The Achaemenid conquest of the Indus Valley occurred from the 6th to 4th centuries BCE, and saw the Persian Achaemenid Empire take control of regions in the northwestern Indian subcontinent that predominantly comprise the territory of modern-day Pakistan. The first of two main invasions was conducted around 535 BCE by the empire's founder, Cyrus the Great, who annexed the regions west of the Indus River that formed the eastern border of the Achaemenid Empire. Following Cyrus' death, Darius the Great established his dynasty and began to re-conquer former provinces and further expand the empire. Around 518 BCE, Persian armies under Darius crossed the Himalayas into India to initiate a second period of conquest by annexing regions up to the Jhelum River in Punjab.
The first secure epigraphic evidence through the Behistun Inscription gives a date before or around 518 BCE. Achaemenid penetration into the Indian subcontinent occurred in stages, starting from northern parts of the Indus River and moving southward. The Indus Valley was formally incorporated into the Achaemenid Empire as the satrapies of Gandāra, Hindush, and Sattagydia, as mentioned in several Achaemenid-era Persian inscriptions.
Achaemenid rule over the Indus Valley decreased over successive rulers and formally ended around the time of the Macedonian conquest of Persia under Alexander the Great. This gave rise to independent kings such as Abisares, Porus (ruler of the region between the Jhelum and Chenab rivers), Ambhi (ruler of the region between the Indus and Jhelum rivers with its capital at Taxila) as well as gaṇasaṅghas, or republics, which later confronted Alexander during his Indian campaign around 323 BCE. The Achaemenid Empire set a precedence of governance through the use of satrapies, which was further implemented by Alexander's Macedonian Empire, the Indo-Scythians, and the Kushan Empire.
For millennia, the northwestern part of India had maintained some level of trade relations with the Near East. Finally, the Achaemenid Empire underwent a considerable expansion, both east and west, during the reign of Cyrus the Great (c.600–530 BC), leading the dynasty to take a direct interest into the region of northwestern India.
The conquest is often thought to have started circa 535 BCE, during the time of Cyrus the Great (600-530 BCE). Cyrus probably went as far as the banks of the Indus river and organized the conquered territories under the Satrapy of Gandara (Old Persian cuneiform: 𐎥𐎭𐎠𐎼, Gadāra, also transliterated as Gandāra since the nasal "n" before consonants was omitted in the Old Persian script, and simplified as Gandara) according to the Behistun Inscription. The Province was also referred to as Paruparaesanna (Greek: Parapamisadae) in the Babylonian and Elamite versions of the Behistun inscription. The geographical extent of this province was wider than the Indian Gandhara. Various accounts, such as those of Xenophon or Ctesias, who wrote Indica, also suggest that Cyrus conquered parts of India. Another Indian Province was conquered named Sattagydia (𐎰𐎫𐎦𐎢𐏁, Thataguš) in the Behistun inscription. It was probably contiguous to Gandhara, but its actual location is uncertain. Fleming locates it between Arachosia and the middle Indus. Fleming also mentions Maka, in the area of Gedrosia, as one of the Indian satrapies.
A successor of Cyrus the Great, Darius I was back in 518 BCE. The date of 518 BCE is given by the Behistun inscription, and is also often the one given for the secure occupation of Gandhara in Punjab. Darius I later conquered an additional province that he calls "Hidūš" in his inscriptions (Old Persian cuneiform: 𐏃𐎡𐎯𐎢𐏁, H-i-du-u-š, also transliterated as Hindūš since the nasal "n" before consonants was omitted in the Old Persian script, and simplified as Hindush), corresponding to the Indus Valley. The Hamadan Gold and Silver Tablet inscription of Darius I also refers to his conquests in India.
The exact area of the Province of Hindush is uncertain. Some scholars have described it as the middle and lower Indus Valley and the approximate region of modern Sindh, but there is no known evidence of Achaemenid presence in this region, and deposits of gold, which Herodotus says was produced in vast quantities by this Province, are also unknown in the Indus delta region. Alternatively, Hindush may have been the region of Taxila and Western Punjab, where there are indications that a Persian satrapy may have existed. There are few remains of Achaemenid presence in the east, but, according to Fleming, the archaeological site of Bhir Mound in Taxila remains the "most plausible candidate for the capital of Achaemenid India", based on the fact that numerous pottery styles similar to those of the Achaemenids in the East have been found there, and that "there are no other sites in the region with Bhir Mound's potential".
According to Herodotus, Darius I sent the Greek explorer Scylax of Caryanda to sail down the Indus river, heading a team of spies, in order to explore the course of the Indus river. After a periplus of 30 months, Scylax is said to have returned to Egypt near the Red Sea, and the seas between the Near East and India were made use of by Darius.
