Class: 12Subject: SociologyBook: Indian Society (Book I)Chapter: 3Title: Social Institutions: Continuity and ChangeSession: 2026–27
Chapter 3, Social Institutions: Continuity and Change, explores how a population becomes a society through the social institutions that bind people into classes and communities. It examines three institutions central to India: caste, tribe and family. The section on caste distinguishes varna and jati, lists the defining features of caste, and explains how the colonial census, surveys and the 1935 Government of India Act rigidified and reshaped caste, before tracing its changing role in independent India — in marriage, work, and especially politics, with concepts like sanskritisation and dominant caste (M.N. Srinivas). The section on tribes discusses how tribes are classified by permanent and acquired traits, debates the caste–tribe distinction, and weighs national development against tribal dispossession and identity assertion. The final section on family and kinship distinguishes nuclear and extended (joint) families and the rules of residence, descent and authority — matrilocal/patrilocal, matrilineal/patrilineal, patriarchy and the theoretical idea of matriarchy. Throughout, the theme is continuity and change: each institution survives, yet is continually reshaped by colonialism, modernity and democracy.
Key Concepts & Terms
Caste: an ancient social institution unique to the Indian sub-continent. The English word comes from the Portuguese casta (‘pure breed’); in Indian languages it is referred to by two terms, varna and jati.
Varna: literally ‘colour’; a four-fold all-India classification of society into brahmana, kshatriya, vaishya and shudra, with a fifth excluded category (the panchamas or ‘outcastes’).
Jati: a generic term for ‘kinds’ or ‘species’; the word most commonly used in Indian languages for caste, operating as a regional/local sub-classification of hundreds or thousands of castes and sub-castes.
Difference and hierarchy: the two principles underlying caste — each caste is different from and separated from every other, yet all castes exist only in relation to a hierarchical whole ranked from highest to lowest.
Purity and pollution: the ritual principle on which caste hierarchy is based; castes considered ritually pure have high status, those considered impure have low status.
Endogamy: the rule that marriage must take place within the caste group; this has been the most resilient feature of caste, largely unaffected by modernisation.
Segmental organisation: the way castes contain sub-castes, which may in turn contain further sub-divisions.
Sanskritisation: M.N. Srinivas’s concept for the process by which a (usually middle or lower) caste tries to raise its social status by adopting the ritual, domestic and social practices of a higher-status caste.
Dominant caste: M.N. Srinivas’s term for castes with large populations that gained land rights through post-Independence partial land reforms and thus acquired decisive economic and political power (e.g. Yadavs, Vokkaligas, Reddys, Marathas, Jats, Patidars).
Tribe: a modern term for some of the oldest communities of the sub-continent, defined negatively (no written-text religion, no normal state form, no sharp class divisions) and classified by ‘permanent’ traits (region, language, physical type, habitat) and ‘acquired’ traits (livelihood, degree of assimilation into Hindu society).
Family — nuclear and extended: a nuclear family has one set of parents and their children; an extended (joint) family has more than one couple and often more than two generations living together.
Matriliny vs matriarchy:matriliny is descent/inheritance traced through the mother (an empirically existing system); matriarchy means women exercising dominance and decision-making — a theoretical concept with no historical or anthropological evidence.
NCERT Exercise — Full Solutions
All questions below are reproduced verbatim from the NCERT textbook’s end-of-chapter Questions section. Answers are original, written in exam-ready style.
1. What is the role of the ideas of separation and hierarchy in the caste system?
ANSWERThe caste system can be understood as the combination of two sets of principles — one based on difference and separation and the other on wholism and hierarchy. These two ideas together give caste its distinctive form.Separation: Each caste is supposed to be different from, and is therefore strictly separated from, every other caste. Many of the scriptural rules of caste — covering marriage (endogamy), food and food-sharing, social interaction and occupation — are designed precisely to prevent the mixing of castes and to keep them apart.Hierarchy: These separated castes do not have an independent existence; they exist only in relation to a larger whole, the totality of society made up of all castes. This whole is not egalitarian but hierarchical — each caste occupies not just a distinct place but an ordered rank in a ladder-like arrangement from highest to lowest. The ranking is based on the opposition of purity and pollution: ritually pure castes are placed high, ritually impure castes low.Thus separation keeps castes distinct and self-contained, while hierarchy arranges these distinct units into a graded, unequal order. Together they made caste a system of difference that was simultaneously a system of inequality, also serving as a rigid social division of labour that allowed no mobility.
