Indo-Greek Kingdoms

Background

Initial Greek presence in the Indian subcontinent

Greeks first began to establish authority in the Northwestern part of the Indian subcontinent during the time of the Persian Achaemenid Empire. Darius the Great conquered the area, but along with his successors also conquered much of the Greek world, which at the time included all of the western Anatolian peninsula. When Greek villages rebelled under the Persian yoke, they were sometimes ethnically cleansed, their inhabitants relocated to the far side of the empire around today's Afghanistan. Over time they grew influential politically and rose to power establishing their own independent kingdoms and expanding their realm in all directions.

In the fourth century BC, Alexander the Great defeated and conquered the Persian empire. In 326 BC, this included the northwestern part of the Indian subcontinent as far as the Hyphasis River. Alexander established satrapies and founded several cities, including Bucephala; he turned south when his troops refused to go further east. The Indian satrapies of the Punjab were left to the rule of Porus and Taxiles, who were confirmed again at the Treaty of Triparadisus in 321 BC, and the remaining Greek troops in these satrapies were left under the command of Alexander's general Eudemus. After 321 BC Eudemus toppled Taxiles, until he left India in 316 BC. To the south, another general also ruled over the Greek colonies of the Indus: Peithon, son of Agenor, until his departure for Babylon in 316 BC.

Around 322 BC, the Greeks (described as Yona or Yavana in Indian sources) may then have participated, together with other groups, in the uprising of Chandragupta Maurya against the Nanda dynasty, and gone as far as Pataliputra for the capture of the city from the Nandas. The Mudrarakshasa of Visakhadutta as well as the Jaina work Parisishtaparvan talk of Chandragupta's alliance with the Himalayan king Parvatka, often identified with Porus, and according to these accounts, this alliance gave Chandragupta a composite and powerful army made up of Yavanas (Greeks), Kambojas, Shakas (Scythians), Kiratas (Nepalese), Parasikas (Persians) and Bahlikas (Bactrians) who took Pataliputra.

In 305 BC, Seleucus I led an army to the Indus, where he encountered Chandragupta. The confrontation ended with a peace treaty, and "an intermarriage agreement" (Epigamia, Greek: Ἐπιγαμία), meaning either a dynastic marriage or an agreement for intermarriage between Indians and Greeks. Accordingly, Seleucus ceded his eastern territories to Chandragupta, possibly as far as Arachosia and received 500 war elephants (which played a key role in Seleucus's victory at the Battle of Ipsus):

Greek rule in Bactria

Alexander had also established several colonies in neighbouring Bactria, such as Alexandria on the Oxus (modern Ai-Khanoum) and Alexandria of the Caucasus (medieval Kapisa, modern Bagram). After Alexander's death in 323 BC, Bactria came under the control of Seleucus I Nicator, who founded the Seleucid Empire. The Greco-Bactrian Kingdom was founded when Diodotus I, the satrap of Bactria (and probably the surrounding provinces) seceded from the Seleucid Empire around 250 BC. The preserved ancient sources (see below) are somewhat contradictory and the exact date of Bactrian independence has not been settled. Somewhat simplified, there is a high chronology (c. 255 BC) and a low chronology (c. 246 BC) for Diodotos' secession. The high chronology has the advantage of explaining why the Seleucid king Antiochus II issued very few coins in Bactria, as Diodotos would have become independent there early in Antiochus' reign. On the other hand, the low chronology, from the mid-240s BC, has the advantage of connecting the secession of Diodotus I with the Third Syrian War, a catastrophic conflict for the Seleucid Empire.

Diodotus, the governor of the thousand cities of Bactria (Latin: Theodotus, mille urbium Bactrianarum praefectus), defected and proclaimed himself king; all the other people of the Orient followed his example and seceded from the Macedonians.

The new kingdom, highly urbanized and considered one of the richest of the Orient (opulentissimum illud mille urbium Bactrianum imperium "The extremely prosperous Bactrian empire of the thousand cities" Justin, XLI,1), was to further grow in power and engage into territorial expansion to the east and the west:

The Greeks who caused Bactria to revolt grew so powerful on account of the fertility of the country that they became masters, not only of Ariana, but also of India, as Apollodorus of Artemita says: and more tribes were subdued by them than by Alexander... Their cities were Bactra (also called Zariaspa, through which flows a river bearing the same name and emptying into the Oxus), and Darapsa, and several others. Among these was Eucratidia, which was named after its ruler.

When the ruler of neighbouring Parthia, the former satrap and self-proclaimed king Andragoras, was eliminated by Arsaces, the rise of the Parthian Empire cut off the Greco-Bactrians from direct contact with the Greek world. Overland trade continued at a reduced rate, while sea trade between Greek Egypt and Bactria developed.

Rise of the Shungas (185 BC)

In India, the Maurya dynasty was overthrown around 185 BC when Pushyamitra Shunga, the commander-in-chief of Mauryan Imperial forces and a Brahmin, assassinated the last of the Mauryan emperors Brihadratha. Pushyamitra Shunga then ascended the throne and established the Shunga Empire, which extended its control as far west as the Punjab.

