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 Valley civilization was an ancient civilization in the Indian subcontinent. It was discovered by archaeologists in the 1920s. It developed along the Indus River and the Ghaggar-Hakra River, in the area of modern Pakistan and north-west India and Afghanistan. It started during the Bronze Age.
