The Achaemenid Empire (/əˈkiːmənɪd/, Old Persian Haxāmanišiya, c. 550–330 BC), also called the First Persian Empire, was an empire based in Western Asia, founded by Cyrus the Great, notable for including various civilizations and becoming the largest empire of ancient history, spanning at its maximum extent from the Balkans and Eastern Europe proper in the west, to the Indus Valley in the east. It is equally notable for its successful model of a centralised, bureaucratic administration (through satraps under the King of Kings), for building infrastructure such as a postal system and road systems and the use of an official language across its territories and a large professional army and civil services (inspiring similar systems in later empires). It 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 Mausoleum at Halicarnassus, one of the Seven Wonders of the Ancient World, was built in the empire as well.

By the 7th century BC, the Persians had settled in the southwestern portion of the Iranian Plateau in the region of Persis, which came to be their heartland. From this region, Cyrus the Great advanced to defeat the Medes, Lydia, and the Neo-Babylonian Empire, and established the Achaemenid Empire, which, at its greatest extent included all of the territory of modern-day Iran, Turkey, Iraq, Kuwait, Syria, Jordan, Israel, Palestine, Lebanon, Afghanistan, all significant population centers of Ancient Egypt as far west as eastern Libya, Thrace-Macedonia and Paeonia, the Black Sea coastal regions of Bulgaria, Romania, Ukraine, and Russia, all of Armenia, Georgia (incl. Abkhazia), Azerbaijan, parts of the North Caucasus, and much of Central Asia; encompassing around 5.5 million square kilometers, making it one of the largest empires in history. With some population estimates of 50 million in 480 BC, the Achaemenid Empire at its peak was one of the empires with the highest share of the global population.

The delegation of power to local governments is thought to have eventually weakened the king's authority, causing resources to be expended in attempts to subdue local rebellions, and leading to the disunity of the region at the time of Alexander the Great's invasion in 334 BC. This viewpoint, however, is challenged by some modern scholars who argue that the Achaemenid Empire was not facing any such crisis around the time of Alexander, and that only internal succession struggles within the Achaemenid family ever came close to weakening the empire. Alexander, an avid admirer of Cyrus the Great, would eventually conquer the empire in its entirety by 330 BC. Upon his death most of the empire's former territory came under the rule of the Ptolemaic Kingdom and Seleucid Empire, in addition to other minor territories which gained independence at that time. The Persian population of the central plateau would eventually reclaim power by the second century BC under the Parthian Empire.

The historical mark of the Achaemenid Empire went far beyond its territorial and military influences and included cultural, social, technological and religious influences as well. Many Athenians adopted Achaemenid customs in their daily lives in a reciprocal cultural exchange, some being employed by, or allied to the Persian kings. The impact of Cyrus's edict is mentioned in Judeo-Christian texts and the empire was instrumental in the spread of Zoroastrianism as far east as China. The Empire would also set the tone for the politics, heritage and history of modern Iran.

The Persian nation contains a number of tribes as listed here. ... : the Pasargadae, Maraphii, and Maspii, upon which all the other tribes are dependent. Of these, the Pasargadae are the most distinguished; they contain the clan of the Achaemenids from which spring the Perseid kings. Other tribes are the Panthialaei, Derusiaei, Germanii, all of which are attached to the soil, the remainder -the Dai, Mardi, Dropici, Sagarti, being nomadic.

The Achaemenid Empire was created by nomadic Persians. The name "Persia" is a Greek and Latin pronunciation of the native word referring to people originating from Persis (or in Persian, Pars), their home territory located north of the Persian Gulf in southwestern Iran.

Despite its success and rapid expansion, the Achaemenid Empire was not the first Iranian empire, as by 6th century BC another group of ancient Iranian peoples had already established the Median Empire. The Medes had originally been the dominant Iranian group in the region, rising to power at the end of the seventh century BC and incorporating the Persians into their empire. The Iranian people had arrived in the region c. 1000 BC and had initially fallen under the domination of the Neo-Assyrian Empire (911–609 BC). However, the Medes and Persians (together with the Scythians and Babylonians) played a major role in the defeat of the Assyrians and establishment of the first Persian empire.

The term Achaemenid is in fact the Latinized version of the Old Persian name Haxāmaniš (a bahuvrihi compound translating to "having a friend's mind"), meaning in Greek "of the family of the Achaemenis." Despite the derivation of the name, Achaemenes was himself a minor seventh-century ruler of the Anshan (Ansham or Anšān) in southwestern Iran. It was not until the time of Cyrus the Great (Cyrus II of Persia), a descendant of Achaemenes, that the Achaemenid Empire developed the prestige of an empire and set out to incorporate the existing empires of the ancient east, becoming the vast Persian Empire of ancient legend.

At some point in 550 BC, Cyrus rose in rebellion against the Medes (most likely due to their mismanagement of Persis), eventually conquering the Medes and creating the first Persian empire. Cyrus the Great utilized his tactical genius, as well as his understanding of the socio-political conditions governing his territories, to eventually incorporate into the Empire neighbouring Lydia and the Neo-Babylonian Empire, also leading the way for his successor, Cambyses II, to venture into Egypt and defeat the Twenty-sixth Dynasty of Egypt.

Cyrus the Great's political acumen was reflected in his management of his newly formed empire, as the Persian Empire became the first to attempt to govern many different ethnic groups on the principle of equal responsibilities and rights for all people, so long as subjects paid their taxes and kept the peace. Additionally, the king agreed not to interfere with the local customs, religions, and trades of its subject states, a unique quality that eventually won Cyrus the support of the Babylonians. This system of management ultimately became an issue for the Persians, as with a larger empire came the need for order and control, leading to expenditure of resources and mobilization of troops to quell local rebellions, and weakening the central power of the king. By the time of Darius III, this disorganization had almost led to a disunited realm.