2. What are some of the rules that the caste system imposes?
ANSWERThe most commonly cited defining features — the rules that the caste system imposes — are the following:1. Determined by birth: Caste is decided by birth; a child is “born into” the caste of its parents. One can never choose, change or leave one’s caste, though a person may be expelled from it.2. Rules of marriage: Caste groups are endogamous — marriage is restricted to members of one’s own caste.3. Rules about food: There are strict rules about what kinds of food may or may not be eaten, and about whom one may share food with.4. Hierarchy of rank and status: Castes are arranged in a hierarchy; every person has a caste and every caste has a specified place in the ranking of all castes.5. Sub-divisions (segmental organisation): Castes almost always contain sub-castes, and these may have further sub-castes.6. Hereditary occupation: Castes were traditionally linked to occupations — one could practise only the occupation of one’s caste, occupations were passed from generation to generation, and members of other castes could not enter that occupation.These were prescribed rules found in ancient scriptural texts; since they were not always practised, they tell us the ideal pattern rather than the exact lived reality of caste.
3. What changes did colonialism bring about in the caste system?
ANSWERScholars agree that all major social institutions, and especially caste, underwent fundamental changes during the colonial period. Some even argue that caste as we know it today is more a product of colonialism than of ancient tradition. Not all these changes were intended or deliberate.Surveys and ethnology: To govern the country efficiently, British administrators conducted methodical surveys and reports on the ‘customs and manners’ of various castes and tribes; many officials were amateur ethnologists who pursued such studies.The census: The most important effort was the census. Begun in the 1860s and made a regular ten-yearly exercise from 1881, the 1901 Census under Herbert Risley tried to record the social hierarchy of caste — the rank order of each caste in particular regions. This had a huge impact: hundreds of petitions were sent to the Census Commissioner by castes claiming a higher position with historical and scriptural evidence. Counting and officially recording caste status changed the institution itself — identities that had been fluid and less rigid began to harden once they were counted.Legal recognition of schedules: The administration also took an interest in the welfare of the ‘depressed classes’. The Government of India Act of 1935 gave legal recognition to lists or ‘schedules’ of castes and tribes for special treatment — this is how the terms Scheduled Castes and Scheduled Tribes came into being.Alongside these direct interventions, the wider spread of capitalism and modernity during this period also reshaped caste. Overall, colonialism rigidified, recorded and reorganised caste, transforming it from a relatively fluid institution into the more fixed one familiar today.
4. In what sense has caste become relatively ‘invisible’ for the urban upper castes?
ANSWEROne of the most significant yet paradoxical changes of the contemporary period is that caste has tended to become ‘invisible’ for the upper-caste, urban middle and upper classes — while remaining all too visible for the lower castes.For these privileged groups, caste appears to have declined in significance precisely because it has done its job so well. Their caste status had earlier ensured that they possessed the economic and educational resources needed to take full advantage of post-Independence development — subsidised public and professional education (in science, technology, medicine and management) and the expansion of public-sector jobs. With this head start, they faced no serious competition.By the second and third generations, this advantage had become consolidated into economic and educational capital that was, by itself, enough to secure the best life chances. As a result, these groups began to believe that their advancement had little to do with caste. Caste now seems to play no part in their public lives, being confined to the personal sphere of religion, marriage and kinship.In this sense caste is ‘invisible’ for them — not because it has disappeared, but because its work of securing privilege is already done and is now sustained by class advantages. (A further complication is that although the privileged are overwhelmingly upper caste, not all upper-caste people are privileged; some are poor.)
5. How have tribes been classified in India?
ANSWERIn terms of positive characteristics, tribes in India have been classified according to their ‘permanent’ and ‘acquired’ traits.Permanent traits include:• Region: the tribal population is dispersed but concentrated — about 85% live in ‘middle India’ (a band from Gujarat and Rajasthan to West Bengal and Odisha), over 11% in the North-Eastern states, and just over 3% in the rest of India.• Language: tribes fall into four categories — Indo-Aryan and Dravidian (shared with the wider population) and Austric and Tibeto-Burman (primarily tribal).• Physical-racial type: Negrito, Australoid, Mongoloid, Dravidian and Aryan categories.• Ecological habitat: hills, forests, rural plains and urban-industrial areas.Acquired traits use two main criteria: mode of livelihood — classifying tribes as fishermen, food gatherers and hunters, shifting cultivators, peasants, and plantation/industrial workers — and the extent of incorporation into Hindu society, which is the dominant classification in academic sociology and public affairs. Assimilation may be seen from the tribes’ own point of view (including their attitude towards Hinduism, whether favourable or resistant) or, more commonly, from the mainstream point of view (the status accorded to them within Hindu society).
6. What evidence would you offer against the view that ‘tribes are primitive communities living isolated lives untouched by civilisation’?
