While its conquests were largely successful in most regions, the Achaemenid Empire's attempts to expand into Greece proved extremely difficult over the course of decades of wars and multiple kings, ultimately resulting in its defeat in the Greek mainland.

In 330 BC, amidst a Greek military campaign that began in 336 BC, the Achaemenid Empire was conquered in its entirety by Alexander the Great, who annexed it to his Macedonian Empire.<ref name="Ulrich">{{cite book |author=Wilcken |first=Ulrich |url=https://archive.org/details/alexandergreat00wilc |title=Alexander the Great|publisher=W.W.

Almost a century later, Iranian elites in the central plateau successfully reclaimed power from the Seleucids and established the Parthian Empire, which existed for nearly half a millennium before being succeeded by the Iranian Sasanian Empire.<ref name="book" />

In the modern era, the Achaemenid Empire has been recognized for its centralized bureaucracy and administration; its multicultural policy and religious tolerance, especially under Cyrus; its complex infrastructure projects, such as the Royal Road and an organized postal system; the use of official languages (Persian and Aramaic) across its territories; and the development of a civil service and a large, professional army and navy. Many of these systems were adopted and expanded upon by later empires in the Greco-Roman world and beyond.<ref name="schmitt">{{Encyclopædia Iranica Online|volume=1|fascicle=4|title=Achaemenid Dynasty|last=Schmitt|first=Rüdiger|pages=414–426|url=https://www.iranicaonline.org/articles/achaemenid-dynasty/}}</ref>

The Achaemenid Empire was created by nomadic Persians. The Persians were Iranian people who arrived in what is today Iran {{Circa|1000 BC}} and settled a region including north-western Iran, the Zagros Mountains and Persis alongside the native Elamites.{{sfn|Brosius|2006|p=3}} The Persians were originally nomadic pastoralists in the western Iranian Plateau. The Achaemenid Empire may not have been the first Iranian empire, as the Medes, another group of Iranian people, possibly established a short-lived empire when they played a major role in overthrowing the Assyrians.<ref>{{Cite book|title=A history of the ancient Near East ca. 3000–323 BC|last=Van de Mieroop|first=Marc|isbn=978-1-118-71817-9|edition=Third|location=Chichester, West Sussex, UK|oclc=904507201|date=25 June 2015}}</ref>

The Achaemenids were initially rulers of the Elamite city of Anshan near the modern city of Marvdasht;{{sfn|Briant|2002|p=17}} the title "King of Anshan" was an adaptation of the earlier Elamite title "King of Susa and Anshan".{{sfn|Brosius|2006|p=6}} There are conflicting accounts of the identities of the earliest Kings of Anshan. According to the Cyrus Cylinder (the oldest extant genealogy of the Achaemenids) the kings of Anshan were Teispes, Cyrus I, Cambyses I and Cyrus II, also known as Cyrus the Great, who founded the empire.{{sfn|Briant|2002|p=17}}

The later Behistun Inscription, written by Darius the Great, claims that Teispes was the son of Achaemenes and that Darius is also descended from Teispes through a different line, but no earlier texts mention Achaemenes.{{sfn|Briant|2002|p=16}} In Herodotus' Histories, he writes that Cyrus the Great was the son of Cambyses I and Mandane of Media, the daughter of Astyages, the king of the Median Empire.{{sfn|Briant|2002|p=15}}

Family ties that the Macedonian rulers Amyntas and Alexander enjoyed with Bubares ensured them good relations with the Persian kings Darius and Xerxes I, who was also known as Xerxes the Great. The Persian invasion led indirectly to Macedonia's rise in power and Persia had some common interests in the Balkans; with Persian aid, the Macedonians stood to gain much at the expense of some Balkan tribes such as the Paeonians and Greeks.

===Greco-Persian Wars=== {{Main|Greco-Persian Wars}}

[[File:Greek-Persian duel.jpg|thumb|Greek hoplite and Persian warrior depicted fighting, on an ancient kylix, 5th century BC]] The Ionian Revolt in 499 BC, and associated revolts in Aeolis, Doris, Cyprus, and Caria, were military rebellions by several regions of Asia Minor against Persian rule, lasting from 499 to 493 BC. At the heart of the rebellion was the dissatisfaction of the Greek cities of Asia Minor with the tyrants appointed by Persia to rule them, along with the individual actions of two Milesian tyrants, Histiaeus and Aristagoras. In 499 BC, the then-tyrant of Miletus, Aristagoras, launched a joint expedition with the Persian satrap Artaphernes to conquer Naxos, in an attempt to bolster his position in Miletus, both financially and in terms of prestige. The mission was a debacle, and sensing his imminent removal as a tyrant, Aristagoras chose to incite the whole of Ionia into rebellion against the Persian king, Darius I, who was commonly known as Darius the Great.{{citation needed|date=January 2018}}

The Persians continued to reduce the cities along the west coast that still held out against them, before finally imposing a peace settlement in 493 BC on Ionia that was generally considered to be both just and fair. The Ionian Revolt constituted the first major conflict between Greece and the Achaemenid Empire, and as such represents the first phase of the Greco-Persian Wars. Asia Minor had been brought back into the Persian fold, but Darius had vowed to punish Athens and Eretria for their support of the revolt.<ref>{{cite book |author=West |first=Willis Mason |url=https://archive.org/details/ancientworldfro00westgoog |title=The ancient world from the earliest times to 800 CE |publisher=Allyn and Bacon |year=1904 |page=[https://archive.org/details/ancientworldfro00westgoog/page/n187 137] |quote=The Athenian support was particularly troubling to Darius since he had come to their aid during their conflict with Sparta.}}</ref> Moreover, seeing that the political situation in Greece posed a continued threat to the stability of his Empire, he decided to embark on the conquest of all of Greece.

[[File:Achaemenid king fighting hoplites, Cimmerian Bosphorus intaglio (composite).jpg|thumb|upright=1.5|Achaemenid king fighting hoplites, seal and seal holder, Cimmerian Bosporus.]] Xerxes I (485–465 BC, Old Persian ''Xšayārša'' "Hero Among Kings"), son of Darius I, vowed to complete the job. He organized a massive invasion aiming to conquer Greece. His army entered Greece from the north in the spring of 480 BC, meeting little or no resistance through Macedonia and Thessaly, but was delayed by a small Greek force for three days at Thermopylae. A simultaneous naval battle of Artemisium was tactically indecisive as large storms destroyed ships from both sides. The battle was stopped prematurely when the Greeks received news of the defeat at Thermopylae and retreated. The battle was a tactical victory for the Persians, giving them uncontested control of Artemisium and the Aegean Sea.<ref name="VIII21">Herodotus [https://www.perseus.tufts.edu/hopper/text?doc=Hdt.+8.21 VIII, 21].</ref>

Following his victory at the Battle of Thermopylae, Xerxes sacked the evacuated city of Athens and prepared to meet the Greeks at the strategic Isthmus of Corinth and the Saronic Gulf.

