Discovering the Harappan civilisation: a historiography case study

Detail

This section is not only about the Harappans. It is a case study of how history gets made. The same ruins sat in Punjab for a century. What changed was the method of the people digging. Watch the method change and you watch a civilisation appear.

Cunningham: the text-first archaeologist

• Alexander Cunningham was the first Director-General of the Archaeological Survey of India (ASI). He is called the "father of Indian archaeology".
• His method was text-first. He did not start from the soil. He started from a book, then went to look for the place the book named.
• His chosen books were the travel accounts (itineraries) of Chinese Buddhist pilgrims who came to India between the 4th and 7th centuries CE. Famous ones: Faxian and Xuanzang.
• So his focus was the Early Historic period (about 6th century BCE to 4th century CE) — the age of the Ganga valley cities, Buddhism and the Mauryas.
• Cunningham's own work at Harappa was brief and early: he made short excavations at the site in 1872–73 and found an Indus seal he could not explain. [4]
• Why Harappa slipped past him — three linked reasons:
• Harappa was far off the pilgrim routes. No Chinese traveller described it, so his method could not point to it.
• He believed Indian history began with the Ganga-valley cities. Anything older was, to him, not expected.

• He was given a Harappan seal (noted 1875) and could not place it. The seal had a script nobody could read and an animal style unlike anything Early Historic. He filed it away as an oddity, possibly foreign.

• The brick robbers. Cunningham recorded that Harappa had been badly damaged. Local contractors had carried away its baked bricks for the Lahore–Multan railway line — enough brick to lay about 100 miles of track. Mohenjodaro survived in better shape, which is one reason it later gave up more evidence.

• Lesson for the exam: a source is useless if your method has no slot for it. Cunningham held the seal in his hand and still missed a civilisation.

The announcement: 1921–1924

• 1921 — Daya Ram Sahni excavated at Harappa for the ASI. He found seals in layers of soil that lay far below and far older than Early Historic material.

• Sahni's first big season at Harappa began in 1920, and the ASI's published account covers the work at Harappa from 1920–21 to 1933–34. [3][4]

• From 1922 — R.D. Banerji found similar seals at Mohenjodaro, hundreds of kilometres to the south in Sindh.

• Two far-apart sites, the same kind of seal → the same culture, spread over a huge area. That is the key inference.

• The official ASI report on Mohenjodaro covers Government of India excavations there between 1922 and 1927. [2]

• 1924 — John Marshall, then Director-General of the ASI, announced to the world that a new civilisation had been found in the Indus valley.

• The announcement appeared on 20 September 1924 in the London magazine The Illustrated London News, under the title "A Forgotten Age Revealed". [4]

• Marshall was Director-General of the ASI from 1902 to 1931. [5]

• How the date was fixed. Seals of the same type had already been dug up at sites in Mesopotamia (modern Iraq). Mesopotamian history had a dated king-list. So the Indus seals could be tied to a known date range, proving the two were contemporary — living at the same time.

• This is the method called cross-dating: date an undated culture by an object it shares with a culture whose dates are already known.

• The historian S.N. Roy summed it up: "Marshall left India three thousand years older than he had found her."

Marshall's method — and its costly flaw

• Marshall was India's first professional archaeologist in the modern sense. He cared about everyday life, not only temples, kings and monuments. He wanted to know what ordinary people ate, wore and used.
• But his digging method was wrong. He excavated in horizontal units — he cleared the site level by level across the whole area, treating everything found in one unit as belonging together.
• He ignored stratigraphy — the reading of the layers of soil at a dig, where the oldest layer lies at the bottom and the newest at the top. Layers at a mound are not flat; they dip and cut into each other.
• What was lost:
• If a pot was found in a pit dug down from a later level, Marshall's method recorded it with the deeper material. The object got the wrong date.
• Find-context — the exact layer and surroundings an object came from — was lost forever. You cannot re-dig soil you have already removed.

• Without context you cannot build a sequence: what came first, what came later, how the city changed.

• Takeaway: good questions plus bad method still give bad history. Marshall asked excellent questions about daily life but could not answer them securely.

Wheeler and the stratigraphic correction

• R.E.M. (Mortimer) Wheeler became Director-General of the ASI in 1944. He had been an army brigadier, and he ran digs with military discipline — grids, trained staff, strict recording.
• He insisted that excavation must follow stratigraphy: dig along the natural layers of the mound, not along flat artificial levels, and record which layer every object came from.
• He excavated at Harappa in 1946. His report on that season, Harappa 1946: The Defences and Cemetery R 37, was published in the ASI journal Ancient India, Volume 3. [6]
• In the 1946 work Wheeler dug the so-called fortification walls of Harappa and reached deposits earlier than the Mature Harappan — the Kot Dijian (Early Harappan) levels. [4]

• This mattered hugely: it showed the civilisation had roots and a build-up, and did not simply appear fully formed.

• The wider effect: after Wheeler, Indian archaeology moved from collecting objects to reading sequences. Stratigraphy became the basic discipline of every dig.