Buddhist sources, such as the Ashokavadana, mention that Pushyamitra was hostile towards Buddhists and allegedly persecuted the Buddhist faith. A large number of Buddhist monasteries (viharas) were allegedly converted to Hindu temples, in such places as Nalanda, Bodhgaya, Sarnath or Mathura. While it is established by secular sources that Hinduism and Buddhism were in competition during this time, with the Shungas preferring the former to the latter, historians such as Etienne Lamotte and Romila Thapar argue that Buddhist accounts of persecution of Buddhists by Shungas are largely exaggerated. Some Puranic sources however also describe the resurgence of Brahmanism following the Maurya dynasty, and the killing of millions of Buddhists, such as the Pratisarga Parva of the Bhavishya Purana:

"At this time [after the rule of Chandragupta, Bindusara and Ashoka] the best of the brahmanas, Kanyakubja, performed sacrifice on the top of a mountain named Arbuda. By the influence of Vedic mantras, four Kshatriyas appeared from the yajna (sacrifice). (...) They kept Ashoka under their control and annihilated all the Buddhists. It is said there were 4 million Buddhists and all of them were killed by uncommon weapons".

History

Sources

Some narrative history has survived for most of the Hellenistic world, at least of the kings and the wars; this is lacking for India. The main Greco-Roman source on the Indo-Greeks is Justin, who wrote an anthology drawn from the Roman historian Pompeius Trogus, who in turn wrote, from Greek sources, at the time of Augustus Caesar. In addition to these dozen sentences, the geographer Strabo mentions India a few times in the course of his long dispute with Eratosthenes about the shape of Eurasia. Most of these are purely geographical claims, but he does mention that Eratosthenes' sources say that some of the Greek kings conquered further than Alexander; Strabo does not believe them on this, nor does he believe that Menander and Demetrius son of Euthydemus conquered more tribes than Alexander There is half a story about Menander in one of the books of Polybius which has not come down to us intact.

There are Indian literary sources, ranging from the Milinda Panha, a dialogue between a Buddhist sage Nagasena and Indianized names that may be related to Indo-Greek kings such as Menander I. Names in these sources are consistently Indianized, and there is some dispute whether, for example, Dharmamitra represents "Demetrius" or is an Indian prince with that name. There was also a Chinese expedition to Bactria by Chang-k'ien under the Emperor Wu of Han, recorded in the Records of the Grand Historian and Book of the Former Han, with additional evidence in the Book of the Later Han; the identification of places and peoples behind transcriptions into Chinese is difficult, and several alternate interpretations have been proposed.

Other evidence of the broader and longer influence of Indo-Greeks is possibly suggested by Yavanarajya inscription, dated to the 1st-century BC. It mentions Yavanas, a term which is derived from "Ionians", and which at that time most likely means "Indo-Greeks".

Expansion of Demetrius into India

Demetrius I, the son of Euthydemus is generally considered the Greco-Bactrian king who first launched the Greek expansion into India. He is therefore the founder of the Indo-Greek realm. The true intents of the Greek kings in occupying India are unknown, but it is thought that the elimination of the Maurya Empire by the Sunga greatly encouraged this expansion. The Indo-Greeks, in particular Menander I who is said in the Milindapanha to have converted to Buddhism, also possibly received the help of Indian Buddhists.

There is an inscription from his father's reign already officially hailing Demetrius as victorious. He also has one of the few absolute dates in Indo-Greek history: after his father held off Antiochus III for two years, 208–6 BC, the peace treaty included the offer of a marriage between Demetrius and Antiochus' daughter. Coins of Demetrius I have been found in Arachosia and in the Kabul Valley; the latter would be the first entry of the Greeks into India, as they defined it. There is also literary evidence for a campaign eastward against the Seres and the Phryni; but the order and dating of these conquests is uncertain.

Demetrius I seems to have conquered the Kabul valley, Arachosia and perhaps Gandhara; he struck no Indian coins, so either his conquests did not penetrate that far into India or he died before he could consolidate them. On his coins, Demetrius I always carries the elephant-helmet worn by Alexander, which seems to be a token of his Indian conquests. Bopearachchi believes that Demetrius received the title of "King of India" following his victories south of the Hindu Kush. He was also given, though perhaps only posthumously, the title Ἀνίκητος ("Aniketos", lit. Invincible) a cult title of Heracles, which Alexander had assumed; the later Indo-Greek kings Lysias, Philoxenus, and Artemidorus also took it. Finally, Demetrius may have been the founder of a newly discovered Yavana era, starting in 186/5 BC.

After the death of Demetrius, the Bactrian kings Pantaleon and Agathocles struck the first bilingual coins with Indian inscriptions found as far east as Taxila so in their time (c. 185–170 BC) the Bactrian kingdom seems to have included Gandhara. These first bilingual coins used the Brahmi script, whereas later kings would generally use Kharoshthi. They also went as far as incorporating Indian deities, variously interpreted as Hindu deities or the Buddha. They also included various Indian devices (lion, elephant, zebu bull) and symbols, some of them Buddhist such as the tree-in-railing. These symbols can also be seen in the Post-Mauryan coinage of Gandhara.

