Caste in India is a birth-ascribed system of hierarchy, endogamy, hereditary occupation and purity-pollution rules that the Constitution forbids as a basis of discrimination but that still shapes marriage, politics and identity. UPSC tests it in GS Paper 1 as a living institution that keeps changing form, so aspirants need the key concepts, Ambedkar's analysis, the constitutional safeguards, the evidence and the debate over caste abroad.
Why in news: Dalit students and groups abroad have asked universities and legislatures to name caste as a protected ground in anti-discrimination law, reviving the question whether law alone can end caste. Seattle did so in 2023; California's statewide bill was vetoed.
Updated (October 2026): figures re-checked against NCRB and IHDS sources; concept comparison, Prelims traps and a 60-second revision added; unconfirmed news details removed.
Syllabus mapping
Prelims: Indian Polity (fundamental rights, Articles 15, 16, 17, 46, 330, 332, 341) and Current Events.
Mains GS Paper 1: ‘Salient features of Indian Society, Diversity of India’; ‘Social empowerment, communalism, regionalism & secularism’; ‘Effects of globalization on Indian society’.
What is caste and what are its key features?
Everything below rests on one definition. Caste (jati) is a hereditary group into which a person is born, ranked against other groups and bound by rules on marriage, food and work. It differs from varna, the four-fold scriptural order, because India has thousands of jatis.
Hierarchy: castes are ranked high to low; rank is fixed by birth, not merit or wealth.
Endogamy: marriage inside the group; the rule that holds the other features together.
Hereditary occupation: the traditional calling is passed down and the choice of work is restricted.
Purity-pollution: higher castes are ritually ‘pure’; contact, food and water are regulated, which is the root of untouchability.
Ghurye's list: G.S. Ghurye (*Caste and Race in India*, 1932) gave six features: segmental division, hierarchy, restrictions on food and social contact, civil and religious disabilities, no choice of occupation, and restrictions on marriage.
Key sociological concepts: X vs Y
The features above describe the structure; sociologists use a few look-alike ideas to describe how it moves, and UPSC likes to swap them.
Concept | Thinker | What it means | Do not confuse with |
|---|---|---|---|
Sanskritisation | M.N. Srinivas | A group adopts the customs, rituals and food habits of a higher caste to claim higher rank | Westernisation |
Westernisation | M.N. Srinivas | Change in dress, technology, institutions and ideas through contact with the West | Sanskritisation |
Dominant caste | M.N. Srinivas | A locally strong caste with land, numbers and political power; ritual rank is not decisive | The ritually highest caste |
Caste associations | Rudolphs; Kothari | Caste-based organisations that bargain for jobs, education and political voice | Traditional caste panchayats |
Remember it as: Sanskritisation moves the group up the ladder; it does not remove the ladder.
Worked example: a landowning or artisan caste adopts vegetarianism, sacred-thread rituals and a higher-caste origin story to claim better rank. The group moves; the hierarchy stays. Srinivas called this positional, not structural, change.
Caste, Class and Power (1965): André Béteille's study of a Tanjore village found that caste rank, wealth and power no longer coincide neatly.
Politicisation of caste: Rajni Kothari (*Caste in Indian Politics*, 1970) argued that democracy did not end caste; politics gave it a new arena.
What did Ambedkar say about caste?
Concepts describe how caste behaves; Ambedkar explained what holds it together and how to end it.
Endogamy is the key: in ‘Castes in India: Their Mechanism, Genesis and Development’ (1916, a Columbia seminar paper) he held that endogamy is the feature peculiar to caste.
A mental state, not a wall: in *Annihilation of Caste* (1936) he argued that caste rests on religious sanction, so the remedy lies in rejecting the authority of scriptures that uphold it.
Never delivered: the 1936 address, written for a Lahore reform group, was withdrawn after organisers objected to its contents; Ambedkar published it himself.
A world problem: in 1916 he warned that if Hindus migrated to other parts of the world, caste would become a ‘world problem’; the diaspora debate below revives that line.
How is caste changing?
Ambedkar's diagnosis was made before universal franchise and urban growth; both have since changed how caste works.
Urbanisation and occupation: anonymity in cities, new jobs and education loosen ritual rules on food, work and contact.
Politics: democracy turned caste into an electoral resource; caste associations and parties mobilise on identity, which is why UPSC speaks of caste ‘assuming new identities and associational forms’.
What has not changed: marriage. In IHDS-II (2011–12), 5.4 per cent of married women aged 15–49 reported an inter-caste marriage, no change from IHDS-I (2004–05) (NCAER).
Counting caste: the next big data point is the planned Census caste count; see Census 2027: the caste count and the open-column method.
What are the constitutional safeguards against caste discrimination?
Because social change has been slow, the Constitution works on caste from three sides: bars on discrimination, abolition of untouchability, and positive support for Scheduled Castes.
