Answer:
The Indus Valley Civilization was unique in its socialist-like society and lack of militarism. The most probable cause for its decline is climate change that caused the Indus River to change its course.
Explanation:
The Indus Valley Civilization was an ancient civilization, part of the River Valley civilizations, which was located along the Indus River on the Indian subcontinent. Unlike the other three River Valley civilizations that shared a lot of similarities, this one was much different and more unique.
The Indus Valley Civilization seems to have a totally peaceful civilization, with any evidence of military or internal conflict lacking. This was probably due to the natural protection that this civilization had from the Himalayas. Also, unlike the big hierarchical differences in the other civilization of the time, in this civilization, everyone seems to have lived in the same conditions, with the same size houses, and it seems that there wasn't class segregation, making it a very socialist-like society. Unfortunately, this civilization collapsed, with the most probable reason being climate change that caused a change in the course of the Indus River, badly affecting the economy and food resources of this civilization.
