The Achaemenid Empire (pron.: //; Old Persian: Parsā, name of ruling dynasty: Haxāmanišiya) (c. 550–330 BC), also known as the First Persian Empire, was a Persian empire in Western Asia, founded in the 6th century BC by Cyrus the Great who overthrew the Median confederation. The dynasty draws its name from king Achaemenes, who ruled Persia between 705 BC and 675 BC. The empire expanded to eventually rule over significant portions of the ancient world which at around 500 BC stretched from the Indus Valley in the east, to Thrace and Macedon on the northeastern border of Greece, making it the biggest empire the world had yet seen. The Achaemenid Empire would eventually control Egypt as well. It was ruled by a series of monarchs who unified its disparate tribes and nationalities by constructing a complex network of roads.
Calling themselves the Pars after their original Aryan tribal name Parsa, Persians settled in a land which they named Parsua (Persis in Greek), bounded on the west by the Tigris River and on the south by the Persian Gulf. This became their heartland for the duration of the Achaemenid Empire. It was from this region that eventually Cyrus the Great (Cyrus II of Persia) would advance to defeat the Median, the Lydian, and the Babylonian Empires, opening the way for subsequent conquests into Egypt and Asia Minor.
At the height of its power after the conquest of Egypt, the empire encompassed approximately 8 million square kilometers spanning three continents: Asia, Africa and Europe. At its greatest extent, the empire included the modern territories of Iran, Iraq, Syria, Jordan, Israel, Palestine, Lebanon, all significant population centers of ancient Egypt as far west as Libya, Turkey, Thrace and Macedonia, much of the Black Sea coastal regions, Armenia, Georgia, Azerbaijan, much of Central Asia, Afghanistan, northern Saudi Arabia, Pakistan, and parts of Oman and the UAE. It is noted in Western history as the antagonist foe of the Greek city states during the Greco-Persian Wars, for emancipation of slaves including the Jewish people from their Babylonian captivity, and for instituting infrastructures such as a postal system, road systems, and the usage of an official language, Aramaic, throughout its territories. The empire had a centralised, bureaucratic administration under the King and a large professional army and civil services, inspiring similar developments in later empires. The delegation of power to local governments eventually weakened the king's central authority, causing resources to be expended in attempts to subdue local rebellions. This accounts for the dis-unification of the region by the time Alexander the Great invaded Persia 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 cause the collapse of the empire and its disintegration around 330 BC into what later became the Ptolemaic Kingdom and Seleucid Empire, in addition to other minor territories which gained independence at that time. The Iranian Culture of the central plateau, however, continued to thrive and eventually reclaimed power by the 2nd century BC.
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 the Great's Edict of Restoration is mentioned in Judeo-Christian texts and the empire was instrumental in the spread of Zoroastrianism as far east as China. Even Alexander the Great, the man who would set out to conquer this vast empire, would respect its customs, by enforcing respect for the royal Persian kings including Cyrus the Great, and even by appearing in proskynesis, a Persian royal custom, despite stern Macedonian disapproval. The Persian empire would also set the tone for the politics, heritage and history of modern Persia (now called 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 Persian Empire is named after an Indo-European tribe called Parsua. The name Persia is a Latin pronunciation of the Indo-Iranian people Parsua who named their territorial borders Persis, after their tribal name, an area located north of the Persian Gulf and East of Tigris river referred to as Persis (or in Persian, Pars).
Despite its success and rapid expansion, Achaemenid empire was not the first Iranian empire, as by 6th century BC another group of ancient Iranian people had already established the Median Empire. The Medes had originally been the dominant Irania group in the region, rising to power at the end of the 7th century BC and incorporating the Persians into their empire. The Iranian peoples had arrived in the region circa 1000 BC and had initially fallen under the domination of the Assyrian Empire (911-609 BC). However, the Medes and Persians, (together with the Scythians and Babylonia) played a major role in the destruction of an Assyria riven by internal strife.
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 7th-century ruler of the Anshan (Ansham or Anšān) located 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, to become the vast Persian empire of which the ancient texts speak.
At some point in 550 BC, Cyrus the Great rose in rebellion against the Median empire (most likely due to the Medes' mismanagement of Persis), eventually conquering the Medes and creating the first Persian empire. Cyrus the Great would utilize his tactical genius, as well as his understanding of the socio-political equations governing his territories, to eventually incorporate into the Persian empire the neighbouring Lydian and Neo-Babylonian empires, and also leading the way for his successor, Cambyses II to venture into Egypt and defeat the Egyptian Kingdom.
