Book of Mormon. He was a king over the Lamanites, a position he inherited from his father, Ammoron. Within a few years after the defeat and death of his father at the hands of the Nephites, Tubaloth began to stir his people up against the Nephites again in the 41st year of the reign of judges. He appointed Coriantumr over his armies and sent them to battle against the Nephites in the land of Zarahemla. While the armies met with some initial success, they were subsequently defeated and Coriantumr was killed in battle.
