Answer 1

In the 1920s, archaeologists began to excavate the sites of Harappa and Mohenjo-Daro. They uncovered the remains of long-forgotten cities. They had found the Indus Valley civilisation.It was half a century later, in 1912, that more Harappan seals were discovered by J. Fleet, prompting an excavation campaign under Sir John Hubert Marshall in 1921-22 and resulting in the discovery of the civilization at Harappa by Sir John Marshall, Rai Bahadur Daya Ram Sahni and Madho Sarup Vats, and at Mohenjo-daro
