The Land of Morianton was a region situated on the coastal borders near the Land of Lehi, as described in the Book of Mormon narrative during the reign of the judges. Named possibly after its prominent leader Morianton, this area became a point of contention due to a land dispute with its neighboring inhabitants from the Land of Lehi (Alma 50:25). As tensions escalated over this territorial disagreement, the involvement of Captain Moroni, the Nephite military leader, became necessary when the people of Lehi sought his assistance to prevent an imminent attack.
Subsequently fearing the approach of Moroni’s forces, Morianton endeavored to relocate his people northward. However, this effort was halted through military intervention, and peace was restored in the area following a covenant agreed upon by Morianton’s people (Alma 50:35-36). Despite this resolution, stability was short-lived; within a year, the Lamanites overran the region, displacing its inhabitants who merged with other displaced groups (Alma 51:26; 59:5).
The city of Morianton itself eventually fell under Lamanite control and was heavily fortified against future incursions (Alma 55:33). Captain Moroni planned a campaign to reclaim the city in 63 B.C., though specific details about the outcome of this effort are not detailed in the scriptural record.
