Khalsa refers to both a community that considers Sikhism as its faith, as well as a special group of initiated Sikhs. The Khalsa tradition was initiated in 1699 by the Tenth Guru of Sikhism, Guru Gobind Singh. Its formation was a key event in the history of Sikhism. The founding of Khalsa is celebrated by Sikhs during the festival of Vaisakhi.
