For over a week the Gomti has submerged parts of Lucknow, the capital of Uttar Pradesh, affecting about 5,000 families, nearly 25,000 people (The Indian Express, 9 October 2026). The cause lay about 100 km upstream: around 150 mm of rain, against a normal 15 mm, fell between 22 and 27 September in the upper catchment (Pilibhit, Shahjahanpur, Lakhimpur Kheri, Sitapur). The flood wave reached Lucknow and the river rose suddenly on 7 October. The Lucknow Development Authority says riverfront flooding on this scale was last seen in 1982, and it has sent the State a project report for an embankment. The Opposition alleges that building was allowed on wetlands and floodplains, the flat land a river spreads over in high flow. The same day, the Agriculture card reports a monsoon deficit of 13% and warnings that drought in Maharashtra and Karnataka threatens the rabi chana (gram) crop.
Why open a history class with a flood? Because the first cities of the Indian subcontinent were built by people who lived with exactly these two forces: rivers that flood and monsoons that fail. The Harappans laid out streets in a grid, raised whole towns on brick platforms, ran covered drains along their streets, stored rain in stone reservoirs at Dholavira, and ploughed a field at Kalibangan in criss-cross furrows of the kind farmers in that region still use when they grow mustard and gram together. Yet floods also damaged their towns more than once (Lothal's excavator recorded a flood around 1900 BCE that ruined the township), and a drying climate is one of the leading explanations of their decline. So the honest lesson is not "our ancestors had solved floods"; it is that the oldest Indian cities survived for centuries by respecting water, and suffered when water changed course. That is today's concept: the Indus Valley (Harappan) Civilisation.

URGENT · FOR DECISION
To: Secretary, Housing & Urban Planning (also holding Culture), a State government
Subject: Rebuilding after the river flood: an embankment, a mound, a slogan and a village
The river has just flooded the riverfront of the State capital, the worst in four decades. The Chief Minister wants one note before Monday's Cabinet. Four papers are on your table.
(1) The city's development authority proposes an earthen embankment and, behind it, a new housing colony on "reclaimed" floodplain land. Its alignment passes within 200 metres of a mound that the Archaeological Survey of India (ASI) protects as an archaeological site of the Harappan period. The authority asks for permission to "start work now and regularise later".
(2) A Minister wants to announce a "Harappan-model drainage mission" for the capital: "Our ancestors had covered drains 4,500 years ago; we will copy them." The city engineer writes back that the real problem is that the drains cannot empty into a river that is higher than the drains.
(3) The flood has washed away soil on the mound's slopes. Children have picked up beads and pieces of painted pottery; a few are being sold to visitors. Farmers have ploughed the mound's lower edge for years and ask to sow gram and mustard there this rabi, because the monsoon has failed in their own fields.
(4) The Tourism Department proposes a concrete "replica Great Bath" and food court on the mound itself, to "bring the civilisation alive".
The Secretary wants one page: what the State will do now, what it will not do, what it must ask of the Union and the ASI, and what the city can genuinely learn from the past. You have 24 hours.

2The story
3The skeleton: sites, cities and the law that guards them
3a. What, when and where
The Harappan civilisation is named, by archaeological convention, after Harappa (on an old course of the Ravi, now in Pakistani Punjab), the first of its sites to be excavated. It was a Bronze Age culture: copper and bronze tools, no iron.
• Early Harappan: c. 3300–2600 BCE: farming villages and small towns (Kalibangan's ploughed field belongs here).
• Mature (urban) Harappan: c. 2600–1900 BCE: planned cities, standard bricks and weights, seals and the script, long-distance trade.
• Late Harappan: c. 1900–1300 BCE: cities shrink, the script and seals fade, settlement shifts east and south into smaller villages.
Extent: larger than ancient Egypt and Mesopotamia put together. Over a thousand Mature Harappan sites are reported, of which only about a hundred have been excavated. Commonly cited limits: Manda (Jammu, on the Chenab) in the north, Daimabad (Maharashtra) in the south, Alamgirpur (Meerut district, Uttar Pradesh) in the east and Sutkagen Dor (Makran coast, Balochistan) in the west, with a trading outpost at Shortugai in northern Afghanistan.
