Origin 1699
Also called the Khalsa Panth, and rendered in English as the Order of the Pure. The order of initiated Sikhs, founded by Guru Gobind Singh at Anandpur at Vaisakhi in 1699. Khalsa means the pure, and also, in the revenue usage of the period, land held directly of the sovereign rather than through an intermediary, a sense the founding deliberately invokes, since the Khalsa belongs to the Guru directly and to no one in between.
Its members are initiated by amrit, wear the five articles of faith, keep the daily Nitnem, and abstain from the four grave breaches. Men take the name Singh, lion, and women Kaur, princess, which removed at a stroke the family names by which caste was read.
What was created was a body that was simultaneously a religious order, a community and an army, and the tradition does not separate those. It gave institutional form to miri and piri, and it was founded under military pressure in a period when the Sikh community was being killed for existing.
Its constitution is unusual and was designed to be. Guru Gobind Singh initiated the first five and then asked them to initiate him, placing himself under the order he had made; the authority of the Khalsa therefore rests in the body of initiated Sikhs rather than in any person, and any five acting as the Panj Pyare carry it. Nine years later he ended the human guruship altogether. The formula in which the Khalsa understands itself, that the Khalsa belongs to the timeless one and the victory belongs to the timeless one, is a denial that it belongs to anyone at all.
Not every Sikh is of the Khalsa, and Sikh teaching does not hold that initiation is required for liberation, which comes through the Name. The relation between the initiated order and the wider community of Sikhs has been the tradition's most persistent internal question, and the categories Amritdhari, Keshdhari, Sahajdhari and Patit are the vocabulary in which it is argued.
