Mohenjo-daro: the great Indus city that had neither king nor palace

Picture a city of baked brick spreading over more than a square kilometre, crossed by broad straight avenues, fitted with a drainage system that many nineteenth-century cities would have envied. Picture tens of thousands of inhabitants, trade that linked this settlement to distant Mesopotamia, craftsmen who mastered copper, carnelian and faience. Now look for the king's palace. Look for the great temple, the ruler's gilded tomb, the colossal statue of the conqueror. You will not find them.

It is this absence, both unsettling and fertile, that makes the Indus valley one of the most hotly debated grounds in world archaeology today.

A megacity born without a crown

It reached from present-day Afghanistan to western India, taking in almost all of Pakistan. Mohenjo-daro, whose name means "the mound of the dead" in the Sindhi language, was one of its two presumed capitals, alongside Harappa. Rediscovered in the 1920s by archaeologists of the Archaeological Survey of British India, the city immediately astonished observers by its scale and its organization.

Sir John Marshall, who led the first major excavations, was struck by a fact that has fed reflection ever since: the city yielded no palace, no identifiable temple, no princely burialBurialThe intentional deposition of a body, sometimes with offerings; a marker of symbolic behaviour.→ laden with gold and offerings, no statue of a king or a general.¹ Nothing, in short, of what archaeologists had learned to recognize as the signature of a dominant elite in Egypt or the Near EastNear EastA region of western Asia (Levant, Mesopotamia, Anatolia, Iran), cradle of the Neolithic revolution, agriculture, the first cities and writing.→. Marshall concluded that Indus society appeared remarkably free of conspicuous inequality. A century later, that intuition remains at the centre of the debate, and recent work has even given it an unexpected new vigour.

A city on a grid, conceived as a whole

What strikes you first at Mohenjo-daro is the order. Far from the organic tangle of alleys so often associated with ancient cities, the settlement displays a grid town planUrban planningThe planned organisation of urban space (streets, districts, water and drainage networks, public buildings); the Indus Civilisation offers an early and remarkable example.→, with large arteries aligned to the cardinal points and secondary streets dividing the districts into regular blocks. Such planning implies an overall vision, a shared will to organize space before even building. The bricks themselves, kiln-fired, follow standardized proportions, often in a ratio of one, two, four between thickness, width and length, and this from one end of the civilization to the other.

More revealing still are the houses. At Mohenjo-daro, domestic architecture consists of dwellings of broadly comparable size, organized around inner courtyards, often with an upper storey. Some are larger than others, of course, for no human society is perfectly uniform. But one does not find the crushing contrast seen elsewhere between the sprawling palace of the ruler and the hovels of the common people. The archaeologist Jonathan Mark Kenoyer, who long excavated Harappa, stresses that the Indus cities seem to have grown gradually, their inhabitants raising and enlarging their platforms and walls over the generations, within a surprisingly stable urban framework.³ The whole conveys the image of a society in which differences of status, if they existed, were not expressed through the architectural crushing of one's neighbour.

Water for all: wells, baths and sewers

If the genius of Mohenjo-daro had to be summed up in a single word, it might well be water. The city had a supply and drainage network of a sophistication that leaves visitors incredulous. Wells, built from wedge-shaped bricks to resist the pressure, were distributed throughout the city, so that almost no inhabitant was far from a source of clean water. Several hundred have been counted across the settlement.

But the most astonishing thing is that nearly every house had its own bathroom, paved with closely fitted bricks, sometimes on an upper floor, from which waste water was carried away by terracottaTerracottaClay shaped and then hardened by firing; the material of pottery, bricks and figurines, ubiquitous since the Neolithic.→ pipes or chutes that joined the street drains.⁵ These drains, covered with slabs or bricks, formed a genuine municipal sewer network, with inspection openings for maintenance and settling basins. Nothing comparable would exist before the Roman Empire, several millennia later. Yet, and this is where the social reading becomes fascinating, this access to water and sanitation was not reserved for a privileged quarter. It was generalized, distributed across the entire city. In most early civilizations, hydraulic comfort is a marker of rank. At Mohenjo-daro, it looks like a collective amenity, almost a shared urban right.

The Great Bath, a monument that is not a temple

On top of the western mound, often called the citadel, stands the city's most famous structure: the Great BathGreat BathA large watertight baked-brick pool on the citadel of Mohenjo-daro, probably used for ritual or collective water-related purposes.→. It is a watertight pool roughly twelve metres by seven, more than two metres deep, built of baked brick bonded with bitumen to ensure waterproofing and surrounded by a colonnaded gallery. A stairway descends into the water at each end. It is often regarded as the earliest known example of a public pool of this kind.

What was it for? Most specialists see it as a place with a ritual or ceremonial vocation, perhaps linked to practices of purification by water, a theme that would later run through the whole culture of the subcontinent. But, and this is crucial, the Great Bath is not a temple in the Mesopotamian or Egyptian sense. There is no enclosed sanctuary, no statue of a deity, no blood-stained altar, no clergy identifiable through dedicated monumental buildings. As one National Geographic commentator put it, it is "the closest thing to a temple" in the city, and it remains a pool, that is, an installation turned towards water and, in all likelihood, towards some form of collective participation.⁵ Even the most imposing monument at Mohenjo-daro refuses to designate a master.

Weights, measures and writingWritingA system of conventional signs used to fix language or information durably; its appearance (c. 3300 BC) marks, by convention, the end of prehistory.→: order without a sceptre

The absence of a king does not mean the absence of organization. On the contrary, the Indus civilization displays a standardization that commands admiration. Weights, most often cut from a grey flintFlintA hard, brittle siliceous rock, knapped by prehistoric people to produce blades, points and sharp tools.→ called chert, follow a remarkably regular binary progression, one, two, four, eight, sixteen, thirty-two, before switching to a decimal system for large values. Their uniformity is such, from one site to another over hundreds of kilometres, that the first archaeologists imagined they came from a single central workshop.⁴ Bricks, lengths and well diameters likewise obey common norms.

