The Mormons in Hancock County
About 1839, the Mormons came to the town of Commerce. The settlement was renamed Nauvoo (Beautiful Place). From 1839-1846, Nauvoo was Illinois' largest (population 20,000) and most politically powerful town. In June of 1844, the Mormon prophet and leader, Joseph Smith, and his brother Hyrum Smith were killed by a mob while detained in the jail at Carthage. The Mormon exodus from Nauvoo began in early 1846 as they traveled across the Great Plains to their new headquarters in Utah.
