India’s caste system is a social structure that divides different groups into ranked categories. Members of “higher” castes have a greater social status than individuals of a “lower” caste. Indian law prohibits discrimination by caste, although caste identities remain of great significance at the local level, especially in relation to marriage. A survey in 2005 found that only 11 per cent of women had married a man of different caste.
The system appears to have had ancient roots. Sanskrit texts from the second millennium BC refer to a practice of dividing individuals into social groups called “varnas”—the term’s precise meaning is unclear, but is seems not only to suggest classification, but also colour. The Varnas, which are associated with early Hinduism, are the first recorded manifestation of India’s caste system. Four principal classes emerged, in descending order of prestige: the Brahmins, the Kshatriyas, the Vaishyas and the Shudras. Myth holds that these groups were created from the mouth, arms, thighs and feet of an ancient character called Purusha.
