The Book of Helaman (/ˈhiːləmən/HEE-lə-mən) is one of the books that make up the Book of Mormon, a text held sacred by churches within the Latter Day Saint movement, including the Church of Jesus Christ of Latter-day Saints (LDS Church). The book continues the history of the Nephites and the Lamanites from approximately 50 BC to 1 BC. It discusses political unrest among the Nephites and the formation of a group of secret dissenters called the Gadianton Robbers. Helaman, son of Helaman leads the Nephites for a time, and his sons Nephi and Lehi go on a successful mission to the Lamanites. When Nephi returns home, he correctly identifies the murderer of the chief judge using his prophetic powers, and sends a famine to the Nephite which lasts three years. After a digression from Mormon, the book of Helaman ends with Samuel the Lamanite's prophecy of the signs that will precede Christ's birth and death. Helaman deals with themes of external and internal conflict, hidden information, Nephite racism, and Mormon's views of history as deduced by his redaction of it.
