Iran
iran
Middle Persian
“The country Westerners called Persia never used that name at home.”
The Avestan texts, the sacred scriptures of Zoroastrianism composed perhaps as early as 1500 BCE, use Airyana Vaēja for the primordial Iranian homeland. The word Aryana passed into Old Persian as a general term for the Iranian peoples, and from there into Parthian and Middle Persian as Ērān. In the third century CE, the Sasanian king Ardashir I used Ērānšahr in official inscriptions at Naqsh-e Rostam as the formal name for his realm.
The Greeks called it something else entirely. They knew the southwestern region as Persis, from Old Persian Pārsa, the name of Cyrus the Great's home province in what is now Fars. This regional label spread through Greek historiography into Latin, then into Arabic, and eventually into every major European language. By the medieval period, Persia was the standard term abroad while Iranians continued to use forms of Iran in Persian-language texts.
The duality persisted for centuries without obvious friction. Persian poets, Hafez in the 14th century and Saadi in the 13th, wrote in Persian about a land they called Iran. Marco Polo called it Persia. The Safavid dynasty (1501-1736) ruled Iran and sent ambassadors to European courts where their kingdom appeared on maps as Persia.
In 1935, Reza Shah Pahlavi formally requested that foreign governments use Iran rather than Persia in diplomatic communications. The motivation was nationalist: he wanted the name Iranians actually used for themselves to be the name the world used too. Historians of Iranian culture pushed back, since Persia carried associations with poetry, art, and carpets that Iran did not yet hold internationally. The word Iran is now standard in official contexts; Persian survives as the name of the language, the carpet style, and the literary tradition.

The switch from Persia to Iran in 1935 was partly diplomatic, partly political, and partly a reclamation. Persia was a Greek regional label that had spread across the world while Iran continued quietly in Persian-language use at home. Reza Shah Pahlavi wanted the name Iranians actually used to be the one the world used too. The request seemed simple but changed a word that had been fixed in European minds since ancient Greece.
Persia did not disappear. It lives on as the name of the language, the carpet style, the cat breed, and the literary tradition. The country standardized on Iran while the culture kept Persia for the things that carried its weight. History named it twice, and both names stuck.
