In 539 BCE, Cyrus the Great entered Babylon without a battle. The city, one of the ancient world's greatest, had been the capital of an empire for centuries. Its surrender — engineered through political maneuvering as much as military force — gave Cyrus control of Mesopotamia and made him the ruler of the largest empire the world had seen. His response, recorded in the Babylonian text known as the Cyrus Cylinder, was to proclaim himself not a foreign conqueror but a liberator chosen by the Babylonian god Marduk, to restore the city's exiled populations, and to return to their temples the cult statues that the previous king Nabonidus had removed. Among those allowed to return home were the Jewish exiles from Judah, captive in Babylon since Nebuchadnezzar's conquest a half-century earlier. The Hebrew prophet known as Deutero-Isaiah called Cyrus "messiah" — the anointed one of the God of Israel.
This is the paradox at the heart of ancient Persia: a succession of empires that at their greatest controlled territories from Egypt to India, crushed rebellions with devastating force, and extracted tribute from dozens of subject peoples — yet whose cultural memory, in the West and in Iran alike, is saturated with images of enlightened governance, cultural tolerance, and civilizational achievement. The Achaemenid Empire (550-330 BCE), the Parthian Empire (247 BCE-224 CE), and the Sassanid Empire (224-651 CE) formed three successive expressions of a Persian civilization that survived conquest by Macedonians and Arabs and left imprints on Judaism, Christianity, Islam, Greek philosophy, Roman military history, and the cultural identity of the modern Iranian state.
Understanding ancient Persia means navigating between Greek-sourced narratives that long dominated Western historiography, the fragmentary evidence of Persian-language sources, and the intensely politicized use of Achaemenid imagery in modern Iranian nationalism.

The Achaemenid Empire: Founding and Structure
Cyrus the Great and the Art of Conquest
Cyrus II came from the small Persian kingdom of Anshan in the region of Fars in southern Iran. He was, by birth, a vassal of the Median Empire. His revolt against his Median overlord Astyages around 550 BCE succeeded partly through defections within the Median army — including, according to Herodotus, Astyages's own general. From this initial success, Cyrus moved with remarkable speed: Lydia (modern western Turkey, then one of the wealthiest kingdoms in the world) fell around 547 BCE, and Babylon in 539 BCE.
What distinguished Cyrus from most conquerors of his era was his approach to legitimacy in conquered territories. The Assyrian Empire, which had dominated the Near East in the centuries before the rise of Persia, had practiced systematic deportation of conquered populations — a policy of deliberate cultural destruction and social disruption intended to prevent organized resistance. Cyrus did the opposite. In Babylon, he presented himself as the chosen of Marduk, the chief Babylonian deity. In the Hebrew tradition, he was the anointed of the God of Israel. In each conquered territory, he sought to position himself within the existing religious and cultural framework rather than replacing it.
The Cyrus Cylinder records his release of peoples deported to Babylon, his restoration of cult images to their home temples, and his respect for Babylonian religious practice. It has been celebrated in modern times as the world's first human rights charter — a claim actively promoted by the Pahlavi monarchy in Iran and adopted by the United Nations, which displayed a replica of the cylinder in its New York headquarters. Most ancient historians regard this characterization as anachronistic. The cylinder is recognizably a standard genre of Mesopotamian royal inscription — the "good king" propaganda that legitimized conquest by framing it as liberation from a bad predecessor. But the actual policies it describes, whatever their motivations, were more tolerant than those of most ancient conquerors.
Darius and the Administrative Revolution
Darius I (reigned 522-486 BCE) came to power through a violent and contested succession that he justified and documented in the extraordinary Behistun inscription, carved into a cliff face on the road from Babylon to Ecbatana. Written in three languages — Old Persian, Elamite, and Babylonian — it records Darius's suppression of rebellions across the empire and was the key text that allowed scholars in the 19th century to decipher cuneiform writing.
Having consolidated his control, Darius created the administrative architecture that made the Achaemenid Empire function at its immense scale. The satrapy system divided the empire into approximately 20-30 provinces. Tribute quotas were standardized. Royal inspectors — "the eyes and ears of the king" — traveled continuously, evaluating satrap conduct and reporting to the center. Darius standardized coinage (the gold daric and silver siglos) across the empire, facilitating trade and tribute payment.
The Royal Road stretched approximately 2,700 kilometers from Sardis on the Aegean coast to Susa, the administrative capital. Royal courier stations were spaced a day's ride apart, enabling messages to traverse the entire road in approximately seven days. This communications infrastructure made coordinated administration of an empire spanning three continents possible for the first time.
