Primary Sources for the Maurya Empire
Three texts form the bedrock of Mauryan historiography. Kautilya's Arthashastra — a treatise on statecraft, economics, and military strategy — gives us the empire from the inside. Vishakhadatta's Mudrarakshasa (a later Sanskrit play, c. 4th–5th century CE) dramatises Chandragupta's rise and Kautilya's political manoeuvres. Megasthenes' Indica, written by the Seleucid ambassador to Pataliputra, offers a Greek outsider's perspective.
Beyond these three, Buddhist texts (Mahavamsa, Dipavamsa) preserve the Ashoka tradition, while Jain texts (Parishishtaparvan by Hemachandra) record Chandragupta's abdication story. Plutarch's Life of Alexander provides the famous passage identifying "Sandrokottos" as the young man who met Alexander — the synchronism that anchors Indian chronology to the Greek calendar.
The identification of Sandrokottos in Greek sources with Chandragupta in Indian sources — first made by William Jones in 1793 — is the single most important synchronism in ancient Indian history. It allows Indian regnal dates to be fixed to the absolute Greek calendar.
Alexander in India (326–323 BCE)
Alexander crossed the Hindu Kush and entered the subcontinent in 326 BCE. His most significant Indian engagement was the Battle of the Hydaspes (Jhelum River) against King Porus (Paurava). Despite a hard-fought victory — Porus's war elephants caused serious Macedonian casualties — Alexander was so impressed by his adversary's bearing that he reinstated Porus as a subordinate ruler.
The army mutiny at the Beas (Hyphasis) is significant: the soldiers had heard of the vast Nanda army beyond the river and refused to continue. This retreat left a power vacuum in northwest India that Chandragupta would exploit within a few years. Plutarch records that years later, Chandragupta told his associates he had actually met Alexander, and that Alexander's manner of marching had been unwise — a retrospective critique that implies close observation.
The Nanda Dynasty and Its Overthrow
The Nanda dynasty, founded by Mahapadma Nanda (c. 345 BCE), was the first non-Kshatriya (likely Shudra) imperial family in Indian history — a point noted with derision by Brahmin sources. The dynasty is celebrated in Greek sources for its immense military strength: 200,000 infantry, 80,000 cavalry, 8,000 chariots, and 6,000 war elephants (Curtius). The final king, Dhana Nanda, was reportedly tyrannical and miserly, storing his enormous treasury beneath the Ganges riverbed according to later tradition.
Kautilya's strategic doctrine — preserved in the Arthashastra — prescribes a "periphery-first" approach: conquer the distant frontier states first to isolate the core before attacking the centre. Chandragupta is said to have first built a power base in the northwest (taking advantage of the post-Alexander vacuum), then advanced on Magadha from the periphery inward. Dhana Nanda was killed, and Chandragupta was crowned at Pataliputra around 322–321 BCE.
For a parallel narrative on the rival powers Chandragupta faced in the east, see the treatment of the Sixteen Mahajanapadas and Magadha's rise, which charts how Magadha's iron resources and geographical advantages made it the dominant power that the Mauryas then inherited.
The Seleucus Treaty (305–303 BCE)
After Alexander's death, his general Seleucus Nicator inherited the eastern satrapies and launched a campaign to recover the Indian territories. Around 305–303 BCE, Chandragupta defeated Seleucus decisively. The resulting treaty is one of UPSC's most tested passages of ancient history.
Chandragupta gave Seleucus 500 war elephants — NOT horses. These elephants proved decisive at the Battle of Ipsus (301 BCE), helping Seleucus's coalition defeat Antigonus Monophthalmus. The elephant trap is set repeatedly in UPSC questions: any statement saying "horses" is automatically false.
In exchange, Seleucus ceded four territories:
- Arachosia (modern Kandahar region, Afghanistan)
- Gedrosia (modern Balochistan)
- Paropanisadai (modern Kabul valley / Hindu Kush foothills)
- Aria (modern Herat region, western Afghanistan)
The two sides also agreed to epigamia — the right of inter-marriage between Greeks and Indians. As his resident ambassador (duta) to Pataliputra, Seleucus sent Megasthenes, whose reports survive as the Indica.