Also according to Herodotus, the territories of Gandhara, Sattagydia, Dadicae and Aparytae formed the 7th province of the Achaemenid Empire for tax-payment purposes, while Indus (called Ἰνδός, "Indos" in Greek sources) formed the 20th tax region.

Throughout its existence, the Achaemenid were constantly engaging in wars. Either through conquering new territories or by quelling rebellions throughout the empire. To fulfil this need, the Achaemenid Empire had to maintain a professional standing army which levied and employed personnel from all of its satraps and territories.
The Achaemenid army was not uniquely Persian. Rather it was composed of many different ethnicities that were part of the vast and diverse Achaemenid Empire. Herodotus gives a full list of the ethnicities of the Achaemenid army, in which are included Bactrians, Sakas (Scythians), Parthians, Sogdians. Ionians (Greeks), Egyptians, Ethiopians, etc. These ethnicities are likely to have been included in the Achaemenid army during the invasions of India.
These events were recorded in the imperial inscriptions of the Achaemenids (the Behistun inscription and the Naqsh-i-Rustam inscription, as well as the accounts of Herodotus (483–431 BCE). The Greek Scylax of Caryanda, who had been appointed by Darius I to explore the Indian Ocean from the mouth of the Indus to Suez left an account, the Periplous, of which fragments from secondary sources have survived. Hecataeus of Miletus (circa 500 BCE) also wrote about the "Indus Satrapies" of the Achaemenids.
The 'DB' Behistun inscription of Darius I (circa 510 BCE) mentions Gandara (𐎥𐎭𐎠𐎼, Gadāra) and the adjacent territory of Sattagydia (𐎰𐎫𐎦𐎢𐏁, Thataguš) as part of the Achaemenid Empire:
King Darius says: These are the countries which are subject unto me, and by the grace of Ahuramazda I became king of them: Persia [Pârsa], Elam [Ûvja], Babylonia [Bâbiruš], Assyria [Athurâ], Arabia [Arabâya], Egypt [Mudrâya], the countries by the Sea, Lydia [Sparda], the Greeks [Yauna (Ionia)], Media [Mâda], Armenia [Armina], Cappadocia [Katpatuka], Parthia [Parthava], Drangiana [Zraka], Aria [Haraiva], Chorasmia [Uvârazmîy], Bactria [Bâxtriš], Sogdia [Suguda], Gandara [Gadāra], Scythia [Saka], Sattagydia [Thataguš], Arachosia [Harauvatiš] and Maka [Maka]; twenty-three lands in all.
From the dating of the Behistun inscription, it is possible to infer that the Achaemenids first conquered the areas of Gandara and Sattagydia circa 518 BCE.
Hinduš is also mentioned as one of 24 subject countries of the Achaemenid Empire, illustrated with the drawing of a kneeling subject and a hieroglyphic cartridge reading 𓉔𓈖𓂧𓍯𓇌 (h-n-d-wꜣ-y), on the Egyptian Statue of Darius I, now in the National Museum of Iran. Sattagydia also appears (𓐠𓂧𓎼𓍯𓍒, sꜣ-d-g-wꜣ-ḏꜣ, Sattagydia), and probably Gandara (𓉔𓃭𓐍𓂧𓇌, h-rw-ḫ-d-y, although this could be Arachosia), with their own illustrations.
Four identical foundation tablets of gold and silver, found in two deposition boxes in the foundations of the Apadana Palace, also contained an inscription by Darius I in Old Persian cuneiform, which describes the extent of his Empire in broad geographical terms, from the Indus valley in the east to Lydia in the west, and from the Scythians beyond Sogdia in the north, to the African Kingdom of Kush in the south. This is known as the DPh inscription. The deposition of these foundation tablets and the Apadana coin hoard found under them, is dated to circa 515 BCE.
Darius the great king, king of kings, king of countries, son of Hystaspes, an Achaemenid. King Darius says: This is the kingdom which I hold, from the Sacae who are beyond Sogdia to Kush, and from Sind (Old Persian: 𐏃𐎡𐎭𐎢𐎺, "Hidauv", locative of "Hiduš", i.e. "Indus valley") to Lydia (Old Persian: "Spardâ") - [this is] what Ahuramazda, the greatest of gods, bestowed upon me. May Ahuramazda protect me and my royal house!— DPh inscription of Darius I in the foundations of the Apadana Palace
The DSe inscription and DSm inscription of Darius in Susa gives Thataguš (Sattagydia), Gadāra (Gandara) and Hiduš (Sind) among the nations that he rules.