Rule of thumb: "Indus Valley" names a region, "Harappan" names a culture. Many of its sites, including Kalibangan and Rakhigarhi, lie not on the Indus but on the Ghaggar–Hakra river system.

Rule of thumb: "Indus Valley" names a region, "Harappan" names a culture. Many of its sites, including Kalibangan and Rakhigarhi, lie not on the Indus but on the Ghaggar–Hakra river system.
3b. The sites a topper can place on a map
| Site (today) | What it is known for |
|---|---|
| Harappa (Punjab, Pakistan) | First site excavated (from 1921, Daya Ram Sahni). Rows of brick buildings once called "granaries", working floors, cemeteries. Its bricks were dug out as ballast by engineers building the Lahore–Multan railway in the 1850s, an early lesson in heritage loss. |
| Mohenjo-daro (Sindh, Pakistan) | Excavated from 1922 (R. D. Banerji). The Great Bath (about 12 m × 7 m, 2.4 m deep, made watertight with bitumen), a raised citadel and a lower town in a grid, covered street drains and hundreds of wells; the bronze "Dancing Girl", the stone "Priest-King" and the "Pashupati" seal. World Heritage Site since 1980. |
| Kalibangan (Hanumangarh, Rajasthan) | On the Ghaggar. Excavated by the ASI in nine seasons (1960–61 to 1969–70) led by B. B. Lal, with B. K. Thapar in the team. A ploughed field of the Early Harappan phase (c. 2800 BCE in Lal's dating) with criss-cross furrows; rows of fire altars; evidence the excavators read as an ancient earthquake. The name means "black bangles", from the bangle pieces on the mound. |
| Lothal (Ahmedabad district, Gujarat) | Found in 1954, excavated 1955–60 (S. R. Rao). A brick basin the excavator called a dockyard; a bead-making workshop; a planned town damaged by floods more than once. A National Maritime Heritage Complex is being built nearby. |
| Dholavira (Khadir island, Kutch, Gujarat) | Discovered by J. P. Joshi of the ASI (1967–68); excavated by the ASI over 13 field seasons, 1989–2005, under R. S. Bisht. Built of stone; a castle (citadel) with a bailey and ceremonial ground, a middle town and a lower town; a chain of reservoirs fed by two seasonal streams; a "signboard" of ten large Indus signs. Inscribed as "Dholavira: a Harappan City" on the World Heritage List on 27 July 2021, the first Harappan site in India on the list. |
| Rakhigarhi (Hisar, Haryana) | On the Ghaggar plain; among the largest Harappan sites. A 2019 study of ancient DNA from one individual buried there found no steppe ancestry. Named among five "iconic archaeological sites" to be developed (February 2020). |
| Others to know | Chanhudaro (Sindh; bead-making, no citadel), Banawali and Bhirrana (Haryana), Surkotada (Kutch), Ropar (Punjab), Sanauli and Alamgirpur (western Uttar Pradesh). |
3c. How a Harappan city worked
| Feature | What the evidence shows |
|---|---|
| Planning | Many cities had a raised, walled citadel on the west and a larger lower town to the east, with streets meeting at right angles. Houses faced side lanes; many had a bathing area and a well. Dholavira's three-part plan shows there was no single template. |
| Bricks and platforms | Bricks of a standard ratio of about 1:2:4 (height : width : length) across distant sites. At Mohenjo-daro whole areas stand on massive brick and mud platforms that raised them above the plain, which many scholars read partly as protection against floods. |
| Drains | House drains emptied into covered street drains of brick; some large drains were big enough for workers to enter and clear blockages. These drains make the Harappan cities among the earliest known urban sanitation systems. Drains were built before houses: a sign of planning by some authority. |
| Water | Mohenjo-daro relied on hundreds of brick wells; Dholavira, in a dry land, dammed seasonal streams and stored water in a series of rock-cut and stone reservoirs. |
| Farming | Wheat, barley, pulses, sesame, cotton; rice at some Gujarat sites (Lothal, Rangpur). The ploughed field at Kalibangan and terracotta model ploughs (from sites such as Banawali) show the plough was in use. Cattle, sheep and goats were kept. |
| Crafts and standards | Beads of carnelian and other stones, shell bangles, copper and bronze, pottery painted red and black. Weights of cubical chert: on the standard reading (NCERT), the smaller ones in a binary series (1, 2, 4, 8, 16, 32), larger ones decimal. |