Darius also began construction of Persepolis — "the Persian city" in Greek — on a high terrace in the Fars region. The complex, completed by his successors Xerxes and Artaxerxes I, included the Apadana (an audience hall capable of holding thousands), the Hall of a Hundred Columns, royal residences, treasuries, and storehouses. The Apadana's processional stairways are decorated with elaborate relief sculptures depicting delegations from 23 subject nations bringing tribute — a deliberate visual statement of imperial reach. The nations depicted include Medes, Elamites, Babylonians, Lydians, Egyptians, Indians, Nubians, and others, each shown in their distinctive dress and bearing characteristic gifts.
Persia and Greece: The Wars from the Persian Side
The Ionian Revolt and Its Aftermath
The Greco-Persian Wars are among the most mythologized conflicts in Western historical memory. They are also among the most one-sidedly documented: virtually all our detailed evidence comes from Greek sources, primarily Herodotus's Histories. The Persian perspective must be assembled from inscriptions, administrative records, and inference.
The trigger for Persian military intervention in mainland Greece was the Ionian Revolt (499-493 BCE), in which Greek city-states on the Aegean coast of Anatolia — long-established Persian subjects — revolted against Persian rule. Athens and Eretria sent ships and soldiers to support the rebels. The revolt was suppressed after six years, and Darius responded to Athenian and Eretrian support by sending an expedition to Greece in 490 BCE.
This expedition — the campaign that ended at the Battle of Marathon — was from the Persian perspective a limited punitive operation against rebellious subjects' supporters, not an attempt to conquer all of Greece. The Athenian victory at Marathon, celebrated in Greek tradition as a defining moment of Athenian greatness, was a significant setback but not a catastrophic defeat for the Persian Empire. Darius died before he could organize a follow-up campaign; it was left to his son Xerxes.
Xerxes and the Great Invasion
Xerxes's invasion of 480 BCE was a massive undertaking by ancient standards — Herodotus gives fanciful figures of 1.7 million soldiers, but modern estimates suggest a force of perhaps 200,000-300,000. The campaign crossed the Hellespont on a bridge of boats and moved along the northern Greek coast. The Battle of Thermopylae, in which the Spartan king Leonidas and 300 Spartans (along with thousands of other Greeks) held the narrow pass for three days before being outflanked, has become the most mythologized engagement in Western military history.
From the Persian perspective, Thermopylae was a tactical success (the pass was taken) and the campaign proceeded as planned. Athens was captured and burned. The decisive setback came at the naval Battle of Salamis, where the combined Greek fleet, in a confined strait, defeated the larger Persian navy. Xerxes returned to Persia, leaving a land army under Mardonius that was defeated at Plataea the following year (479 BCE).
These events did not threaten the existence of the Persian Empire. Persia retained its Anatolian territories and continued to intervene effectively in Greek politics for decades, funding whichever Greek city-state suited Persian interests at any given moment. The Persian Wars' significance in Western historiography as a clash of civilizations — Greek freedom versus oriental despotism — was largely a 19th-century European construction, shaped by European colonial anxieties and classical education that drew direct parallels between Greek resistance to Persia and European resistance to what was imagined as Eastern despotism. Iranian scholarship has consistently challenged this framing.
Zoroastrianism: The Religion of Light
Zarathustra and His Teaching
Zoroastrianism's founder, known in the ancient Iranian language of Avestan as Zarathustra (the Greek Zoroaster), is one of the most influential religious figures in history whose biography remains almost entirely uncertain. Proposed dates for his life range from approximately 1500-1200 BCE (based on linguistic analysis of the Gathas, the oldest Zoroastrian hymns) to the 7th-6th centuries BCE (based on classical sources placing him 258 years before Alexander). His birthplace is similarly disputed.
What is clear from the Gathas — seventeen hymns composed in an archaic form of Avestan and attributed to Zarathustra himself — is the outlines of his theological revolution. He proclaimed Ahura Mazda as the supreme and only worthy God (the earlier Iranian pantheon, shared with Vedic Indian religion, was de-emphasized or demonized). He defined the fundamental cosmic opposition as between asha (truth, righteousness, cosmic order) and druj (falsehood, evil, chaos). Human beings possess free will and must choose between these principles in thought, word, and deed.
