The son of King Benjamin, a great prophet and seer, he sends the team that rescues those in the land of Nephi-Lehi (Limhi and his people). When Limhi and his people return to Zarahemla, Mosiah is shown the 24 gold plates that had been found by them and translates them through a Urim and Thummim revealing them to be written by Ether, containing the record of a people called the Jaredites.

Mosiah places Alma in charge of the church and, by law, forbids persecution of believers.

Because all of his sons (Ammon, Aaron, Omner and Himni) refuse to be king (they are too busy being missionaries), Mosiah creates a system of Judges and for the first time the people elect their leaders. Mosiah is therefore the last Nephite king and after him begins the "reign of the judges".
