Ashoka the Great: From Warrior to Peaceful Emperor
By Gaurav Thapa. Updated 31 August 2026. Checked against the Ashokan edicts and the books listed at the end.
Ashoka the Great history, as we know it, begins in 1837 with a British mint official in Calcutta. James Prinsep worked out how to read Brahmi, a script nobody had read for about a thousand years, and the inscriptions it unlocked turned out to be the words of one man. Carved on rocks and polished sandstone pillars from Kandahar to Karnataka, they spoke for a king who called himself Devanampiya Piyadasi, “Beloved of the Gods”. He had ruled most of the subcontinent in the third century BCE, conquered a neighbouring kingdom at terrible cost, and then apologised for it in public.
For decades nobody could prove who Piyadasi was. The Sri Lankan chronicles used the same title for a king they called Asoka, but the proof came only in 1915, when a gold-prospecting engineer noticed an inscription at Maski, in Karnataka, that used the name Asoka itself. The forgotten emperor had, in effect, signed his work.

How Ashoka became emperor
Ashoka was not the obvious heir. The Ashokavadana, a cycle of Buddhist legends written some four centuries after his death, remembers him as one of Bindusara’s many sons: rough-skinned, disliked by his father, and sent off to govern distant provinces, first Taxila in the northwest and later Ujjain in Malwa.
When Bindusara died around 272 BCE, the succession turned ugly. The Sri Lankan chronicles claim Ashoka killed his brothers (ninety-nine of them, in their telling, which says a lot about the chroniclers) and was formally consecrated only about four years later, around 268 BCE. That gap between accession and coronation is one of the few details in the legends that historians take fairly seriously, because it suggests a contested start.
The same texts describe the young king as “Chandashoka”, Ashoka the Cruel, who kept a torture house in Pataliputra. Most historians treat this with suspicion. The stories were written by monks with a sermon to preach, and the darker the sinner, the brighter the conversion. Romila Thapar, whose 1961 study is still the standard work on the reign, reads them as moral literature rather than biography.
Take the legend away and the hard evidence is simpler. Ashoka inherited the huge, tightly run state that his grandfather Chandragupta had built with Chanakya (we cover that in our piece on the rise of the Mauryan Empire). In the eighth year after his consecration, he took it to war.
Why the Kalinga War changed Ashoka
Kalinga, roughly modern Odisha, was a prosperous coastal kingdom that had stayed outside Mauryan control. Around 261 BCE Ashoka conquered it. The war is famous less for the victory than for how we know about it. No court poet celebrated the triumph. What survives is the conqueror’s own confession, cut into rock in Major Rock Edict XIII:
“One hundred and fifty thousand people were deported, one hundred thousand were killed, and many times that number perished… After the Kalingas had been conquered, Beloved-of-the-Gods came to feel a strong inclination towards the dhamma, a love for the dhamma and for instruction in dhamma. Now Beloved-of-the-Gods feels deep remorse for having conquered the Kalingas.”
Major Rock Edict XIII, translated by Ven. S. Dhammika
Should you take the numbers literally? Probably not. Ancient inscriptions round freely, and “many times that number” is rhetoric, not a count. The remorse is a different matter. No other ruler of the ancient world is known to have left a public apology for a war he won.
The edict also speaks directly to Ashoka’s sons and grandsons, asking them not to think new conquests worth having. The only conquest worth the name, it says, is “conquest by dhamma”. The campaign itself, and the argument over how big it really was, are covered in our separate article on the Kalinga War.
What Ashoka meant by “dhamma”
The one-line version you will find in most guidebooks is that Ashoka “converted to Buddhism and gave up violence”. His own inscriptions complicate both halves of that sentence.
Read the edicts and you will find almost no Buddhist doctrine. There are no Four Noble Truths and no nirvana. The dhamma Ashoka preached to his subjects was closer to a code of public decency: obey your parents, be generous to friends and ascetics, spend modestly, speak carefully, and treat servants and animals kindly.
Above all, respect other people’s beliefs. Rock Edict XII says all sects “deserve reverence for one reason or another”, and warns that anyone who praises his own sect too loudly ends up harming it. For a UPSC answer on religious tolerance in ancient India, this is the edict to quote.
Privately, Ashoka was a committed Buddhist layman. The Minor Rock Edicts trace his growing involvement with the sangha. Buddhist tradition credits him with supporting the Third Buddhist Council at Pataliputra and sending missionaries abroad, among them his son Mahinda and daughter Sanghamitta, who the chronicles say took Buddhism to Sri Lanka. Whatever the exact details of that mission, this is roughly when Buddhism began to spread well beyond India.
