The greater Indus region was home to the largest of the four ancient urban civilizations of Egypt, Mesopotamia, South Asia and China. It was not discovered until the 1920's. Most of its ruins, even its major cities, remain to be excavated. The ancientIndus Civilization script has not been deciphered.
Many questions about the Indus people who created this highly complex culture remain unanswered, but other aspects of their society can be answered through various types of archaeological studies.
Harappa was a city in the Indus civilization that flourished around 2600 to 1700 BCE in the western part of South Asia. The Harappans used the same size bricks andstandardized weights as were used in other Indus cities such as Mohenjo Daro and Dholavira. These cities were well planned with wide streets, public and private wells, drains, bathing platforms and reservoirs. One of its most well-known structures is the Great Bath of Mohenjo Daro .
There were other highly developed cultures in adjacent regions of Baluchistan, Central Asia and peninsular India. Material culture and the skeletons from the Harappa cemetery and other sites testify to a continual intermingling of communities from both the west and the east. Harappa was settled before what we call the ancient Indus civilization flourished, and it remains a living town today.
