The Harappan Civilisation
Overview
The Harappan Civilisation (also known as the Indus Valley Civilisation) flourished between approximately 2600 BCE and 1900 BCE in the river valleys of the Indus and its tributaries. It is one of the three great early civilisations of the Old World, alongside Mesopotamia and Egypt. Discovered in the 1920s with the excavation of Harappa (Punjab, now Pakistan) and Mohenjo-Daro (Sindh), the civilisation is noted for its remarkable urban planning, advanced drainage systems, and mysterious script that remains undeciphered.
Discovery and Extent
| Aspect | Details |
|---|---|
| Year of discovery | 1921–1922 |
| Discovered by | Daya Ram Sahni (Harappa), R. D. Banerjee (Mohenjo-Daro) |
| Geographical extent | From Sutkagendor (Balochistan) to Alamgirpur (UP); from Manda (Jammu) to Daimabad (Maharashtra) |
| Major sites | Harappa, Mohenjo-Daro, Chanhudaro, Lothal, Kalibangan, Dholavira |
| Area covered | Approximately 1.5 million sq km — larger than ancient Egypt and Mesopotamia combined |
| River systems | Indus, Ravi, Ghaggar-Hakra, and their tributaries |
Town Planning
The most striking feature of the Harappan Civilisation is its sophisticated town planning.
Key Features of Harappan Cities
| Feature | Description |
|---|---|
| Grid pattern | Streets cut each other at right angles, dividing the city into rectangular blocks |
| Two parts | Citadel (upper town — public buildings) and lower town (residential area) |
| Baked bricks | Standardised size: 7:3:1 ratio — used for walls, houses, and drains |
| Drainage system | Covered drains lined with bricks; soak pits at regular intervals |
| Great Bath | Mohenjo-Daro — a large brick tank, waterproofed with bitumen, possibly used for ritual bathing |
| Wells | Each house had its own well; over 700 wells at Mohenjo-Daro |
| Granaries | Large storage structures for grain (Harappa, Mohenjo-Daro) |
'The Great Bath of Mohenjo-Daro is the finest example of Harappan engineering. It measures 12 m x 7 m, with a depth of 2.4 m, lined with bricks and sealed with natural tar.'
Economy
| Sector | Details |
|---|---|
| Agriculture | Wheat, barley, peas, dates, cotton (earliest known cotton cultivation) |
| Animals | Cattle, sheep, goats, buffalo; possibly elephants and camels |
| Trade | With Mesopotamia (Meluhha in Mesopotamian texts), Oman, Bahrain |
| Crafts | Bead-making (Lothal — bead factory), pottery, shell-working, metalworking |
| Metals | Copper, bronze, tin, gold, silver; iron was NOT known |
| Weights | Standardised cubical chert weights in a binary decimal system (1, 2, 4, 8, 16, 32, 64, 160) |
Society and Culture
| Aspect | Details |
|---|---|
| Social structure | No clear evidence of a ruling class or monarchy; probably a merchant-dominated society |
| Religion | Mother Goddess figurines; Pashupati seal (proto-Shiva); fire altars at Kalibangan; worship of trees and animals |
| Script | Pictographic; found on seals; over 400 symbols; NOT yet deciphered |
| Seals | Steatite seals with animal motifs (unicorn, bull, tiger, elephant) and script |
| Toys and games | Terracotta toys, dice, game boards — suggesting a society that valued leisure |
| Burial practices | Extended burial in wooden coffins; some graves contained pottery and ornaments |
Important Sites
| Site | Unique Feature |
|---|---|
| Mohenjo-Daro | Great Bath, granary, bronze dancing girl statue |
| Harappa | Granaries, working platforms, coffin burial |
| Lothal (Gujarat) | Dockyard (earliest known); bead factory; rice husk |
| Kalibangan (Rajasthan) | Ploughed field surface; fire altars |
| Dholavira (Gujarat) | Unique water management; seven stages of construction |
| Chanhudaro (Sindh) | Bead-making and shell-working centre |
Decline Theories
The Harappan Civilisation declined around 1900 BCE. Several theories exist:
| Theory | Explanation | Evidence |
|---|---|---|
| Floods | Repeated flooding of the Indus | Layers of silt at Mohenjo-Daro |
| Climate change | Drying up of the Ghaggar-Hakra river | Satellite imagery shows dried riverbeds |
| Deforestation | Overuse of wood for brick-making | Reduced forest cover |
| Aryan invasion | Once popular but now largely rejected | No evidence of mass destruction |
| Economic decline | Disruption of trade with Mesopotamia | Decline in foreign goods after 1900 BCE |
Modern scholarship favours a combination of climate change and ecological factors rather than invasion.

-
What is the significance of the Pashupati seal? — It shows a horned figure surrounded by animals, possibly a proto-Shiva, indicating religious beliefs.
Essay Questions (8 marks)
-
Describe the town planning of the Harappan Civilisation. What does it tell us about their level of technological advancement?
-
Discuss the various theories about the decline of the Harappan Civilisation. Which theory do you find most convincing and why?
-
Analyse the economic life of the Harappans with reference to agriculture, crafts, and trade.
Self-Test
-
Fill in the blank: The Harappan script remains ____________. (Answer: undeciphered)
-
True or False: The Harappans knew the use of iron. (Answer: False — they used copper and bronze but not iron)
-
Match the site to the feature: (a) Lothal — Dockyard; (b) Kalibangan — Ploughed field; (c) Dholavira — Water management. (Answer: All correct)
-
Name the site: Which site has a dockyard and is located in Gujarat? (Answer: Lothal)
-
Explain: What does the standardisation of bricks and weights suggest about Harappan society? (Answer: A high degree of organisation, centralised planning, and possibly a unified governing authority.)
-
Critical thinking: Why has the Harappan script not been deciphered, and what would its decipherment reveal? (Answer: No Rosetta Stone equivalent; no long bilingual texts. Decipherment could reveal religious beliefs, governance, and trade relationships.)
Summary
The Harappan Civilisation was one of the most advanced urban cultures of the ancient world. Its planned cities, sophisticated drainage, and wide-ranging trade networks demonstrate a high degree of organisation and technical skill. The civilisation's decline remains debated, but it likely resulted from environmental changes rather than invasion. Harappan culture — especially its town planning and craft traditions — influenced later Indian civilisation. For ICSE students, the Harappan Civilisation is a foundational chapter in understanding the subcontinent's ancient heritage.
