Bricks, Beads and Bones: The Harappan Civilisation

A sophisticated urban culture (c. 2600-1900 BCE) spanning from Afghanistan to Gujarat, known for planned cities and standardized systems.

  1. Chronology and Culture

    The civilization evolved from early farming communities (c. 7000 BCE) into Mature (2600-1900 BCE) and Late Harappan phases.

    • Defining 'Culture' — Archaeologists use 'culture' for a group of distinctive objects (seals, beads, bricks) found together in a specific area and time.
    • Timeframes and Dating — Uses BP (Before Present) and BCE (Before Common Era). The Mature phase (2600-1900 BCE) represents the urban peak.
    • Geographical Spread — Artefacts found in diverse regions including Afghanistan, Jammu, Baluchistan (Pakistan), and Gujarat.
  2. Urban Planning and Architecture

    Distinctive city layouts featuring a Citadel for public use and a Lower Town for residential living, built on mud-brick platforms.

    • Grid Drainage System — Streets and drains laid out in a grid pattern; houses built later to ensure waste water flowed into street channels.
    • The Great Bath — A rectangular tank made watertight with gypsum mortar, likely used for ritual purposes on the Citadel.
    • Standardised Bricks — Uniform brick ratios (4:2:1) used across all settlements demonstrate coordinated decision-making and planning.
    • Public Structures — Includes the massive brick foundations of the Warehouse and buildings with multiple bathrooms for hygiene.
  3. Subsistence and Technology

    A diverse diet of grains and animal products supported by advanced irrigation and tilling technologies.

    • Agricultural Technology — Evidence includes terracotta plough models from Banawali and a ploughed field at Kalibangan with dual furrows.
    • Irrigation Methods — Canals found at Shortughai and masonry reservoirs at Dholavira provided water in semi-arid regions.
    • Dietary Variety — Consumption of wheat, barley, lentils, and millets; rice remains are rare. Cattle and sheep were domesticated.
    • Food Processing — Archaeological finds like saddle querns and curry stones indicate how grains and herbs were processed.
  4. Craft Production and Trade

    Specialised production of beads, seals, and metalwork using materials sourced from distant regions.

    • Production Centres — Chanhudaro was a major centre for bead-making. Centres are identified by waste materials and unfinished objects.
    • Resource Procurement — Lapis lazuli from Shortughai, carnelian from Gujarat, and copper from the Khetri region of Rajasthan.
    • Long-Distance Trade — Contact with Mesopotamia (Meluhha) and Oman, evidenced by nickel traces in copper and Mesopotamian texts.
    • Bead-making Techniques — Varied by material; steatite was moulded as paste while harder stones were ground, polished, and drilled.
  5. Social and Political Organisation

    Evidence of social hierarchy and central authority found in burials, luxury goods, and standardised systems.

    • Burial Practices — Dead laid in pits, sometimes brick-lined. Pottery and ornaments suggest belief in afterlife, but rarely contain wealth.
    • Utilitarian vs Luxury — Social status is inferred from rare items like faience pots found in large cities compared to common clay tools.
    • Seals and Script — Enigmatic right-to-left script and animal-motif seals used to secure goods and identify senders in trade.
    • Standardised Weights — Cubical chert weights followed binary and decimal systems for regulating trade and measuring jewellery.
    • Theories of Authority — Debates include single state vs. multiple rulers. Mentions of 'Palace' and 'Priest-King' remain speculative.
  6. Decline and Discovery

    The transition to 'Late Harappan' cultures and the evolution of archaeological methods over 150 years.

    • Late Harappan Phase — By 1900 BCE, distinctive artefacts like seals and weights vanished, replaced by simpler rural cultures.
    • Causes of Collapse — Climatic change, deforestation, or floods are proposed, but the end of the unifying state was likely decisive.
    • Cunningham's Confusion — First ASI Director-General missed Harappa's significance by relying on later Chinese Buddhist accounts.
    • Evolution of Methods — R.E.M. Wheeler introduced stratigraphy to correct John Marshall's horizontal excavation errors.
    • Religious Interpretation — Speculative identification of 'mother goddesses' and 'proto-Shiva' based on later cultural parallels.

Chapter notes

An exploration of the Indus Valley Civilisation through archaeological evidence, covering urban planning, social structures, craft production, and the eventual decline of this ancient culture.

Terminologies, Places and Time

The Harappan Civilisation, also known as the Indus Valley Civilisation, is named after Harappa, the first site where this unique culture was identified.

Archaeologists use the term 'culture' for a group of objects, distinctive in style, that are usually found together within a specific geographical area and period of time. In the case of the Harappan culture, these distinctive objects include seals, beads, weights, stone blades, and even baked bricks. These artefacts have been found in areas as far apart as Afghanistan, Jammu, Baluchistan (Pakistan), and Gujarat.

The total time span of the civilisation ranges from 6000 BCE to 1300 BCE. The early phase, termed as Early Harappan (6000 BCE-2600 BCE), is a formative phase. Recent archaeological evidence also indicates the emergence of Harappan culture from early farming communities dated around 7000 BCE. The urban phase of the civilisation, termed as Mature Harappan (2600 BCE-1900 BCE), is the most prosperous phase. The decline starts around 1900 BCE, leading into the Late Harappan phase (1900 BCE-1300 BCE).

