The Persian Empire was a series of historical empires that ruled over the Iranian plateau (Irān - "Land of the Aryans") and beyond. Generally, the earliest entity considered a part of the Persian Empire is Persia's Achaemenid dynasty (648–330 BC), a united Aryan kingdom that originated in the region now known as Pars province of Iran and was formed under Cyrus the Great. Successive states in Iran prior to March, 1935 are collectively called the Persian Empire by Western historians.


Persia has long been used by the West to describe the nation of Iran, its people, and its ancient empires. It derives from the ancient Greek name for Iran's maritime province, called Fars in the modern Persian language, Pars in Middle Persian and Pārsā in Old Persian, a word meaning "above reproach". Persis is the Hellenized form of Pars, and through the Latinized word Persia, the other European nations came to use this word for the region.

This area was the core of the original Persian Empire. Most foreigners referred to the state as Persia until March 21, 1935, when Reza Shah Pahlavi formally asked the international community to call the country Iran; which was often used by the Aryan tribes who formed the country in the Achaemenid era united the plateau in that region.

The earliest known record of the Persians comes from an Assyrian inscription from c. 844 BC that calls them the Parsu (Parsuash, Parsumash) and mentions them in the region of Lake Urmia alongside another group, the Madai ( Medes). For the next two centuries, the Persians and Medes were at times tributary to the Assyrians. The region of Parsuash was annexed by Sargon of Assyria around 719 BC. Eventually the Medes came to rule an independent Median Empire, and the Persians were subject to them.

The Achaemenids were the first to create a centralized state in Persia, founded by Achaemenes (Hakhamanish), chieftain of the Persians around 700 BC.

Around 653 BC, the Medes came under the domination of the Scythians, and Teispes, the son of Achaemenes, seems to have led the nomadic Persians to settle in southern Iran around this time — eventually establishing the first organized Persian state in the important region of Anshan as the Elamite kingdom was permanently destroyed by the Assyrian ruler Ashurbanipal (640 BC). The kingdom of Anshan and its successors continued to use Elamite as an official language for quite some time after this, although the new dynasts spoke Persian, an Indo-Iranian tongue.

Teispes' descendants branched off into two lines, one line ruling in Anshan, while the other ruled the rest of Persia. Cyrus II the Great united the separate kingdoms around 559 BC. At this time, the Persians were still tributary to the Median Empire ruled by Astyages. Cyrus rallied the Persians together, and in 550 BC defeated the forces of Astyages, who was then captured by his own nobles and turned over to the triumphant Cyrus, now Shah of a unified Persian kingdom. As Persia assumed control over the rest of Media and their large empire, Cyrus led the united Medes and Persians to still more conquest. He took Lydia in Asia Minor, and carried his arms eastward into central Asia. Finally in 539 BC, Cyrus marched triumphantly into the ancient city of Babylon. After this victory, he set the standard of the benevolent conqueror by issuing the Cyrus Cylinder. In this declaration, the king promised not to terrorize Babylon nor destroy its institutions and culture. Cyrus was killed during a battle against the Massagetae or Sakas.

Cyrus' son, Cambyses II, annexed Egypt to the Achaemenid Empire. The empire then reached its greatest extent under Darius I. He led conquering armies into the Indus River valley and into Thrace in Europe. His invasion of Greece was halted at the Battle of Marathon. His son Xerxes I also tried to subdue the Greeks, but his army was defeated at the Battle of Plataea 479 BC.

The Achaemenid Empire was the largest and most powerful empire the world had yet seen. More importantly, it was well managed and organized. Darius divided his realm into about twenty satrapies (provinces) supervised by satraps, or governors, many of whom had personal ties to the Shah. He instituted a systematic tribute to tax each province. He took the advanced postal system of the Assyrians and expanded it. Also taken from the Assyrians was the usage of secret agents of the king, known as the King's Eyes and Ears, keeping him informed.

