"The Sikh Gurus Tegh Bahadur, beheaded by Aurangzeb in 1675 for refusing to convert, and his son Govind Singh, who founded the military Khalsa order and whose four sons were killed by the Moghul troops, are very popular in Hindutva glorifications of national heroes'. Their pictures are routinely displayed at functions of the RSS and its affiliates, and their holidays celebrated, e.g.: 'Over 650 branches of Bharat Vikas Parishad observe Guru Tegh Bahadur Martyrdom Day'. Tegh Bahadur’s martyrdom in 1675 was of course in the service of Hinduism, in that it was an act of opposing Aurangzeb’s policy of forcible conversion. An arrest warrant against him had been issued on non-religious and nonpolitical charges, and he was found out after having gone into hiding; Aurangzeb gave him a chance to escape his punishment by converting to Islam. Being a devout Muslim, Aurangzeb calculated that the conversion of this Hindu sect leader would encourage his followers to convert along with him. The Guru was tortured and beheaded when he refused the offer to accept Islam, and one of his companions was sawed in two for having said that Islam should be destroyed.... He was not a Sikh defending Hinduism, but a Hindu of the Nanakpanth defending his own Hindu religion..."