The Cosmic Drama and the Afterlife
Zoroastrian theology frames history as a cosmic drama of approximately 12,000 years divided into epochs, during which Ahura Mazda and the opposing principle Angra Mainyu (also called Ahriman) struggle for dominance. At the end of time (Frashokereti), there will be a final renovation of the world: the dead will be resurrected, all souls will be judged, evil will be destroyed, and creation will be purified and perfected.
Individual souls, after death, cross the Chinvat Bridge (the Bridge of the Requiter). The righteous cross safely to paradise (Vahisht); the wicked fall into the realm of the worst mind (Druj-deman). The mechanisms here — individual judgment after death, paradise and hell, bodily resurrection, apocalyptic end of history, a future savior (Saoshyant) — parallel doctrines that appear in Second Temple Judaism, Christianity, and Islam, and scholars have extensively debated the degree to which Persian-Zoroastrian influence shaped these later traditions during the period of Jewish exile in Babylon and Persian political dominance of the Near East.
Fire Temples and the Modern Zoroastrian Community
Sacred fire — burning continuously in fire temples as a symbol of Ahura Mazda's light — is central to Zoroastrian practice. Zoroastrians do not worship the fire itself but use it as a symbol of the divine. This distinction was frequently lost on outside observers, leading to the label "fire-worshippers" that persisted in Islamic and European descriptions.
After the Arab Muslim conquest of the Sassanid Empire in the 7th century CE, Zoroastrians in Iran faced gradual discrimination and conversion pressure. A community fled to India, eventually settling on the Gujarat coast, and became known as the Parsis (Persians). The Parsi community in Mumbai has produced remarkable figures in Indian business, arts, and science. The global Zoroastrian population today is estimated at 100,000-200,000.
Alexander's Conquest and the End of Achaemenid Persia
The Macedonian Campaigns
Alexander III of Macedon crossed into Persian territory in 334 BCE with an army of approximately 37,000. Over thirteen years of continuous campaigning, he defeated the last Achaemenid king Darius III at three major engagements — Granicus, Issus, and Gaugamela — captured the Persian royal capitals, and pushed his army as far east as the Indus River. He died in Babylon in 323 BCE at age 32, without having designated a successor.
The burning of Persepolis in 330 BCE — whether deliberate or accidental, whether political statement or drunken impulse — destroyed one of the ancient world's great architectural monuments and a vast archive of Achaemenid administrative records. The ancient accounts are contradictory and the truth is probably irrecoverable. What is clear is that the destruction was symbolically significant: it represented the deliberate erasure of the Achaemenid royal heritage.
Alexander's relationship with Persian culture was more complex than the bonfire suggests. He adopted Persian royal dress and court ceremony, incorporated Persian nobles into his administration, and attempted to fuse Macedonian and Persian elites through the mass marriages at Susa in 324 BCE, at which he and approximately 90 of his officers married Persian and Median women.
The Parthian and Sassanid Continuation
Persian cultural identity proved far more durable than the Achaemenid dynasty. The Parthian Empire, founded by the Iranian Parni tribe in 247 BCE, displaced the Seleucid (Macedonian) successor state from the Iranian plateau. The Parthians ruled for nearly 500 years, during which time they fought Rome to a standstill, inflicting one of Rome's worst defeats at Carrhae in 53 BCE. The Parthian capital at Ctesiphon near modern Baghdad became one of the ancient world's greatest cities.
The Sassanid Empire (224-651 CE) overthrew the Parthians and explicitly presented itself as a restoration of the Achaemenid tradition. The Sassanids revived Zoroastrianism as a state religion, engaged in monumental building programs, and engaged in sustained military competition with Rome and then Byzantium for four centuries. The Byzantine-Sassanid wars of the early 7th century CE — which exhausted both empires — prepared the ground for the rapid Arab Muslim conquest that followed.
The Persian Language and Cultural Continuity
The survival of the Persian language through the Arab conquest is one of the most remarkable facts in cultural history. While Arabic became the language of religion, administration, and high culture across much of the Islamic world, Persian survived and eventually flourished as a literary language. The period from the 9th through the 13th centuries is sometimes called the Persian Renaissance: poets including Rudaki, Ferdowsi, Omar Khayyam, Rumi, and Hafez wrote in Persian within an Islamic framework and produced works that are among the greatest in world literature.
Ferdowsi's Shahnameh (finished around 1010 CE), composed in Persian with minimal Arabic vocabulary, was an explicit act of cultural preservation. Ferdowsi spent approximately 30 years on the poem, drawing on pre-Islamic chronicles and oral tradition to narrate the mythological kings from Keyumars (the first man) through Yazdegerd III (the last Sassanid king). The Shahnameh is not merely antiquarian: it established norms of Persian literary language, transmitted pre-Islamic cultural memory, and articulated an Iranian national identity that would survive the Islamic period.