Cyrus the Great would reflect his political acumen in the 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 would agree 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 would ultimately become 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, weakening the central power of the king. By the time of Darius III, this disorganization had almost led to a disunified realm.
The Persians from whom Cyrus hailed were originally nomadic pastoral people 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 (Pars). 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 the Great (Darius I), and completed some 100 years later, Persepolis was a symbol of the empire serving both as a ceremonial centre and a center for 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, erect, decorated columns would often welcome visitors as well as impress them as to the size of the structure. Later on, Darius the Great (Darius I), would also utilize Susa and Ecbatana as his governmental centres, developing them into a similar metropolis status.
Account of the ancestral lineage of the Persian kings of the Achaemenid dynasty 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 much of the original Persian documents are lost, not to mention 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 the Great (Cyrus II of Persia), and Darius the Great (Darius I of Persia), were critical in expansion of the empire. Cyrus the Great is often believed to be the son of Cambyses I, grandson of Cyrus I, the father of Cambyses II, and a relative of Darius the Great, 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, Mandana of Media. A minority of scholars argue that perhaps Achaemenes was a retrograde creation of Darius the Great, in order to reconcile his connection with Cyrus the Great, 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 Perses were different people, and that Perses was an ancestor of the king. This account further confirms that Achaemenes could well have been a significiant 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.
Formation and expansion 
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 Egypt and Asia Minor. 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 II 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 as the result of an injurious self-accident, during a revolt led by a sacerdotal clan that had lost its power following Cyrus' conquest of Media. 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 council man serving Amasis, further enforced 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 (Herodotus iii. 68). Cambyses II himself would not be able to quell the imposters, as he died due to accidental injury 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.
Darius the Great (Darius I) eventually attacked the Greek mainland, which had supported rebellious Greek colonies under his aegis; but as a result of his defeat at the Battle of Marathon, he was forced to pull the limits of his empire back to Asia Minor. Some scholars argue that in the context of history of the Near and Middle east in the first millennium, Alexander can be considered as the "last of the Achaemenids." This is partly because Alexander maintained more or less the same political structure, and borders as the previous Achaemenid kings.
Greco-Persian Wars 
By the 5th century BC the Kings of Persia were either ruling over or had subordinated territories roughly encompassing today's Iran, Iraq, Syria, Jordan, Lebanon, Israel/ Palestine, Kuwait, Egypt, northern Libya, Turkey, Cyprus, parts of Greece, Macedonia (ancient kingdom), Bulgaria, Georgia, Armenia, Azerbaijan, Turkmenistan, Tajikistan, Kyrgyzstan, Uzbekistan, Afghanistan, parts of northern Arabia, and some parts of north-western India/ Pakistan.
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 for 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. However, the Persian forces were defeated at the Battle of Marathon and Darius would die before having the chance to launch an invasion of Greece.
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 marked the end of Persian expansion into Europe.
The cultural phase 
Xerxes I was followed by Artaxerxes I (465–424 BC), who moved the capital from Persepolis to Babylon. It was during this 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.
Artaxerxes I died in Susa, and his body was brought to Persepolis for interment in the tomb of his forebears. Artaxerxes I was immediately succeeded by his eldest son Xerxes II, who was however assassinated by one of his half-brothers a few weeks later. Darius II rallied support for himself and marched eastwards, executing the assassin and was crowned in his stead.
From 412 Darius II (423–404 BC), at the insistence of the able 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. At his deathbed, his Babylonian wife Parysatis pleaded with Darius to have her second eldest son Cyrus (the Younger) crowned, but Darius refused.
Darius was then succeeded by his eldest son Artaxerxes II Memnon. 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 and Artaxerxes met in the Battle of Cunaxa in 401 BC, where Cyrus was killed.
Artaxerxes II (404–358 BC), 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 (Polybius, 27 October 2012). The extraordinary innovation of the Zoroastrian shrine cults can also be dated to his reign, and it was probably during this period that Zoroastrianism was disseminated throughout Asia Minor and the Levant, from Armenia. The temples, though serving a religious purpose, were however not a purely selfless act: 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 (Dandamaev & Lukonin, 1989:361–362). A share of this income called the quppu ša šarri, "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.
Fall of the empire 
According to Plutarch, Artaxerxes' successor Artaxerxes III (358 – 338 BC) came to the throne by bloody means, ensuring his place upon the throne by the assassination of eight of his half-brothers. In 343 BC Artaxerxes III defeated Nectanebo II, driving him from Egypt, and made Egypt once again a Persian satrapy. In 338 BC Artaxerxes III died under unclear circumstances (natural causes according to cuneiform sources but Diodorus, a Greek historian, reports that Artaxerxes was murdered by Bagoas, his minister). while Philip of Macedon united the Greek states by force and began to plan an invasion into 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 (336–330 BC), 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.
