History of Lee County
Fort Madison dates to the War of 1812. Lee County was the location of the Half-Breed Tract, established by treaty in 1824. Allocations of land were made to American Indian descendants of European fathers and Indian mothers at this tract. Originally the land was to be held in common. Some who had an allocation lived in cities, where they hoped to make better livings. Lee County as a named entity was formed on December 7, 1836, under the jurisdiction of Wisconsin Territory. It would become a part of Iowa Territory when it was formed on July 4, 1838. Large-scale European-American settlement in the area began in 1839, after Congress allowed owners to sell land individually. Members of the Church of Jesus Christ of Latter-day Saints (LDS Church) under the direction of Brigham Young fled persecutions in Missouri to settle in Illinois and Iowa.
