Lamanite

According to the Book of Mormon, a Lamanite ( /ˈleɪ.mʌn.aɪt/) is a member of a dark-skinned nation of indigenous Americans that battled with the light-skinned Nephite nation. Mainstream archaeologists, geneticists, and historians do not recognize the existence of Lamanites but adherents of the Latter Day Saint movement typically believe that the Lamanites comprise some part, if not the entirety, of the indigenous peoples of the Americas and the Polynesian people.

The Book of Mormon describes the Lamanites as descendants of Laman and Lemuel, two rebellious brothers of a family of Israelites who crossed the ocean in a boat around 600 BC. Their brother Nephi founded the Nephite nation. The Lamanites reputedly gained their dark skin as a sign of the curse for their rebelliousness (the curse was the withdrawal of the Spirit of God), and warred with the Nephites over a period of centuries. The book says that Jesus appeared and converted all the Lamanites to Christianity; however, after about two centuries, the Lamanites fell away and eventually exterminated all the Nephites. By the end of the Book of Mormon, the Lamanites were defined less by their skin color than by their lack of Christianity. Many Mormons believe that the Polynesian people originated from the descendents of Hagoth who led his people off on a ship and was never heard from again. Although Hagoth was a Nephite, these Mormons regard Polynesians as Lamanites.

Within the culture of Mormonism, indigenous Americans and Polynesians are sometimes referred to as "Lamanites".
