Indus Valley Civilization (IVC): Background and Origin
Key Point
The Indus Valley Civilization (IVC) , also called the Harappan Civilization , was one of the world’s earliest urban civilizations (c. 2500–1750 BCE). It is categorized as a Proto-Historic and Bronze Age culture, flourishing in the northwestern regions of the Indian subcontinent, known for its advanced city planning, trade, and craft specialization.

Background (The Basics — for beginners)
The IVC is a Bronze Age civilization because people used bronze (copper + tin) tools; bronze is stronger than pure copper, so tools lasted longer.
It is Proto-History : they had a script on seals, but it is undeciphered , so we rely mainly on archaeology (not readable texts).
It flourished along the Indus and its tributaries across today’s Pakistan and western India (Punjab, Sindh, Gujarat, Haryana, Rajasthan).
First major sites: Harappa (1921, Daya Ram Sahni) and Mohenjo-daro (1922, R.D. Banerjee) .
Famous for urban planning , standardized weights , seals , and advanced drainage .
Origin (How it Grew — simple view)
Not sudden: it evolved from local Neolithic–Chalcolithic farming cultures (steady growth in village size, storage, craft).
Early Harappan (3300–2600 BCE): move from villages to towns; grain storage increases; more trade; potters and bead-makers specialize. Mehrgarh is an early farming precursor.
Mature Harappan (2600–1900 BCE): peak urban phase with planned cities , standard bricks , writing on seals, long-distance trade.
Late Harappan (1900–1500 BCE): de-urbanization and a return to smaller, rural settlements.
Most accepted view: largely indigenous rise built on local farming, with external trade links (e.g., Mesopotamia) helping growth.
Phases of Indus Valley Civilization
| Phase | Time Period | Key Features |
|---|---|---|
| Early Harappan | 3300–2600 BCE | Village → town transition; storage and trade begin |
| Mature Harappan | 2600–1900 BCE | Planned cities , Bronze , seals , long-distance trade |
| Late Harappan | 1900–1500 BCE | De-urbanization , rural shift, cultural thinning |
Fun Facts
Harappans cultivated cotton early; Greeks later called it ‘ Sindon ’.
Great Bath at Mohenjo-daro is among the earliest public water tanks.
No huge palaces/temples: religion and power looked different from Egypt/Mesopotamia.
Standard weights suggest tightly managed trade and administration.
Mains Key Points
IVC is the subcontinent’s first urbanization with planned towns.
Origin is largely indigenous (Mehrgarh line), with external trade aiding growth.
Economy blends agriculture , craft specialization , and long-distance trade .
Decline later shows how environment + economy shape civilizations.

Major Sites and Features (Crucial for Prelims)
Harappa (Punjab, Pakistan)
First site discovered (1921) — this is why the whole culture is also called “Harappan”.
Key finds: Granaries (big storage buildings for grain) outside the citadel, Cemetery R-37 (burials showing how people were laid to rest), and many seals used for trade/identity.
Beginner tip: Think “H” for Harappa and Huge grain storage.
Mohenjo-daro (Sindh, Pakistan)
Among the largest site of the IVC (often paired with Rakhigarhi).
Key structures: the Great Bath (a large tank for ritual/public bathing), a massive Granary , and an Assembly Hall (gathering space).
Key finds: the Bronze Dancing Girl (lost-wax casting, shows metal skill) and the Bearded Priest statue (elite/ritual imagery).
Beginner tip: “M” for Mohenjo-daro and Massive Bath .
Lothal (Gujarat, India)
A major Port City (coastal) — think boats and overseas trade.
Unique find: an artificial Dockyard (rectangular basin linked to sea channels) — strong proof of maritime trade.
Also known for Rice remains (rare in IVC), bead-making workshops (agate/carnelian), and fire altars (ritual spots).
Beginner tip: “Lo-‘thal’” → like “ lo ading at the thal (dock)”.
Kalibangan (Rajasthan, India)
Name means ‘ Black Bangles ’.
Unique find: clearly marked ploughed fields (furrow marks) — direct evidence of farming technique; multiple fire altars (ritual).
