History of Pakistan
2600 BC Indus river Valley Civilisation started in Kot Diji, Mohenjo-daro and Harappa areas. The Indus Valley Civilization flourished from about 2600 BCE to 1900 BCE. It marked the beginning of the urban civilization on the subcontinent. It was centred on the Indus River and its tributaries, which is in present-day Pakistan. It is thought that a gradual deforestation caused by geological disturbances and climate change caused the fall of the civilization. The civilization is famous for its cities that were built of brick, had a road-side drainage system and multi-storied houses
