Guru Gobind Singh Ji started the "Khalsa" tradition after his father, Guru Tegh Bahadur Ji, was beheaded during the Islamic sharia rule of the Mughal Emperor Aurangzeb. Guru Gobind Singh Ji created and initiated the Khalsa as a warrior with a duty to protect the innocent from any form of religious persecution. The founding of the "Khalsa" started a new phase in the Sikh tradition. It formulated an initiation ceremony ("amrit pahul", nectar ceremony) and rules of conduct for the "Khalsa" warriors. It created a new institution for the temporal leadership of the Sikhs, replacing the earlier "masand" system. Additionally, the "Khalsa" provided a political and religious vision for the Sikh community.