Megasthenes and the Indica
Megasthenes served as Seleucid ambassador at Pataliputra (Patna) for an extended period during Chandragupta's reign. His Indica is lost as an independent work but survives in lengthy fragments quoted by later Greek and Roman authors — Diodorus Siculus, Strabo, Arrian, and Pliny the Elder.
| Feature Described by Megasthenes | Detail |
|---|---|
| Pataliputra's fortifications | Wooden palisade (not stone), 570 towers, 64 gates |
| Army strength (reported) | 600,000 infantry, 30,000 cavalry, 9,000 elephants |
| Social observation | "No slavery in India" — widely quoted but probably reflects unfamiliarity with Indian forms of unfree labour |
| Agriculture | Land divided by royal surveyors; rivers irrigate fields; two harvests per year |
| Seven castes | Philosophers, farmers, herdsmen, artisans, soldiers, overseers, councillors — differs from varna system |
| Status of original text | LOST — survives only in fragments in later authors |
The description of the wooden palisade at Pataliputra was later confirmed archaeologically by D. B. Spooner's excavations at Bulandibagh (1912–15), which unearthed carbonised timber fragments of the palisade. This is one of the relatively rare cases where ancient literary evidence and archaeology align directly for this period.
The Arthashastra: Structure and Significance
The Arthashastra ("Science of Material Gain" or "Treatise on Statecraft") is composed of 15 adhikaranas (books) covering the full spectrum of royal administration. R. Shamasastry's 1909 publication of the first English translation revealed a text far more sophisticated than anything previously known from ancient India.
The text covers: training of the king, duties of ministers, conduct of officers, revenue collection, fortification of cities, army organisation, conduct of war, treatment of conquered territories, and an elaborate spy system (Guptacharas). It predates Machiavelli by nearly 1,800 years and is often compared to it — though the Arthashastra is far more comprehensive in scope.
The comparison between Kautilya and other ancient political thinkers is explored in the broader treatment of Maurya administration and economy, which covers the Arthashastra's departmental system (Adhyakshas) and revenue mechanisms in operational detail.
Saptanga Theory and the Mandala
Saptanga — Seven Pillars of the State
Kautilya's Saptanga theory describes seven interdependent elements that constitute a viable state:
| # | Sanskrit Term | Meaning |
|---|---|---|
| 1 | Swami | The sovereign/king — the central element |
| 2 | Amatya | Ministers and high officials |
| 3 | Janapada | Territory with its population |
| 4 | Durga | The fortified capital city |
| 5 | Kosha | Treasury |
| 6 | Danda | Army / coercive force |
| 7 | Mitra | Allies |
Mandala Theory — the Circle of Kings
The Mandala (circle) theory describes the geopolitical relationships between states arranged in concentric rings around a conquering king (vijigishu):
Beyond the inner ring of enemies and friends, Kautilya identifies further concentric rings: the ari-mitra (enemy's ally), the mitra-mitra (ally's ally), and so on. The sixth strategy (Shadgunya or Shatkarma) lists the six foreign policy tools: sandhi (peace), vigraha (war), asana (neutrality), yana (march/mobilisation), samshraya (seeking protection), and dvaidhibhava (dual policy — peace with one, war with another).
Bindusara (c. 297–272 BCE)
Chandragupta's son Bindusara ruled for approximately 25 years. His Greek name, preserved as Amitrachates, is a transliteration of the Sanskrit Amitraghata — "Destroyer of Enemies" or "Slayer of Foes." He received a Seleucid ambassador named Deimachus, who left observations about India (also mostly lost). Bindusara reportedly requested that Seleucus send him sweet wine, dried figs, and a Greek philosopher — Seleucus replied he could send the wine and figs but that Greek philosophers were not for export.
Bindusara is believed to have extended Mauryan control southward into the Deccan. He is associated with the Ajivika sect. His accession was not without struggle — later tradition (Divyavadana) records that Ashoka was the governor of Ujjain and Taxila before his father's death.
