Few peoples can look back on a continuous history as long, as proud, and as influential as the Persians. While many nations measure their past in centuries, the Persians measure theirs in millennia. They built one of the first great empires the world had ever seen more than two and a half thousand years ago, and through every conquest, every invasion, and every upheaval since, they have held onto a distinct identity, a magnificent language, and a sense of themselves as heirs to one of humanity’s oldest civilizations. To understand the people who today call their country Iran, and who call themselves Iranians while many of the world still calls them Persians, is to follow one of the great threads running through the whole story of human civilization.

Persians or Iranians

The two names cause endless confusion, so it is worth clearing up at the start. Iran is the name of the country, and it derives from a very old word meaning land of the Aryans, a term the people themselves have used for their homeland for thousands of years. Persia was the name long used by outsiders, taken from Pars or Fars, the southern region that was the original heartland of the Persian people and their first great empire. In 1935 the government formally asked the world to use Iran rather than Persia, which is why the country is now called Iran on every map.

Strictly speaking, the Persians are one people, the largest, among the several peoples who make up the nation of Iran. The country is also home to Azerbaijanis, Kurds, Arabs, Baloch, Turkmen, and others. But the Persians, with their language and culture, have been the dominant thread and the carriers of the great civilizational tradition, and so when the world speaks of Persian art, Persian poetry, or the Persian Empire, it is speaking of the heritage that sits at the heart of Iranian identity.

The First World Empire

The Persians stepped onto the stage of world history in the sixth century before the common era, when a remarkable king named Cyrus the Great united the Persian tribes and went on to conquer an empire of unprecedented size. The Achaemenid Empire that he founded stretched, at its height, from the Indus River in the east to Greece and Egypt in the west, making it the largest empire the world had yet known and one of the first to rule over many different peoples and cultures at once.

What set the Persian Empire apart was not only its size but its style of rule. Cyrus and his successors generally allowed the many peoples under their authority to keep their own religions, customs, and local governance, demanding loyalty and taxes rather than uniformity. A famous cylinder inscribed in the name of Cyrus, declaring his policies toward the peoples he ruled, has sometimes been called an early charter of tolerant kingship, and while modern readers should be careful not to read too much present-day idealism into an ancient royal document, the Achaemenid model of a multicultural empire held together by relatively light-handed rule was genuinely influential. It was these Persians whom the Greeks fought in the famous wars at Marathon, Thermopylae, and Salamis, conflicts that the Greeks remembered as a struggle for freedom and that gave the West a lasting and often distorted image of Persia as the great enemy.

The Roots of the Persian Language

The Persian language, called Farsi by its speakers, belongs to the Iranian branch of the great Indo-European language family. This places it in the same vast family as the languages of Europe and northern India, and makes it a distant cousin of English, Russian, Greek, and Hindi, and a closer relative of Kurdish, Pashto, Balochi, and the other Iranian tongues. The shared Indo-European ancestry is why a curious learner can spot familiar-looking words scattered through Persian, the word for mother, father, or brother carrying an echo of their English equivalents across thousands of years of separation.

Persian has one of the longest literary histories of any living language, and its story comes in three great stages. Old Persian was the tongue of the Achaemenid kings, inscribed in cuneiform on the cliffs and palaces of the empire. Middle Persian was the language of the later Sasanian Empire. And modern Persian, which emerged after the Islamic conquest, has remained remarkably stable for over a thousand years, so much so that Iranians today can read the great poetry of the medieval masters with far less difficulty than English speakers have with writing only a few centuries old.

After the Arab conquest, Persian absorbed a large vocabulary of Arabic words and adopted a modified Arabic script, yet it never became Arabic. It kept its Indo-European grammar and its own deep identity, and it went on to become a great prestige language across a huge region, the language of courts, poetry, and refinement from the Ottoman lands through Central Asia to Mughal India. To this day, Persian in its different forms is spoken not only in Iran but in Afghanistan, where it is called Dari, and in Tajikistan, where it is called Tajik, a reminder of how far the cultural reach of the Persian world once extended.

