The fall of 1838 marked the first time the Latter-day Saints engaged in organized retaliation against their enemies. The setting was Northern Missouri and the situation was what is referred to as the “Mormon War.” Here the Saints marched on some nearby settlements that were supporting and equipping their enemies and conducted raids where they pillaged stores and torched buildings. Things only escalated from there and eventually culminated in the infamous “Extermination Order” of Missouri Governor Lilburn W. Boggs, the Hawn’s Mill massacre, the imprisonment of Joseph Smith and other Church leaders in Liberty Jail, and the wholesale removal of Latter-day Saints from the state of Missouri. On this episode of Church History Matters, Casey and I walk through the history of this tumultuous time and think about what the conflict of 1838 might teach us about the justified and unjustified use of violence among Latter-day Saints—and its consequences.