The Persians from whom Cyrus hailed were originally nomadic pastoralists in the western Iranian Plateau and by 850 BC were calling themselves the Parsa and their constantly shifting territory Parsua, for the most part localized around Persis. As Persians gained power, they developed the infrastructure to support their growing influence, including creation of a capital named Pasargadae and an opulent city named Persepolis.

Begun during the rule of Darius I "the Great" and completed some 100 years later, Persepolis was a symbol of the empire serving both as a ceremonial centre and a center of government. It had a special set of gradually progressive stairways named "All Countries" around which carved relief decoration depicted scenes of heroism, hunting, natural themes, and presentation of the gifts to the Achaemenid kings by their subjects during the spring festival, Nowruz. The core structure was composed of a multitude of square rooms or halls, the biggest of which was called Apadana. Tall, decorated columns welcomed visitors and emphasized the height of the structure. Later on, Darius also utilized Susa and Ecbatana as his governmental centres, developing them to a similar metropolitan status.

Accounts of the Achaemenid family tree can be derived from either documented Greek or Roman accounts, or from existing documented Persian accounts such as those found in the Behistun Inscription. However, since most existing accounts of this vast empire are in works of Greek philosophers and historians, and since many of the original Persian documents are lost, not to mention being subject to varying scholarly views on their origin and possible motivations behind them, it is difficult to create a definitive and completely objective list. Nonetheless, it is clear that Cyrus and Darius were critical in the expansion of the empire. Cyrus is often believed to be the son of Cambyses I, grandson of Cyrus I, the father of Cambyses II, and a relative of Darius through a shared ancestor, Teispes. Cyrus the Great is also believed to have been a family member (possibly grandson) of the Median king Astyages through his mother, Mandane of Media. A minority of scholars argue that perhaps Achaemenes was a retrograde creation of Darius in order to reconcile his connection with Cyrus after gaining power.

Ancient Greek writers provide some legendary information about Achaemenes by calling his tribe the Pasargadae and stating that he was "raised by an eagle". Plato, when writing about the Persians, identified Achaemenes with Perses, ancestor of the Persians in Greek mythology. According to Plato, Achaemenes was the same person as Perses, a son of the Ethiopian queen Andromeda and the Greek hero Perseus, and a grandson of Zeus. Later writers believed that Achaemenes and Perseus were different people, and that Perses was an ancestor of the king. This account further confirms that Achaemenes could well have been a significant Anshan leader and an ancestor of Cyrus the Great. Regardless, both Cyrus the Great and Darius the Great were related, prominent kings of Persia, under whose rule the empire expanded to include much of the ancient world.

The empire took its unified form with a central administration around Pasargadae erected by Cyrus the Great. The empire ended up conquering and enlarging the Median Empire to include in addition many more territories, for example in Europe, the Caucasus, Asia Minor, Egypt, and Central Asia. During the reigns of Darius I and his son Xerxes I it engaged in military conflict with some of the major city-states of Ancient Greece, and although it came close to defeating the Greek army, this war ultimately led to the empire's overthrow.

In 559 BC, Cambyses I the Elder was succeeded as the king of Anšān by his son Cyrus the Great, who also succeeded the still-living Arsames as the King of Persia, thus reuniting the two realms. Cyrus is considered to be the first true king of the Persian Empire, as his predecessors were subservient to the Medes. Cyrus the Great conquered Media, Lydia, and Babylon. Cyrus was politically shrewd, modeling himself as the "savior" of conquered nations, often allowing displaced people to return, and giving his subjects freedom to practice local customs. To reinforce this image, he instituted policies of religious freedom, and restored temples and other infrastructure in the newly acquired cities (Most notably the Jewish inhabitants of Babylon, as recorded in the Cyrus Cylinder and the Tanakh). As a result of his tolerant policies he came to be known by those of the Jewish faith as "the anointed of the Lord."

His immediate successors were less successful. Cyrus' son Cambyses II conquered Egypt in 525 BC, but died in July 522 BC during a revolt led by a sacerdotal clan that had lost its power following Cyrus' conquest of Media. The cause of his death remains uncertain, although it may have been the result of an accident.

According to Herodotus, Cambyses II had originally ventured into Egypt to take revenge for the pharaoh Amasis's trickery when he sent a fake Egyptian bride whose family Amasis had murdered, instead of his own daughter, to wed Cambyses II. Additionally negative reports of mistreatment caused by Amasis, given by Phanes of Halicarnassus, a wise counsellor serving Amasis, further bolstered Cambyses's resolve to venture into Egypt. Amasis died before Cambyses II could face him, but his successor Psamtik III was defeated by Cambyses II in the Battle of Pelusium.

While Cambyses II was in Egypt, the Zoroastrian priests, whom Herodotus called Magi, usurped the throne for one of their own, Gaumata, who then pretended to be Cambyses II's younger brother Bardiya (Greek: Smerdis or Tanaoxares/Tanyoxarkes), who had been assassinated some three years earlier. Owing to the strict rule of Cambyses II, especially his stance on taxation, and his long absence in Egypt, "the whole people, Perses, Medes and all the other nations," acknowledged the usurper, especially as he granted a remission of taxes for three years. Cambyses II himself would not be able to quell the imposters, as he died on the way back from Egypt.

