What were the reasons for the decline and disappearance of the Indus valley civilization?

The decline and disappearance of the Indus Valley civilization, which flourished around 2600-1900 BCE, is a subject of ongoing debate among scholars. Several theories have been proposed to explain its downfall. One key factor is believed to be environmental changes such as tectonic activity, leading to the shifting of river courses that disrupted the agricultural system of the civilization. The deterioration of the monsoon patterns and excessive flooding might have also contributed to the decline. Additionally, internal factors like social and political unrest, economic disparity, or invasion by nomadic tribes have been suggested. However, the lack of substantial evidence and the complexity of the civilization make it challenging to establish a definitive reason for its disappearance. Further archaeological excavations and research are required to unravel the mysteries surrounding the decline of the Indus Valley civilization.