Modern Iranian Nationalism and the Achaemenid Legacy
The Pahlavi dynasty (1925-1979) made extensive and deliberate use of Achaemenid imagery as a legitimating strategy. Reza Shah changed the country's name from Persia to Iran in 1935, emphasizing the connection to the ancient Iranian identity. His son Mohammad Reza Shah's 1971 celebration of the 2,500th anniversary of the Persian Empire — staged at Persepolis with heads of state from around the world, a feast catered by Maxim's of Paris, and elaborate pageantry connecting the Shah to Cyrus the Great — was simultaneously a remarkable display of civilizational pride and a political miscalculation. Religious conservatives saw it as glorification of a pre-Islamic, pagan past; the extravagance inflamed public opinion in a country with significant poverty. The celebrations contributed to the political dynamics that led to the 1979 Islamic Revolution.
The Islamic Republic officially rejected the cult of the pre-Islamic past, but Iranian cultural identity has proven stubborn. Nowruz (Persian New Year) continued to be celebrated through the Islamic Republic despite early clerical discomfort. The Shahnameh remains a national cultural touchstone. Archaeological sites including Persepolis are maintained and promoted as tourist attractions. Cyrus and Darius continue to appear in Iranian popular culture in ways that the official ideology of the Islamic Republic cannot fully suppress.
The Cyrus Cylinder debate continues to reflect these political investments. Iranian diaspora communities and Iranian nationalists tend to embrace the "first human rights charter" interpretation precisely because it places Iranian civilization at the origin of what the modern world values most. Critical historians point out that this interpretation projects modern concepts onto an ancient text that was doing something quite different. Both sides of this debate are, to some degree, using the ancient past to argue about the present.

Frequently Asked Questions
Who was Cyrus the Great and what made the Achaemenid Empire distinctive?
Cyrus II of Persia, known as Cyrus the Great, founded the Achaemenid Empire in approximately 550 BCE when he conquered the Median Empire, which had been ruled by his maternal grandfather Astyages. He subsequently conquered Lydia (the kingdom of the legendarily wealthy Croesus) around 547 BCE and Babylon in 539 BCE. At its greatest extent under his successors, the Achaemenid Empire stretched from the Aegean coast of Anatolia and Egypt in the west to the Indus Valley in the east, encompassing a territory of approximately 5.5 million square kilometers — the largest empire the world had seen to that point.Cyrus's reputation in ancient sources is remarkably positive for a conqueror. He is the only non-Jewish figure in the Hebrew Bible to be called 'messiah' (anointed one), in the book of Isaiah, for his edict allowing the Jewish exiles in Babylon to return to their homeland and rebuild the Temple in Jerusalem. Greek sources, including Xenophon's romanticized biography the Cyropaedia, depict him as a model ruler. This largely positive image is associated with a policy of respecting local religions and customs in conquered territories, rather than the forced cultural homogenization practiced by the Assyrian Empire before him.The Cyrus Cylinder, a clay artifact discovered in Babylon in 1879, has become one of the most discussed documents from the ancient world. Inscribed in Babylonian cuneiform, it records Cyrus's capture of Babylon and his restoration of local temples and deportees. Since the mid-20th century it has been promoted by some — including the government of the Pahlavi dynasty in Iran — as the world's first declaration of human rights. Most ancient historians dispute this characterization, arguing that it was standard Mesopotamian royal propaganda legitimizing conquest by presenting it as liberation. The debate over the Cyrus Cylinder reflects modern political investments in ancient history as much as it reflects the ancient document itself.
How did Darius I organize the Persian Empire and why was Persepolis significant?
