How long was the Mormons journey west?
The first Mormon Pioneers left Illinois in 1846 and arrived in Salt Lake City in 1847 after wintering over in Nebraska. Mormon converts from all over the world continued to immigrate to Salt Lake City on the Mormon trail until 1869, when the transcontinental railroad was completed. Most converts then made the journey by rail.
After being driven from Ohio, Missouri, and Illinois, the Mormons were forced to begin a journey, or quest, across the United States to seek religious freedom. In 1846, the first companies began the trek west, by ox-drawn wagons and handcarts. Many died on this first and many subsequent journeys. The Mormons finally settled in the Salt Lake Valley, where religious freedom was reached.
The Mormons moved west in search of a new home, not a new phone. Phones weren't even invented yet (this was in the 1840's). The Mormons had been persecuted and kicked out of Ohio, Missouri, and Illinois, so they went further west into what was then Mexico in search of a place where they could live in peace.