ANSWERThe idea that tribes are like stone-age hunting-and-gathering societies untouched by time is common but has not been true for a long time. Several pieces of evidence contradict it:1. Long contact and absorption: Throughout Indian history tribes have been absorbed into Hindu society — through sanskritisation, acceptance into the Shudra fold after conquest, and acculturation. This shows continuous interaction, not isolation.2. Tribes were not always oppressed: Adivasis were not always the powerless groups they are now. There were several Gond kingdoms in Central India (such as Garha Mandla and Chanda), and many so-called Rajput kingdoms actually emerged through stratification within adivasi communities themselves.3. Power over the plains and trade: Adivasis often exercised dominance over plains people through their capacity to raid them and through service as local militias. They also occupied a special trade niche, trading in forest produce, salt and elephants.4. Settled agriculture and specialisation: Tribes like the Munda and Hos turned to settled agriculture long ago, and even hunting-gathering tribes like the Birhors employed specialised households to make baskets and press oil.5. Early integration into the capitalist economy: The capitalist drive to exploit forests and minerals and to recruit cheap labour brought tribal societies into contact with the mainstream a long time ago.6. ‘Secondary’, not pristine: Some scholars argue there is no coherent basis for treating tribes as ‘pristine’ societies uncontaminated by civilisation; they are better seen as ‘secondary’ phenomena arising out of contact between pre-existing states and non-state groups. All this evidence shows that tribes were neither primitive nor isolated.
7. What are the factors behind the assertion of tribal identities today?
ANSWERTribal identities today are formed by an interactional process with the mainstream rather than by any primordial (ancient, original) characteristics. Because this interaction has generally been on terms unfavourable to tribes, many tribal identities are now centred on resistance and opposition to the non-tribal world. The main factors are:1. Dispossession and unfavourable incorporation: Forced incorporation into mainstream processes — loss of land and forests, and a disproportionate price paid for national development (dams, mines, factories) — has fed resentment and the assertion of identity.2. In-migration of non-tribals: Heavy in-migration (as in Jharkhand’s industrial areas and dramatically in the North-East, where Tripura’s tribal share was halved in a decade) threatens to overwhelm tribal communities and cultures, sharpening identity.3. Control over economic resources: Issues relating to control over vital resources, especially land and forests, are a major trigger for tribal movements.4. Ethnic-cultural identity: Matters of culture, tradition and ethnic identity form the second broad set of issues; successes such as statehood for Jharkhand and Chhattisgarh have also energised assertion.5. The emergence of an educated middle class: Modern education and occupations, aided by reservation policies, have produced a tribal middle class (most visible in the North-East). This class brings a new consciousness, raising issues of culture, livelihood, land and a share in the benefits of modernity.As tribal society becomes more differentiated, the reasons the middle class asserts tribal identity may differ from those of poorer, uneducated tribals — and the interplay of these internal dynamics with external forces shapes tribal identity today.
8. What are some of the different forms that the family can take?
ANSWERThe family can be studied as a social institution in itself and in its relationship to other institutions. As an institution in itself, it takes a number of different forms:By composition: a family may be nuclear (one set of parents and their children) or extended/joint (more than one couple and often more than two generations living together — for example, a set of brothers with their families, or an elderly couple with their sons, grandsons and their families).By authority: a family may be male-headed or female-headed — for instance, the migration of men from Himalayan villages can produce an unusually high proportion of women-headed families.By rule of residence: a family may be matrilocal (the newly married couple stays with the woman’s parents) or patrilocal (the couple lives with the man’s parents).By rule of descent/inheritance: a family may be matrilineal (property passes from mother to daughter) or patrilineal (property passes from father to son).By structure of authority: a family may be patriarchal (men exercise authority and dominance) or, in theory, matriarchal (women dominate). These forms also change over time in relation to political, economic, cultural and educational changes in the wider society.
9. In what ways can changes in social structure lead to changes in the family structure?
ANSWERThe family (the private sphere) is closely linked to the economic, political, cultural and educational (public) spheres, so changes in the wider social structure can directly reshape the family. These changes may be accidental or purposive.Accidental/structural changes: When the structures of society change, the composition of the family changes with them. For example, the migration of men from the villages of the Himalayan region (an economic change) can lead to an unusually high proportion of women-headed families in those villages. Similarly, the demanding work schedules of young parents in India’s software industry may lead to grandparents moving in as care-givers for young grandchildren, changing the structure of the household.Wars and large-scale migration in search of work also alter family forms without anyone intending it.Purposive changes: Some changes are deliberately brought about — for example, when young people decide to choose their own spouses instead of letting elders decide, or when same-sex love is expressed openly in society. Such changes alter not only family structures but also the cultural ideas, norms and values attached to family.Thus the family does not exist in isolation: economic, political and cultural transformations in society continually reshape who lives together, who heads the household, and the norms that govern family life — though such changes are often resisted, sometimes violently.