Darius I (reigned 522-486 BCE) inherited an empire wracked by rebellions following a contested succession after Cyrus's son Cambyses II died. His response was both military — he suppressed rebellions across the empire, recording his victories on the trilingual Behistun inscription carved into a cliff face in what is now western Iran — and administrative. Darius created the sophisticated governance structure that defined the Achaemenid Empire at its maturity.The satrapy system divided the empire into approximately 20-30 provinces, each governed by a satrap (from the Old Persian for 'protector of the kingdom') who was typically a Persian nobleman, often a member of the royal family. Satraps collected tribute, maintained order, and administered justice, but their power was checked by royal secretaries and military commanders who reported independently to the king, and by royal inspectors called 'the eyes and ears of the king' who traveled the empire evaluating the satraps' conduct.Darius constructed the Royal Road, a road system approximately 2,700 kilometers long running from Sardis on the Aegean coast to Susa, the administrative capital. Royal couriers using relay stations could cover this distance in approximately seven days, enabling rapid communication across an empire that would otherwise take months to cross. Herodotus's description of these couriers — 'Neither snow nor rain nor heat nor darkness of night prevents these couriers from completing their designated stages with utmost speed' — was later adopted as an unofficial motto by the United States Postal Service.Persepolis, begun by Darius around 518 BCE and continued by his successors, was the empire's ceremonial capital. Its Apadana (audience hall) could hold thousands of people; its staircase reliefs depicted delegations from across the empire's subject nations bringing tribute — a visual encyclopedia of the ancient world's diversity. Persepolis was not primarily a functioning city but a ritual space for the celebration of Nowruz (Persian New Year) and royal ceremony. When Alexander the Great burned it in 330 BCE — whether deliberately or accidentally remains debated — he destroyed one of the ancient world's greatest architectural achievements.
What is the Persian perspective on the Greco-Persian Wars?
The Greco-Persian Wars (499-449 BCE) are among the most written-about conflicts in Western historical tradition, but the historical record is almost entirely Greek. Herodotus, whose Histories is the primary ancient source, was Greek. The accounts of Thermopylae (480 BCE), Marathon (490 BCE), and Salamis (480 BCE) that have entered Western cultural consciousness come from the perspective of the Greek city-states that successfully resisted Persian expansion. The Persian perspective must be reconstructed from fragmentary evidence: royal inscriptions, administrative records, and archaeology.From the Achaemenid imperial perspective, the Greek campaigns were part of a larger project of western expansion and the suppression of rebellion. The Ionian Revolt (499-493 BCE), in which Greek city-states on the Aegean coast of Anatolia — Persian subjects — revolted with Athenian support, preceded the Persian invasion of mainland Greece. Darius's campaign of 490 BCE (which ended at Marathon) and Xerxes's massive invasion of 480 BCE were, in imperial terms, punitive expeditions against rebellious subjects and their backers, not a world-historical clash between East and West freedom.The Greek victories at Thermopylae (a Persian strategic success despite the famous Spartan stand), Salamis, and Plataea did not threaten the Persian Empire's existence. Persia retained its Aegean territories and remained the dominant power in the region for another century and a half. The wars were at the periphery of a vast empire and did not register as a catastrophic defeat in the way that Greek and later Western historiography has presented them.Modern Iranian scholarship and popular culture have complicated the heroic Western framing. Films like the 2007 movie '300,' which depicted Persians as demonic figures, generated significant protests in Iran. Iranian historians point out that Xerxes's army was multi-ethnic — including Egyptians, Babylonians, and many other subject peoples — and that the conflict cannot be straightforwardly mapped onto a modern civilization-of-the-West-versus-Oriental-despotism narrative that was constructed largely in 19th-century European historiography influenced by the political anxieties of that era.
What is Zoroastrianism and how did it influence later religions?
Zoroastrianism is the religion founded by the prophet Zarathustra (known in Greek as Zoroaster), whose dates are disputed among scholars — proposed dates range from as early as 1500-1000 BCE to as late as 600 BCE. The religion centers on the worship of Ahura Mazda, the 'Wise Lord,' the supreme deity of truth and light, and frames cosmic history as a struggle between Ahura Mazda and Angra Mainyu (also called Ahriman), the principle of evil, destruction, and falsehood. Human beings have free will and must choose between truth (asha) and falsehood (druj). At the end of time, good will triumph, the dead will be resurrected and judged, and the world will be purified.This theological structure — a supreme good God, an opposing principle of evil, human moral agency, judgment of the dead, bodily resurrection, and an apocalyptic end of history — is widely regarded by scholars of religion as having been highly influential on the development of Second Temple Judaism (roughly 6th-1st centuries BCE) during and after the Babylonian exile, when Jewish communities were in sustained contact with Persian culture. These ideas subsequently entered Christianity and Islam.The specific Zoroastrian doctrines that appear to parallel later Abrahamic religion include: the figure of Satan as a cosmic adversary (compare Angra Mainyu), the concept of heaven and hell as reward and punishment after death (Zoroastrian texts describe the Bridge of the Requiter over which souls cross after death, going to paradise or falling into hell), angels and demons as cosmic functionaries, and the expectation of a future savior figure (Saoshyant in Zoroastrianism). The degree to which these are direct borrowings versus parallel development from shared earlier sources is debated among scholars.Zoroastrianism's sacred fire temples, in which a sacred flame burns continuously as a symbol of Ahura Mazda's light, continue to function. Today's Zoroastrians number approximately 100,000-200,000 worldwide. The largest community, the Parsis, fled to India following the Arab Muslim conquest of Persia in the 7th century CE and established communities primarily in Gujarat and Mumbai. A smaller but significant community remains in Iran.
