A religious group trekked across the Great Plains looking for a haven, where they could practice their faith from 1846 onwards. They established themselves in Utah, and received regular fresh influxes of co-religionists thereafter. They have a share in creating the hostility that marked relations between Indian tribes and Whites in the second half of the Nineteenth Century. What was the name of the sect?

White Americans had settled both the Atlantic and the Pacific coasts, but the Great Plains in between had been hardly incorporated into the USA. Native Americans (Red Indians) occupied them, and the potential for conflict loomed seriously, as White Americans were more and more tempted to encroach on Indian lands.
