Caste and Social Structure in Ancient and Medieval India
Caste — the varna-jati system — is India's most persistent social institution, shaping economy, politics and culture over three millennia. Understanding its Vedic origins, medieval consolidation, internal dynamics and historical debates is essential for both GS1 History and GS1 Society questions.
1. Varna: The Textual Framework
The varna system (four-fold division) appears first in the Rigveda's Purusha Sukta (X.90): all beings were created from the primordial sacrifice of Purusha; from his mouth emerged Brahmins, from his arms Kshatriyas, from his thighs Vaishyas, from his feet Shudras.
The four varnas:
| Varna | Traditional function | Vedic colour (symbolic) |
|---|---|---|
| Brahmin | Priestly, scholarly | White |
| Kshatriya | Warrior, ruling | Red |
| Vaishya | Merchant, agriculturalist | Yellow |
| Shudra | Service, labour | Black |
Outside this system were the avarna — those "below" the varna classification, later called untouchables (asprishya), chandalas, Panchamas, and in colonial/modern period Scheduled Castes or Dalits.
Crucial distinction: Varna is a textual/theoretical four-fold scheme; jati (caste by birth) is the actual social group one is born into — there are thousands of jatis across India, each with its own endogamy rules, occupational norms, ritual status and regional variation. Varna is the theoretical framework; jati is the lived reality.
2. Origin Theories
Occupational theory: Varna was originally based on occupation, not birth; it became hereditary over time. The Bhagavad Gita (4.13) says varnas are created by guna (quality) and karma (action), implying merit-based division.
Birth/ritual purity theory: The dominant brahmanical view is that varna is determined by birth into a particular family, and birth itself reflects the karma of previous lives. This made the hierarchy appear divinely sanctioned.
Social-economic theory (Kosambi, Sharma): Varna arose from the integration of tribal peoples into the Aryan social order — conquered or absorbed tribes were given Shudra or lower status; the Brahmin-Kshatriya alliance secured brahminic ritual authority and Kshatriya political power.
3. Evolution Through Time
Vedic Period (c. 1500–600 BCE)
- Early Vedic society: varna boundaries were more fluid.
- Later Vedic period (1000–600 BCE): Varna becomes more rigid; Brahminic texts elaborate complex ritual rules; mixed marriages (pratiloma — higher-status woman with lower-status man — are stigmatised).
Mahajanapada / Buddhist Period (600–300 BCE)
- Buddhism and Jainism challenged varna hierarchy — accepted converts across castes.
- The commercial revolution created wealthy Vaishya merchants; some Kshatriya republics were powerful; the Brahmin priestly monopoly was partially contested.
Mauryan and Post-Mauryan (300 BCE – 300 CE)
- Ashoka's Dhamma implicitly challenged varna discrimination.
- Post-Mauryan period: Multiple foreign groups (Indo-Greeks, Shakas, Kushanas, Hunas) integrated into Indian society — often given Kshatriya status through brahminic rituals.
- Dharmashastras (Manusmriti, c. 2nd century CE): Most systematic brahminic codification of varna rules, gender roles and untouchability. Manusmriti has been a primary target of Dalit and feminist criticism.
Gupta Period (320–550 CE)
- Often called the "Hindu revival" — brahminic norms were reasserted after Buddhist challenge.
- Agrahara grants: Villages donated to Brahmins; created a landholding Brahmin class.
- Untouchability became more elaborate and enforced — the Chinese traveller Fa-Hien noted that Chandalas were required to make a noise when approaching towns so "clean" castes could avoid them.
Medieval Period (600–1700 CE)
- Jati proliferation: The number of recognised jatis multiplied enormously as communities specialised in new occupations (weavers, oilpressers, leatherworkers).
- Dominant castes: In each region, one or two agricultural/warrior castes came to dominate — Rajputs in Rajasthan, Vellalas in Tamil Nadu, Kamma and Reddy in Andhra, Jats in Punjab. These dominant castes controlled land and local power.
- Bhakti challenge: Saints like Kabir (weaver caste), Ravidas (cobbler caste), Chokhamela (Mahar caste) challenged caste hierarchy explicitly. But Bhakti movements generally did not produce lasting structural change in the caste system.
- Islam and caste: Islam rejected caste doctrinally; in practice, converted communities often retained caste identities. Ashraf (high-status Muslims: Sayyids, Sheikhs, Mughals, Pathans) vs Ajlaf (lower-status Muslim converts) distinctions replicated caste hierarchy within Islam.
4. Untouchability
Untouchables were assigned the most "polluting" occupations — handling corpses, leather, human waste, sweeping. They lived outside village boundaries; were denied access to temples, wells and public spaces.
Historical debates:
- Ambedkar's thesis (The Untouchables, 1948): Untouchables were originally Buddhists who resisted conversion to brahmanical Hinduism after the Gupta period — hence treated with extreme contempt.
- Alternative view: Untouchability arose from ritual purity/pollution concepts that pre-dated Buddhism.
5. Colonial Period and Caste
- The caste census (1871 onwards) reified caste — turned fluid local hierarchies into fixed administrative categories.
- Separate caste-based representation in legislatures (Communal Award 1932) — applied the logic of communal representation to caste.
- Reform movements: Jyotiba Phule (non-Brahmin movement, Maharashtra), Periyar (Self-Respect Movement, Tamil Nadu), Ambedkar (Dalit movement) challenged caste from within Indian society.
6. UPSC Relevance
Prelims: Purusha Sukta = Rigveda X.90; Manusmriti = Dharmashastra of c. 2nd century CE; Fa-Hien's account of Chandalas; Bhakti saints from low castes — Kabir (weaver), Ravidas (cobbler).
Mains GS1: "Caste was more fluid in ancient India than brahminic texts suggest — it only became rigid under colonial enumeration." Discuss. | Trace the evolution of untouchability from Vedic times to the colonial period. | How did the Bhakti movement challenge — and fail to overthrow — the caste system?
GS1 Society: Caste and its contemporary manifestations; caste discrimination as a continuing social challenge.
Frequently Asked Questions
What is the difference between varna and jati?
Varna is the theoretical fourfold order (Brahmana, Kshatriya, Vaishya, Shudra), while jati refers to the numerous birth-based occupational groups that operate in practice.
What is the Purusha Sukta?
It is a hymn of the Rigveda that describes the origin of the four varnas from the body of the cosmic being Purusha.
How did the caste system change in medieval India?
There was a proliferation of jatis, the rise of new dominant castes, and challenges to caste hierarchy from Bhakti and Sufi movements.
How did the Bhakti movement challenge caste?
Many Bhakti saints preached that devotion was open to all regardless of birth, criticising ritual hierarchy and untouchability.
