The Indus River Valley CivilizationLocated in north-western India, the Indus river valley civilization was a collection of villages located along the Indus River that lasted from about 2500 to 1800 BC. The citadel overlooked the lower residential part of the city which had houses placed close together and were fairly large and offered privacy.