10. Explain the difference between matriliny and matriarchy.
ANSWERMatriliny refers to a system of descent and inheritance traced through the mother — in matrilineal societies property passes from mother to daughter. Matriliny is an empirically existing arrangement; such societies do exist. Importantly, however, even in matrilineal societies women inherit property but do not necessarily exercise control over it, nor are they the decision-makers in public affairs.Matriarchy, by contrast, refers to a system in which women actually exercise authority and dominance — the mirror image of patriarchy. Unlike patriarchy, matriarchy has been a theoretical rather than an empirical concept: there is no historical or anthropological evidence of any society in which women exercise such dominance.The key difference: matriliny is about the line of inheritance/descent (through the mother) and does exist; matriarchy is about the exercise of power (by women) and has never been found to exist. A society can be matrilineal without being matriarchal, because tracing property through the mother does not mean women hold actual power or control.
Extra Practice Questions
Short Answer Type Questions
Q1. Distinguish between varna and jati.
ANSWERVarna (literally ‘colour’) is a broad, all-India four-fold classification of society into brahmana, kshatriya, vaishya and shudra (with the excluded panchamas as a fifth category). Jati is a regional or local sub-classification involving hundreds or thousands of castes and sub-castes; it is the word most commonly used for caste in Indian languages. The common interpretation treats varna as the aggregative all-India scheme and jati as the more complex local hierarchy.
Q2. What is meant by the ‘purity and pollution’ principle in the caste system?
ANSWERThe hierarchical ordering of castes is based on the distinction between ‘purity’ (closeness to the sacred, hence ritual purity) and ‘pollution’ (distance from or opposition to the sacred). Castes considered ritually pure are given high status, while those considered impure are given low status. Since material power is closely linked to social status, those in power tended to be high-status, and the defeated were often assigned low caste status.
Q3. Who was M.N. Srinivas and what two concepts is he known for?
ANSWERMysore Narasimhachar Srinivas (1916–1999) was one of India’s foremost sociologists and social anthropologists, known for his work on the caste system and his village study The Remembered Village. He contributed two influential concepts: sanskritisation (a lower/middle caste raising its status by imitating a higher caste’s practices) and dominant caste (a numerically large caste with land rights and decisive local power).
Q4. Why were the terms ‘Scheduled Castes’ and ‘Scheduled Tribes’ created?
ANSWERAs part of colonial efforts towards the welfare of the ‘depressed classes’, the Government of India Act of 1935 gave legal recognition to lists or ‘schedules’ of castes and tribes marked out for special treatment by the state. Castes at the bottom of the hierarchy, including all the so-called ‘untouchable’ castes, were placed among the Scheduled Castes — and so these official categories came into being.
Q5. Why has caste become ‘all too visible’ for the Scheduled Castes, Scheduled Tribes and backward castes?
ANSWERFor these groups the opposite of ‘invisibility’ has happened. Because they have no inherited educational or social capital and must compete with an entrenched upper-caste group, they cannot abandon their caste identity — it is one of the few collective assets they have. They continue to suffer discrimination, and the policies of reservation and protective discrimination serve as their lifelines. But relying on this lifeline tends to make caste the all-important and often the only aspect of their identity that the world recognises.
Long Answer Type Questions
Q1. Trace how caste changed across the past, the colonial period and the present.
ANSWERIn its earliest phase, in the late Vedic period (roughly 900–500 BC), caste was really a varna system of only four divisions; these were not very elaborate or rigid, were not determined by birth, and movement across categories was common. Only in the post-Vedic period did caste become the rigid, birth-based institution defined by endogamy, food rules, hierarchy and hereditary occupation. During the colonial period, caste underwent fundamental change: British surveys, the census (especially Risley’s 1901 Census recording caste rank), and the Government of India Act of 1935 counted, recorded and rigidified caste, while capitalism and modernity reshaped it — so much so that some scholars call caste a product of colonialism. In the present, Independence brought a partial break: the Constitution committed the state to abolishing caste, urbanisation and modern industry created caste-free jobs, and educated Indians abandoned extreme practices — yet caste proved resilient. Industrial recruitment ran along caste lines, endogamy survived, and caste became central to electoral politics, even spawning caste-based parties. Caste thus shows both continuity and change: it persists, but in continually transformed forms.
Q2. Explain Srinivas’s concepts of ‘sanskritisation’ and ‘dominant caste’ with examples.
