Class: 12Subject: HistoryBook: Themes in Indian History (Part I)Chapter: 1 (Theme One)Title: Bricks, Beads and BonesSession: 2026–27
Chapter 1, Bricks, Beads and Bones, explores the Harappan or Indus Valley Civilisation (c. 2600–1900 BCE for the Mature Harappan phase) through its archaeology. It opens with the famous Harappan seal of steatite and explains that, because the script remains undeciphered, our knowledge comes almost entirely from material evidence. The chapter examines Harappan subsistence strategies (grains, animals, agricultural technologies), the planned city of Mohenjodaro with its Citadel, Lower Town, grid streets, standardised bricks, drainage system and the Great Bath, and how archaeologists track social differences through burials and luxuries. It studies craft production at sites like Chanhudaro, the procurement of raw materials from across the subcontinent and from Oman, Dilmun and Mesopotamia (Meluhha), and the system of seals, script and weights. It asks who held authority in Harappan society, traces the end of the civilisation around 1900 BCE, and finally narrates how the civilisation was discovered by Cunningham, Sahni, Banerji, Marshall and Wheeler, ending with the problems of interpreting the archaeological record.
Key Terms & Concepts
Harappan Civilisation: the Bronze Age urban civilisation of the Indus and Saraswati basins, named after Harappa, the first site discovered. Its Mature (urban) phase is dated c. 2600–1900 BCE.
Citadel and Lower Town: Mohenjodaro and most Harappan cities were divided into a smaller but higher western part (the Citadel, built on mud-brick platforms and walled) and a larger but lower eastern part (the Lower Town, the residential area).
Standardised bricks: whether sun-dried or baked, Harappan bricks followed a uniform ratio where length and breadth were four times and twice the height respectively — used at all settlements, a sign of central control.
Drainage system: a carefully planned network in which streets and drains were laid first and houses built along them; every house was connected to street drains that emptied through sumps, “the most complete ancient system as yet discovered.”
The Great Bath: a large watertight rectangular tank on the Citadel of Mohenjodaro, made leak-proof with bricks set on edge in gypsum mortar; scholars think it was used for a special ritual bath.
Utilitarian vs luxuries: archaeologists classify artefacts of daily use made of ordinary materials (querns, pottery, needles) as utilitarian, and rare objects of costly, non-local materials or complex technology (faience pots, gold jewellery) as luxuries.
Meluhha: the name by which Mesopotamian texts probably referred to the Harappan region; its listed products included carnelian, lapis lazuli, copper, gold and varieties of wood, and it was described as a land of seafarers.
Seals, sealings and script: seals (often with an animal motif and writing) were pressed on wet clay (a sealing) to secure goods and convey the sender’s identity; the script, with 375–400 signs, was written right to left and is still undeciphered.
Weights: a precise system, generally of cubical chert; lower denominations were binary (1, 2, 4, 8, 16, 32) and higher ones decimal (160, 200, 320, 640).
Stratigraphy: the study of the layers of an archaeological mound; generally the lowest layers are the oldest and the highest the most recent, helping assign artefacts to cultural periods.
Archaeogenetics: the study of the DNA of ancient populations; recent research at Rakhigarhi (Haryana, the biggest Harappan city) indicates the Harappans were indigenous to the region.

All questions below are reproduced verbatim from the NCERT textbook end-of-chapter exercise. Answers are original, written in CBSE exam-ready style. Figure and map questions are answered in words, as no textbook images are reproduced here.
Answer in 100–150 words
1. List the items of food available to people in Harappan cities. Identify the groups who would have provided these.
ANSWERThe Harappans ate a wide range of plant and animal products. Plant foods reconstructed from charred grains and seeds include wheat, barley, lentil, chickpea and sesame; millets are found at sites in Gujarat, while finds of rice are relatively rare.Animal foods came from cattle, sheep, goat, buffalo and pig, which archaeo-zoologists have shown were domesticated. Bones of wild species such as boar, deer and gharial, and of fish and fowl, are also found.The groups who provided these: farmers grew the grains, pulses and oilseeds; pastoralists reared and supplied the domesticated cattle, sheep and goats and gave milk and meat; fishing communities supplied fish and fowl. The wild meat may have been obtained by the Harappans hunting themselves or through exchange with specialised hunting and gathering communities living near the settlements.