Hidūš (𐏃𐎡𐎯𐎢𐏁 in Old Persian cuneiform) also appears later as a Satrapy in the Naqsh-i-Rustam inscription at the end of the reign of Darius, who died in 486 BCE. The DNa inscription on Darius' tomb at Naqsh-i-Rustam near Persepolis records Gadāra (Gandāra) along with Hiduš and Thataguš (Sattagydia) in the list of satrapies.
King Darius says: By the favor of Ahuramazda these are the countries which I seized outside of Persia; I ruled over them; they bore tribute to me; they did what was said to them by me; they held my law firmly; Media, Elam, Parthia, Aria, Bactria, Sogdia, Chorasmia, Drangiana, Arachosia, Sattagydia, Gandara (Gadāra), India (Hiduš), the haoma-drinking Scythians, the Scythians with pointed caps, Babylonia, Assyria, Arabia, Egypt, Armenia, Cappadocia, Lydia, the Greeks (Yauna), the Scythians across the sea (Sakâ), Thrace, the petasos-wearing Greeks [Yaunâ], the Libyans, the Nubians, the men of Maka and the Carians.— Naqsh-e Rustam inscription of Darius I (circa 490 BCE)
The extent of Achaemenid territories is also affirmed by Strabo in his "Geography" (Book XV), describing the Persian holdings along the Indus:
The geographical position of the tribes is as follows: along the Indus are the Paropamisadae, above whom lies the Paropamisus mountain: then, towards the south, the Arachoti: then next, towards the south, the Gedroseni, with the other tribes that occupy the seaboard; and the Indus lies, latitudinally, alongside all these places; and of these places, in part, some that lie along the Indus are held by Indians, although they formerly belonged to the Persians.
The nature of the administration under the Achaemenids is uncertain. Even though the Indian provinces are called "satrapies" by convention, there is no evidence of there being any satraps in these provinces. When Alexander invaded the region, he did not encounter Achaemenid satraps in the Indian provinces, but local Indian rulers referred to as hyparchs ("Vice-Regents"), a term that connotes subordination to the Achaemenid rulers. The local rulers may have reported to the satraps of Bactria and Arachosia.
Darius I listed three Indian provinces: Sattagydia (Thataguš), Gandāra (Gandhara) and Hidūš (Sind), in which "Sind" should be understood as "Indus Valley".
Gandhara included the entire Peshawar Valley which was bound by the Swat District in the north, Afghanistan in the West, the Indus River to the south east, and Kohat District in the south. The capital of the Gandhara satrapy was Pushkalavati. Archeological excavations of Pushkalavati were conducted by Mortimer Wheeler in 1962 who discovered structures built during the Achaemenid period as well as artifacts.
The Achaemenid Satrapy of Hindush incorporated the Greater Punjab region in the Indus Valley. It was bound by the Hazara region to the north, the Indus River to the west, and the Jhelum River in the south and east. The satrapy's capital was Bhir Mound in Takshashila (Taxila). Bhir Mound was excavated by John Marshall between 1913 and 1934. Fortified structures and canals were found dating to the Achaemenid period, as well as ornamental jewelry.
The three regions remained represented among Achaemenid Provinces on all the tombs of the Achaemenid rulers after Darius, except for the last ruler Darius III who was vanquished by Alexander at Gaugamela, suggesting that the Indians were under Achaemenid dominion at least until 338 BCE, date of the end of the reign of Artaxerxes III, before the accession of Darius III, that is, less than 10 years before the campaigns of Alexander in the East and his victory at Gaugamela. The last known appearance of Gandhara in name as an Achaemenid province is on the list of the tomb of Artaxerxes II, circa 358 BCE, date of his burial.
Herodotus (III-91 and III-94), gives a list with a slightly different structure, as some province which are presented separately in the Achaemenid inscriptions are grouped together by Herodotus when he described the tribute paid by each territory. Herodotus presents Indos (Ἰνδός) as "the 20th province", while "the Sattagydae, Gandarii, Dadicae, and Aparytae" together form "the 7th Province". According to historian A. T. Olmstead, the fact that some Achaemenid regions are grouped together in this list may have represented some loss of territory.
The Hindūš province, remained loyal till Alexander's invasion. Circa 400 BC, Ctesias of Cnidus related that the Persian king was receiving numerous gifts from the kings of "India" (Hindūš).[a] Ctesias also reported Indian elephants and Indian mahouts making demonstrations of the elephant's strength at the Achaemenid court.
By about 380 BC, the Persian hold on the region was weakening, but the area continued to be a part of the Achaemenid Empire until Alexander's invasion.
