Greco-Bactrian Kingdom

In an inscription found in the Kuliab area of Tadjikistan, in eastern Greco-Bactria, and dated to 200–195 BC,[17] a Greek by the name of Heliodotos, dedicating a fire altar to Hestia, mentions Euthydemus as the greatest of all kings, and his son Demetrius I as "Demetrios Kalinikos" "Demetrius the Glorious Conqueror":[18][17]

"Heliodotos dedicated this fragrant altar for Hestia, venerable goddess, illustrious amongst all, in the grove of Zeus, with beautiful trees; he made libations and sacrifices so that the greatest of all kings Euthydemos, as well as his son, the glorious, victorious and remarkable Demetrios, be preserved of all pains, with the help of Tyche with divine thoughts." — Kuliab inscription, 200–195 BCE[19][20]	τόνδε σοι βωμὸν θυώδη, πρέσβα κυδίστη θεῶν Ἑστία, Διὸς κ(α)τ᾽ ἄλσος καλλίδενδρον ἔκτισεν καὶ κλυταῖς ἤσκησε λοιβαῖς ἐμπύροις Ἡλιόδοτος ὄφρα τὸμ πάντων μέγιστον Εὐθύδημον βασιλέων τοῦ τε παῖδα καλλίνικον ἐκπρεπῆ Δημήτριον πρευμενὴς σώιζηις ἐκηδεῖ(ς) σὺν τύχαι θεόφρον[ι]

Probable statuette of a Greek soldier, wearing a version of the Greek Phrygian helmet, from a 3rd-century BC burial site north of the Tian Shan, Xinjiang Region Museum, Ürümqi.

To the north, Euthydemus also ruled Sogdiana and Ferghana, and there are indications that from Alexandria Eschate the Greco-Bactrians may have led expeditions as far as Kashgar and Ürümqi in Xinjiang, leading to the first known contacts between China and the West around 220 BC. The Greek historian Strabo too writes that: "they extended their empire even as far as the Seres (Chinese) and the Phryni". (Strabo, XI.XI.I).[10]

Several statuettes and representations of Greek soldiers have been found north of the Tian Shan, on the doorstep to China, and are today on display in the Xinjiang museum at Ürümqi (Boardman).[21] Middle Eastern or Greek influences on Chinese art have also been suggested (Hirth, Rostovtzeff). Designs with rosette flowers, geometric lines, and glass inlays, suggestive of Egyptian, Persian, and/or Hellenistic influences,[22] can be found on some early Han dynasty bronze mirrors.[23]

Some speculate that Greek influence is found in the artworks of the burial site of China's first Emperor Qin Shi Huang, dating back to the 3rd century BC, including in the manufacture of the famous Terracotta army. This idea suggested that Greek artists may have come to China at that time to train local artisans in making sculptures[24][25] However, this idea is disputed.[26]

Numismatics also suggest that some technology exchanges may have occurred on these occasions: the Greco-Bactrians were the first in the world to issue cupro-nickel (75/25 ratio) coins,[27] an alloy technology only known by the Chinese at the time under the name "White copper" (some weapons from the Warring States period were in copper-nickel alloy).[28] The practice of exporting Chinese metals, in particular iron, for trade is attested around that period. Kings Euthydemus, Euthydemus II, Agathocles and Pantaleon made these coin issues around 170 BC and it has alternatively been suggested that a nickeliferous copper ore was the source from mines at Anarak.[29] Copper-nickel would not be used again in coinage until the 19th century.

The presence of Chinese people in India from ancient times is also suggested by the accounts of the "Ciñas" in the Mahabharata and the Manu Smriti. The Han dynasty explorer and ambassador Zhang Qian visited Bactria in 126 BC, and reported the presence of Chinese products in the Bactrian markets:

"When I was in Bactria (Daxia)", Zhang Qian reported, "I saw bamboo canes from Qiong and cloth made in the province of Shu (territories of southwestern China). When I asked the people how they had gotten such articles, they replied, "Our merchants go buy them in the markets of Shendu (India)." (Shiji 123, Sima Qian, trans. Burton Watson).