===Cultural phase and Zoroastrian reforms=== After Xerxes I was assassinated, he was succeeded by his eldest surviving son Artaxerxes I. It was during his reign that Elamite ceased to be the language of government,{{citation needed|date=July 2022}} and Aramaic gained in importance. It was probably during this reign that the solar calendar was introduced as the national calendar. Under Artaxerxes I, Zoroastrianism became the ''de facto'' religion of the empire.{{citation needed|date=July 2021}}

After Persia had been defeated at the Battle of Eurymedon (469 or 466 BC<ref>See discussion on possible dates for the battle in the article Battle of the Eurymedon.</ref>), military action between Greece and Persia was halted. When Artaxerxes&nbsp;I took power, he introduced a new Persian strategy of weakening the Athenians by funding their enemies in Greece. This indirectly caused the Athenians to move the treasury of the Delian League from the island of Delos to the Athenian acropolis. This funding practice inevitably prompted renewed fighting in 450&nbsp;BC, where the Greeks attacked at the Battle of Cyprus. After Cimon's failure to attain much in this expedition, the Peace of Callias was agreed between Athens, Argos and Persia in 449&nbsp;BC.<ref>{{Cite web|title=Artaxerxes I Makrokheir (Artaxerxes I) Makrokheir (± 475-± 424) » Stamboom Homs » Genealogy Online|url=https://www.genealogieonline.nl/en/stamboom-homs/I6000000006131531097.php|last=Homs|first=George|website=Genealogy Online|language=en|access-date=2020-05-24}}</ref><ref>{{Cite book|title=Artaxerxes I of Persia|year=2010|isbn=978-613-0-82634-5}}</ref>

When Artaxerxes died in 424 BC at Susa, his body was taken to the tomb already built for him in the Naqsh-e Rustam Necropolis. It was Persian tradition that kings begin constructing their own tombs while they were still alive. Artaxerxes I was immediately succeeded by his eldest and only legitimate son, Xerxes II.{{sfn|Kuhrt|2013|page=880}} However, after a few days on the throne, he was assassinated while drunk by Pharnacyas and Menostanes on the orders of his illegitimate brother Sogdianus, who apparently had gained the support of his regions.

From 412 BC Darius II, at the insistence of Tissaphernes, gave support first to Athens, then to Sparta, but in 407 BC, Darius' son Cyrus the Younger was appointed to replace Tissaphernes and aid was given entirely to Sparta which finally defeated Athens in 404 BC. In the same year, Darius fell ill and died in Babylon. His death gave an Egyptian rebel named Amyrtaeus the opportunity to throw off Persian control over Egypt. At his death bed, Darius' Babylonian wife Parysatis pleaded with him to have her second eldest son Cyrus (the Younger) crowned, but Darius refused. Queen Parysatis favoured Cyrus more than her eldest son Artaxerxes II. Plutarch relates (probably on the authority of Ctesias) that the displaced Tissaphernes came to the new king on his coronation day to warn him that his younger brother Cyrus (the Younger) was preparing to assassinate him during the ceremony. Artaxerxes had Cyrus arrested and would have had him executed if their mother Parysatis had not intervened. Cyrus was then sent back as Satrap of Lydia, where he prepared an armed rebellion. Cyrus assembled a large army, including a contingent of Ten Thousand Greek mercenaries, and made his way deeper into Persia. The army of Cyrus was stopped by the royal Persian army of Artaxerxes II at Cunaxa in 401 BC, where Cyrus was killed. The Ten Thousand Greek Mercenaries including Xenophon were now deep in Persian territory and were at risk of attack. So they searched for others to offer their services to but eventually had to return to Greece.<ref>{{cite book |last1=Brennan |first1=Shane |last2=Thomas |first2=David |title=The Landmark Xenophon's Anabasis |date=2021 |publisher=Pantheon Books |location=New York |isbn=9780307906854}}</ref><ref name=":0" /><ref>Maurice Whittemore Mather (ed.), Joseph William Hewitt (ed.), Xenophon: ''Anabasis, Books 1–4''.

Artaxerxes II was the longest reigning of the Achaemenid kings and it was during this 45-year period of relative peace and stability that many of the monuments of the era were constructed. Artaxerxes moved the capital back to Persepolis, which he greatly extended. Also, the summer capital at Ecbatana was lavishly extended with gilded columns and roof tiles of silver and copper.<ref>(Polybius, 27 October 2012).</ref> The extraordinary innovation of the Zoroastrian shrines can also be dated to his reign, and it was probably during this period that Zoroastrianism spread from Armenia throughout Asia Minor and the Levant. The construction of temples, though serving a religious purpose, was not a purely selfless act, as they also served as an important source of income. From the Babylonian kings, the Achaemenids adopted the concept of a mandatory temple tax, a one-tenth tithe which all inhabitants paid to the temple nearest to their land or another source of income.<ref>{{cite book |last1=Dandamaev |first1=Muhammad A. |last2=Lukonin |first2=Vladimir G. |title=The Culture and Social Institutions of Ancient Iran |date=1989 |publisher=Cambridge University Press |isbn=978-0-521-32107-5 |pages=361–362 }}</ref>

thumb|upright=1.5|Persian Empire timeline including important events and territorial evolution – 550–323 BC Artaxerxes II became involved in a war with Persia's erstwhile allies, the Spartans, who, under Agesilaus II, invaded Asia Minor. To redirect the Spartans' attention to Greek affairs, Artaxerxes II subsidized their enemies: in particular the Athenians, Thebans and Corinthians. These subsidies helped to engage the Spartans in what would become known as the Corinthian War. In 387 BC, Artaxerxes II betrayed his allies and came to an arrangement with Sparta, and in the Treaty of Antalcidas he forced his erstwhile allies to come to terms. This treaty restored control of the Greek cities of Ionia and Aeolis on the Anatolian coast to the Persians while giving Sparta dominance on the Greek mainland. In 385 BC he campaigned against the Cadusians. Although successful against the Greeks, Artaxerxes II had more trouble with the Egyptians, who had successfully revolted against him at the beginning of his reign. An attempt to reconquer Egypt in 373 BC was completely unsuccessful, but in his waning years the Persians did manage to defeat a joint Egyptian–Spartan effort to conquer Phoenicia. He quashed the Revolt of the Satraps in 372–362 BC. He is reported to have had a number of wives. His main wife was Stateira, until she was poisoned by Artaxerxes II's mother Parysatis in about 400 BC. Another chief wife was a Greek woman of Phocaea named Aspasia (not the same as the concubine of Pericles). Artaxerxes II is said to have had more than 115 sons from 350 wives.<ref>{{cite web |date=25 April 2014 |title=The Achaemenid Empire |url=http://iranologie.com/the-history-page/the-achaemenid-empire/ |access-date=21 June 2015}}[http://www.iranologie.com/history/Achaemenid/chapter%20V.html] {{webarchive|url=https://web.archive.org/web/20080619124220/http://www.iranologie.com/history/Achaemenid/chapter%20V.html|date=19 June 2008}}</ref>

In 358 BC Artaxerxes II died and was succeeded by his son Artaxerxes III.

