The Hook: A Greek Who Worshipped Vishnu

Connect

Drive about 55 km north-east of Bhopal to Vidisha, and just outside the town, at Besnagar, stands a modest stone column locals call Khamba Baba (खम्भ बाबा). Its Brahmi inscription says it was set up as a Garuda pillar to Vasudeva by Heliodorus, a Greek from Taxila, who came as an envoy of the Indo-Greek king Antialcidas to the court of a local king, Bhagabhadra. A Greek calling himself a Bhagavata, a devotee of Vishnu, in central India, in the 2nd century BCE.

What happened to north India after the Mauryas fell, and how did Greeks, Shakas and Kushanas become Indian kings?

Why it matters: Prelims asks one-liners on this period every few years: who founded which dynasty, which inscription belongs to whom, and the Shaka era of 78 CE (India’s national calendar). Mains GS-I asks about the cultural results of foreign contact: Gandhara art, Mahayana and trade.


The Big Picture: 185 BCE to c. 300 CE

The Mauryan empire ended in about 185 BCE (dated variously 187–185 BCE). For the next five centuries no single power held north India. Two kinds of rulers filled the gap:

  1. Indian dynasties in the Ganga valley and central India: the Shungas and then the Kanvas.
  2. Rulers who came through the north-western passes: Indo-Greeks, Shakas, Parthians and Kushanas.

    c. 185 BCE : Pushyamitra Shunga kills the last Mauryan, Brihadratha
    2nd century BCE : Indo-Greek kings in the north-west, Menander at Sakala
    c. 73 BCE : Vasudeva Kanva replaces the last Shunga, Devabhuti
    1st century BCE : Shakas spread to Taxila, Mathura, western India
    1st century CE : Parthian Gondophernes; Kushanas under Kujula and Vima Kadphises
    78 CE : Start of the Shaka era, usually linked with Kanishka's accession
    150 CE : Junagadh inscription of the Shaka ruler Rudradaman I

The Shungas (शुंग वंश), c. 185–73 BCE

PointDetail
FounderPushyamitra Shunga (पुष्यमित्र शुंग), a Brahmana and the Mauryan commander-in-chief
HowKilled the last Mauryan king Brihadratha during an army review
CapitalPataliputra; Vidisha was a key regional centre
Vedic revivalPushyamitra performed Ashvamedha sacrifices (the Ayodhya inscription of Dhanadeva credits him with two)
LiteratureThe grammarian Patanjali (पतंजलि), author of the Mahabhashya, is generally placed in his time
Greek warsKalidasa’s play Malavikagnimitram says Pushyamitra’s grandson Vasumitra defeated the Yavanas (Greeks) on the banks of the Sindhu
AgnimitraPushyamitra’s son, viceroy at Vidisha, hero of Malavikagnimitram
Last kingDevabhuti, killed in a plot by his minister Vasudeva Kanva

Buddhism under the Shungas: the Buddhist text Divyavadana paints Pushyamitra as a persecutor of Buddhists. Historians treat this with caution, because the great Buddhist monuments at Bharhut and the stone enlargement of the Sanchi stupa belong to the Shunga period. Write “the persecution story is from a hostile source and is disputed”.

Art: the railings and gateway of the Bharhut stupa (Satna, Madhya Pradesh) carry labelled relief panels of Jataka stories. They are among the earliest narrative sculpture in India.

The Kanvas (कण्व वंश), c. 73–28 BCE

  • Founded by Vasudeva Kanva; four kings in all, ruling for roughly 45 years.
  • They ruled a shrunken Magadha. According to the Puranas, the last Kanva, Susharman, was overthrown by the Andhra (Satavahana) king Simuka. The chronology here does not fit neatly, and historians flag the problem.

The Indo-Greeks (हिन्द-यवन)

After Alexander, Greek kingdoms grew up in Bactria (north Afghanistan). Pressed by the Parthians and Central Asian tribes, Bactrian Greeks moved into north-west India from the early 2nd century BCE.

KingWhat to remember
DemetriusUsually credited with leading the first Bactrian Greek advance into India
Menander (Milinda, मिलिंद)The most famous. Capital Sakala (modern Sialkot). Discussed Buddhism with the monk Nagasena; their dialogue is the Pali text Milindapanho (The Questions of King Milinda). Tradition says he became a Buddhist
AntialcidasSent Heliodorus to the court of Bhagabhadra at Vidisha (Besnagar pillar)

Contribution:

  • Coins: standard textbooks (R. S. Sharma’s NCERT text) note that the Indo-Greeks were the first rulers in India to issue coins that can be definitely attributed to named kings, with portraits and legends. The same texts credit them with the first gold coins in India; this became large-scale only under the Kushanas.
  • Hellenistic art in the north-west, which fed into the Gandhara school.
  • Astronomy and drama: Greek influence on Indian astronomy (Sanskrit hora from Greek hora), and the word yavanika for the stage curtain.