| Trade | Harappan seals and beads have been found in Mesopotamia; Mesopotamian texts speak of a land called Meluhha, generally identified with the Harappan region. Lothal and coastal sites link to the Gulf. |
| Script and seals | Square seals with an animal (often a "unicorn") and a short line of signs. The script, with a few hundred signs and very short texts, is undeciphered; it is generally thought to have been written right to left. |
| Beliefs | No temple or palace has been identified with certainty. Terracotta female figurines, the seated figure on the "Pashupati" seal, fire altars at Kalibangan and Lothal, and the Great Bath have led to interpretations of ritual and worship, all of them debated. |
3d. The constitutional and legal frame for a Harappan mound today
| Provision or body | What it does for this concept |
|---|---|
| Article 49 (Directive Principle) | The State shall protect every monument, place or object of artistic or historic interest declared by Parliament to be of national importance from spoliation, disfigurement, destruction, removal, disposal or export. |
| Article 51A(f) (Fundamental Duty) | Every citizen shall value and preserve the rich heritage of our composite culture. |
| Seventh Schedule | Union List Entry 67: ancient and historical monuments, archaeological sites and remains declared by Parliament to be of national importance. State List Entry 12: other ancient monuments (and libraries, museums). Concurrent List Entry 40: archaeological sites and remains other than those of national importance. |
| Ancient Monuments and Archaeological Sites and Remains (AMASR) Act, 1958 | Lets the Union declare sites to be of national importance and protect them through the ASI; an "ancient monument" is one that has existed for at least 100 years. The 2010 amendment made the area within 100 m of a protected monument prohibited for new construction and a further 200 m regulated (permission needed), and created the National Monuments Authority, which approves the heritage bye-laws prepared for each protected site. |
| Antiquities and Art Treasures Act, 1972 | Regulates the export of and trade in antiquities and requires registration of certain antiquities. |
| Indian Treasure Trove Act, 1878 | Anyone who finds "treasure" (anything of value hidden in the soil) worth more than ten rupees must give written notice to the Collector; failure is punishable. The district officer is the law's first door for a chance find. |
| World Heritage Convention, 1972 (UNESCO) | States list sites of "outstanding universal value" and accept duties of protection and management. India ratified it in 1977. Dholavira is listed under criteria (iii) and (iv). |
Rule of thumb: the Constitution says protect; the AMASR Act says how far (100 m, then 200 m more); the Treasure Trove Act says who must be told (the Collector).
4The fine print — what separates a topper from the rest
1. "Indus Valley" is a misnomer; "Harappan" is a convention. A large share of known sites lie on the Ghaggar–Hakra system in Haryana, Rajasthan and Cholistan, and in Gujarat. Naming a culture after its first-excavated site is standard archaeological practice, not a claim that Harappa was the capital. There is no evidence of a single capital or a single king.
2. Planned does not mean identical. The citadel-on-the-west, lower-town-on-the-east pattern fits Harappa, Mohenjo-daro and Kalibangan, but Dholavira has three parts, Lothal's plan differs, and Chanhudaro has no citadel. In an answer, write "many Harappan cities", never "all".
3. Two famous labels are contested. Mortimer Wheeler called a large building at Mohenjo-daro the "Great Granary"; later scholars found no grain there and prefer "Great Hall". S. R. Rao's "dockyard" at Lothal has been read by others as a reservoir or tank. Examiners like statements that turn a debated label into a fact.
4. Kalibangan's field is older than the city. The criss-cross furrowed field, found outside the town wall, belongs to the Early Harappan phase (c. 2800 BCE in its excavator's dating), and is often called the earliest ploughed field found by excavation. The furrows run close in one direction and wide in the other, the pattern still used in the region when two crops such as mustard and gram are sown together: an early form of risk-spreading in a dry land.
