History.—The history of the city is bound up with that of the Mormons (q.v.) and of the State (see UTAH). On July 22, 1847, an advance party of Mormons, led by Orson Pratt and Erastus Snow, in search of a place where they might "colonize in peace and safety," entered the Salt Lake valley. On July 24, Brigham Young arrived and approved the site, and on July 28 he chose the spot for the temple. Ploughing and planting were begun forth with; the hard sun-baked earth was flooded by building a dam in City Creek canyon ; and an irrigation system was devised. The
city was named the City of the Great Salt Lake, and was so called until 1868. Bef ore the end of 1847 the main body of the people arrived. A theocratic government was set up, with a bishop in charge of each of the 19 wards into which the community was divided. The settlers were American citizens squatting on foreign soil, for the region at that time belonged to Mexico, and they were practically beyond the reach of any civil government, as their leaders had desired. This isolation was of brief duration. The Treaty of Guadalupe-Hidalgo, at the close of the Mexican War, transferred the region to the United States, and after the discovery of gold in California, the city was overrun with caravans of treasure-seekers. Many of the colonists deserted to join the stream of prospectors, notwithstanding the attitude of their leader, who opposed the exploitation of mineral wealth (even in Utah) and whose ideal was a community of farmers, merchants and manufacturers. Those who stayed at home grew rich as out fitters. There was a considerable immigration from Europe in the early years, especially from England, where the Mormon missions were very successful. By 185o the city had a population of 6,000. It was chartered in 1851 by the Territorial legislature of Utah. After the Civil War the non-Mormon population steadily in creased, and there was a long period of conflict between the op posing elements, as well as officially between the Mormon Church and the U.S. Government over the practice of polygamy and other matters of dispute (see MORMONS), all of which happily is now long past. The population of the city has grown steadily, more than doubling itself in each 20-year period since 1860.