The Faith Before Islam

Long before the Persians became a Muslim people, they gave the world one of its most influential religions. Zoroastrianism, founded on the teachings of the prophet Zarathustra in the distant past, was the faith of the great Persian empires. It taught a vision of the universe as a cosmic struggle between a supreme good God and the forces of darkness and lies, in which human beings must choose, through good thoughts, good words, and good deeds, to side with the light. Many scholars believe that Zoroastrian ideas about heaven and hell, a final judgment, and the battle between good and evil influenced Judaism, Christianity, and Islam, making this Persian religion one of the quiet shapers of the wider religious imagination of humanity.

Under the Sasanian Empire, the last great Persian dynasty before Islam, Zoroastrianism was the state religion and Persian civilization reached new heights of art, architecture, and learning. The Sasanians were the rivals and equals of the Roman and Byzantine empires for centuries, and their court culture set a standard of splendor that later Islamic dynasties would consciously imitate. A small but proud community of Zoroastrians survives in Iran and in India, where their descendants are known as Parsis, keeping alive a faith that once lit the fire temples of a mighty empire.

The Arab Conquest and the Persian Response

In the seventh century the armies of the new Islamic faith, carried by the Arabs, swept out of Arabia and shattered the Sasanian Empire, and within a few decades Persia had been conquered and its ancient religion gradually displaced by Islam. For a people with such a strong sense of their own greatness, this was a profound shock. Yet the Persian response to conquest was not to vanish into the new Arab order but to transform it from within. Persians became the administrators, scholars, scientists, and poets of the Islamic world, and much of what is celebrated as the golden age of Islamic civilization was in fact the work of Persians writing and thinking within the framework of Islam.

Crucially, the Persians did not abandon their language as so many other conquered peoples did. While Egypt, Mesopotamia, and North Africa became Arabic-speaking, Persia kept Farsi alive, enriched it with Arabic vocabulary, and made it the vehicle of a literary culture of dazzling brilliance. This survival of the Persian language is one of the great acts of cultural endurance in world history, and it is the foundation on which the distinct identity of modern Iran still rests. Over the centuries the Persians also embraced, in large numbers, the Shia branch of Islam, which would eventually become the defining religious feature distinguishing them from their mostly Sunni neighbors, including the Turks to the west.

The Glory of Persian Poetry

If there is one art in which the Persian genius shines brightest, it is poetry. No nation on earth holds its poets in deeper reverence than Iran. The medieval masters of Persian verse are not dusty figures studied only in schools but living presences whose words are quoted in everyday conversation, recited at weddings and funerals, and consulted almost like oracles. Ferdowsi, who composed the vast epic of Persian kings and heroes, is credited with helping to save the Persian language itself by writing it in a magnificent work that drew on the nation’s ancient legends. Hafez, the supreme lyric poet of Shiraz, is so beloved that many Iranian homes keep his collected poems alongside the Quran and open them at random for guidance.

Rumi, the great mystic poet, has become one of the best-selling poets in the modern Western world, his verses on love and the divine speaking across the centuries and across cultures. Omar Khayyam, known in the West for his meditations on wine, mortality, and the fleeting nature of life, was also a brilliant mathematician and astronomer. Saadi, whose moral tales and reflections on human conduct include lines about the common humanity of all people, has been quoted at the United Nations. This is a civilization that poured its deepest thoughts about love, God, justice, and the meaning of existence into poetry, and that poetry remains the beating heart of Persian identity.

The Safavids and the Shia Identity

After centuries of rule by various dynasties, including the devastating invasions of the Mongols and later the conqueror Tamerlane, a new and decisive chapter opened in the sixteenth century with the rise of the Safavid dynasty. The Safavids reunited Persia as a powerful independent state and made a fateful decision that would shape Iranian identity to the present day: they established Shia Islam as the official religion and converted the population to it, often by force. This set Persia apart, as a Shia island in a largely Sunni Muslim sea, and reinforced the sense of Iran as a distinct civilization with its own faith, its own language, and its own destiny.

