Answer 1

The Harappa site was first briefly excavated by Sir Alexander Cunningham in 1872-73, two decades after brick robbers carried off the visible remains of the city. He found an Indus seal of unknown origin. The first extensive excavations at Harappa were started by Rai Bahadur Daya Ram Sahni in 1920.

Answer:

Sir John Hubert Marshall led an excavation campaign in 1921-1922, during which he discovered the ruins of the city of Harappa. By 1931, the Mohenjo-daro site had been mostly excavated by Marshall and Sir Mortimer Wheeler. By 1999, over 1,056 cities and settlements of the Indus Civilization were located.