The Shakas (शक) and the Western Kshatrapas

The Shakas (Scythians) came from Central Asia and pushed the Greeks out of much of the north-west. They set up several branches, each ruled by governors with the Persian titles Kshatrapa and Mahakshatrapa.

BranchCentreKey ruler
KshaharatasWestern India and north Maharashtra (Nasik area)Nahapana, defeated by the Satavahana king Gautamiputra Satakarni
KardamakasUjjain and SaurashtraChashtana; his grandson Rudradaman I
OthersTaxila, MathuraSmaller Kshatrapa houses

Rudradaman I (रुद्रदामन) and the Junagadh Inscription

PointDetail
InscriptionJunagadh (Girnar) rock inscription, 150 CE (year 72 of the Shaka era)
LanguageSanskrit: the first long inscription in fairly pure Sanskrit. Earlier royal records were in Prakrit
RockThe same Girnar rock carries Ashoka’s Major Rock Edicts. Later, Skandagupta’s inscription was also added
ContentRepair of the Sudarshana lake (सुदर्शन झील) after a storm burst its embankment
History of the lakeBuilt by Pushyagupta, Chandragupta Maurya’s governor; fitted with channels under Ashoka by the Yavana Tushaspha
Satavahana linkRudradaman claims he twice defeated Satakarni, lord of Dakshinapatha, but spared him because of a close (marriage) relationship

The Western Kshatrapas of Ujjain lasted until Chandragupta II of the Gupta dynasty defeated the last of them, Rudrasimha III, around the end of the 4th century CE.

Vikram Samvat: tradition, not proof
A popular tradition says a king Vikramaditya of Ujjain drove out the Shakas in 57–58 BCE and started the Vikram Samvat (विक्रम संवत्). No contemporary inscription proves this king existed; the era was known earlier by other names (such as the Krita and Malava eras). Treat the story as tradition.

The Parthians (पह्लव)

  • Also called Pahlavas; they came from Iran and ruled parts of the north-west, overlapping with the Shakas.
  • Best-known king: Gondophernes (Gondophares), named in the Takht-i-Bahi inscription (near Peshawar).
  • Christian tradition says St Thomas the Apostle came to India and visited Gondophernes’ court. Write it as a tradition.

The Kushanas (कुषाण)

The Kushanas were one branch of the Yuezhi (Yueh-chi), a Central Asian people. They built an empire that stretched from Central Asia and Afghanistan to the Ganga valley, and controlled a large part of the Silk Route.

RulerWhat to remember
Kujula KadphisesFounder of Kushana power south of the Hindu Kush; issued copper coins
Vima KadphisesIssued gold coins on a large scale; coins show Shiva and the title Maheshvara, so he is usually described as a Shaiva
Kanishka (कनिष्क)The greatest Kushana. Accession usually placed in 78 CE, the start of the Shaka era. Capitals Purushapura (Peshawar) and Mathura
Huvishka, Vasudeva ILater rulers; Vasudeva’s name shows deep Indianisation

Kanishka

  • Date problem: 78 CE is the date most textbooks and exams use. Some scholars, using the Bactrian-language Rabatak inscription (found in Afghanistan in 1993) and other evidence, place him later, around 127 CE. For Prelims use 78 CE; in Mains you can note the debate.
  • Shaka era (शक संवत्): begins in 78 CE. The Saka calendar was adopted as India’s national calendar in 1957.
  • Buddhism: patron of Mahayana. The Fourth Buddhist Council was held under him in Kashmir (traditionally at Kundalvana), with Vasumitra as president and Ashvaghosha as vice-president. Some traditions place it at Jalandhar.
  • Court scholars (by tradition): Ashvaghosha (अश्वघोष), author of the Buddhacharita; Vasumitra; the physician Charaka; the Mahayana philosopher Nagarjuna is also linked to this age, though most place him a little later and in the Deccan.
  • Coins: the Buddha appears on some of his coins with the Greek-script label Boddo, along with Greek, Iranian and Indian gods.
  • Title and image: used the title Devaputra (“son of god”). A headless statue of Kanishka was found at Mat, near Mathura.
Cultural results of the foreign rulers
  1. Assimilation: Greeks, Shakas and Kushanas took Indian names and religions (Heliodorus a Vaishnava, Menander a Buddhist, Vima a Shaiva, Rudradaman a patron of Sanskrit).
  2. Coins and trade: portrait coinage and plentiful Kushana gold reflect booming trade with Central Asia, China and the Roman world.
  3. Mahayana Buddhism spread from the Kushana empire into Central Asia and China.
  4. New art schools: Gandhara and Mathura (below).
  5. Military and dress: cavalry, the use of the reins and saddle, and tunics, trousers and boots are often traced to this contact.
  6. Sanskrit in inscriptions: began with Rudradaman’s Junagadh record.