Under the Safavids, Persian art and architecture reached a new golden age. The city of Isfahan, rebuilt as a glorious capital, became one of the most beautiful cities in the world, its great square, gardens, bridges, and tile-covered mosques the envy of visitors from across Eurasia. The famous saying that Isfahan is half the world captured the wonder it inspired. The exquisite Persian carpets, miniature paintings, and architecture of this era remain among the supreme achievements of human craftsmanship.

The Struggle of the Modern Age

The path into the modern world was difficult and often humiliating for Iran. By the nineteenth century the country had fallen far behind the industrializing powers, and it became a pawn in the rivalry between the British and Russian empires, which carved out spheres of influence and extracted lucrative concessions, including over the oil that would soon be discovered in vast quantities. A constitutional revolution in the early twentieth century tried to limit royal power and modernize the state, an early and important experiment in democracy in the region, though its gains proved fragile.

One episode in particular left a lasting scar on the national memory. In the early 1950s a popular elected prime minister moved to nationalize the country’s oil industry, which had been controlled by a British company that took the lion’s share of the profits. In 1953 he was overthrown in a coup orchestrated with the involvement of British and American intelligence, which restored the power of the shah. This intervention, in which foreign powers toppled a popular government to protect their oil interests, is remembered bitterly in Iran to this day and helped poison relations between Iran and the West for generations. An honest account cannot leave it out, for it is impossible to understand modern Iranian distrust of the West without it.

The Shah and the Revolution

After the 1953 coup, the shah ruled with growing authoritarianism, backed by Western support and funded by oil. He pushed an ambitious program of modernization and Westernization, building industry, expanding education, and granting women new rights, but he did so as an autocrat who tolerated no dissent and relied on a feared secret police to crush opposition. The benefits of the oil boom flowed unevenly, the gap between a glittering elite and the urban poor widened, and many Iranians felt that their culture and their faith were being trampled in a headlong rush to imitate the West.

In 1979 this resentment exploded into one of the great revolutions of the twentieth century. An extraordinary coalition of secular liberals, leftists, and devout Muslims united to overthrow the shah, who fled into exile. But it was the religious wing, led by the exiled cleric Ayatollah Khomeini, that seized control of the revolution and reshaped it in its own image. Iran was declared an Islamic Republic, a unique system in which an unelected supreme religious leader holds ultimate authority above the elected president and parliament. The hopes of the many revolutionaries who had wanted freedom and democracy were soon crushed, as the new regime turned on its former allies and imposed its own strict vision of an Islamic society.

Life Under the Islamic Republic

An honest portrait of contemporary Iran must reckon with the harsh realities of the system that has governed it since 1979. The Islamic Republic has imposed strict religious rules on a population, including compulsory dress codes for women, and has repressed dissent, jailed and executed political prisoners, censored the press, and crushed waves of protest, often with deadly force. A long and terrible war with neighboring Iraq in the 1980s, which Iraq began with an invasion, cost hundreds of thousands of Iranian lives and deepened the regime’s grip. International isolation and sanctions, tied to the country’s nuclear program and its support for armed groups abroad, have inflicted serious hardship on ordinary Iranians.

Yet the picture is far more complex than the image of a uniformly oppressive theocracy that often appears in the outside world. Iran is a deeply divided society in which a large, young, educated, and often strikingly secular-minded population chafes against the restrictions imposed on it. Iranians have repeatedly risen up to demand greater freedom, most visibly in mass protest movements that have shaken the regime, including the powerful uprising sparked by the death of a young woman in the custody of the morality police. Behind closed doors, in private homes, and increasingly in open defiance, many Iranians live lives strikingly at odds with the official ideology. The gap between the state and much of the society it rules is one of the central facts of the country today.

