The Great Name Shift: Why Persia Became Iran

Mr. Casey Boyer 18 Jun 2025

**The ancient land known to the Western world for centuries as Persia underwent a profound transformation in the 20th century, culminating in its official designation as Iran. This pivotal shift, which formally took effect in March 1935, was far more than a mere linguistic update; it was a deliberate act rooted in a desire to strengthen national identity, reclaim historical narratives, and redefine the nation's place on the global stage.** It’s a story steeped in political ambition, cultural pride, and a deep connection to a past often misunderstood by outsiders. For many, the name "Persia" evokes images of grand empires, intricate carpets, and poetic traditions. Yet, for the people of the land, "Iran" had always been the indigenous name, used for millennia to refer to their homeland. The decision to formalize this change for international recognition, spearheaded by Reza Shah Pahlavi, marked a significant moment in the country's modern history, symbolizing a fresh start and a new era of self-assertion.

A Legacy of Names: Unpacking "Persia" and "Iran"

To truly grasp the significance of why Persia became Iran, we must first delve into the historical nomenclature of this fascinating nation. For centuries, the world knew this land by two distinct names, one propagated externally and the other cherished internally. This duality is central to understanding the motivations behind the 1935 decision.

The Western Lens: How "Persia" Came to Be

The term "Persia" is deeply ingrained in Western historical narratives and popular culture. Its origins trace back to "Parsa," the name of a specific region in southwestern Iran. This area was the ancestral homeland of the Achaemenid Empire's founders, the dynasty that established one of the largest empires of the ancient world. However, it was primarily Greek historians, such as Herodotus, who propagated this designation. They referred to the Achaemenid Empire, and subsequently the entire kingdom, as "Persia," derived from their pronunciation of "Fars," the central region within the Persian Empire where its capital, Persepolis, was located. This Greek designation was then adopted by Western cultures, becoming the prevalent exonym—the name used by outsiders to refer to a place. Over time, "Persia" became synonymous with the vast cultural and historical legacy of the region in the global consciousness, yet it remained an external label.

The Indigenous Truth: The Enduring Name "Iran"

While the Western world knew it as Persia, the people themselves had consistently referred to their country as "Iran" for millennia. This indigenous name, with its deep historical roots, signifies "Land of the Aryans." The term "Aryan" in this context refers to the Indo-Iranian peoples who settled the Iranian plateau in ancient times, forming the cultural and linguistic bedrock of the nation. Historical evidence suggests that at least as early as the Sassanid Empire (224–651 CE), the inhabitants referred to their realm as "Iran" or "Iranshahr." Exact spellings and pronunciations may have varied over the millennia, but the core name consistently remained "Iran" or a close variant. This internal consistency highlights a powerful, unbroken thread of national identity that predates Western interaction by centuries. The country referred to itself as Iran from the onset, making the 1935 change not an adoption of a new name, but a formal insistence that outsiders use the name its people had always known.

The Dawn of a New Era: When Persia Became Iran

The formal request for the international community to adopt "Iran" as the official name of the country came into force in March 1935. Specifically, it was on the Persian New Year, 21 March 1935, that Reza Shah Pahlavi, then the monarch of Persia, made the momentous announcement. This date was strategically chosen, symbolizing a fresh start and a renewed national identity aligned with ancient traditions. The Iranian government requested that all countries with which it had diplomatic relations begin using "Iran," which is simply the word for Persia in the Persian language. This decision marked a pivotal cultural and political change, signifying a deliberate move away from a name perceived as externally imposed and towards one deeply rooted in the nation's own history and self-perception. It was a clear declaration of sovereignty in naming, asserting the nation's right to be known by its true, indigenous name.

Reza Shah's Vision: Why the Name Change Was Imperative

Reza Shah Pahlavi's decision to formalize the name change from Persia to Iran was a cornerstone of his broader program of modernization and national consolidation. His motivations were multifaceted, driven by a powerful vision for a strong, unified, and self-respecting Iran. One primary aim was to strengthen national identity by embracing the term "Iran," which locals had used for centuries. Reza Shah believed that "Persia" felt "too colonial, oriental, and demode." This sentiment reflected a desire to shed the exoticized and often condescending image perpetuated by Western narratives, which frequently depicted the East as static and backward. The name change was also a strategic move to reconnect the nation with its ancient Aryan roots, a concept central to the nationalist ideologies of the early 20th century. By emphasizing "Iran"—the "Land of the Aryans"—Reza Shah sought to forge a modern national identity that drew strength from a glorious past, distinct from the more localized "Parsa" from which "Persia" originated. The core issue lay with its exonyms; while Iranians had always referred to their country as Iran, the international community continued to use Persia. This discrepancy was seen as an impediment to a unified national image. The decision symbolized a fresh start and a new era, asserting Iran's autonomy and its place as a modern, sovereign nation with a proud, ancient heritage.

The Aryan Connection: A Deeper Dive into "Iran"

The etymology of "Iran" is derived from "Eran" or "Airyanem Vaejah," meaning "Land of the Aryans." This ancient designation links the nation directly to the Indo-Iranian peoples who migrated to the plateau thousands of years ago, establishing the linguistic and cultural foundations that persist to this day. For Reza Shah, emphasizing this Aryan connection was more than a historical nod; it was a potent tool for nation-building. In the early 20th century, many nationalist movements across the globe sought to define their identity through perceived racial or ethnic purity and ancient origins. For Iran, the Aryan narrative provided a powerful, unifying myth that transcended regional loyalties and connected the modern state to a glorious, pre-Islamic past. This emphasis on Aryan heritage was intended to foster a sense of shared identity and pride among the diverse ethnic groups within Iran, presenting them all as descendants of a common, noble lineage. It was a deliberate effort to create a cohesive national narrative that could underpin a modern, centralized state. The political and racial implications of this connection were significant, aligning with the broader global currents of nationalism and self-determination that characterized the interwar period. By reclaiming "Iran," the nation was not just changing a name; it was reaffirming its unique historical trajectory and its profound connection to an ancient, foundational identity.