The claim that Gaumata had impersonated Bardiya (Smerdis), is derived from Darius the Great and the records at the Behistun Inscription. Historians are divided over the possibility that the story of the impostor was invented by Darius as justification for his coup. Darius made a similar claim when he later captured Babylon, announcing that the Babylonian king was not, in fact, Nebuchadnezzar III, but an impostor named Nidintu-bel.

According to the Behistun Inscription, Gaumata ruled for seven months before being overthrown in 522 BC by Darius the Great (Darius I) (Old Persian Dāryavuš, "who holds firm the good", also known as Darayarahush or Darius the Great). The Magi, though persecuted, continued to exist, and a year following the death of the first pseudo-Smerdis (Gaumata), saw a second pseudo-Smerdis (named Vahyazdāta) attempt a coup. The coup, though initially successful, failed.

Herodotus writes that the native leadership debated the best form of government for the empire. It was agreed that an oligarchy would divide them against one another, and democracy would bring about mob rule resulting in a charismatic leader resuming the monarchy. Therefore, they decided a new monarch was in order, particularly since they were in a position to choose him. Darius I was chosen monarch from among the leaders. He was cousin to Cambyses II and Bardiya (Smerdis), claiming Ariaramnes as his ancestor.

The Achaemenids thereafter consolidated areas firmly under their control. It was Cyrus the Great and Darius the Great who, by sound and farsighted administrative planning, brilliant military maneuvering, and a humanistic world view, established the greatness of the Achaemenids and, in less than thirty years, raised them from an obscure tribe to a world power. It was during the reign of Darius the Great (Darius I) that Persepolis was built (518–516 BC) and which would serve as capital for several generations of Achaemenid kings. Ecbatana (Hagmatāna "City of Gatherings", modern: Hamadan) in Media was greatly expanded during this period and served as the summer capital.

Ever since the Macedonian king Amyntas I surrendered his country to the Persians in about 512-511, Macedonians and Persians were strangers no more as well. Subjugation of Macedonia was part of Persian military operations initiated by Darius the Great (521–486) in 513 - after immense preparations - a huge Achaemenid army invaded the Balkans and tried to defeat the European Scythians roaming to the north of the Danube river. Darius' army subjugated several Thracian peoples, and virtually all other regions that touch the European part of the Black Sea, such as parts of nowadays Bulgaria, Romania, Ukraine, and Russia, before it returned to Asia Minor. Darius left in Europe one of his commanders named Megabazus whose task was to accomplish conquests in the Balkans. The Persian troops subjugated gold-rich Thrace, the coastal Greek cities, as well as defeating and conquering the powerful Paeonians. Finally, Megabazus sent envoys to Amyntas, demanding acceptance of Persian domination, which the Macedonians did. The Balkans provided many soldiers for the multi-ethnic Achaemenid army. Many of the Macedonian and Persian elite intermarried, such as the Persian official Bubares who married Amyntas' daughter, Gygaea. Family ties the Macedonian rulers Amyntas and Alexander enjoyed with Bubares ensured them good relations with the Persian kings Darius and Xerxes I. 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. All in all, the Macedonians were "willing and useful Persian allies. Macedonian soldiers fought against Athens and Sparta in Xerxes' army. The Persians referred to both Greeks and Macedonians as Yauna ("Ionians", their term for "Greeks"), and to Macedonians specifically as Yaunã Takabara or "Greeks with hats that look like shields", possibly referring to the Macedonian kausia hat.

By the 5th century BC the Kings of Persia were either ruling over or had subordinated territories encompassing not just all of the Persian Plateau and all of the territories formerly held by the Assyrian Empire (Mesopotamia, the Levant, Cyprus and Egypt), but beyond this all of Anatolia and Armenia, as well as the Southern Caucasus and parts of the North Caucasus, Azerbaijan, Uzbekistan, Tajikistan, all of Bulgaria, Paeonia, Thrace and Macedonia to the north and west, most of the Black Sea coastal regions, parts of Central Asia as far as the Aral Sea, the Oxus and Jaxartes to the north and north-east, the Hindu Kush and the western Indus basin (corresponding to modern Afghanistan and Pakistan) to the far east, parts of northern Arabia to the south, and parts of northern Libya to the south-west, and parts of Oman, China, and the UAE.

Greco-Persian Wars

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 tyrant, Aristagoras chose to incite the whole of Ionia into rebellion against the Persian king Darius the Great.

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. 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. The first campaign of the invasion was to bring the territories in the Balkan peninsula back within the empire. The Persian grip over these territories had loosened following the Ionian Revolt. In 492 BC, the Persian general Mardonius re-subjugated Thrace and made Macedon a fully subordinate part of the empire; it had been a vassal as early as the late 6th century BC, but retained a great deal of autonomy. However, in 490 BC the Persian forces were defeated by the Athenians at the Battle of Marathon and Darius would die before having the chance to launch an invasion of Greece.

Map showing events of the first phases of the Greco-Persian Wars

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, 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 at 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 strategic victory for the Persians, giving them uncontested control of Artemisium and the Aegean Sea.

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. In 480 BC the Greeks won a decisive victory over the Persian fleet at the Battle of Salamis and forced Xerxes to retire to Sardis. The land army which he left in Greece under Mardonius retook Athens but was eventually destroyed in 479 BC at the Battle of Plataea. The final defeat of the Persians at Mycale encouraged the Greek cities of Asia to revolt, and the Persians lost all of their territories in Europe; Macedonia once again became independent.