2. How do archaeologists trace socio-economic differences in Harappan society? What are the differences that they notice?
ANSWERArchaeologists use two main strategies. (a) Studying burials: the dead were generally laid in pits; sometimes the pit was lined with bricks, which may indicate social difference, though this is not certain. Some graves contain pottery and ornaments (and in one case copper mirrors), and an ornament of three shell rings, a jasper bead and hundreds of micro beads was found near a male skull at Harappa. On the whole, however, the Harappans did not bury precious things with the dead, so burials show little differentiation.(b) Studying artefacts (“luxuries”): archaeologists classify objects as utilitarian (everyday items of ordinary stone or clay) or luxuries (rare items of costly, non-local materials or complex technology, such as little faience pots). Such rare valuable objects are concentrated in large cities like Mohenjodaro and Harappa and are rare in small settlements like Kalibangan; all the gold jewellery was found in hoards. These patterns suggest that some social and economic differences existed, even if they were not sharply marked.
3. Would you agree that the drainage system in Harappan cities indicates town planning? Give reasons for your answer.
ANSWERYes, the drainage system clearly indicates careful town planning. The roads and streets of the Lower Town were laid out on an approximate grid pattern, intersecting at right angles, and it seems that streets with drains were laid out first and houses built later along them. To let domestic waste water flow into the street drains, every house needed at least one wall along a street — showing that drains and houses were planned together.Every house was connected to the street drains; the main channels were of brick set in mortar, covered with loose bricks (or limestone slabs) that could be lifted for cleaning, and house drains emptied into sumps or cesspits where solids settled before water flowed out. Long channels had sumps at intervals for cleaning. Such systems existed even in smaller settlements like Lothal, where houses were of mud brick but drains of burnt brick. This deliberate, standardised, city-wide arrangement could only result from advance planning.
4. List the materials used to make beads in the Harappan civilisation. Describe the process by which any one kind of bead was made.
ANSWERMaterials used for beads: a remarkable variety — stones such as carnelian (a beautiful red), jasper, crystal, quartz and steatite; metals such as copper, bronze and gold; and shell, faience and terracotta (burnt clay). Some beads combined two or more stones cemented together, and some stone beads had gold caps. Shapes were numerous — disc-shaped, cylindrical, spherical, barrel-shaped and segmented — and some were decorated by incising, painting or etching designs.Process for making a carnelian bead: the beautiful red colour of carnelian was obtained by firing the yellowish raw material and the beads at various stages of production. Nodules were first chipped into rough shapes, then finely flaked into the final form. The bead was then completed by grinding, polishing and drilling. Specialised cylindrical drills used for this have been found at Chanhudaro, Lothal and Dholavira.
5. Look at Fig. 1.30 and describe what you see. How is the body placed? What are the objects placed near it? Are there any artefacts on the body? Do these indicate the sex of the skeleton?
ANSWERFig. 1.30 shows a typical Harappan burial. The dead body has been laid in a pit dug into the ground, placed in an extended position lying on its back, with the head usually towards the north. This was the common Harappan mode of disposing of the dead.Objects placed near it: a number of pots (pottery vessels) have been arranged around the body, probably containing food and water, perhaps reflecting a belief that these could be used by the dead in the afterlife.Artefacts on the body: some ornaments or jewellery may be seen, since jewellery has been found in the burials of both men and women. Because jewellery in Harappan burials was worn by both sexes, the artefacts on the body do not by themselves indicate whether the skeleton is male or female; the sex can be determined only by scientific examination of the skeleton itself, not from the grave goods.