At two different times, the Achaemenids ruled Egypt although the Egyptians twice regained temporary independence from Persia. After the practice of Manetho, Egyptian historians refer to the periods in Egypt when the Achaemenid dynasty ruled as the twenty-seventh dynasty of Egypt, 525–404 BC, until the death of Darius II, and the thirty-first dynasty of Egypt, 343–332 BC, which began after Nectanebo II was defeated by the Persian king Artaxerxes III.
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 Cyropedia.
In the ensuing chaos created by Alexander the Great's invasion of Persia, Cyrus the Great's tomb was broken into and most of its luxuries were looted. When Alexander the Great reached the tomb, he was horrified by the manner in which the tomb was treated, and questioned the Magi, putting them to court. On some accounts, Alexander's decision to put the Magi on trial was more about his attempt to undermine their influence and his show of power in his newly conquered empire, than a 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".
Despite having succeeded to conquer the whole of the Persian empire, Alexander the Great, was nonetheless unable to offer a stable alternative. After his death, Alexander's once massive Hellenistic empire was broken into and succeeded by few smaller empires the most significant of which was the Seleucid Empire, ruled by the generals of Alexander and their descendants. They in turn would be succeeded by the Parthian Empire.
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.
Descendants in later Iranian dynasties 
Both the later dynasties of the Parthians and Sassanids and Gabaris 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.
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 vassal king, 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 moved the capital from Pasargadae to Persepolis; 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; the province consisting of the sindh and western Punjab regions of ancient northwestern India traded gold dust equal in value to the very large amount of 4680 silver talents for various commodities. 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. 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 king also maintained a personal bodyguard of the elite 10,000 Immortals when not at war.
The practice of slavery in Achaemenid Persia was generally banned, although there is evidence that conquered and/or rebellious armies were sold into captivity. Zoroastrianism, the de facto religion of the empire, explicitly forbids slavery, and the kings of Achaemenid Persia, especially the founder Cyrus the Great, followed this ban to varying degrees, as evidenced by the freeing of the Jews at Babylon, and the construction of Persepolis by paid workers.
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.
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, Cypriots, 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. Despite origin of the technique of the arsenal and ship construction in Sidon, 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, that existed until the arrival of the British East India Company, and the Royal Navy in the mid-19th century CE. Persians were not only stationed on islands of the Persian Gulf, but also had ships often of 100 to 200 capacity patrolling the empire's various rivers including the Shatt-al-Arab, Tigris and Nile in the west, as well as the Sind waterway in India.
The Achaemenid high naval command had established major naval bases located along the Shatt-al-Arab, Bahrain, Oman, and Yemen. The Persian fleet would soon not only be used for peace-keeping purposes along the Shatt al-Arab but would also open 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 massive 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. That is, in fact very smart of the Persians. 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, encompasing 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
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 an 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!
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 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.
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.
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, III.65). 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 CE), 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 refers to the architectural achievements of the Achaemenid Persians manifesting in construction of spectacular cities utilized for governance and inhabitation, temples made for worship and social gatherings (such as Zoroastrian temples), and mausoleums erected in honor of fallen kings (such as the burial 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 refers to the artistic achievements of the Achaemenid Persians manifesting in construction of complicated frieze reliefs, crafting of precious metals (such as the Oxus Treasure), decoration of palaces, glazed brick masonry, fine craftsmanship (masonry, carpentry, etc.), and gardening, and out door decoration. It is critical to understand that although Persians borrowed techniques from all corners of their empire, it was not simply a combination of styles, but 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 amazing 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.
The Achaemenid Empire left a lasting impression on the heritage and the cultural identity of Asia and 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.
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.

"Of the four residences of the Achaemenids named by Herodotus — Ecbatana, Pasargadae or Persepolis, Susa and Babylon — the last [situated in Iraq] was maintained as their most important capital, the fixed winter quarters, the central office of bureaucracy, exchanged only in the heat of summer for some cool spot in the highlands. Under the Seleucids and the Parthians the site of the Mesopotamian capital moved a little to the north on the Tigris — to Seleucia and Ctesiphon. It is indeed symbolic that these new foundations were built from the bricks of ancient Babylon, just as later Baghdad, a little further upstream, was built out of the ruins of the Sassanian double city of Seleucia-Ctesiphon."