Cultural phase

Cyrus the Great king of Iran (ancient Persia) liberated the Hebrew captives in Babylon to resettle and rebuild Jerusalem, earning him an honored place in Judaism.

After Xerxes I was assassinated, he was succeeded by his eldest son Artaxerxes I. It was during his reign that Elamite ceased to be the language of government, 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 state, and for this Artaxerxes I is today also known as the Constantine of that faith.

After Persia had been defeated at Battle of Eurymedon (469 BC), military action between Greece and Persia was halted. When Artaxerxes 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 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 BC.

Artaxerxes I offered asylum to Themistocles, who was the winner of the Battle of Salamis, after Themistocles was ostracized from Athens. Also, Artaxerxes I gave him Magnesia, Myus, and Lampsacus to maintain him in bread, meat, and wine. In addition, Artaxerxes I gave him Palaescepsis to provide him with clothes, and he also gave him Percote with bedding for his house.

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 son Xerxes II, who was the only legitimate son of Artaxerxes. 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. He reigned for six months and fifteen days before being captured by his half-brother, Ochus, who had rebelled against him. Sogdianus was executed by being suffocated in ash because Ochus had promised he would not die by the sword, by poison or by hunger. Ochus then took the royal name Darius II. Darius' ability to defend his position on the throne ended the short power vacuum.

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 hired an army 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.

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. 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 had taken over the concept of a mandatory temple tax, a one-tenth tithe which all inhabitants paid to the temple nearest to their land or other source of income. A share of this income called the Quppu Sha Sharri, "kings chest"—an ingenious institution originally introduced by Nabonidus—was then turned over to the ruler. In retrospect, Artaxerxes is generally regarded as an amiable man who lacked the moral fibre to be a really successful ruler. However, six centuries later Ardeshir I, founder of the second Persian Empire, would consider himself Artaxerxes' successor, a grand testimony to the importance of Artaxerxes to the Persian psyche.

Daric of Artaxerxes II

Artaxerxes II became involved in a war with Persia's erstwhile allies, the Spartans, who, under Agesilaus II, invaded Asia Minor. In order 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 386 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 more than 115 sons from 350 wives.

In 358 BC Artaxerxes II died and was succeeded by his son Artaxerxes III. In 355 BC, Artaxerxes III forced Athens to conclude a peace which required the city's forces to leave Asia Minor and to acknowledge the independence of its rebellious allies. Artaxerxes started a campaign against the rebellious Cadusians, but he managed to appease both of the Cadusian kings. One individual who successfully emerged from this campaign was Darius Codomannus, who later occupied the Persian throne as Darius III.

Artaxerxes III then ordered the disbanding of all the satrapal armies of Asia Minor, as he felt that they could no longer guarantee peace in the west and was concerned that these armies equipped the western satraps with the means to revolt. The order was however ignored by Artabazus of Lydia, who asked for the help of Athens in a rebellion against the king. Athens sent assistance to Sardis. Orontes of Mysia also supported Artabazus and the combined forces managed to defeat the forces sent by Artaxerxes III in 354 BC. However, in 353 BC, they were defeated by Artaxerxes III's army and were disbanded. Orontes was pardoned by the king, while Artabazus fled to the safety of the court of Philip II of Macedon. In around 351 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. Levying a vast army, Artaxerxes marched into Egypt, and engaged Nectanebo II. After a year of fighting the Egyptian Pharaoh, Nectanebo inflicted a crushing defeat on the Persians with the support of mercenaries led by the Greek generals Diophantus and Lamius. Artaxerxes was compelled to retreat and postpone his plans to reconquer Egypt. Soon after this defeat, there were rebellions in Phoenicia, Asia Minor and Cyprus. In 343 BC, Artaxerxes committed responsibility for the suppression of the Cyprian rebels to Idrieus, prince of Caria, who employed 8,000 Greek mercenaries and forty triremes, commanded by Phocion the Athenian, and Evagoras, son of the elder Evagoras, the Cypriot monarch. Idrieus succeeded in reducing Cyprus. Artaxerxes initiated a counter-offensive against Sidon by commanding Belesys, satrap of Syria and Mezseus, 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.

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 afterwards, 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. Forty thousand people died in the conflagration. Artaxerxes sold the ruins at a high price to speculators, who calculated on reimbursing themselves by the treasures which they hoped to dig out from among the ashes. Tennes was later put to death by Artaxerxes. Artaxerxes later sent Jews who supported the revolt to Hyrcania the south coast of the Caspian Sea.

The reduction of Sidon was followed closely by the invasion of Egypt. In 343 BC, Artaxerxes, 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 which he had brought to the aid of Tennes from Egypt; 3,000 sent by Argos; and 1000 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.

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-manoeuvred by the Greek mercenary generals and his forces eventually defeated by the combined Persian armies at the Battle of Pelusium (343 BC). 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. 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.

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 years that Persia controlled Egypt, believers in the native religion were persecuted and sacred books were stolen. Before he 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.

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 until Alexander the Great's conquest of Egypt.

Persian Empire timeline including important events and territorial evolution.

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.

Bagoas went back to the Persian capital with Artaxerxes, where he took a leading role in the internal administration of the Empire and maintained tranquility 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.

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.

Although there weren't any 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 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. 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.

In 338 BC Artaxerxes was poisoned by Bagoas with the assistance of a physician.

