The caste system in India represents one of the most enduring and complex systems of social stratification. Often misunderstood as a monolithic institution extending unchanged from ancient times, the caste system underwent significant transformations, particularly during the colonial period. This study examines the historical evolution from the Vedic varna system to the institutionalized rigid caste hierarchy established during British colonial rule. Understanding this transformation is crucial for comprehending contemporary India's social structure and the persistent inequalities that characterize Indian society.¹

The distinction between the Vedic varna and the later jati (caste) systems is fundamental to this analysis. While the varna system was originally conceived as a flexible classification based on occupation and social function, it gradually transformed into a hereditary and birth-determined system. The British colonial administration further crystallized caste categories and institutionalized them within a rigid bureaucratic framework through mechanisms such as the census and legal codification.² This study traces this evolution in four major phases: the Vedic varna system, its gradual rigidification in medieval India, the early colonial encounter with caste, and finally, the formal institutionalization of caste as a colonial administrative category.

2. The Ancient Varna System: Origins and Flexibility

2.1 The Four-Fold Classification System

The earliest references to social classification in India appear in the Rigveda, particularly in the Purusha Sukta of the tenth mandala, which describes the Vedic creation myth and the origins of the four varnas.³ According to this mythological account, the four varnas—Brahmins (priests and scholars), Kshatriyas (warriors and rulers), Vaishyas (traders and merchants), and Shudras (laborers and service providers)—emerged from different parts of the cosmic person. However, this mythological origin story must be understood in its historical context.⁴

During the Rigvedic period (approximately 1500-1000 BCE), the varna system represented a broad theoretical classification based primarily on occupation and aptitude rather than birth status.⁵ Unlike the later hereditary caste system, the individual varnas in this period were not permanently fixed. A person's varna was determined more by their occupational function and social contribution than by hereditary succession. This flexibility is evidenced by the fact that the system allows for changes in social position based on achievement and personal merit.⁶

2.2 Social Mobility and Occupational Flexibility

The Early Vedic period was characterized by substantial social fluidity. Women, particularly those from higher varnas, retained considerable freedom. The Upanayana ceremony (sacred investiture), which granted access to Vedic education, was available to women of the first three varnas, not just males.⁷ Women could participate in intellectual discourse, marry by choice, and engage in public affairs. This stands in stark contrast to the restrictions imposed on women in later periods through the rigidification of the caste and varna hierarchies.

The Later Vedic period (approximately 1000-600 BCE) witnessed gradual but significant changes in this flexible system. The varna hierarchy became increasingly immobile, and individual varna status began to be determined by birth rather than occupation or merit.⁸ The transition from a fluid occupational categorization to a hereditary, birth-based system represents the first major transformation in Indian social organization, which would eventually culminate in the rigid caste system of later centuries.

2.3 The Emergence of Jati and the Transformation of Varna

The concept of jati (literally meaning "birth") emerged gradually from within the varna framework, representing a more complex and localized form of social organization.⁹ Jatis were endogamous groups—defined by strict marriage restrictions within the group—and served as mechanisms for organizing labor at the village and regional levels. The distinction between varna and jati is crucial: varna was a pan-Indian theoretical classification, whereas jati represented specific regional and occupational communities with their own rules, rituals, and social boundaries.

By the time of the compilation of the Manusmriti (conventionally dated between 200 BCE and 200 CE), the varna system had become significantly more rigid and had begun to merge with the proliferating jati system, providing religious, philosophical, and legal sanctions for an increasingly hierarchical social order. It established rules governing ritual purity and impurity, prescribed occupations for each varna, and justified the social subordination of lower castes through the concepts of ritual pollution and accumulated karmic debt. Thus, the sacred texts transformed what may have begun as a functional classification system into a religious mandate for social inequality.

MEDIEVAL DEVELOPMENTS AND INCREASED RIGIDITY

3.1 The Codification of Hierarchy

During the medieval period, particularly after the first century CE, the rigidity of the caste system intensified. Texts such as the Manusmriti codified behavioral expectations for each varna, prescribed occupations, regulated marriage practices, and established complex systems of ritual purity and pollution.¹¹ Outside the four varnas sat the Ati-Sudras (sometimes called the fifth varna or Chandalas), later to be known as "untouchables." These groups were relegated to occupations considered ritually polluting, such as scavenging, tanning hides, and cremation, and were subjected to systematic social exclusion and discrimination.

