History of the Indo Greek Kingdom

Greco-Roman sources

The Greco-Bactrians went over the Hindu Kush and also started to re-occupy the area of Arachosia, where Greek populations had been living since before the acquisition of the territory by Chandragupta from Seleucus. Isidore of Charax describes Greek cities there, one of them called Demetrias, probably in honour of the conqueror Demetrius.

According to Strabo, Greek advances temporarily went as far as the Shunga capital Pataliputra (today Patna) in eastern India:

"Of the eastern parts of India, then, there have become known to us all those parts which lie this side of the Hypanis, and also any parts beyond the Hypanis of which an account has been added by those who, after Alexander, advanced beyond the Hypanis, to the Ganges and Pataliputra."

The 1st century BCE Greek historian Apollodorus, quoted by Strabo, affirms that the Bactrian Greeks, led by Demetrius I and Menander, conquered India and occupied a larger territory than the Greeks under Alexander the Great, going beyond the Hypanis towards the Himalayas:

"The Greeks became masters of India and more tribes were subdued by them than by Alexander—by Menander in particular, for some were subdued by him personally and others by Demetrius, the son of Euthydemus the king of the Bactrians."

The Roman historian Justin also mentioned the Indo-Greek kingdom, describing a "Demetrius,King of the Indians" ("Regis Indorum"), and explaining that after vanquishing him Eucratides in turn "put India under his rule" ("Indiam in potestatem redegit") (since the time of the embassies of Megasthenes in the 3rd century BCE "India" was understood as the entire subcontinent, and was cartographed by geographers such as Eratosthenes). Justin also mentions Apollodotus and Menander as kings of the Indians.

Greek and Indian sources tend to indicate that the Greeks campaigned as far as Pataliputra until they were forced to retreat. This advance probably took place under the reign of Menander, the most important Indo-Greek king (A.K. Narain and Keay 2000) and was likely only of a military advance of temporary nature, perhaps in alliance with native Indian states. The permanent Indo-Greek dominions extended only from the Kabul Valley to the eastern Punjab or slightly further east.

To the south, the Greeks occupied the areas of the Sindh and Gujarat down to the region of Surat (Greek: Saraostus) near Mumbai (Bombay), including the strategic harbour of Barigaza (Bharuch), as attested by several writers (Strabo 11; Periplus of the Erythraean Sea, Chap. 41/47) and as evidenced by coins dating from the Indo-Greek ruler Apollodotus I:

"The Greeks... took possession, not only of Patalena, but also, on the rest of the coast, of what is called the kingdom of Saraostus and Sigerdis."

The 1st century CE Periplus of the Erythraean Sea describes numerous Greek buildings and fortifications in Barigaza, although mistakenly attributing them to Alexander, and testifies to the circulation of Indo-Greek coinage in the region:

"The metropolis of this country is Minnagara, from which much cotton cloth is brought down to Barygaza. In these places there remain even to the present time signs of the expedition of Alexander, such as ancient shrines, walls of forts and great wells."

"To the present day ancient drachmae are current in Barygaza, coming from this country, bearing inscriptions in Greek letters, and the devices of those who reigned after Alexander, Apollodorus (sic) and Menander."

From ancient authors (Pliny, Arrian, Ptolemy and Strabo), a list of provinces, satrapies, or simple regional designations, and Greek cities from within the Indo-Greek Kingdom can be discerned (though others have been lost), ranging from the Indus basin to the upper valley of the Ganges.

Indian sources

Various Indian records describe Yavana attacks on Mathura, Panchala, Saketa, and Pataliputra. The term Yavana is thought to be a transliteration of "Ionians" and is known to have designated Hellenistic Greeks (starting with the Edicts of Ashoka, where Ashoka writes about "the Yavana king Antiochus"), but may have sometimes referred to other foreigners as well, especially in later centuries.

Patanjali, a grammarian and commentator on Pāṇini around 150 BCE, describes in the Mahābhāsya, the invasion in two examples using the imperfect tense of Sanskrit, denoting a recent event:

The Anushasanaparava of the Mahabharata affirms that the country of Mathura, the heartland of India, was under the joint control of the Yavanas and the Kambojas. The Vayupurana asserts that Mathura was ruled by seven Greek kings over a period of 82 years.

