Guru Gobind Singh, Indian 10th Sikh guru (b. 1666)
Guru Gobind Singh (Punjabi pronunciation: [gʊɾuː goːbɪn̯d̯ᵊ sɪ́ŋgᵊ]; 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.Among his notable contributions to Sikhism are founding the Sikh warrior community called Khalsa in 1699 and introducing the Five Ks, the five articles of faith that Khalsa Sikhs wear at all times. Guru Gobind Singh is credited with the Dasam Granth whose hymns are a sacred part of Sikh prayers and Khalsa rituals. He is also credited as the one who finalized and enshrined the Guru Granth Sahib as Sikhism's primary scripture and eternal Guru.
