Introduction: Nature of Archaeological Knowledge
The Harappan civilisation, also known as the Indus Valley Civilisation, is primarily reconstructed through archaeological evidence rather than written records. Objects such as houses, tools, ornaments, pottery, and seals provide valuable insights into the lives of the people.
The Harappan script, though found on seals and other objects, remains undeciphered, which limits our direct understanding of their language and thought.
Nevertheless, archaeologists have been able to piece together aspects of Harappan society through careful analysis and interpretation of material remains. These interpretations are not fixed; they are subject to change as new evidence emerges.
2. Terminology, Chronology, and Geographical Spread
The term “Harappan Civilisation” is derived from Harappa, the first site where this culture was identified. The civilisation extended over a vast region including parts of present-day Afghanistan, Pakistan, and northwestern India.
The chronological span of the civilisation is divided into three phases:
Early Harappan (c. 6000–2600 BCE): A formative phase marked by the beginnings of agriculture and small settlements.
Mature Harappan (c. 2600–1900 BCE): The urban phase characterised by well-planned cities, trade, and craft specialisation.
Late Harappan (c. 1900–1300 BCE): A phase of decline marked by the disappearance of urban features.
More than 2000 sites have been discovered, most located between the Indus and Saraswati river basins. Major urban centres included Harappa, Mohenjodaro, Dholavira, Rakhigarhi, and Ganweriwala.
3. Origins and Early Development
Archaeological evidence suggests that the Harappan civilisation evolved from early farming communities dating back to around 7000 BCE. These communities were characterised by small settlements, simple structures, and subsistence practices based on agriculture and pastoralism.
Over time, these settlements underwent a gradual transformation, leading to the emergence of large urban centres during the Mature Harappan phase. This indicates that urbanisation was not sudden but the result of long-term internal development.
4. Subsistence Strategies
4.1 Plant-Based Diet
Archaeologists reconstruct Harappan diet through the study of charred grains and seeds, analysed by specialists known as archaeo-botanists. The major crops included:
Wheat and barley
Lentils and chickpeas
Sesame
Millets (especially in Gujarat)
Rice (rare)
This diversity indicates a well-developed agricultural system adapted to different ecological conditions.
4.2 Animal-Based Diet
The study of animal bones by zooarchaeologists reveals that the Harappans consumed:
Domesticated animals: cattle, sheep, goat, buffalo, and pig
Wild animals: boar, deer, and gharial
Fish and birds
While domestication is clearly evident, it remains uncertain whether wild animals were hunted directly or obtained through exchange with other communities.
5. Agricultural Technologies
Although the presence of agriculture is clear, reconstructing exact farming techniques is difficult. However, several indirect pieces of evidence help us understand agricultural practices:
Terracotta models of ploughs found at sites like Banawali suggest plough-based farming.
A ploughed field at Kalibangan shows intersecting furrows, indicating the practice of growing two crops simultaneously.
Representations of bulls suggest the use of oxen for ploughing.
Most Harappan sites are located in semi-arid regions, indicating the need for irrigation. Evidence suggests:
Use of wells for irrigation
Water storage systems such as reservoirs at Dholavira
Limited evidence of canals (e.g., Shortughai)
6. Food Processing and Consumption
Food processing involved the use of tools such as querns, grinding stones, and pounding stones. These tools were made of stone, metal, or terracotta.
According to early excavation reports, different types of querns were used for grinding grains and pounding spices. Archaeologists often use present-day analogies to interpret the functions of such artefacts, although this method has limitations.
Urban Life, Social Structure, and Craft Production
1. Urban Planning and Settlement Layout
One of the most remarkable features of the Harappan civilisation is its well-planned urban centres. Mohenjodaro provides a clear example of such planning.
The city was divided into two main parts:
Citadel: A smaller, elevated area with public buildings.
Lower Town: A larger residential area.
