Brigham Young is one of the most influential figures in the history of the American West. As the prophetic successor to Joseph Smith, Young engineered a westward exodus of tens of thousands of pioneer Latter-day Saints, earning the nickname “American Moses.” His subsequent leadership in Utah evoked both praise and scorn. Young founded 350+ settlements, built the Salt Lake Temple, and testified of Christ. He also said polygamy was a requirement for heaven, taught that Black people were cursed descendants of Cain, and used violent rhetoric that sparked the Mountain Meadows Massacre. In the end, he was a complex man who could inspire both love and fear. This article highlights the life, teachings, and legacy of the “Lion of the Lord.”
