c. 2410 BC: By this time, kings in Sumer have ceased to be automatically high priests of the city deity. (Roux 1980) Semitic infiltration and conquest of Mesopotamia begins. (1968 RD Almanac)
Harappan civilisation, at its peak, covered an area of around 480,000 km² (298 258.172 mi²). Its heartland lay in the Indus Valley 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 (early coins), 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: they might easily be a thousand years older than this conservative date.