Gandhara and Mathura Schools of Sculpture

The Buddha was shown only by symbols (footprints, the Bodhi tree, an empty seat, the wheel) in earlier art. In the Kushana age he appears in human form, in two schools at once.

FeatureGandhara school (गांधार शैली)Mathura school (मथुरा शैली)
RegionNorth-west: Peshawar valley, Taxila, AfghanistanMathura (Uttar Pradesh)
MaterialGrey-blue schist, also stuccoSpotted red sandstone
InfluenceGreco-Roman (Hellenistic)Largely indigenous
Buddha’s lookWavy hair, heavy folded robes, a calm, spiritual face; Apollo-likeShaven or snail-shell curls, smiling, fleshy; robe over one shoulder, light and clinging
ThemesMainly BuddhistBuddhist, Jain and Brahmanical (Vishnu, Shiva, yakshas)
PatronsKushanasKushanas
Which school made the first Buddha image?
Scholars disagree whether Gandhara or Mathura carved the first Buddha image. Many now see both as developing in the Kushana period, more or less in parallel. Do not write that one school “copied” the other.

Memory Tricks

Order of the north-western arrivals: 'Good Students Pass Kindly'
Greeks (Indo-Greeks) → Shakas → Parthians (Pahlavas) → Kushanas. That is the broad order in which they became powerful in north-west India.
'Push the Bri out, Vasu the Devil out'
Pushyamitra pushed out Brihadratha (end of the Mauryas). Vasudeva Kanva pushed out Devabhuti (end of the Shungas).
'Seventy-eight, Shaka gate'
78 CE opens the Shaka era. Add 78 to a Shaka year to get the CE year: the Junagadh inscription’s year 72 + 78 = 150 CE.

Don’t Confuse

ThisvsThat
Heliodorus: Greek envoy, Besnagar (Vidisha) Garuda pillarHarishena: Samudragupta’s poet, Prayag Prashasti
Menander: Indo-Greek, Sakala, MilindapanhoGondophernes: Parthian, Takht-i-Bahi
Nahapana: Kshaharata, Nasik area, beaten by GautamiputraRudradaman I: Kardamaka, Ujjain, Junagadh inscription
Shaka era: 78 CEVikram Samvat: 57–58 BCE
Gandhara: grey schist, Greco-RomanMathura: red sandstone, indigenous
Ashvaghosha: vice-president of the Fourth CouncilVasumitra: president of the Fourth Council

Common Mistakes

Trap 1: the first Sanskrit inscription
The Junagadh inscription of Rudradaman I (150 CE) is the first long inscription in fairly pure Sanskrit. Ashoka’s edicts on the same rock are in Prakrit. Options sometimes offer the Hathigumpha or the Nasik inscription, which are both Prakrit.
Trap 2: who built the Sudarshana lake
Rudradaman repaired the lake; he did not build it. It was built under Chandragupta Maurya by his governor Pushyagupta, and later repaired again under Skandagupta.
Trap 3: Kanishka's council
The Fourth Buddhist Council (Kashmir, Kanishka) is often confused with the Third (Pataliputra, Ashoka, Moggaliputta Tissa). Kanishka’s council is linked with Mahayana.
Trap 4: Shungas and Buddhism
“Pushyamitra destroyed all Buddhist monuments” is not a safe statement. The source is a hostile Buddhist text, and Bharhut and Sanchi flourished in Shunga times.

Practice

These are original practice questions written in CGPSC style. They are not previous-year questions.

Level 1: Foundation

  1. The founder of the Shunga dynasty, ________, killed the last Mauryan king ________.
  2. The dialogue between Menander and the monk Nagasena is recorded in the Pali text ________.
  3. The Shaka era begins in ________ CE and is usually linked with the accession of ________.
Answers
  1. Pushyamitra Shunga; Brihadratha
  2. Milindapanho
  3. 78; Kanishka

Level 2: Prelims MCQs

Q1. Consider the following statements about the Junagadh rock inscription of Rudradaman I:

  1. It is written in Prakrit.
  2. It records the repair of the Sudarshana lake.
  3. It says Rudradaman defeated the lord of Dakshinapatha twice but did not destroy him.

