Ashoka was the third king of the Mauryan Dynasty who ruled from 272-232 BCE. After his bloody conquest of the Kalinga kingdom, Ashoka was deeply affected by the violence and suffering of war and converted to Buddhism. He promoted Buddhist teachings through edicts, building monuments, and sending missionaries. Ashoka established a model of governance based on dharma principles like non-violence, tolerance, and compassion that had a lasting influence on Indian society.
