This illustration from Henry Lewis' Das Illustrirte Mississipithal
depicts the large temple built by the Church of Latter-Day Saints (or
Mormons) at Nauvoo, Illinois. The Mormons came to Illinois in 1832, fleeing
persecution in Missouri. By 1842 Nauvoo had become a city of at least
12,000, the largest in Illinois. Thousands of other Latter-Day Saints
lived nearby. The church erected a massive temple. Insisting upon controlling
local institutions, the Latter-Day Saints assembled the Nauvoo Legion,
a well-trained Mormon army provided cannon by Springfield officials eager
to court the bloc-voting sect. The Mormons' exclusive social and economic
organization and clumsy attempts to influence Illinois politics quickly
led to controversy with other Illinoisans. By 1844 Illinois Governor Thomas
Ford had called out the state militia to quell the growing conflict. In
June of that year an anti-Mormon mob rushed the jail holding the Saints'
leader Joseph Smith and his brother Hyrum and murdered them. Despite the
governor's ineffectual efforts to keep the peace, lawlessness persisted
for two years in what has come to be known as the Mormon War. In 1846
the Mormons quit Illinois and began their trek to Deseret, the modern
Salt Lake Valley of Utah.
