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.
Brahmana (now more commonly spelled Brahmin): Consist of those engaged in scriptural education and teaching, essential for the continuation of knowledge.
Kshatriya: Take on all forms of public service, including administration, maintenance of law and order, and defense.
