The practice of untouchability is outlawed by the constitution of India. It is the oldest system of degradation of human beings. And, it is still practised in rural, as well as in urban India. It is also evident that the degree of assertion has risen among the Scheduled Castes all over India. They are resisting the graded hierarchy and inequality by all means possible. The caste system in India is the paradigmatic ethnographic example of caste. It has origins in ancient India, and was transformed by various ruling elites in medieval, early-modern, and modern India, especially the Mughal Empire and the British Raj.It is today the basis of affirmative action programmes in India.The caste system consists of two different concepts, varna and jati, which may be regarded as different levels of analysis of this system.