6. Describe some of the distinctive features of Mohenjodaro.
ANSWERMohenjodaro, the best-known Harappan site, is the finest example of a planned urban centre and shows several distinctive features.1. Two-part layout: the settlement was divided into two sections — a smaller but higher western part called the Citadel and a much larger but lower eastern part called the Lower Town. The Citadel owed its height to buildings raised on mud-brick platforms and was walled, physically separating it from the Lower Town.2. Planning and standardised bricks: the Lower Town too was walled and many buildings stood on platforms used as foundations — an enormous labour effort (an estimated four million person-days just for the foundations). Once platforms were in place, building was confined to fixed areas, showing the city was first planned and then built. Bricks, whether sun-dried or baked, were of a standardised ratio (length and breadth four and two times the height).3. Grid streets and drainage: roads and streets followed an approximate grid, intersecting at right angles. Streets with drains were laid first; every house connected to the covered street drains, which had sumps for cleaning — one of the most complete ancient drainage systems known.4. Domestic architecture: houses were centred on a courtyard with rooms around it, with an apparent concern for privacy — no ground-level windows and a main entrance that did not give a direct view of the interior. Every house had a brick-paved bathroom with drains; many had staircases to an upper storey and wells (Mohenjodaro had about 700 wells).5. Special structures on the Citadel: these include the warehouse (a massive brick structure) and the Great Bath, a watertight rectangular tank in a courtyard surrounded by a corridor, with steps on the north and south, rooms around it (one with a large well), and a smaller building of eight bathrooms across a lane. The uniqueness of the Great Bath suggests it was meant for a special ritual bath. A large building was labelled a “palace,” and a stone statue the “priest-king.” These features together make Mohenjodaro a remarkable example of early urban planning.
7. List the raw materials required for craft production in the Harappan civilisation and discuss how these might have been obtained.
ANSWERRaw materials required: Harappan crafts used clay (locally available), and a range of materials brought from outside the alluvial plain — stones such as carnelian, jasper, crystal, quartz and steatite; metals such as copper, bronze and gold; shell; faience; lapis lazuli; timber; and chert for weights. These were used for bead-making, shell-cutting, metal-working, seal-making and weight-making, as at the craft centre of Chanhudaro.How they were obtained: the Harappans used several strategies.(1) Settling near sources: they established settlements where raw material was available — Nageshwar and Balakot near the coast for shell; Shortughai in far-off Afghanistan near the best source of lapis lazuli; and Lothal near sources of carnelian (Bharuch), steatite (south Rajasthan and north Gujarat) and metal (Rajasthan).(2) Sending expeditions: they sent expeditions to regions such as the Khetri area of Rajasthan (for copper) and south India (for gold). These expeditions established communication with local communities; occasional finds of Harappan artefacts (like steatite micro beads) in these areas show such contact. The Ganeshwar–Jodhpura culture of the Khetri region, rich in copper, may have supplied copper to the Harappans.(3) Long-distance trade: copper was probably also brought from Oman (Magan) — both Omani and Harappan copper carry traces of nickel, suggesting a common origin, and a distinctive black-coated Harappan jar found in Oman points to exchange. Mesopotamian texts mention contact with Dilmun (Bahrain), Magan and Meluhha (the Harappan region), listing products such as carnelian, lapis lazuli, copper, gold and wood. Communication was probably by sea, since Meluhha was described as a land of seafarers and ships and boats appear on seals.
8. Discuss how archaeologists reconstruct the past.
ANSWERBecause the Harappan script is undeciphered, archaeologists reconstruct the past mainly from material evidence — pottery, tools, ornaments, household objects, seals, bricks and bones. Since organic materials (cloth, leather, wood, reeds) decay, what survives is largely stone, terracotta and metal, and intact valuable finds are accidental rather than typical, so reconstruction is always partial.Recovery and classification: after recovering artefacts, archaeologists classify them — first by material (stone, clay, metal, bone, ivory) and then, more difficultly, by function (tool, ornament, ritual object, or several at once). Function is judged by an artefact’s resemblance to present-day objects and by the context in which it was found — in a house, a drain, a grave or a kiln. Where direct evidence is lacking (for example, clothing), they rely on indirect evidence such as depictions in sculpture.Using analogies and frames of reference: archaeologists move from the known to the unknown, using present-day analogies (as Mackay compared ancient querns with modern ones). This works well for everyday objects but becomes speculative for religious symbols — for instance, the “proto-Shiva” seal and “mother goddess” figurines rest on assuming later traditions parallel earlier ones, and the figure does not match Rudra of the Rigveda.Reconstructing economy and society: dietary practices are inferred from charred grains by archaeo-botanists and from bones by archaeo-zoologists; social differences from burials and luxuries; crafts from waste, tools, unfinished objects and rejects.Strategies of excavation: the value of method is clear from history — Marshall excavated in uniform horizontal units, ignoring stratigraphy, so context was lost, whereas Wheeler followed the natural stratigraphy of the mound, where lower layers are older. Today archaeologists also use modern scientific techniques such as surface exploration and archaeogenetics (DNA analysis at Rakhigarhi). Careful re-examination of data can even reverse earlier conclusions, as when George Dales disproved the “massacre” at Mohenjodaro.