The medieval period witnessed the elaboration of sub-castes (jātīs) within and, at times, across varṇa boundaries. Urban centers like Ujjayini developed complex stratifications based on occupation, ethnicity, and ritual status, creating what might be termed a proto-caste system with an increasing emphasis on hereditary determination of status and occupation.¹²

3.2 The Role of Religious Institutions

Religious institutions played a crucial role in maintaining and elaborating on the caste system during the medieval period. Temples, monasteries, and religious establishments often had their own hierarchies, reflecting and reinforcing broader caste divisions. Temple patronage became a mechanism through which caste status and claims of ritual purity were negotiated and contested. The development of devotional movements (Bhakti), while sometimes critical of the caste hierarchy, ultimately failed to dismantle the system and were themselves often absorbed into caste-specific religious organizations.¹³

THE EARLY COLONIAL ENCOUNTER WITH CASTE (1757-1850)

4.1 British Perceptions and Initial Policies

The British East India Company and, later, the British Raj encountered the caste system in India as an already complex and deeply embedded social institution. However, British administrators, influenced by eighteenth-century Orientalism and racialized thought, interpreted caste through the lens of European racial categories and religious hierarchies.¹⁴ Early British scholars such as William Jones and Henry Thomas Colebrooke engaged in detailed studies of Sanskrit texts, particularly the Manusmriti, and presented these ancient texts as authoritative descriptions of how Indian society actually functioned. This conflation of textual prescriptions with social realities has profound consequences.

British administrative policies in the early colonial period did not initially attempt to reform or dismantle the caste system in India. Instead, the Company often sought to accommodate caste-based divisions, recognizing caste leaders as intermediaries through whom colonial authority was exercised. However, the very act of British rule and the introduction of new administrative structures began to transform the functioning of caste.¹⁵

4.2 Early Legal Codification

During the late eighteenth and early nineteenth centuries, British administrators began a process of legal codification that eventually institutionalized caste. The creation of written codes, the appointment of Brahmanical scholars as advisors on "Hindu Law," and the subordination of customary law to written legal codes all contributed to a process of "Brahminization" in which upper-caste interpretations of law and society became enshrined in colonial legal frameworks.¹⁶ This process inadvertently reinforced the authority of the upper castes and made caste distinctions more rigid and formal than they may have been previously.

5. THE CENSUS AND THE INSTITUTIONALIZATION OF CASTE (1871-1930)

5.1 The Census of India: Creating Fixed Categories

The most transformative moment in the colonial institutionalization of caste came with the decennial Census of India, beginning with the 1871 Census. For the first time in history, an attempt was made to enumerate and categorize the entire population according to caste.¹⁷ The census introduced what David Washbrook and other scholars have termed "caste as a fixed category"—transforming what had been a more fluid and context-dependent set of social relationships into seemingly objective, enumerated, and rigid social categories.

The Census commissioners, particularly Herbert Risley, approached caste classification with the presumption that caste was a timeless and unchanging feature of Indian society that could be objectively recorded and categorized. Census enumerators had to make countless decisions about how to classify individuals when caste identities were ambiguous, competing or changing. These administrative decisions, made by colonial officials often relying on Brahmanical sources and assumptions, fixed and formalized caste categories in unprecedented ways.

5.2 Caste Associations and Colonial Enumeration

Paradoxically, the census itself sparked organized collective action among the caste groups. Lower castes, in particular, began to form associations specifically designed to contest their classification in the census and demand higher status classifications in subsequent enumerations.¹⁹ The Shilpakar Mahasabha in Uttarakhand and similar organizations in other regions emerged to pressure colonial administrators to record caste status in ways that group members considered honorable. These caste associations thus became both responses to colonial categorization and agents reinforcing caste consciousness as a fixed, contestable category.²⁰

6. Colonial Legal Reforms and Caste Rigidification

6.1 Caste and Colonial Law

Despite its ostensible modernity and universalist pretensions, the British colonial legal system reinforced and formalized caste divisions in multiple ways. The Scheduled Castes Order of 1936 officially identified those castes deemed to be suffering from "untouchability."²¹ This legal enumeration gave administrative force to the concept of untouchability and created legal categories that were inherited by post-colonial India.

