Since the most ancient times brāhmaṇas—men of learning, austerity and character—have commanded the respect of the Hindu society. Kings used to vie with one another in granting land, cows and wealth to them for their personal use. Villages or lands (parts of villages) given to them for their maintenance have been known as ‘agrahāra.’ People living in such agrahāras were called ‘mahājanas.’ They were exempted by the kings from payment of taxes and also punishment for lapses in behaviour unless they were of a serious nature like treason, murder etc. The mahājanas themselves regulated the conduct of the inhabitants of the agrahāra.
Agrahāras were intended to be centres of learning and the mahājanas were expected to be models of conduct.