9. Discuss the functions that may have been performed by rulers in Harappan society.
ANSWERThere are clear indications of complex decision-making in Harappan society, even though direct evidence of rulers is scarce. The extraordinary uniformity of artefacts — pottery, seals, weights and especially bricks of a uniform ratio from Jammu to Gujarat — suggests that some authority laid down and enforced common standards.Functions a ruler/authority may have performed: (1) Standardising production: enforcing the uniform ratio of bricks, the precise weight system and the common artefact types across a vast region. (2) Planning settlements: settlements were strategically located near sources of raw material and water; cities were planned with citadels, grid streets and drains, implying coordinated decisions. (3) Mobilising labour: labour was organised on a huge scale to make bricks and build massive walls and platforms (millions of person-days). (4) Organising trade and procurement: establishing settlements near raw materials and sending expeditions to distant regions for copper and gold required organisation.Debate over who ruled: archaeology gives no clear centre of power. A building at Mohenjodaro was called a “palace” but had no spectacular finds; a stone statue is called the “priest-king,” on the analogy of Mesopotamian priest-kings, but we cannot be sure ritual specialists held political power. Scholars differ: some think there were no rulers and everyone had equal status; some think there were several rulers (Mohenjodaro one, Harappa another); others argue for a single state, given the uniformity of artefacts, planned settlements, standardised bricks and organised procurement. The text suggests the Harappans may have practised some sort of democratic system, with many structures serving utilitarian purposes.
Map work
10. On Map 1, use a pencil to circle sites where evidence of agriculture has been recovered. Mark an X against sites where there is evidence of craft production and R against sites where raw materials were found.
ANSWER (described in words)This is a map-marking activity. On an outline of Map 1, identify and mark the sites as follows, using the evidence given in the chapter:Circle (evidence of agriculture): Kalibangan (a ploughed field with furrows at right angles), Banawali and sites in Cholistan (terracotta models of the plough), and Dholavira (water reservoirs for agriculture). Grains and agricultural evidence are widespread, so cities such as Harappa and Mohenjodaro can also be circled.Mark X (evidence of craft production): Chanhudaro (bead-making, shell-cutting, metal-working, seal-making, weight-making), Lothal (beads and specialised drills), Nageshwar and Balakot (shell objects), Dholavira (specialised drills), and the large cities Mohenjodaro and Harappa.Mark R (sources of raw materials): Nageshwar and Balakot (shell), Shortughai in Afghanistan (lapis lazuli), the Khetri region of Rajasthan (copper, near Lothal/inland), and sources near Lothal — Bharuch (carnelian) and south Rajasthan/north Gujarat (steatite). (Locate each site on your textbook Map 1 and mark accordingly.)
Project (any one)
11. Find out if there are any museums in your town. Visit one of them and write a report on any ten items, describing how old they are, where they were found, and why you think they are on display.
ANSWER (project guidance)This is a project to be done by the student through a real museum visit; answers will vary. How to do it: find a museum in your town or district (a state museum, an ASI site museum or a local heritage museum). Visit it, note any ten exhibits, and for each record its name, approximate age or period, the site or region where it was found, the material it is made of, and your reason why it is on display (its historical, artistic or scientific importance).Format of the report: write a short introduction (name and location of the museum), then a numbered list or table of the ten items with the details above, and a brief conclusion on what the visit taught you. If you live near a Harappan site museum, such as the one at Lothal or the National Museum, Delhi, you may report on Harappan beads, pottery, seals and tools. (Use your own observations from the museum you actually visit.)
12. Collect illustrations of ten things made of stone, metal and clay produced and used at present. Compare these with the pictures of the Harappan civilisation in this chapter, and discuss the similarities and differences that you find.
