Ashoka, last major emperor in the Mauryan dynasty of India. His vigorous patronage of Buddhism during his reign (c. 265–238 bce; also given as c. 273–232 bce) furthered the expansion of that religion throughout India. In order to gain wide publicity for his teachings and his work, Ashoka made them known by means of oral announcements and by engravings on rocks and pillars at suitable sites. These inscriptions—the rock edicts and pillar edicts (e.g., the lion capital of the pillar found at Sarnath, which has become India’s national emblem), mostly dated in various years of his reign—contain statements regarding his thoughts and actions and provide information on his life and acts. His utterances rang of frankness and sincerity.
