Guru Gobind Singh (; 22 December 1666 – 7 October 1708), born Gobind Rai, was the tenth Sikh Guru, a spiritual master, warrior, poet and philosopher. When his father, Guru Tegh Bahadur, was executed by Aurangzeb, Guru Gobind Singh was formally installed as the leader of the Sikhs at the age of nine, becoming the tenth and final human Sikh Guru. His four biological sons died during his lifetime – two in battle, two executed by the Mughal governor Wazir Kahn.<ref name="Routledge">;<br /></ref> Wikipedia
