mystery of Indus valley civilization

mystery of India valley civilization . When was the Indus Valley Civilisation?

The Indus Valley Civilisation was a Bronze Age society that existed at the same time as Ancient Egypt and Mesopotamia.

The peak of the Indus civilisation, which saw the building works and manufacturing mentioned above happened between 2600 and 1900 BCE, after which it began to decline. Where was the Indus Valley Civilisation?
The Indus Valley Civilisation takes its name from the Indus River because many settlements were built along its banks.

Harappa and Mohenjo-daro are the two most famous cities and have been studied in depth by archaeologists.

Other major cities include Rakhigarhi, Ganweriwala and Dholavira.

Many of the sites existed along the Indus river and the now extinct Sarasvati river.

At its height, the full extent of the Indus civilisation is estimated to be around 3 million km2, which is bigger than both Ancient Egypt and Ancient Mesopotamia combined.

What was the collapse of the Indus Valley civilisation?

Around 1900 BCE, things in the Indus Valley began to change. Many of the things that had previously been shared across the Indus Valley such as the unified system of weights and measures and planned cities with large populations began to fall out of use.

Early archaeologists like Mortimer Wheeler interpreted this change as a sudden collapse. Archaeologists today think the evidence points towards a more gradual change.
