When we say "ancient Persia," most people picture vast desert palaces, armies of ten thousand warriors, and a civilization that once stretched from Egypt to the borders of India. But here's a surprising starting point: the people who built that civilization never called it Persia. That name belonged to outsiders — specifically, the Greeks. Understanding what ancient Persia was actually called, in its own language and in the languages of its neighbors, reveals something profound about how empires are named, remembered, and sometimes misremembered across history.
The Name the Persians Used for Themselves: Iran
The people of ancient Persia referred to their land as Aryana or, in its evolved form, Iran. This name derives from the Old Iranian word Arya, meaning "noble" or "free," the same root that gives us the linguistic term "Aryan" used in Indo-European studies. The connection between the ancient name and the modern country is direct and unbroken — Iran is not a new name adopted in the 20th century as a political invention, but rather the oldest name the people of that land gave themselves.
In Old Persian inscriptions, Darius the Great described himself as "king of the Aryans" (xšāyaθiya Āryānām). The word Iran itself is simply the modern Persian descendant of Āryānām, meaning "of the Aryans" or "land of the Aryans." This gives Iran one of the oldest continuously used national names anywhere in the world.

Where "Persia" Actually Came From
If the people themselves said Iran, where did the Western name "Persia" come from? The answer lies in a single province.
The ruling dynasty that built the first great Persian empire — the Achaemenid Empire and its conquests — originated in a southwestern region of the Iranian plateau known in Old Persian as Pārsa. This is the province we now call Fars, in modern-day Iran. When the Achaemenid kings such as Cyrus the Great and Darius I rose to dominate the ancient world, the Greeks encountered them through this regional identity.
Greek writers rendered Pārsa as Persis (Περσίς) or Persai, referring both to the province and to its people. From Greek, the name passed into Latin as Persia, and from Latin into virtually every major European language. So "Persia" in Western usage is, strictly speaking, the name of a region within Iran that got applied — through the outsider perspective of Greek observers — to the entire civilization.
What Other Ancient Civilizations Called It
The Babylonian and Elamite View
Ancient Mesopotamian civilizations had their own ways of recording Persia. Babylonian cuneiform texts used the name Parsumaš or Parsumash for the early Persian settlers, a name closely related to Pārsa. Elamite texts from the same region, which predate the Achaemenid rise to power and were actually used by the Achaemenid court in its administrative records, similarly rendered Persian names in their own phonetic conventions.

The famous Behistun Inscription — carved by Darius the Great around 522–486 BCE — was written in three languages simultaneously: Old Persian, Elamite, and Babylonian. Each version used its own script and phonetic system, but all referred to the same empire and king. This trilingual monument is one of our most important windows into how the empire understood its own identity across multiple linguistic traditions.
The Egyptian Perspective
When Cambyses II conquered Egypt in 525 BCE, Egyptian scribes and priests had to find a way to record his name and title. Egyptian hieroglyphic texts referred to the Persian rulers using Egyptianized versions of their names, and the land they came from was noted in terms familiar to Egyptian geographic understanding. The Persians were recognized as a new ruling power but recorded in the framework of Egyptian scribal convention, which often mapped foreign names onto familiar phonetic patterns.
Hebrew and Biblical Names
In Hebrew scripture, the empire appears primarily as Paras (פָּרַס), another direct phonetic borrowing of Pārsa. The Hebrew Bible — particularly the books of Ezra, Nehemiah, Esther, and Daniel — contains substantial references to Persian kings and the Persian court. Cyrus the Great is specifically named in Isaiah and Ezra as the king who permitted Jewish exiles to return to their homeland from Babylonian captivity, making the Persian name deeply embedded in Jewish and later Christian historical consciousness.
Sanskrit and Indian Records
On the eastern end of the Achaemenid Empire, Sanskrit texts and Indian traditions referenced Persia as Parsa or Parśava. The Persians under Darius extended their empire into the northwestern Indian subcontinent, and this contact left traces in both administrative records and cultural memory. The shared Indo-Iranian linguistic roots between Old Persian and Sanskrit meant that the two civilizations were, in a meaningful sense, linguistic cousins — which is part of why the name forms look so similar across so many ancient languages.