Jain Tradition: Chandragupta's Abdication
Jain sources, particularly Hemachandra's Parishishtaparvan (12th century CE), record that towards the end of his reign Chandragupta was attracted to Jainism under the influence of the monk Bhadrabahu. Facing a great famine in Magadha, Bhadrabahu led a group of Jain monks southward to Shravanabelagola in Karnataka. Chandragupta, having abdicated in favour of Bindusara, accompanied this migration.
At Shravanabelagola, on Chandragiri Hill (the smaller of the two hills; the larger, Vindhyagiri, holds the famous Gomateshvara statue), Chandragupta is said to have practised sallekhana — the Jain practice of voluntary fasting unto death. This tradition is preserved in inscriptions at the site.
Chandragupta's abdication is associated with Shravanabelagola, Karnataka — specifically Chandragiri Hill. The larger Vindhyagiri Hill at the same site holds the massive 10th-century Gomateshvara (Bahubali) statue, which is a separate topic.
With reference to the history of ancient India, which of the following statements is/are correct?
1. Chandragupta Maurya's expansion of his empire was stopped by Seleucus at the Hindukush.
2. Chandragupta Maurya gave 500 war elephants to Seleucus under the peace treaty.
3. Chandragupta Maurya acquired the territories of Arachosia and Gedrosia under the peace treaty with Seleucus.
Statement 1: Chandragupta defeated Seleucus — he was not stopped. But the peace treaty was concluded after Seleucus attempted to push beyond the Hindu Kush (Statement 1 is FALSE as written — Chandragupta was not stopped). Statement 2: Chandragupta gave 500 elephants — this is CORRECT but Statement 1 is false. Statement 3: Arachosia and Gedrosia were indeed ceded — CORRECT. The answer pattern depends on how each statement is worded in the actual exam. The key testable fact: 500 elephants (not horses), and the four territories ceded (Arachosia, Gedrosia, Paropanisadai, Aria).
With reference to the 'Arthashastra' of Kautilya, which of the following statements is/are correct?
1. It is divided into 15 adhikaranas.
2. According to Arthashastra, the neighbour of the vijigishu (conqueror) is a natural ally.
3. It discusses in detail the duties of a king and his ministers.
Statement 1: CORRECT — 15 adhikaranas. Statement 2: FALSE — this is the classic Mandala trap. The neighbour is the natural enemy (ari), not an ally. The mitra (ally) is the neighbour's neighbour. Statement 2 is always false in any correctly worded UPSC question. Statement 3: CORRECT — the Arthashastra extensively discusses royal duties and the Mantri-Parishad.
Frequently Asked Questions
What did Chandragupta give Seleucus in the 305 BCE treaty?
500 war elephants — NOT horses. In exchange, Seleucus ceded Arachosia, Gedrosia, Paropanisadai, and Aria. The elephants proved decisive at the Battle of Ipsus (301 BCE).
Who is Megasthenes and why is his work important?
Megasthenes was the Seleucid ambassador at Pataliputra during Chandragupta's reign. His Indica is the most important Greek source on Maurya India. Though the original is lost, it survives in fragments quoted by Diodorus, Strabo, Arrian, and Pliny.
What is the Mandala Theory and why does it confuse UPSC aspirants?
The Mandala Theory says the immediate neighbour is a natural enemy (ari) and the neighbour's neighbour is a natural friend (mitra). UPSC frequently sets a statement saying "the neighbour is a natural ally" — this is always FALSE.
What are the 15 adhikaranas of the Arthashastra?
The 15 books cover: training of the prince, duties of superintendents, concerning departments of government, removal of thorns (criminal law), conduct of courtiers, source of sovereign states, conduct during emergencies, concerning the subject of an invading conqueror, work of an invader, relating to war, concerning the practices of corporations, concerning secret conduct, strategic means to capture a fort, secret means, plan for a conqueror. The number 15 is directly tested by UPSC.
Where did Chandragupta Maurya die, according to Jain tradition?
At Shravanabelagola, Karnataka, on Chandragiri Hill, through the practice of sallekhana (voluntary fasting unto death) under the guidance of the Jain monk Bhadrabahu.
