Credits to @Jacfsing2 for pointing these Puratan Samprada's out for me.  Khalsa   "Khalsa (Punjabi: "the pure") refers to both a special group of initiated Sikh warriors, as well as the community that considers Sikhism as its faith. The Khalsa tradition was initiated in 1699 by the last living 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, the Sikh new year.
