The Bronze Age in India started around 2500 BC. Around this time, small villages grew out to large cities, forming the so-called Indus Valley Civilization. The cities of the Indus Valley are in many ways different from those of Mesopotamia. In its main cities, Harappa and Mohenjodaro, we find no elaborate palaces or temples nor do we find any references to important leaders. However, we do find beautiful baths, lined with bitumen and surrounded by colonnades.
