Background and evolution

Two related but distinct ideas are often confused. Varna refers to the fourfold scheme of Brahmins, Kshatriyas, Vaishyas and Shudras described in some ancient texts, with groups considered "outside" the scheme later treated as untouchable. Jati refers to the thousands of real, local endogamous groups, often named after occupations or regions, which are the actual units of social life. Scholars debate how rigid caste was in early periods; many argue that colonial censuses and administrative classification from the late nineteenth century made caste categories more fixed and politically significant.

Reformers challenged caste for centuries: Bhakti saints such as Kabir and Ravidas, Jyotirao and Savitribai Phule in Maharashtra, Sree Narayana Guru in Kerala, E.V. Ramasamy (Periyar) in Tamil Nadu, and B.R. Ambedkar, who led the Mahad satyagraha (1927) and argued in "Annihilation of Caste" (1936) that caste was incompatible with democracy. The Constitution abolished untouchability, prohibited discrimination and created safeguards for Scheduled Castes and Scheduled Tribes.