Rule of Menander I

The next important Indo-Greek king was Menander I who is considered to have been the most successful of the Indo-Greek kings, and who expanded the kingdom to its greatest extent by means of his various conquests. The finds of his coins are the most numerous and occur across the greatest geographical area, more than any of the other Indo-Greek kings. Coins stamped with Menander's likeness can be found as far away as Eastern Punjab over 600 miles distant. Menander seems to have begun a second wave of conquests, and it seems likely that the easternmost conquests were made by him.

Thus from 165 BCE until his death in 130 BCE, Menander I ruled Punjab with Sagala as his capital. Menander subsequently made an expedition across northern India to Mathura, where the Yavnarajya inscription was recorded. However, it is not known if this was a contiguous empire, or ruled through key city centers or polis. Soon after, Eucratides I king of the Greco-Bactrian Kingdom began warring with the Indo-Greeks in the north western frontier.

According to Apollodorus of Artemita, quoted by Strabo, the Indo-Greek territory for a while included the Indian coastal provinces of Sindh and possibly Gujarat. With archaeological methods, the Indo-Greek territory can however only be confirmed from the Kabul Valley to the eastern Punjab, so Greek presence outside was probably short-lived or non-existent.

Some sources also claim that the Indo-Greeks may have reached the Shunga capital Pataliputra in northern India. However, the nature of this expedition is a matter of controversy. The only recorded primary account regarding this campaign was written in the Yuga Purana, however this text was written as a forthcoming prophecy of an impending conflict. It is not known if the expedition was carried out, or if the Yavanas (Indo-Greeks) were successful in this campaign.

"After having conquered Saketa, the country of the Panchala and the Mathuras, the Yavanas, wicked and valiant, will reach Kusumadhvaja ("The town of the flower-standard", Pataliputra). The thick mud-fortifications at Pataliputra being reached, all the provinces will be in disorder, without doubt. Ultimately, a great battle will follow, with tree-like engines (siege engines)."

However the claim that the Yavanas held Pataliputra is not supported by numismatic or historical accounts, and is even contradicted by some inscriptions. King Kharavela of Kalinga, during his forth year reigning, was recorded in the Hathigumpha inscription to have routed a demoralized Indo-Greek army back to Mathura. It is not known which Indo-Greek was leading the army at the time, however it is presumed to be Menander I or perhaps even a later ruler. Then during his twelfth year in power, Kharavela is recorded to have battled the Shunga Empire and defeated the emperor Brhaspatimitra, known as Pushyamitra Shunga. Kharavela is then stated to have sacked the capital Pataliputra, and reclaimed the Jain idols and treasures that had been plundered from Kalinga and taken to Pataliputra. Based on the chronology and date during 1st century BC, it is postulated that Menander was the one leading the Indo-Greeks during Kharavela's reign.

Consolidation

Menander is considered to have been probably the most successful Indo-Greek king, and the conqueror of the largest territory. The finds of his coins are the most numerous and the most widespread of all the Indo-Greek kings. Menander is also remembered in Buddhist literature, where he is called Milinda, and is described in the Milinda Panha as a convert to Buddhism: he became an arhat whose relics were enshrined in a manner reminiscent of the Buddha. He also introduced a new coin type, with Athena Alkidemos ("Protector of the people") on the reverse, which was adopted by most of his successors in the East.

From the mid-2nd century BC, the Scythians, in turn being pushed forward by the Yuezhi who were completing a long migration from the border of China, started to invade Bactria from the north. Around 130 BC the last Greco-Bactrian king Heliocles was probably killed during the invasion and the Greco-Bactrian kingdom proper ceased to exist. The Parthians also probably played a role in the downfall of the Bactrian kingdom.

Immediately after the fall of Bactria, the bronze coins of Indo-Greek king Zoilos I (130–120 BC), successor of Menander in the western part of the Indian territories, combined the club of Herakles with a Scythian-type bowcase and short recurve bow inside a victory wreath, illustrating interaction with horse-mounted people originating from the steppes, possibly either the Scythians (future Indo-Scythians), or the Yuezhi (future Kushans) who had invaded Greco-Bactria. This bow can be contrasted to the traditional Hellenistic long bow depicted on the coins of the eastern Indo-Greek queen Agathokleia. It is now known that 50 years later, the Indo-Scythian Maues was in alliance with the Indo-Greek kings in Taxila, and one of those kings, Artemidoros seems to claim on his coins that he is the son of Maues, although this is now disputed.

The extent of Indo-Greek rule is still uncertain and disputed. Probable members of the dynasty of Menander include the ruling queen Agathokleia, her son Strato I, and Nicias, though it is uncertain whether they ruled directly after Menander.

Other kings emerged, usually in the western part of the Indo-Greek realm, such as Zoilos I, Lysias, Antialcidas and Philoxenus. These rulers may have been relatives of either the Eucratid or the Euthydemid dynasties. The names of later kings were often new (members of Hellenistic dynasties usually inherited family names) but old reverses and titles were frequently repeated by the later rulers.