Darius built the famous Royal Road by improving ancient trade routes, thereby connecting far reaches of the empire. He moved the administration centre from Fars itself to Susa, near Babylon and closer to the centre of the realm. The Persians allowed local cultures to survive, following the precedent set by Cyrus the Great. This was not only good for the empire's subjects, but ultimately benefited the Achaemenids, since the conquered peoples felt no need to revolt.

It was during the Achaemenid period that Zoroastrianism reached South-Western Iran, where it came to be accepted by the rulers and through them became a defining element of Persian culture. The religion was not only accompanied by a formalization of the concepts and divinities of the traditional (Indo-)Iranian pantheon but also introduced several novel ideas, including that of free will, which is arguably Zoroaster's greatest contribution to religious philosophy. Under the patronage of the Achaemenid kings, and by the 5th century BC as the de-facto religion of the state, Zoroastrianism would reach all corners of the empire. In turn, Zoroastrianism would be subject to the first sycretic influences, in particular from the Semitic lands to the west, from which the divinities of the religion would gain astral and planetary aspects and from where the temple cult originates. It was also during the Achaemenid era that the sacerdotal Magi would exert their influence on the religion, introducing many of the practices that are today identified as typically Zoroastrian, but also introducing doctrinal modifications that are today considered to be revocations of the original teachings of the prophet.

The Achaemenid Empire united people and kingdoms from every major civilization in south west Asia. For the first time in history, people from very different cultures were in contact with one another under one ruler.

Hellenistic Persia (330 BC–150 BC)

The later years of the Achaemenid dynasty were marked by decay and decadence. The greatest empire of the time collapsed in only eight years, when it fell under the attack of a young Macedonian king, Alexander the Great.

The Achaemenid Empire's weakness was exposed to the Greeks in 401 BC, when the Satrap of Sardis hired ten thousand Greek mercenaries to help secure his claim to the imperial throne (see Xenophon, Anabasis). This exposed both the political instability and the military weakness of late Achaemenid State.

Philip II of Macedon, leader of most of Greece, and his son Alexander decided to take advantage of this weakness. After Philip's death, Alexander looked toward Persia. Alexander's army landed in Asia Minor in 334 BC. His armies quickly swept through Lydia, Phoenicia, and Egypt, before defeating all the troops of Darius III at Issus and capturing the capital at Susa. The last Achaemenid resistance was at the "Persian Gates" near the royal palace at Persepolis. The Achaemenid Empire was now in Alexander's hands.

Along his route of conquest, Alexander founded many colony cities, all named "Alexandria". For the next several centuries, these cities served to greatly extend Greek, or Hellenistic, culture in Persia.

Alexander's empire broke up shortly after his death, and Alexander's general, Seleucus I Nicator, tried to take control of Persia, Mesopotamia, and later Syria and Asia Minor. His ruling family is known as the Seleucid Dynasty. However he was killed in 281 BC by Ptolemy Keraunos before he could conquer Greece and Macedonia.

Greek colonization continued until around 250 BC; Greek language, philosophy, and art came with the colonists. Throughout Alexander's former empire, Greek became the common tongue of diplomacy and literature. Trade with China had begun in Achaemenid times along the so-called Silk Road; but during the Hellenistic period it began in earnest. The overland trade brought about some fascinating cultural exchanges. Buddhism came in from India, while Zoroastrianism traveled west to influence Judaism. Incredible statues of the Buddha in classical Greek styles have been found in Persia and Afghanistan, illustrating the mix of cultures that occurred around this time (See Greco-Buddhism), although it is possible that Greco-Buddhist art dates from Achaemenid times when Greek artists worked for the Persians.

The Seleucid kingdom began to decline rather quickly. Even during Seleucus' lifetime, the capital was moved from Seleucia on the Tigris in Mesopotamia to the more Mediterranean Antioch on the Orontes. The eastern provinces of Bactria and Parthia broke off from the Seleucid Kingdom in 238 BC. King Antiochus III's military leadership kept Parthia from overrunning Persia itself, but his successes alarmed the burgeoning Roman Republic. Roman legions began to attack the kingdom. At the same time, the Seleucids had to contend with the revolt of the Maccabees in Judea and the expansion of the Kushan Empire to the east. The empire fell apart and was conquered by Parthia and Rome.