Accounts of battles between the Greeks and the Shunga in Central India are also found in the Mālavikāgnimitram, a play by Kālidāsa which describes an encounter between Greek forces and Vasumitra, the grandson of Pushyamitra, during the latter's reign.

Also the Brahmanical text of the Yuga Purana, which describes Indian historical events in the form of a prophecy, relates the attack of the Indo-Greeks on the capital Pataliputra, a magnificent fortified city with 570 towers and 64 gates according to Megasthenes, and describes the ultimate destruction of the city's walls:

"Then, after having approached Saketa together with the Panchalas and the Mathuras, the Yavanas, valiant in battle, will reach Kusumadhvaja ("The town of the flower-standard", Pataliputra). Then, once Puspapura (another name of Pataliputra) has been reached and its celebrated mud[-walls] cast down, all the realm will be in disorder."

According to the Yuga Purana a situation of complete social disorder follows, in which the Yavanas rule and mingle with the people, and the position of the Brahmins and the Sudras is inverted:

"Sudras will also be utterers of bho (a form of address used towards an equal or inferior), and Brahmins will be utterers of arya (a form of address used towards a superior), and the elders, most fearful of dharma, will fearlessly exploit the people. And in the city the Yavanas, the princes, will make this people acquainted with them: but the Yavanas, infatuated by war, will not remain in Madhyadesa."

Epigraphic remains

Several depictions of Greeks in Central India dated to the 2nd-1st century BCE are known, such as the Greek soldier in Bharhut, or a frieze in Sanchi which describes Greek-looking foreigners honouring the Sanchi stupa with gifts, prayers and music (image above). They wear the chlamys cape over short chiton tunics without trousers, and have high-laced sandals. They are beardless with short curly hair and headbands, and two men wear the conical pilos hat. They play various instruments, including two carnyxes, and one aulos double-flute. This is near Vidisa, where an Indo-Greek monument, the Heliodorus pillar, is known.

A pillar discovered in Reh, in the Ganges valley 350 km south-east of Mathura mentions Menander:

"The great king of kings, the great king Menander, saviour, steadfast in the Law (dharma), victorious and unvanquished..."

Another inscription 17mk from Mathura, the Maghera inscription, contains the phrase "In the 116th year of the Greek kings...", suggesting Greek rule in the area until around 70 BCE, as the "Greek era" is thought to have started around 186 BCE.

Urban remains

The city of Sirkap, today in northwestern Pakistan near Taxila, was built according to the "Hippodamian" grid-plan characteristic of Greek cities, and was a Hellenistic fortress of considerable proportions, with a 6,000 meter wall on the circumference, of a height of about 10 meters. The houses of the Indo-Greek level are "the best planned of all the six strata, and the rubble masonry of which its walls are built is also the most solid and compact". It is thought that the city was built by Demetrius.

Artifacts

Several Hellenistic artifacts have been found, in particular coins of Indo-Greek kings, stone palettes representing Greek mythological scenes, and small statuettes. Some of them are purely Hellenistic, others indicate an evolution of the Greco-Bactrian styles found at Ai-Khanoum towards more indianized styles. For example, accessories such as Indian ankle bracelets can be found on some representations of Greek mythological figures such as Artemis.

The excavations of the Greek levels at Sirkap were however very limited and made in peripheral areas, out of respect for the more recent archeological strata (those of the Indo-Scythian and especially Indo-Parthian levels) and the remaining religious buildings, and due to the difficulty of excavating extensively to a depth of about 6 meters. The results, although interesting, are partial and cannot be considered as exhaustive. Beyond this, no extensive archaeological excavation of an Indo-Greek city has ever essentially been done.

Quantities of Hellenistic artifacts and ceramics can also be found throughout Northern India. Clay seals depicting Greek deities, and the depiction of an Indo-Greek king thought to be Demetrius were found at Benares.