Fall of the empire

Artaxerxes III was succeeded by Artaxerxes IV Arses, who before he could act was also poisoned by Bagoas. Bagoas is further said to have killed not only all Arses' children, but many of the other princes of the land. Bagoas then placed Darius III, a nephew of Artaxerxes IV, on the throne. Darius III, previously Satrap of Armenia, personally forced Bagoas to swallow poison. In 334 BC, when Darius was just succeeding in subduing Egypt again, Alexander and his battle-hardened troops invaded Asia Minor.

Alexander the Great (Alexander III of Macedon) defeated the Persian armies at Granicus (334 BC), followed by Issus (333 BC), and lastly at Gaugamela (331 BC). Afterwards, he marched on Susa and Persepolis which surrendered in early 330 BC. From Persepolis, Alexander headed north to Pasargadae where he visited the tomb of Cyrus, the burial of the man whom he had heard of from the Cyropedia.

In the ensuing chaos created by Alexander's invasion of Persia, Cyrus's tomb was broken into and most of its luxuries were looted. When Alexander reached the tomb, he was horrified by the manner in which it had been treated, and questioned the Magi, putting them on trial. By some accounts, Alexander's decision to put the Magi on trial was more an attempt to undermine their influence and display his own power than a show of concern for Cyrus's tomb. Regardless, Alexander the Great ordered Aristobulus to improve the tomb's condition and restore its interior, showing respect for Cyrus. From there he headed to Ecbatana, where Darius III had sought refuge.

Darius III was taken prisoner by Bessus, his Bactrian satrap and kinsman. As Alexander approached, Bessus had his men murder Darius III and then declared himself Darius' successor, as Artaxerxes V, before retreating into Central Asia leaving Darius' body in the road to delay Alexander, who brought it to Persepolis for an honorable funeral. Bessus would then create a coalition of his forces, in order to create an army to defend against Alexander. Before Bessus could fully unite with his confederates at the eastern part of the empire, Alexander, fearing the danger of Bessus gaining control, found him, put him on trial in a Persian court under his control, and ordered his execution in a "cruel and barbarous manner".

Alexander generally kept the original Achaemenid administrative structure, leading some scholars to dub him as "the last of the Achaemenids" Upon Alexander's death in 323 BC, his empire was divided among his generals, the Diadochi, resulting in a number of smaller states. The largest of these, which held sway over the Iranian plateau, was Seleucid Empire, ruled by Alexander's general Seleucus I Nicator. Native Iranian rule would be restored by the Parthians of northeastern Iran over the course of the 2nd century BC.

Descendants in later Iranian dynasties

Istakhr, one of the vassal kingdoms of the Parthian Empire, would be overthrown by Papak, a priest of the temple there. Papak's son, Ardašir I, who named himself in remembrance of Artaxerxes II, would revolt against the Parthians, eventually defeating them and establishing the Sassanid Empire or as it is known the second Persian Empire.

The Achaemenid line would be carried on through the Kingdom of Pontus, based in the Pontus region of northern Asia Minor. This Pontic Kingdom, a state of Persian origin, may even have been directly related to Darius the Great and the Achaemenid dynasty. It was founded by Mithridates I in 281 BC and lasted until its conquest by the Roman Republic in 63 BC. The kingdom grew to its largest extent under Mithridates VI the Great, who conquered Colchis, Cappadocia, Bithynia, the Greek colonies of the Tauric Chersonesos and for a brief time the Roman province of Asia. Thus, this Persian dynasty managed to survive and prosper in the Hellenistic world while the main Persian Empire had fallen.

Both the later dynasties of the Parthians and Sasanians would on occasion claim Achaemenid descent. Recently there has been some corroboration for the Parthian claim to Achaemenid ancestry via the possibility of an inherited disease (neurofibromatosis) demonstrated by the physical descriptions of rulers and from evidence of familial disease on ancient coinage.

Causes of decline

Part of the cause of the Empire's decline had been the heavy tax burden put upon the state, which eventually led to economic decline. An estimate of the tribute imposed on the subject nations was up to U.S. $180M per year. This does not include the material goods and supplies that were supplied as taxes. After the high overhead of government - the military, the bureaucracy, whatever the satraps could safely dip into the coffers for themselves - this money went into the royal treasury. According to Diodorus, at Persepolis, Alexander III found some 180,000 Attic talents of silver besides the additional treasure the Macedonians were carrying that already had been seized in Damascus by Parmenion. This amounted to U.S. $2.7B. On top of this, Darius III had taken 8,000 talents with him on his flight to the north. Alexander put this static hoard back into the economy, and upon his death some 130,000 talents had been spent on the building of cities, dockyards, temples, and the payment of the troops, besides the ordinary government expenses. Additionally, one of the satraps, Harpalus, had made off to Greece with some 6,000 talents, which Athens used to rebuild its economy after seizing it during the struggles with the Corinthian League. Due to the flood of money from Alexander's hoard entering Greece, however, a disruption in the economy occurred, in agriculture, banking, rents, the great increase in mercenary soldiers that cash allowed the wealthy, and an increase in piracy.

Another factor contributing to the decline of the Empire after Xerxes was its failure to ever mold the many subject nations into a whole; the creation of a national identity was never attempted. This lack of cohesion eventually affected the efficiency of the military.

Government

The Behistun Inscription tells the story of Darius the Great's conquests, with the names of twenty-three satrapys subject to him.

Behistun Inscription, column 1 (DB I 1–15)

Cyrus the Great founded the empire as a multi-state empire, governed by four capital states; Pasargadae, Babylon, Susa and Ekbatana. 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 Cyrus also formed an innovative postal system throughout the empire, based on several relay stations called Chapar Khaneh.

