By the time work began on Major Rock Edict 13, often written with the Roman numeral XIII, Ashoka had already won the war it describes. What the edict does next is unusual for an ancient ruler: it dwells on the cost of the victory. In S. Dhammika's translation of Rock Edict XIII[4], Ashoka reports 100,000 killed, 150,000 deported, and further deaths from other causes after the conquest of Kalinga, fought around 261 BCE. The edict expresses remorse; its figures remain a royal claim, not an independently verified count. Few inscriptions from the ancient world are this self-critical. That is part of why historians value the edicts so highly as a source for early India (NCERT, section 3.1, p. 32[1]), while remembering that they are also carefully managed royal statements.
What does Ashoka's Rock Edict 13 say?
The edict opens by dating the war: Ashoka conquered Kalinga eight years after his coronation, which is how historians arrive at c. 261 BCE. After giving the toll, he says the conquest turned him towards dhamma and that he feels deep remorse, because conquering a people means killing, death and deportation, and the suffering falls even on the pious and on those who took no part in the fighting. He would now grieve, he says, if even a hundredth or a thousandth of those who suffered in Kalinga were to suffer the same way. The edict is not only penitent. It tells the forest peoples inside the empire that, for all his remorse, the king still has the power to punish them. Its central claim is that conquest by dhamma is the best conquest, and it closes by explaining why it was written: so that Ashoka's sons and great-grandsons would not think of new conquests, or, if they made them, would prefer patience and light punishment (Rock Edict XIII, translated by S. Dhammika[4]).
Why is Rock Edict 13 missing in Kalinga?
Rock Edict 13 survives at sites across Ashoka's empire, but is absent at Dhauli and Jaugada in Kalinga. The separate Kalinga edicts address local officials: Kalinga Rock Edict I, translated by S. Dhammika[4], calls for impartial justice and describes the population as the king's children. NCERT, section 7.3, p. 48[1], asks whether the absence of the remorse inscription in the conquered region reflects the sensitivity of the recent conquest. That reading rests on where the inscriptions were placed; Ashoka never states the motive himself.
Dhamma as a program of government
After Kalinga, Ashoka's edicts describe a turn toward what he called dhamma, a broad term for a code of civic ethics, not a specific creed (Encyclopaedia Britannica, "Ashoka"[5]). Rock Edict II and Pillar Edict VII, translated by S. Dhammika[4], describe medical care for humans and animals, roadside wells and trees, and rest houses. Other edicts restrict the slaughter of certain species, discourage elaborate and wasteful ceremonies, and urge respect toward parents, elders, and ascetics of every religious community, not only Buddhists (Rock Edicts I, IX, XI and XII, in S. Dhammika's translation[4]). Historians disagree over how much of this was ethical conviction and how much a ruler's search for a shared civic vocabulary across a vast, religiously diverse empire (Romila Thapar, Aśoka and the Decline of the Mauryas[2]). The edicts suggest it was most likely both.
Written in four scripts, then forgotten for two thousand years
Carrying that message across such a large empire meant writing it differently depending on where it would be read. Most edicts used Prakrit and the Brahmi script; some northwestern inscriptions used Kharosthi, while inscriptions in Afghanistan used Greek and Aramaic (NCERT, “Languages and scripts,” p. 32[1]). Over the following centuries Brahmi evolved into later scripts and Kharosthi fell out of use, until no one in India could read the Ashokan letterforms, and Ashoka's name faded from active memory in India for nearly two millennia (Richard Salomon, Indian Epigraphy[3]). In 1837 the British scholar James Prinsep deciphered Brahmi, using the short, repetitive donor inscriptions on the railings and gateways at Sanchi to work out its alphabet. What he found was a ruler who referred to himself not as "Ashoka" but as Devanampiya Piyadasi, "Beloved of the Gods, of Gracious Mien". Scholars matched that title against the Sri Lankan Buddhist chronicles, the Dipavamsa and Mahavamsa, which call Ashoka Piyadasi, and identified the two as the same person (NCERT, "Prinsep and Piyadassi," pp. 28–29[1]). The identification was settled in 1915, when a minor rock edict found at Maski in Karnataka named its author as "Devanampiya Asoka" (S. Dhammika, The Edicts of King Asoka, introduction[4]).
Missionaries beyond the empire
Buddhist tradition, recorded mainly in those same Sri Lankan chronicles rather than in the edicts themselves, credits Ashoka with convening a Third Buddhist Council at Pataliputra to settle disputes within the monastic community, after which missions were dispatched outward to spread the dhamma. The best-documented of these went to Sri Lanka, led by Mahinda, traditionally described as Ashoka's son. He is said to have converted King Devanampiya Tissa at Mihintale, near Anuradhapura, and tradition dates Theravada Buddhism on the island from that conversion (Encyclopaedia Britannica, "Ashoka"[5]). At home, Magadha stayed a heartland of Buddhist scholarship long after the Mauryas: Nalanda, its great monastic university, was founded there in the fifth century CE. Separately, Rock Edict XIII, translated by S. Dhammika[4], claims that conquest through dhamma reached the realms of Hellenistic kings, naming Antiochos and Ptolemy among others, as well as the Cholas and Pandyas of the Tamil south; it also mentions places his envoys had not visited. The inscription alone cannot establish what effect these contacts had, because it is Ashoka's own account of his reign. The Cholas it names were the early Tamil rulers whose name the imperial Chola dynasty of Thanjavur revived more than a thousand years later.
Ashoka died around 232 BCE, and no later Mauryan ruler continued his inscription program at anything like the same scale. The empire unraveled within decades (Romila Thapar, Aśoka and the Decline of the Mauryas[2]). The inscriptions outlasted it, and no other Indian ruler of the period left anything like them: a government explaining itself in its own words, in more than one language and to more than one audience, and admitting at least once that it had gotten something terribly wrong.
