Hinduism was just terminology invented to classified all the
religious practices in the Indian sub-continent that was different from
Who Invented the term "Hinduism"?
Over the past decade, many scholars have put forward the claim that Hinduism was constructed, invented, or imagined by British scholars and colonial administrators in the nineteenth century and did not exist, in any meaningful sense, before this date. 1 Prominent among scholars who have made this constructionist argument, if I can call it that, are Vasudha Dalmia, Robert Frykenberg, Christopher Fuller, John Hawley, Gerald Larson, Harjot Oberoi, Brian Smith, and Heinrich von Stietencron. 2 W. C. Smith is sometimes identified, quite correctly, as a noteworthy precursor of these scholars. 3 Romila Thapar (1985; 1989, 1996) and Dermot Killingley (1993:61–64) have offered somewhat similar arguments, but both display greater sensitivity to historical ambiguities, distributing the construction of a distinctly modern Hinduism among British orientalists and missionaries and indigenous nationalists and communalists. Carl Ernst (1992:22–29, n.b. 23) discusses early Muslim references to “Hindus” and their religion, but he joins the above scholars in claiming that the terms “do not correspond to any indigenous Indian concept, either of geography or religion.” J. Laine (1983) agrees with Smith and his modern epigones that Hinduism was invented in the nineteenth century, but credits the invention to the Indians rather than to the British.
Hence it have nothing to do with the religions nor the nationalities.
