<P> The Indus Valley Civilisation is also named the Harappan civilisation after Harappa , the first of its sites to be excavated in the 1920s , in what was then the Punjab province of British India . The discovery of Harappa , and soon afterwards Mohenjo - daro , was the culmination of work beginning in 1861 with the founding of the Archaeological Survey of India in the British Raj . Excavation of Harappan sites has been ongoing since 1920 , with important breakthroughs occurring as recently as 1999 . This Harappan civilisation is sometimes called the Mature Harappan culture to distinguish it from the cultures immediately preceding and following it . Of these , the earlier is often called the Early Harappan culture , while the later one may be referred to as the Late Harappan , both of which existed in the same area as the Mature Harappan Civilisation . The early Harappan cultures were preceded by local Neolithic agricultural villages , from which the river plains were populated . A total of 1,022 cities and settlements had been found by 2008 , mainly in the general region of the Indus and Ghaggar - Hakra Rivers , and their tributaries ; of which 406 sites are in Pakistan and 616 sites in India ; of these 96 have been excavated . Among the settlements were the major urban centres of Harappa , Mohenjo - daro ( UNESCO World Heritage Site ) , Dholavira , Ganeriwala and Rakhigarhi . </P>
