Mormons founded which us state capitol city?
Mormons founded Salt Lake City, Utah, the capital of Utah. Actually, they founded the whole state of Utah...
Mormons founded hundreds of cities, mostly in the Western US but some in the midwest, Canada, and Mexico. Nearly every city in Utah and most in southern Idaho and northern Arizona were founded by Mormons. Some of the more well-known cities founded by Mormons are Salt Lake City, Utah and Las Vegas, Nevada.
The Mormons went to Utah to avoid persecution by hostile mobs. They had been chased out of almost every city or state they had inhabited or founded. Some had been killed and Missouri even made it legal to kill any Mormon of any age if they didn't leave their property and much of their belongings and leave the state.