Darius III (c. 380 – July 330 BC) still had Indian units in his army, albeit very few in comparison to his predecessors. In particular he had 15 war elephants at the Battle of Gaugamela for his fight against Alexander the Great.
The reliefs at the Apadana Palace in Persepolis describe tribute bearers from 23 satrapies visiting the Achaemenid court. These are located at the southern end of the Apadana Staircase. Among the foreigners the Arabs, the Thracians, the Bactrians, the Indians (from the Indus valley area), the Parthians, the Cappadocians, the Elamites or the Medians. The Indians from the Indus valley are bare-chested, except for their leader, and barefooted and wear the dhoti. They bring baskets with vases inside, carry axes, and drive along a donkey. One man in the Indian procession carries a small but visibly heavy load of four jars on a yoke, suggesting that he was carrying some of the gold dust paid by the Indians as tribute to the Achaemenid court.
According to the Naqsh-e Rustam inscription of Darius I (circa 490 BCE), there were three Achaemenid Satrapies in the subcontinent: Sattagydia, Gandara, Hidūš.

The conquered area was the most fertile and populous region of the Achaemenid Empire. An amount of tribute was fixed according to the richness of each territory. India was already fabled for its gold.
Herodotus (who makes several comments on India) published a list of tribute-paying nations, classifying them in 20 Provinces. The Province of Indos (Ἰνδός, the Indus valley) formed the 20th Province, and was the richest and most populous of the Achaemenid Provinces.
The Indians ( Ἰνδῶν) made up the twentieth province. These are more in number than any nation known to me, and they paid a greater tribute than any other province, namely three hundred and sixty talents of gold dust.
According to Herodotus, the "Indians" ('Ινδοι, Indoi)), as separate from the Gandarei and the Sattagydians, formed the 20th taxation Province, and were required to supply gold dust in tribute to the Achaemenid central government for an amount of 360 Euboean talents (equivalent to about 8300 kg or 8.3 tons of gold annually, a volume of gold that would fit in a cube of side 75 cm). The exchange rate between gold and silver at the time of Herodotus being 13 to 1, this was equal in value to the very large amount of 4680 Euboean talents of silver, equivalent to 3600 Babylonian talents of silver (equivalent in value to about 108 tons of silver annually). The country of the "Indians" ('Ινδοι, Indoi) was the Achaemenid district paying the largest tribute, and alone represented 32% of the total tribute revenues of the whole Achaemenid Empire. It also means that Indos was the richest Achaemenid region in the subcontinent, much richer than Gandara or Sattagydia. However the amount of gold in question is quite enormous, so there is a possibility that Herodotus was mistaken and that his own sources actually only meant something like the gold equivalent of 360 Babylonian talents of silver.
The territories of Gandara, Sattagydia, Dadicae (north-west of the Kashmir Valley) and the Aparytae (Afridis) are named separately, and were aggregated together for taxation purposes, forming the 7th Achaemenid Province, and paying overall a much lower tribute of 170 talents together (about 5151 kg, or 5.1 tons of silver), hence only about 1.5% of the total revenues of the Achaemenid Empire:
The Sattagydae (Σατταγύδαι), Gandarii (Γανδάριοι), Dadicae, and Aparytae (Ἀπαρύται) paid together a hundred and seventy talents; this was the seventh province
The Indians also supplied Yaka wood (teak) for the construction of Achaemenid palaces, as well as war elephants such as those used at Gaugamela. The Susa inscriptions of Darius explain that Indian ivory and teak were sold on Persian markets, and used in the construction of his palace.
Indians were employed in the Achaemenid army of Xerxes in the Second Persian invasion of Greece (480-479 BCE). All troops were stationned in Sardis, Lydia, during the winter of 481-480 BCE to prepare for the invasion. In the spring of 480 BCE "Indian troops marched with Xerxes's army across the Hellespont". It was the "first-ever force from India to fight on the continent of Europe", storming Greek troops at the Battle of Thermopylae in 480 BCE, and fighting as one of the main nations until the final Battle of Platea in 479 BCE.
