Chakravartin Ashoka Samrat
Ashoka the Great (r. 268-232 BCE) was the third king of the Mauryan Empire (322-185 BCE) best known for his renunciation of war, development of the concept of dhamma (pious social conduct), and promotion of Buddhism as well as his effective reign of a nearly pan-Indian political entity.
At its height, under Ashoka, the Mauryan Empire stretched from modern-day Iran through almost the entirety of the Indian subcontinent. Ashoka was able to rule this vast empire initially through the precepts of the political treatise known as the Arthashastra, attributed to the Prime Minister Chanakya (also known as Kautilya and Vishnugupta, l. c. 350-275 BCE) who served under Ashoka's grandfather Chandragupta (r. c. 321-c.297 BCE) who founded the empire.
Ashoka means “without sorrow” which was most likely his given name. He is referred to in his edicts, carved in stone, as Devanampiya Piyadassi which, according to scholar John Keay (and agreed upon by scholarly consensus) means “Beloved of the Gods” and “gracious of mien” . He is said to have been particularly ruthless early in his reign until he launched a campaign against the Kingdom of Kalinga in c. 260 BCE which resulted in such carnage, destruction, and death that Ashoka renounced war and, in time, converted to Buddhism, devoting himself to peace as exemplified in his concept of dhamma. Most of what is known of him, outside of his edicts, comes from Buddhist texts which treat him as a model of conversion and virtuous behavior.
The empire he and his family built did not last even 50 years after his death. Although he was the greatest of the kings of one of the largest and most powerful empires in antiquity, his name was lost to history until he was identified by the British scholar and orientalist James Prinsep (l. 1799-1840 CE) in 1837 CE. Since then, Ashoka has come to be recognized as one of the most fascinating ancient monarchs for his decision to renounce war, his insistence on religious tolerance, and his peaceful efforts in establishing Buddhism as a major world religion.
