The Indus Valley Civilisation c. 2600–1900 BCE
By 2600 BCE, centuries of agricultural growth, trade and expanding settlements had produced one of the ancient world’s greatest urban civilisations. Across Punjab and the wider Indus region, large cities were built, goods were standardised and communities became connected through a shared system of trade, technology and culture.
A Civilisation of Cities
The civilisation is also known as the Harappan Civilisation - named after Harappa in Punjab, the first of its major cities to be excavated. Harappa was a large urban centre containing raised walled areas, residential neighbourhoods, workshops, wells and extensive drainage.
It belonged to a much wider network. Mohenjo-daro in Sindh became another of its largest cities, while Rakhigarhi, in present-day Haryana, developed into a major eastern centre. Ganeriwala, located in Punjab’s Cholistan region, may also have been among its largest settlements, although much of the site remains unexcavated.
These cities formed part of a civilisation stretching across an enormous area, connected by shared building methods, pottery, seals, weights and styles of craftsmanship.
Planned Urban Life
Harappan cities were built with remarkable organisation. Streets were laid out in planned sections, while houses were commonly constructed from bricks made according to standard proportions. Many homes were arranged around internal courtyards and included bathing areas, drains and access to water.
Covered drains carried wastewater away from buildings and along city streets. Inspection points allowed sections to be cleared when blocked. This required more than skilled construction: it depended upon organised labour, agreed measurements and authorities capable of maintaining public infrastructure.
These were not modern sewer systems, but they represented one of the most advanced approaches to urban water management in the Bronze Age.
Agriculture and Trade
The cities depended upon the surrounding countryside. Farmers cultivated crops including wheat, barley, pulses and sesame; while cattle, buffalo, sheep and goats provided meat, milk, labour and materials. Rivers and seasonal flooding renewed the soil, although communities also had to adapt to shifting channels and changing water supplies.
Surplus food supported people who did not farm directly. Potters, metalworkers, bead-makers, builders and merchants could specialise in particular occupations.
Trade linked settlements across the civilisation and extended far beyond it. Timber, metals, shells and valuable stones travelled between Punjab, Sindh, Gujarat, Balochistan and Afghanistan. Harappan goods and seals have also been found around the Persian Gulf and in Mesopotamia. Mesopotamian records refer to trade with a distant region called Meluhha, widely believed to have included the Indus world.
Crafts and Technology
Harappan craftspeople produced finely painted pottery, carved seals, jewellery, terracotta figures, tools and children’s toys. Beads made from carnelian, lapis lazuli, shell and other materials were shaped and drilled with great precision.
Copper and bronze were used for tools, vessels and ornaments. Cotton was spun and woven into cloth, making the Indus region home to some of the earliest known cotton production. Standardised stone weights allowed goods to be measured consistently across distant settlements.
This standardisation is one of the civilisation’s most striking achievements. Cities separated by hundreds of kilometres still used recognisably similar bricks, seals, weights and manufactured objects.
Writing Without a Voice
The Harappans developed a system of signs now called the Indus script. These symbols appear on seals, tablets, pottery and other objects, usually in very short sequences.
The script has never been conclusively deciphered, and the language behind the signs remains unknown. We cannot read Harappan laws, beliefs, personal names or political records.
Belief and Daily Life
Religious life is equally difficult to reconstruct. Seals portray animals, trees and seated human-like figures, while archaeologists have uncovered figurines, ritual objects and structures associated with water. These interpretations remain debated. Without readable texts, it is impossible to know exactly how the Harappans worshipped or what their images meant.
Everyday objects reveal more. People cooked in household courtyards, stored grain in pottery vessels, wore ornaments, played games and used carts for transport. Differences in house size and access to valuable goods suggest that society was not completely equal, yet the civilisation has produced no unmistakable royal palaces, enormous royal tombs or statues glorifying individual kings.
Archaeologists still debate whether authority belonged to kings, councils, merchants, religious leaders or several regional governments.
Punjab at Its Ancient Height
The Indus Valley Civilisation transformed the Punjab region into part of one of the largest and most sophisticated urban worlds of its time. Its people planned cities, managed water, cultivated vast landscapes, developed specialised industries and traded across extraordinary distances.
Yet its unreadable script leaves its rulers, language and beliefs largely unknown. What survives is the civilisation they built: evidence that, more than four thousand years ago, Punjab stood at the centre of one of humanity’s great experiments in urban life.
