The Mound and Its Name

The name is Sindhi. Mohenjo-daro — the Mound of the Dead. It is a name given by local inhabitants to the low, weathered mounds that rose from the alluvial plain of the lower Indus, near the modern city of Larkana. For centuries, the mounds were thought to be nothing more than the remnants of a medieval settlement. They were not.

In 1922, R.D. Banerji, an officer of the Archaeological Survey of India investigating what he believed to be a Buddhist stupa on the upper mound, realized that the remains beneath the stupa were vastly older than any Buddhist structure. What lay below was not medieval, not classical, not even Iron Age. It was Bronze Age. It was a city of the third millennium B.C. — one of the largest and most sophisticated urban centres of the ancient world.

Mohenjo-daro is, by any measure, one of the most important archaeological sites on earth.

The City Revealed

The excavations at Mohenjo-daro — conducted by John Marshall, Ernest Mackay, and later Mortimer Wheeler over the 1920s through the 1940s, with subsequent Pakistani campaigns — revealed a city of approximately 250 hectares, with an estimated peak population of 30,000 to 50,000.

The city was organized into two principal areas: a raised "citadel" mound to the west and a larger "lower city" to the east. The citadel contained several of the most celebrated structures:

The Great Bath — a large, carefully waterproofed tank, measuring approximately 12 metres by 7 metres, lined with closely fitted bricks sealed with bitumen. Its function is debated, but the prevailing interpretation is that it served a ritualistic or ceremonial purpose related to water purification.

The Granary — a series of massive brick platforms originally interpreted as grain storage facilities. This interpretation has been challenged; the structures may have served other storage or administrative functions.

The College of Priests — a large residential building so named by the excavators, though there is no actual evidence that priests inhabited it.

The lower city was densely built, with houses of fired brick arranged along streets that intersected at approximately right angles. Many houses had internal courtyards, wells, and bathing platforms. Nearly every house was connected to a sophisticated drainage system — covered brick drains that ran beneath the streets, collecting wastewater and channelling it to soak-pits or outflows beyond the city.

This drainage system is, in engineering terms, unmatched by any other Bronze Age urban culture. It implies a level of civic organization and public health awareness that would not be seen again in South Asia for two thousand years.

Art and Artefact

Mohenjo-daro yielded a rich assemblage of artefacts. Among the most famous:

The Priest-King — a small steatite bust of a bearded man wearing a cloak decorated with trefoil patterns. The designation "Priest-King" is conventional and speculative; nothing is known about the figure's actual identity or role.

The Dancing Girl — a small bronze figurine of a young woman standing with one hand on her hip, wearing a stack of bangles on one arm. Despite its diminutive size, it is one of the most celebrated pieces of ancient sculpture from South Asia.

Seals — thousands of steatite seals bearing animal motifs and Indus script inscriptions, similar to those found at Harappa.

Pottery, beads, weights, tools, and ornaments — in vast quantities, documenting the daily life, trade connections, and aesthetic sensibilities of the city's inhabitants.

The Undeciphered Question

Like Harappa, Mohenjo-daro has yielded thousands of inscriptions in the Indus script. Like those from Harappa, they remain undeciphered. The inscriptions are almost exclusively found on seals and seal impressions, and they are invariably short. No bilingual text — no Rosetta Stone — has been discovered.

This is the central frustration of Indus Valley studies. We can describe the cities in extraordinary physical detail. We can reconstruct their trade networks, their diet, their craft technologies. But we cannot read their words. We do not know what they called themselves. We do not know what they called their city. "Mohenjo-daro" is a name given by people who came later. The city's own name is lost.

Decline and Abandonment

Mohenjo-daro was not destroyed by conquest — at least, not by any conquest visible in the archaeological record. Wheeler's once-famous theory of an Aryan invasion, based on scattered skeletal remains found in the upper levels, has been abandoned by most scholars. The skeletons show no clear evidence of massacre, and the broader theory of a violent Aryan destruction of the Indus cities has been superseded by models emphasizing environmental and climatic factors.

The most probable cause of Mohenjo-daro's decline is a combination of hydrological change — shifts in the course of the Indus River, increased flooding, and possible tectonic activity — and the general systemic stress that affected the entire Indus Valley Civilization in the late third and early second millennium B.C. By approximately 1900 B.C., the city was in serious decline. By 1700 B.C., it was effectively abandoned.

Conservation Crisis

Mohenjo-daro was inscribed on the UNESCO World Heritage List in 1980 — one of the first sites in Pakistan to receive this recognition. But inscription has not guaranteed preservation.

The site faces a constellation of threats. Salinization — the rise of salts through the exposed brick structures due to a high water table and inadequate drainage — is the most destructive ongoing process. The salts crystallize within the brickwork, causing it to crumble and flake. Monsoon flooding periodically inundates the lower areas of the site. Weathering from extreme summer heat accelerates deterioration.

Multiple conservation campaigns — Pakistani, international, and UNESCO-coordinated — have addressed aspects of the problem. A major UNESCO-funded project in the 1970s and 1980s attempted to lower the water table through a system of tube wells. The results were mixed. The fundamental challenge — that the site is an excavated, exposed, unfired-and-fired brick city sitting on a floodplain with a rising water table — remains unresolved.

In 2012, heavy monsoon flooding again threatened the site, prompting renewed international concern. The Pakistan government allocated additional funds. Conservation continues, but the long-term prognosis is uncertain.

Why Mohenjo-daro Matters

Mohenjo-daro matters because it proves something that needed proving: that the earliest cities were not all in Mesopotamia. That the impulse toward urban life — toward planned streets, public sanitation, standardized measurement, organized trade — arose independently in the Indus valley, at the same time, with the same sophistication, and in some respects with greater civic orderliness.

It matters because it is beautiful. The geometry of its streets, the discipline of its drains, the quiet elegance of the Dancing Girl — these are not crude. They are refined. They speak of a civilization that valued order without ostentation, cleanliness without monumentality, precision without grandiosity.

And it matters because it is fragile. The salt creeps upward. The river remembers its old channels. The bricks, fired four thousand years ago, crumble in the Sindh heat. If Mohenjo-daro is lost — and the possibility, though distant, is not fanciful — something irreplaceable will have been subtracted from the human record.
