The Mauryan emperor Ashoka had royal proclamations carved on polished sandstone pillars and on rocks across his empire, declaring a policy of dhamma: moral governance, religious tolerance, public welfare, and the provision of wells, rest-houses, shade-trees and medical care along roads. Written in local languages and scripts, the edicts addressed subjects directly and announced state-sponsored infrastructure and ethical administration. The pillars, crowned with finely carved animal capitals, marked routes, sacred sites and the reach of imperial authority. They constitute the earliest extensive body of state public-policy texts in South Asia.
Ashoka's programme is an early model of governance that joined moral legitimacy with public works and welfare infrastructure across a vast territory. The pillar-and-edict network materialised state authority in the landscape, a template echoed by later rulers.
