The Mystery of Decline
The Mystery of Decline is a Grade 6 social studies topic in Pengi Social Studies, Chapter 4: Ancient India, exploring the uncertain reasons for the collapse of the Indus Valley Civilization. While earlier theories suggested a violent invasion caused the decline, modern evidence points to natural disasters such as earthquakes or massive floods that altered the course of the Indus River. This environmental disruption likely ruined farming and trade, causing people to gradually abandon cities like Harappa and Mohenjodaro.
Key Concepts
The great Indus cities eventually faded. While historians once believed in a violent invasion, evidence now suggests that natural events , like earthquakes or massive floods, may have changed the course of the Indus River.
This environmental shift would have ruined farming and disrupted trade. People slowly abandoned the cities, leading to the end of this advanced civilization.
