Ashoka appointed dhamma mahamatta, or "inspectors of the dhamma," to solve the social problems in his region. These officials were responsible for spreading the teachings of the Buddha and promoting peace and harmony among the people. They also served as diplomats and envoys to other countries.

Ashoka's dhamma mahamatta were a key part of his policy of dhammavijaya, or "conquest by dhamma." They were responsible for spreading the message of the Buddha throughout the Mauryan Empire and beyond.