The Achaemenid Empire's Own Royal Terminology
Inside the empire itself, official royal titles tell their own story. Achaemenid kings used the grand title Xšāyaθiya Xšāyaθiyānām — "King of Kings" — a phrase that announced dominion not just over a single people but over a hierarchy of subject rulers. This title was not mere boast; it reflected the empire's genuine administrative structure, in which local kings and governors (satraps) operated under Persian imperial authority.
The empire itself was sometimes referred to in royal inscriptions as the land of the Pārsa and the Māda — Persia and Media — acknowledging the two dominant Iranian peoples whose combined power formed the empire's core. The Medes had preceded the Achaemenids as the dominant Iranian power, and their incorporation into the Persian state was significant enough to be reflected in official titulature.
After the Achaemenids: Did the Name Change?
The Achaemenid dynasty fell to Alexander the Great in 330 BCE, and the subsequent Hellenistic period introduced Greek administrative culture into the former Persian territories. Greek rulers used Greek names and Greek geographic terms, but the underlying Iranian population continued to use their own names for their land.
When Iranian rule was restored under the Parthians and later the Sassanians, the name Ērān (a Middle Persian form of Iran) returned to official prominence. The Sassanian Empire, which ruled from the 3rd to the 7th century CE, explicitly styled itself the "Empire of Iranians" (Ērānshahr), making the identity of the state inseparable from the Iranian name. You can explore how this imperial identity evolved through the Parthian and Sassanian dynasties, which each adapted and reshaped the Persian legacy in distinctive ways.
The 1935 Name Change: A Modern Misunderstanding Corrected
A persistent myth holds that Iran only became "Iran" in 1935, when Reza Shah Pahlavi formally requested that foreign governments use "Iran" rather than "Persia" in diplomatic correspondence. This date is real, but the interpretation is often wrong. Reza Shah did not invent the name Iran — he simply asked the outside world to stop using the Greek-derived outsider term and to adopt the name the Iranian people had always used for themselves.
Within Iran, the country had been called Iran (in its various historical forms) continuously for millennia. The 1935 shift was an act of reclaiming indigenous nomenclature on the international stage, not a renaming.
In Western usage, both terms have long histories. "Persia" carries cultural and historical resonance, particularly when referring to the ancient empires and classical arts. Many scholars still use "Persia" or "Persian" when discussing the pre-Islamic and early Islamic cultural heritage, while "Iran" and "Iranian" are preferred for the modern state and in many contemporary academic contexts. Neither usage is wrong — they reflect different linguistic traditions applied to the same continuous civilization.
Why the Multiplicity of Names Matters
The fact that one civilization accumulated so many names is not a trivial linguistic footnote. It reflects the sheer geographic and cultural reach of Persian civilization at its height. When your empire spans from the Aegean coast to the Indus Valley, you will be seen, recorded, and named by dozens of different peoples — each filtering you through their own language, their own script, and their own frame of reference.
The Greek name stuck in Western tradition because Greek historical writing, particularly Herodotus's Histories, became the foundational text through which Western civilization understood the ancient world. Herodotus wrote extensively about the Persian Wars from a Greek perspective, and his Greek terminology colonized Western vocabulary for centuries. The very word "history" in English derives from Greek — so it is perhaps unsurprising that the Greek name for Persia also took root.
Meanwhile, in the Islamic world and in Iran itself, the name Iran and the Persian cultural identity persisted through Arabic-script literature, poetry, and administrative tradition. The great Persian-language literary tradition — the poetry of Hafez, Rumi, and the epic narratives compiled by Ferdowsi — preserved and celebrated Iranian identity under that name across the medieval period, regardless of what Greek-derived terms outsiders were using.
A Name That Carries Civilization
Names are never neutral. What a civilization calls itself, and what others call it, encodes relationships of power, perspective, and historical memory. "Persia" tells you something about Greek encounter and Western inheritance. "Iran" tells you something about the people's own continuity and self-understanding. Pārsa, Parsumaš, Paras, Ērānshahr — each variant is a different culture's record of the same astonishing human achievement.
When you ask what ancient Persia was called, the full answer is that it was called many things by many people — and that variety of names is itself a testament to how far its influence reached. The civilization was large enough, powerful enough, and culturally significant enough that civilizations from the Mediterranean to South Asia had to find words for it. Each found their own.
