The Indus Valley Civilization (IVC) was a Bronze Age civilization (33001300 BCE; mature period 26001900 BCE) that was located in the northwestern region of the Indian Subcontinent. Flourishing around the Indus River basin, the civilization primarily centered along the Indus and the Punjab region, extending into the Ghaggar-Hakra River valley and the Ganges-Yamuna Doab. Geographically, the civilization was spread over an area of some 1,260,000 km, making it the largest ancient civilization in the world. There is an Indus Valley site on the Oxus river at Shortugai and extending towards Alamgirpur on the Hindon river located only 28 km from Delhi, India.