Herodotus, in his description of the multi-ethnic Achaemenid army invading Greece, described the equipment of the Indians:
The Indians wore garments of tree-wool, and carried bows of reed and iron-tipped arrows of the same. Such was their equipment; they were appointed to march under the command of Pharnazathres son of Artabates.— Herodotus VII 65
Herodotus also explains that the Indian cavalry under the Achaemenids had an equipment similar that of their foot soldiers:
The Indians were armed in like manner as their foot; they rode swift horses and drove chariots drawn by horses and wild asses.— Herodotus VII 86
The Gandharis had a different equipment, akin to that of the Bactrians:
The Bactrians in the army wore a headgear most like to the Median, carrying their native bows of reed, and short spears. (...) The Parthians, Chorasmians, Sogdians, Gandarians, and Dadicae in the army had the same equipment as the Bactrians. The Parthians and Chorasmians had for their commander Artabazus son of Pharnaces, the Sogdians Azanes son of Artaeus, the Gandarians and Dadicae Artyphius son of Artabanus.— Herodotus VII 64-66
After the first part of the campaign directly under the orders Xerxes I, the Indian troops are reported to have stayed in Greece as one of the 5 main nations among the 300,000 elite troops of General Mardonius. They fought in the last stages of the war, took part in the Destruction of Athens, but were finally vanquished at the Battle of Platea:
Mardonius there chose out first all the Persians called Immortals, save only Hydarnes their general, who said that he would not quit the king's person; and next, the Persian cuirassiers, and the thousand horse, and the Medes and Sacae and Bactrians and Indians, alike their footmen and the rest of the horsemen. He chose these nations entire; of the rest of his allies he picked out a few from each people, the goodliest men and those that he knew to have done some good service... Thereby the whole number, with the horsemen, grew to three hundred thousand men.
At the final Battle of Platea in 479 BCE, Indians formed one of the main corps of Achaemenid troops (one of "the greatest of the nations"). They were one of the main battle corps, positioned near the center of the Achaemenid battle line, between the Bactrians and the Sakae, facing against the enemy Greek troops of "Hermione and Eretria and Styra and Chalcis". According to modern estimates, the Bactrians, Indians and Sakae probably numbered about 20,000 men altogether, whereas the Persian troops on their left amounted to about 40,000. There were also Greek allies of the Persians, positioned on the right, whom Herodotus numbers at 50,000, a number which however might be "extravagant", and is nowadays estimated to around 20,000. Indians also supplied part of the cavalry, the total of which was about 5,000.
Indian soldiers of the three territories of Gandara, Sattagydia (Tathagatus) and Hindush are shown, together with soldiers of all the other nations, supporting the throne of their Achaemenid ruler, at Naqsh-e Rostam on the tombs of Darius I, Xerxes I, Artaxerxes I and Darius II, and at Persepolis on the tombs of Artaxerxes II and Artaxerxes III. The last Achaemenid ruler Darius III never had time to finish his own tomb due to his hasty defeat by Alexander the Great, and therefore does not have such depictions. The soldiers from India are characterized by their particular clothing, only composed of a loin cloth and sandals, with bare upper body, in contrast to all the other ethnicities of the Achaemenid army, who are fully clothed, and in contrast also to the neighbouring provinces of Bactria or Arachosia, who are also fully clothed.
The presence of the three ethnicities of Indian soldiers on all the tombs of the Achaemenid rulers after Darius, except for the last ruler Darius III who was vanquished by Alexander at Gaugamela, suggests that the Indians were under Achaemenid dominion at least until 338 BCE, the date of the end of the reign of Artaxerxes III, before the accession of Darius III, that is, less than 10 years before the campaigns of Alexander in the East and his victory at Gaugamela.
According to Arrian, Indian troops were still deployed under Darius III at the Battle of Gaugamela (331 BCE). He explains that Darius III "obtained the help of those Indians who bordered on the Bactrians, together with the Bactrians and Sogdianians themselves, all under the command of Bessus, the Satrap of Bactria". The Indians in questions were probably from the area of Gandara. Indian "hill-men" are also said by Arrian to have joined the Arachotians under Satrap Barsentes, and are thought to have been either the Sattagydians or the Hindush.
Fifteen Indian war elephants were also part of the army of Darius III at Gaugamela. They had specifically been brought from India. Still, it seems they did not participate to the final battle, probably because of fatigue. This was a relief for the armies of Alexander, who had no previous experience of combat against war elephants. The elephants were captured with the baggage train by the Greeks after the engagement.

Coins found in the Chaman Hazouri hoard in Kabul, the Shaikhan Dehri hoard in Pushkalavati in Gandhara, near Charsadda, as well as in the Bhir Mound hoard in Taxila, have revealed numerous Achaemenid coins as well as many Greek coins from the 5th and 4th centuries BCE. These circulated in the area, at least as far as the Indus during the reign of the Achaemenids, who were in control of the areas as far as Gandhara.
