Indus Valley Civilisation – Comprehensive Study Notes

Page 1

Introduction to the idea of “civilisation”
- A civilisation = a highly-developed, organised society living in a definite place for a definite span of time.
- Emerged only after humans adopted a settled life based on surplus farming and economic stability.
Common river-valley origin
- Earliest four civilisations all grew up on the banks of great rivers; map on next page pin-points locations.
Four classic river civilisations
- Egyptian → Nile Valley
- Mesopotamian → $\text{Tigris} + \text{Euphrates}$
- Indus Valley → River Indus (and later Saraswati/ Ghaggar–Hakra)
- Chinese → Hwang-Ho / Yellow River
Definition of chief “features of a civilisation” foreshadowed (detailed in Page 2).
Chronological band for Indus Valley Civilisation (IVC): $2500\text{ – }1500\,\text{BCE}$ appears on timeline stretching $4000\text{ – }500\,\text{BCE}$ .

Why river valleys?
1. Annual floods leave fine silt → natural fertiliser.
2. Floodwater stored/ diverted to irrigate dry-season fields.
3. Fish = supplementary food.
4. Rivers = natural waterways → trade + movement.
“Civilisation” etymology → Latin civitas, “city-dwellers”; hence urban focus.
Enumerated chief features of any civilisation
- $\mathbf{Urban\ settlements}$ (planned cities).
- Specialisation of labour/ crafts.
- Inter-city trade networks.
- Script for recording government orders & accounts.
- Social stratification/ classes.
- Organised government for law, order, taxation.
- Distinct religion & arts.
- Conscious application of technology to tame Nature.
“Time-to-Think” box – asks students to analyse their own city; shows relevance to modern urban geography.

Discovery narrative
- 1920: labourers removing baked bricks for Lahore–Multan railway near Harappa.
- Alerted Archaeological Survey of India (ASI).
- Excavations by Dayaram Sahni (Harappa, 1921) & Rakhal Das Bannerji (Mohenjodaro, 1922).
- Upshot: proof of a sophisticated pre-Aryan civilisation; shattered notion that Indian history begins with Vedic Aryans.
Alternative names
- “Indus Valley Civilisation” (geographical), “Harappan Civilisation” (first site excavated), sometimes “Saraswati Civilisation” (due to sites along dried Saraswati/ Ghaggar).
Dating
- Broad archaeological bracket $\approx 2500\text{ – }1500\,\text{BCE}$ (contemporary with Egyptian Old/Middle Kingdoms and Sumerian & early Chinese dynasties).
Sources of knowledge
- Script undeciphered → historians rely mainly on material culture: pottery, seals, tools, ornaments, town ruins, graves, etc.

Page 4 – Urban Planning (Macro level)

Twin-section city layout
- Citadel (western/raised) vs Lower Town (eastern/flat).
- Streets laid out at right angles → grid (comparable to modern Chandigarh).
Citadel details
- Rectangular platform $\approx 12\,\text{m}$ high.
- Fortified by thick brick wall & watchtowers → flood protection + defence + social segregation.
- Contained granaries, assembly/ town halls, manufacturing workshops & elite residences.
Public structures
- Great Bath (Mohenjodaro): $55\,\text{m} \times 33\,\text{m}$ inner courtyard, stepped access, bitumen-sealed brick floor; likely ritual purification rather than leisure.
- Great Granary (Harappa): two blocks of six halls each; air-ducts for ventilation; adjacent circular platforms for threshing grain delivered as tax.
- Pillared Hall (Mohenjodaro): $70\,\text{m} \times 23\,\text{m}$ , 20 brick pillars → probable assembly or cultural venue.
- Dockyard (Lothal): brick-lined basin linked to Gulf of Cambay by channel; dry-dock features, ship-repair evidence → overseas trade.

Page 5 – Urban Planning (Micro level)

Residential quarters
- Houses of baked & sun-dried bricks, single/ double storey, flat timber roof, centred on private courtyard.
- Standard house modules = living rooms, kitchen hearth, bathroom; many had own well.
- Main door opened onto side-lane, ensuring privacy & minimising dust from main street.
Street design
- N–S & E–W axes; widths $4\text{ to }10\,\text{m}$ ; paved for bullock-cart passage.
- Evidence of lamp-posts → street-lighting.
- Dustbins set at intervals → municipal sanitation awareness.
World-class drainage
- Covered brick drains flanking streets; domestic drains emptied into larger ones; removable stone slabs for de-silting.
- Unified design across sites signals central planning & civic sense.

Page 6 – Social, Political & Occupational Pattern

Political organisation (inferred)
- Uniform metrology, city plans & brick ratios $1 : 2 : 4$ suggest central authority or a network of interacting city-states with shared standards.
- Citadel occupancy of elites = ritual or administrative centre.
Social groups
- Nobility/ ruling class.
- Priests? (priest-king figure).
- Merchants, artisans, farmers, labourers.
Writing system
- Undeciphered pictographic script (~400+ signs); written right-to-left (proved by sign crowding); appears on seals, pottery, copper tablets.
Dress & adornment
- Earliest cotton cultivators; wool also used (from sheep/ goat).
- Men: loin-cloth + shawl; women: knee-length skirt.
- Ornaments: bangles, necklaces, beads, earrings (materials: gold, copper, faience, shell, semi-precious stones).
Craft specialisation
- Pottery: red ware with black painted geometric/ animal motifs, finely fired & sometimes glazed.
- Metallurgy: copper-bronze tools, carts, animal figurines; famous “Dancing Girl” bronze (~11 cm).
- Bead-making (Chanhudaro, Lothal), seal-carving (steatite), shell inlay (Nageshwar).

