Urban culture was developed, and international trade as well. It was a mixed people, not just one race.
Harapa's art is represented by architecture, sculpture, stamps, jewelry and clothing. The architecture does not show grand temples or palaces, but large, comfortable houses built on wide streets. The biggest construction is the reservoirs and baths, and it is unknown to what extent they would be linked to a sacred aspect. The clothes were sophisticated, as shown by the various stamps used in maritime trade with other countries.
They worshiped the Mother Goddess (Sakti).