Stupas

When the Indo-Greeks settled in the area of Taxila, large Buddhist structures were already present, such as the stupa of Dharmarajika built by Ashoka in the 3rd century BCE. These structures were reinforced in the following centuries, by building rings of smaller stupas and constructions around the original ones. Numerous coins of the Indo-Greek king Zoilos II were found under the foundation of a 1st-century BCE rectangular chapel near the Dharmarajika stupa.

Also, various Buddhist structures, such as the Butkara Stupa in the area of Swat were enlarged and decorated with Hellenistic architectural elements in the 2nd century BCE, especially during the rule of Menander. Stupas were just round mounds when the Indo-Greeks settled in India, possibly with some top decorations, but soon they added various structural and decorative elements, such as reinforcement belts, niches, architectural decorations such as plinthes, toruses and cavettos, plaster painted with decorative scrolls. The niches were probably designed to place statues or friezes, an indication of early Buddhist descriptive art during the time of the Indo-Greeks. Coins of Menander were found within these constructions dating them to around 150 BCE. By the end of Indo-Greek rule and during the Indo-Scythian period (1st century BCE), stupas were highly decorated with colonnated flights of stairs and Hellenistic scrolls of Acanthus leaves.

The end of the first conquests

Back in Bactria a king named Eucratides managed to topple the Euthydemid dynasty around 170 BCE and some years later made himself ruler of the westernmost Indian territories as well, thus weakening the Indo-Greek kingdom and putting a stop to their expansion.

There may also have been setbacks in the east. The Hathigumpha inscription, written by the king of Kalinga, Kharavela, also describes the presence of the Yavana king whose name has been identified as "Demetrius" with his army in eastern India, apparently as far as the city of Rajagriha about 70 km southeast of Pataliputra and one of the foremost Buddhist sacred cities, but claims that this Demetrius ultimately retreated to Mathura on hearing of Kharavela's military successes further south:

"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 and transport."

The interpretation has been challenged, and a presence this far east seems difficult to attest to Demetrius I, who issued no Indian coins whatsoever.

In any case, Eucratides seems to have occupied territory as far as the Indus, between c. 170 BCE and 150 BCE. His advances were ultimately checked by the Indo-Greek king Menander I who asserted himself in the Indian part of the empire, and began the last expansions eastwards.

Consolidation and rise of Menander I

Menander is considered as probably the most successful Indo-Greek king, and the conqueror of the vastest territory. The finds of his coins are the most numerous and the most widespread of all the Indo-Greek kings. In Antiquity, from at least the 1st century CE, the "Menander Mons", or "Mountains of Menander", came to designate the mountain chain at the extreme east of the Indian subcontinent, today's Naga hills and Arakan, as indicated in Ptolemy's world map of the 1st century CE geographer Ptolemy. Menander is also remembered in Buddhist literature, where he 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 numismatic reforms, such as issuing coins with portraits, which had hitherto been unknown in India. His most common coin reverse Athena Alkidemos ("Protector of the people") became a common type for his successors in the East.

Conquests east of the Punjab region were most likely made during the second half of the century by the king Menander I, but his eastern conquests were brief. The following passage may allude to the return of Menander to his home territories, perhaps due to a civil war with the competing king Zoilos I, or the nomad invasion of Bactria:

"The Yavanas, infatuated by war, will not remain in Madhadesa (the Middle Country). There will be mutual agreement among them to leave, due to a terrible and very dreadful war having broken out in their own realm."

Following Menander's reign, about twenty Indo-Greek kings are known to have ruled in succession in the eastern parts of the Indo-Greek territory. Upon his death, Menander was succeeded by his infant son Thraso, but he was apparently murdered and further civil wars ensued. Judging from their coins, many of the later kings claimed descendance from either the Euthydemids or Menander, but the details remain uncertain due to the lack of sources.

The fall of Bactria

From 130 BCE, the Scythians and then the Yuezhi, following a long migration from the border of China, started to invade Bactria from the north. Around 125 BCE, the Greco-Bactrian king Heliocles, was probably killed during the invasion and the Greco-Bactrian kingdom proper ceased to exist. The Indo-Greek kingdom, now entirely isolated from the Hellenistic world, did nevertheless maintain itself, if we can judge from the vast number of coins issued from the following kings, such as Lysias and Antialcidas.

