The Edicts of Ashoka are a collection of 33 inscriptions on the Pillars of Ashoka, as well as boulders and cave walls, made by the Emperor Ashoka of the Mauryan dynasty during his reign from 272 to 231 BC. These inscriptions are dispersed throughout the areas of modern-day Pakistan and northern India, and represent the first tangible evidence of Buddhism. The edicts describe in detail the first wide expansion of Buddhism through the sponsorship of one of the most powerful kings of Indian history. According to the edicts, the extent of Buddhist proselytism during this period reached as far as the Mediterranean, and many Buddhist monuments were created.