Unraveling the Nazi Influence Rumors

Among the various theories and discussions surrounding why Persia became Iran, one persistent rumor points to a connection with Nazi Germany. It is widely believed that the name change came directly from Iran’s relationship with Germany during the 1930s. The suggestion is that Nazi Germany, with its own emphasis on "Aryan" racial purity, would have supported this more nationalist name over one that was technically foreign (Persia, derived from Greek). This theory posits that the German government might have encouraged Reza Shah to formalize the use of "Iran" to align with their own ideological framework and foster closer ties. While there are several stories and rumors about why Persia finally insisted on being called Iran by outsiders, the alleged Nazi influence remains a notable, albeit debated, aspect. Historical records indicate that Iran, under Reza Shah, pursued a policy of neutrality and sought to balance its relationships with various world powers, including Germany, to avoid domination by Britain or Russia. However, the perceived affinity between the "Aryan" concept in Iran and the Nazi ideology of "Aryan supremacy" led to suspicions and, later, accusations of pro-Axis leanings, which ultimately contributed to the Allied invasion of Iran in 1941. During this subsequent occupation, Reza Shah was deposed and replaced by his young son, Mohammad Reza Pahlavi, in part to secure Iranian oil fields and ensure Allied supply lines (the "Persian Corridor"). While direct evidence of a German *insistence* on the name change is scarce, the circumstantial alignment of nationalist and "Aryan" ideologies certainly fueled these rumors and remains a part of the complex narrative surrounding the 1935 decision.

The Aftermath: Persia, Iran, and the Shifting Sands of Identity

The 1935 name change was a significant step, but the journey of the nation's identity, and how it was perceived globally, did not end there. The decades that followed saw further shifts and nuances in the usage of "Persia" and "Iran," reflecting evolving political landscapes and scholarly discourse.

The 1959 Reversal: A Dual Identity

Despite the official decree of 1935, the name "Persia" continued to be used informally by many, especially in Western circles, due to its deep historical entrenchment. Recognizing this enduring usage and perhaps aiming for greater flexibility, Iran's then-President, Mohammad Reza Pahlavi (Reza Shah's son), made a significant statement in 1959. He declared that the country could be referred to as either "Persia" or "Iran." This move was notably influenced by the work of Professor Ehsan Yarshater, the esteemed editor of *Encyclopedia Iranica*, who propagated a move to use "Persia" and "Iran" interchangeably. This approach was approved by Mohammad Reza Shah, effectively allowing for a dual nomenclature that acknowledged both the historical Western usage and the indigenous name. While the official name remained "Iran," this pragmatic decision aimed to bridge the gap between internal and external perceptions.

The Enduring Legacy: "Iran" Post-1979

Even after another monumental name change in 1979, when the country became the Islamic Republic of Iran following the Iranian Revolution, the majority of people, both within the country and internationally, continued to refer to it simply as "Iran." This persistence reflects a blend of historical continuity, national pride, and practical usage. The addition of "Islamic Republic" signifies a profound ideological shift in governance, but the core geographical and national identity, "Iran," remained steadfast. The journey from "Persia" to "Iran" and its subsequent variations underscores a nation constantly defining and redefining itself, yet always anchored by its ancient, self-chosen name. The story of Iran, known to the Western world for centuries as Persia, encompasses an enormous expanse of time, and, of course, this ancient story is still unfolding today.

Cultural and Linguistic Echoes: The Enduring Persian Language

While the country's official name shifted, the cultural and linguistic heritage associated with "Persia" has remained vibrant and widespread. The Persian language, known natively as Farsi, is spoken today not only in Iran but also in Tajikistan (where it's known as Tajik) and Afghanistan (as Dari). Historically, Persian was a more widely understood language, serving as a lingua franca in a large area ranging from the Middle East to India. Its influence on literature, art, and science across these regions is immense, shaping the cultural tapestry of a vast geographic expanse. It's important to distinguish between the name of the country and the name of its dominant language. Even though the country is officially "Iran," the language is still widely referred to as "Persian." This linguistic continuity is a testament to the enduring power of the cultural legacy associated with the historical term "Persia." The rich poetic traditions of Rumi, Hafez, and Saadi, the intricate designs of Persian carpets, and the exquisite Persian miniature paintings are all part of this heritage, transcending the political decisions about national nomenclature. The language serves as a living bridge to the glorious past, ensuring that the essence of "Persia" continues to thrive within "Iran."

Beyond the Name: What "Iran" Signifies Today

The transition from "Persia" to "Iran" in 1935 was more than a mere administrative update; it was a profound act of national self-determination. It represented a deliberate effort by Reza Shah Pahlavi to align the nation's external identity with its internal reality, reconnecting it with its ancient Aryan roots and forging a modern national identity. This decision aimed to shed the colonial and orientalist connotations that "Persia" had acquired in the Western imagination, asserting the country's autonomy and its right to define itself. Today, "Iran" stands as a testament to a nation's enduring spirit, blending a rich, glorious past with a complex, unfolding present. The name encapsulates millennia of history, from the Achaemenid Empire to the Sassanids, and through various dynasties to the modern Islamic Republic. It signifies a continuous cultural thread, a vibrant language, and a people deeply proud of their heritage. The story of why Persia became Iran is a compelling narrative of identity, sovereignty, and the persistent quest for self-definition on the global stage. It reminds us that names carry immense weight, embodying history, aspiration, and the very soul of a nation. What are your thoughts on this significant historical shift?
