The Mormon Trail is the journey by The Church of Jesus Christ of Latter-day Saints (Mormons) from Illinois to Utah. They wanted to find a place where they could practice their religion freely and live fulfilled lives. One of the key drivers for the migration was persecution from nearby communities. The Mormons, who lived in Nauvoo, Illinois, practiced polygamy, which angered members of the public and leaders who believed in other forms of Christianity. Because of persecution, the Mormons left in groups and settled in different places due to harsh weather conditions. For instance, the first group settled close to the Missouri River because of the harsh winter. As years went by, Mormons devised better ways of travel. Some of the trails that they followed included those in California and Oregon.
