Although the Euro-American travelers posed a threat to the Paiutes, it was the arrival of the Mormons in the 1850s that destroyed their sovereignty and traditional lifestyle. The Mormons came to stay, and they settled in places that had traditionally served the Paiutes as foraging and camping areas. As a result, starvation and disease drastically reduced the Paiute population. Between 1854 and 1858 the Mormons conducted a fairly intensive missionary effort among the Paiutes.

I suppose you can’t blame the Mormon settlers too much. They were acting just like all the other Europeans. Just thought it was interesting.
