The caste system in India was used to give clerical jobs only to upper caste members.
 The four classes were the Brahmins (priestly people), the Kshatriyas (rulers, administrators and warriors; also called Rajanyas), the Vaishyas (artisans, merchants, tradesmen and farmers), and Shudras (labouring classes)
  There are 3,000 castes and 25,000 sub-castes in India, each related to a specific occupation
