What year was the Mormon trail start?
The Mormon Trail started in February 1846.
The Mormon Trail was traveled by Mormon Pioneers from Illinois to Utah after they had been kicked out of Illinois. It was then traveled by Mormon converts from Europe and Canada as they immigrated to "Zion" (the Mormon settlements in Utah). The trail was mostly discontinued after the railroad reached Salt Lake City.
The Mormon Trail and the Oregon Trail followed nearly the same route until the Mormon trail turned down toward Utah in modern day Wyoming. The original group of Mormon pioneers, already having the Great Basin/Rocky Mountain area in mind, forged the trail under the direction of Brigham Young in 1846/47. Subsequent groups of pioneers traveled the trail each year under the direction of various trail bosses until 1870, when it became more practical to travel…
Brigham Young lead the first group of Mormon pioneers along the Mormon Trail to Utah in 1846-47. Subsequent groups came over the next 25 years lead by various experienced trail guides. The Mormon Trail followed a similar route to the Oregon Trail until Wyoming, when it went south to Utah rather than north to Oregon.
