What do historians think happened to the Harappans?

Answer 1

Historians believe that the Harappan civilization, also known as the Indus Valley Civilization, declined due to a combination of factors, including climate change, shifts in river patterns, and possibly increased aridity that affected agriculture. Some theories suggest that invasions or migrations by Indo-Aryan groups may have contributed to their decline, although evidence for this is debated. Additionally, social and economic factors, such as trade disruptions, could have played a role in their eventual collapse. Overall, the exact reasons remain uncertain, and ongoing archaeological research continues to provide new insights.