He did not become a pacifist in any modern sense. The army stayed. Rock Edict XIII carries a blunt notice to the forest tribes that the king, remorseful or not, still has the power to punish. What changed was what that power was said to be for.
Governing by inscription: welfare carved in stone
The edicts double as a government report card, and parts of it still read well:
- Medical care: Rock Edict II records medical treatment for people and animals, and the planting of medicinal herbs across the empire and even in neighbouring kingdoms.
- Roads and rest: Pillar Edict VII mentions banyan trees planted for shade, mango groves, wells at regular intervals and rest houses for travellers.
- A new kind of official: the dhamma-mahamattas, officers Ashoka created to promote good conduct and look after prisoners, the elderly and religious communities (Rock Edict V).
- Animal welfare: Pillar Edict V lists protected species and restricts forest burning. Rock Edict I notes that the royal kitchen, which once killed hundreds of animals a day, was down to two peacocks and a deer, “and the deer not regularly”.
Whether all of this happened as described, nobody can now check. An inscription is a press release, not an audit. Still, a state that chose to brag about planting shade trees rather than counting enemy dead was trying something new in the ancient world.
Where the edicts are, and why India forgot them
Ashokan inscriptions survive at more than thirty sites across India, Nepal, Pakistan and Afghanistan. Most are in Prakrit written in Brahmi. The northwestern ones use Kharosthi, and at Kandahar there is a bilingual edict in Greek and Aramaic for the frontier’s Hellenistic population.
Then Brahmi fell out of use, and with it the ability to read any of them. People saw the pillars for centuries without knowing whose words they carried. Firoz Shah Tughlaq liked one enough in the 1350s to haul it to Delhi on a specially built forty-two-wheel cart, but nobody at his court could read it. Prinsep’s decipherment in 1837 gave the emperor his voice back. The Maski edict of 1915 gave him back his name.
What happened to the Mauryan Empire after Ashoka
Ashoka died around 232 BCE, after some thirty-six years on the throne. The empire did not last long without him. Within half a century it had shrunk to its heartland, and the last Mauryan emperor was overthrown by his own general around 185 BCE. North India would not be held together on a similar scale again until the Guptas in the fourth century CE, a period we cover in our article on the Gupta Empire.
Ashoka’s memory survived mainly outside India: in the Sri Lankan chronicles, in the accounts of Chinese pilgrims who came looking for his monuments, and in legends told across Buddhist Asia. India itself, having lost the script he wrote in, largely forgot him.
The rediscovery made him a founding figure for a new nation. The Ashoka Chakra, the dhamma wheel from the Sarnath capital, went into the centre of the national flag in 1947, and the Lion Capital became the state emblem of the Republic. H.G. Wells had already written the line every quiz book repeats: among the tens of thousands of monarchs in history, “the name of Asoka shines, and shines almost alone, a star.”
If you want to see the edicts for yourself, Dhauli near Bhubaneswar is the one to start with. It sits close to the old Kalinga battlefield, and it is one of the places where Ashoka left out Rock Edict XIII, the confession, and carved two special edicts addressed to his officials instead. Historians still argue about why he chose not to publish his apology in the very region he had conquered.

Frequently Asked Questions
Did Ashoka make Buddhism India’s state religion?
No. He supported the sangha personally and sent Buddhist missions abroad, but the dhamma of his public inscriptions is non-sectarian. Rock Edict XII asks for respect for all sects, and Pillar Edict VII names Brahmins, Ajivikas and Jains among the communities his officers were to look after.
How do we know the edicts are really Ashoka’s words?
Most inscriptions use the title Devanampiya Piyadasi. Minor edicts at Maski and Gujarra add the personal name Asoka, and the Sri Lankan chronicles use both names for the same king, so the identification has been settled since 1915.
Where can I see Ashokan edicts today?
Dhauli and Jaugada in Odisha, Girnar in Gujarat, Sarnath near Varanasi, and the two pillars Firoz Shah Tughlaq brought to Delhi in the 1350s. The Lion Capital itself is in the Sarnath Museum.
What language are the Ashokan edicts written in?
Mostly Prakrit, in the Brahmi script. Edicts in the northwest use the Kharosthi script, and the Kandahar inscriptions are in Greek and Aramaic.
