The reason why the Indus Valley Civilization vanished is still unknown. Not many artefacts have been found to let us gain insight into their culture. Their writing was also mostly in Sanskrit, which no one can translate in this day and age.
Harrapa is the only one city of Indus Valley Civilization so it should not be considered or called Harrapan Civilizations ..... Indus Valley Civilization has around 1500 discovered sites ... so please keep naming it INDUS VALLEY CIVILIZATION... thanks
The problem is not that less is known about the Indus River Valley civilization; the real problem is that much of what we are told by academics about this culture is untrue. We are told that horses, Sanskrit and wheels did not exist in India/Pakistan during Indus valley times, but the truth is that every level of Harappa (and many other IVC sites) have yielded bones of true horses (Equus caballus) verified by the biologist Sandor Bokonyi. Toy oxcarts with wheels have been found at several IVC sites. As for Sanskrit and Prakrit, Indus seals deciphered as long ago as 2010 have been found to encode such common Sanskrit names as Ravi, Mani, Aprian, and so forth. See the Indus Script Dictionary page on Facebook for more details.
The Indus Valley script, known as the Harappan script, is yet to be deciphered, so it is unknown if it contained an "A" character.
The British wanted to add Indus valley to their empire for two main reasons:-The region was fertile and populated, so there were profits to be made.If they controlled Indus valley, they could easily block any further Russian advance into Afghanistan.They conquered Indus valley in 1838
The Indus River Valley Civilization is a Theocracy government and a Theocracy is run by a priest so there government and religion were combined.
The Indus valley people left because the were having lots of invasion, they left their home so in 1500 BC they were forgotten.
The cities in the Indus Valley were very clean because of the meticulous way they were built in. The city's sanitation and waste water technologies had substantially developed.
