When was Persia renamed “Iran”…and Why? | Far Horizons
March 4, 2024 - The formal adoption of “Iran” in 1935 by Reza Shah Pahlavi marked a significant turning point, symbolizing a deliberate reconnection with the nation’s ancient past and a step toward modern nation-statehood. This change, far from a mere alteration of nomenclature, was a manifestation of Iran’s efforts to redefine its identity, distancing itself from colonial legacies and orientalist perspectives. Reza Shah’s decree, issued on the Persian New Year, was a declaration of cultural sovereignty, aiming to revive the glory of Iran’s imperial past while navigating the path towards modernization.

When Did Persia Become Iran and Why? | History Hit
The rest of the world paid Persia new attention, and the British were the first to capitalise on the discovery, setting up the Anglo-Persian Oil Company in 1909, which took total control of Iran’s oil industry. Iran’s oil and petroleum industry have remained at the heart of internal and external politics ever since: the influence of Western powers in Iran helped lead a backlash in the formal of cultural ‘cleansing’ and conservatism, and the formal establishment of Iran as an Islamic Republic. For many modern day Iranians, including the diaspora, the issue comes with wider connotations.

r/AskHistorians on Reddit: Difference between Iran and Persia?
June 6, 2023 -

So i'm Iranian myself, and from what I understood, Iranians never really called their country Persia. The name for Persia came from the Province of Parsa which is now called Pars / Fars in New Persian. Greeks used the word Persia to describe Iran as a whole and it stuck for most countries until Reza Shah (king of Iran) requested people call it Iran not Persia.

But on a Achaemenid description at Persepolis, Darius says this:

King Darius: This country Persia which Ahuramazda gave to me is a good country, full of good horses, full of good men. By the favor of Ahuramazda and of me, king Darius, this country fears no other country.

Is he referring to the Province only? Why is he calling it a country? or is he saying this to refer to his empire as a whole?

I think my answer linked by u/Pyr1t3_Radio more or less overs the distinction between "Iran" and "Persia," but I do want to address the inscription you referenced. Partly because DPd is a pretty obscure example to run across that I think is actually from a very interesting set of royal inscriptions, and partly because your confusion on the use of "country" runs up against pet peeve of mine. As I explained more in that other thread, Parsa / Persia only refers to the specific province. If you go a bit further down into the sub comments there, you'll also find one where I mention that the Achaemenids apparently did not have a singular name for their whole territory, instead preferring to list all of the major lands and peoples under their control. This was often framed as "these are the countries which I seized outside of Persia..." followed by a list of specific locations. You can also find examples of the Achaemenids drawing a distinction between Persian and Aryan (meaning Iranian in an ethno-linguistic sense), in the phrase "I am [king's name and titles], an Achaemenid, a Persian, son of a Persian, an Aryan, having Aryan lineage." Persian is used to specify relation to the province while Aryan indicates a broader identity. You can see both of these phrases used in inscription DNa . As for the question about calling it a country, hopefully the use of "countries" in that stock phrase above provides some additional context. It is an unintentionally confusing translation choice in modern English. The Old Persian word is dahyu (plural dahyunam), which can also be translated as just "land" or "place." In this context, "country" is using a more general meaning of "an area or region" rather than what you seem to be thinking of: "a specific sovereign state." Both are perfectly valid definitions, but "an area or region" is actually the older meaning of the word, which originated in the medieval Latin phrase contra terra, meaning "the land across." In modern English, we tend to use "country," "state," "nation," and "nation-state," more or less interchangeably. However, especially when looking at older documents or older translations of documents, these words all have different original meanings. While a country can refer to any given region, "nation" was originally used more like "ethnicity" (the same is true for the word "race"). A good example of this in an Achaemenid context is The Gate of All Nations at Persepolis, which is called the duvarthim visadahyum in Old Persian, duvarthim meaning "gate," visa meaning "all," and dahyum being a possessive form of dahyunam, more accurately meaning "lands." Compare that to the common use of "nations" in Biblical translations such as "And He will judge between the nations" in Isaiah 2:4, where the original Hebrew word is goyim, which refers to non-Jewish peoples rather than places or polities. This original use of "nation" is the reason for the term "nation-state," which seems oxymoronic in modern usage but originally specified a "state" (the earliest of these words to originally refer to a sovereign polity English) dedicated to one specific "nation" (as in ethnicity). All of that said, looking at DPd is especially interesting to me because it's part of a fairly unique set of inscriptions in Achaemenid history. Along with DPe, f, and g, this inscription is carved into the southern wall of the Persepolis terrace containing the main royal palace. It's a very odd placement because in that position they would have been all but invisible. They are high above, and behind, the small cluster of additional palaces and public buildings called Persepolis South. When Darius the Great initially comissioned these inscriptions, they would have been visible to workers ascending a sort of back stair case onto terrace for construction, but not to the literate nobles and their attendance ascending the main entrance on the western side. Despite this, these inscriptions are also some of the only examples that explicitly address someone, presumably future kings, with DPe saying King Darius [says]: If you think, "I fear no one else," then protect the Persians. Because when the Persians are protected, their happiness will remain unbroken, and the favor of Ahuramazda will come down upon the royal house." The explicit focus on Persia and the Persian people in these inscriptions is almost unique. Similar phrases are used in other inscriptions to call on Ahura Mazda to protect the whole empire or the royal family, but rarely Persia specifically. Equally strange is DPd's focus on protecting Persia "...from invaders, from famine, and from the Lie!" Achaemenid inscriptions (and ancient royal inscriptions in general) typically avoid even suggesting that hardship could befall the ruling province directly unless something had happened recently. Invaders is especially odd, as Parsa was nestled deep in the heart of imperial territory. On top of that, Achaemenid inscriptions are often trilingual, with the same message repeated in Old Persian, Babylonian Akkadian, and Elamite. However, while DPf and g are similar texts in Elamite and Akkadian, they are not the same message. They're not even the same text as one another. DPf focuses on the construction of Persepolis in Elamite, and DPg describes the extent of the Empire in Akkadian. Unlike most inscriptions of that sort, DPg only highlights Persia and Media by name, reducing the rest of the empire to "other dahyunam" and geographic descriptions. It's a set of four inscriptions, directed at three separate audiences, each with their own distinct message, which is utterly unique in the Achaemenid corpus on its own and only more so with the odd focus on discussing threats to Parsa itself to the Old Persian-literate audience.
