Nanakpanthi
A Nanakpanthi is a follower of the teachings of Guru Nanak, the first guru of Sikhism. The community transcends the boundaries of Sikhism and Hinduism, and was also a reference to the early Sikh community. Most Sindhi Hindu people are Nanakpanthi, and during the 1881 and 1891 censuses, the community could not decide whether to self-identify as Hindu or Sikh. In 1911, Shahpur District ( Punjab) reported 12,539 Hindus (20% of the total Hindu population) identifying themselves as Nanakpanthi, in addition to 9,016 Sikhs (22% of the total Sikh population).
The Nanakpanthi community spread far beyond Punjab and Sindh. Maghar, a town in Uttar Pradesh has a high proportion of the Nanakpanthi community.
