The caste system in India is a system of social stratification which has pre-modern origins, was transformed by the British Raj, and is today the basis of reservation in India. It consists of two different concepts, varna and jāti, which may be regarded as different levels of analysis of this system. Varna may be translated as “class,” and refers to the four social classes which existed in the Vedic society, namely Brahmins, Kshatriyas, Vaishyas and Shudras.
Genocide is the deliberate and systematic destruction, in whole or in part, of an ethnic, racial, religious or national group. The term was coined in 1944 by Raphael Lemkin.