Beginner tip: “Kali- bang an” → bang les + ploughed fields.
Dholavira (Gujarat, India)
Urban layout is special: divided into three parts — Citadel (upper), Middle Town, and Lower Town (most IVC towns have two parts).
Key finds: very large Water Reservoirs (advanced water harvesting) and a long Harappan inscription on a signboard (rare, shows public display of signs).
Beginner tip: “Dho-la- water ” → remember water management and three -part town.
Rakhigarhi (Haryana, India)
Currently the Largest Harappan site in India (area-wise).
Evidence: wide streets, house layouts, granaries , and burials — shows a major urban center in the Saraswati-Ghaggar belt.
Beginner tip: Rakhi -garhi → tie the “largest in India” fact to your memory like a rakhi.
Mehrgarh (Baluchistan, Pakistan)
A Pre-Harappan Neolithic–Chalcolithic site (c. 7000 BCE).
Earliest agriculture and domestication in the region; pottery, storage, and village life evolved here — seen as a cultural foundation for IVC’s later urban rise.
Beginner tip: “Mehr” (more/early) → more early farming .
Major Indus Valley Sites and Key Features
| Site | Region | Unique Features |
|---|---|---|
| Harappa | Punjab (Pakistan) | Granaries , seals, Cemetery R-37 |
| Mohenjo-daro | Sindh (Pakistan) | Great Bath , Dancing Girl , Bearded Priest |
| Lothal | Gujarat (India) | Dockyard , rice remains, bead-making |
| Kalibangan | Rajasthan (India) | Ploughed fields , Fire Altars |
| Dholavira | Gujarat (India) | Water reservoirs , Three-part division |
| Rakhigarhi | Haryana (India) | Largest Harappan site in India , burials |
| Surkotada | Gujarat (India) | Horse bones , fortified settlement |
| Ropar | Punjab (India) | Burial with dog and human skeletons |
| Chanhudaro | Sindh (Pakistan) | Bead-making, No Citadel (only lower town) |
| Mehrgarh | Baluchistan (Pakistan) | Precursor to Harappan culture (Early Farming) |
Prelims Strategy Tips
Harappa – Granaries and Cemetery R-37 = storage + burial evidence.
Mohenjo-daro – Great Bath + Dancing Girl = public works + metal art.
Lothal – Dockyard proves sea trade; remember rice remains.
Kalibangan – Ploughed fields and fire altars = farming + ritual.
Dholavira – Reservoirs + three-part city = unique planning.
Rakhigarhi – largest site in India; tie this fact like a ‘rakhi’.
Indus Valley Civilization: Civic and Political Features
Key Point
The IVC (2600–1900 BCE) was remarkable for its advanced civic planning , highly efficient drainage , and fortified towns. Its political structure was unique: it showed no evidence of an individual king, palace, or centralized monarchy , suggesting a form of collective governance .

Town Planning (The Grid System)
Streets: Cities were laid out in a neat grid pattern . Main roads ran North–South and East–West and met at right angles , making navigation easy and traffic organized.
Division: Most cities had two zones — a higher Citadel (public buildings, storage, special activities) and a larger Lower Town (residential area for people).
Construction: Houses and public buildings used standardized burnt bricks (4:2:1 ratio). This meant parts were uniform, faster to build, and easier to maintain.
Houses: Usually had rooms around a central courtyard, private wells/bath areas, and doors opening to side lanes (privacy + cleanliness).
Drainage System (Civic Sense)
Civil engineering: One of the world’s earliest covered drainage systems. Drains made of baked bricks ran along streets and were covered with stone slabs or bricks.
House connection: Every house had a small drain leading to the street’s main drain. Soak-pits filtered out solids before wastewater entered main drains.
Maintenance: Inspection holes were provided at intervals for cleaning — proof of regular municipal care.
Why it matters: Shows awareness of hygiene , flood control, and urban planning far ahead of many contemporary cultures.
Fortification
Citadel platforms were raised and fortified with strong brick walls.
Uses: Likely for defense, flood protection, and to keep important buildings (granaries, halls, baths) safe.
