According to Dumont (1980), the caste system played a main role to exist the hierarchy in a society. He claims caste divides the whole Indian society into a larger number of hereditary groups distinguished from one another and connected together by three characteristics:
1. Separation on the basis of rules of the caste in matters of marriage and contact whether direct or indirect.
2. Interdependent of work or division of labor each group having in theory or by tradition, a profession from which their members can depart only within certain limits.
3. Hierarchy which ranks the groups as relatively superior or inferior to one another.
