  Inventions, discoveries, introductions

• Indus Valley Civilisation, at its peak, covered an area of around 480,000 km². Its heartland lay in the Indus River in Pakistan, but settlements spread as far as the Makran coast, Balochistan, Afghanistan, eastern Punjab, Kutch and Saurashtra. They included cities like Harappa, Mohenjo-daro, Kalibangan, Dholavira, ports like Lothal, Sutkagen-dor and Sokhta Koh and numerous villages as well. They used irrigation to farm and constructed cities. The two main cities had sewage systems, bronze, trade tokens, and hieroglyphs. There were even baths at one of the villages, besides the great baths of brick in each city. Geometry of shrines and altars tends to identify these with the cities of the Yajurveda.