ANSWER (project guidance)This is a comparison project; answers will vary. How to do it: collect or draw illustrations of ten present-day objects made of stone, metal and clay — for example a stone grinding quern, a metal pot, a clay water pot, beads, a needle, a mirror and toys. Place each beside the comparable Harappan object pictured in the chapter (saddle quern, copper and bronze vessels, pottery, carnelian beads, copper tools, copper mirror, terracotta cart).What to discuss: note the similarities — many forms have continued for thousands of years, such as querns for grinding, earthen pots, beads and bullock carts, showing remarkable continuity in everyday life. Note the differences — modern objects use new materials (steel, plastic, electricity-driven machines) and mass production, whereas Harappan objects were hand-made from stone, copper, bronze and terracotta. Conclude with what this tells you about technology, craft and daily life then and now. (Present your own collected illustrations and observations.)
Extra Practice Questions
Short Answer Type Questions
Q1. Why is the Harappan script described as ‘enigmatic’?
ANSWERThe script is called enigmatic because it remains undeciphered. It was not alphabetical, as it has too many signs (between 375 and 400), most inscriptions are short (the longest about 26 signs), and it was written from right to left. We cannot read the names, titles or language of the Harappans, which is why archaeologists depend on material evidence instead.
Q2. What were seals and sealings used for?
ANSWERSeals and sealings facilitated long-distance communication and trade. The mouth of a bag of goods was tied with rope, wet clay was placed on the knot, and a seal pressed into it left an impression (a sealing). If the bag arrived with its sealing intact, it showed the goods had not been tampered with, and the sealing also conveyed the identity of the sender.
Q3. What was the Harappan system of weights like?
ANSWERExchanges were regulated by a precise system of weights, usually made of a stone called chert and generally cubical with no markings. The lower denominations were binary (1, 2, 4, 8, 16, 32) and the higher denominations decimal (160, 200, 320, 640). The smaller weights were probably used for weighing jewellery and beads, and metal scale-pans have also been found.
Q4. What does archaeogenetic research at Rakhigarhi suggest?
ANSWERDNA extracted from skeletal remains at Rakhigarhi (the biggest Harappan city, in Haryana) indicates that the Harappans were the indigenous people of the region, with genetic roots going back to about 10,000 BCE and continuity to the present day. The study found no ancestry from steppe pastoralists or Iranian farmers, suggesting unbroken genetic and cultural continuity rather than large-scale immigration.
Q5. How did George Dales question the theory of a ‘massacre’ at Mohenjodaro?
ANSWERR.E.M. Wheeler had argued that an Aryan invasion (“Indra stands accused”) destroyed the city. In the 1960s George Dales showed the skeletons did not belong to the same period; there was no destruction level, no sign of extensive burning, no warriors in armour, and the fortified citadel showed no evidence of a final defence. He demonstrated that the “massacre” was a myth, showing how re-examining data can reverse earlier interpretations.
Long Answer Type Questions
Q1. Describe the agricultural technologies of the Harappans and the evidence for them.
ANSWERThe prevalence of agriculture is shown by finds of grain (wheat, barley, lentil, chickpea, sesame and, in Gujarat, millets), but actual farming practices are harder to reconstruct. Representations of the bull on seals and terracotta sculpture lead archaeologists to infer that oxen were used for ploughing, and terracotta models of the plough have been found in Cholistan and at Banawali (Haryana). A ploughed field at Kalibangan, with two sets of furrows at right angles, suggests two crops were grown together. For harvesting, the Harappans may have used stone blades set in wooden handles or metal tools. Because most sites lie in semi-arid lands, irrigation was probably needed: traces of canals occur at Shortughai in Afghanistan (though not in Punjab or Sind, perhaps because canals silted up), water was likely drawn from wells, and the reservoirs at Dholavira may have stored water for agriculture. Thus a range of evidence — seals, terracotta models, fields, tools and water structures — is used to reconstruct Harappan agriculture.
Q2. Trace how the Harappan civilisation was discovered by archaeologists.