Darius the Great reinforced the empire and expanded Persepolis as a ceremonial capital; he revolutionized the economy by placing it on a silver and gold coinage and introducing 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 – 1000 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. This was exclusively a tax levied on subject peoples. Other accomplishments of Darius' reign included codification of the data, a universal legal system, and construction of a new capital at Persepolis.

Under the Achaemenids, the 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 were one of the empire's main sources of revenue, along with agriculture and tribute.

The satrapies were linked by a 2,500-kilometer highway, the most impressive stretch being the Royal Road from Susa to Sardis, built by command of Darius I. The relays of mounted couriers could reach the remotest of areas in fifteen days. Herodotus observes that "there is nothing in the world that travels faster than these Persian couriers. Neither snow, nor rain, nor heat, nor gloom of night stays these courageous couriers from the swift completion of their appointed rounds." Despite the relative local independence afforded by the satrapy system, royal inspectors, the "eyes and ears of the king", toured the empire and reported on local conditions.

The practice of slavery in Achaemenid Persia was generally banned, although there is evidence that conquered and/or rebellious armies were sold into captivity. The kings of Achaemenid Persia, especially the founder Cyrus the Great, occasionally declined to adopt slavery, as evidenced by the freeing of the Jews at Babylon, and the construction of Persepolis by paid workers.

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, called the 'satrap' to rule as his proxy over a certain designated area of his empire called the satrapy. The basic rule of governance was based upon loyalty and obedience of each satrapy to the central power, or the king, and compliance with tax laws. Due to the ethnocultural diversity of the subject nations under the rule of Persia, its enormous geographic size, and the constant struggle for power by regional competitors, the creation of a professional army was necessary for both maintenance of the peace, and also to enforce the authority of the king in cases of rebellion and foreign threat. Cyrus managed to create a strong land army, using it to advance in his campaigns in Babylonia, Lydia, and Asia Minor, which after his death was used by his son Cambyses II, in Egypt against Psamtik III. Cyrus would die battling a local Iranian insurgency in the empire, before he could have a chance to develop a naval force. That task however would fall to Darius the Great, who would officially give Persians their own royal navy to allow them to engage their enemies on multiple seas of this vast empire, from the Black Sea and the Aegean Sea, to the Persian Gulf, Ionian Sea and the Mediterranean Sea.

Military composition

The empire's great armies were, like the empire itself, very diverse, having: Persians, Macedonians, European Thracians, Paeonians, Medes, Achaean Greeks, Cissians, Hyrcanians, Assyrians, Chaldeans, Bactrians, Sacae, Arians, Parthians, Caucasian Albanians, Chorasmians, Sogdians, Gandarians, Dadicae, Caspians, Sarangae, Pactyes, Utians, Mycians, Phoenicians along with the "Syrians of Palestine" (likely Judeans), Egyptians, Cyprians, Cilicians, Pamphylians, Lycians, Dorians of Asia, Carians, Ionians, Aegean islanders, Aeolians, Greeks from Pontus, Paricanians, Arabians, Ethiopians of Africa, Ethiopians of Baluchistan, Libyans, Paphlagonians, Ligyes, Matieni, Mariandyni, Cappadocians, Phrygians, Armenians, Lydians, Mysians, Asian Thracians, Lasonii, Milyae, Moschi, Tibareni, Macrones, Mossynoeci, Mares, Colchians, Alarodians, Saspirians, Red Sea islanders, Sagartians, Indians, Eordi, Bottiaei, Chalcidians, Brygians, Pierians, Perrhaebi, Enienes, Dolopes, and Magnesians.

Infantry

The Achaemenid infantry consisted of three groups: the Immortals, the Sparabara, and the Takabara, though in the later years of the Achaemenid Empire, the Cardaces, were introduced.

The Immortals were described by Herodotus as being heavy infantry, led by Hydarnes, 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. They had wicker shields, short spears, swords or large daggers, bow and arrow. 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. Surviving Achaemenid coloured glazed bricks and carved reliefs represent the Immortals as wearing elaborate robes, hoop earrings and gold jewelry, though these garments and accessories were most likely worn only for ceremonial occasions. The Sparabara unit 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, they 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 counterattack. They were armoured with quilted linen and carried large rectangular wicker shields as a form of light manoeuvrable defense. This, however, left them at a severe disadvantage against heavily armoured opponents such as the hoplite, and his 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. The Takabara were a rare unit who were a tough type of peltasts. Takabara nevertheless were more garrison warriors than front line fighters as proved against the well-armed Hoplites of Greece where they were easily defeated in hand to hand conflict. They tended to fight with their own native weapons which would have included a crescent-shaped light wickerwork shield and axes as well as light linen cloth and leather. The Takabara were recruited from territories that incorporated modern Iraq and parts of Iran.

Cavalry

“ The armoured Persian horsemen and their death dealing chariots were invincible.

No man dared face them

” — Herodotus

The Persian Cavalry was crucial for conquering nations, and had maintained its importance in the Achaemenid army to the last days of the Achaemenid Empire. The cavalry were separated into four groups. The Chariot Archers, Horse cavalry, the Camel cavalry, and the Elephant Cavalry.

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 Spears, 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. 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 Spears, Swords, Bow, Arrow, and scale armour. The Persian Camel Cavalry was first introduced into the Persian army by Cyrus the Great, at the battle of Thymbra. The Persian war elephant was most likely introduced into the Persian army by Darius I after his conquest of the Indus Valley. They 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.

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 the Great (Darius I) is to be credited as the first Achaemenid king to invest in a Persian fleet. 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. 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.