Which of the statements given above is/are correct?

(a) 1 and 2 only (b) 2 and 3 only (c) 3 only (d) 1, 2 and 3

Answer and explanation
(b) 2 and 3 only. The inscription (150 CE) is in Sanskrit, which is why it is famous as the first long Sanskrit inscription; statement 1 is wrong. It records the repair of the Sudarshana lake and Rudradaman’s claim that he twice defeated Satakarni, lord of Dakshinapatha, but spared him because of a close relationship.

Q2. Match List-I (Ruler) with List-II (Associated evidence or event):

List-IList-II
A. Antialcidas1. Takht-i-Bahi inscription
B. Gondophernes2. Besnagar Garuda pillar
C. Kanishka3. Rabatak inscription
D. Gautamiputra Satakarni4. Restruck coins of Nahapana

(a) A-2, B-1, C-3, D-4 (b) A-1, B-2, C-3, D-4 (c) A-2, B-1, C-4, D-3 (d) A-3, B-1, C-2, D-4

Answer and explanation
(a) A-2, B-1, C-3, D-4. Heliodorus, envoy of Antialcidas, set up the Besnagar pillar. Gondophernes appears in the Takht-i-Bahi inscription. The Bactrian-language Rabatak inscription gives Kanishka’s genealogy. Gautamiputra overstruck Nahapana’s silver coins after defeating him.

Q3. Which one of the following pairs is not correctly matched?

(a) Patanjali : Mahabhashya (b) Ashvaghosha : Buddhacharita (c) Nagasena : Milindapanho (d) Agnimitra : Mudrarakshasa

Answer and explanation
(d). Agnimitra Shunga is the hero of Kalidasa’s Malavikagnimitram. Mudrarakshasa is Vishakhadatta’s play about Chanakya and Chandragupta Maurya. Nagasena is the monk who answers King Milinda’s questions in the Milindapanho.

Q4. Which of the following is a feature of the Mathura school of art but not of the Gandhara school?

(a) Use of grey-blue schist (b) Heavy, wavy-haired Buddha figures in Greco-Roman style (c) Use of spotted red sandstone and images of Jain tirthankaras and Hindu deities (d) Patronage by the Kushanas

Answer and explanation
(c). Mathura used spotted red sandstone and carved Buddhist, Jain and Brahmanical images. Schist and Greco-Roman style (options a and b) mark Gandhara. Option (d) is common to both, so it does not separate them.

Q5. Arrange in chronological order:

  1. Junagadh inscription of Rudradaman I
  2. Pushyamitra Shunga’s seizure of power
  3. Start of the Shaka era
  4. Vasudeva Kanva’s seizure of power

(a) 2-4-3-1 (b) 2-3-4-1 (c) 4-2-3-1 (d) 2-4-1-3

Answer and explanation
(a) 2-4-3-1. Pushyamitra (c. 185 BCE), Vasudeva Kanva (c. 73 BCE), the Shaka era (78 CE), Junagadh inscription (150 CE).

Level 3: Mains Answer Writing

Q1. What were the cultural consequences of the rule of foreign dynasties in north-west India between 200 BCE and 300 CE? (150–200 words)

Model answer outline

Intro: After the Mauryas, Indo-Greeks, Shakas, Parthians and Kushanas ruled north-west and western India. They were absorbed into Indian society rather than staying apart from it.

Body:

  1. Religion: foreigners adopted Indian faiths: Heliodorus (Vaishnava, Besnagar pillar), Menander (Buddhist), Vima Kadphises (Shaiva), Kanishka (Mahayana, Fourth Council).
  2. Art: the Buddha in human form; the Gandhara (Greco-Roman, schist) and Mathura (indigenous, red sandstone) schools.
  3. Coinage and economy: portrait coins with legends; Kushana gold; control of the Silk Route linked India with China, Central Asia and Rome.
  4. Language: Rudradaman’s Junagadh inscription (150 CE) opened the era of Sanskrit royal records.
  5. Science and drama: Greek terms in astronomy (hora), yavanika in theatre.
  6. Society: foreigners were fitted into the varna order, often as “fallen Kshatriyas” in the law books.

Conclusion: These centuries of political division were culturally rich, and they prepared the ground for the classical synthesis of the Gupta age.