Page 7 – Economy: Agriculture, Animal Husbandry & Trade

Agriculture
- Crops: wheat, barley, cotton (unique), millets, field peas, sesamum; later evidence of rice (Lothal) and cotton brightens textile trade.
- Tools: wooden plough with copper bits, terra-cotta sickles; irrigation via channels & embankments.
- Annual river inundation eliminated need for artificial fertiliser.
Animal husbandry
- Domesticated: humped zebu cattle, buffalo, sheep, goat, pig, dog, camel, donkey, elephant.
- Horse absent (contrary to later Vedic age).
Trade & metrology
- Internal: land routes linking Punjab–Sindh–Gujarat; uniform cubical weights (binary & decimal series $1, 2, 4, 8, 16\ldots$ up to $64$ units).
- External: Mesopotamian cuneiform texts mention “Meluhha” (widely accepted as Indus region). Finds of Harappan seals at Ur, Susa; Mesopotamian cylinder seals at Lothal.
- Commodities exchanged: cotton textiles, beads, lapis lazuli, carnelian, ivory, timber, seashell, possibly rice & dates.
- Transport media: bullock carts over land; riverine boats; ocean-going barges using dock at Lothal.
Seals
- >2,000 discovered; mostly steatite square with animal motif (unicorn, humped bull, elephant, tiger, rhinoceros) + legend.
- Holes behind indicate use as amulets, identification tags or trade stamps sealing bales/ jars.

Page 8 – Religion & Culture

Deities & cult objects
- Mother-Goddess (terra-cotta figurines with exaggerated hips/ bosom) → fertility cult.
- Proto-Shiva/ Pashupati seal: horned, three-faced yogic figure surrounded by wild animals (tiger, elephant, buffalo, rhinoceros, deer) → early form of $\text{\underline{Shiva}}$ as Lord of beasts.
- Sacred animals/ trees: bull, unicorn, humped zebu, peepal tree depicted on seals.
- No definite temples; religion practised in household shrines & public ritual baths (Great Bath).
Funerary practice
- Burials oriented N–S; grave goods limited (pottery, ornaments) → belief in after-life but absence of ostentatious wealth display.
Iconic art pieces
- Priest-King bust (Mohenjodaro): steatite, half-closed eyes, trefoil motif shawl.
- Bronze Dancing Girl: dynamic tribhanga posture, armful of bangles, evidence of lost-wax technique. Try again with the following changes:

Page 9 – Causes of Decline

Multiple hypotheses (no single agreed cause; likely multi-factorial around $\approx 1900\,\text{BCE}$ ):

Tectonic & fluvial changes
- Earthquakes altered river courses (Indus, Saraswati), causing water-logging in some areas & desertification in others.
Recurrent floods
- Archaeological layers in Mohenjodaro show silt deposits & rebuilding 7–9 times.
Climatic shift
- Decrease in monsoon intensity → aridity → agricultural collapse (links to modern SDG 13 discussion).
Ecological degradation
- Over-exploitation of forest for fuel/ bricks led to deforestation & soil erosion.
Epidemics or catastrophic fire
- Mass burials & abrupt abandonment hints.
External aggression
- Aryan migration/ small‐scale conflicts (no firm massacre evidence).
  Outcome: Gradual eastward migration; cultural continuity into Late/ Post-Harappan cultures (Cemetery-H, Bara, Rangpur) & influence on later Vedic settlements.

Q3 Mother-Goddess worship: fertility & prosperity; soot marks indicate incense burnt in rituals.
Q4 script notes: pictographs (~100 signs originally recognised; now >400); written right-to-left; examples on seals; undeciphered.

Page 15 – Cross-Word Exercise (Worksheet II)

Across & Down answers (knowledge reinforcement): PICTOGRAPH, CHINESE, HARAPPA, AGRICULTURE, CITADEL, PASHUPATI, LOTHAL, TERRACOTTA, GREAT BATH, SEALS.

Page 16 – Debrief & Outstanding Problems

Indus script still undeciphered: cracking it would illuminate political system, belief, literature, possibly links to later Dravidian or Munda languages.
Archaeologists continue to survey using satellite imagery & geo-physics to map buried settlements along now-dried Saraswati (Ghaggar-Hakra) palaeo-channel.

Page 17 – Key Take-Aways & Modern Significance

Planned urbanism with drainage & waste management parallels modern civic challenges; inspires contemporary town-planners.
Trade globalisation is not new; Indus–Mesopotamia exchange foreshadows today’s international maritime commerce.
Climate resilience: IVC decline reminds us that environmental mis-management & climate change can undo centuries of progress—link to SDG 13.
Cultural continuity: motifs like the unicorn, yoga-like Pashupati pose, use of cotton, terracotta figurines surface in later Indian art & ritual; showcases enduring civilisational threads.
