In this guide
Around 321 BCE, Chandragupta Maurya came to power in Magadha. Within two generations, his dynasty ruled from Afghanistan to Karnataka. Its most famous king, Ashoka, is remembered not for his conquests but for renouncing them — and for leaving the earliest large body of royal inscriptions in India, in which he speaks directly to his subjects.
For UPSC, the Mauryas offer Prelims material on sources, edicts and administration, and a Mains-worthy theme in Ashoka's Dhamma: a rare example of a ruler trying to govern through a public moral code.
How we know about the Mauryas
| Source | Type | What it tells us |
|---|---|---|
| Arthashastra, attributed to Kautilya | Treatise on statecraft | Administration, economy, espionage, law — though its date and authorship are debated |
| Indica by Megasthenes | Account by a Greek ambassador at Chandragupta's court | Survives only in quotations by later writers; describes Pataliputra and society |
| Ashokan inscriptions | Edicts on rocks and pillars | Ashoka's policies and ideas in his own words |
| Buddhist and Jain texts | Religious literature | Traditions about Chandragupta and Ashoka, sometimes legendary |
| Mudrarakshasa by Vishakhadatta | Later Sanskrit play | Dramatised account of Chandragupta and Chanakya |
| Archaeology | Sites, pillars, sculpture | Pataliputra, the pillars, the Sarnath capital |
The rulers
Chandragupta Maurya (c. 321–297 BCE) overthrew the Nanda dynasty, reportedly with the help of Chanakya (Kautilya), and fought the Greek successor of Alexander, Seleucus Nicator. A treaty followed; Megasthenes came to Chandragupta's court as Seleucus's envoy. Jain tradition holds that Chandragupta later became a Jain and died at Shravanabelagola.
Bindusara (c. 297–273 BCE) extended the empire southward.
Ashoka (c. 268–232 BCE) inherited a vast empire. The decisive event of his reign was the conquest of Kalinga (roughly present-day Odisha).
Kalinga and its aftermath
In his Thirteenth Major Rock Edict, Ashoka describes the Kalinga war: a large number of people were killed, deported or died of its effects. He expresses remorse — an extraordinary statement for a king — and declares that true conquest is conquest by Dhamma.
Kalinga did not end Ashoka's rule as a powerful emperor. He did not disband his army, and the edicts warn forest peoples that the king has power as well as compassion. But after Kalinga, Ashoka's public policy changed direction.
What was Dhamma?
Dhamma is the Prakrit form of the Sanskrit dharma. Ashoka's Dhamma was not Buddhism, although Ashoka was personally a Buddhist. It was a set of ethical principles addressed to all his subjects, whatever their faith.
Its core ideas, drawn from the edicts:
- Tolerance — respect for all sects; restraint in speech about one's own and others' beliefs.
- Non-violence — restrictions on animal sacrifice and killing; reduced royal hunting.
- Social ethics — obedience to parents, respect for elders and teachers, generosity to Brahmanas and Shramanas, kindness to slaves and servants.
- Welfare — hospitals for humans and animals, wells, rest houses, shade trees along roads.
To spread Dhamma, Ashoka appointed Dhamma Mahamattas — officials charged with promoting Dhamma and the welfare of people of all sects — and himself undertook Dhamma tours (dhammayatras).
Why did he do it? Historians offer several interpretations, and a good answer presents more than one:
- a genuine moral transformation after Kalinga;
- a policy of social cohesion for a vast, diverse empire — a set of shared values that could bind very different communities, as argued by Romila Thapar;
- a way to reduce the tensions between different religious groups and between rulers and subjects.
The edicts
| Type | Content |
|---|---|
| Major Rock Edicts (14) | Principles of Dhamma, the Kalinga war (XIII), welfare measures, relations with neighbouring kingdoms |
| Minor Rock Edicts | Ashoka's personal commitment to Buddhism; some mention him by name |
| Pillar Edicts (7) | Dhamma, administration and welfare; the famous Delhi–Topra pillar carries all seven |
| Minor Pillar Edicts | Include the schism edict and records of pilgrimage, such as at Lumbini |
Languages and scripts: most edicts are in Prakrit, in the Brahmi script. In the north-west, Kharosthi was used (Shahbazgarhi, Mansehra). At Kandahar, inscriptions appear in Greek and Aramaic.
Decipherment: James Prinsep deciphered Brahmi in 1837. For a long time the "Devanampiya Piyadasi" of the edicts was not certainly identified with Ashoka; the name Ashoka appears in a few minor rock edicts, famously at Maski.
Administration
The Mauryan state is often described as highly centralised, based on the Arthashastra and Megasthenes:
- The king at the centre, advised by a council of ministers (mantriparishad).
- The empire divided into provinces, often governed by princes, with important centres at Taxila, Ujjain, Tosali and Suvarnagiri.
- A large bureaucracy with superintendents (adhyakshas) for trade, agriculture, mines and other areas.
- An extensive network of spies.
- Megasthenes describes the city administration of Pataliputra by committees.
Recent historians caution that the degree of centralisation may be overstated: the core regions were closely administered, while distant regions and forest areas were probably governed more loosely.
Decline
The empire weakened within fifty years of Ashoka's death. Around 185 BCE, the last Mauryan king, Brihadratha, was killed by his general Pushyamitra Shunga, who founded the Shunga dynasty.
Explanations include weak successors, the economic burden of a large army and bureaucracy, the difficulty of holding together such a vast territory, and the partition of the empire among Ashoka's successors. The older view that Ashoka's pacifism weakened the empire is not widely accepted; the army remained, and the decline was gradual.
The Mauryan legacy
- The first political unification of most of the subcontinent.
- A model of an ethical, welfare-oriented state, echoed centuries later in the thinking of the Constitution's framers.
- The spread of Buddhism beyond India — missions associated with Ashoka's reign, including to Sri Lanka through Mahinda and Sanghamitta.
- Monumental art: the polished pillars and animal capitals, the Sarnath lion capital.
Practice questions
- Prelims-type: In which script were Ashoka's edicts in the north-west written? Which edict describes the Kalinga war?
- Mains-type (150 words): "Ashoka's Dhamma was a policy of social cohesion rather than a religion." Examine.
- Mains-type (250 words): Evaluate the sources for the history of the Mauryan period. What are their limitations?