See also: Kabul hoard
The Kabul hoard, also called the Chaman Hazouri, Chaman Hazouri or Tchamani-i Hazouri hoard, is a coin hoard discovered in the vicinity of Kabul, Afghanistan. The hoard, discovered in 1933, contained numerous Achaemenid coins as well as many Greek coins from the 5th and 4th centuries BCE. Approximately one thousand coins were in the hoard. The hoard is dated to approximately 380 BCE as no coins in the hoard were later than that date.
This numismatic discovery has been very important in studying and dating the history of coinage of India, since it is one of the very rare instances when punch-marked coins can actually be dated, due to their association with known and dated Greek and Achaemenid coins in the hoard. The hoard supports the view that punch-marked coins existed in 360 BCE, as suggested by literary evidence.
Daniel Schlumberger also considers that punch-marked bars, similar to the many punch-marked bars found in north-western India, initially originated in the Achaemenid Empire, rather than in the Indian heartland:
"The punch-marked bars were up to now considered to be Indian (...) However the weight standard is considered by some expert to be Persian, and now that we see them also being uncovered in the soil of Afghanistan, we must take into account the possibility that their country of origin should not be sought beyond the Indus, but rather in the oriental provinces of the Achaemenid Empire"— Daniel Schlumberger, quoted from Trésors Monétaires, p.42.
Modern numismatists now tend to consider the Achaemenid punch-marked coins as the precursors of the Indian punch-marked coins.
See also: Shaikhan Dehri hoard
In 2007, a small coin hoard was discovered at the site of ancient Pushkalavati (the Shaikhan Dehri hoard) near Charsada in Pakistan. The hoard contained a tetradrachm minted in Athens circa 500/490-485/0 BCE, typically used as a currency for trade in the Achaemenid Empire, together with a number of local types as well as silver cast ingots. The Athens coin is the earliest known example of its type to be found so far to the east.
According to Joe Cribb, these early Greek coins were at the origin of Indian punch-marked coins, the earliest coins developed in India, which used minting technology derived from Greek coinage.
Taxila (site of Bhir Mound), the "most plausible candidate for the capital of Achaemenid India", was at the crossroad of the main trade roads of Asia, was probably populated by Persians, Greeks and other people from throughout the Achaemenid Empire. As reported by Strabo (XV, 1, 62), when Alexander the Great was in Taxila, one of his companions named Aristobulus, noticed that in the city the dead were being fed to the vultures, a clear allusion to the presence of Zoroastrianism. The renowned University of Taxila became the greatest learning centre in the region, and allowed for exchanges between people from various cultures.
Several contemporaries, and close followers, of the Buddha are said to have studied in Achaemenid Taxila: King Pasenadi of Kosala, a close friend of the Buddha, Bandhula, the commander of Pasedani's army, Aṅgulimāla, a close follower of the Buddha, and Jivaka, court doctor at Rajagriha and personal doctor of the Buddha. According to Stephen Batchelor, the Buddha may have been influenced by the experiences and knowledge acquired by some of his closest followers in Taxila.
The 5th century BCE grammarian Pāṇini lived in an Achaemenid environment. He is said to have been born in the north-west, in Shalatula near Attock to the north-west of Taxila, in what was then a satrapy of the Achaemenid Empire following the Achaemenid conquest of the Indus Valley, which technically made him a Persian subject.
Kautilya, the influential Prime Minister of Chandragupta Maurya, is also said to have been a professor teaching in Taxila. According to Buddhist legend, Kautilya brought Chandragupta Maurya, the future founder of the Mauryan Empire to Taxila as a child, and had him educated there in "all the sciences and arts" of the period, including military sciences, for a period of 7 to 8 years. These legends match Plutarch's assertion that Alexander the Great met with the young Chandragupta while campaigning in the Punjab.
The Persians may have later participated, together with Sakas and Greeks, in the campaigns of Chandragupta Maurya to gain the throne of Magadha circa 320 BCE. The Mudrarakshasa states that after Alexander's death, an alliance of "Shaka-Yavana-Kamboja-Parasika-Bahlika" was used by Chandragupta Maurya in his campaign to take the throne in Magadha and found the Mauryan Empire. The Sakas were Scythians, the Yavanas were Greeks, and the Parasikas were Persians. David Brainard Spooner theorized upon Chandragupta Maurya's conquest and claimed that "it was with largely the Persian army that he won the throne of India."
Astronomical and astrological knowledge was also probably transmitted to India from Babylon during the 5th century BCE as a consequence of the Achaemenid presence in the sub-continent. Babylonian astronomy was the first form of astronomy to fully develop and likely influenced other civilizations. The spread of knowledge may have hastened with the expansion of the Achaemenid Empire.