Article 15(1) and 15(2): no discrimination by the State on grounds including caste; 15(2) also covers access to shops, restaurants, hotels, places of public entertainment and the use of wells, tanks, ghats and roads, so it reaches private persons.
Article 16(2), 16(4), 16(4A): no discrimination in public employment; the State may reserve posts for backward classes not adequately represented; reservation in promotion is allowed for SCs and STs. Article 15(4) and 15(5) add special provisions, including in educational institutions.
Article 17: abolishes untouchability; see Untouchability in India: Article 17, the PCR Act and why law alone hasn't ended it.
Article 46 (DPSP): the State shall promote the educational and economic interests of weaker sections, especially SCs and STs, and protect them from social injustice.
Articles 330 and 332: seats for SCs and STs in the Lok Sabha and State Assemblies, extended to 2030 by the 104th Amendment (2019).
Articles 341 and 342, 338: the President specifies SCs and STs by notification; only Parliament by law can include or exclude a caste. Article 338 provides the National Commission for Scheduled Castes.
Statutes: the Protection of Civil Rights Act, 1955 punishes untouchability practices; the SC/ST (Prevention of Atrocities) Act, 1989 targets caste-based atrocities through special courts and relief for victims.
Issues and challenges
These safeguards are strong on paper; the data show where practice lags.
Violence persists: NCRB's *Crime in India 2023* recorded 57,789 cases of crimes against Scheduled Castes, a rise of about 0.4 per cent on 2022 (NCRB, 2023).
Mobility without equality: reservation helps access, not acceptance; marriage data above show the same gap.
At home: the 2016 death of Rohith Vemula, a Dalit research scholar, kept campus caste bias in national debate.
Caste abroad: should law name caste?
The same gap between law and practice has now appeared overseas, where the question is whether to name caste in law at all.
Seattle, 2023: the city council voted 6–1 to add caste to its anti-discrimination law, the first US city to do so.
California, 2023: SB 403, which would have made caste a protected category statewide, was vetoed; the Governor said existing categories such as ancestry already cover it.
The debate: supporters say naming caste gives victims a clear remedy; critics say it singles out one community. A balanced answer states both.
Milestones in the caste debate
The timeline joins theory, Constitution, statutes and the overseas debate in one line.
Way forward
Each gap above points to one remedy.
Enforce before adding laws: speedy trials, victim protection and relief under existing statutes.
Campus and workplace codes: explicit anti-caste policies in universities and firms.
Inter-caste marriage support: safe homes, incentives and protection against honour crimes.
Ambedkar's route: build fraternity through education, shared spaces and social reform, not only reservation.
The law has closed the formal doors of caste, but marriage and violence data show that social practice changes more slowly. Caste is carried by people, not place, so the remedy has to work on attitudes and institutions wherever Indians live.
Using caste in a Mains answer
The sections above fit one answer frame.
Introduction: define caste; say it is changing in form.
Body — concepts: features; Sanskritisation, associations, with the right thinker.
Body — change vs continuity: urbanisation and politics versus 5.4 per cent inter-caste marriage (IHDS-II).
Body — safeguards and gaps: Articles 15, 16, 17, 46; two statutes; NCRB 2023.
Way forward and conclusion: enforcement, social reform, Ambedkar, the diaspora as a fresh example.

Mentor’s note
Expect the ‘change or continuity’ question. Mains 2018 and 2020 both ask whether caste is changing or losing relevance; answer with both sides and an example, not a definition.
Attach the right thinker to the concept. Sanskritisation, Westernisation and dominant caste are Srinivas's; politicisation of caste is Kothari's; caste, class and power is Béteille's. A wrong attribution costs marks.
Do not say Article 15(2) binds only the State. It covers access to shops, hotels, wells and roads, including against private persons; Article 17 is the other provision that operates against private conduct.
Cite a figure for any ‘gap’ claim. NCRB 2023 or IHDS-II, with the year, makes the point; adjectives do not.

Frequently asked questions (FAQs)
What is the caste system in India?
A hereditary system that ranks social groups (jatis) by birth and regulates marriage, food and occupation through endogamy and purity-pollution rules. It differs from varna, the four-fold scriptural order.
What is the difference between Sanskritisation and Westernisation?
Sanskritisation is a lower caste adopting a higher caste's customs and rituals to rise in rank. Westernisation is change through contact with Western dress, technology, institutions and ideas. M.N. Srinivas described both.
What did Ambedkar say about caste?
In 1916 he identified endogamy as the feature peculiar to caste. In *Annihilation of Caste* (1936) he argued that caste rests on religious sanction and must be destroyed at that root.
Which Articles of the Constitution deal with caste?
Articles 15 and 16 bar discrimination, 17 abolishes untouchability, 46 protects weaker sections, 330 and 332 reserve legislative seats, and 341 provides for the list of Scheduled Castes.
Is caste discrimination banned abroad?
It varies. Seattle added caste to its anti-discrimination law in 2023, while California's statewide bill was vetoed the same year on the ground that existing categories already cover caste.