ANSWERTo understand processes of change in caste, sociologists coined new concepts, two of the most common being ‘sanskritisation’ and ‘dominant caste’, both contributed by M.N. Srinivas. Sanskritisation refers to a process by which members of a (usually middle or lower) caste attempt to raise their social status by adopting the ritual, domestic and social practices of a caste of higher status — for example, taking up vegetarianism, teetotalism or higher-caste rituals to claim a better rank. Dominant caste refers to castes that had a large population and were granted land rights by the partial land reforms after Independence. Land reforms took rights away from the upper-caste ‘absentee landlords’ (who lived in towns and merely collected rent) and vested them in the next layer — the intermediate castes who managed agriculture. With land rights came economic power, and their large numbers gave them political power under universal adult franchise. They thus became the ‘dominant’ castes in the countryside, decisive in regional politics and the agrarian economy. Examples include the Yadavs of Bihar and Uttar Pradesh, the Vokkaligas of Karnataka, the Reddys and Khammas of Andhra Pradesh, the Marathas of Maharashtra, the Jats of Punjab, Haryana and Western U.P., and the Patidars of Gujarat.
Q3. Discuss the conflict between national development and tribal development.
ANSWERThe imperatives of ‘development’ have shaped the state’s attitude towards tribes. National development, particularly in the Nehruvian era, meant building large dams, factories and mines. Because tribal areas lay in the mineral-rich and forest-covered parts of the country, tribals paid a disproportionate price for the development of the rest of Indian society — this kind of development benefited the mainstream at the tribes’ expense. Tribals were dispossessed of their land as a by-product of mining and of building hydroelectric plants on favourable sites in tribal regions. The loss of forests, on which most tribal communities depended, was a major blow; forests began to be systematically exploited in British times and the trend continued after Independence, while the coming of private property disadvantaged community-based collective ownership. In addition, heavy in-migration of non-tribals in response to development pressures has threatened to overwhelm tribal communities — the industrial areas of Jharkhand saw the tribal share of population diluted, and in the North-East, Tripura’s tribal share was halved within a single decade, reducing them to a minority. Thus national development and tribal welfare have frequently been in conflict, feeding tribal movements over land, forests and identity.

Exam Tips & Common Mistakes
How to score full marks in this chapter
Anchor every caste answer in the twin principles of separation and hierarchy, and learn the six defining features of caste in order. For colonialism, remember the trio — surveys, the 1901 Risley census, and the 1935 Act. Keep the period framework (ancient → colonial → present) ready for ‘continuity and change’ questions. Define sanskritisation and dominant caste precisely and always attribute them to M.N. Srinivas, with examples (Yadavs, Vokkaligas, Marathas, Jats, Patidars). For tribes, separate permanent from acquired traits, and use concrete evidence (Gond kingdoms, Munda settled agriculture, forest trade) against the ‘isolated/primitive’ view. For family, keep the residence/descent/authority pairs distinct, and never confuse matriliny (exists) with matriarchy (no evidence).
Common mistakes to avoid
Confusing varna (broad all-India scheme) with jati (local sub-classification).
Saying the caste system stayed the same for 3,000 years — in the late Vedic period it was a simpler varna system, not birth-based or rigid.
Confusing matriliny (descent/inheritance through the mother) with matriarchy (rule by women, which has no evidence).
Mixing up matrilocal/patrilocal (rule of residence) with matrilineal/patrilineal (rule of descent).
Calling tribes ‘primitive’ or ‘isolated’ — the chapter gives clear evidence against this.
Forgetting that caste becoming ‘invisible’ for the upper castes means it succeeded, not that it disappeared.
Frequently Asked Questions
What is Chapter 3 of Class 12 Sociology (Indian Society) about?
Chapter 3, Social Institutions: Continuity and Change, studies three institutions central to Indian society — caste, tribe and family — and traces how each has both continued and changed across the ancient, colonial and post-Independence periods, including concepts like sanskritisation, dominant caste, and the difference between matriliny and matriarchy.
What is the difference between matriliny and matriarchy?
Matriliny is a system of descent and inheritance traced through the mother, where property passes from mother to daughter; it exists in reality but women do not necessarily control the property. Matriarchy means women actually exercising dominance and decision-making; it is only a theoretical concept, with no historical or anthropological evidence of any such society.
Who gave the concepts of sanskritisation and dominant caste?
Both concepts were contributed by the sociologist M.N. Srinivas. Sanskritisation is the process by which a lower or middle caste raises its status by adopting the practices of a higher-status caste, while a dominant caste is a numerically large caste that gained land rights after Independence and thus acquired economic and political power.