Post-Partition: a new map of sites

• 1947 Partition put the two headline sites — Harappa and Mohenjodaro — inside Pakistan.
• Indian archaeologists therefore searched hard inside India for Harappan sites. The result was a wave of major discoveries: Kalibangan (Rajasthan), Lothal (Gujarat), Rakhigarhi (Haryana), Dholavira (Gujarat).
• Political borders changed the research agenda. That is itself a historiography point: what gets excavated depends on who can excavate where.
• Mohenjodaro was inscribed on the UNESCO World Heritage List as the "Archaeological Ruins at Moenjodaro" in 1980. [7]

How the method kept changing after 1947

Read the timeline downwards and you see the tools getting finer, not just the sites getting more numerous.

• Excavation (1921–1960s) — dig the mound, recover plans and objects. Sahni, Banerji, Wheeler, Rao, Lal, Thapar.
• Exploration and survey (1974, 1980) — M.R. Mughal in Bahawalpur walked the dry bed of the old river and mapped hundreds of sites without digging. The German–Italian team at Mohenjodaro in 1980 did a surface survey: they recorded what lay on the ground over the whole city instead of cutting trenches. This shows settlement patterns — how many sites, of what size, where — which digging one mound can never show.
• Specialist science (1986 onwards) — the American project at Harappa from 1986 brought in teams studying bones, seeds, stone tools and craft debris, to reconstruct diet, trade and workshops.
• Archaeogenetics (2013) — Vasant Shinde at Rakhigarhi used ancient DNA from skeletons to ask about the ancestry of the people themselves.
• The pattern: one man reading a pilgrim's travel book (1870s) → a team reading soil layers (1946) → laboratories reading DNA (2013). The evidence was always there; only the questions and the instruments changed.

Why UPSC sets this as a method case study

• It shows sources do not speak on their own. The 1875 seal was mute until someone had a framework that could hear it.
• It shows dating methods: cross-dating by Mesopotamian parallels; relative dating by stratigraphy; later, scientific dating and DNA.
• It shows history is revisable. Indian history was pushed back by roughly 3,000 years by one set of digs.
• It shows non-textual evidence matters. The Harappan script is still undeciphered, so this civilisation is known almost entirely from material remains — bricks, beads, bones, seals — not from any readable text.

Prelims Hooks

• Alexander Cunningham — first Director-General of the ASI, called the "father of Indian archaeology"; used Chinese Buddhist pilgrims' accounts (4th–7th centuries CE) to locate sites.
• Cunningham reported a Harappan seal in 1875 and could not place it; he had made brief excavations at Harappa in 1872–73. [4]
• Harappa's bricks were looted by contractors for the Lahore–Multan railway — about 100 miles of track.
• Daya Ram Sahni excavated Harappa in 1921; R.D. Banerji worked at Mohenjodaro from 1922.
• John Marshall announced the new civilisation in 1924; the article "A Forgotten Age Revealed" appeared in The Illustrated London News on 20 September 1924. [4]
• Marshall was Director-General of the ASI, 1902–1931. [5]
• Contemporaneity with Mesopotamia was proved by matching seals found at Mesopotamian sites.
• S.N. Roy: "Marshall left India three thousand years older than he had found her."
• Mortimer Wheeler — DG of ASI from 1944, former army brigadier; excavated Harappa in 1946; report published as Harappa 1946: The Defences and Cemetery R 37 in Ancient India Vol. 3. [6]
• Wheeler's 1946 trenches reached Kot Dijian (pre-Mature Harappan) deposits. [4]
• Marshall's flaw: dug in horizontal units and ignored stratigraphy, destroying find-context.
• Timeline pairs to memorise: 1955 Lothal (S.R. Rao); 1960 Kalibangan (B.B. Lal, B.K. Thapar); 1974 Bahawalpur (M.R. Mughal); 1990 Dholavira (R.S. Bisht); 1997 Rakhigarhi (Amrendra Nath); 2013 Rakhigarhi archaeogenetics (Vasant Shinde).
• Mohenjodaro entered the UNESCO World Heritage List in 1980. [7]

Mains Points

• Method decides what counts as evidence. Cunningham's text-first approach tied archaeology to the Early Historic period and to sites named in Chinese pilgrim accounts, so the 1875 seal stayed unreadable as history. Only when digging became stratigraphy-driven and independent of texts could a pre-textual civilisation be recognised. Use this as the classic Indian example of a paradigm shift in historical method.
• The 1921–24 discovery restructured the whole Indian past. Before it, Indian history began with the Ganga valley; after it, urban life in South Asia was pushed back to the third millennium BCE and India joined the group of the world's earliest urban civilisations alongside Mesopotamia and Egypt. Link to the cross-dating argument — Indian chronology was anchored to an external, dated civilisation.
• Good intentions versus good technique. Marshall genuinely wanted the history of ordinary people, but his horizontal-unit digging destroyed find-context permanently. Wheeler's method was better but his interpretive frame (fortifications, invasion, "Aryan" destruction) has since been challenged. Useful for an answer on the limits of archaeological interpretation: recovery technique and explanatory model are two separate problems.
• Politics shapes archaeology. Partition in 1947 left the type-sites in Pakistan and drove Indian excavation towards Kalibangan, Lothal, Dholavira and Rakhigarhi, which in turn widened the known extent of the civilisation well beyond the Indus itself. Connect to today's debates on the Ghaggar-Hakra/Saraswati question and on archaeogenetics at Rakhigarhi (2013), where scientific evidence enters a politically charged argument.
