Nehru is not a Hindu.
Please correct this misunderstanding.
His Grandfather Ganghadar Nehru is originally a Muslim by name Ghiyasuddin Ghazi , who tried to escape British slaughtering of Mughal by converting his name to Gangadhar. His last name comes from Nehr ( which means a canal).
NEHRU FAMILY TRUTH
December 30, 2011 by nehrufamily
The Nehru family starts with the Mughal man named Ghiyasuddin Ghazi. He was the City Kotwal i.e. police officer of Delhi prior to the uprising of 1857, under the Mughal rule. After capturing Delhi in 1857, in the year of the mutiny, the British were slaughtering all Mughals everywhere. The British made a thorough search and killed every Mughal so that there were no future claimant to the throne of Delhi. So, the man Ghiyasuddin Ghazi (the word means kafir-killer) adopted a Hindu name Gangadhar Nehru and thus saved his life by the subterfuge. Ghiyasuddin Ghazi apparently used to reside on the bank of a canal (or Nehr) near the Red Fort. Thus, he adopted the name ‘Nehru’ as the family name. The 13th volume of the “Encyclopedia of Indian War of Independence” (ISBN:81-261-3745-9) by M.K. Singh states it elaborately. The Government of India have been hiding this fact.