5. Bronze, not iron; the horse is not settled. The Harappans used copper, bronze, stone and shell; iron is absent. Firm evidence of the domesticated horse is lacking, and claims from a few sites are disputed. Do not mark "the Harappans used iron ploughs" or "the horse was central to Harappan life" as true.
6. The script is undeciphered, and that limits every claim. Inscriptions are very short (a handful of signs), with no long bilingual text. So we do not know the Harappans' language, the names of their rulers or what the seals say. Everything about their religion and politics is inference from objects. Be wary of any statement that "the script has been deciphered".
7. The decline had many causes, not one villain. Wheeler's view that invaders destroyed Mohenjo-daro rested on a few skeletons from different levels; George Dales and others showed there is no destruction level at the end of the city, and the theory is now generally rejected. Leading explanations combine a weakening monsoon and drier climate from the late third millennium BCE, shifting or drying rivers (especially the Ghaggar–Hakra), floods at some sites, and a fall in long-distance trade. The cities faded; the villages and many ways of life continued.
8. DNA adds evidence but does not end debate. The 2019 study (in the journal Cell) of one individual from Rakhigarhi found a mixture of ancestry related to ancient Iranians (the largest part, from a lineage older than Iran's first farmers) and ancestry related to South-east Asian hunter-gatherers, and no steppe-pastoralist ancestry. It is one genome, so the honest reading is careful: it tells us about the people of that time, while questions about later migrations and the languages of the Vedic age continue to be studied.
5How the idea grew
1820s → 1875The traveller Charles Masson describes the ruins at Harappa (published 1842). Alexander Cunningham, later the first head of the ASI (founded 1861), visits Harappa in 1853 and publishes a seal in 1875 without knowing its age. Railway builders carry away Harappa's bricks in the 1850s.
1904The Ancient Monuments Preservation Act gives the colonial government power to protect sites.
1921 → 1924Daya Ram Sahni excavates at Harappa (1921) and R. D. Banerji at Mohenjo-daro (1922). In September 1924 ASI Director-General John Marshall announces a new, forgotten civilisation to the world.
1944 → 1947Mortimer Wheeler heads the ASI and excavates at Harappa, exposing its fortifications. Partition places Harappa and Mohenjo-daro in Pakistan; Indian archaeologists begin a search that uncovers many more sites in Gujarat, Rajasthan, Haryana and Punjab.
1954 → 1960Lothal is found (1954) and excavated (1955–60).
1958The AMASR Act replaces the 1904 law for sites of national importance.
1960 → 1970The ASI excavates Kalibangan; the ploughed field and fire altars come to light.
1967 → 2005Dholavira is identified (1967–68) and excavated (1989–2005), revealing its reservoirs and signboard.
1972 → 1980The Antiquities and Art Treasures Act (1972) and UNESCO's World Heritage Convention (1972; India ratifies 1977); Mohenjo-daro becomes a World Heritage Site (1980).
2010The AMASR (Amendment and Validation) Act creates prohibited and regulated zones around protected monuments and the National Monuments Authority.
2019 → 2021The Rakhigarhi ancient-DNA study is published (2019); Rakhigarhi and Dholavira are among five sites named for development as "iconic sites" (2020); Dholavira is inscribed on the World Heritage List (27 July 2021).
October 2026The Gomti floods Lucknow's riverfront on a scale last seen in 1982; the debate turns to floodplains, drains and embankments, the oldest urban questions in India.
6One issue, six lenses
Polity & law
Heritage is protected by Article 49, Article 51A(f), three entries of the Seventh Schedule, the AMASR Act's 100 m and 200 m zones and the Collector's role under the Treasure Trove Act. "Start now, regularise later" has no place near a protected site.Carry: the past has a legal address; know which office holds the key.
Social justice
Harappan cities show differences in house sizes and burials, so inequality is old. Today, those who live on floodplains and on the edges of mounds are mostly the poor, and they bear the first loss from both floods and fencing.Carry: protect the site and the floodplain without making the poorest pay for both.