Takeaway for exams: Fortified citadel ≠ royal palace; it’s a public/administrative zone.
Political Structure (A Puzzle)
Absence of kingship markers: No clear palaces , royal tombs , or large temples like in Egypt/Mesopotamia.
Yet high uniformity: Standardized weights , brick sizes, town plans, and seal use across far-apart cities suggest central regulation or a strong collective governance model.
Likely possibilities: Governance by merchant elites , city councils , or a civic-religious body (the so-called “Priest-King” figurine is suggestive but not proof).
Exam hint: Write “no clear monarchy; evidence favors regulated, committee-like control coordinating standards and public works.”
Civic and Political Features of IVC
| Feature | UPSC Significance |
|---|---|
| Street Planning | Grid Pattern , right-angle roads → planned, predictable, efficient city life |
| Drainage | Covered, baked brick drains , soak-pits, inspection holes → hygiene + maintenance |
| Fortification | Citadel platforms, walls → defense + flood control; public buildings located here |
| Political Structure | No monarchy evidence ; uniform standards → collective/merchant council style governance |
Prelims Strategy Tips
Use the phrase: “ Grid roads + covered drains + citadel = IVC standard.”
Standard bricks (4:2:1) are a signature of Harappan construction.
Citadel ≠ palace: think public/administrative zone .
Write “ No clear monarchy ; likely collective governance based on uniform standards and seals.”
Indus Valley Civilization: Art, Economy and Trade
Key Point
The IVC economy was robust, built on agricultural surplus , specialized crafts, and extensive trade networks . Their art was expressive, with notable achievements in terracotta , bronze casting , and sealing technology—clear signs of high technical skill.

Art and Craft (High Skill Level, Simple Words)
Terracotta Figurines (baked clay): Small clay figures of animals, toys, carts, and the Mother Goddess . Terracotta simply means clay objects fired in a kiln so they become hard.
Bronze Figurines: Made by the lost-wax casting method ( Cire Perdue ): first make a wax model → cover with clay → melt the wax → pour in molten metal. Famous example: 'Dancing Girl' of Mohenjo-daro (slim figure, confident pose, detailed bangles).
Stone Sculptures: Fewer in number but very refined; the Bearded Priest shows patterned robe and headband—suggesting elite or ritual roles.
Seals (for stamping): Over 4,000, mostly square, carved on steatite (soft stone; easy to carve, turns hard after firing). They show animal motifs (bull, elephant, unicorn ) plus short undeciphered script . The Pashupati seal (figure surrounded by animals) is the most famous.
Jewellery and Beads: Gold, silver and stones like carnelian and lapis lazuli . Cities like Lothal and Chanhudaro had specialised bead-making workshops—beads were drilled with very fine tools, showing precision.
Pottery: Mostly red/black painted designs (geometric, floral). Large storage jars and fine tableware show both utility and aesthetics.
Economy (How People Earned and Stored Wealth)
Agriculture was primary: Main crops: wheat , barley ; they were the first to cultivate cotton (later called ‘Sindon’ by Greeks). Rice remains occur at sites like Lothal and Rangpur (not everywhere).
Why surplus matters: Surplus grain (kept in granaries ) feeds non-farmers (craftspeople, traders, administrators). This is how cities and specialisations grow.
Handicrafts & Metallurgy: Advanced pottery , bead-making , and metal work in copper and bronze . Crafts were often done in dedicated areas (workshops), suggesting organised production.
Animals and Tools: Oxen pulled carts and ploughs; the humped bull icon hints at its value in farming and transport.
Trade and Commerce (How Goods Moved)
Standardized weights & measures: Weights often follow multiples of 16 (16, 32, 64...). Standardisation means fair deals across far-flung towns.
Internal trade: Bullock carts and boats moved goods along roads and rivers. Seals probably marked ownership or quality (like a brand logo + tag).
External trade: Sea and land links to Mesopotamia (Sumer), Oman , Bahrain , Iran , and Central Asia . Harappans likely exported cotton textiles, beads, carnelian, shell items; they imported metals (copper, tin), lapis lazuli , and other stones.