During this time, the Indo-Greek territory seems to have extended from the Paropamisadae and Arachosia in the west, to eastern Punjab, perhaps even with further eastern strongholds such as Mathura (see below). It is uncertain when the coastal provinces along the mouth of the Indus and further east were lost, or how tightly they were ever integrated with the kingdom.

Later History

Throughout the 1st century BCE, 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 king are known during this period, down to the last known Indo-Greek king Strato II, who ruled in the Punjab region until around 10 CE.

Loss of Mathura and eastern territories (after 100 BCE)

The Indo-Greeks may have ruled as far as the area of Mathura until sometime in the 1st century BCE: the Maghera inscription, from a village near Mathura, records the dedication of a well "in the one hundred and sixteenth year of the reign of the Yavanas", which could be as late as 70 BCE. Soon however Indian kings recovered the area of Mathura and south-eastern Punjab, west of the Yamuna River, and started to mint their own coins. The Arjunayanas (area of Mathura) and Yaudheyas mention military victories on their coins ("Victory of the Arjunayanas", "Victory of the Yaudheyas"). During the 1st century BCE, the Trigartas, Audumbaras and finally the Kunindas (closest to Punjab) also started to mint their own coins, usually in a style highly reminiscent of Indo-Greek coinage.

The Western king Philoxenus briefly occupied most of the remaining Greek territory from the Paropamisadae to Western Punjab c. 100 BCE, after which the territories fragmented again. The following decades saw fierce internal fighting between several kings, such as Heliokles II, Strato I and Hermaeus, which contributed to the downfall in a manner perhaps reminiscent of how the Seleucid and Ptolemaic states were torn apart by dynastic wars at the same period.

The Yuezhi expansion (70 BCE–)

Philoxenus was succeeded by Diomedes, probably his son or younger brother, in the west, but his reign was short and he was succeeded by Hermaeus, a king married to the princess Calliope who was likely a daughter of Philoxenus. After a reign of at least one decade, Hermaeus was overthrown by nomad tribes, either the Yuezhi or Sakas When Hermaeus is depicted on his coins riding a horse, he is equipped with the recurve bow and bow-case of the steppes.

In any case, these nomads became the new rulers of the Paropamisadae, and minted vast quantities of posthumous issues of Hermaeus up to around 40 CE, when they blend with the coinage of the Kushan king Kujula Kadphises. The first documented Yuezhi prince, Sapalbizes, ruled around 20 BCE, and minted in Greek and in the same style as the western Indo-Greek kings, probably depending on Greek mints and celators.

Scythian invasions (80 BCE – 50 CE)

Around 80 BCE, an Indo-Scythian king named Maues, possibly an ally of some of the Indo-Greeks kings, captured Taxila and ruled Gandhara for a few years. The king he dethroned was probably Archebius. After Maues' death, the Indo-Greeks were able to regain control of Taxila, but at this time the line between Greeks and Sakas may not have been that clear. Among the kings who emerged in Gandhara after Maues' death, Artemidoros who was seemingly a regular Indo-Greek king, presents himself as "son of Maues" on a bronze. This discovery caused a small sensation and has led scholars such as Senior to assume that also Hermaeus may have been of partly Saka origin.

Another important king during this period was Amyntas, who issued the last Attic coins found in Bactria and may have attempted to reunite the Indo-Greek territories. It was however the king Apollodotus II, seemingly a descendant of Menander, who managed to regain Gandhara from remaining Greek strongholds in eastern Punjab. After the death of Apollodotus II the kingdom fragmented once more.

In the west, he was succeeded by Hippostratos who was initially a successful ruler, but he was the last western ruler: around 55–50 BCE he was defeated by the Indo-Scythian Azes I, who established his own Indo-Scythian dynasty.

Although the Indo-Scythians clearly ruled militarily and politically, they remained 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. The Buner reliefs show Indo-Greeks and Indo-Scythians reveling in a Buddhist context.

