Ask AI: How did the Indus Valley civilization collapse?

The exact cause of the collapse of the Indus Valley civilization is unclear, as there is no written record from this time period. Scholars generally believe that the civilization experienced gradual decline due to a combination of environmental, economic, and social pressures. These may have included over-exploitation of resources, changes to the climate, or political and social unrest. Additionally, a series of earthquakes or floods is thought to have played a role in the decline. The Indus Valley civilization was eventually replaced by a number of successor cultures, including the Indo-Aryan peoples migrating from Central Asia.
