The Mormon Trail or Mormon Pioneer Trail is the 1,300-mile (2,092 km) route that members of The Church of Jesus Christ of Latter-day Saints traveled from 1846 to 1868. Today, the Mormon Trail is a part of the United States National Trails System, known as the Mormon Pioneer National Historic Trail. During the first few years, the emigrants were mostly former occupants of Nauvoo who were following Young to Utah. Later, the emigrants increasingly comprised converts from the British Isles and Europe.
