Defeated Dhana Nanda (~321 BC) with guerrilla tactics; took control of Pataliputra
→ Seleucid War (~305 BC): Defeated Seleucus Nicator (Alexander's successor who wanted India back); Treaty: Seleucus gave Afghanistan, Balochistan, parts of Persia to Chandragupta; India sent 500 war elephants in return; Megasthenes came to Pataliputra as Seleucid ambassador

Kalinga War — The Turning Point

Year: 261 BC — 9th year of Ashoka's reign
Scale: ~1,00,000 soldiers killed; ~1,50,000 taken captive; many more died from wounds, disease
Ashoka's reaction: Horrified by the suffering; his famous Rock Edict XIII records his remorse: "Even those who escape, suffer because of the loss of friends and family"
Consequence: Converted to Buddhism (under teacher Upagupta); gave up conquest of war (Bherighosha) for conquest of Dhamma (Dhammaghosha)
Kalinga = modern Odisha

Dhamma Policy

Ashoka's Dhamma (Pali for Dharma) was NOT just Buddhism — it was a universal secular code of ethics:

Respect for all religions and sects
Non-violence (reduction of animal slaughter; no eating of meat in royal kitchens)
Obedience to parents, elders, teachers
Truthfulness and compassion
Lack of extravagance and cruelty

Spread through: Dhamma Mahamattas — special officials touring the empire to spread Dhamma; inspection tours by Ashoka himself