Governance
Standard bricks, standard weights, drains laid before houses, and drains built to be cleaned: Harappan cities point to rules that were made and maintained, by whatever authority. Modern cities fail less for lack of drains than for lack of upkeep and of planning that leaves room for water.Carry: a city is governed well when its standards are kept, not merely announced.
Economy
Craft specialisation, standard weights and trade reaching Mesopotamia made an early market economy. Today, sites like Dholavira and Lothal can bring tourism and livelihoods, if heritage is not concreted over for a quick footfall.Carry: heritage pays for a long time only if it is not spent at once.
Ethics
Honesty about the past: neither "our ancestors solved everything" nor dismissing a civilisation because its script is unread. Stewardship: the mound belongs to those not yet born. A slogan that bends evidence harms both history and policy.Carry: say what the evidence says, no more and no less.
Citizen & nation
The Harappans were among the world's first city builders, and many threads of daily life on the subcontinent (crops, crafts, ways of building and farming) have deep roots there. Pride grows from knowing this accurately and guarding it in practice.Carry: a nation honours its oldest cities by learning from them and protecting them, not by copying their slogans.
7From paper to village — the implementation chain
1
The chance find: a farmer's plough, a flood or a builder's trench exposes pottery, beads or bricks. The finder must tell the Collector (Treasure Trove Act). Breaks if: no one in the village knows the law, or fears the land will be taken, so objects are sold quietly.
2
Survey: the ASI circle or the State archaeology department records the site, its extent and its period. Breaks if: the survey is never done, or the site's boundary on paper is smaller than the mound on the ground.
3
Notification: the Union declares the site to be of national importance under the AMASR Act (or the State protects it under its own law). Breaks if: land records are not corrected, and owners learn of the protection only when a permit is refused.
4
Zoning: 100 m prohibited, a further 200 m regulated; site-wise heritage bye-laws are prepared and approved by the National Monuments Authority; the city's master plan must show these zones (and the river's floodplain). Breaks if: the development authority's plan and the heritage map do not talk to each other.
5
Excavation and conservation: licensed, scientific digging, publication of reports, conservation of exposed walls, a site museum. Breaks if: trenches are left open to rain and floods, or reports are not published for decades.
6
District: the Collector, police and ASI staff prevent encroachment and illegal digging; the disaster plan includes the site. Breaks if: one watchman guards many hectares.
7
The village: guides, artisans, homestays, school visits; farmers given fair alternatives for land they lose. Breaks if: villagers see the site only as a fence, and not as something that is theirs to be proud of and earn from.
8Who wants what
| Stakeholder | Wants | Fears | Their fair point |
|---|---|---|---|
| Flood-hit residents | Safety now, and protection before the next monsoon | Being told to move with nowhere to go | Many bought or built with permission the State itself gave. |
| Development authority and builders | Land for housing and a quick embankment | Delay, cost overruns, a project stuck in clearances | A growing capital needs homes, and a dense city cannot simply be moved. |
| ASI and archaeologists | An untouched mound and its surroundings, time for proper study | Bulldozers, looting and flood damage destroying evidence that can never be recovered | A site, once dug or built over, is lost for ever; a road can be realigned. |
| Farmers near the mound | To keep sowing the land, especially in a drought year | Losing land and income to a fence | They have farmed there for generations, often before the protection was notified. |
| Tourism Department and local traders | Visitors, events, revenue | A neglected site that no one visits | Without visitors and income, protection has no local supporters. |
| Students and teachers | A place where history is seen, not only read | Replicas and slogans in place of real evidence | The best guard for heritage is a citizen who understands it. |
9The human side — EQ, citizen first, nation first
The people behind the file. A retired clerk in a riverside colony has carried his furniture to the roof for the third day; he bought the plot with an approved map and does not understand why his home is now called "floodplain". A young mother in the village by the mound has sold three beads her son found, for less than the price of a school bag, not knowing they were evidence and not knowing the law. An old farmer has sown gram on the mound's edge every winter since he was a boy, and this year his own field is too dry.
