Ashoka Embraces Buddhism
Around 260 BCE, the Mauryan emperor Ashoka, ruler of most of the Indian subcontinent, turned toward Buddhism after his campaign against the kingdom of Kalinga on the eastern coast. His conversion matters because it transformed a regional Indian tradition into a faith with reach across Asia, and because he tried to govern according to moral principles rather than conquest alone. The date is approximate, and historians place these events within a few years of it.
Ashoka inherited an empire built by his grandfather Chandragupta Maurya and expanded by his father Bindusara. The Mauryas ruled from their capital at Pataliputra, near modern Patna, through a large army and an elaborate bureaucracy. Ashoka came to the throne around 268 BCE, reportedly after a struggle among Bindusara's sons. Later Buddhist texts describe him as a cruel young ruler, but these accounts are legendary and should be treated cautiously.
Our best evidence for what followed comes from Ashoka's own inscriptions, carved on rocks and polished stone pillars across his realm. In the Thirteenth Major Rock Edict, he describes the conquest of Kalinga and expresses deep remorse over the deaths, deportations, and suffering it caused. The edict gives large figures for the casualties, but these are likely rhetorical and cannot be verified. What is clear is that Ashoka presented the war as a turning point, after which he committed himself to what he called dhamma.
Dhamma, often translated as "moral law" or "righteousness," emphasized nonviolence, tolerance, respect for elders, generosity, and humane treatment of subjects and animals. Scholars debate whether it was identical to Buddhism or a broader ethical code meant to unite a diverse empire. Ashoka does speak of his own devotion to the Buddha and the Buddhist community, yet he also urged respect for other sects. He appointed officials to promote dhamma, built roads, wells, and rest houses, and sent envoys to distant kingdoms, including Hellenistic states in the Mediterranean world, though their impact there is uncertain.
Buddhist tradition credits Ashoka with sponsoring a council at Pataliputra and sending missionaries abroad, including, according to Sri Lankan chronicles, his son Mahinda to Sri Lanka. These accounts are late but widely regarded as reflecting real missionary activity. Buddhism subsequently took root in Sri Lanka and Southeast Asia and later spread along trade routes into Central and East Asia. The Mauryan empire declined within a few decades of Ashoka's death, but his legacy endured. The lion capital from one of his pillars is now India's national emblem, and he remains a symbol of ethical rule.
