The Indus Valley Civilisation is sometimes called the "Sarasvati culture", "Sarasvati Civilization", "Indus Ghaggar-Hakra civilisation," "Indus-Sarasvati Civilization," or "Sindhu-Sarasvati Civilization" by Hindutva revisionists, referring to the Sarasvati river mentioned in the Vedas, and equating the Vedic culture.