Interactions with Indian culture and religions

Vidisha

It is around this time, in 115 BC, that the embassy of Heliodorus, from king Antialkidas to the court of the Sungas king Bhagabhadra in Vidisha, is recorded. In the Sunga capital, Heliodorus established the Heliodorus pillar in a dedication to Vāsudeva. This would indicate that relations between the Indo-Greeks and the Sungas had improved by that time, that people traveled between the two realms, and also that the Indo-Greeks readily followed Indian religions.

Sanchi

Also around the same period, circa 115 BC, decorative reliefs were introduced for the first time at nearby Sanchi, 6 km away from Vidisha, by craftsmen from the northwest. These craftsmen left mason's marks in Kharoshthi, mainly used in the area around Gandhara, as opposed to the local Brahmi script. This seems to imply that these foreign workers were responsible for some of the earliest motifs and figures that can be found on the railings of the stupa. These early reliefs at Sanchi, (those of Sanchi Stupa No.2), are dated to 115 BC, while the more extensive pillar carvings are dated to 80 BC. These reliefs have been described as "the oldest extensive stupa decoration in existence". They are considered the origin of Jataka illustrations in India.

A warrior figure, the Bharhut Yavana, appeared prominently on a high relief on the railings of the stupa of Bharhut circa 100 BC. The warrior has the flowing head band of a Greek king, a northern tunic with Hellenistic pleats, he hold a grape in his hand, and has a Buddhist triratana symbol on his sword. He has the role of a dvarapala, a Guardian of the entrance of the Stupa. The warrior has been described as a Greek, Some have suggested that he might even represent king Menander.

Also around that time, craftsmen from the Gandhara area are known to have been involved in the construction of the Buddhist torana gateways at Bharhut, which are dated to 100–75 BC: this is because mason's marks in Kharosthi have been found on several elements of the Bharhut remains, indicating that some of the builders at least came from the north, particularly from Gandhara where the Kharoshti script was in use.

Cunningham explained that the Kharosthi letters were found on the balusters between the architraves of the gateway, but none on the railings which all had Indian markings, summarizing that the gateways, which are artistically more refined, must have been made by artists from the North, whereas the railings were made by local artists.

Decline

King Philoxenus (100–95 BC) briefly occupied the whole Greek territory from the Paropamisadae to Western Punjab, after that the territories fragmented again between smaller Indo-Greek kings. Throughout the 1st century BC, the Indo-Greeks progressively lost ground to the Indians in the east, and the Scythians, the Yuezhi, and the Parthians in the West. About 20 Indo-Greek kings are known during this period, down to the last known Indo-Greek rulers, Strato II and Strato III, who ruled in the Punjab region until around 10 AD.

Around eight "western" Indo-Greek kings are known; most of them are distinguished by their issues of Attic coins for circulation in the neighbouring region.

One of the last important kings in the Paropamisadae (part of the Hindu Kush) was Hermaeus, who ruled until around 80 BC; soon after his death the Yuezhi or Sakas took over his areas from neighbouring Bactria. When Hermaeus is depicted on his coins riding a horse, he is equipped with the recurve bow and bow-case of the steppes and RC Senior believes him to be of partly nomad origin. The later king Hippostratus may however also have held territories in the Paropamisadae.

After the death of Hermaeus, the Yuezhi or Saka nomads became the new rulers of the Paropamisadae, and minted vast quantities of posthumous issues of Hermaeus up to around 40 AD, when they blend with the coinage of the Kushan king Kujula Kadphises. The first documented Yuezhi prince, Sapadbizes, ruled around 20 BC, and minted in Greek and in the same style as the western Indo-Greek kings, probably depending on Greek mints and chelators.

Around 80 BC, an Indo-Scythian king named Maues, possibly a general in the service of the Indo-Greeks, ruled for a few years in northwestern India before the Indo-Greeks again took control. He seems to have been married to an Indo-Greek princess named Machene. King Hippostratus (65–55 BC) seems to have been one of the most successful subsequent Indo-Greek kings until he lost to the Indo-Scythian Azes I, who established an Indo-Scythian dynasty in 48/47 BC. Various coins seem to suggest that some sort of alliance may have taken place between the Indo-Greeks and the Scythians.

Although the Indo-Scythians clearly ruled militarily and politically, they remained surprisingly respectful of Greek and Indian cultures. Their coins were minted in Greek mints, continued using proper Greek and Kharoshthi legends, and incorporated depictions of Greek deities, particularly Zeus. The Mathura lion capital inscription attests that they adopted the Buddhist faith, as do the depictions of deities forming the vitarka mudra on their coins. Greek communities, far from being exterminated, probably persisted under Indo-Scythian rule. There is a possibility that a fusion, rather than a confrontation, occurred between the Greeks and the Indo-Scythians: in a recently published coin, Artemidorus seems to present himself as "son of Maues" (but this is now disputed), and the Buner reliefs show Indo-Greeks and Indo-Scythians reveling in a Buddhist context.

