None.
When the pioneers came west in 1847 Utah was part of the country of Mexico and so was the area of present day Nevada. The majority of the pioneers settled in Utah.
After the Mexican-American war this area was ceded to the United States in 1848.
Nevada was part of the Utah Territory when Utah became a Territory in 1850.
Nevada Territory was created in 1861.
Nevada Statehood was in 1864.
Note: Some pioneers had settled near present day Las Vegas (the Muddy settlements), which area was not part of the Nevada Territory in 1861. In 1871 a new survey proved that the Muddy settlements were in the state of Nevada. When the Mormon settlers found out they were in Nevada they moved out and into Utah Territory.
Another settlement was created in Carson Valley in 1855 but was abandoned in 1857.
In an attempt to escape religious persecution, Mormon pioneers established many cities across the western United States. Nearly every city in Utah and many cities in southern Idaho and northern Arizona were settled by Mormon pioneers. They also settled cities in Nevada, California, Missouri, Illinois, Wisconsin, Mexico, and Canada.
Mormon pioneers settled many cities in the western and midwestern United States. The federal government drew the state boundaries and named the states.
In which area? The Church of Jesus Christ of Latter-day Saints (commonly called the "Mormon" church) is quite popular in the western United States because much of the area was settled by Mormon pioneers in the 1800's - especially Utah, Idaho, Arizona, Nevada, California, Washington, and Wyoming. They and their families have stayed in the area their numbers continue to grow. Many converts have also moved to the area to live closer to Church headquarters.
Approximately 70,000 Mormon Pioneers traveled the Mormon Trail between 1845 and 1869.
Do you mean the newest city which was settled by Mormons? The majority of the cities in Utah, southern Idaho, and northern Arizona, along with many in eastern Nevada, southern Canada, and northern Mexico, were settled by members of the Church of Jesus Christ of Latter-day Saints (commonly called the "Mormon" church) and majority of the population of these cities has remained mostly Mormon. It would be impossible to say which of these is the most recently founded. Salt Lake City, Utah can be considered the oldest remaining Mormon Settlement, although less than 50% of the city itself is a practicing Mormon. The majority of the other cities in Utah, Idaho, Arizona, Nevada, Canada, and Mexico were settled by Mormon pioneers between 1847 and 1900. These include small towns (such as Cardston in Alberta, Canada and Colonia Juarez in Chihuahua, Mexico) and large cities, like Las Vegas, Nevada. There is no such thing as a "Mormon Settlement" today. Since the early 1900's, the Church has encouraged it's members and converts to build up the Church in their local communities rather than gather to the west. With the huge influx of people moving to the west, there is no one city or settlement that is 100% Mormon. Utah is the state with the highest Mormon population, with about 50% being practicing Mormons. Mormons gladly accept the diversity of religions and cultures moving to the west, and most Mormons would rather not live in an insular "100% Mormon" society.
The Church of Jesus Christ of Latter-day Saints (the "Mormon" church) is quite popular in the western United States, especially Utah, Idaho, and Arizona. This is due to the fact that Mormon pioneers settled the region and many of their descendents still live in the same place and practice the same religion.
There are an unlimited number of places you could read about Mormon pioneers! There are several wonderful sources online and thousands of books, many of which might be available at your local library. For really in-depth study, the Church of Jesus Christ of Latter-day Saints (the "Mormon" church) has a library full of documents, journals, biographies, and books from and about the Mormon pioneers. This is probably the most comprehensive source of information on Mormon pioneers. It all depends on what kind of information you are looking for! If you would like some specific ideas, let me know what kind of information you are looking for in the "discussion" section of this question.
The Perpetual Immigration Fund was how many Mormon pioneers funded their trip to Utah.
The first group of Mormon pioneers started on the trail in the winter of 1845-46, but groups continued to use the trail until the railroad came in 1869.many of these groups were converts from Europe.
Brigham Young led the first group of Mormon pioneers to Utah, and over the next 30 years was the leader of the church while hundreds more pioneers travelled to Utah. Since Brigham Young died in 1877, there have been many leaders of the Mormon church. While each of these leaders have lived in Utah, they lead the entire worldwide church, not just members in Utah.
The most common form of transportation for pioneers among the Oregon and Mormon trails was by wagon. Usually wagons were pulled by a team of oxen although horses, mules, and cattle were sometimes used. Those looking for quick travel or who were traveling alone with few belongings might take just a horse, perhaps with an extra pack animal to carry supplies. The poorest pioneers travelled by foot (many without shoes!), some were able to get a wagon-owner to carry their supplies, and some had to carry their supplies alone. Many poor Mormon pioneers used what was called a 'handcart' - a shortened two-wheeled wagon which they had to pull or push themselves.
The European country that settled in Utah is the United States, specifically through the migration of Mormon pioneers from the Church of Jesus Christ of Latter-day Saints, predominantly from England and other parts of Europe. In the mid-19th century, these settlers established communities in the region, seeking refuge from religious persecution. Although the settlers were primarily American, many were of European descent, contributing to Utah's cultural and demographic landscape.