Parthian Confederacy (150 BC–AD 226)

Its rulers, the Arsacid dynasty, belonged to an Iranian tribe that had settled there during the time of Alexander. They declared their independence from the Seleucids in 238 BC, but their attempts to unify Iran were thwarted until after Mithridates I advent to the Parthian throne in about 170 BC.

The Parthian Confederacy shared a border with Rome along the upper Euphrates River. The two polities became major rivals, especially over control of Armenia. Heavily-armoured Parthian cavalry ( cataphracts) supported by mounted archers proved a match for Roman legions, as in the Battle of Carrhae in which the Parthian General Surena defeated Marcus Licinius Crassus of Rome. Wars were very frequent, with Mesopotamia serving as the battleground.

During the Parthian period, Hellenistic customs partially gave way to a resurgence of Persian culture. However, the empire lacked political unity. The administration was shared between Seven Parthian clans who constituted the Dahae Confederation, each of these clans governed a province of the empire. Suren-Pahlav Clan, Karen-Pahlav Clan and Mihran Clan were the most influential ones. By the 1st century BC, Parthia was decentralized, ruled by feudal nobles. Wars with Rome to the west and the Kushan Empire to the northeast drained the country's resources.

Parthia, now impoverished and without any hope to recover the lost territories, was demoralized. The kings had to give more concessions to the nobility, and the vassal kings sometimes refused to obey. Parthia's last ruler Artabanus IV had an initial success in putting together the crumbling state. However, the fate of the Arsacid Dynasty was doomed when in AD 224, the Persian vassal king Ardashir revolted. Two years later, he took Ctesiphon, and this time, it meant the end of Parthia. It also meant the beginning of the third Persian Empire, ruled by the Sassanid kings. Sassanids were from the province of Persis, native to the first Persian Empire, the Achaemenids.

Sassanid Empire (226–651)

Ardashir I, led a rebellion against the Parthian Confederacy in an attempt to revive the glory of the previous empire and to legitimize the hellenized form of Zoroastrianism practised in south western Iran. In two years he was the Shah of a new Persian Empire.

The Sassanid dynasty (also Sassanian) (named for Ardashir's grandfather) was the first dynasty native to the Pars province since the Achaemenids; thus they saw themselves as the successors of Darius and Cyrus. They pursued an aggressive expansionist policy. They recovered much of the eastern lands that the Kushans had taken in the Parthian period. The Sassanids continued to make war against Rome; a Persian army even captured the Roman Emperor Valerian in 260.

The Sassanid Empire, unlike Parthia, was a highly centralized state. The people were rigidly organized into a caste system: Priests, Soldiers, Scribes, and Commoners. Zoroastrianism was finally made the official state religion, and spread outside Persia proper and out into the provinces. There was sporadic persecution of other religions. The Catholic (Orthodox) Christian church was particularly persecuted, but this was in part due to its ties to the Roman Empire. The Nestorian Christian church was tolerated and sometimes even favored by the Sassanids.

The wars and religious control that had fueled The Sassanid empire's early successes eventually contributed to its decline. The eastern regions were conquered by the White Huns in the late 5th century. Adherents of a radical religious sect, the Mazdakites, revolted around the same time. Khosrau I was able to recover his empire and expand into the Christian countries of Antioch and Yemen. Between 605 and 629, Sassanids successfully annexed Levant and Roman Egypt and pushed into Anatolia.

However, a subsequent war with the Romans utterly destroyed the empire. In the course of the protracted conflict, Sassinid armies reached Constantinople, but could not defeat the Byzantines there. Meanwhile, the Byzantine Emperor Heraclius had successfully outflanked the Persian armies in Asia Minor and attacked the empire from the rear while the main Iranian army along with its top Eran Spahbods were far from battlefields. This resulted in a crushing defeat for Sassanids in Northern Mesopotamia. The Sassanids had to give up all their conquered lands and retreat. This defeat was mentioned in Qur'an as a "victory for believers," referring to the Romans, who were monotheists, in contrast to the pagan Sassinids. (Note: The official religion of the Sassanid empire was Zoroastrianism. It is not an Abrahamic/Semitic religion like Christianity or Islam, so it would be classified as "Pagan" by the followers of those religions even though it was monotheistic).

