Hi Friend

Here is ur answer

Archaeologists believe that Indus Valley Civilisation declined due to several possibilities. One theory is that natural calamities like flood, earthquakes or fire destroyed the civilisation. Another is that changes in the course of the river Indus left the cities without a source of water nearby forcing them to move. The third reason cited is environmental change caused by deforestation. Another likely cause is that foreign invaders came from outside and destroyed the civilisation. By 1,500 BCE the Indus Valley regions were taken over by the Aryans and that was the beginning of a new period of history.

Hope it's helpful to you