An officer with emotional intelligence does not begin with a penalty. She meets the residents and tells them plainly what the State will do before the next monsoon. She goes to the village with the ASI's officer and a teacher, holds one of the beads in her palm, and explains to the mother that this tiny stone was drilled by a craftsperson more than four thousand years ago, that her son has found something the whole country should see, and that the State will record his name in the site museum when he hands it in. She asks the farmer to help the ASI mark the mound's true edge, and finds him land and drought relief elsewhere.
Citizen first: safety of flood-hit families, fair treatment of farmers, and no punishment for ignorance where a little explanation will do. Nation first: the mound is a page of the country's oldest urban history, not the property of one project or one season; it must not be lost to a road, a replica or a quick sale.

10The concept web — where this sits in your mind
Vedic Age — what came after the cities faded; the continuity and migration debates; the shift from city to village and from seal to oral text (histsoc-002). Darpan Lens: continuity and change.
Harappan art — seals, the bronze "Dancing Girl", the stone "Priest-King", terracotta figurines, painted pottery and beads (histsoc-061; GS1 Indian culture).
Urban floods — floodplains, drains that cannot empty into a high river, embankments that move risk; today's Gomti card (geoenv-046; GS3 disaster management).
Monsoon & drought — monsoon variability then and now; a drying climate in the Harappan decline; El Niño and the 13% deficit today (geoenv-024, geoenv-049).
World Heritage — Mohenjo-daro (1980), Dholavira (2021), the 1972 Convention and India's listed sites (histsoc-078). Darpan Lens: global.
Cropping patterns — Kalibangan's furrows for two crops; mixed cropping as insurance; rabi gram and mustard in dry lands (geoenv-032, geoenv-027).
Urbanisation — the first planned cities and today's unplanned growth; master plans, zoning, upkeep (histsoc-096, geoenv-038; polity-084 for urban local bodies).
Water & irrigation — Dholavira's reservoirs and traditional water harvesting; water-use efficiency today (geoenv-035, economy-077).
On the website, each of these opens its own class as the library grows. Each new class adds lines to this web.
11Your decision — back to the file
You are the Secretary. Choose the line you will send to the Chief Minister:
The note an officer would write
1. Two forces meet on this file: a river that has reclaimed its floodplain, and a protected archaeological site of the Harappan period. Both are permanent; our plan must fit around them.
2. Flood relief: relief and temporary shelter for affected families to continue; a protection plan for existing dense colonies before the next monsoon, with pumps and sluices at drain outfalls.
3. Embankment: to proceed only after a hydrological study of upstream and downstream effects. Alignment to avoid the 100-metre prohibited area of the protected mound; any part within the further 200-metre regulated area to need prior permission through the National Monuments Authority. No "regularise later".
4. Floodplain: the active floodplain to be mapped and notified; no new colony on it. The proposed colony to be reconsidered on safer land.
5. Drainage: the city's problem is outfalls into a high river and choked drains, not the absence of drains. A plan for outfalls, desilting before the monsoon and covered, cleanable drains to be prepared. Harappan cities may be cited as an example of planning and upkeep, not as a design to copy.
6. The mound: with the ASI, its edge to be marked on the ground and in land records. Finds to be handed to the Collector under the Treasure Trove Act; a one-month amnesty, with finders credited in the site museum. Farmers on the mound's edge to be offered alternative land or support, with priority in drought relief.
7. Tourism: no concrete structure on the mound. A small site museum, signage and trained local guides instead.
8. Request to the Union: ASI survey and conservation of the flood-damaged slopes; early approval by the NMA of heritage bye-laws for the site.
9. Submitted for approval.

| Essay | "The river remembers its floodplain"; "Civilisations are built on water and broken by it"; "What we inherit, we must also maintain." |
| Interview | "You are posted as Collector of Kutch. Dholavira draws more tourists every year. How will you balance visitors, the village and the site?" |
Trap: "All Harappan cities were divided into a citadel and a lower town." — False; Dholavira had three divisions, and Chanhudaro had no citadel.
Trap: "The Harappans used iron tools and ploughs." — False; it was a Bronze Age culture. Iron is absent.
Trap: "The Indus script was deciphered with the help of a bilingual inscription." — False; no such inscription has been found, and the script remains undeciphered.
