Sikh sects, denominations, traditions, movements, sub-traditions, also known as sampardai (Gurmukhi: ਸੰਪਰਦਾ; saparadā) in the Punjabi language, are sub-traditions within Sikhism that with different approaches to practicing the religion. Sampradas believe in one God, typically rejecting both idol worship and castes. Different interpretations have emerged over time, some of which have a living teacher as the leader.[1][2] The major traditions in Sikhism, says Harjot Oberoi, have included Udasi, Nirmala, Nanakpanthi, Khalsa, Sahajdhari, Namdhari Kuka, Nirankari, and Sarvaria.[3][4]
During the persecution of Sikhs by Mughals, several splinter groups emerged, such as the Minas and Ramraiyas,[5] during the period between the death of Guru Har Krishan and the establishment of Guru Tegh Bahadur as the ninth Sikh Guru. These sects have had considerable differences. Some of these sects were financially and administratively supported by the Mughal Empire in the hopes of gaining a more favorable and compliant citizenry.[2][5]
In the 19th century, Namdharis and Nirankaris sects were formed in Sikhism, seeking to reform and return the Sikh faith to its "original ideology".[6][7][8] They also accepted the concept of living gurus. The Nirankari sect, though unorthodox, was influential in shaping the views of Khalsa and the contemporary-era Sikh beliefs and practices.[9][10] Another significant Sikh break-off sect of the 19th century was the Radha Soami movement in Agra led by Shiv Dayal Singh, who relocated it to Punjab.[11] Other contemporary-era Sikhs sects include 3HO Sikhism, also referred to as Sikh Dharma Brotherhood, formed in 1971 as the Sikh faith in the western hemisphere; Yogi Bhajan led this.[11][12][13] See also Dera (organization) (non-Sikh Deras) for more examples of Sikh sects.

"Sikhism consists of three major denominations; these sects in the order of importance are: Khālsā, Nāmdhari, Nirankāri. They take different positions on the nature of the Guru or spiritual teacher. Khālsā sect - to which the majority of Sikhs adhere - itself consists of three groups, which become distinguished from each other by their certain kind of clothes, lifestyle, and some religious principles. These three groups are called Nihang (Akāli), Nirmalā, and Sewāpanthi. Furthermore, in some scriptures, references have been made to one of the Sikh sects called Udāsi, which was established by Guru Nanak's oldest son, Sri Chand. Considering the beliefs and religious ceremonies, this sect is not similar to mainstream Sikhism because it neither acknowledges the series of ten Gurus nor is monotheistic. Nevertheless, since Udāsi identifies itself as the follower of Guru Nanak and has played an important role in Sikh history, it would be regarded as one of the Sikh sects in this paper."