Dating in archaeology uses specific abbreviations. BP stands for 'Before Present', while BCE stands for 'Before Common Era'. The term 'circa' (abbreviated as c.) is used to indicate approximate dates when exact years are unknown.

Subsistence Strategies and Technology

The Harappans sustained themselves through a diverse diet consisting of plant and animal products, supported by sophisticated agricultural technologies.

Archaeo-botanists have reconstructed Harappan diets by studying charred grains and seeds. Their findings show that Harappans consumed wheat, barley, lentil, chickpea, and sesame. Millets have been found at sites in Gujarat, while rice remains are relatively rare. Animal products were also vital; bones of domesticated animals like cattle, sheep, goat, buffalo, and pig suggest a pastoral component to their economy.

Agricultural practices are inferred from various artefacts. Terracotta models of the plough found at Banawali and Cholistan, along with a ploughed field discovered at Kalibangan, prove that the Harappans used oxen for tilling. The Kalibangan field showed two sets of furrows at right angles, indicating that two different crops were likely grown together simultaneously.

Since many Harappan sites are located in semi-arid regions, irrigation was essential. Traces of canals have been found at Shortughai in Afghanistan. Additionally, water drawn from wells and stored in large masonry reservoirs, like the one found at Dholavira, was used to support farming activities.

Mohenjodaro: A Planned Urban Centre

Mohenjodaro is the most famous Harappan site, showcasing a level of urban planning that was far ahead of its time.

The settlement was divided into two distinct sections: the Citadel and the Lower Town. The Citadel was a smaller, higher area built on mud-brick platforms and was physically walled off. It contained large structures likely used for public purposes. The Lower Town was much larger and served as the residential area. It was also walled, and many buildings were constructed on platforms that required massive amounts of mobilised labour.

Planning is evident in the standardised ratio of bricks used across all settlements, where the length and breadth were four times and twice the height, respectively. Furthermore, the streets and drains were laid out first in a 'grid' pattern, with houses built along them later. This ensured that every house had at least one wall along a street to allow domestic waste water to flow into the street drains.

The drainage system was remarkably complete. Main channels were made of bricks set in mortar and covered with loose bricks or limestone for easy cleaning. Drainage systems were not unique to larger cities; they were found in smaller settlements as well. For example, at Lothal, while houses were built of mud bricks, drains were made of burnt bricks.

The Citadel and Public Architecture

The Citadel housed massive structures that suggest they were intended for special public or ritual purposes.

One of the most significant structures on the Citadel is the Warehouse. While its upper wooden portions decayed long ago, its massive brick foundations remain. Another iconic structure is the Great Bath, a large rectangular tank situated in a courtyard. It was made watertight using bricks set on edge and a mortar of gypsum, reflecting advanced engineering skills.

The Great Bath featured two flights of steps (north and south) and was surrounded by a corridor on all four sides. Rooms were located on three sides, one containing a large well to supply water. The uniqueness of this structure, combined with its location amongst other distinctive buildings on the Citadel, suggests it was used for special ritual baths.

Nearby, a building with eight bathrooms—four on each side of a corridor—further emphasizes the Harappan focus on hygiene and water management. Each bathroom had drains connecting to a central channel running along the corridor.

Tracking Social Differences

Archaeologists use burials and the study of artefacts to determine if social or economic inequalities existed within Harappan society.

In Harappan burials, the dead were generally laid in pits. While some pits were simple, others were lined with bricks, which might indicate social status. Graves often contained pottery and ornaments, suggesting a belief in the afterlife. However, unlike the contemporary pyramids of Egypt, Harappan burials rarely contained enormous wealth, indicating that they did not generally believe in burying precious things with the dead.

Artefacts are classified into two categories: 'utilitarian' and 'luxuries'. Utilitarian objects are items of daily use made of ordinary materials like stone or clay (e.g., querns, pottery, needles). Luxuries are rare objects made from costly, non-local materials or using complicated technologies. For example, miniature pots of faience, likely used for perfumes, are found mostly in large cities like Mohenjodaro and Harappa.

The distribution of these items reveals a pattern: luxury goods are concentrated in large urban centres and are almost absent from smaller settlements like Kalibangan. Gold was also extremely rare and has been found only in hoards, suggesting it was highly precious.

Craft Production and Centres

The Harappans were skilled craftspeople, with specific settlements dedicated almost entirely to production.

Chanhudaro was a tiny settlement (less than 7 hectares) compared to Mohenjodaro, but it was a major centre for bead-making, shell-cutting, metal-working, and seal-making. Beads were made from a variety of materials: semi-precious stones like carnelian and jasper, metals like copper and gold, and materials like faience and terracotta.

The techniques for bead-making varied by material. Steatite, being a soft stone, was easily worked and even moulded from a paste. Harder stones were chipped into rough shapes and then finely flaked, ground, polished, and drilled. Specialised drills have been found at Chanhudaro, Lothal, and Dholavira.