The Persian Soul

Beyond politics, the texture of Persian life is shaped by traditions far older than any regime. The greatest celebration of the Iranian year is not an Islamic holiday at all but Nowruz, the Persian New Year, which falls on the spring equinox and has been celebrated for thousands of years, going back to Zoroastrian times. Families gather, homes are cleaned, special foods are prepared, and a symbolic table is laid out, in a festival of renewal that binds Iranians, and many neighboring peoples who share the tradition, to their most ancient heritage. That this pre-Islamic festival remains the heart of the Iranian calendar speaks volumes about the depth and resilience of Persian identity.

Persian culture treasures refinement, courtesy, and a subtle, elaborate code of politeness known as taarof, an intricate dance of offers and refusals that can baffle outsiders. It treasures the garden, that walled paradise of trees, flowers, and running water that was a Persian invention and gave the very word paradise to the languages of the world. It treasures food, from fragrant rice dishes and stews to the saffron and pomegranate and herbs that fill the Persian kitchen. And above all it treasures the word, the poem, the perfectly turned phrase, valued in Iran as nowhere else on earth.

A Tradition of Science and Thought

Alongside their love of poetry, the Persians have a deep tradition of science, philosophy, and learning that flourished especially in the centuries after the coming of Islam. Persian scholars stood at the forefront of the medieval intellectual world. The polymath Ibn Sina, known in the West as Avicenna, wrote a medical encyclopedia that was used as a standard textbook in European universities for centuries, and made lasting contributions to philosophy. The mathematician al-Khwarizmi, from the Persian cultural world, gave his name to the very word algorithm and helped lay the foundations of algebra. Astronomers built sophisticated observatories, and thinkers debated the deepest questions of theology and philosophy with a rigor that influenced both the Islamic and the Christian worlds.

This intellectual heritage has not faded. Modern Iran, for all its political troubles, produces large numbers of engineers, scientists, and doctors, and Iranian students consistently excel in international competitions in mathematics and the sciences. The country has developed advanced capabilities in fields from medicine to engineering despite years of sanctions and isolation. The Iranian mathematician Maryam Mirzakhani became the first woman ever to win the Fields Medal, the highest honor in mathematics, a source of immense national pride that captured both the brilliance of Iranian talent and the painful loss of so much of it to emigration. The hunger for knowledge that built the medieval golden age still burns brightly in Iran today.

The Persians of the Wider World

The upheavals of the modern era, above all the 1979 revolution and the repression that followed, scattered a large Iranian diaspora across the globe. Hundreds of thousands of Iranians, many of them highly educated professionals, settled in the United States, Canada, Europe, and elsewhere, building prosperous communities far from home. In cities like Los Angeles, which is sometimes nicknamed Tehrangeles for its large Iranian population, the diaspora has kept Persian culture, music, food, and language alive while contributing remarkably to their adopted countries in medicine, technology, academia, and the arts.

This diaspora carries a complicated relationship with the homeland, a deep love for Persian culture and a painful estrangement from the regime that rules it. Many long to see a different Iran and to return to a country they remember or imagine. Their success abroad has also helped reshape the world’s image of Iranians, countering the political headlines with the visible reality of a cultured, accomplished, and warm people. They are living proof that Persian civilization is far larger than the borders of any single state or the policies of any single government.

An Ancient People Facing the Future

The Persians stand as one of the oldest continuous civilizations on earth, a people who built the first true world empire, who gave humanity profound religious ideas and some of its most beautiful poetry, who survived conquest after conquest while keeping their language and their soul intact. They are heirs to Cyrus and to Hafez, to the fire temples of Zoroaster and the tiled domes of Isfahan, to a tradition of refinement, hospitality, and learning that stretches back thousands of years.

And they are also a people living through a difficult present, caught between a proud heritage and an authoritarian state, between a young population hungry for freedom and a system reluctant to grant it, between isolation and the longing to rejoin the world. To understand the Persians is to hold their glorious past and their troubled present together, and to recognize that beneath the politics that dominate the headlines lies one of the deepest, richest, and most resilient cultures humanity has ever produced. Whatever the coming years bring, the Persians will continue to do what they have always done: endure, adapt, and keep alive a civilization too old and too great to be erased.