Archaeological clues: Harappan seals found in cities like Ur and Susa ; the dockyard at Lothal shows planned maritime trade.
Beginner Memory Aids
Art = 3 S’s: Seals (trade/admin), Sculptures (bronze & stone), Storage pottery (daily life).
Economy = 3 G’s: Grain (farming), Granaries (storage), Guild-like crafts (specialists).
Trade = 3 R’s: Roads , Rivers , Routes overseas (Lothal).
IVC Art, Economy and Trade
| Aspect | Key Features |
|---|---|
| Art | Dancing Girl (Bronze, lost-wax), Bearded Priest (Stone), Mother Goddess (Terracotta), Seals (steatite) |
| Economy | First to cultivate cotton ; wheat & barley; granaries ; specialised workshops |
| Trade | Standard weights (16-based); Harappan seals abroad ; Lothal dockyard = maritime links |
Prelims Strategy Tips
The 'Dancing Girl' is a bronze figurine from Mohenjo-daro made via lost-wax casting.
Harappans were the first to grow and export cotton from South Asia.
Lothal = bead-making hub + dockyard (maritime trade).
Harappan weights often follow a 16-based system (16, 32, 64...).
The Unicorn is the most frequent animal motif on seals.
Indus Valley Civilization: Religion and Beliefs
Key Point
Harappan religion, reconstructed purely from archaeological finds (seals, figurines, altars), was largely non-anthropomorphic (non-human-like god). The core beliefs centered on fertility, nature worship, and ancestor veneration, characterized by the Mother Goddess and the Pashupati (Proto-Shiva) figure.

Key Figures and Deities
Mother Goddess (Goddess of Fertility): Numerous terracotta figurines of pregnant women suggest the worship of a Mother Goddess, symbolizing fertility , the source of creation, and plant life. This was likely a primary form of worship for most common people.
Pashupati Mahadeva (Proto-Shiva): Found on a famous seal from Mohenjo-daro, a figure is seated cross-legged on a low throne, surrounded by animals (elephant, tiger, rhinoceros, buffalo). This figure is commonly identified as a Proto-Shiva (Lord of the Beasts).
Nature Worship
Tree Worship: The Pipal tree (Ficus religiosa) is frequently depicted on seals, suggesting its sanctity (worship continues in modern Hinduism).
Animal Worship: Animals like the Humped Bull (power, fertility) and the mythical Unicorn (the most common motif on seals) were revered, possibly as totems or divine vehicles.
Water Worship: The massive Great Bath at Mohenjo-daro suggests the ritual importance of water/bathing (purification) in public life.
Rituals and Practices
Fire Cult: Evidence of fire altars (e.g., at Kalibangan and Lothal ) suggests the performance of fire-based rituals, possibly related to fertility or purification.
Amulets: Found on many bodies, suggesting belief in magic or protection from evil spirits.
Burial Practices (Belief in Afterlife)
Harappans practiced both complete burial (laying the body out) and fractional burial (burial of bones after exposure).
Graves often contained pottery , ornaments , and tools (grave goods), clearly indicating a belief in life after death (ancestor veneration).
Harappan Religious Beliefs (Summary)
| Belief Element | Archaeological Evidence | Connection to Modern India |
|---|---|---|
| Fertility God | Pashupati Seal (Proto-Shiva), Yogic Pose | Shiva worship (Yogic posture, 'Lord of the Beasts') |
| Fertility Goddess | Numerous Mother Goddess Terracotta Figurines | Shakti/Devi worship tradition |
| Nature Worship | Pipal tree (sacred), Animal Motifs (Bull, Unicorn) | Tree and Animal worship (e.g., Peepal, Vahana) |
| Ritual Purity | Great Bath at Mohenjo-daro, bathing areas in houses | Ritual bathing (e.g., in Rivers) |
| Fire Rituals | Fire Altars at Kalibangan, Lothal | Vedic Havan/Yagna rituals (Agnihotra) |
| Afterlife | Grave goods (pots, tools) in burials | Ancestor veneration (Shraddha) |
Mains Key Points
Harappan religion was non-Vedic and lacked prominent temples, relying on nature, fertility, and ritual bathing.