Archaeologists identify production centres by looking for raw materials (stone nodules, copper ore), tools, unfinished objects, and waste material. Waste is often the best indicator; for instance, large pieces of discarded shell or stone at a site clearly mark it as a place of manufacture.

Strategies for Procuring Materials

To support their crafts, Harappans established trade networks and settlements near sources of raw materials.

While clay was local, materials like stone, timber, and metal had to be brought from outside the alluvial plains. They established settlements like Nageshwar and Balakot near the coast for shell. Shortughai in Afghanistan was located near the best source of lapis lazuli, a highly valued blue stone. Lothal provided access to carnelian from Gujarat and steatite from Rajasthan.

Another strategy involved sending expeditions to resource-rich areas. The Khetri region of Rajasthan was a source for copper, while South India provided gold. These expeditions established contact with local communities, such as the Ganeshwar-Jodhpura culture in Rajasthan, which supplied copper to the Harappans.

Long-distance trade also extended to West Asia. Chemical analysis shows that Omani copper and Harappan artefacts both contain traces of nickel, suggesting a common origin. Mesopotamian texts mention trade with 'Meluhha' (likely the Harappan region), referring to it as a land of seafarers and a source of carnelian, gold, and wood.

Seals, Script and Weights

Communication and trade were regulated through a sophisticated system of seals, an undeciphered script, and standardised weights.

Seals and sealings were used to secure goods during long-distance transport. A bag's tie was covered with wet clay and pressed with a seal; if the sealing remained intact, it proved the contents hadn't been tampered with. The seal also identified the sender. Harappan seals often featured an animal motif and a line of writing.

The Harappan script remains 'enigmatic' because it is still undeciphered. It was not alphabetical, as it contains between 375 and 400 signs. It was written from right to left, evidenced by the spacing on the seals. Writing has been found on a wide variety of objects, including tools, jewellery, and even a large signboard at Dholavira.

Trade used standardised weights, usually cubical and made of chert. The lower denominations of weights were binary (1, 2, 4, 8, 16, 32). The higher denominations followed the decimal system (160, 200, 320, 640, etc.). Small weights were probably used for jewellery and beads.

Ancient Authority and Governance

The high degree of uniformity in Harappan artefacts suggests the existence of a central authority, though its nature remains debated.

The extraordinary uniformity in pottery, seals, weights, and the standardised ratio of bricks across vast distances indicates complex, coordinated decision-making. Furthermore, the mobilisation of labour for massive projects like the walls of Mohenjodaro or the platforms at Harappa points to an organised leadership.

Archaeological records offer no clear answers about who held power. A large building at Mohenjodaro was called a 'palace', but no royal treasures were found. A stone statue was named the 'priest-king' based on Mesopotamian parallels, but we don't know if ritual leaders held political power.

Opinions among archaeologists vary. Some believe Harappan society had no single ruler and everyone was equal. Others suggest there were multiple rulers for different cities. A third group argues for a single state, citing the planned settlements and standardised artefacts as evidence of a unified administration.

The End of the Civilisation

By around 1900 BCE, the Mature Harappan culture began to disappear, leading to a transformation into rural 'successor cultures'.

Evidence shows that by c. 1800 BCE, most of the Mature Harappan sites in regions such as Cholistan had been abandoned. In the remaining sites, distinctive artefacts like weights, seals, and special beads vanished. Writing and long-distance trade also ceased. House construction became less sophisticated, and large public structures were no longer built. This period is known as the 'Late Harappan' or 'successor culture'.

Several causes have been proposed for this collapse, including climatic change, deforestation, excessive floods, or the drying up of rivers. While these might explain the decline of specific settlements, they don't fully account for the collapse of the entire civilisation. It is likely that the central unifying element—the Harappan state—came to an end.

The chapter’s Rakhigarhi box presents an interpretation of genetic continuity. Genetic findings must be understood within their sample sizes and methods. Ancestry shared with later populations, or the absence of an ancestry component in an ancient sample, does not by itself establish why cities declined or rule out subsequent migration. Evaluate this box alongside archaeological evidence; it is not proof that a single cause explains the civilisation’s end.

Discovering and Interpreting the Past

The story of how we came to know the Harappans involves the evolving techniques of various archaeologists over the last 150 years.

Alexander Cunningham, the first Director-General of the ASI, missed the significance of Harappa because he relied on Chinese Buddhist accounts from a much later period. He mistakenly thought Indian history began in the Ganga valley. It was only in the 1920s, when Daya Ram Sahni and Rakhal Das Banerji found seals at Harappa and Mohenjodaro, that the true antiquity of the site was realised.

In 1924, John Marshall announced the discovery of the Indus Civilisation to the world. However, Marshall excavated in horizontal units, which mixed up artefacts from different time layers. R.E.M. Wheeler later corrected this by introducing 'stratigraphy'—the study of layers—which allowed for a more accurate chronological sequence of the finds.

Interpreting religious practices is particularly difficult. Archaeologists often look for parallels in later traditions. For example, female figurines are called 'mother goddesses', and a figure on a seal in a yogic posture is called 'proto-Shiva'. However, these interpretations remain speculative as the script cannot be read to confirm these beliefs.