Following the advent of Islam and collapse of Sassanid Empire, Persians came under the subjection of Arab rulers for almost two centuries before native Persian dynasties could gradually drive them out. In this period a number of small and numerically inferior Arab tribes migrated to inland Iran.

Also some Turkic tribes settled in Persia between the 9th and 12th centuries.

In time these peoples were integrated into numerous Persian populations and adopted Persian culture and language while Persians retained their culture with minimal influence from outside.

Islam and Persia (650–1219)

The explosive growth of the Arab Caliphate coincided with the chaos caused by the defeat of Sassanids in wars with the Byzantine Empire. Most of the country was conquered between 643 to 650. Persia's conquest by Islamic Arab armies marks the transition into " medieval" Persia.

Yazdgerd III, the last Sasanian emperor, died ten years after he lost his empire to the newly-formed Muslim Caliphate. He tried to recover some of what he lost with the help of the Turks, but they were easily defeated by Muslim armies. Then he sought the aid of the Chinese Tang dynasty. However, the Chinese help did not avail and Arab muslims ultimately defeated the Chinese forces in the battle of Talas, a century after Yazdgerd's death. He is believed to have lived on the borders of Islamic Persia. Some historians say that he lived inside Islamic Iran.

The Arab empire, ruled by the Umayyad Dynasty, was the largest state in history up to that point. It stretched from the Iberian Peninsula to the Indus River, from the Aral Sea to the southern tip of the Arabian Peninsula. The Umayyads borrowed heavily from Persian and Byzantine administrative systems and moved their capital to Damascus, in the centre of their empire. The Umayyads would rule Persia for a hundred years.

The Arab conquest dramatically changed life in Persia. Arabic became the new lingua franca, Islam eventually replaced Zoroastrianism, and mosques were built. A new language, religion, and culture were added to the Iranian cultural milieu. During this time and because of the vast reaches of the Arab empire, many Persian (Iranian) scholars had a direct impact on the European Renaissance centuries later (See full list here).

In 750 the Umayyads were ousted from power by the Abbasid dynasty. By that time, Persians had come to play an important role in the bureaucracy of the empire ISBN 1-84212-011-5. The caliph Al-Ma'mun, whose mother was Persian, moved his capital away from Arab lands into Merv in eastern Iran. It was he who later founded the House of Wisdom in Baghdad, based on the Iranian Jondishapour.

But political unrest continued. In 819, Samanids carved out an independent state in eastern Persia to become the first native rulers after the Arabic conquest. They made Samarqand, Bukhara and Herat their capitals and revived the Persian language and culture. It was approximately during this age, when the poet Firdawsi finished the Shahnameh, an epic poem retelling the history of the Iranian kings. This epic was completed by 1008 AD.

In 913, western Persia was conquered by the Buwayhid, a Deylamite tribal confederation from the shores of the Caspian Sea. They made the city of Shiraz their capital. The Buwayhids destroyed Islam's former territorial unity. Rather than a province of a united Muslim empire, Iran became one nation in an increasingly diverse and cultured Islamic world.

Turkic rule (1037–1219)

The Muslim world was shaken again in 1037 with the invasion of the Seljuk Turks from the northeast. The Seljuks created a very large Middle Eastern empire. The Seljuks built the fabulous Friday Mosque in the city of Isfahan. The famous Persian mathematician and poet, Omar Khayyám, wrote his Rubaiyat during Seljuk times.

In the early 13th century the Seljuks lost control of Persia to another group of Turks from Khwarezmia, near the Aral Sea. The Shahs of the Khwarezmid Empire ruled for only a short while, however, because they had to face the most feared conqueror in history: Genghis Khan.