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. Persian naval forces laid the foundation for a strong Persian maritime presence in the Persian Gulf. Persians were not only stationed on islands in the Persian Gulf, but also had ships often of 100 to 200 capacity patrolling the empire's various rivers including the Caroon or Karun ( Arabic name:Shatt-al-Arab), Tigris and Nile in the west, as well as the Indus.

The Achaemenid navy established bases located along the Shatt-al-Arab, Bahrain, Oman, and Yemen. The Persian fleet was not only used for peace-keeping purposes along the Shatt al-Arab but also opened the door to trade with India via the Persian Gulf. 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, reestablishing Achaemenid power in Ionia. Artaxerxes II would also utilize his navy to later on quell a rebellion in Egypt.

The construction material of choice was wood, but some armored 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.

Xenophon describes his eye-witness account of a massive military bridge created by joining 37 Persian ships across the Tigris river. The Persians utilized each boat's buoyancy, in order to support a connected bridge above which supply could be transferred. Herodotus also gives many accounts of Persians utilizing ships to build bridges. Darius the Great, 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. The bridge over the Bosphorus essentially connected the nearest tip of Asia to Europe, encompassing at least some 1000 meters of open water if not more. Herodotus describes the spectacle, and calls it the "bridge of Darius":

"Strait called Bosphorus, across which the bridge of Darius had been thrown is hundred and twenty furlongs in length, reaching from the Euxine, to the Propontis. The Propontis is five hundred furlongs across, and fourteen hundred long. Its waters flow into the Hellespont, the length of which is four hundred furlongs ..."

Years later, a similar boat bridge would be constructed by Xerxes the Great (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 spring of 327 BC

The ruins of Persepolis

Herodotus, in his mid-5th century BC account of Persian residents of the Pontus, reports that Persian youths, from their fifth year to their twentieth year, were instructed in three things – to ride a horse, to draw a bow, and to speak the Truth.

He further notes that:

the most disgraceful thing in the world [the Persians] think, is to tell a lie; the next worst, to owe a debt: because, among other reasons, the debtor is obliged to tell lies.

In Achaemenid Persia, the lie, druj, is considered to be a cardinal sin, and it was punishable by death in some extreme cases. Tablets discovered by archaeologists in the 1930s at the site of Persepolis give us adequate evidence about the love and veneration for the culture of truth during the Achaemenian period. These tablets contain the names of ordinary Persians, mainly traders and warehouse-keepers. According to Professor Stanley Insler of Yale University, as many as 72 names of officials and petty clerks found on these tablets contain the word truth. Thus, says Insler, we have Artapana, protector of truth, Artakama, lover of truth, Artamanah, truth-minded, Artafarnah, possessing splendour of truth, Artazusta, delighting in truth, Artastuna, pillar of truth, Artafrida, prospering the truth and Artahunara, having nobility of truth. It was Darius the Great who laid down the ordinance of good regulations during his reign. King Darius' testimony about his constant battle against the lie is found in cuneiform inscriptions. Carved high up in the Behistun mountain on the road to Kermanshah, Darius the Great (Darius I) testifies:

I was not a lie-follower, I was not a doer of wrong ... According to righteousness I conducted myself. Neither to the weak or to the powerful did I do wrong. The man who cooperated with my house, him I rewarded well; who so did injury, him I punished well.

Darius had his hands full dealing with large-scale rebellion which broke out throughout the empire. After fighting successfully with nine traitors in a year, Darius records his battles against them for posterity and tells us how it was the lie that made them rebel against the empire. At Behistun, Darius says:

I smote them and took prisoner nine kings. One was Gaumata by name, a Magian; he lied; thus he said: I am Smerdis, the son of Cyrus ... One, Acina by name, an Elamite; he lied; thus he said: I am king in Elam ... One, Nidintu-Bel by name, a Babylonian; he lied; thus he said: I am Nebuchadnezzar, the son of Nabonidus.

King Darius then tells us,

The Lie made them rebellious, so that these men deceived the people.

Then advice to his son Xerxes, who is to succeed him as the great king:

Thou who shalt be king hereafter, protect yourself vigorously from the Lie; the man who shall be a lie-follower, him do thou punish well, if thus thou shall think. May my country be secure!

Languages

During the reign of Cyrus and Darius, and as long as the seat of government was still at Susa in Elam, the language of the chancellory was Elamite. This is primarily attested in the Persepolis fortification and treasury tablets that reveal details of the day-to-day functioning of the empire. In the grand rock-face inscriptions of the kings, the Elamite texts are always accompanied by Akkadian (Babylonian dialect) and Old Persian inscriptions, and it appears that in these cases, the Elamite texts are translations of the Old Persian ones. It is then likely that although Elamite was used by the capital government in Susa, it was not a standardized language of government everywhere in the empire. The use of Elamite is not attested after 458 BC.

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." 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. Frye reclassifies Imperial Aramaic as the lingua franca of the Achaemenid territories, suggesting then that the Achaemenid-era use of Aramaic was more pervasive than generally thought. Many centuries after the fall of the empire, Aramaic script and – as ideograms – Aramaic vocabulary would survive as the essential characteristics of the Pahlavi writing system.

Although Old Persian also appears on some seals and art objects, that language is attested primarily in the Achaemenid inscriptions of Western Iran, suggesting then that Old Persian was the common language of that region. However, by the reign of Artaxerxes II, the grammar and orthography of the inscriptions was so "far from perfect" that it has been suggested that the scribes who composed those texts had already largely forgotten the language, and had to rely on older inscriptions, which they to a great extent reproduced verbatim.

