Varna and caste
Purusha hymn c. 1000 BC; debated ever since· Belief or practice· Hindu, Buddhist, Jain & Sikh
Debated by scholarsHistorians and scholars disagree.
The four social classes (varna) described in Hindu scripture, and the thousands of birth-based groups (jati) that formed India's caste system.
See it on the World Religions map →What it is
A late Rigveda hymn, the Purusha Sukta, pictures society arising from a cosmic man: Brahmins (priests) from his mouth, Kshatriyas (warriors) from his arms, Vaishyas (merchants, farmers) from his thighs, Shudras (laborers) from his feet. Law books like the Manusmriti set duties for each. In practice people belonged to thousands of jatis, groups that married within themselves and were often tied to an occupation. Those deemed 'untouchable', now often called Dalits, faced severe exclusion.
Why it matters
Caste has shaped Indian society for over 2,000 years and provoked challenges from Buddhism, Sikhism and modern reformers. India outlawed untouchability in 1950 and reserves jobs and university places for lower castes.
Sources and history
Ancient texts (Rigveda, Manusmriti); Greek and Chinese travelers' accounts; British censuses from 1871; and genetic studies suggesting strict in-group marriage set in roughly 2,000 years ago.
Questions and debates
How rigid caste was before British rule, which classified and arguably hardened it, and how far it is religious rather than social, are debated.

Connections (5)
▸Rigveda first names the four classes of Varna and casteHistorical record
The connection
The Purusha hymn (Rigveda 10.90) describes the gods sacrificing a cosmic man: priests (Brahmins) came from his mouth, warriors (Kshatriyas) from his arms, commoners (Vaishyas) from his thighs and servants (Shudras) from his feet. Later law books cited it to ground a ranked social order.
When and where
Book 10 of the Rigveda, among its latest hymns, about 1000 BC, in northwest India.
Historical evidence
The hymn survives in every Rigveda recitation tradition; its late language and placement lead scholars to see it as a later addition.
Questions and debates
How far the four varnas described real society rather than a priestly ideal, and how they relate to jati, the thousands of birth groups of caste in practice.
▸Varna and caste was framed through Dharma: duty and cosmic orderDebated by scholars
The connection
Hindu law books tied each person's dharma, or duty, to their varna and stage of life: priests teach and sacrifice, warriors protect, merchants trade, laborers serve. The Bhagavad Gita says it is better to do one's own duty imperfectly than another's well. This gave birth-based roles religious weight.
When and where
The Dharma Sutras and the Manusmriti, c. 500 BC–AD 200; the Bhagavad Gita, c. 200 BC–AD 200.
How do we know?
The texts state it directly, especially the Manusmriti; how fully everyday society followed them is far less certain.
Questions and debates
Whether dharma texts described society or prescribed a priestly ideal, and how far British rule hardened caste's religious basis, are debated.
▸Hindu reform movements (Brahmo Samaj, Arya Samaj) challenged Varna and casteHistorical record
The connection
Ram Mohan Roy's Brahmo Samaj (1828) opened its worship to all and, under later leaders, dropped caste rules altogether. Dayananda Saraswati's Arya Samaj (1875) argued varna should rest on merit, not birth, called untouchability a later corruption of Vedic religion, and opened Vedic learning to all castes and to women.
When and where
Calcutta (Kolkata), 1828, and Bombay (Mumbai), 1875, under British rule; the Arya Samaj then spread across Punjab and northern India.
Historical evidence
Their founding writings, such as Dayananda's Satyarth Prakash (1875), and records of Arya Samaj ceremonies admitting lower-caste members.
Questions and debates
Historians debate how much these largely upper-caste movements changed caste practice, versus mainly reshaping elite opinion.
▸Mahatma Gandhi campaigned against untouchability in Varna and casteHistorical record
The connection
Gandhi called untouchability Hinduism's great sin, renamed the 'untouchables' Harijans ('people of God'), toured India against it and fasted for their cause. Yet for years he defended varna as a division of duties, putting him at odds with B. R. Ambedkar, who wanted caste abolished.
When and where
India, 1920s–1940s: the 1932 Poona Pact with Ambedkar, the Harijan Sevak Sangh founded that year, and his 1933–34 anti-untouchability tour.
Historical evidence
Gandhi's own writings in Young India and Harijan; records of his fasts and tours; Ambedkar's critique in Annihilation of Caste (1936).
Questions and debates
Gandhi's views shifted over time; historians and Dalit activists still debate whether he advanced or slowed caste abolition. Many Dalits now find 'Harijan' patronizing.
▸Ambedkar leads Dalits to Buddhism was a protest against Varna and casteHistorical record
The connection
Ambedkar argued caste was rooted in Hindu scripture itself; in 1927 he publicly burned the Manusmriti, an ancient law code, and his 1936 'Annihilation of Caste' urged rejecting its authority. After decades of campaigns for temple and water access, he concluded reform from within had failed and chose Buddhism, which he saw as teaching equality.
When and where
Mahad, 1927; Yeola, 1935; Nagpur, October 14, 1956; Ambedkar with hundreds of thousands of mostly Mahar Dalits.
Historical evidence
Ambedkar's speeches and writings, the text of the 22 vows rejecting Hindu gods and caste, and contemporary press coverage.
Questions and debates
Gandhi wanted to reform Hinduism instead; whether conversion has reduced discrimination is debated, since caste bias persists across religions.
