The Hook: The War Next Door

Connect

Drive east from Raipur through Mahasamund and you reach Odisha, the land the ancients called Kalinga (कलिंग). Around 261 BCE, Ashoka’s army conquered it. His own inscription admits that one hundred and fifty thousand people were deported, one hundred thousand were killed and many more died.

Rulers usually boast about victories. Ashoka carved his remorse in stone, and in the same edict warned the forest peoples (atavikas) of his frontiers, the kind of communities that lived in the hills and forests of central India, that his compassion had limits. How did a conqueror become the preacher of Dhamma, and how do we know what he thought?

Why it matters: Prelims tests the exact details: Seleucus’s treaty, Megasthenes, Bindusara’s titles, the Kalinga war in Rock Edict XIII, where Ashoka’s name appears, which edict says what. Mains asks about Ashoka’s place in history and how inscriptions are used as sources.


Sources for Mauryan History

TypeSourceWhat it gives
Political treatiseArthashastra (अर्थशास्त्र) of Kautilya (Chanakya / Vishnugupta)Theory and machinery of the state. A manuscript was found by R. Shamasastry in 1905 in the Mysore Oriental Library; he published the text in 1909 and an English translation in 1915. Parts may have been written or revised after the Mauryan age
Greek accountIndica of Megasthenes, ambassador of Seleucus to ChandraguptaThe original is lost; it survives as quotations in later writers such as Strabo, Arrian and Diodorus
DramaMudrarakshasa (मुद्राराक्षस) of Vishakhadatta (Gupta period)Story of Chanakya’s plots against the Nandas
Buddhist textsDipavamsa, Mahavamsa (Sri Lanka), DivyavadanaAshoka’s conversion, the Third Council, missions
Jain textsParishishtaparvan of Hemachandra (12th century)Chandragupta’s Jain end
PuranasVishnu Purana and othersDynastic lists
InscriptionsAshoka’s edicts; the later Junagadh inscription of Rudradaman (c. 150 CE)First-hand royal statements; Mauryan works on the Sudarshana lake

Chandragupta Maurya (चन्द्रगुप्त मौर्य), c. 321–297 BCE

PointDetail
OriginDisputed. Buddhist texts make him a Kshatriya of the Moriya clan of Pipphalivana; some Brahmanical works call him low-born. Greek name Sandrokottos
RiseWith Chanakya, overthrew Dhanananda c. 321 BCE (dates given vary between about 324 and 321 BCE) and took over the north-west after Alexander’s departure
Seleucus NicatorWar c. 305–303 BCE. Seleucus ceded territories in present Afghanistan and Baluchistan (usually listed as Arachosia, Gedrosia, Paropamisadae and possibly Aria) and received 500 war elephants; a marriage alliance was agreed
AmbassadorMegasthenes came to the court at Pataliputra
WestHis governor Pushyagupta, a Vaishya, built the Sudarshana lake in Saurashtra (recorded in the Junagadh inscription of Rudradaman)
EndJain tradition: abdicated, went south with the Jain monk Bhadrabahu, and died by sallekhana (ritual fasting) at Shravanabelagola (Chandragiri hill, Karnataka)
Chandragupta's achievement
He created the first empire covering most of the subcontinent, from Afghanistan to Bengal, joining the Ganga heartland with the north-west.

Bindusara (बिन्दुसार), c. 297–273 BCE

  • Titles: Amitraghata (“slayer of enemies”), rendered Amitrochates by the Greeks.
  • Followed the Ajivika sect, according to tradition.
  • Deimachus came as ambassador from the Seleucid king Antiochus I.
  • A Greek anecdote says Bindusara asked Antiochus for sweet wine, dried figs and a philosopher (sophist); Antiochus sent the first two and replied that Greeks did not sell philosophers.
  • A revolt at Taxila was put down by his son Ashoka (Divyavadana).
  • The empire’s extent into the Deccan by his reign is clear from the fact that Ashoka had to conquer only Kalinga.

Ashoka (अशोक), c. 268–232 BCE

Early life and accession

  • According to Buddhist tradition, he served as viceroy at Ujjain and put down the Taxila revolt during his father’s reign.
  • Buddhist legends speak of a war of succession. His coronation is placed about four years after his accession (c. 269–268 BCE).
  • In his inscriptions he calls himself Devanampiya Piyadasi (देवानांपिय पियदसि), “beloved of the gods, of gracious appearance”. His personal name rarely appears.