The last eastern kingdom (50 BCE – 10 CE)

The Indo-Greeks continued to maintain themselves in the eastern Punjab for several decades, until the kingdom of the last Indo-Greek king Strato II was taken over by the Indo-Scythian ruler Rajuvula around 10 CE. The coins of these Indo-Greek rulers deteriorated constantly, both in terms of artistic quality (due to the long isolation) and in silver content. Still, the last Strato had the honour of ruling the last pocket of an independent Hellenistic state; when he disappeared, Cleopatra, usually seen as the last of the rulers who followed Alexander the Great, was already gone.

Indo-Parthian rule (10–60 CE)

The Parthians, represented by the Suren, a noble Parthian family of Arsacid descent, started to make inroads into the territories which had been occupied by the Indo-Scythians and the Yuezhi, until the demise of the last Indo-Scythian emperor Azes II around 12 BCE. The Parthians ended up controlling all of Bactria and extensive territories in Northern India, after fighting many local rulers such as the Kushan Empire ruler Kujula Kadphises, in the Gandhara region. Around 20, Gondophares, one of the Parthian conquerors, declared his independence from the Parthian empire and established the Indo-Parthian kingdom in the conquered territories, with his capital in Taxila.

Kushan supremacy

The Yuezhi expanded to the east during the 1st century CE, to found the Kushan Empire. The first Kushan emperor Kujula Kadphises ostensibly associated himself with Hermaeus on his coins, suggesting that he may have been one of his descendants by alliance, or at least wanted to claim his legacy. The Yuezhi (future Kushans) were in many ways the cultural and political heirs to the Indo-Greeks, as suggested by their adoption of the Greek culture (writing system, Greco-Buddhist art) and their claim to a lineage with the last western Indo-Greek king Hermaeus.

The last known mention of an Indo-Greek ruler is suggested by an inscription on a signet ring of the 1st century CE in the name of a king Theodamas, from the Bajaur area of Gandhara, in modern Pakistan. No coins of him are known, but the signet bears in kharoshthi script the inscription "Su Theodamasa", "Su" being explained as the Greek transliteration of the ubiquitous Kushan royal title "Shau" ("Shah", "King").

The Indo-Greek rulers

"Indo-Greek" kings are distinguished from "Bactrian" kings in that they issued dominantly bilingual coinage, meant for circulation outside the Hindu Kush. However, Demetrius I is usually included (though he issued no such coins) and some mainly Bactrian kings who also held Indian territories. The chronology is tentative, as are the territories. This overview largely gives the chronology of Senior (2004) while most of the territories are adapted from Bopearachchi (1991). The views of both authors, as well as other alternatives, are given under each king.

The Bactrian period (c. 200–130 BCE)

Territories of Arachosia, Paropamisadae, Gandhara?

Euthydemus I and Demetrius I (c. 200–175 BCE) Coins. Demetrius was the first Indo-Greek king to gain territories in India. It is possible that he made his first conquests as general for his father, a view supported by the Heliodorus inscription.

The territory of Mathura and eastern Punjab may have been lost after Strato's death.

The following minor kings ruled parts of the kingdom:

Territories of the Paropamisadae and Gandhara During the 1st century BCE, the Indo-Greeks progressively lost ground against the invasion of the Indo-Scythians. After the invasion of (Maues), the following kings maintained themselves in the Paropamisadae or Gandhara:

Despite his Greek name, Artemidoros was the son of Maues and therefore formally a Scythian king, and the ethnicity of Telephus is unknown as well.

Territories of Gandhara, western and eastern Punjab

Apollodotus II temporarily united most of the Indo-Greek kingdom, but after his death it fragmented again.

Indo-Greek princelets (Gandhara)

After the Indo-Scythian Kings became the rulers of northern India, remaining Greek communities were probably governed by lesser Greek rulers, without the right of coinage, into the 1st century CE, in the areas of the Paropamisadae and Gandhara:

The Indo-Greeks may have kept a significant military role towards the 2nd century CE as suggested by the inscriptions of the Satavahana kings.