The purpose of Zhang Qian's journey was to look for civilizations on the steppe that the Han could ally with against the Xiongnu. Upon his return, Zhang Qian informed the Chinese emperor Han Wudi of the level of sophistication of the urban civilizations of Ferghana, Bactria and Parthia, who became interested in developing commercial relationships with them:

The Son of Heaven on hearing all this reasoned thus: Ferghana (Dayuan) and the possessions of Bactria (Daxia) and Parthia (Anxi) are large countries, full of rare things, with a population living in fixed abodes and given to occupations somewhat identical with those of the Chinese people, and placing great value on the rich produce of China. (Hanshu, Former Han History).

A number of Chinese envoys were then sent to Central Asia, triggering the development of the Silk Road from the end of the 2nd century BC.[30]

The Indian emperor Chandragupta, founder of the Mauryan dynasty, conquered the northwestern subcontinent upon the death of Alexander the Great around 323 BC. However, contacts were kept with his Greek neighbours in the Seleucid Empire, a dynastic alliance or the recognition of intermarriage between Greeks and Indians were established (described as an agreement on Epigamia in Ancient sources), and several Greeks, such as the historian Megasthenes, resided at the Mauryan court. Subsequently, each Mauryan emperor had a Greek ambassador at his court.

Kandahar Bilingual Rock Inscription of Ashoka (in Greek and Aramaic), found in Kandahar. Circa 250 BC, Kabul Museum.

Chandragupta's grandson Ashoka converted to the Buddhist faith and became a great proselytizer in the line of the traditional Pali canon of Theravada Buddhism, directing his efforts towards the Indo-Iranic and the Hellenistic worlds from around 250 BC. According to the Edicts of Ashoka, set in stone, some of them written in Greek, he sent Buddhist emissaries to the Greek lands in Asia and as far as the Mediterranean. The edicts name each of the rulers of the Hellenistic world at the time.

The conquest by Dharma has been won here, on the borders, and even six hundred yojanas (4,000 miles) away, where the Greek king Antiochos rules, beyond there where the four kings named Ptolemy, Antigonos, Magas and Alexander rule, likewise in the south among the Cholas, the Pandyas, and as far as Tamraparni. (Edicts of Ashoka, 13th Rock Edict, S. Dhammika).

Some of the Greek populations that had remained in northwestern India apparently converted 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. (Edicts of Ashoka, 13th Rock Edict, S. Dhammika).

Furthermore, according to Pali sources, some of Ashoka's emissaries were Greek Buddhist monks, indicating close religious exchanges between the two cultures:

When the thera (elder) Moggaliputta, the illuminator of the religion of the Conqueror (Ashoka), had brought the (third) council to an end... he sent forth theras, one here and one there: ...and to Aparantaka (the "Western countries" corresponding to Gujarat and Sindh) he sent the Greek (Yona) named Dhammarakkhita... and the thera Maharakkhita he sent into the country of the Yona. (Mahavamsa, XII).

Greco-Bactrians probably received these Buddhist emissaries (at least Maharakkhita, lit. "The Great Saved One", who was "sent to the country of the Yona") and somehow tolerated the Buddhist faith, although little proof remains. In the 2nd century AD, the Christian dogmatist Clement of Alexandria recognized the existence of Buddhist Sramanas among the Bactrians ("Bactrians" meaning "Oriental Greeks" in that period), and even their influence on Greek thought:

Thus philosophy, a thing of the highest utility, flourished in antiquity among the barbarians, shedding its light over the nations. And afterwards it came to Greece. First in its ranks were the prophets of the Egyptians; and the Chaldeans among the Assyrians; and the Druids among the Gauls; and the Sramanas among the Bactrians ("Σαρμαναίοι Βάκτρων"); and the philosophers of the Celts; and the Magi of the Persians, who foretold the Saviour's birth, and came into the land of Judea guided by a star. The Indian gymnosophists are also in the number, and the other barbarian philosophers. And of these there are two classes, some of them called Sramanas ("Σαρμάναι"), and others Brahmins ("Βραφμαναι"). (Clement of Alexandria "The Stromata, or Miscellanies" Book I, Chapter XV)[31]

One of the Hellenistic-inspired "flame palmettes" and lotus designs, which may have been transmitted through Ai-Khanoum. Rampurva bull capital, India, circa 250 BC.

