Meaning

Mortimer Wheeler (R.E.M. Wheeler) was a British archaeologist and former army brigadier. He became Director-General of the Archaeological Survey of India (ASI) in 1944, and he changed how Harappan sites were dug by following the stratigraphy (the layers of a mound). He is also known for a famous but now rejected idea: that Aryan invaders, led by the god Indra, destroyed the Harappan cities.

He matters for two reasons. His method made Harappan archaeology more scientific. His invasion theory, and the way later scholars overturned it, is a standard example of how interpretations in history change.

Explanation

Background: the problem he fixed

Earlier excavators, under John Marshall, dug in uniform horizontal lines across a whole mound.
This was a mistake. Objects from different layers, and so from different time periods, got mixed together.
As a result, the exact layer and date of many finds was lost.

His method: stratigraphy and military precision

Stratigraphy (studying the layers of a mound one by one, because each layer belongs to a different period): Wheeler said excavators must follow the natural layers of the mound instead of digging mechanically.
As an ex-army brigadier, he brought military precision to archaeology: careful planning, discipline and exact recording.
He took over the ASI in 1944 and excavated at Harappa in 1946.

The invasion thesis (1947)

The starting point: in 1925, John Marshall's excavation found 16 skeletons in "Deadman Lane" at Mohenjodaro.
Wheeler's link (1947): he connected these skeletons to the Ṛig Veda.
The Ṛig Veda mentions pur (forts).
It calls Indra puramdara ("fort-destroyer").
So Wheeler argued that the dead were victims of an Aryan attack.
His famous line: "On circumstantial evidence, Indra stands accused."
He suggested the bodies lay in the streets "where they were slain" [2].

Result: the thesis is rejected

1964: George F. Dales answered Wheeler in his paper "The Mythical Massacre at Mohenjodaro" [2].
Dales showed that:
the skeletons belonged to different time periods, so they did not die in one event;
the burials were careless and without ceremony, not like battlefield dead;
there was no destruction layer and no burnt city;
there were no armoured warriors and no sign of a last defence of the citadel [2].
Dales also said the bodies were scattered across the site, not lying in the streets. Some may be later deaths with no link to the others, for example victims of hill bandits [2].
Harappan sites show no army and no weapons of war, so the invasion idea has no support.
Today scholars agree there was no single cause of the decline. The causes most widely accepted now are a climate shift from c. 2200 BCE and the drying of the Sarasvatī.

Time, place and evidence

Period: Wheeler's work in India was in the 1940s. He became ASI Director-General in 1944, excavated at Harappa in 1946, and put forward the invasion thesis in 1947. His subject was the Harappan Civilisation (c. 3500–1300 BCE; mature phase 2600–1900 BCE).
Sites: Harappa, where he excavated, and Mohenjodaro, where the "Deadman Lane" skeletons came from.
Key people: John Marshall, who found the skeletons in 1925; Mortimer Wheeler, who proposed the invasion thesis in 1947; George F. Dales, who refuted it in 1964.
Evidence:
Archaeological: the 16 skeletons. There was no destruction or burn layer and no weapons of war.
Textual: Ṛig Vedic references to pur and to Indra as puramdara.
Re-analysis: Dales' 1964 paper [2].

Don't confuse with

John Marshall: Marshall found the 16 skeletons at Mohenjodaro in 1925 and dug in horizontal units. Wheeler brought in stratigraphic digging and turned the skeletons into the invasion theory in 1947.
George F. Dales: Dales refuted the massacre idea in 1964 in "The Mythical Massacre at Mohenjodaro". He did not propose it.
Climate / Sarasvatī-drying explanation: this is the current view of a slow, many-cause decline (aridity from c. 2200 BCE; Kalibangan and Banawali abandoned). Wheeler's thesis was a sudden, violent, single-cause model.
Harappa vs Mohenjodaro: Wheeler excavated at Harappa (1946), but the "massacre" skeletons came from Mohenjodaro.

Prelims Hooks

R.E.M. Wheeler: Director-General of the ASI from 1944; ex-army brigadier; brought in stratigraphic excavation.
1925: Marshall finds 16 skeletons in "Deadman Lane", Mohenjodaro. 1947: Wheeler links them to an Aryan invasion. 1964: Dales refutes the idea.
"On circumstantial evidence, Indra stands accused": Wheeler, not Marshall or Dales.
Puramdara means "fort-destroyer", a Ṛig Vedic title of Indra. Pur means fort.
"The Mythical Massacre at Mohenjodaro" (1964): author George F. Dales [2].
Trap: Harappan sites show no army and no weapons of war. Invasion is not an accepted cause of decline.

Mains Points

Changing interpretations in history: the move from Wheeler (1947) to Dales (1964) shows how re-examining the same evidence (skeletons from different periods, no destruction layer) can overturn a famous theory. It is a good GS-I example of how sources can be limited and how much depends on how they are read.
The danger of single-cause explanations: Wheeler explained the decline with one dramatic cause, invasion. Scholars now see a slow, many-cause de-urbanisation driven by a climate shift after c. 2200 BCE and the drying of the Sarasvatī. The cities ended, but the people and their cultural practices (the plough, full-arm bangles, the namaste figurine) carried on.
Method as a contribution: Wheeler's lasting legacy is his method, not his theory. Stratigraphic digging made Harappan dates and sequences reliable, and later scholars used that kind of careful evidence to test, and reject, his own invasion claim.
