Evidence of an ‘invasion’-Theories propounded by scholars.
John Marshall (Mohenjodaro and the Indus Civilization, 1931)
John Marshall presented the evidence of a massacre in Mohenjodaro in 1925.
Skeletons of people with ornaments were found at the site, this indicates that the Harappan civilization was destroyed by foreign invasion.
R.E.M Wheeler (Harappa 1946, Ancient India, 1947)
In 1947, R.E.M Wheeler, then Director–General of the ASI, tried to correlate this archaeological evidence with Rigveda. The Rigveda mentions pur, meaning rampart, fort, or stronghold. Indra, the Aryan war-god is called puramdara, the fort destroyer.
It is assumed that as wheeler put it,”Indra stands accused’’ of destroying the cities of the Harappan civilization and of the responsibility for the massacre at Mohenjodaro.
G.F Dales (The Mythical Massacre at Mohenjodaro, Expedition, 1964)
In the 1960s, this theory was opposed by an archaeologist named George Dales.
He demonstrated that the skeletons found at the site did not belong to the same period.
There is no sign of extensive burning, no bodies of warriors clad in armour and surrounded by weapons war.
