"killed 80 million Hindus" is an unproven mythical statement that has its origins with Kishori Saran Lal[n. 1] ("K.S. Lal"): who is a former-Indian historian turned pseudo-historian and Hindu fanatic,[n. 2] who is notable for having written several books on the Islamic invasion of India during the middle ages. Indian journels have noted that he is an "historian known for his adherence to the Sangh Parivar brand of history";[1] who themselves are a family of fanatical, extremist and terroristic[n. 3] organisations[n. 4] of radical Hindu origin.[2][3][4][n. 5] As an academic he had claimed to have estimates on the population of India, claiming the Hindu population fell "seventy-five million" after Muslims had conquered it until 1500 CE.[n. 6] Lal's work, however, was found to be highly questionable (he is also known to have worked with other anti-Muslim writers (and pseudo-historians), such as Andrew Bostom).[n. 7] Lal's claims have thus largely been struck down by many Oxbridge historians, such as Simon Digby,[n. 8] Irfan Habib[n. 9][5], and even Hindu historians (such as J. S. Grewal[6]) who note his methods as widely flawed, "wilful"[7] or "frivolous".[6] Digby for instance noted that the "unknown variables" of his work "are so great and the quality of the data yielded" by the sources "so poor that almost any detailed general estimates of population based upon them must appear wilful".[7] Lal's methods have also produced "comically" wrong results on computers.[7][n. 10] Another reviewer for his other work, "The Legacy of Muslim Rule in India", A. A. Powell, notes "[Lal's book] represents not history but propoganda".[8][n. 11] Muslims havingis an unproven mythical statement that has its origins with Kishori Saran Lal("K.S.
