History
The Indus Valley Civilisation
The Indus Valley Civilisation was a Bronze Age urban culture that flourished across present-day Pakistan and north-west India from about 2600 to 1900 BCE, with its two largest known cities, Mohenjo-daro in Sindh and Harappa in Punjab, both in Pakistan. Its script, found on thousands of seals, remains undeciphered.

Background
Excavations from the 1920s onward revealed planned street grids, standardised fired bricks, covered drains and large public structures such as the Great Bath at Mohenjo-daro. The civilisation traded with Mesopotamia, used a uniform system of weights, and declined gradually after about 1900 BCE, probably through a combination of river shifts and climate change rather than a single event.