In {{circa|351&nbsp;BC}}, Artaxerxes embarked on a campaign to recover Egypt, which had revolted under his father, Artaxerxes II. At the same time, a rebellion had broken out in Asia Minor, which, being supported by Thebes, threatened to become serious.

Artaxerxes initiated a counter-offensive against Sidon by commanding Belesys, satrap of Syria, and Mazaeus, satrap of Cilicia, to invade the city and to keep the Phoenicians in check. Both satraps suffered crushing defeats at the hands of Tennes, the Sidonese king, who was aided by 40,000 Greek mercenaries sent to him by Nectanebo II and commanded by Mentor of Rhodes. As a result, the Persian forces were driven out of Phoenicia.<ref name="Persianempire"/>

After this, Artaxerxes personally led an army of 330,000 men against Sidon. Artaxerxes' army comprised 300,000-foot soldiers, 30,000 cavalry, 300 triremes, and 500 transports or provision ships. After gathering this army, he sought assistance from the Greeks. Though refused aid by Athens and Sparta, he succeeded in obtaining a thousand Theban heavy-armed hoplites under Lacrates, three thousand Argives under Nicostratus, and six thousand Æolians, Ionians, and Dorians from the Greek cities of Asia Minor. This Greek support was numerically small, amounting to no more than 10,000 men, but it formed, together with the Greek mercenaries from Egypt who went over to him afterward, the force on which he placed his chief reliance, and to which the ultimate success of his expedition was mainly due. The approach of Artaxerxes sufficiently weakened the resolution of Tennes that he endeavoured to purchase his own pardon by delivering up 100 principal citizens of Sidon into the hands of the Persian king and then admitting Artaxerxes within the defences of the town. Artaxerxes had the 100 citizens transfixed with javelins, and when 500 more came out as supplicants to seek his mercy, Artaxerxes consigned them to the same fate. Sidon was then burnt to the ground, either by Artaxerxes or by the Sidonian citizens.

===Second conquest of Egypt=== {{main|Second Achaemenid conquest of Egypt}}

In 343&nbsp;BC, Artaxerxes III, in addition to his 330,000 Persians, had now a force of 14,000 Greeks furnished by the Greek cities of Asia Minor: 4,000 under Mentor, consisting of the troops that he had brought to the aid of Tennes from Egypt; 3,000 sent by Argos; and 1,000 from Thebes. He divided these troops into three bodies, and placed at the head of each a Persian and a Greek. The Greek commanders were Lacrates of Thebes, Mentor of Rhodes and Nicostratus of Argos while the Persians were led by Rhossaces, Aristazanes, and Bagoas, the chief of the eunuchs. Nectanebo II resisted with an army of 100,000 of whom 20,000 were Greek mercenaries. Nectanebo II occupied the Nile and its various branches with his large navy.{{citation needed|date=January 2018}}

The character of the country, intersected by numerous canals and full of strongly fortified towns, was in his favour and Nectanebo II might have been expected to offer a prolonged, if not even a successful resistance. However, he lacked good generals, and, over-confident in his own powers of command, he was out-maneuvered by the Greek mercenary generals, and his forces were eventually defeated by the combined Persian armies. After his defeat, Nectanebo hastily fled to Memphis, leaving the fortified towns to be defended by their garrisons. These garrisons consisted of partly Greek and partly Egyptian troops; between whom jealousies and suspicions were easily sown by the Persian leaders. As a result, the Persians were able to rapidly reduce numerous towns across Lower Egypt and were advancing upon Memphis when Nectanebo decided to quit the country and flee southwards to Ethiopia.<ref name="Persianempire"/> The Persian army completely routed the Egyptians and occupied the Lower Delta of the Nile. Following Nectanebo fleeing to Ethiopia, all of Egypt submitted to Artaxerxes. The Jews in Egypt were sent either to Babylon or to the south coast of the Caspian Sea, the same location that the Jews of Phoenicia had earlier been sent.{{citation needed|date=January 2018}}

After this victory over the Egyptians, Artaxerxes had the city walls destroyed, started a reign of terror, and set about looting all the temples. Persia gained a significant amount of wealth from this looting. Artaxerxes also raised high taxes and attempted to weaken Egypt enough that it could never revolt against Persia. For the 10&nbsp;years that Persia controlled Egypt, believers in the native religion were persecuted and sacred books were stolen.<ref name="Egyptloot">{{cite web|url=http://www.mnsu.edu/emuseum/prehistory/egypt/history/periods/persianii.html |title=Persian Period II |access-date=6 March 2008 |archive-url=https://web.archive.org/web/20080217023749/http://www.mnsu.edu/emuseum/prehistory/egypt/history/periods/persianii.html |archive-date=17 February 2008 |url-status=dead }}</ref> Before Artaxerxes returned to Persia, he appointed Pherendares as satrap of Egypt. With the wealth gained from his reconquering Egypt, Artaxerxes was able to amply reward his mercenaries. He then returned to his capital having successfully completed his invasion of Egypt.{{citation needed|date=January 2018}}

After his success in Egypt, Artaxerxes returned to Persia and spent the next few years effectively quelling insurrections in various parts of the Empire so that a few years after his conquest of Egypt, the Persian Empire was firmly under his control. Egypt remained a part of the Persian Empire from then until Alexander the Great's conquest of Egypt.{{citation needed|date=January 2018}}

After the conquest of Egypt, there were no more revolts or rebellions against Artaxerxes. Mentor and Bagoas, the two generals who had most distinguished themselves in the Egyptian campaign, were advanced to posts of the highest importance. Mentor, who was governor of the entire Asiatic seaboard, was successful in reducing to subjection many of the chiefs who during the recent troubles had rebelled against Persian rule. In the course of a few years, Mentor and his forces were able to bring the whole Asian Mediterranean coast into complete submission and dependence.{{citation needed|date=January 2018}}

Bagoas went back to the Persian capital with Artaxerxes, where he took a leading role in the internal administration of the Empire and maintained tranquillity throughout the rest of the Empire. During the last six years of the reign of Artaxerxes III, the Persian Empire was governed by a vigorous and successful government.<ref name="Persianempire" />

