Some of the most momentous developments in Indian epigraphy took place in the 1830s. This was when James Prinsep, an officer in the mint of the East India Company, deciphered Brahmi and Kharosthi, two scripts used in the earliest inscriptions and coins. He found that most of these mentioned a king referred to as Piyadassi – meaning “pleasant to behold”; there were a few inscriptions which also referred to the king as Asoka, one of the most famous rulers known from Buddhist texts.

Asoka was the first ruler who inscribed his messages to his subjects and officials on stone surfaces – natural rocks as well as polished pillars. He used the inscriptions to proclaim what he understood to be dhamma. This included respect towards elders, generosity towards Brahmanas and those who renounced worldly life, treating slaves and servants kindly, and respect for religions and traditions other than one’s own. Asoka also tried to hold his empire together by propagating dhamma, the principles of which, as we have seen, were simple and virtually universally applicable. This, according to him, would ensure the well-being of people in this world and the next. Special officers, known as the dhamma mahamatta, were appointed to spread the message of dhamma.
