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.

Ironically, little more than a century ago, nothing was known of the Sumerians. The first civilization in history had been lost to history.
