Caste is popularly understood as a uniquely Indian and Hindu system of social organization. In the sociological writings, it is often viewed as a “closed system” of social stratification in which social groups, often divided on the basis of their occupations, strictly follow a code of behavior prescribed by tradition regarding marriage and kinship alliances. Caste groups are unequal, ranked on a scale of hierarchy on the basis of their ritual status, from pure to impure. The hierarchy is sanctioned by the Hindu religious belief. Their “status” or position in the system determines with whom they can and cannot interact.
