Brief History of Mormon Settlement in Utah

“At the time the Mormons chose their new homeland on the Great Salt Lake and settled down to farm, their colony was in Mexican domain several hundred miles beyond the jurisdiction of the United states, while Bridger and Vasquez held their lands, totaling nine-square miles, under a grant from the Mexican government. Within a few months [February, 1848] the terms of peace at the close of the Mexican War threw them all into United States territory. . . .

As soon as [the Mormons] found themselves living once again in United States territory, they held a meeting, revowed allegiance to the Constitution and organized their own independent state, calling it Deseret. his was in 1849, so it will be readily understood with what curiosity the gold-seekers visited the Mormon colony. In 1850, Congress (which had ignored the state of Deseret) created the territory of Utah, cleverly appointing Brigham Young its governor. He accepted and took oath February 3, 1851.”
