The caste system in India is a system of social stratification,[2] which is now also used as a basis for affirmative action.[3][4] Historically, it separated communities into thousands of endogamous hereditary groups called Jātis,[5] which is synonymous with caste in contemporary usage. The Jātis were grouped by the Brahminical texts into four categories or varnas: Brahmins, Kshatriyas, Vaishyas and Shudras.
