Where do Sikhs come from?

The Sikh faith was founded by Guru Nanak in 1469 in Punjab. Punjab is located in South Asia and is currently divided between India and Pakistan. Although most Sikhs have their roots in South Asia, and Punjab specifically, there are Sikhs of diverse backgrounds and nationalities. It should be noted that Guru Nanak himself travelled across the world from China to the Middle East teaching his message of the universality of One God and the unity of humanity.