Later contributions

Some Greek nuclei may have continued to survive until the 2nd century AD.

Nahapana had at his court a Greek writer named Yavanesvara ("Lord of the Greeks"), who translated from Greek to Sanskrit the Yavanajataka ("Saying of the Greeks"), an astrological treatise and India's earliest Sanskrit work in horoscopy.

A large number of Buddhist caves in India, particularly in the west of the country, were artistically hewn between the 1st century BC and the 2nd century AD. Numerous donors provided the funds for the building of these caves and left donatory inscriptions, including laity, members of the clergy, government officials. Foreigners, mostly self-declared Yavanas, represented about 8% of all inscriptions.

Karla Caves

Yavanas from the region of Nashik are mentioned as donors for six structural pillars in the Great Buddhist Chaitya of the Karla Caves built and dedicated by Western Satraps ruler Nahapana in 120 AD, although they seem to have adopted Buddhist names. In total, the Yavanas account for nearly half of the known dedicatory inscriptions on the pillars of the Great Chaitya. To this day, Nasik is known as the wine capital of India, using grapes that were probably originally imported by the Greeks.

Shivneri Caves

Two more Buddhist inscriptions by Yavanas were found in the Shivneri Caves. One of the inscriptions mentions the donation of a tank by the Yavana named Irila, while the other mentions the gift of a refectory to the Sangha by the Yavana named Cita. On this second inscription, the Buddhist symbols of the triratna and of the swastika (reversed) are positioned on both sides of the first word "Yavana(sa)".

Pandavleni Caves

One of the Buddhist caves (Cave No.17) in the Pandavleni Caves complex near Nashik was built and dedicated by "Indragnidatta the son of the Yavana Dharmadeva, a northerner from Dattamittri", in the 2nd century AD. The city of "Dattamittri" is thought to be the city of Demetrias in Arachosia, mentioned by Isidore of Charax.

Ideology

Buddhism flourished under the Indo-Greek kings, and their rule, especially that of Menander, has been remembered as benevolent. It has been suggested, although direct evidence is lacking, that their invasion of India was intended to show their support for the Mauryan empire with which they may have had a long history of marital alliances, exchange of presents, demonstrations of friendship, exchange of ambassadors and religious missions. The historian Diodorus even wrote that the king of Pataliputra had "great love for the Greeks".

The Greek expansion into Indian territory may have been intended to protect Greek populations in India, and to protect the Buddhist faith from the religious persecutions of the Shungas. The city of Sirkap founded by Demetrius combines Greek and Indian influences without signs of segregation between the two cultures.

The first Greek coins to be minted in India, those of Menander I and Apollodotus I bear the mention "Saviour king" (ΒΑΣΙΛΕΩΣ ΣΩΤΗΡΟΣ), a title with high value in the Greek world which indicated an important deflective victory. For instance, Ptolemy I had been Soter (saviour) because he had helped save Rhodes from Demetrius the Besieger, and Antiochus I because he had saved Asia Minor from the Gauls. The title was also inscribed in Pali as ("Tratarasa") on the reverse of their coins. Menander and Apollodotus may indeed have been saviours to the Greek populations residing in India, and to some of the Indians as well.

Also, most of the coins of the Greek kings in India were bilingual, written in Greek on the front and in Pali on the back (in the Kharosthi script, derived from Aramaic, rather than the more eastern Brahmi, which was used only once on coins of Agathocles of Bactria), a tremendous concession to another culture never before made in the Hellenic world. From the reign of Apollodotus II, around 80 BC, Kharosthi letters started to be used as mintmarks on coins in combination with Greek monograms and mintmarks, suggesting the participation of local technicians to the minting process. Incidentally, these bilingual coins of the Indo-Greeks were the key in the decipherment of the Kharoshthi script by James Prinsep (1835) and Carl Ludwig Grotefend (1836). Kharoshthi became extinct around the 3rd century AD.

In Indian literature, the Indo-Greeks are described as Yavanas (in Sanskrit), or Yonas (in Pali) both thought to be transliterations of "Ionians". In the Harivamsa the "Yavana" Indo-Greeks are qualified, together with the Sakas, Kambojas, Pahlavas and Paradas as Kshatriya-pungava i.e. foremost among the Warrior caste, or Kshatriyas. The Majjhima Nikaya explains that in the lands of the Yavanas and Kambojas, in contrast with the numerous Indian castes, there were only two classes of people, Aryas and Dasas (masters and slaves).

Religion

In addition to the worship of the Classical pantheon of the Greek deities found on their coins (Zeus, Herakles, Athena, Apollo...), the Indo-Greeks were involved with local faiths, particularly with Buddhism, but also with Hinduism and Zoroastrianism.

Interactions with Buddhism

Chandragupta Maurya, the founder of the Mauryan Empire, conquered the Greek satraps left by Alexander, which belonged to Seleucus I Nicator of the Seleucid Empire. The Mauryan Emperor Ashoka would then establish the largest empire in the Indian Subcontinent through an aggressive expansion. Ashoka converted to Buddhism following the destructive Kalinga War, abandoning further conquests in favor of humanitarian reforms. Ashoka erected the Edicts of Ashoka to spread Buddhism and the 'Law of Piety' throughout his dominion. In one of his edicts, Ashoka claims to have converted his Greek population along with others to Buddhism.