The Kalinga War (c. 261 BCE)

PointDetail
DateEighth year after his coronation
SourceMajor Rock Edict XIII
Toll (in the edict’s words)150,000 deported, 100,000 killed, and many times that number died
EffectRemorse; turn from bherighosha (the sound of war drums) to dhammaghosha (the sound of Dhamma); dhamma-vijaya (conquest by righteousness) instead of conquest by arms
The atavikasThe same edict warns the forest peoples that the king, though repentant, still has power to punish them if they do wrong
Kalinga edictsAt Dhauli and Jaugada (Odisha), Rock Edicts XI–XIII are left out and two Separate Kalinga Edicts are inscribed, asking officials to treat the people as the king’s children (“all men are my children”)
A nuance for Mains
Ashoka did not give up the empire, the army or capital punishment after Kalinga. Kalinga was kept, and the atavikas were warned. His change was in method and ideology, not a renunciation of state power.

Ashoka and Buddhism

  • Became a Buddhist lay follower (upasaka) after the war; the Bhabru (Bairat) edict states his faith in the Buddha, Dhamma and Sangha and recommends particular Buddhist texts.
  • Went on a dhammayatra; visited Sambodhi (Bodh Gaya) in his tenth regnal year (Rock Edict VIII) and Lumbini in his twentieth (Rummindei pillar).
  • Third Buddhist Council at Pataliputra, c. 250 BCE, presided over by Moggaliputta Tissa; the Kathavatthu is attributed to it.
  • Missions (per the Sri Lankan chronicles): his son Mahinda (Mahendra) and daughter Sanghamitta (Sanghamitra) to Sri Lanka, where King Devanampiya Tissa accepted Buddhism; Sona and Uttara to Suvarnabhumi (usually placed in lower Myanmar or Southeast Asia); Majjhantika to Kashmir and Gandhara.
  • Rock Edict XIII claims dhamma-vijaya over five Greek kings, including Antiochus II of Syria and Ptolemy II of Egypt, and over the Cholas, Pandyas and Sri Lanka in the south.

Brahmi (left to right)Most of the empire
Kharosthi (right to left)Shahbazgarhi and Mansehra (north-west Pakistan)
Greek and AramaicKandahar and other sites in Afghanistan (the Kandahar rock carries a bilingual Greek–Aramaic inscription)

The language is mostly Prakrit. James Prinsep deciphered Ashokan Brahmi in 1837.

The name “Ashoka”

For decades the edicts were known only as those of “Devanampiya Piyadasi”. In 1915, the gold-mining engineer C. Beadon found the minor rock edict at Maski (Raichur, Karnataka), which reads “Devanampiya Asoka”. This was the first inscription to give his personal name, and it confirmed that Piyadasi was Ashoka. The name also appears in minor rock edicts at Gujarra (Datia, Madhya Pradesh) and at Nittur and Udegolam (Karnataka).

What the major edicts say (high-yield selection)

EdictContent
RE IBan on animal sacrifice and on certain festive gatherings (samaja); fewer animals killed for the royal kitchen
RE IIMedical care for humans and animals; names the Cholas, Pandyas, Satiyaputras, Keralaputras and Tamraparni (Sri Lanka) beyond his borders
RE IIIYuktas, Rajukas and Pradeshikas to tour every five years to teach Dhamma
RE VDhamma Mahamattas appointed in the 13th year after coronation
RE VIIIDhammayatras replace pleasure tours; visit to Sambodhi
RE XIITolerance among sects: whoever honours his own sect by condemning others harms his own
RE XIIIKalinga war; dhamma-vijaya; Greek kings; warning to the atavikas

