Answer:
The Indus Valley Civilization was a cultural and political entity which flourished in the northern region of the Indian subcontinent between c. 7000 - c. 600 BCE. Its modern name derives from its location in the valley of the Indus River, but it is also commonly referred to as the Indus-Sarasvati Civilization and the Harrapan Civilization.
These latter designations come from the Sarasvati River mentioned in Vedic sources, which flowed adjacent to the Indus River, and the ancient city of Harappa in the region, the first one found in the modern era. None of these names derive from any ancient texts because, although scholars generally believe the people of this civilization developed a writing system (known as Indus Script or Harappan Script) it has not yet been deciphered.