The Persian forces in Ionia and Lycia regained control of the Aegean and the Mediterranean Sea and took over much of Athens' former island empire. In response, Isocrates of Athens started giving speeches calling for a 'crusade against the barbarians' but there was not enough strength left in any of the Greek city-states to answer his call.<ref name="conspiracy">{{cite web|url=http://www.iranologie.com/history/Achaemenid/chapter%20V.html |title=Chapter V: Temporary Relief |access-date=1 March 2008 |url-status=dead |archive-url=https://web.archive.org/web/20080619124220/http://www.iranologie.com/history/Achaemenid/chapter%20V.html |archive-date=19 June 2008 }}</ref>

Although there were no rebellions in the Persian Empire itself, the growing power and territory of Philip II of Macedon in Macedon (against which Demosthenes was in vain warning the Athenians) attracted the attention of Artaxerxes. In response, he ordered that Persian influence was to be used to check and constrain the rising power and influence of the Macedonian kingdom. In 340&nbsp;BC, a Persian force was dispatched to assist the Thracian prince, Cersobleptes, to maintain his independence. Sufficient effective aid was given to the city of Perinthus that the numerous and well-appointed army with which Philip had commenced his siege of the city was compelled to give up the attempt.<ref name="Persianempire"/> By the last year of Artaxerxes' rule, Philip II already had plans in place for an invasion of the Persian Empire, which would crown his career, but the Greeks would not unite with him.<ref>{{cite web |url=http://historyofmacedonia.org/AncientMacedonia/PhilipofMacedon.html |title= Philip of Macedon Philip II of Macedon Biography |access-date=7 March 2008| archive-url= https://web.archive.org/web/20080314165325/http://www.historyofmacedonia.org/AncientMacedonia/PhilipofMacedon.html| archive-date=14 March 2008 | url-status= live}}</ref>

Both the later dynasties of the Parthians and Sasanians would on occasion claim Achaemenid descent.

==Government== thumb|upright=1.6|Satrapies of the Achaemenid Empire showing their ancient names and the extent of their territory. Cyrus the Great founded the empire as a multi-state empire, governed from four capital cities: Pasargadae, Babylon, Susa and Ecbatana. The Achaemenids allowed a certain amount of regional autonomy in the form of the satrapy system. A satrapy was an administrative unit, usually organized on a geographical basis. A 'satrap' (governor) was the governor who administered the region, a 'general' supervised military recruitment and ensured order, and a 'state secretary' kept the official records. The general and the state secretary reported directly to the satrap as well as the central government. At differing times, there were between 20 and 30 satrapies.

Cyrus the Great created an organized army including the Immortals unit, consisting of 10,000 highly trained soldiers{{sfn|Briant|2002|p=261}} Cyrus also formed an innovative postal system throughout the empire, based on several relay stations called Chapar Khaneh.<ref>Herodotus, trans.

Darius also introduced a regulated and sustainable tax system that was precisely tailored to each satrapy, based on their supposed productivity and their economic potential. For instance, Babylon was assessed for the highest amount and for a startling mixture of commodities – 1,000 silver talents, four months' supply of food for the army. India was clearly already fabled for its gold; Egypt was known for the wealth of its crops; it was to be the granary of the Persian Empire (as later of Rome's) and was required to provide 120,000 measures of grain in addition to 700 talents of silver.

=== Transportation and communication === Under the Achaemenids, trade was extensive and there was an efficient infrastructure that facilitated the exchange of commodities in the far reaches of the empire. Tariffs on trade, along with agriculture and tribute, were major sources of revenue for the empire.<ref name="historyworld.net" /><ref>{{cite web|url=http://www.1902encyclopedia.com/D/DAR/darius-i-the-great.html|title=Darius I (Darius the Great), King of Persia (from 521 BC)|publisher=1902encyclopedia.com|access-date=7 January 2011}}</ref> thumb|Letter from the Satrap of Bactria to the governor of Khulmi, concerning camel keepers, 353 BC thumb|Part of the royal road that connected Ecbatana to Anatolia, this road is still in use today.

Another highway of commerce was the Great Khorasan Road, an informal mercantile route that originated in the fertile lowlands of Mesopotamia and snaked through the Zagros highlands, through the Iranian plateau and Afghanistan into the Central Asian regions of Samarkand, Merv and Ferghana, allowing for the construction of frontier cities like Cyropolis. Following Alexander's conquests, this highway allowed for the spread of cultural syncretic fusions like Greco-Buddhism into Central Asia and China, as well as empires like the Kushan, Indo-Greek and Parthian to profit from trade between East and West. This route was greatly rehabilitated and formalized during the Abbasid Caliphate, during which it developed into a major component of the famed Silk Road.<ref>{{Cite web|url=https://en.unesco.org/silkroad/content/diary-young-explorers-iran-and-royal-road|title=The Diary of Young Explorers: Iran and the Royal Road {{!}} Silk Roads|website=en.unesco.org|access-date=2020-04-11}}</ref>

==Military== Despite its humble origins in Persis, the empire reached an enormous size under the leadership of Cyrus the Great. Cyrus created a multi-state empire where he allowed regional rulers, satraps, to rule as his proxy over a certain designated area of his empire called a satrapy.

=== Infantry === The Achaemenid infantry consisted of three groups: the Immortals, the Sparabara, and the Takabara, though in the later years of the Achaemenid Empire, a fourth group, the Cardaces, were introduced.{{citation needed|date=January 2018}}

The Immortals were described by Herodotus as being heavy infantry, led by Hydarnes II, that were kept constantly at a strength of exactly 10,000 men. He claimed that the unit's name stemmed from the custom that every killed, seriously wounded, or sick member was immediately replaced with a new one, maintaining the numbers and cohesion of the unit.<ref name="livius.org2" /> They had wicker shields, short spears, swords or large daggers, and bow and arrows. Underneath their robes they wore scale armour coats. The spear counterbalances of the common soldiery were of silver; to differentiate commanding ranks, the officers' spear butt-spikes were golden.<ref name="livius.org2">{{cite web |last=Jona |first=Lendering |url=https://www.livius.org/articles/concept/immortals/ |title=Immortals|access-date=16 May 2009 |website=Livius.org |date=1997}}</ref> Surviving Achaemenid colored glazed bricks and carved reliefs represent the Immortals as wearing elaborate robes, hoop earrings and gold jewellery, though these garments and accessories were most likely worn only for ceremonial occasions.<ref>Volume IX, Encyclopædia Britannica, Fifteenth Edition 1983</ref>