Under the Mongols and their successors (1219–1500)

In 1218, Genghis Khan sent ambassadors and merchants to the city of Otrar, on the northeastern confines of the Khwarizm shahdom. The governor of Otrar had these envoys executed. Genghis, out for revenge, sacked Otrar in 1219 and continued on to Samarkand and other cities of the northeast.

Genghis' grandson, Hulagu Khan, finished what Genghis had begun when he conquered Khwarzim Empire, Baghdad, and much of the rest of the Middle East from 1255 to 1258. Iran became the Ilkhanate, a division of the vast Mongol Empire.

In 1295, after Ilkhan Mahmud Ghazan converted to Islam, he renounced all allegiance to the Emperor Chengzong of Yuan China who had recently succeeded his grandfather Kublai Khan as Great Khan. The Ilkhans patronized the arts and learning in the fine tradition of Iranian Islam; indeed, they helped to repair much of the damage of the Mongol conquests.

In 1335, the death of Abu Sa'id, the last well-recognized Ilkhan, spelled the end of the Ilkhanate. Though Arpa Ke'un was declared Ilkhan his authority was disputed and the Ilkhanate was splintered into a number of small states. This left Iran open to still more conquest at the hands of Timur the Lame or Tamerlane, a Central Asian conqueror seeking to revive the Mongol Empire. He invaded Iran beginning around 1370 and plundered the country until his death in 1405. Timur was an even bloodier conqueror than Genghis had been. In Isfahan, for instance, he slaughtered 70,000 people so that he could build towers with their skulls. He conquered a wide area and made his own city of Samarkand rich, but he made no effort to forge a lasting empire. Iran was essentially left in ruins.

For the next hundred years Persia was not a unified state. It was ruled for a while by descendants of Timur, called the Timurid emirs. Toward the end of the 15th century, Persia was taken over by the Emirate of the White Sheep Turkmen (Ak Koyunlu). But there was little unity and none of the sophistication that had defined Iran during the glory days of Islam.

Safavid dynasty (1500–1722)

The Safavid Dynasty hailed from the town of Ardabil in the region of Azarbaijan. The Safavid Shah Ismail I overthrew the White Sheep Turkish rulers of Persia to found a new native Persian empire. Ismail expanded Persia to include all of present-day Azerbaijan, Iran, and Iraq, plus much of Afghanistan. Ismail's expansion was halted by the Ottoman Empire at the Battle of Chaldiran in 1514, and war with the Ottomans became a fact of life in Safavid Iran.

Safavid Persia was a violent and chaotic state for the next seventy years, but in 1588 Shah Abbas I of Safavid ascended to the throne and instituted a cultural and political renaissance. He moved his capital to Isfahan, which quickly became one of the most important cultural centers in the Islamic world. He made peace with the Ottomans. He reformed the army, drove the Uzbeks out of Iran and into modern-day Uzbekistan, and recaptured the island of Hormuz from the Portuguese.

The Safavids were followers of Shi'a Islam, and under them Persia (Iran) became the largest Shi'a country in the Muslim world, a position Iran still holds today.

Under the Safavids Iran enjoyed its last period as a major imperial power. In 1639, a final border was agreed upon with the Ottoman Empire with the Treaty of Qasr-e Shirin; which delineates the border between the Republic of Turkey and Iran and also that of between Iraq and Iran, today.

Persia and Europe (1722–1914)

During this period, Persia became a centre for the manufacture of scientific instruments, retaining its reputation for quality well into the 19th century.

In 1722, the Safavid state collapsed. That year saw the first European invasion of Persia since the time of Alexander: Peter the Great, Emperor of Imperial Russia, invaded from the northwest as part of a bid to dominate central Asia. To make the situation truly hopeless, Ottoman forces accompanied the Russians, successfully laying siege to Isfahan.

The country was able to weather the invasions; neither the Russians nor the Turks gained any territory. However, the Safavids were severely weakened, and that same year (1722), the Afghans launched a bloody battle in response to the Safavids' attempts on trying to forcfully convert them from Sunni to Shi'a sect of Islam. The last Safavid shah was executed, and the dynasty came to an end.

