According to the Book of Mormon, the people commonly referred to as the Amulonites (/ˈæm.jəˈlɑːn.aɪts/) were composed of the priests of king Noah and the daughters of the Lamanites, whom the Amulonites took to wife by force. They are named after Amulon, their leader.
The Amulonites (existing from about 147 BC to about 87 BC) were relatively few but nevertheless acted as a catalyst for war between the Lamanites and Nephites. They worked tirelessly to "stir up the unconverted Lamanites to war against their converted brethren, and then against the Nephites. (Alma 25:2) [1] The Amulonites seem to only be included in the record as an example of what not to do. Without the Amulonites, the Lamanites would not have attacked the Nephites as many times as they did, nor would the people of Ammon or Anti-Nephi-Lehies have left their lands to find a better life.
During the invasion of the Lamanites at the end of the reign of Nephite king Noah, Amulon and the other priests of Noah fled to escape being executed by the people. Being too ashamed to return to the city and "Fearing that the people would slay them", Amulon and his fellow priests did not return to the city of Nephi and left their wives and children in the city.
In the wilderness it appears that the priests had wandered into the Land of Shemlon, where the daughters of Lamanites gathered together to make themselves merry. From a hidden location, the priests "laid and watched them". They waited until there were only a few that gathered to dance, then the priests burst out from where they were hiding and carried off the daughters, which numbered twenty-four.
The Lamanites became convinced that the people of Limhi had stolen their daughters and so went to war against the people of Limhi. But after being driven back the Lamanites, Limhi and Gideon inform the king of the Lamanites that the priests of Noah had fled and that they may be responsible disappearance of their daughters.