[[File:Achaemenid infantry on Alexander Sarcophagus.jpg|thumb|upright|Color reconstruction of Achaemenid infantry on the Alexander Sarcophagus (end of 4th century BC).]] The Sparabara were usually the first to engage in hand-to-hand combat with the enemy. Although not much is known about them today, it is believed that they were the backbone of the Persian army who formed a shield wall and used their two-metre-long spears to protect more vulnerable troops such as archers from the enemy. The Sparabara were taken from the full members of Persian society, were trained from childhood to be soldiers and when not called out to fight on campaigns in distant lands they practised hunting on the vast plains of Persia. However, when all was quiet and the ''Pax Persica'' held true, the Sparabara returned to normal life farming the land and grazing their herds. Because of this, they lacked true professional quality on the battlefield, yet they were well trained and courageous to the point of holding the line in most situations long enough for a counter-attack. They were armoured with quilted linen and carried large rectangular wicker shields as a form of light maneuverable defence. This, however, left them at a severe disadvantage against heavily armoured opponents such as the hoplite, and their two-metre-long spear was not able to give the Sparabara ample range to plausibly engage a trained phalanx. The wicker shields were able to effectively stop arrows but not strong enough to protect the soldier from spears. However, the Sparabara could deal with most other infantry, including trained units from the East.{{citation needed|date=January 2018}}

The Achaemenids relied heavily on archery. Major contributing nations were the Scythians, Medes, Persians, and the Elamites. The composite bow was used by the Persians and Medes, who adopted it from the Scythians and transmitted it to other nations, including the Greeks.<ref>{{cite book |last1=Potts |first1=D.

=== Cavalry === [[File:The Darius seal. Darius stands in a royal chariot below Ahura Mazda and shoots arrows at a rampant lion. From Thebes, Egypt. 6th-5th century BCE. British Museum (cropped).jpg|thumb|Seal of Darius the Great hunting in a chariot]]

The Persian cavalry was crucial for conquering nations and maintained its importance in the Achaemenid army to the last days of the Achaemenid Empire. The cavalry was separated into four groups. The chariot archers, horse cavalry, the camel cavalry, and the war elephants.{{citation needed|date=January 2018}}

In the later years of the Achaemenid Empire, the chariot archer had become merely a ceremonial part of the Persian army, yet in the early years of the Empire, their use was widespread. The chariot archers were armed with lances, bows, arrows, swords, and scale armour. The horses were also suited with scale armour similar to scale armour of the Sassanian cataphracts. The chariots would contain imperial symbols and decorations.

[[File:Altıkulaç_Sarcophagus_Combat_scene_(detail).jpg|thumb|Armoured cavalry: Achaemenid Dynast of Hellespontine Phrygia attacking a Greek psiloi, Altıkulaç Sarcophagus, early 4th century BC.]] The horses used by the Achaemenids for cavalry were often suited with scale armour, like most cavalry units. The riders often had the same armour as Infantry units, wicker shields, short spears, swords or large daggers, bow and arrow, and scale armour coats. The camel cavalry was different, because the camels and sometimes the riders, were provided little protection against enemies, yet when they were offered protection, they would have lances, swords, bow, arrow, and scale armour. The camel cavalry was first introduced into the Persian army by Cyrus the Great, at the Battle of Thymbra. The elephant was most likely introduced into the Persian army by Darius I after his conquest of the Indus Valley. Elephants may have been used in Greek campaigns by Darius and Xerxes I, but Greek accounts only mention 15 of them being used at the Battle of Gaugamela.{{citation needed|date=January 2018}}

=== Navy === {{main|Achaemenid navy}}

Since its foundation by Cyrus, the Persian empire had been primarily a land empire with a strong army but void of any actual naval forces. By the 5th century BC, this was to change, as the empire came across Greek and Egyptian forces, each with their own maritime traditions and capabilities. Darius I was the first Achaemenid king to invest in a Persian fleet.<ref name=navy>{{cite book| author = Kaveh Farrokh| title = Shadows in the desert: ancient Persia at war| url = https://books.google.com/books?id=wywlvgAACAAJ | year = 2007 | publisher = Bloomsbury | isbn = 978-1-84603-108-3| page = 68}}</ref> Even by then no true "imperial navy" had existed either in Greece or Egypt. Persia would become the first empire, under Darius, to inaugurate and deploy the first regular imperial navy.<ref name=navy/> Despite this achievement, the personnel for the imperial navy would not come from Iran, but were often Phoenicians (mostly from Sidon), Egyptians and Greeks chosen by Darius the Great to operate the empire's combat vessels.<ref name=navy/>

[[File:BeachedShipsMarathon.jpg|thumb|left|Reconstitution of Persian landing ships at the Battle of Marathon.]] At first the ships were built in Sidon by the Phoenicians; the first Achaemenid ships measured about 40 meters in length and 6 meters in width, able to transport up to 300 Persian troops at any one trip. Soon, other states of the empire were constructing their own ships, each incorporating slight local preferences. The ships eventually found their way to the Persian Gulf<ref name=navy/> and Persian naval forces laid the foundation for a strong Persian maritime presence there. Persians also had ships often of a capacity 100 to 200 troops patrolling the empire's various rivers including the Karun, Tigris and Nile in the west, as well as the Indus.<ref name=navy/>

[[File:Ship dashed against ship, till the Persian Army dead strewed the deep like flowers.jpg|thumb|upright|Greek ships against Achaemenid ships at the Battle of Salamis.]] The Achaemenid navy established bases located along the Karun, and in Bahrain, Oman, and Yemen. The Persian fleet was not only used for peace-keeping purposes along the Karun but also opened the door to trade with India via the Persian Gulf.<ref name=navy/> Darius's navy was in many ways a world power at the time, but it would be Artaxerxes II who in the summer of 397 BC would build a formidable navy, as part of a rearmament which would lead to his decisive victory at Knidos in 394 BC, re-establishing Achaemenid power in Ionia. Artaxerxes II would also use his navy to later on quell a rebellion in Egypt.<ref name=navi>{{cite book| author = Elspeth R.M.

The construction material of choice was wood, but some armoured Achaemenid ships had metallic blades on the front, often meant to slice enemy ships using the ship's momentum. Naval ships were also equipped with hooks on the side to grab enemy ships, or to negotiate their position. The ships were propelled by sails or manpower. The ships the Persians created were unique. As far as maritime engagement, the ships were equipped with two mangonels that would launch projectiles such as stones, or flammable substances.<ref name=navy/>

Xenophon describes his eyewitness account of a massive military bridge created by joining 37 Persian ships across the Tigris. The Persians used each boat's buoyancy to support a connected bridge above which supply could be transferred.<ref name=navy/> Herodotus also gives many accounts of the Persians using ships to build bridges.<ref>{{cite book|title=Encyclopaedia Iranica, Volume 4, Issues 5–8|publisher=Routledge & Kegan Paul|year=1982|author=Ehsan Yar-Shater|author-link=Ehsan Yarshater|title-link=Encyclopaedia Iranica}}</ref><ref>{{cite book|title=The Persian Empire|author=John Manuel Cook|publisher=Schocken Books|year=1983|url=https://archive.org/details/persianempire0000cook/mode/2up|page=109|isbn=978-0-8052-3846-4 |quote=The Achaemenids maintained some bridges on their main routes.