Trap: "Most Harappan sites lie on the Indus and its tributaries in Pakistan." — Not safe; a large share of known sites lie in India, many on the Ghaggar–Hakra system and in Gujarat.
Mains practice 1 (GS1)
"The town planning of the Harappan cities reflects a concern for water that modern Indian cities would do well to recover." Critically examine. (15 marks, 250 words)Model approach
Directive — Critically examine: test the claim, show its limits, then conclude. Introduction: the Mature Harappan cities (c. 2600–1900 BCE) were planned on a grid with standard bricks. Evidence for: covered street drains, the larger ones big enough to be cleared; raised platforms at Mohenjo-daro; wells; Dholavira's reservoirs fed by seasonal streams. Limits: floods still damaged Lothal and other towns; a drying climate and shifting rivers contributed to decline; we do not know who governed or how; ancient cities held tens of thousands, not millions. Today's example: the Gomti flood in Lucknow (October 2026), where rain 100 km upstream met building on the floodplain. Conclusion: the lesson is not a design but a principle: leave room for water, plan before you build, and maintain what you build.Mains practice 2 (GS1)
"What do the excavations at Kalibangan, Lothal and Dholavira reveal about the economy of the Harappan civilisation?" (10 marks, 150 words)Model approach
Directive — reveal: use site evidence. Kalibangan: ploughed field with criss-cross furrows (Early Harappan), pointing to plough agriculture and possibly two crops sown together. Lothal: bead-making workshop and a basin read as a dockyard, pointing to craft production and sea trade (with the debate noted). Dholavira: reservoirs and water management in a dry land; stone architecture; the signboard as evidence of public writing. Wider: standard weights, seals found in Mesopotamia ("Meluhha"). Conclusion: a mixed economy of farming, specialised crafts and long-distance trade, held together by shared standards.13Check yourself
1. Give the approximate dates of the Early, Mature and Late Harappan phases.
Answer
Early c. 3300–2600 BCE; Mature (urban) c. 2600–1900 BCE; Late c. 1900–1300 BCE.2. Why is "Harappan" often preferred to "Indus Valley", and on which river system lie Kalibangan and Rakhigarhi?
Answer
Archaeologists name a culture after its first-excavated site, and many sites lie outside the Indus valley proper. Kalibangan and Rakhigarhi lie on the Ghaggar–Hakra system.3. What was found at Kalibangan, and why does it matter for today's farmer?
Answer
An Early Harappan ploughed field (c. 2800 BCE in its excavator's dating) with criss-cross furrows, plus fire altars. The furrow pattern matches the way farmers in that region still sow two crops such as mustard and gram together, spreading risk in a dry land.4. Name three features of Dholavira that make it distinctive.
Answer
A three-part plan (castle with bailey, middle town, lower town); a system of reservoirs fed by two seasonal streams; a "signboard" of ten large Indus signs. It is built largely of stone and was inscribed as a World Heritage Site in 2021.5. How did Harappan drains work, and what is the honest lesson for a flooded modern city?
Answer
House drains fed covered brick street drains, the larger ones big enough for workers to enter and clear. The lesson is planning and upkeep, and leaving room for water; Harappan towns too were damaged by floods.6. Name two Harappan "labels" that scholars dispute.
Answer
The "Great Granary" at Mohenjo-daro (now often called the "Great Hall") and the "dockyard" at Lothal (read by some as a reservoir or tank).7. List the main explanations for the decline of the Harappan cities.
Answer
A weakening monsoon and drier climate, shifting or drying rivers (especially the Ghaggar–Hakra), floods at some sites, and a fall in long-distance trade. Wheeler's invasion theory is generally rejected.8. Under which laws would a Collector act if villagers find beads on a protected Harappan mound?
Answer
The Indian Treasure Trove Act, 1878 (finds worth more than ten rupees must be reported to the Collector); the AMASR Act, 1958 (protected site, 100 m prohibited and a further 200 m regulated area); and the Antiquities and Art Treasures Act, 1972 (trade and export of antiquities). Article 49 and Article 51A(f) give the constitutional basis.“Know it, link it, feel it, decide it.”