Here in the king's domain among the Greeks, the Kambojas, the Nabhakas, the Nabhapamkits, the Bhojas, the Pitinikas, the Andhras and the Palidas, everywhere people are following Beloved-of-the-Gods' instructions in Dharma.

The last Mauryan Emperor Brihadratha was assassinated by Pushyamitra Shunga, the former senapati or "army lord" of the Mauryan Empire and founder of the Shunga Empire. Pushyamitra is alleged to have persecuted Buddhism in favor of Hinduism, likely in attempt to further remove the legacy of the Mauryan Empire.

... Pushyamitra equipped a fourfold army, and intending to destroy the Buddhist religion, he went to the Kukkutarama (in Pataliputra). ... Pushyamitra therefore destroyed the sangharama, killed the monks there, and departed. ... After some time, he arrived in Sakala, and proclaimed that he would give a ... reward to whoever brought him the head of a Buddhist monk.

It is possible that Menander I Soter or the "Saviour king", choose Sakala as his capital due to the Buddhist presence there. Menander I, is stated to have converted to Buddhism in the Milinda Panha, which records the dialogue between Menander and the Buddhist monk Nagasena. Menander is claimed to have obtained the title of an arhat.And afterwards, taking delight in the wisdom of the Elder, he (Menander) handed over his kingdom to his son, and abandoning the household life for the house-less state, grew great in insight, and himself attained to Arahatship!

The wheel he represented on some of his coins was most likely Buddhist Dharmachakra,.

"Followers of the Dharma"

Several Indo-Greek kings use the title "Dharmikasa", i.e. "Follower of the Dharma", in the Kharoshti script on the obverse of their coins. The corresponding legend in Greek is "Dikaios" ("The Just"), a rather usual attribute on Greek coins. The expression "Follower of the Dharma" would of course resonate strongly with Indian subjects, used to this expression being employed by pious kings, especially since the time of Ashoka who advocated the Dharma in his inscriptions. The seven kings using "Dharmakasa", i.e. "Follower of the Dharma", are late Indo-Greek kings, from around 150 BC, right after the reign of Menander I, and mainly associated with the area of Gandhara: Zoilos I (130–120 BC), Strato (130–110 BC), Heliokles II (95–80 BC), Theophilos (130 or 90 BC), Menander II (90–85 BC), Archebios (90–80 BC) and Peukolaos (c. 90 BC). The attribute of Dharmika was again used a century later by a known Buddhist practitioner, Indo-Scythian king Kharahostes, to extoll on his coins the virtues of his predecessor king Azes.

Blessing gestures

From the time of Agathokleia and Strato I, circa 100 BC, kings and divinities are regularly show on coins making blessing gestures, which often seem similar to the Buddhist Vitarka mudra. As centuries passed, the exact shapes taken by the hand becomes less clear. This blessing gesture was also often adopted by the Indo-Scythians.

Vaishnavites

The Heliodorus pillar is a stone column that was erected around 113 BC in central India in Vidisha near modern Besnagar, by Heliodorus, a Greek ambassador of the Indo-Greek king Antialcidas to the court of the Shunga king Bhagabhadra. The pillar originally supported a statue of Garuda. In the dedication, the Indo-Greek ambassador explains he is a devotee of "Vāsudeva, the God of Gods". Historically, it is the first known inscription related to the Bhagavata group in India.

Art

In general, the art of the Indo-Greeks is poorly documented, and few works of art (apart from their coins and a few stone palettes) are directly attributed to them. The coinage of the Indo-Greeks however is generally considered some of the most artistically brilliant of Antiquity. The Hellenistic heritage (Ai-Khanoum) and artistic proficiency of the Indo-Greek world would suggest a rich sculptural tradition as well, but traditionally very few sculptural remains have been attributed to them. On the contrary, most Gandharan Hellenistic works of art are usually attributed to the direct successors of the Indo-Greeks in India in the 1st century AD, such as the nomadic Indo-Scythians, the Indo-Parthians and, in an already decadent state, the Kushans In general, Gandharan sculpture cannot be dated exactly, leaving the exact chronology open to interpretation.

The possibility of a direct connection between the Indo-Greeks and Greco-Buddhist art has been reaffirmed recently as the dating of the rule of Indo-Greek kings has been extended to the first decades of the 1st century AD, with the reign of Strato II in the Punjab. Also, Foucher, Tarn, and more recently, Boardman, Bussagli and McEvilley have taken the view that some of the most purely Hellenistic works of northwestern India and Afghanistan, may actually be wrongly attributed to later centuries, and instead belong to a period one or two centuries earlier, to the time of the Indo-Greeks in the 2nd–1st century BC:

This is particularly the case of some purely Hellenistic works in Hadda, Afghanistan, an area which "might indeed be the cradle of incipient Buddhist sculpture in Indo-Greek style". Referring to one of the Buddha triads in Hadda, in which the Buddha is sided by very Classical depictions of Herakles/Vajrapani and Tyche/Hariti, Boardman explains that both figures "might at first (and even second) glance, pass as, say, from Asia Minor or Syria of the first or second century BC (...) these are essentially Greek figures, executed by artists fully conversant with far more than the externals of the Classical style".