ANSWERWhen Harappan cities fell into ruin, people forgot them, and later inhabitants did not understand the strange artefacts that surfaced. Cunningham’s confusion: Alexander Cunningham, the first Director-General of the ASI, focused on the Early Historic period and used the accounts of Chinese pilgrims; a Harappan seal given to him could not be placed in his time-frame, and he missed Harappa’s significance because he believed Indian history began with the Ganga-valley cities. A new old civilisation: in the early twentieth century Daya Ram Sahni found seals at Harappa in layers older than Early Historic levels, and Rakhal Das Banerji found similar seals at Mohenjodaro, suggesting a single culture. In 1924 John Marshall, Director-General of the ASI, announced the discovery of the Indus civilisation to the world; matching seals at Mesopotamian sites showed it was contemporaneous with Mesopotamia. Marshall, the first professional archaeologist in India, looked for patterns of everyday life but excavated in uniform horizontal units, ignoring stratigraphy and losing context. New techniques: R.E.M. Wheeler, taking over in 1944, corrected this by following the stratigraphy of the mound with military precision. After Partition the major sites went to Pakistan, spurring Indian archaeologists to find sites such as Kalibangan, Lothal, Rakhigarhi and Dholavira, and since the 1980s international teams have used modern scientific techniques.
Q3. Explain the problems archaeologists face in interpreting Harappan religion.
ANSWERInterpreting Harappan religion is among the hardest tasks because there are no readable texts and unfamiliar objects are easily misread. Early archaeologists assigned religious significance to unusual finds: heavily jewelled terracotta female figurines were called “mother goddesses”; standardised seated stone statues of men, such as the “priest-king,” were similarly classified; structures like the Great Bath and the fire altars at Kalibangan and Lothal were given ritual meaning; seals with plant motifs were read as nature worship; and conical stone objects were called lingas. A figure seated cross-legged in a “yogic” posture surrounded by animals was identified as “proto-Shiva.” The basic problem is that such reconstructions assume later traditions parallel earlier ones, moving from the known present to the unknown past — reasonable for querns and pots but speculative for religious symbols. For example, the Rigvedic god Rudra (later identified with Shiva) is not described as Pashupati or as a yogi, so the “proto-Shiva” identification does not match the text; the figure might even be a shaman. Similarly, Mackay noted that the conical stones called lingas might equally have been gamesmen used in board games. These uncertainties show how cautious archaeologists must be in interpreting belief from material remains.

Exam Tips & Common Mistakes
How to score full marks in this chapter
Learn the dates of the three Harappan phases and the key sites with what each is famous for (Mohenjodaro – Great Bath and planning; Harappa – first discovered; Chanhudaro – crafts; Lothal – dockyard and drains; Dholavira – reservoirs and signboard; Rakhigarhi – biggest site and DNA study). For 8-mark essays, structure your answer with clear sub-headings (layout, bricks, drainage, houses, Citadel structures). Always support points with evidence (terracotta plough models, ploughed field at Kalibangan, nickel in copper, hoards of gold). Quote the historiography — Cunningham, Sahni, Banerji, Marshall, Wheeler, Dales — to show you understand how the past is reconstructed and re-interpreted.
Common mistakes to avoid
Confusing the Citadel (smaller, higher, western) with the Lower Town (larger, lower, eastern).
Writing that the script has been deciphered — it remains undeciphered.
Stating the Great Bath’s use as a fact — scholars only suggest it was a ritual bath.
Saying gold jewellery was found in burials — in fact all gold came from hoards; the Harappans rarely buried precious things with the dead.
Treating the “massacre” at Mohenjodaro as proven — Dales showed it was a myth.
Mixing up binary weights (1, 2, 4, 8…) with the decimal higher denominations (160, 200, 320, 640).
Frequently Asked Questions
What is Chapter 1 of Class 12 History about?
Chapter 1, Bricks, Beads and Bones, is about the Harappan (Indus Valley) Civilisation. It explains how archaeologists reconstruct Harappan life from material remains — subsistence, the planned city of Mohenjodaro, social differences, crafts, trade, seals, script and weights, authority, the end of the civilisation, and how it was discovered and interpreted.
Why do we depend on archaeology rather than writing to study the Harappans?
Because the Harappan script, though found on seals, tablets, jars and other objects, remains undeciphered. It is not alphabetical, has 375–400 signs and most inscriptions are very short. So historians rely on material evidence — houses, pottery, ornaments, tools, seals and bones — to reconstruct the civilisation.
Who discovered the Harappan civilisation?
Daya Ram Sahni found seals at Harappa and Rakhal Das Banerji found similar seals at Mohenjodaro in the early twentieth century. Based on these finds, John Marshall, Director-General of the ASI, formally announced the discovery of the Indus civilisation to the world in 1924, showing it was contemporaneous with Mesopotamia.
