The Lamanites are one of the people described in the Book of Mormon, a religious text published in 1830 by Joseph Smith, founder of the Latter Day Saint movement. The Book of Mormon portrays the Lamanites as usually dark-skinned, wicked rivals to the usually lighter-skinned, righteous Nephites, both of whom are portrayed as descendants of Israelites who traveled to the New World by boat circa 600 BC. (Other groups from the book include the Jaredites, and Mulekites.) Historically, Mormons have identified the Lamanites as the indigenous peoples of the Americas and the Polynesians, or some part of their ancestors. However, in the 21st century, Mormon scholars who favor a limited geography model have been disclaiming any significant genetic connection between Lamanites and any modern people. Because only Mormons consider the Book of Mormon to have an ancient historical basis, Lamanites are not considered to be a valid category of people by mainstream scholars.