Alternatively, it has been suggested that these works of art may have been executed by itinerant Greek artists during the time of maritime contacts with the West from the 1st to the 3rd century AD.

The Greco-Buddhist art of Gandhara, beyond the omnipresence of Greek style and stylistic elements which might be simply considered an enduring artistic tradition, offers numerous depictions of people in Greek Classical realistic style, attitudes and fashion (clothes such as the chiton and the himation, similar in form and style to the 2nd century BC Greco-Bactrian statues of Ai-Khanoum, hairstyle), holding contraptions which are characteristic of Greek culture (amphoras, "kantaros" Greek drinking cups), in situations which can range from festive (such as Bacchanalian scenes) to Buddhist-devotional.

Economy

Very little is known about the economy of the Indo-Greeks, although it seems to have been rather vibrant.

Coinage

The abundance of their coins would tend to suggest large mining operations, particularly in the mountainous area of the Hindu-Kush, and an important monetary economy. The Indo-Greek did strike bilingual coins both in the Greek "round" standard and in the Indian "square" standard, suggesting that monetary circulation extended to all parts of society. The adoption of Indo-Greek monetary conventions by neighbouring kingdoms, such as the Kunindas to the east and the Satavahanas to the south, would also suggest that Indo-Greek coins were used extensively for cross-border trade.

Tribute payments

It would also seem that some of the coins emitted by the Indo-Greek kings, particularly those in the monolingual Attic standard, may have been used to pay some form of tribute to the Yuezhi tribes north of the Hindu-Kush. This is indicated by the coins finds of the Qunduz hoard in northern Afghanistan, which have yielded quantities of Indo-Greek coins in the Hellenistic standard (Greek weights, Greek language), although none of the kings represented in the hoard are known to have ruled so far north. Conversely, none of these coins have ever been found south of the Hindu-Kush.

Trade with China

The Indo-Greek kings in Southern Asia issued the first known cupro-nickel coins, with Euthydemus II, dating from 180 to 170 BC, and his younger brothers Pantaleon and Agathocles around 170 BC. As only China was able to produce cupro-nickel at that time, and as the alloy ratios are exclusively similar, it has been suggested that the metal was the result of exchanges between China and Bactria.

An indirect testimony by the Chinese explorer Zhang Qian, who visited Bactria around 128 BC, suggests that intense trade with Southern China was going through northern India. Zhang Qian explains that he found Chinese products in the Bactrian markets, and that they were transiting through northwestern India, which he incidentally describes as a civilization similar to that of Bactria:

"When I was in Bactria", Zhang Qian reported, "I saw bamboo canes from Qiong and cloth (silk?) made in the province of Shu. When I asked the people how they had gotten such articles, they replied: "Our merchants go buy them in the markets of Shendu (northwestern India). Shendu, they told me, lies several thousand li southeast of Bactria. The people cultivate land, and live much like the people of Bactria".

Recent excavations at the burial site of China's first Emperor Qin Shi Huang, dating back to the 3rd century BCE, also suggest Greek influence in the artworks found there, including in the manufacture of the famous Terracotta Army. It is also suggested that Greek artists may have come to China at that time to train local artisans in making sculptures.

Indian Ocean trade

Maritime relations across the Indian Ocean started in the 3rd century BC, and further developed during the time of the Indo-Greeks together with their territorial expansion along the western coast of India. The first contacts started when the Ptolemies constructed the Red Sea ports of Myos Hormos and Berenike, with destination the Indus delta, the Kathiawar peninsula or Muziris. Around 130 BC, Eudoxus of Cyzicus is reported (Strabo, Geog. II.3.4) to have made a successful voyage to India and returned with a cargo of perfumes and gemstones. By the time Indo-Greek rule was ending, up to 120 ships were setting sail every year from Myos Hormos to India (Strabo Geog. II.5.12).

Armed forces

The coins of the Indo-Greeks provide rich clues on their uniforms and weapons. Typical Hellenistic uniforms are depicted, with helmets being either round in the Greco-Bactrian style, or the flat kausia of the Macedonians (coins of Apollodotus I).

Military technology

Their weapons were spears, swords, longbow (on the coins of Agathokleia) and arrows. Around 130 BC, the Central Asian recurve bow of the steppes with its gorytos box started to appear for the first time on the coins of Zoilos I, suggesting strong interactions (and apparently an alliance) with nomadic peoples, either the Yuezhi or the Scythians. The recurve bow becomes a standard feature of Indo-Greek horsemen by 90 BC, as seen on some of the coins of Hermaeus.

