“Brigham Young and the Mormons feel as though the military is about to attack them at any point in time, so they’ve started their own army called the Nauvoo Legion,”
that's in here: https://www.netflix.com/tudum/articles/american-primeval-true-story-explained
the fuckers that created this abortion claim they did a ton of research but the couldn't even bother to read the wikis to get even basic facts correct
the Nauvoo Legion dates to the Charter granted by the State of Illinois in 1841
i have no problem when dipshit fakertainment creators make shit up - but don't lie and say you did research and strove for historical accuracy when your end product looks like the placenta of a mastodon abortion