According to David Pingree, elements of Achaemenid scientific knowledge, particularly works on omens and astronomy, were adopted by India from the 5th century BCE:
"India today is estimated to have about thirty million manuscripts, the largest body of handwritten reading material anywhere in the world. The literate culture of Indian science goes back to at least the fifth century B.C. ... as is shown by the elements of Mesopotamian omen literature and astronomy that entered India at that time."
Various Indian artefacts tend to suggest some Perso-Hellenistic artistic influence in India, mainly felt during the time of the Mauryan Empire. The sculpture of the Masarh lion, found near the Maurya capital of Pataliputra, raises the question of the Achaemenid and Greek influence on the art of the Maurya Empire, and on the western origins of stone carving in India. The lion is carved in Chunar sandstone, like the Pillars of Ashoka, and its finish is polished, a feature of the Maurya sculpture. According to S.P. Gupta, the sculptural style is unquestionably Achaemenid. This is particularly the case for the well-ordered tubular representation of whiskers (vibrissas) and the geometrical representation of inflated veins flush with the entire face. The mane, on the other hand, with tufts of hair represented in wavelets, is rather naturalistic. Very similar examples are however known in Greece and Persepolis. It is possible that this sculpture was made by an Achaemenid or Greek sculptor in India and either remained without effect, or was the Indian imitation of a Greek or Achaemenid model, somewhere between the fifth century B.C. and the first century B.C., although it is generally dated from the time of the Maurya Empire, around the 3rd century B.C.
The Pataliputra palace with its pillared hall shows decorative influences of the Achaemenid palaces and Persepolis and may have used the help of foreign craftsmen. Mauryan rulers may have even imported craftsmen from abroad to build royal monuments. This may be the result of the formative influence of craftsmen employed from Persia following the disintegration of the Achaemenid Empire after the conquests of Alexander the Great. The Pataliputra capital, or also the Hellenistic friezes of the Rampurva capitals, Sankissa, and the diamond throne of Bodh Gaya are other examples.
The renowned Mauryan polish, especially used in the Pillars of Ashoka, may also have been a technique imported from the Achaemenid Empire.

The similarity of the 4th century BCE Lycian barrel-vaulted tombs, such as the tomb of Payava, in the western part of the Achaemenid Empire, with the Indian architectural design of the Chaitya (starting at least a century later from circa 250 BCE, with the Lomas Rishi caves in the Barabar caves group), suggests that the designs of the Lycian rock-cut tombs travelled to India along the trade routes across the Achaemenid Empire.
Early on, James Fergusson, in his Illustrated Handbook of Architecture, while describing the very progressive evolution from wooden architecture to stone architecture in various ancient civilizations, has commented that "In India, the form and construction of the older Buddhist temples resemble so singularly these examples in Lycia". The structural similarities, down to many architectural details, with the Chaitya-type Indian Buddhist temple designs, such as the "same pointed form of roof, with a ridge", are further developed in The cave temples of India. The Lycian tombs, dated to the 4th century BCE, are either free-standing or rock-cut barrel-vaulted sarcophagi, placed on a high base, with architectural features carved in stone to imitate wooden structures. There are numerous rock-cut equivalents to the free-standing structures and decorated with reliefs. Fergusson went on to suggest an "Indian connection", and some form of cultural transfer across the Achaemenid Empire. The ancient transfer of Lycian designs for rock-cut monuments to India is considered as "quite probable".
Art historian David Napier has also proposed a reverse relationship, claiming that the Payava tomb was a descendant of an ancient South Asian style, and that Payava may actually have been a Graeco-Indian named "Pallava".

Regarding the Pillars of Ashoka, there has been much discussion of the extent of influence from Achaemenid Persia, since the column capitals supporting the roofs at Persepolis have similarities, and the "rather cold, hieratic style" of the Sarnath Lion Capital of Ashoka especially shows "obvious Achaemenid and Sargonid influence".
Hellenistic influence has also been suggested. In particular the abaci of some of the pillars (especially the Rampurva bull, the Sankissa elephant and the Allahabad pillar capital) use bands of motifs, like the bead and reel pattern, the ovolo, the flame palmettes, lotuses, which likely originated from Greek and Near-Eastern arts. Such examples can also be seen in the remains of the Mauryan capital city of Pataliputra.
The Aramaic language, official language of the Achaemenid Empire, started to be used in the Indian territories. Some of the Edicts of Ashoka in the north-western areas of Ashoka's territory, in modern Pakistan and Afghanistan, used Aramaic (the official language of the former Achaemenid Empire), together with Prakrit and Greek (the language of the neighbouring Greco-Bactrian kingdom and the Greek communities in Ashoka's realm).
