According to the Book of Mormon, Alma (/ˈælmə/) was a Nephite prophet who established the Church of Jesus Christ in the Americas during the reign of the wicked King Noah. One of the Book of Mormon's greatest figures, he is sometimes referred to as "Alma the Elder" as seen on the website of The Church of Jesus Christ of Latter-day Saints to avoid confusion with his son, also named Alma, who is often called "Alma the Younger." It is believed that he was born in roughly 174 BC. and his son Alma the Younger was born in roughly 126 BC.
While a young man, Alma was one of several corrupt priests who served King Noah in the land of Nephi. About 148 BC, a prophet named Abinadi was arrested for preaching repentance and condemning the wickedness of Noah and his people. Brought before the king and his priests, Abinadi emphatically urged them to repent and obey the gospel of Jesus Christ. Of all who heard him, only Alma was touched by Abinadi's words. When Alma began to defend Abinadi the king had Alma cast out and Abinadi burned alive. Fleeing for his life, Alma went into hiding and wrote down what Abinadi had said before the court. Alma began to preach the gospel in secret, emphasizing Abinadi's teachings "concerning that which was to come, and also concerning the resurrection of the dead, and the redemption of the people, which was to be brought to pass through the power, and sufferings, and death of Christ, and his resurrection and ascension into heaven" ().
At a hidden retreat in the wilderness called the waters of Mormon, Alma baptized his listeners and organized the church of Christ among them. In time, King Noah found out where Alma's congregation was meeting, and, fearing insurrection, sent his army to destroy them. Being warned by God of the army's coming, Alma quickly led his band of approximately 450 converts into the wilderness for eight days, finally stopping in an uninhabited land which they named Helam. The people of Alma established the city of Helam there and prospered for many years, remaining faithful to God's commandments.
