Relationship between Indus valley civilization and other valley civilization

The Indus Valley Civilization (IVC) is considered one of the three cradles of early civilization in the Eastern Hemisphere, alongside Ancient Egypt and Mesopotamia. All three of these civilizations flourished during the Bronze Age--a time characterized by bronze craftsmanship and early urban development (falling chronologically after the Stone Age and before the Iron Age).

The Indus Valley Civilization (IVC) is considered one of the three cradles of early civilization in the Eastern Hemisphere, alongside Ancient Egypt and Mesopotamia. All three of these civilizations flourished during the Bronze Age--a time characterized by bronze craftsmanship and early urban development (falling chronologically after the Stone Age and before the Iron Age). 

All three of these early civilizations were settled around a major river, and relied on the relatively lush fertility of their river valleys to provide the resources needed to build complex urban development. Hence, all three are sometimes referred to as "River Valley Civilizations."

Despite the relative lack of knowledge surrounding the IVC (mostly due to our inability to decipher the Harappan language), there are certain characteristics we know that set it apart from other river valley civilizations. Primarily, it was the largest, with a population of over five million at its peak. The IVC geographically lay in the basin of the Indus River, stretching from Afghanistan through Pakistan to northern India. Unlike Egyptian and Mesopotamian archaeology, there is very little evidence to suggest that IVC life was dominated by war, and a lot of evidence to characterize the IVC as peaceful, prosperous, and widespread.
