Ancient History of India Discovery 

In 1921, at the time of the construction of a railway from Lahore to Karachi, a British archaeologist named John Marshall and several Indian partners dug into the old Indus route (in the area that now belongs to Pakistan) and discovered one of the most amazing archaeological discoveries of the last century: two ancient cities, identical in form, 500 kilometers from each other, dating to about 2500 years BC. The discovery completely changed the face of India’s ancient history.