Darius I, in an attempt to subdue the Scythian horsemen north of the Black Sea, crossed over at the Bosphorus, using an enormous bridge made by connecting Achaemenid boats, then marched up to the Danube, crossing it by means of a second boat bridge.<ref>{{cite book|author1=E.V.

Years later, a similar boat bridge would be constructed by Xerxes I, in his invasion of Greece. Although the Persians failed to capture the Greek city-states completely, the tradition of maritime involvement was carried down by the Persian kings, most notably Artaxerxes II. Years later, when Alexander invaded Persia and during his advancement into India, he took a page from the Persian art of war, by having Hephaestion and Perdiccas construct a similar boat-bridge at the Indus river in India in the spring of 327 BC.<ref>{{cite book| author = Waldemar Heckel| title = Who's who in the age of Alexander the Great: prosopography of Alexander's empire| url = https://books.google.com/books?id=JJ4K1wFZkrsC| year = 2006| publisher = Wiley-Blackwell| isbn = 978-1-4051-1210-9| page = 134}}</ref>

During the reign of Cyrus II and Darius I, and as long as the seat of government was still at Susa in Elam, the language of the chancellery was Elamite.

The use of Elamite is not attested after 458 BC.{{citation needed|date=January 2026}}

Following the conquest of Mesopotamia, the Aramaic language (as used in that territory) was adopted as a "vehicle for written communication between the different regions of the vast empire with its different peoples and languages. The use of a single official language, which modern scholarship has dubbed "Official Aramaic" or "Imperial Aramaic", can be assumed to have greatly contributed to the astonishing success of the Achaemenids in holding their far-flung empire together for as long as they did."<ref>{{Encyclopædia Iranica Online|volume=2|fascicle=3|title=Aramaic|last1=Greenfield|first1=Jonas C.|last2=Rosenthal|first2=Franz|last3=Shaked|first3=Shaul|pages=250–261|url=https://www.iranicaonline.org/articles/aramaic/}}</ref>

In 1955, Richard Frye questioned the classification of Imperial Aramaic as an official language, noting that no surviving edict expressly and unambiguously accorded that status to any particular language.<ref>{{cite journal|last1=Frye|first1=Richard N.|author-link1=Richard N.

===Customs=== [[File:Persia - Achaemenian Vessels.jpg|thumb|An Achaemenid rhyton, or drinking vessel]] Herodotus mentions that the Persians were invited to great birthday feasts (Herodotus, ''Histories'' 8), which would be followed by many desserts, a treat which they reproached the Greeks for omitting from their meals. He also observed that the Persians drank wine in large quantities and used it even for counsel, deliberating on important affairs when drunk, and deciding the next day, when sober, whether to act on the decision or set it aside.<ref>{{Cite web|title=Herodotus, The Histories, Book 1, chapter 133|url=https://www.perseus.tufts.edu/hopper/text?doc=Perseus:text:1999.01.0126:book=1:chapter=133|access-date=2020-11-21|website=Perseus }}</ref>

It was during the Achaemenid period that Zoroastrianism reached southwestern 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 Iranian pantheon but also introduced several novel ideas, including that of free will.<ref>{{cite book| author = A.

[[File:201312 iran Shiraz 72 (12475982935).jpg|thumb|A bas-relief of Farvahar at Persepolis]] During the reign of Artaxerxes I and Darius II, the Greek historian Herodotus wrote: "[the Persians] have no images of the gods, no temples nor altars, and consider the use of them a sign of folly. This comes, I think, from their not believing the gods to have the same nature with men, as the Greeks imagine."<ref name="Herodotus, I.131">Herodotus, I.131</ref> He claims the Persians offer sacrifice to: "the sun and moon, to the earth, to fire, to water, and to the winds. These are the only gods whose worship has come down to them from ancient times. At a later period, they began the worship of Urania, which they borrowed from the Arabians and Assyrians. Mylitta is the name by which the Assyrians know this goddess, to whom the Persians referred as Anahita."<ref name="Herodotus, I.131"/>

The Babylonian scholar and priest Berosus records—although writing over seventy years after the reign of Artaxerxes II—that the emperor had been the first to make cult statues of divinities and have them placed in temples in many of the major cities of the empire.<ref>Berosus, III.65</ref> Berosus also substantiates Herodotus when he says the Persians knew of no images of gods until Artaxerxes II erected those images. On the means of sacrifice, Herodotus adds "they raise no altar, light no fire, pour no libations."<ref name="Herodotus, I.132">Herodotus, I.132</ref> Herodotus also observed that "no prayer or offering can be made without a magus present".<ref name="Herodotus, I.132"/>

===Women=== The position of women in the Achaemenid Empire varied depending on the culture to which they belonged and therefore differed by region. The position of Persian women in actual Persia has traditionally been described from mythological Biblical references and the sometimes biased Ancient Greek sources, neither of them fully reliable as sources, but the most reliable references are the archeological Persepolis Fortification Tablets (PFT), which describes women in connection to the royal court in Persepolis, from royal women to female laborers who were recipients of food rations at Persepolis.<ref name="Maria Brosius">{{Encyclopædia Iranica Online|title=Women i. In Pre-Islamic Persia|last=Brosius|first=Maria|url=https://www.iranicaonline.org/articles/women-i/}}</ref>

The hierarchy of royal women at the Persian court was ranked as follows: the king's mother, then the queen, the king's daughters, the king's concubines, and the other women of the royal palace.<ref name="Maria Brosius"/> The king normally married a female member of the royal family or a Persian noblewoman related to a satrap or another important Persian man; it was permitted for members of the royal family to marry relatives, but there is no evidence for marriage between closer family members than half-siblings.<ref name="Maria Brosius"/> The king's concubines were often either slaves, sometimes prisoners of war, or foreign princesses, whom the king did not marry because they were foreigners, and whose children did not have the right to inherit the throne.<ref name="Maria Brosius"/>

Greek sources accuse the king of having hundreds of concubines secluded in a harem. There is no archeological evidence supporting the existence of a harem, or the seclusion of women from contact with men, at the Persian court.<ref name="Maria Brosius"/> The royal women joined the king at breakfast and dinner and accompanied him on his journeys.<ref name="Maria Brosius"/> They may have participated in the royal hunt, as well as during the royal banquets. Herodotus relates how the Persian envoys at the Macedonian court demanded the presence of women during a banquet because it was the custom for women to participate in the banquets in their own country.<ref name="Maria Brosius"/>

