In 1910, British workers looking for railway ballast uncovered some unusual bricks in Pakistan. What they found changed our understanding of ancient history: a city buried for four thousand years, which would give its name to one of the greatest civilizations in the world.
In 1910, the British engineers building a railway in Pakistan needed ballast. Local workers, pragmatic as ever, were helping themselves to a pile of bricks emerging from a nearby hill. The British, intrigued by the quality of these bricks — fired, uniform, clearly ancient — went to take a closer look. Beneath the hill: an entire city, buried for millennia.
This city was called Harappa. And its discovery would trigger a revolution in our understanding of ancient history.
A civilization that seemed to come from nowhere
Ten years after Harappa, John Faithfull Fleet uncovered Mohenjo-daro. The architecture was the same, the systems of weights and measures identical. The conclusion was clear: these were not isolated city-states, but a unified civilization. Since both sites lay on the Indus River, it was called the Indus Civilization — and since Harappa had been the first discovery, it also came to be called the Harappan civilization.
The excavations that followed — at Mohenjo-daro from 1927 onward under John Marshall, then with Mortimer Wheeler who introduced the square excavation method — revealed something absolutely unprecedented in the history of archaeology.
A civilization without palaces. Without temples. Without armies. Without slaves. Without excessive wealth or apparent poverty, without flagrant inequalities. Without statues glorifying a king or chief. Without pyramids, without ziggurats, without monuments to anyone’s ego.
What archaeologists found at Harappa and across all the other sites was a meticulously planned city, with north-south avenues and east-west streets, houses equipped with bathrooms and sewage systems — for the rich and poor alike —, and water management that many modern cities might still envy.
What the name Harappa conceals
The term “Harappan” has become the standard qualifier for the different phases of this civilization. Archaeologists speak of the pre-Harappan period, the early, mature and late Harappan phases. But the name is almost arbitrary: Harappa was the first city discovered, not the most important. Mohenjo-daro, Rakhi Garhi, Dholavira, Lothal are equally significant.
What matters is what all these cities share: a model of society radically different from anything previously known. No other example of a civilization so developed, so extensive, so prosperous, without centralized power or visible military structure. As I explain in my article Sapta Sindhu: the Seven Rivers, Which Ones and Where, this civilization covered a territory larger than Egypt and Mesopotamia combined.
Harappa and the mature Harappan phase
The mature Harappan phase, extending from 2800 to 1900 BCE, is when the civilization reached its height. Existing cities were transformed, adopting new standardized brick dimensions — 1×2×4 — and new cities appeared. By the end of this period, there were approximately one thousand cities across the territory.
This was also the period when exports reached their records. Overland trade routes, by caravan, and maritime routes linked the Seven Rivers civilization to Mesopotamia, the Arabian Peninsula, Bahrain and Iran. Merchants arrived from all directions at caravanserais set up in front of every major city. A society of commerce, exchange and shared prosperity — a very different picture from the warlike era long attributed to it.
To my mind, this is the true legacy of Harappa: not a name on an archaeological map, but proof that complex, prosperous human societies can exist without domination, without empire, without military glory. A lesson our own era still struggles to hear.