Generally, Indo-Greek kings are often represented riding horses, as early as the reign of Antimachus II around 160 BC. The equestrian tradition probably goes back to the Greco-Bactrians, who are said by Polybius to have faced a Seleucid invasion in 210 BC with 10,000 horsemen. Although war elephants are never represented on coins, a harness plate (phalera) dated to the 3rd–2nd century BC, today in the Hermitage Museum, depicts a helmetted Greek combatant on an Indian war elephant.

The Milinda Panha, in the questions of Nagasena to king Menander, provides a rare glimpse of the military methods of the period:

The Milinda Panha also describes the structure of Menander's army:

Now one day Milinda the king proceeded forth out of the city to pass in review the innumerable host of his mighty army in its fourfold array (of elephants, cavalry, bowmen, and soldiers on foot).

Size of Indo-Greek armies

The armed forces of the Indo-Greeks engaged in battles with other Indian kingdoms. The ruler of Kalinga, King Kharavela, states in the Hathigumpha inscription that during the 8th year of his reign he led a large army in the direction of a Yavana King, and that he forced their demoralized army to retreat to Mathura."Then in the eighth year, (Kharavela) with a large army having sacked Goradhagiri causes pressure on Rajagaha (Rajagriha). On account of the loud report of this act of valour, the Yavana (Greek) King Dimi[ta] retreated to Mathura having extricated his demoralized army."

The name of the Yavana king is not clear, but it contains three letters, and the middle letter can be read as ma or mi. R. D. Banerji and K.P. Jayaswal read the name of the Yavana king as "Dimita", and identify him with Demetrius I of Bactria. However, according to Ramaprasad Chanda, this identification results in "chronological impossibilities".

The Greek ambassador Megasthenes took special note of the military strength of Kalinga in his Indica in the middle of the 3rd century BC:

The royal city of the Calingae (Kalinga) is called Parthalis. Over their king 60,000 foot-soldiers, 1,000 horsemen, 700 elephants keep watch and ward in "procinct of war."

An account by the Roman writer Justin gives another hint of the size of Indo-Greek armies, which, in the case of the conflict between the Greco-Bactrian Eucratides and the Indo-Greek Demetrius II, he numbers at 60,000 (although they allegedly lost to 300 Greco-Bactrians):

Eucratides led many wars with great courage, and, while weakened by them, was put under siege by Demetrius, king of the Indians. He made numerous sorties, and managed to vanquish 60,000 enemies with 300 soldiers, and thus liberated after four months, he put India under his rule

The Indo-Greek armies would be conquered by Indo-Scythians, a nomadic tribe from Central Asia.

Legacy

From the 1st century AD, the Greek communities of central Asia and the northwestern Indian subcontinent lived under the control of the Kushan branch of the Yuezhi, apart from a short-lived invasion of the Indo-Parthian Kingdom. The Kushans founded the Kushan Empire, which was to prosper for several centuries. In the south, the Greeks were under the rule of the Western Kshatrapas. The Kalash tribe of the Chitral Valley claim to be descendants of the Indo-Greeks; although this is disputed.

It is unclear how much longer the Greeks managed to maintain a distinct presence in the Indian sub-continent. The legacy of the Indo-Greeks was felt however for several centuries, from the usage of the Greek language and calendrical methods, to the influences on the numismatics of the Indian subcontinent, traceable down to the period of the Gupta Empire in the 4th century.

The Greeks may also have maintained a presence in their cities until quite late. Isidorus of Charax in his 1st century AD "Parthian stations" itinerary described an "Alexandropolis, the metropolis of Arachosia", thought to be Alexandria Arachosia, which he said was still Greek even at such a late time:

Beyond is Arachosia. And the Parthians call this White India; there are the city of Biyt and the city of Pharsana and the city of Chorochoad and the city of Demetrias; then Alexandropolis, the metropolis of Arachosia; it is Greek, and by it flows the river Arachotus. As far as this place the land is under the rule of the Parthians.

The Indo-Greeks may also have had some influence on the religious plane as well, especially in relation to the developing Mahayana Buddhism. Mahayana Buddhism has been described as "the form of Buddhism which (regardless of how Hinduized its later forms became) seems to have originated in the Greco-Buddhist communities of India, through a conflation of the Greek Democritean–Sophistic–Pyrrhonist tradition with the rudimentary and unformalized empirical and skeptical elements already present in early Buddhism".

Chronology

Today 36 Indo-Greek kings are known. Several of them are also recorded in Western and Indian historical sources, but the majority are known through numismatic evidence only. The exact chronology and sequencing of their rule is still a matter of scholarly inquiry, with adjustments regular being made with new analysis and coin finds (overstrikes of one king over another's coins being the most critical element in establishing chronological sequences).

There is an important evolution of coin shape (round to square) and material (from gold to silver to brass) across the territories and the periods, and from Greek type to Indian type over a period of nearly 3 centuries. Also, the quality of coinage illustration decreases down to the 1st century AD. Coinage evolution is an important point of Indo-Greek history, and actually one of the most important since most of these kings are only known by their coins, and their chronology is mainly established by the evolution of the coin types.