The queen may have attended the king's audience, and archeological evidence shows that she gave her own audiences, at least for female supplicants.<ref name="Maria Brosius"/> Royal women and noblewomen at court could travel on their own, accompanied by both male and female staff, own and manage their own fortune, land, and business.<ref name="Maria Brosius"/> Depictions of Persian women show them with long dresses and veils which did not cover their faces or their hair, only flowing down over their neck at the back of the head as an ornament.<ref name="Maria Brosius"/>

Royal and aristocratic Achaemenid women were given an education in subjects that did not appear compatible with seclusions, such as horsemanship and archery.<ref>(Ctesias, frg. 16 (56) in Jacoby, Fragmente III/C, p. 471)</ref> Royal and aristocratic women held and managed vast estates and workshops and employed large numbers of servants and professional laborers.{{sfn|Brosius|1996|pp=125–182}} Royal and aristocratic women do not seem to have lived in seclusion from men, since it is known that they appeared in public{{sfn|Brosius|1996|pp=83–93}} and traveled with their husbands,{{sfn|Brosius|1996|pp=83–93}} participated in hunting<ref>(Heracleides of Cyme apud Athenaeus, 514b)</ref> and in feasts.{{sfn|Brosius|1996|pp=94–97}} The chief wife of a royal or aristocratic man did not live in seclusion, as it is clearly stated that wives customarily accompanied their husbands at dinner banquets. They left the banquet when the "women entertainers" came in and the men began "merrymaking".<ref>(Plutarch, Moralia, 140B)</ref>

No woman ever ruled the Achaemenid Empire, as monarch or as regent, but some queen's consorts are known to have had influence over the affairs of state, notably Atossa and Parysatis.

There is not evidence of any women being employed as an official in the administration or within religious service; however, there are plenty of archeological evidence of women being employed as free labourers in Persepolis, where they worked alongside men.<ref name="Maria Brosius"/> Women could be employed as the leaders of their workforce, known by the title ''arraššara pašabena'', which were then given a higher salary than the male workers of their workforce.<ref name="Maria Brosius"/> Female laborers were given less than men. Qualified workers within the crafts were given equal pay regardless of their sex.<ref name="Maria Brosius"/> Women are abundant in religious context in the cuneiform sources from late Achaemenid and Hellenistic Babylon.<ref>{{cite book |last1=Debourse |first1=Céline |chapter=Women in Cultic Functions in Late Achaemenid and Hellenistic Babylon |pages=147–158 |chapter-url={{GBurl|8bJfEQAAQBAJ|p=147}} |editor1-last=Dolansky |editor1-first=Shawna |editor2-last=Shectman |editor2-first=Sarah |title=The Bloomsbury Handbook of Religion, Gender, and Sexuality in the Ancient Near East |date=2025 |publisher=Bloomsbury Publishing |isbn=978-1-350-38202-2 }}</ref>

===Architecture and art=== {{Main|Achaemenid architecture}}

thumb|The ruins of Persepolis Achaemenid architecture included large cities, temples, palaces, and mausolea such as the Tomb of Cyrus the Great. The quintessential feature of its architecture was its eclectic nature, with elements of Median, Assyrian, and Asiatic Greek all incorporated, yet maintaining a unique Persian identity seen in the finished products.<ref>{{cite book| author = Charles Henry Caffin| title = How to study architecture| url = https://archive.org/details/bub_gb_HnoWAAAAYAAJ| year = 1917| publisher = Dodd, Mead and Company| page = [https://archive.org/details/bub_gb_HnoWAAAAYAAJ/page/n348 80]}}</ref> Its influence pervades the regions ruled by the Achaemenids, from the Mediterranean shores to India, especially with its emphasis on monumental stone-cut design and gardens subdivided by water-courses.<ref>{{Cite web|url=http://theconversation.com/irans-cultural-heritage-reflects-the-grandeur-and-beauty-of-the-golden-age-of-the-persian-empire-129413|title=Iran's cultural heritage reflects the grandeur and beauty of the golden age of the Persian empire|last=MacDonald|first=Eve|website=The Conversation|date=8 January 2020 |language=en|access-date=2020-02-15}}</ref>

Achaemenid art includes frieze reliefs, metalwork such as the Oxus Treasure, decoration of palaces, glazed brick masonry, fine craftsmanship (masonry, carpentry, etc.), and gardening. Although the Persians drew artists from all corners of their empire, incorporating their styles and techniques, they did not merely produce a combination of styles, but a synthesis of a new, unique Persian style.<ref>{{cite book |last1=van Lerberghe |first1=Karel |title=Immigration and Emigration Within the Ancient Near East: Festschrift E.

One of the most remarkable examples of both Achaemenid architecture and art is the grand palace of Persepolis, and its detailed workmanship, coupled with its grand scale. In describing the construction of the Palace of Darius in Susa, Darius the Great records: {{blockquote|text=Yaka timber was brought from Gandara and from Carmania. The gold was brought from Sardis and from Bactria&nbsp;... the precious stone lapis-lazuli and carnelian&nbsp;... was brought from Sogdiana.

The stone-cutters who wrought the stone were Ionians and Sardians. The goldsmiths were Medes and Egyptians. The men who wrought the wood were Sardinians and Egyptians. The men who wrought the baked brick were Babylonians.

=== Tombs === [[File:Iran, Persepolis, Tomb of Artaxerxes III.jpg|thumb|The tomb of Artaxerxes III in Persepolis]] Many Achaemenid rulers built tombs for themselves. The most famous, Naqsh-e Rostam, is an ancient necropolis located about 12&nbsp;km north-west of Persepolis, with the tombs of four of the kings of the dynasty are carved in this mountain: Darius I, Xerxes I, Artaxerxes I and Darius II. Other kings constructed their own tombs elsewhere.<ref name="Viking">{{cite book |last1=Cotterell |first1=Arthur |title=The Penguin Encyclopedia of Classical Civilizations |date=1993 |publisher=Viking |isbn=978-0-670-82699-5 |page=162 }}</ref>

Artaxerxes II and Artaxerxes III preferred to carve their tombs beside their spring capital Persepolis. The left tomb belongs to Artaxerxes II and the right tomb belongs to Artaxerxes III, the last Achaemenid king to have a tomb. The tomb of the founder of the Achaemenid dynasty, Cyrus the Great, was built in Pasargadae (now a world heritage site).<ref name="Viking"/>

==Legacy== [[File:The maussolleion model dsc02711-miniaturk nevit.jpg|thumb|The Mausoleum at Halicarnassus, one of the Seven wonders of the ancient world, was built by Greek architects for the local Persian satrap of Caria, Mausolus (Scale model)]]

