History: comparison of civic administration of Indus vally civilization with the present times
Answers
Answer:
The IVC declined around 1800 BCE but the actual reasons behind its demise are still debated.
One theory claims that Indo-European tribe i.e. Aryans invaded and conquered the IVC.
In later cultures various elements of the IVC are found which suggest that civilization did not disappear suddenly due to an invasion.
On the other hand, many scholars believe natural factors are behind the decline of the IVC.
The natural factors could be geological and climatic.
It is believed that the Indus Valley region experienced several tectonic disturbances which causes earthquakes. Which also changed courses of rivers or dried them up.
Another natural reason might be changes in patterns of rainfall.
There could be also dramatic shifts in the river courses, which might have brought floods to the food producing areas.
Due to combination of these natural causes there was a slow but inevitable collapse of IVC.
