The city was founded in 1847 by Brigham Young and his Mormon followers. They extensively irrigated and cultivated the arid valley. Due to its proximity to the Great Salt Lake, the city was originally named "Great Salt Lake City"–the word "great" was dropped from the official name in 1868. Although Salt Lake City is still home to the headquarters of The Church of Jesus Christ of Latter-day Saints (LDS Church), less than half the population of Salt Lake City proper is Mormon today.
