Traditionally, they have been record keepers and scribes. They were appointed by Shivaji as custodians of his forts and held high offices in Peshwa and Mughal times but later shifted their allegiance to the Nizam, the Gaekwads and Holkars. With the advent of British rule they became clerks and 'vakils' (lawyers) and took up service in the army.