When the occasion demanded, Achaemenid administrative correspondence was conducted in Greek, making it a widely used bureaucratic language. Even though the Achaemenids had extensive contacts with the Greeks and vice versa, and had conquered many of the Greek-speaking areas both in Europe and Asia Minor during different periods of the empire, the native Old Iranian sources provide no indication of Greek linguistic evidence. However, there is plenty of evidence (in addition to the accounts of Herodotus) that Greeks, apart from being deployed and employed in the core regions of the empire, also evidently lived and worked in the heartland of the Achaemenid Empire, namely Iran. For example, Greeks were part of the various ethnicities that constructed Darius' palace in Susa, apart from the Greek inscriptions found nearby there, and one short Persepolis tablet written in Greek.

Customs

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. Bowing to superiors, or royalty was one of the many Persian customs adopted by Alexander the Great.

Religion

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 Iranian pantheon but also introduced several novel ideas, including that of free will.

Under the patronage of the Achaemenid kings, and by the 5th century BC as the de facto religion of the state, Zoroastrianism reached all corners of the empire. The Bible claims that Cyrus the Great allowed the Jews to return to their homeland after decades of captivity by the Assyrian and Babylonian empires.

During the reign of Artaxerxes I and Darius II, Herodotus wrote "[the Perses] 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." 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." (The original name here is Mithra, which has since been explained to be a confusion of Anahita with Mithra, understandable since they were commonly worshipped together in one temple).

From the Babylonian scholar-priest Berosus, who—although writing over seventy years after the reign of Artaxerxes II Mnemon—records 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. 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." This sentence has been interpreted to identify a critical (but later) accretion to Zoroastrianism. An altar with a wood-burning fire and the Yasna service at which libations are poured are all clearly identifiable with modern Zoroastrianism, but apparently, were practices that had not yet developed in the mid-5th century. Boyce also assigns that development to the reign of Artaxerxes II (4th century BC), as an orthodox response to the innovation of the shrine cults.

Herodotus also observed that "no prayer or offering can be made without a magus present" but this should not be confused with what is today understood by the term magus, that is a magupat (modern Persian: mobed), a Zoroastrian priest. Nor does Herodotus' description of the term as one of the tribes or castes of the Medes necessarily imply that these magi were Medians. They simply were a hereditary priesthood to be found all over Western Iran and although (originally) not associated with any one specific religion, they were traditionally responsible for all ritual and religious services. Although the unequivocal identification of the magus with Zoroastrianism came later (Sassanid era, 3rd–7th century AD), it is from Herodotus' magus of the mid-5th century that Zoroastrianism was subject to doctrinal modifications that are today considered to be revocations of the original teachings of the prophet. Also, many of the ritual practices described in the Avesta's Vendidad (such as exposure of the dead) were already practiced by the magu of Herodotus' time.

Art and architecture

Achaemenid architecture includes large cities, temples, palaces, and mausoleums such as the tomb of Cyrus the Great. The quintessential feature of Persian 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.

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 took artists, with their styles and techniques, from all corners of their empire, they produced not simply a combination of styles, but a synthesis of a new unique Persian style. Cyrus the Great in fact had an extensive ancient Iranian heritage behind him; the rich Achaemenid gold work, which inscriptions suggest may have been a specialty of the Medes, was for instance in the tradition of the delicate metalwork found in Iron Age II times at Hasanlu and still earlier at Marlik.

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 his palace at Susa, Darius the Great records that:

Yaka timber was brought from Gandara and from Carmania. The gold was brought from Sardis and from Bactria ... the precious stone lapis-lazuli and carnelian ... was brought from Sogdiana. The turquoise from Chorasmia, the silver and ebony from Egypt, the ornamentation from Ionia, the ivory from Ethiopia and from Sindh and from Arachosia. The stone-cutters who wrought the stone, those were Ionians and Sardians. The goldsmiths were Medes and Egyptians. The men who wrought the wood, those were Sardians and Egyptians. The men who wrought the baked brick, those were Babylonians. The men who adorned the wall, those were Medes and Egyptians.

This was imperial art on a scale the world had not seen before. Materials and artists were drawn from all corners of the empire, and thus tastes, styles, and motifs became mixed together in an eclectic art and architecture that in itself mirrored the Persian empire.

Tomb of Artaxerxes II in Persepolis

Tombs

Many Achaemenid rulers built tombs for themselves. The most famous, Naqsh-e Rustam, is an ancient necropolis located about 12 km northwest of Persepolis, with the tombs of four of the kings of the dynasty carved in this mountain: Darius I, Xerxes I, Artaxerxes I and Darius II. Other kings constructed their own tombs elsewhere. Artaxerxes II and Artaxerxes III preferred to carve their tombs beside their summer capital Persepolis, the left tomb belonging to Artaxerxes II and the right tomb belonging 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).

Legacy

The Achaemenid Empire left a lasting impression on the heritage and the cultural identity of Asia, Europe, and the Middle East, as well as influencing the development and structure of future empires. In fact the Greeks and later on the Romans copied the best features of the Persian method of governing the empire, and vicariously adopted them.

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;

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 dependant, 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 ... 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.

The famous American orientalist, Professor Arthur Upham Pope (1881–1969) said: "The western world has a vast unpaid debt to the Persian Civilization!"

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

For thousands of years Persians have been creating beauty. Sixteen centuries before Christ there went from these regions or near it ... 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 ... 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, equaled before our time only by the zenith of Imperial Rome.
