Who are the Iranians?
From Cyrus’s empire of tolerance to the poets who outlived every conqueror — the Persian story is civilization’s longest comeback.
Last updated: October 2026
Few peoples have been conquered so often and survived so completely. The Persians built the first world empire, lost it to Alexander, to Arabs, to Mongols — and each time, the conquerors ended up speaking Persian, writing Persian poetry, and governing in the Persian style. Iran is the graveyard of empires that tried to erase it.
Iranians are the people of Iran, a country of roughly ninety million people at the crossroads of the Middle East, Central Asia and South Asia — and the name carries a second, older meaning. The Iranian peoples are a family of peoples who speak Iranian languages and share roots stretching back more than three thousand years: Persians, Kurds, Pashtuns, Tajiks, Baloch, Ossetians and others, spread today from Turkey to western China. Within Iran itself, the population is diverse: a Persian-speaking majority alongside large Azeri, Kurdish, Lur, Baloch, Arab, Turkmen and other communities. "Persian" properly describes one ethnicity and one language; "Iranian" describes a nationality and a far older civilisation. The distinction matters, because Iran has always been a mosaic, not a monolith.
That diversity is written into the country's geography. Iran is a high plateau ringed by mountains — the Zagros in the west, the Alborz in the north — with deserts at its heart and fertile fringes along the Caspian Sea and the Persian Gulf. For millennia, peoples have moved through it: traders on the Silk Road, armies from east and west, nomads and settlers. Iran's history is the story of how a place at the centre of the world's traffic kept remaking itself while staying recognisably itself.
Iranian civilisation begins long before Iran. The Elamites built cities in the south-west from the third millennium BCE. In the first millennium BCE, the Medes forged a kingdom in the north-west, and from their shadow rose Cyrus the Great, who founded the Achaemenid Empire around 550 BCE. Within a generation, Cyrus and his successors ruled the largest empire the world had yet seen, stretching from India to Greece and Egypt. The Achaemenids governed through satrapies, built the Royal Road, standardised coinage, and proclaimed a policy of tolerance toward the religions and customs of conquered peoples — most famously in the Cyrus Cylinder, sometimes called the first charter of human rights, though historians debate that label.
Darius I raised Persepolis, the ceremonial capital whose carved staircases still show delegations of the empire's peoples bringing tribute. Alexander the Great conquered the empire in 330 BCE and burned Persepolis, but Greek rule did not erase Iranian culture. The Parthians, and then the Sasanians from 224 CE, rebuilt an Iranian imperial tradition that rivalled Rome for four centuries. Sasanian art, court culture and Zoroastrian religion — the faith of the prophet Zoroaster, with its dualism of truth and falsehood — shaped the region long after the empire fell, and Zoroastrian communities survive in Iran and India to this day.
The Arab conquest of the seventh century brought Islam to Iran and ended the Sasanian Empire. Yet the conquest produced one of history's great cultural paradoxes: the conquered transformed the conquerors' civilisation. Persian administrators, scholars and writers became central to the Islamic world, and the Persian language — written now in the Arabic script, enriched with Arabic vocabulary — survived and flourished. By the tenth century, the poet Ferdowsi was composing the Shahnameh, the Book of Kings, an epic of some fifty thousand couplets that preserved the pre-Islamic legends of Iran and fixed the Persian language for all time.
The centuries that followed were a golden age of Persian letters and science. Rumi wrote his ecstatic Masnavi in Konya; Hafez and Saadi shaped a lyric tradition that is still memorised and quoted across the Persian-speaking world; Omar Khayyam wrote quatrains and reformed the calendar; Avicenna, who wrote in both Arabic and Persian, systematised medicine and philosophy for centuries. Persian became the language of courts and poetry from Anatolia to India, and Persianate culture — a blend of Iranian, Islamic and Central Asian elements — was one of the great civilisations of the medieval and early modern world.
In 1501, the Safavid dynasty made Twelver Shia Islam the state religion, a decision that set Iran's religious identity apart from its Sunni neighbours and still defines it. The Safavid capital at Isfahan, with its great square and tiled mosques, remains a monument of that age. The Qajar dynasty that followed in the nineteenth century presided over a weaker state, squeezed between the expanding Russian and British empires and forced into unequal concessions. Reformers pushed back: the Constitutional Revolution of 1905–1911 created one of the Middle East's first parliaments, and the discovery of oil in 1908 made Iran a prize in great-power politics.
The twentieth century brought the Pahlavi dynasty, founded by Reza Shah in 1925, which drove rapid modernisation — railways, universities, unveiled women, centralised rule — and deep resentment at authoritarian methods and foreign influence. The Anglo-Soviet occupation of 1941, the oil nationalisation crisis of 1951–53 under Prime Minister Mossadegh, ended by a coup backed by the United States and Britain, and the White Revolution of the 1960s all fed a gathering opposition. In 1979, the Islamic Revolution overthrew the Shah and established the Islamic Republic under Ayatollah Khomeini, combining clerical authority with elected institutions in a system that has endured, contested and evolving, ever since.
Iranian identity today is layered: national, religious, ethnic, linguistic and generational, and Iranians argue about it as fiercely as any people. Nowruz, the Persian New Year at the spring equinox, is celebrated by hundreds of millions of people across the Iranian world, from the Balkans to Central Asia. Iranian cinema — the films of Abbas Kiarostami, Asghar Farhadi and others — is among the most honoured in the world. Iranian poetry remains a living art: lines of Hafez are still consulted for guidance, and his tomb in Shiraz draws pilgrims of every faith and none.
Millions of Iranians live abroad, in a diaspora that grew after 1979 and again after later waves of emigration, with large communities in the United States, Canada, Europe and the Gulf. Inside Iran, a young, educated and highly connected population continues to shape the country's culture, science and politics. To ask who the Iranians are is therefore to ask about a people whose story spans empires and revolutions, whose language has carried one of the world's great poetic traditions, and whose identity has never been a single thing — it has always been a conversation across three thousand years.