Buildings were constructed on raised platforms, indicating prior planning. The use of standardised bricks with a fixed ratio across sites suggests a high degree of uniformity and coordination.
2. Drainage and Civic Infrastructure
The Harappan cities had an advanced drainage system, considered one of the most sophisticated in the ancient world:
Streets were laid out in a grid pattern, intersecting at right angles.
Drains were constructed along streets and covered with removable slabs.
Each house was connected to the drainage system.
This reflects careful urban planning and concern for sanitation.
3. Domestic Architecture
Houses in the Lower Town reveal important aspects of daily life:
Built around a central courtyard, which served as the focal point of household activities.
Rooms were arranged around the courtyard.
Houses had bathrooms connected to drainage systems.
Many houses had wells and staircases, indicating multi-storey structures.
There was also a clear concern for privacy, as entrances did not directly face the interior.
4. Public Architecture
The Citadel contained structures used for public or ritual purposes:
The Great Bath: A large, watertight tank, possibly used for ritual bathing.
Warehouses: Used for storage of goods.
These structures indicate collective activities and possibly organised authority.
5. Social Differentiation
5.1 Evidence from Burials
Burials provide limited evidence of social differences:
Most burials were simple pits.
Some had brick linings or grave goods such as pottery and ornaments.
Jewellery was found with both men and women.
However, the absence of lavish burials suggests that social inequality was not sharply pronounced, or at least not expressed through burial practices.
5.2 Utilitarian vs Luxury Artefacts
Artefacts are classified into:
Utilitarian objects: Everyday items made from common materials.
Luxury objects: Rare items made from costly materials like gold or faience.
Luxury items are mostly found in large cities, suggesting some degree of social differentiation.
6. Craft Production
Craft production was highly developed and specialised:
Centres like Chanhudaro specialised in bead-making and other crafts.
Materials used included stones (carnelian, jasper), metals, shell, and terracotta.
Techniques involved heating, drilling, polishing, and engraving.
7. Identifying Craft Centres
Archaeologists identify production centres through:
Presence of raw materials
Tools and unfinished products
Waste materials (most reliable indicator)
Craft production took place both in specialised centres and in urban households.
Trade, Authority, Decline, and Discovery
1. Procurement of Materials and Trade
The Harappans used a variety of materials, some locally available and others obtained from distant regions. Transport was carried out through:
Bullock carts (land routes)
Riverine and coastal routes
Settlements were strategically located near sources of raw materials.
2. Long-Distance Trade
There is strong evidence of trade with regions such as:
Oman (Magan)
Bahrain (Dilmun)
Mesopotamia (Meluhha)
Mesopotamian texts mention imports such as carnelian, lapis lazuli, copper, and wood. Harappan artefacts found abroad further confirm these contacts.
3. Seals, Script, and Weights
3.1 Seals
Seals were used for authentication and trade, often carrying animal motifs and inscriptions.
3.2 Script
Undeciphered
Contains 375–400 signs
Likely written from right to left
Found on various objects
3.3 Weights
Standardised system using binary and decimal units
Indicates regulated trade practices
4. Political Organisation
There is no clear evidence of kings or rulers:
No palaces or royal tombs
The “priest-king” figure is speculative
Scholars debate whether the civilisation had:
No rulers
Multiple rulers
A single central authority
5. Decline of the Civilisation
After 1900 BCE:
Cities were abandoned
Urban features disappeared
Society became more rural
Possible causes include:
Environmental changes
River shifts
Overuse of resources
No single explanation is sufficient.
6. Discovery and Interpretation
Early archaeologists like Cunningham failed to recognise its antiquity.
Discovery was confirmed in the 1920s by Sahni and Banerji.
John Marshall announced it as a major civilisation.
Later developments:
Wheeler introduced stratigraphy.
Modern techniques include scientific and genetic analysis.
7. Problems of Reconstruction
Organic materials do not survive.
Archaeological finds are often incomplete.
Interpretations depend on available evidence and may change.
