Guru Gobind Singh
Guru Gobind Singh (1666–1708), born Gobind Das in Patna, became the tenth Sikh Guru in 1675 after his father Guru Tegh Bahadur was beheaded on Aurangzeb's orders.
A warrior, poet and philosopher, he fought twenty-one battles against Mughal armies and the hill rajas of the Sivaliks. On Vaisakhi 1699 at Anandpur he founded the Khalsa, a Sikh warrior community, and introduced the Five Ks.
Two of his sons died in battle and two were executed by the Mughal administrator Wazir Khan. He completed the Guru Granth Sahib and named it the eternal Guru, ending the line of human Gurus before his death in October 1708.