British administrators, influenced by "divide and rule" political strategies and by assumptions rooted in racial and caste hierarchies, deliberately divided Indian society along lines of caste, religion, and ethnicity.²² Land revenue systems, such as the Ryotwari system in South India, often reinforced caste-based land ownership patterns, transforming what had been relatively flexible local arrangements into rigid, documented, and legally enforced property rights that reflected and reinforced caste hierarchies.²³

6.2 The Question of Caste and Conversion

Colonial policies regarding religious conversion illuminate the paradox of colonial engagement with caste. Christian missionaries and some colonial officials viewed the caste system as an obstacle to Christian conversion and sought to encourage the conversion of lower castes to escape caste discrimination.²⁴ However, as nationalist discourse developed, caste became increasingly integral to Hindu or Indian national identity. The tension between viewing caste as a religious or civilizational problem to be solved and viewing it as a defining feature of Indian civilization was never fully resolved in the colonial discourse.

7. Resistance, Reform, and the Solidification of Caste (1850-1947)

7.1 Non-Brahmin and Anti-Caste Movements

Even as British policies hardened caste boundaries, significant social reforms and anti-caste movements emerged within Indian society. The nineteenth century witnessed vibrant caste discourse in regions such as Maharashtra, where nationalist intellectuals, low-caste movements, and religious reformers engaged in intense debates about caste, emancipation, and social reform.²⁵ Reformers like Jyotirao Phule and Savitribai Phule challenged Brahmanical orthodoxy and worked to uplift the status of untouchables through education and social organization. The Bhakti movement's critique of the caste hierarchy, while ultimately not dismantling the system, provided an alternative moral vision of human equality based on devotion rather than birth status.

However, these movements confronted a fundamental structural problem: as caste categories became increasingly fixed through colonial enumeration and legal frameworks, challenging the entire system became increasingly difficult. Paradoxically, the struggles against caste discrimination often required accepting and working within the categories created by the colonial census.²⁶

7.2 The Constitutional Moment and Ambedkar's Vision

Dr. B. R. Ambedkar emerged in the mid-twentieth century as the most significant intellectual voice calling for the annihilation of the caste system. His 1936 speech, Annihilation of Caste,” articulated a radical vision of social transformation that would require not merely reform within the caste system but its complete destruction.²⁷ Ambedkar's leadership in the Constituent Assembly debates (1946-1949) ensured that the Constitution of Independent India enshrined the abolition of untouchability and discrimination on the grounds of caste.

8. The Legacy of Institutionalization: Post-Colonial Continuities

8.1 Caste in Independent India

Despite the constitutional prohibition of caste discrimination, the institutionalization that occurred during the colonial period created structural legacies that persisted in independent India.²⁸ The Census of India continued to enumerate caste categories (though this practice has been discontinued for non-Scheduled Caste and non-Scheduled Tribe populations in recent decades). The state’s administrative apparatus, inherited from colonial structures, continued to recognize and work through caste categories in implementing policies related to reservations and social welfare.

The reservation (affirmative action) system established for Scheduled Castes (ex-untouchables) and Scheduled Tribes represents an attempt to address historical injustices through legal and constitutional means. However, this also institutionalized caste categories as official state categories, creating a paradox wherein the attempt to remedy caste discrimination required continued official recognition of caste identity.²⁹

8.2 Caste as Persistent Institution

Contemporary scholarship increasingly recognizes that the rigidification of caste during the colonial period, while significant, did not represent the wholesale invention of the caste system.³⁰ Rather, colonial processes transformed preexisting caste practices in significant ways: they made categories fixed and enumerated, removed the possibility of contextual flexibility that had sometimes existed before, and gave caste official state recognition in unprecedented ways. The result was an institutionalized caste system that was more rigid than anything that had existed previously.

The evolution from the ancient varna system to the rigid, institutionalized caste system of contemporary India represents a centuries-long historical process rather than an unchanging tradition or colonial invention. The ancient Vedic varna system, while establishing hierarchical divisions, retained significant occupational and social fluidity within its structure. Medieval developments, particularly the elaboration of jati categories and religious codification, have increased rigidity. Colonial policies and institutions—most significantly the census, legal codification, and administrative enumeration—transformed these preexisting social categories into fixed, official, and systematized divisions.

This institutionalization created a paradox: the very categories invented to understand and govern Indian society became integral to how Indians came to understand themselves and their place in society. Post-colonial India inherited this institutionalized caste system and, despite constitutional commitments to abolish caste discrimination, has continued to work with caste categories as administrative and legal realities.³¹

Understanding this history is essential for contemporary efforts to address such caste discrimination. This reveals that caste is neither merely an ancient religious system nor a purely colonial invention, but rather a complex historical formation shaped by pre-colonial developments, colonial transformation, and post-colonial institutional persistence. Addressing contemporary caste-based inequality requires confronting not only the ideological justifications of caste but also the concrete institutional structures through which caste categories continue to organize access to resources, opportunities, and dignity in Indian society.