The Persian empire experienced a temporary revival under Nadir Shah in the 1730s and 1740s. Nadir drove out the Russians and confined the Afghans to their present home in Afghanistan. He launched many successful campaigns against Persia's old enemies, the nomadic khanates of Central Asia; most of them were destroyed or absorbed into Persia. However, his empire declined after his death. His rule was followed by the weak and short-lived Zand dynasty. Iran was left unprepared for the worldwide expansion of European colonial empires in the late 18th century and throughout the 19th century.

Persia found relative stability in the Qajar dynasty, ruling from 1779 to 1925, but lost hope to compete with the new industrial powers of Europe; Persia found itself sandwiched between the growing Russian Empire in Central Asia and the expanding British Empire in India. Each carved out pieces from the Persian empire that became Bahrain, Azerbaijan, Turkmenistan, Uzbekistan, and Afghanistan amongst other previous provinces.

Although Persia was never directly invaded, it gradually became economically dependent on Europe. The Anglo-Russian Convention of 1907 formalised Russian and British spheres of influence over the north and south of the country, respectively, where Britain and Russia each created a " sphere of influence", where the colonial power had the final "say" on economic matters.

At the same time Mohammad Ali Shah Qajar had granted a concession to William Knox D'Arcy, later the Anglo-Persian Oil Company, to explore and work the newly-discovered oil fields at Masjid Soleiman in southwest Persia, which started production in 1914. Winston Churchill, as First Sea Lord to the British Admiralty, oversaw the conversion of the Royal Navy to oil-fired battleships and partially nationalized it prior to the start of war. A small Anglo-Persian force was garrisoned there to protect the field from some hostile tribal factions.

World War I and the interbellum (1914–1935)

Persia was drawn into the periphery of World War I because of its strategic position between Afghanistan and the warring Ottoman, Russian, and British Empires. In 1914 Britain sent a military force to Mesopotamia to deny access to the Persian oilfields from the Ottomans. The German Empire retaliated on behalf of its ally by spreading a rumour that Kaiser Wilhelm II of Germany had converted to Islam, and sent agents through Iran to attack the oil fields and raise a Jihad against British rule in India. Most of those German agents were captured by Persian, British and Russian troops who were sent to patrol the Afghan border, and the rebellion faded away. This was followed by a German attempt, assisted by his mainly Swedish bodyguard, to abduct and control Ahmad Shah Qajar, which was foiled at the last moment.

In 1916 the fighting between Russian and Ottoman forces to the north of the country had spilt down into Persia; Russia gained the advantage until most of her armies collapsed in the wake of the Russian Revolution of 1917. This left the Caucasus unprotected, and the Caucasian and Persian civilians starving after years of war and deprivation. In 1918 a small force of 400 British troops under General Dunsterville moved into the Trans-Caucasus from Persia in a bid to encourage local resistance to German and Ottoman armies who were about to invade the Baku oilfields. Although they later withdrew back into Persia, they did succeed in delaying the Turks access to the oil almost until the Armistice. In addition, the expedition’s supplies were used to avert a major famine in the region, and a camp for 30,000 displaced refugees was created near the Mesopotamian frontier.

By World War I, Persia was not the world power it had once been. It had become a tool in the political battles of other empires. In 1919, northern Persia was occupied by the British General William Edmund Ironside to enforce the Turkish Armistice conditions and assist General Dunsterville and Colonel Bicherakhov contain Bolshevik influence (of Mirza Kuchak Khan) in the north. Britain also took tighter control over the increasingly lucrative oil fields.

In 1925, Reza Shah Pahlavi seized power from the Qajars and established the new Pahlavi dynasty, the last Persian monarchy before the establishment of the Islamic Republic. However, Britain and the Soviet Union remained the influential powers in Persia into the early years of the Cold War.

On March 21, 1935, Iran was officially accepted as the new name of the country. After Persian scholars' protests to this decision, in 1953 Mohammad Reza Shah announced both names "Iran" and "Persia" could be used.
