Civilization first developed in the Indus River valley in present-day Pakistan in the middle of the 3d millennium B.C., more than a thousand years earlier than it did in China. In fact, the civilization of the Indus valley, usually called Harappan after its chief city, rivals Sumer and Egypt as humanity's oldest. But like Sumer and its successor civilizations in the Middle East, Harappan civilization was unable to survive natural catastrophes and nomadic invasions.
The Indus River Valley Civilization: Mohenjo-Daro and Harappa. The civilization of the Indus River at Mohenjo-Daro and Harappa arose at about 2500 BCE and ended with apparent destruction about 1500 BCE.It is uncertain whether this civilization had its roots in Sumer or Sumer had its roots in this civilization.he cities of Mohenjo-Daro and Harappa were built of fire-baked bricks. Over the centuries the need for wood for brick-making denuded the country side and this may have contributed to the downfall. The written records of this civilization have not yet been deciphered.
