Indus Valley civilizations collapse (jan 1, 2000 BC – jan 1, 1900 BC)
Description:
The architecture in the Indus Valley was the first to decline, with a lack of quality and attention. Also, populations seemed to decline, maybe due to river changes. A last theory is the decline was due to an Aryan invasion.
