Purushottam Nagesh Oak (2 March 1917 ' 4 December 2007), commonly referred to as P. N. Oak, was an Indian writer, notable for his Hindu-centric brand of historical revisionism. Oak's "Institute for Rewriting Indian History" issued a quarterly periodical called Itihas Patrika in the 1980s.
Oak's claims, e.g. that Christianity and Islam are both derivatives of Hinduism, or that the Catholic Vatican, Kaaba and the Taj Mahal were once Hindutemples to Shiva,[1] and their reception in Indian popular culture have been noted by observers of contemporary Indian society, who variously characterized Oak as a "mythistorian"[2] or more directly as a "crackpot".[3] In his book, Some Missing Chapters of World History, Oak claimed that the first civilization was developed in India from which all world civilizations grew. He wrote books in three languages.