How did Alexander the Great's conquest affect Persia and why did it matter?
Alexander III of Macedon crossed the Hellespont into Achaemenid territory in 334 BCE with an army of approximately 37,000 men. His campaigns over the following decade destroyed the Achaemenid Empire at stunning speed. He defeated Darius III at the battles of Granicus (334 BCE), Issus (333 BCE), and Gaugamela (331 BCE) — three engagements that effectively ended Persian imperial resistance. He captured and sacked Persepolis in 330 BCE. The burning of Persepolis, the symbolic heart of Persian royal power, was reported by ancient sources as retribution for Xerxes's burning of Athens 150 years earlier, though some accounts suggest it began as a drunken act at a party rather than a deliberate political statement. The debate among ancient sources mirrors the uncertainty about whether Alexander was a deliberate culture-destroyer or a conqueror who respected Persian traditions.Alexander's attitude toward Persia was complex and contradictory. He adopted Persian court dress, incorporated Persian nobles and soldiers into his army and administration, and attempted to fuse Macedonian and Persian aristocracies — a policy of cultural integration (proskynesis, the Persian court prostration, caused a scandal among his Macedonian officers). He married Roxana, a Bactrian princess, and encouraged his officers to marry Persian women at the famous mass marriage ceremony at Susa in 324 BCE.After Alexander's death in 323 BCE, his empire was divided among his generals (the Diadochi). The Iranian plateau eventually came under the control of the Seleucid Empire, founded by Seleucus. But Persian culture proved more durable than its Macedonian conquerors. The Parthian Empire (247 BCE - 224 CE), founded by the Iranian Parni tribe, gradually displaced Seleucid power and presented itself as a restoration of Persian tradition. The Parthians fought Rome to a standstill for centuries, inflicting one of Rome's worst defeats at the Battle of Carrhae (53 BCE). The Sassanid Empire (224-651 CE) that followed was explicitly a revival of Achaemenid Persian tradition and became Rome's and then Byzantium's most formidable eastern rival for four centuries.
How did Persian cultural identity survive the Arab conquest?
The Arab Muslim conquest of the Sassanid Persian Empire occurred between 633 and 651 CE, ending approximately 400 years of Sassanid rule and the state patronage of Zoroastrianism. Within decades, the Persian administrative class converted to Islam and Persian intellectual life was reconstituted within an Islamic framework. This might have resulted in the dissolution of Persian cultural distinctiveness, as happened in other regions conquered by the early Islamic expansion. It did not.The survival of the Persian language is the most significant fact. Unlike Egypt, where the indigenous Coptic language was gradually replaced by Arabic, or the Maghreb, where Berber receded dramatically, Persian not only survived but became one of the major literary and intellectual languages of the Islamic world. The Abbasid Caliphate (750-1258 CE), which displaced the Arab Umayyads, was heavily shaped by Persian administrative culture; Persian bureaucrats, scholars, and literary figures played central roles in what is called the Islamic Golden Age.The 10th-century Persian poet Ferdowsi spent approximately 30 years composing the Shahnameh (Book of Kings), an epic poem of around 50,000 couplets narrating the mythological and historical Persian kings from creation to the Arab conquest. Written in Persian with minimal Arabic vocabulary, the Shahnameh was an explicit act of cultural preservation and assertion. It remains one of the defining works of Persian literature and is regarded as having preserved the Persian language.Modern Iranian nationalism has maintained a complex relationship with the pre-Islamic Persian past. The Pahlavi dynasty (1925-1979) made extensive use of Achaemenid imagery — official ceremonies were held at Persepolis, and Reza Shah changed the country's official name from Persia to Iran (from 'Aryan') in 1935 as part of a nationalist modernization program. The 1971 celebrations of the 2,500th anniversary of the Persian Empire, held at Persepolis by Mohammad Reza Shah, were simultaneously a grand display of national pride and a political act that alienated religious conservatives who saw them as glorifying a pre-Islamic past.
