Guru Gobind Singh (Punjabi pronunciation: [gʊɾuː goːbɪn̪d̪ᵊ sɪ́ŋgᵊ]; born Gobind Das; 22 December 1666 – 7 October 1708) was the tenth and last human Sikh Guru. He was a warrior, poet, and philosopher. In 1675, at the age of nine, he was formally made the leader of the Sikhs after his father Guru Tegh Bahadur—the ninth Sikh Guru—was executed by the emperor Aurangzeb. His four biological sons died during his lifetime—two in battle and two executed by the Mughal administrator Wazir Khan.
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 holy religious scripture and the eternal Guru. He also established the concept of Guru Panth as his spiritual successor, however this manner of guruship is seldom evoked today.
