"Asoka (264 to 227 B.C.), one of the great monarchs of history, whose dominions extended from Afghanistan to Madras... is the only military monarch on record who abandoned warfare after victory. He had invaded Kalinga (255 B.C.), a country along the east coast of Madras, perhaps with some intention of completing the conquest of the tip of the Indian peninsula. The expedition was successful, but he was disgusted by what be saw of the cruelties and horrors of war. He declared, in certain inscriptions that still exist, that he would no longer seek conquest by war, but by religion, and the rest of his life was devoted to the spreading of Buddhism throughout the world. He seems to have ruled his vast empire in peace and with great ability. He was no mere religious fanatic."