This rigour poses a formidable puzzle. Standardizing weights and measures across so vast a territory usually implies an administration, and therefore a power. And yet that power remains nowhere to be found in the ground. The Indus scriptIndus scriptA system of about 400 signs engraved on Harappan seals, tablets and pottery, undeciphered to date for lack of a bilingual text.→, engraved on nearly four thousand objects, mostly steatite seals, has still not been deciphered. Several hundred signs have been counted, but the inscriptions are very short, on average a few characters, which makes any decoding terribly difficult. We cannot, therefore, read the names, the titles, or the possible proclamations of this civilization. We do not even know for certain whether it is a fully transcribed language or a more limited system of symbols. The result is that Mohenjo-daro speaks to us through its streets, its drains and its weights, but keeps silent about those who may have governed it. Order is visible everywhere, the sceptre nowhere.

The inverted mirror of Mesopotamia and Egypt

To measure how far the Indus stands apart, one need only look at its great contemporaries. In Mesopotamia, in the same centuries, the cities of Ur, Uruk and Lagash are dominated by the ziggurat, a stepped temple that crushes the landscape and proclaims the power of the gods and of their servants, priests and kings. The royal tombs of Ur yielded gold ornaments, inlaid harps, and even human sacrifices accompanying the deceased into the afterlife. Mesopotamian art tirelessly celebrates the ruler, the warrior, the god, in victory stelae where the king tramples his enemies.

In Egypt, the contrast is more striking still. At the time Mohenjo-daro was flourishing, the pharaohs of the Old KingdomOld KingdomThe first great period of unified pharaonic Egypt (c. 2700-2200 BC, 3rd-6th Dynasties), the golden age of the great pyramids and of a strongly centralised state.→ were raising the pyramids of Giza, mountains of stone meant to shelter a deified royal body for eternity. All of Egyptian society is conceived as a pyramid, in the literal and figurative sense, with the pharaohPharaohThe title of the ruler of ancient Egypt, regarded as a living god guaranteeing cosmic order (Maat), supreme head of state, army and worship.→ at the summit, an intermediary between men and gods. The image of the king is everywhere: colossal, repeated, overwhelming. Against all this, the silence of the Indus becomes deafening. No pyramid, no ziggurat, no royal mausoleum, no triumphant king carved in stone. The famous statuette known as the "priest-king", a small steatite figure seventeen centimetres high with half-closed eyes, is in fact a name given by the excavators, not a certainty: nothing proves that it represents a ruler. Where Mesopotamia and Egypt scream power, the Indus keeps it silent.

The proof from the houses: measuring inequality

For a long time this absence of an elite rested on an impression, that of the first excavators. In 2026, a study tried to quantify it. Researchers, among them Adam Green and Cameron Petrie, applied to Mohenjo-daro a method already tested on other ancient societies: measuring the floor area of dwellings and deriving from it a Gini coefficientGini coefficientA statistical measure of inequality, from 0 (perfect equality) to 1 (extreme concentration), applied here to house sizes.→, that economic indicator which puts a figure on inequality, from zero, perfect equality, to one, extreme concentration.² The reasoning is simple: in a highly unequal society, a few enormous residences sit beside a multitude of hovels, and the gap in floor area explodes.

The result surprised even the authors. Not only was the inequality of house sizes at Mohenjo-daro low, but it appeared to decrease over the centuries, even as the city grew more prosperous and its plan more orderly. In its later phases, the wealth gap approached levels comparable to those of the very first farming villages, long before urbanization. Compared with its neighbours in Mesopotamia or with the Aegean world, the city came out markedly more equal. In other words, the great Indus city may have prospered not despite low inequality, but perhaps partly thanks to a broad spread of wealth and access to resources. It is an idea that unsettles the intuition that urban growth necessarily goes hand in hand with the concentration of power and the widening of gaps.

Real equality or an invisible elite? The great debate

Should we then turn Mohenjo-daro into an egalitarian utopia before its time? Archaeologists urge caution, and the debate is lively. In an article with a deliberately provocative title, "Killing the Priest-King", Adam Green argues that the Indus civilization demonstrates that a ruling class is not a prerequisite for social complexity, and that Marshall's intuition about the absence of marked political and economic inequality was basically correct.¹ In his view, archaeologists have too often tried to make the Indus resemble Egypt or Mesopotamia, postulating elites that cannot be found, out of simple loyalty to the idea that any complex society must be stratified.

Other researchers see it differently. The archaeologist Massimo Vidale, in particular, argues that some large buildings may have been elite residences, even "palaces" serving an elite that was not single but plural, organized as a heterarchyHeterarchyAn organization of power into several interlocking centres of equal rank, rather than a single vertical hierarchy.→, that is, as multiple, interlocking powers rather than a single hierarchy. He also points to a major bias: the excavated sectors are the raised mounds, perhaps precisely the wealthier quarters, while the ordinary population may lie beneath several metres of silt deposited by the Indus, out of reach of the excavations. The apparent equality would then be, in part, an artefact of what we are able to see. Many agree on one point: the Indus probably had no single king, but that does not prove it was a fully equitable society. Between the absence of evidence of hierarchy and evidence of an absence of hierarchy, the nuance is immense. What Mohenjo-daro offers us, in the end, is less an answer than a lesson in modesty: our models of the first civilizations, built on pharaohs and ziggurats, may not be universal. A great city could be born, grow and prosper according to an entirely different grammar of power, one that its mute writing still prevents us from reading. And it is precisely that silence which, a century after Marshall, continues to fascinate.