Other important inscriptions

InscriptionPoint
Rummindei (Lumbini, Nepal) minor pillar edictAshoka visited in his 20th year because the Buddha was born there; made the village free of bali and reduced its share of produce to one-eighth
Schism edict (Sarnath, Sanchi, Allahabad–Kosam)Monks and nuns who split the Sangha are to be expelled
Queen’s edict (Allahabad pillar)Gifts of the second queen Karuvaki, mother of Tivara
Bhabru / Bairat (Rajasthan)Faith in the Buddha, Dhamma and Sangha; recommended Buddhist texts
Delhi-Topra pillarThe only pillar with all seven pillar edicts; moved to Delhi by Firoz Shah Tughlaq
Allahabad pillarAlso carries Samudragupta’s Prayag Prashasti; see Guptas and Vakatakas
Barabar caves (Bihar)Ashoka gifted caves to the Ajivikas; his grandson Dasharatha gave caves in the nearby Nagarjuni hills
Rupnath (near Jabalpur, MP)Minor rock edict; among the find-spots nearest to Chhattisgarh
Chhattisgarh angle
No Ashokan edict has been found inside Chhattisgarh so far. The nearest are in Madhya Pradesh (Rupnath, Gujarra) and Odisha (Dhauli, Jaugada). The Mauryan link with Dakshin Kosala rests on indirect evidence: Brahmi inscriptions of the period in the Jogimara and Sitabenga caves (Ramgarh, Surguja) and Hiuen Tsang’s 7th-century report of a stupa in Kosala attributed to Ashoka. Read Mauryan and Satavahana Period in Chhattisgarh.

Ashoka’s Successors

  • After Ashoka, the empire appears to have been divided; traditions name several successors in different regions.
  • Dasharatha gifted caves in the Nagarjuni hills to the Ajivikas. Samprati is remembered in Jain tradition as a great patron of Jainism.
  • The last Mauryan king, Brihadratha, was assassinated at a review of the army by his general Pushyamitra Shunga, c. 185 BCE, who founded the Shunga dynasty.

Memory Tricks

Mauryan kings: 'C-B-A' backwards alphabet

Chandragupta → Bindusara → Ashoka. The alphabet runs backwards as the empire grows.

  • C: Chanakya, Seleucus (500 elephants), Shravanabelagola
  • B: Bitter enemies slain (Amitraghata), Begged for figs and wine (Deimachus)
  • A: After Kalinga, Ahinsa and Dhamma
Kalinga numbers: '1.5 gone, 1 dead, 8th year'
1.5 lakh deported, 1 lakh killed, in the 8th year after coronation, recorded in RE XIII (8 + 5 = 13).
Where the name Ashoka appears: 'My Great Nephew's Uncle'
Maski · Gujarra · Nittur · Udegolam.

Don’t Confuse

ThisvsThat
Megasthenes — Seleucus’s envoy to ChandraguptavsDeimachus — Antiochus I’s envoy to Bindusara
RE V — Dhamma Mahamattas (13th year)vsRE XIII — Kalinga war (8th year)
RE XII — tolerance among sectsvsRE XIII — dhamma-vijaya over Greek kings
Maski (1915) — first edict with the name AshokavsRummindei — Lumbini visit, one-eighth share
Delhi-Topra — all seven pillar edictsvsAllahabad — Schism and Queen’s edicts + Samudragupta’s Prashasti
Kharosthi — Shahbazgarhi, MansehravsGreek–Aramaic — Kandahar
Barabar — Ashoka’s gifts to AjivikasvsNagarjuni — Dasharatha’s gifts to Ajivikas

Common Mistakes

MCQ traps
  • “Chandragupta fought Alexander.” His war was with Seleucus Nicator, Alexander’s general and successor in the east.
  • “Megasthenes’ Indica survives in full.” It is lost; we have fragments quoted by later Greek and Roman writers.
  • “All Ashokan inscriptions are in Brahmi.” Kharosthi, Greek and Aramaic were also used.
  • “Every Ashokan edict mentions his name.” Most say only Devanampiya Piyadasi; the name appears at Maski, Gujarra, Nittur, Udegolam.
  • “Ashoka abolished the death penalty / disbanded the army.” No edict says so.
  • “The Third Council was held at Vaishali.” It was at Pataliputra, under Moggaliputta Tissa.

Practice

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

Level 1: Foundation

  1. The Greek ambassador at the court of Chandragupta Maurya was ______.
  2. The Kalinga war is described in Major Rock Edict ______.
  3. The Brahmi script of Ashoka’s edicts was deciphered by ______ in ______.
Answers
  1. Megasthenes.
  2. XIII.
  3. James Prinsep, 1837.

Level 2: Prelims MCQs

Q1. Consider the following statements about Ashoka’s inscriptions:

  1. The inscriptions at Shahbazgarhi and Mansehra are in the Kharosthi script.
  2. The Maski edict was the first inscription found that mentions Ashoka by name.
  3. All seven pillar edicts are inscribed on every Ashokan pillar.

Which of the statements given above is/are correct?

