After being severely persecuted and forcibly ejected from New York, then Ohio, then Missouri and then Illinois, the Mormons finally fled the United States in search of religious freedom. They settled in Utah in 1847, which was then part of Mexico. Consequently, the Mormons largely avoided the American Civil War from 1861-1865. The Mormons quickly forgave the United States, and allowed the transcontinental railroad to connect through Salt Lake City in 1869. Utah became a state in 1896. To this day, a significant portion of the population in Utah are Mormons. Despite their early rocky history with the United States, Mormons tend to be staunch supporters of the U.S. Constitution, and believe that it came partly by inspiration from God.
The Mormons had been forced out of their homes in New York, Ohio, Illinois, and Missouri. They wanted to practice their religion in peace, so they fled to the Rocky Mountains, where their prophet had predicted they could find refuge.
A lot!! So much, in fact, I don't think it could possibly fit into one answer. If your looking for what happened to the first group of Mormon Pioneers, I'd suggest going to:

Utah.
Utah was settled by Mormons.
Mormons founded Salt Lake City, Utah, the capital of Utah. Actually, they founded the whole state of Utah...
The Mormons were searching for a place where they could practice their religion in peace and found that place in Utah.
Nothing happened to the Mormons, they are still surviving and thriving as a 14 million member worldwide church. Brigham Young was their second leader, he moved Church headquarters to Utah in 1847, and it has been located there ever since.
Some say that the Mormons had to denounce polygamy before Utah became a state. This may or may not be true, as the plans to make Utah a state were in action before the Church officially denounced polygamy. Either way, Mormons arrived there in 1847, Utah became a territory in 1850, Mormons ended polygamy in 1890, and Utah became a state in 1896.
Utah is known for its snow, mormons, and beautiful national parks.
