What happened
The Mauryan Empire, the first Indian imperial power, rose under Chandragupta Maurya around 322 BCE and by the end of the third century BCE ruled almost all of northern India. Its most famous ruler, Ashoka, grandson of Chandragupta, conquered the eastern kingdom of Kalinga, a campaign World History Encyclopedia says produced a death toll numbering over 100,000. In the aftermath of the carnage, the Library of Congress country study records, Ashoka renounced bloodshed and followed Buddhism. He had edicts on dharma and non-violence chiseled on rocks and stone pillars throughout his empire and sent diplomatic and religious missions abroad, to the rulers of Syria, Macedonia, and Epirus, who learned about India's religious traditions, especially Buddhism.
Why it matters
Ashoka is one of the rare conquerors remembered for the war he refused to fight again rather than the ones he won, and his patronage turned Buddhism from a regional teaching into a religion that spread across Asia. The Mauryan state set the enduring idea of a single Indian empire.
How we know
Ashoka's own edicts survive carved in stone across the subcontinent, giving a first-person imperial voice unusual for the ancient world, and the Mauryan state is described in later Greek and Indian accounts.
