The Indian caste system is a hereditary, endogamous system of social stratification built from two interlocking concepts: varna, four idealized ritual-status categories described in ancient texts, and jati, thousands of localized, occupationally and regionally rooted endogamous groups that structure actual social life. Its textual roots reach back to the Rigveda (c. 1500-1000 BCE), which originally distinguished only two broad categories; the fourfold varna scheme developed over the following centuries, and rigid enforced endogamy consolidated particularly during the Gupta period (319-550 CE). A major scholarly divide separates an 'ideological' school, which reads the ancient normative texts as evidence the system was stable for millennia, from a 'socioeconomic' school associated with scholars like Nicholas Dirks, who treat caste as an ever-evolving social reality shaped by shifting economic and political history, arguing the rigid, exhaustively enumerated caste system familiar today is substantially a colonial-era construction.

Disputed
Emergence PeriodVedic period roots (c. 1500-1000 BCE), rigid endogamy by the Gupta period (319-550 CE); modern rigid form contested as possibly a colonial-era construction 1 Sourced to the subject's own accountTextual roots lie in the Vedic period (c. 1500-1000 BCE) with the four-varna structure developed by the Later Vedic period (1000-600 BCE) and rigid endogamy consolidating by the Gupta period (319-550 CE); but whether the rigid, exhaustively codified caste system experienced today reflects continuous ancient tradition or is substantially a colonial-era hardening of a previously fluid social order (Nicholas Dirks's colonial-construction thesis) is an active, unresolved historiographical dispute, not settled consensus.

Both are property-adjacent, hereditary or quasi-hereditary systems of stratification, though caste is not premised on legal ownership of the person the way slavery is.
The caste system is a hereditary, endogamous form of social stratification; a specific historical instance of the general institution.

Does the rigid, exhaustively enumerated Indian caste system reflect continuous ancient tradition, or is its modern form substantially a colonial-era construction hardened by British administration?
An "ideological" school reads ancient normative texts (the Manusmriti, the Rigveda) as evidence the system was stable for millennia, while a "socioeconomic" school associated with scholars like Nicholas Dirks and Susan Bayly treats caste as an ever-evolving social reality substantially hardened into its rigid modern form by 19th-20th century British colonial census classification, the Criminal Tribes Act, and land-alienation laws.
What would resolve this A systematic historical-demographic comparison of caste rigidity and enumeration practices before and after the onset of British colonial administration, tracing whether endogamy and jati boundaries were as fixed and countable in pre-colonial sources as colonial census records later made them appear.

Frequently Asked Questions
Is the caste system unique to India?
The specific varna and jati system is a distinctively Indian institution, but sociologists treat caste as one named example of a broader family of closed, hereditary, endogamous stratification systems found in other societies too.
The Indian caste system, built from the four textual varna categories and thousands of localized jati groups, is a specific historical institution with its own textual and regional roots. Sociologists nonetheless use caste as a general comparative category for any hereditary, endogamous stratification system that closes off marriage and, often, occupation across generations, and have applied it, with real debate over how well the term travels, to hierarchies in other societies. How much of the modern, rigidly enumerated Indian system reflects ancient continuity versus colonial era administrative hardening is itself a live, unresolved scholarly question, carried on this atlas as its own open question.