  • (a) 1 only
  • (b) 2 and 3 only
  • (c) 1 and 2 only
  • (d) 1, 2 and 3
Answer and explanation
(c) 1 and 2 only. The north-western rock edicts use Kharosthi, and the Maski edict (found 1915) confirmed that Devanampiya Piyadasi was Ashoka. Statement 3 is wrong: only the Delhi-Topra pillar carries all seven pillar edicts.

Q2. Match List I (Ashokan edict) with List II (Subject):

List IList II
A. Rock Edict II1. Appointment of Dhamma Mahamattas
B. Rock Edict V2. Medical care for humans and animals
C. Rock Edict XII3. Kalinga war
D. Rock Edict XIII4. Tolerance among sects
  • (a) A-1, B-2, C-4, D-3
  • (b) A-2, B-1, C-3, D-4
  • (c) A-2, B-4, C-1, D-3
  • (d) A-2, B-1, C-4, D-3
Answer and explanation
(d) A-2, B-1, C-4, D-3. RE II: medical care; RE V: Dhamma Mahamattas in the 13th regnal year; RE XII: respect for all sects; RE XIII: the Kalinga war and dhamma-vijaya.

Q3. The treaty between Chandragupta Maurya and Seleucus Nicator gave Chandragupta territories in present Afghanistan and Baluchistan. What did Seleucus receive in return?

  • (a) 500 war elephants
  • (b) The province of Gandhara
  • (c) A share of the Sudarshana lake revenue
  • (d) The services of Megasthenes
Answer and explanation
(a) 500 war elephants. Megasthenes was Seleucus’s own envoy to the Mauryan court, so (d) reverses the relationship. Gandhara was ceded to the Mauryan side, not received by Seleucus.

Q4. Which one of the following pairs is correctly matched?

  • (a) Bindusara — Mudrarakshasa
  • (b) Chandragupta Maurya — Shravanabelagola
  • (c) Ashoka — Nagarjuni hill caves
  • (d) Dasharatha — Third Buddhist Council
Answer and explanation
(b). Jain tradition says Chandragupta died at Shravanabelagola. Mudrarakshasa is a drama about Chandragupta and Chanakya. The Nagarjuni caves were given by Dasharatha, and the Third Council was held under Ashoka.

Q5. Ashoka’s edict at Rummindei (Lumbini) records that

  • (a) he held the Third Buddhist Council there
  • (b) he reduced the village’s share of produce to one-eighth
  • (c) he ordered the expulsion of schismatic monks
  • (d) he appointed Dhamma Mahamattas there
Answer and explanation
(b). Because the Buddha was born at Lumbini, Ashoka exempted the village from bali and reduced its share of produce to one-eighth. The Schism edict is at Sarnath, Sanchi and Allahabad; the Third Council met at Pataliputra.

Level 3: Mains Answer Writing

Q1. (150–200 words) “Ashoka’s inscriptions are the voice of the king himself.” Discuss their value as a source of history.

Model answer outline
  • Intro: Ashoka’s rock, pillar and cave inscriptions, spread from Kandahar to Karnataka, are the earliest deciphered royal records of India.
  • Body:
    1. First-person statements: Kalinga war (RE XIII), remorse, Dhamma; rare direct access to a ruler’s mind.
    2. Extent of the empire: find-spots map the empire; RE II and XIII name the southern kingdoms and Greek kings beyond it.
    3. Administration: Rajukas, Yuktas, Pradeshikas, Dhamma Mahamattas, provincial princes at Tosali, Ujjain, Taxila, Suvarnagiri.
    4. Society and religion: tolerance (RE XII), welfare works, Buddhist links (Bhabru, Rummindei, Schism edict).
    5. Scripts and languages: Brahmi, Kharosthi, Greek, Aramaic; Prinsep’s decipherment (1837) and the Maski find (1915).
    6. Limits: official propaganda; silence on failures; dating often relative (regnal years).
  • Chhattisgarh angle: no edict found in the state; the Mauryan presence is inferred from Brahmi inscriptions at Ramgarh and Hiuen Tsang’s report.
  • Conclusion: Indispensable, but to be read critically alongside Arthashastra, Megasthenes and archaeology.

Q2. (60 words) What was the significance of the Kalinga war?

Model answer outline
  • Fought in Ashoka’s 8th regnal year (c. 261 BCE); RE XIII records 150,000 deported and 100,000 killed.
  • Completed the empire’s eastern coastline and trade routes.
  • Led to remorse, the policy of dhamma-vijaya and Dhamma Mahamattas.
  • But Kalinga was retained and the atavikas warned: a change of method, not an end of empire.
