Farrokhzad, Ahmad Shamlou, Simin Daneshvar, Mehdi Akhavan-Sales and Parvin E'tesami have also had major contributions to contemporary Persian literature.
The most prominent examples of ancient Persian architecture are the work of the Achaemenids hailing from Persis. The quintessential feature of Achaemenid architecture was its eclectic nature, with elements from Median architecture, Assyrian architecture, and Asiatic Greek architecture all incorporated. Achaemenid architectural heritage, beginning with the expansion of the empire around 550 BC, was a period of artistic growth that left a legacy ranging from Cyrus the Great's solemn tomb at Pasargadae to the structures at Persepolis, and such historical sites as Naqsh-e Rustam.
During the Sassanid era, multiple architectural projects took place, some of which are still existing, including the Palace of Ardeshir, the Sarvestan Palace, the castle fortifications in Derbent (located in North Caucasus, now part of Russia), and the reliefs at Taq Bostan. The Bam Citadel, a massive structure at 1,940,000 square feet (180,000 m2) constructed on the Silk Road in Bam, is from around the 5th century BC.

Modern contemporary architectural projects influenced by the ancient Achaemenid architecture include the Tomb of Ferdowsi erected under the reign of Reza Shah in Tus, the Azadi Tower erected in 1971 at a square in Tehran, and the Dariush Grand Hotel located on Kish Island in the Persian Gulf.
"The Great King [Cyrus II]...in all the districts he resides in and visits, takes care that there are paradeisos ("paradise", from Avestan pairidaēza) as they [Persians] call them, full of the good and beautiful things that the soil produce."
For the Achaemenid monarchs, gardens assumed an important place. Persian gardens utilized the Achaemenid knowledge of water technologies, as they utilized aqueducts, earliest recorded gravity-fed water rills, and basins arranged in a geometric system. The enclosure of this symmetrically arranged planting and irrigation, by an infrastructure such as a building or a palace created the impression of "paradise". Parthians and Sassanids later added their own modifications to the original Achaemenid design. Later on, the quadripartite design (čārbāq) of Persian gardens was reinterpreted within the Muslim world.
Today, examples of these traditional gardens can be seen in such places as the Tomb of Hafez, Golshan Garden, Qavam House, Eram Garden, Shazdeh Garden, Fin Garden, Tabatabaei House, and the Borujerdis House.

According to the accounts reported by Xenophon, a great number of singers were present at the Achaemenid court. However, little information is available from the music of that era. The music scene of the Sasanian Empire has a more available and detailed documentation than the earlier periods, and is especially more evident within the context of Zoroastrian musical rituals. In general, Sasanian music was influential, and was later adopted in the subsequent eras.
Iranian music, as a whole, utilizes a variety of musical instruments that are unique to the region, and has remarkably evolved since the ancient and medieval times. In traditional Sassanid music, the octave was divided into seventeen tones. By the end of the 13th century, Iranian music also maintained a twelve interval octave, which resembled the western counterparts.
Traditional instruments used in Iranian music include the bowed spike-fiddle kamanche, the goblet drum tonbak, the end-blown flute ney, the large frame drum daf, the hammered dulcimer santur, and the four long-necked lutes tar, dotar, setar, and tanbur. The European string instrument violin is also used, with an alternative tuning preferred by Iranian musicians.
Carpet weaving is an essential part of the Persian culture, and Persian rugs are said to be one of the most detailed hand-made works of art.
Achaemenid rug and carpet artistry is well recognized. Xenophon describes the carpet production in the city of Sardis, stating that the locals take pride in their carpet production. A special mention of Persian carpets is also made by Athenaeus of Naucratis in his Deipnosophists, as he describes a "delightfully embroidered" Persian carpet having some "preposterous shapes of griffins".
The Pazyryk carpet—a Scythian pile-carpet dating back to the 4th century BC, which is regarded the world's oldest existing carpet—depicts elements of Assyrian and Achaemenid design, including stylistic references to the stone slab designs found in Persian royal buildings.

One of the most renowned traditions observed by the Persians is the festival of Nowruz. Considered the national New Year of the Iranian people, the festival of Nowruz has its roots in ancient Iranian traditions, and has been recognized within the UNESCO's Intangible Cultural Heritage Lists.

By mid-Safavid times the usage tājik for ‘Persian(s) of Iran’ may be considered a literary affectation, an expression of the traditional rivalry between Men of the Sword and Men of the Pen. Pietro della Valle, writing from Isfahan in 1617, cites only Pārsi and ʿAjami as autonyms for the indigenous Persians, and Tāt and raʿiat ‘peasant(ry), subject(s)’ as pejorative heteronyms used by the Qezelbāš (Qizilbāš) Torkmān elite. Perhaps by about 1400, reference to actual Tajiks was directed mostly at Persian-speakers in Afghanistan and Central Asia; ...

Excerpt 1: " All this evidence shows that the name arya Iranian was a collective definition, denoting peoples (Geiger, pp. 167 f.; Schmitt, 1978, p. 31) who were aware of belonging to the one ethnic stock, speaking a common language, and having a religious tradition that centered on the cult of Ahura Mazdā.". Excerpt 2: "The inscriptions of Darius I (see DARIUS iii) and Xerxes, in which the different provinces of the empire are listed, make it clear that, between the end of the 6th century and the middle of the 5th century B.C.E., the Persians were already aware of belonging to the ariya “Iranian” nation (see ARYA and ARYANS). Darius and Xerxes boast of belonging to a stock which they call “Iranian”: they proclaim themselves “Iranian” and “of Iranian stock,” ariya and ariya čiça respectively, in inscriptions in which the Iranian countries come first in a list that is arranged in a new hierarchical and ethno-geographical order, compared for instance with the list of countries in Darius’s inscription at Behistun" Excerpt 3: "Although, up until the end of the Parthian period, Iranian identity had an ethnic, linguistic, and religious value, it did not yet have a political import. The idea of an “Iranian” empire or kingdom is a purely Sasanian one". Excerpt 4:"It was in the Sasanian period, then, that the pre-Islamic Iranian identity reached the height of its fulfilment in every aspect: political, religious, cultural, and linguistic (with the growing diffusion of Middle Persian). Its main ingredients were the appeal to a heroic past that was identified or confused with little-known Achaemenid origins (Yarshater, 1971; Daryaee, 1995), and the religious tradition, for which the Avesta was the chief source.".
