According to the Book of Mormon, the Anti-Nephi-Lehies (/ˈæntaɪ ˈniːfaɪ ˈliːhaɪz/) were an ethnic group of Lamanites formed around 90 BC, after a significant religious conversion. They made a covenant that they would not participate in war, and buried their weapons. Eventually they changed their name to the people of Ammon, or Ammonites. During a later period of warfare, the young men of the group who had not made the pacifist covenant became a military unit known as the two thousand stripling warriors, and were protected by divine intervention.