The Achaemenid Empire has been referred to as the first “world empire” as it contained in the words of Persian kings “many people and many languages”. The diverse groups which made up the empire enjoyed a great deal of legal and cultural autonomy.<ref>{{Cite book |last=Daryaee |first=Touraj |title=The Oxford Handbook of Iranian History |publisher=Oxford University Press |year=2014 |isbn=978-0199390427 |pages=120}}</ref> The Achaemenid Empire has also left a lasting impression on the heritage and cultural identity of Asia and the Middle East, and influenced the development and structure of future empires. In fact, the Greeks, and later on the Romans, adopted the best features of the Persian method of governing an empire.<ref>"Mastering World History" by Philip L. Groisser, New York, 1970, p.&nbsp;17</ref>

The Persian model of governance was particularly formative in the expansion and maintenance of the Abbasid Caliphate, whose rule is widely considered the period of the Islamic Golden Age. Like the ancient Persians, the Abbasid dynasty centered their vast empire in Mesopotamia (at the newly founded cities of Baghdad and Samarra, close to the historical site of Babylon), derived much of their support from Persian aristocracy and heavily incorporated the Persian language and architecture into Islamic culture.<ref name="Hovannisian">{{Cite book|last1=Hovannisian|first1=Richard G.|url=https://books.google.com/books?id=39XZDnOWUXsC&q=abbasid+and+achaemenid&pg=PA81|title=The Persian Presence in the Islamic World|last2=Sabagh|first2=Georges|last3=Yāršātir|first3=Iḥsān|date=1998|publisher=Cambridge University Press|isbn=978-0-521-59185-0|language=en}}</ref>

The Achaemenid Empire is noted in Western history as the antagonist of the Greek city-states during the Greco-Persian Wars and for the emancipation of the Jewish exiles in Babylon. The historical mark of the empire went far beyond its territorial and military influences and included cultural, social, technological and religious influences as well. For example, many Athenians adopted Achaemenid customs in their daily lives in a reciprocal cultural exchange,<ref>{{cite book| author = Margaret Christina Miller| title = Athens and Persia in the Fifth Century BC: A Study in Cultural Receptivity| url = https://books.google.com/books?id=oGXMMD5rXBQC| year = 2004| publisher = Cambridge University Press| isbn = 978-0-521-60758-2| page = 243}}</ref> some being employed by or allied to the Persian kings. The impact of the Edict of Cyrus is mentioned in Judeo-Christian texts, and the empire was instrumental in the spread of Zoroastrianism as far east as China. The empire also set the tone for the politics, heritage and history of Iran (also known as Persia).<ref>{{cite book|title=Birth of the Persian Empire|author1=Vesta Sarkhosh Curtis |author2=Sarah Stewart |publisher=I.B.Tauris|year=2005|page=7|url=https://books.google.com/books?id=a0IF9IdkdYEC&pg=PA7|isbn=978-1-84511-062-8}}</ref>

Historian Arnold Toynbee regarded Abbasid society as a "reintegration" or "reincarnation" of Achaemenid society, as the synthesis of Persian, Turkic and Islamic modes of governance and knowledge allowed for the spread of Persianate culture over a wide swath of Eurasia through the Turkic-origin Seljuq, Ottoman, Safavid and Mughal empires.<ref name="Hovannisian" /> Historian Bernard Lewis writes,

<blockquote>The work of Iranians can be seen in every field of cultural endeavor, including Arabic poetry, to which poets of Iranian origin composing their poems in Arabic made a very significant contribution. In a sense, Iranian Islam is a second advent of Islam itself, a new Islam sometimes referred to as Islam-i-Ajam. It was this Persian Islam, rather than the original Arab Islam, that was brought to new areas and new peoples: to the Turks, first in Central Asia and then in the Middle East in the country which came to be called Turkey, and of course to India. The Ottoman Turks brought a form of Iranian civilization to the walls of Vienna. [...] By the time of the great Mongol invasions of the thirteenth century, Iranian Islam had become not only an important component; it had become a dominant element in Islam itself, and for several centuries the main centers of the Islamic power and civilization were in countries that were, if not Iranian, at least marked by Iranian civilization ... The major centers of Islam in the late medieval and early modern periods, the centers of both political and cultural power, such as India, Central Asia, Iran, Turkey, were all part of this Iranian civilization.<ref>{{cite book |title=From Babel to Dragomans: Interpreting the Middle East |url=https://archive.org/details/frombabeltodrago00lewi |url-access=registration |first=Bernard |last=Lewis |publisher=Oxford University Press |year=2004 |page=[https://archive.org/details/frombabeltodrago00lewi/page/44 44] |isbn=978-0-19-517336-9}}</ref></blockquote>

Georg W. F. Hegel in his work ''The Philosophy of History'' introduces the Persian Empire as the "first empire that passed away" and its people as the "first historical people" in history. According to his account:

<blockquote>The Persian Empire is an empire in the modern sense—like that which existed in Germany, and the great imperial realm under the sway of Napoleon; for we find it consisting of a number of states, which are indeed dependent, but which have retained their own individuality, their manners, and laws. The general enactments, binding upon all, did not infringe upon their political and social idiosyncrasies, but even protected and maintained them; so that each of the nations that constitute the whole, had its own form of constitution. As light illuminates everything—imparting to each object a peculiar vitality—so the Persian Empire extends over a multitude of nations, and leaves to each one its particular character. Some have even kings of their own; each one its distinct language, arms, way of life and customs. All this diversity coexists harmoniously under the impartial dominion of Light&nbsp;... a combination of peoples—leaving each of them free. Thereby, a stop is put to that barbarism and ferocity with which the nations had been wont to carry on their destructive feuds.<ref>{{cite book|title=The Philosophy of History |author=George W.F. Hegel |url=https://books.google.com/books?id=GbxWvCCUdD8C |isbn=978-1-60206-438-6|year=2007|publisher=Cosimo }}</ref></blockquote>

Will Durant, the American historian and philosopher, during one of his speeches, "Persia in the History of Civilization", as an address before the ''Iran–America Society'' in Tehran on 21 April 1948, stated:

<blockquote>For thousands of years Persians have been creating beauty. Sixteen centuries before Christ there went from these regions or near it&nbsp;... You have been here a kind of watershed of civilization, pouring your blood and thought and art and religion eastward and westward into the world&nbsp;... I need not rehearse for you again the achievements of your Achaemenid period. Then for the first time in known history an empire almost as extensive as the United States received an orderly government, a competence of administration, a web of swift communications, a security of movement by men and goods on majestic roads, equalled before our time only by the zenith of Imperial Rome.<ref>{{cite web|last=Durant|first=Will|title=Persia in the History of Civilization|url=http://www.mazdapublisher.com/Documents/Persian%20Civilization.pdf|website=Addressing 'Iran-America Society|publisher=Mazda Publishers, Inc.|url-status=usurped|archive-url=https://web.archive.org/web/20110723072146/http://www.mazdapublisher.com/Documents/Persian%20Civilization.pdf|archive-date=23 July 2011}}</ref></blockquote>
