Guru Gobind Singh Ji (January 5, 16671 - 21 October 1708), born "Gobind Rai" at Patna Sahib, Bihar, India, was the tenth and last of the human form Gurus of Sikhism. He became Guru on November 24, 1675, at the age of nine, following the martyrdom of his father, the ninth Guru, Guru Tegh Bahadur Ji.
A divine messenger, a warrior, a poet, and a philosopher, Guru Gobind Singh Ji molded the Sikh religion into its present shape, with the institution of the Khalsa fraternity, and the completion of the sacred scripture, the Guru Granth Sahib Ji, in the final form that we find today. Before leaving his mortal body in 1708, Guru Gobind Singh decreed the Guru Granth Sahib Ji as the next and perpetual Guru of the Sikhs.
