See it on the History map →What happened
Grandson of Chandragupta, Ashoka conquered Kalinga, on India's east coast, around 261 BC. His own inscription says about 100,000 were killed and 150,000 deported, and that he felt deep remorse. He turned to Buddhism and promoted dhamma: non-violence, tolerance of all faiths, kindness to animals and care for the poor. He dug wells, built rest houses, provided medical care for people and animals, and sent envoys to Sri Lanka and the Greek kingdoms.
Why it matters
His patronage helped turn Buddhism from a regional sect into a missionary religion that would reach much of Asia. His wheel is on India's flag.
Legacy and how we know
About 33 edicts, mostly in Prakrit in the Brahmi script that James Prinsep deciphered in 1837, some in Greek and Aramaic, plus later Buddhist chronicles that add legends.
Still debated
Some historians read his remorse partly as political messaging, and how strictly dhamma was enforced in practice is unclear.

▸Ashoka the Great spread the teachings of The Buddha (Siddhartha Gautama)Well documented
The connection
After the Kalinga war, Ashoka became a lay Buddhist and used imperial resources to promote the faith. He built stupas (domed shrines holding relics), supported monasteries, reportedly hosted a council of monks, and sent missions abroad. By tradition his son Mahinda carried Buddhism to Sri Lanka, from where it later spread to Southeast Asia.
When and how
The Maurya Empire, c. 260–232 BC; missions to Sri Lanka, Gandhara in the northwest and the lands beyond.
How we know
Ashoka's own edicts describe his conversion and envoys; Sri Lankan chronicles, the Dipavamsa and Mahavamsa, record Mahinda's mission with legendary embellishment.
Debates and open questions
Whether the 'Third Council' and the missions happened as the chronicles say is debated; Greek kingdoms show little sign of receiving them.
▸Ashoka the Great ruled Maurya EmpireWell documented
The connection
Ashoka, Chandragupta's grandson, took the throne around 268 BC after, by legend, a bloody succession fight. He ruled about 36 years, completing the empire's expansion with Kalinga and then governing by dhamma, with special officers to promote morality. After his death the empire weakened; it ended about 185 BC, when a general killed the last Maurya king.
When and how
From the capital Pataliputra (modern Patna), c. 268–232 BC.
How we know
His edicts call him Devanampiya Piyadasi, 'Beloved of the Gods'; an edict found at Maski in 1915 uses the name Ashoka, confirming the identity.
Debates and open questions
How much his non-violent policy weakened the army and hastened the empire's fall is debated.