The IVC provided the roots for later Hindu traditions , notably the Pashupati figure (Proto-Shiva) and the Mother Goddess worship (Shakti).
Absence of large temples suggests a non-centralized political structure or a civic-religious form of governance , unlike Egypt or Mesopotamia.
Prelims Strategy Tips
Pashupati Seal and Dancing Girl are from Mohenjo-daro .
Mother Goddess figurines are mostly terracotta (not bronze/stone).
Fire Altars are key finds at Kalibangan and Lothal .
The Unicorn is the most commonly depicted animal on Harappan seals.
Decline of the Indus Valley Civilization
Key Point
The decline of the IVC (c. 1900–1500 BCE) was a gradual process across regions—often called de-urbanization . It likely resulted from combined ecological , economic , and internal pressures, not a single invasion.

Nature and Evidence of Decline (What We Actually See)
Gradual & uneven: Big cities shrank first; people moved to smaller towns/villages.
Loss of standardisation: Weights , seal usage , and tight town planning become irregular in late layers.
Late Harappan cultures: Eg., Cemetery H (Punjab), Jhukar (Sindh), Rangpur (Gujarat) show continuity of some traditions but simpler life.
Major Causes (Easy to Remember: 3 E’s — Environment, Economy, (internal) Elasticity break)
1) Ecological & Climatic (Most accepted)
River shifts/drying: The Saraswati (Ghaggar-Hakra) system weakened; other rivers changed course → less reliable water for cities/farms.
Less rainfall: Drier climate → desertification in some zones → lower crop yields.
Flood cycles: Repeated floods (e.g., at Mohenjo-daro layers) also damaged settlements.
2) Economic & Social
Trade decline: Long-distance trade with Mesopotamia reduced after c. 1900 BCE → urban industries suffered.
Soil stress & population pressure: Overuse of land and growing cities may have lowered farm output per head.
Management limits: Without clear kingship, citywide crisis management may have been hard—standards and big projects slowed.
3) Invasion/Migration (older idea)
Earlier scholars proposed an Aryan invasion ; modern research finds no firm evidence for a sudden, large-scale military collapse. The change looks internal + environmental .
What Happened Next (Consequences)
From city to village: Crafts continued but at smaller scales; daily life became more local.
Cultural continuity: Some pottery styles, symbols, and farming practices carried into later cultures of the Gangetic plains.
Beginner Memory Aids
3 D’s: Drier climate + Damaged rivers + Declining trade.
De-urbanization = fewer big public works, more small rural settlements.
Theories of Harappan Decline (UPSC Summary)
| Theory Type | Explanation |
|---|---|
| Ecological/Climatic | River shifts/drying (e.g., Saraswati ), drier climate, floods → farm/water stress ( most accepted ) |
| Economic | Trade with Mesopotamia declines; soil exhaustion; city industries weaken |
| Social/Administrative | Population/resource pressure; limited capacity to coordinate big public works |
| Invasion (older) | Large, sudden conquest not supported by current evidence |
Fun Facts
Some Harappan pottery motifs and religious symbols survive into later Gangetic cultures—showing cultural memory.
Large water-management at Dholavira helped the city last long even under stress—adaptation before decline.
Late Harappan Gujarat shows rural revival , proving the farming base stayed resilient.
Mains Key Points
IVC decline was a gradual, multi-factor shift, not a single catastrophic event.
Ecology (river/climate) + Economy (trade/soil) + Administration (coordination limits) together explain the pattern.
Transition to Late Harappan shows continuity + adaptation : smaller rural units replace mega-cities.
Prelims Strategy Tips
Think De-urbanization from ~ 1900 BCE : cities shrink, villages rise.
Saraswati (Ghaggar-Hakra) river changes are a key ecological factor.
Invasion-only explanations are outdated ; multi-factor decline fits evidence.
Cemetery H, Jhukar, Rangpur = important Late Harappan cultures.