The Greco-Bactrian city of Ai-Khanoum, being located at the doorstep of India, interacting with the Indian subcontinent, and having a rich Hellenistic culture, was in a unique position to influence Indian culture as well. It is considered that Ai-Khanoum may have been one of the primary actors in transmitting Western artistic influence to India, for example in the creation of the Pillars of Ashoka or the manufacture of the quasi-Ionic Pataliputra capital, all of which were posterior to the establishment of Ai-Khanoum.[32]

The scope of adoption goes from designs such as the bead and reel pattern, the central flame palmette design and a variety of other moldings, to the lifelike rendering of animal sculpture and the design and function of the Ionic anta capital in the palace of Pataliputra.[33]

Coin of Greco-Bactrian king Agathocles with Indian deities.

Indian coinage of Agathocles, with Buddhist lion and dancing woman holding lotus, possible Indian goddess Lakshmi.

One of the last Greco-Bactrian kings, Agathocles of Bactria (ruled 190–180 BC), issued remarkable Indian-standard square coins bearing the first known representations of Indian deities, which have been variously interpreted as Vishnu, Shiva, Vasudeva, Buddha or Balarama. Altogether, six such Indian-standard silver drachmas in the name of Agathocles were discovered at Ai-Khanoum in 1970.[34][35][36] These coins seem to be the first known representations of Vedic deities on coins, and they display early Avatars of Vishnu: Balarama-Sankarshana with attributes consisting of the Gada mace and the plow, and Vasudeva-Krishna with the Vishnu attributes of the Shankha (a pear-shaped case or conch) and the Sudarshana Chakra wheel.[35] Some other coins by Agathocles are also thought to represent the Buddhist lion and the Indian goddess Lakshmi, consort of Vishnu.[36] The Indian coinage of Agathocles is few but spectacular. These coins at least demonstrate the readiness of Greek kings to represent deities of foreign origin. The dedication of a Greek envoy to the cult of Garuda at the Heliodorus pillar in Besnagar could also be indicative of some level of religious syncretism.

Silver coin depicting Demetrius I of Bactria (reigned c. 200–180 BC), wearing an elephant scalp, symbol of his conquests in northwest Indian subcontinent.

Demetrius, the son of Euthydemus, started an invasion of the subcontinent from 180 BC, a few years after the Mauryan empire had been overthrown by the Shunga dynasty. Historians differ on the motivations behind the invasion. Some historians suggest that the invasion of the subcontinent was intended to show their support for the Mauryan empire, and to protect the Buddhist faith from the religious persecutions of the Shungas as alleged by Buddhist scriptures (Tarn). Other historians have argued however that the accounts of these persecutions have been exaggerated (Thapar, Lamotte).

Demetrius may have been as far as the imperial capital Pataliputra in today's eastern India (today Patna). However, these campaigns are typically attributed to Menander. The invasion was completed by 175 BC. This established in the northwestern Indian Subcontinent what is called the Indo-Greek Kingdom, which lasted for almost two centuries until around AD 10. The Buddhist faith flourished under the Indo-Greek kings, foremost among them Menander I. It was also a period of great cultural syncretism, exemplified by the development of Greco-Buddhism.

During or after his Indian campaigns, Eucratides was attacked and defeated by the Parthian king Mithridates I, possibly in alliance with partisans of the Euthydemids:

Gold 20-stater of Eucratides, the largest gold coin of Antiquity. The coin weighs 169.2 grams, and has a diameter of 58 millimeters.

The Bactrians, involved in various wars, lost not only their rule but also their freedom, as, exhausted by their wars against the Sogdians, the Arachotes, the Dranges, the Arians and the Indians, they were finally crushed, as if drawn of all their blood, by an enemy weaker than them, the Parthians. (Justin, XLI,6)[37]

Following his victory, Mithridates I gained Bactria's territory west of the Arius, the regions of Tapuria and Traxiane: "The satrapy Turiva and that of Aspionus were taken away from Eucratides by the Parthians." (Strabo XI.11.20)[14]

In the year 141 BC, the Greco-Bactrians seem to have entered in an alliance with the Seleucid king Demetrius II to fight again against Parthia:

The people of the Orient welcomed his (Demetrius II's) arrival, partly because of the cruelty of the Arsacid king of the Parthians, partly because, used to the rule of the Macedonians, they disliked the arrogance of this new people. Thus, Demetrius, supported by the Persians, Elymes and Bactrians, routed the Parthians in numerous battles. At the end, deceived by a false peace treaty, he was taken prisoner. (Justin XXXVI, 1,1)[38]

The 5th-century historian Orosius reports that Mithridates I managed to occupy territory between the Indus and the Hydaspes towards the end of his reign (c. 138 BC, before his kingdom was weakened by his death in 136 BC).[39]

Heliocles I ended up ruling what territory remained. The defeat, both in the west and the east, may have left Bactria very weakened and open to nomadic invasions.

