Because of its location along the Missouri River, St. Charles served as a major hub of trade after its settlement in 1673 by French settlers exploring the tributaries of the Mississippi River. The area grew rapidly after Daniel Boone moved to the area in 1799 and settled in what is now Defiance, an unincorporated community within the county. The city of St. Charles became a hub of activity and served as the starting point of Lewis and Clark's Corps of Discovery Expedition. After Missouri gained statehood, St. Charles served as the state capitol from 1821 to 1826. The Missouri, Kansas, and Texas railroad was completed in 1894 and ran through the county. This newfound transportation opportunity brought further growth and settlers to the region. Today, this method of transportation has been replaced by an efficient interstate network. However, the railroad's footprint lives on through the 240-mile Katy Trail State Park. This park consists of a trail system built along the former railroad tracks. The park's jogging, biking, and hiking trails create an east-west path through the entire state.
