The Rise of The First Cities c. 3300–2600 BCE

Farming had allowed communities to remain in one place. Over the following centuries, some of those villages became larger, more organised and increasingly connected.

Punjab was approaching a turning point. Settlements were no longer simply places to live; they were becoming towns built around trade, specialised work and deliberate planning.

The Early Harappan World

This period is often described as the Early Harappan phase. It was not yet the fully developed civilisation associated with the great cities of Harappa and Mohenjo-daro. Instead, it was the long process through which that civilisation formed.

Communities across the Indus region still had distinct pottery, customs and building traditions. However, they were interacting more frequently. Goods travelled between settlements, decorative styles appeared across wider areas and similar approaches to construction began to spread.

Punjab was part of this much larger network. At Harappa, beside the Ravi River, an earlier settlement expanded into separate mounds surrounded by mud-brick walls. Its growing size suggests that more people, resources and activities were being concentrated in one place.

The First Planned Settlements

At Rehman Dheri, near the Gomal River, a large walled settlement was arranged using streets and lanes that divided it into regular blocks. Its layout appears to have been established early and maintained as the settlement expanded.

At Kot Diji, in Sindh, people constructed substantial defensive walls and built houses using mud bricks on stone foundations. Its distinctive pottery and other cultural features later appeared across much of the Indus region.

Kalibangan, beside the Ghaggar River in present-day Rajasthan, was also fortified and carefully laid out. Streets, houses and walls followed an organised plan, revealing that ideas about managing space were developing across widely separated communities.

These sites were not all located within the Punjab region, but they belonged to the same interconnected world. Their development helps explain the changes taking place at Harappa and throughout the rivers and plains surrounding Punjab.

Work Beyond Farming

Agriculture continued to support most of the population, but larger settlements created room for increasingly specialised work.

Some people became skilled potters, bead-makers, metalworkers, builders or stone-workers. Kilns, workshop debris and partly finished objects suggest that certain areas were used for craft production. Pottery became more carefully made and decorated, while beads, tools, seals and ornaments required knowledge that could be developed over generations.

Specialisation made settlements more dependent upon one another. Farmers produced food, while craftspeople supplied containers, tools and valuable goods. Organising this exchange required storage, transport and some form of local authority.

Trade Across Great Distances

Early Harappan communities were connected through expanding trade routes. Rivers provided natural routes across the plains, while mountain passes linked the Indus region with the highlands to its west and north.

Stone, copper, shells and semi-precious materials travelled far from their original sources. Lapis lazuli and turquoise found at settlements such as Rehman Dheri point towards contact with distant regions. These materials were transformed into beads and ornaments before being exchanged again.

Trade carried more than objects. It also spread techniques, symbols, pottery designs and methods of construction.

Building in Common

One of the most important developments was the growing use of bricks made according to consistent dimensions and proportions.

Standardised bricks made it easier to build straight walls, raised platforms and planned groups of houses. At Harappa, brick proportions established during the Early Harappan period continued into the later city.

This does not mean that every settlement suddenly followed one design. Regional differences remained strong. Yet communities were gradually adopting shared conventions. Fortified boundaries, organised streets, specialised working areas and increasingly uniform building materials all anticipated the cities that would follow.

On the Edge of Urban Civilisation

By around 2600 BCE, the different cultures of the Indus region had begun to converge. They did not disappear, but generations of trade and contact had created a more integrated society.

Punjab’s settlements now contained many of the foundations of urban life: large populations, planned streets, defensive walls, specialised crafts, long-distance trade and standardised construction.

The great Harappan cities were about to emerge but their achievement had been centuries in the making. Punjab was becoming part of one of the world’s earliest urban civilisations.