The migrations of the Yuezhi through Central Asia, from around 176 BC to AD 30

A nomadic steppe people called the Yuezhi inhabited a region thousands of miles to the east of Bactria on the edges of the Han Empire called the Hexi Corridor. Shortly before 176 BC, the Xiongnu invaded the Hexi Corridor, forcing the Yuezhi to flee the region. In 162 BC the Yuezhi were driven west to the Ili River valley by the Xiongnu. In 132 they were driven out of the Ili valley by the Wusun. The surviving Yuezhi migrated again south towards the territory just north of the Oxus River where they encountered and expelled a nomadic steppe nation called the Sakas.[40]

Gold artefacts of the Scythians in Bactria, at the site of Tillia tepe

Around 140 BC, eastern Scythians (the Saka, or Sacaraucae of Greek sources), apparently being pushed forward by the southward migration of the Yuezhi started to invade various parts of Parthia and Bactria. Their invasion of Parthia is well documented: they attacked in the direction of the cities of Merv, Hecatompolis and Ecbatana. They managed to defeat and kill the Parthian king Phraates II, son of Mithridates I, routing the Greek mercenary troops under his command (troops he had acquired during his victory over Antiochus VII). Again in 123 BC, Phraates's successor, his uncle Artabanus I, was killed by the Scythians.[41]

When the Han Chinese diplomat Zhang Qian visited the Yuezhi in 126 BC, trying to obtain their alliance to fight the Xiongnu, he explained that the Yuezhi were settled north of the Oxus but also held under their sway the territory south of Oxus, which makes up the remainder of Bactria.

According to Zhang Qian, the Yuezhi represented a considerable force of between 100,000 and 200,000 mounted archer warriors,[42] with customs identical to those of the Xiongnu, which would probably have easily defeated Greco-Bactrian forces (in 208 BC when the Greco-Bactrian king Euthydemus I confronted the invasion of the Seleucid king Antiochus III the Great, he commanded 10,000 horsemen).[15] Zhang Qian actually visited Bactria (named Daxia in Chinese) in 126 BC, and portrays a country which was totally demoralized and whose political system had vanished, although its urban infrastructure remained:

Daxia (Bactria) is located over 2,000 li southwest of Dayuan, south of the Gui (Oxus) river. Its people cultivate the land and have cities and houses. Their customs are like those of Dayuan. It has no great ruler but only a number of petty chiefs ruling the various cities. The people are poor in the use of arms and afraid of battle, but they are clever at commerce. After the Great Yuezhi moved west and attacked Daxia, the entire country came under their sway. The population of the country is large, numbering some 1,000,000 or more persons. The capital is called the city of Lanshi (Bactra) and has a market where all sorts of goods are bought and sold. (Records of the Great Historian by Sima Qian, quoting Zhang Qian, trans. Burton Watson)

The Yuezhi further expanded southward into Bactria around 120 BC, apparently further pushed out by invasions from the northern Wusun. It seems they also pushed Scythian tribes before them, which continued to India, where they came to be identified as Indo-Scythians.

Silver coin of Heliocles (r. 150–125 BC), the last Greco-Bactrian king. The Greek inscription reads: ΒΑΣΙΛΕΩΣ ΔΙΚΑΙΟΥ ΗΛΙΟΚΛΕΟΥΣ – "(of) King Heliocles the Just".

The invasion is also described in western Classical sources from the 1st century BC:

The best known tribes are those who deprived the Greeks of Bactriana, the Asii, Pasiani, Tochari, and Sacarauli, who came from the country on the other side of the Jaxartes, opposite the Sacae and Sogdiani.
(Strabo, XI.8.1 [43])

Around that time the king Heliocles abandoned Bactria and moved his capital to the Kabul valley, from where he ruled his Indian holdings. Having left the Bactrian territory, he is technically the last Greco-Bactrian king, although several of his descendants, moving beyond the Hindu Kush, would form the western part of the Indo-Greek kingdom. The last of these "western" Indo-Greek kings, Hermaeus, would rule until around 70 BC, when the Yuezhi again invaded his territory in the Paropamisadae (while the "eastern" Indo-Greek kings would continue to rule until around AD 10 in the area of the Punjab region).

