with the Indus Valley Civilisation 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 with the Indus Valley Civilisation. In this view, the Harappan civilisation flourished predominantly on the banks of the Ghaggar-Hakra, not the Indus. For example, Danino notes that his proposed dating of the Vedas to the third millennium BCE coincides with the mature phase of the Indus Valley civilisation, and that it is "tempting" to equate the Indus Valley and Vedic cultures. Romila Thapar points out that an alleged equation of the Indus Valley civilization and the carriers of Vedic culture stays in stark contrast to not only linguistic, but also archeological evidence. She notes that the essential characteristics of Indus valley urbanism, such as planned cities, complex fortifications, elaborate drainage systems, the use of mud and fire bricks, monumental buildings, extensive craft activity, are completely absent in the Rigveda. Similarly the Rigveda lacks a conceptual familiarity with key aspects of organized urban life (e.g. non-kin labour, facets or items of an exchange system or complex weights and measures) and doesn't mention objects found in great numbers at Indus Valley civilization sites like terracotta figurines, sculptural representation of human bodies or seals. Hetalben Sindhav notes that claims of a large number of Ghaggar-Hakra sites are politically motivated and exaggerated. While the Indus remained an active river, the Ghaggar-Hakra dried-up, leaving many sites undisturbed. Sidhav further notes that the Ghaggar-Hakra was a tributary of the Indus, so the proposed Sarasvati nomenclatura is redundant. According to archaeologist Shereen Ratnagar, many Ghaggar-Hakra sites in India are actually those of local cultures; some sites display contact with Harappan civilization, but only a few are fully developed Harappan ones. Moreover, around 90% of the Indus script seals and inscribed objects discovered were found at sites in Pakistan along the Indus river, while other places accounting only for the remaining 10%. Revival In 2015, Reuters reported that "members of the Rashtriya Swayamsevak Sangh believe that proof of the physical existence of the Vedic river would bolster their concept of a golden age of Hindu India, before invasions by Muslims and Christians." The Bharatiya Janata Party Government had therefore ordered archaeologists to search for the river. According to the government of Indian state of Haryana, research