The Indian Kharosthi script shows a clear dependency on the Aramaic alphabet but with extensive modifications to support the sounds found in Indic languages. One model is that the Aramaic script arrived with the Achaemenid Empire's conquest of the Indus River (modern Pakistan) in 500 BCE and evolved over the next 200+ years, reaching its final form by the 3rd century BCE where it appears in some of the Edicts of Ashoka.
The Edicts of Ashoka (circa 250 BCE) may show Achaemenid influences, including formulaic parallels with Achaemenid inscriptions, presence of Iranian loanwords (in Aramaic inscriptions), and the very act of engraving edicts on rocks and mountains (compare for example Behistun inscription). To describe his own edicts, Ashoka used the word Lipī (𑀮𑀺𑀧𑀺), now generally simply translated as "writing" or "inscription". It is thought the word "lipi", which is also orthographed "dipi" (𐨡𐨁𐨤𐨁) in the two Kharosthi versions of the rock edicts,[b] comes from an Old Persian prototype dipî (𐎮𐎡𐎱𐎡) also meaning "inscription", which is used for example by Darius I in his Behistun inscription,[c] suggesting borrowing and diffusion. There are other borrowings of Old Persian terms for writing-related words in the Edicts of Ashoka, such as nipista or nipesita (𐨣𐨁𐨤𐨁𐨯𐨿𐨟, "written" and "made to be written") in the Kharoshthi version of Major Rock Edict No.4, which can be related to the word nipištā (𐎴𐎡𐎱𐎡𐏁𐎫𐎠, "written") from the daiva inscription of Xerxes at Persepolis.
Several of the Edicts of Ashoka, such as the Kandahar Bilingual Rock Inscription or the Taxila inscription were written in Aramaic, one of the official languages of the former Achaemenid Empire.

Some relatively high quality terracotta statuettes have been recovered from the Mauryan Empire strata in the excavations of Mathura in northern India. Most of these terracottas show what appears to be female deities or mother goddesses. However, several figures of foreigners also appear in the terracottas from the 4th to the 2nd century BCE, which are either described simply as "foreigners" or Persian or Iranian because of their foreign features. These figurines might reflect the increased contacts of Indians with Iranian people during this period. Several of these seem to represent foreign soldiers who visited India during the Mauryan period and influenced modellers in Mathura with their peculiar ethnic features and uniforms. One of the terracotta statuettes, a man nicknamed the "Persian nobleman" and dated to the 2nd century BCE, can be seen wearing a coat, scarf, trousers and a turban.
S.P. Gupta also mentions the "male heads of foreigners from Patna city and Sarnath", which according to him attest to the presence of a foreign elite in the Gangetic plains during the Mauryan or late Mauryan period. This elite was West Asian, specifically related to the Pahlavas and Sakas based in Iran and Afghanistan, and their presence was a consequence of their eastern forays into India.
According to Ammianus Marcellinus, a 4th-century CE Roman author, Hystaspes, the father of Darius I, studied under the Brahmins in India, thus contributing to the development of the religion of the Magi (Zoroastrianism):
"Hystaspes, a very wise monarch, the father of Darius. Who while boldly penetrating into the remoter districts of upper India, came to a certain woody retreat, of which with its tranquil silence the Brahmans, men of sublime genius, were the possessors. From their teaching he learnt the principles of the motion of the world and of the stars, and the pure rites of sacrifice, as far as he could; and of what he learnt he infused some portion into the minds of the Magi, which they have handed down by tradition to later ages, each instructing his own children, and adding to it their own system of divination".— Ammianus Marcellinus, XXIII. 6.
In ancient sources, Hystapes is sometimes considered as identical with Vishtaspa (the Avestan and Old Persian name for Hystapes), an early patron of Zoroaster.
Historically, the life of the Buddha also coincided with the Achaemenid conquest of the Indus Valley. The Achaemenid occupation of the areas of Gandara and Hinduš, which was to last for about two centuries, was accompanied by Achaemenid religions, reformed Mazdaism or early Zoroastrianism, to which Buddhism might also have in part reacted. In particular, the ideas of the Buddha may have partly consisted in a rejection of the "absolutist" or "perfectionist" ideas contained in these Achaemenid religions.
Still, according to Christopher I. Beckwith, commenting on the content of the Edicts of Ashoka, the early Buddhist concepts of karma, rebirth, and affirming that good deeds will be rewarded in this life and the next, in Heaven, probably find their origin in Achaemenid Mazdaism, which had been introduced in India from the time of the Achaemenid conquest of Gandara.
Several satrapies were founded by the Achaemenid empire in the Indian subcontinent, including;
Other important satrapies in South Asia (in modern day's Balochistan) include;