Overall, the Yuezhi remained in Bactria for more than a century. They became Hellenized to some degree, as suggested by their adoption of the Greek alphabet to write their Iranian language, and by numerous remaining coins, minted in the style of the Greco-Bactrian kings, with the text in Greek.

Around 12 BC the Yuezhi then moved further to northern India where they established the Kushan Empire.

Territories of Bactria, Sogdiana, Ferghana, Arachosia:

• Diodotus I (reigned c. 250–240 BC) Coins
• Diodotus II (reigned c. 240–230 BC) Son of Diodotus I Coins

The existence of a third Diodotid king, Antiochus Nicator, perhaps a younger son of Diodotus I, has recently been suggested.

Many of the dates, territories, and relationships between Greco-Bactrian kings are tentative and essentially based on numismatic analysis and a few Classical sources. The following list of kings, dates and territories after the reign of Demetrius is derived from the latest and most extensive analysis on the subject, by Osmund Bopearachchi (Monnaies Gréco-Bactriennes et Indo-Grecques, Catalogue Raisonné, 1991).

Territories of Bactria, Sogdiana, Ferghana, Arachosia:

• Euthydemus I (reigned c. 223-c. 200 BC) Overthrew Diodotus II. Coins

Demetrios I Baktria (c. 205–171 BC). founder of the Indo-Greek kingdom The Greek inscription reads: ΒΑΣΙΛΕΩΣ ΔΗΜΗΤΡΙΟΥ – "(of) King Demetrius

The descendants of the Greco-Bactrian king Euthydemus invaded northern India around 190 BC. Their dynasty was probably thrown out of Bactria after 170 BC by the new king Eucratides but remained in the Indian domains of the empire at least until the 150s BC.

• Demetrius I (reigned c. 200–180 BC) Son of Euthydemus I. Greco-Bactrian king, and conqueror of India. Coins

The territory won by Demetrius was separated between western and eastern parts, ruled by several sub-kings and successor kings:

Territory of Bactria

Silver coin of Antimachus I. The Greek inscription reads: ΒΑΣΙΛΕΩΣ ΘΕΟΥ ΑΝΤΙΜΑΧΟΥ – "(of) King God Antimachus".

• Euthydemus II (c. 180 BC), probably a son of Demetrius. Coins
• Antimachus I (possibly c. 185–170 BC), brother of Demetrius. Defeated by usurper Eucratides. Coins

Territories of Paropamisadae, Arachosia, Gandhara, Punjab

• Pantaleon (190s or 180s BC) Possibly another brother and co-ruler of Demetrius I.
• Agathocles (c. 190–180 BC) Yet another brother? Coins
• Apollodotus I (reigned c. 180–160 BC) A fourth brother?
• Antimachus II Nikephoros (160–155 BC)
• Demetrius II (155–150 BC) Coins
• Menander (reigned c. 155–130 BC). Legendary for the size of his Kingdom, and his support of the Buddhist faith. It is unclear whether he was related to the other kings, and thus if the dynasty survived further.Coins
• Followed by Indo-Greek kings in northern India.

Silver tetradrachm of King Eucratides 171–145 BC. The Greek inscription reads: ΒΑΣΙΛΕΩΣ ΜΕΓΑΛΟΥ ΕΥΚΡΑΤΙΔΟΥ – "(of) King Great Eucratides".

Territory of Bactria and Sogdiana

• Eucratides I 170-c. 145 BC Coins
• Plato co-regent c. 166 BC
• Eucratides II 145–140 BC Coins
• Heliocles (r. c. 145–130 BC).

Heliocles, the last Greek king of Bactria, was invaded by the nomadic tribes of the Yuezhi from the North. Descendants of Eucratides may have ruled on in the Indo-Greek kingdom.

Silver drachm of Menander I, dated circa 160-145 BC. Obverse: ΒΑΣΙΛΕΩΣ ΣΩΤΗΡΟΣ ΜΕΝΑΝΔΡΟΥ ('of King Menander the Saviour'), heroic bust of Menander, viewed from behind, head turned to left; Reverse: Athena standing right, brandishing thunderbolt and holding aegis, Karosthi legend around, monogram in field to left.
