The earliest excavations in the Indus valley were done at Harappa in the West Punjab and Mohenjodaro in Sind. Both places are now in Pakistan. The findings in these two cities brought to light a civilization. It was first called the ‘The Indus Valley Civilization’. But this civilization was later named as the ‘Indus Civilization’ due to the discovery of more and more sites far away from the Indus valley. Also, it has come to be called the ‘Harappan Civilization’ after the name of its first discovered site.

Important Sites

Among the many other sites excavated, the most important are Kot Diji in Sind, Kalibangan in Rajasthan, Rupar in the Punjab, Banawali in Haryana, Lothal, Surkotada and Dholavira, all the three in Gujarat. The larger cities are approximately a hundred hectares in size. Mohenjodara is the largest of all the Indus cities and it is estimated to have spread over an area of 200 hectares.

Origin and Evolution

The archaeological findings excavated for the last eight decades reveal the gradual development of the Harappan culture. There are four important stages or phases of evolution and they are named as

1. pre-Harappan
2. early-Harappan
3. mature-Harappan
4. late Harappan

The pre-Harappan stage is located in eastern Baluchistan. The excavations at Mehrgarh 150 miles to the northwest of Mohenjodaro reveal the existence of pre-Harappan culture. In this stage, the nomadic people began to lead a settled agricultural life.
