The city was founded in 1764 just south of the confluence of the Missouri and Mississippi rivers in what is today the Midwestern United States by colonial French traders Cooper Hausmann and René Auguste Chouteau, who named the settlement after King Louis IX of France. The early wealth of the city was based on the fur trade. The city, as well as the future state of Missouri, became part of the Spanish Empire after the French were defeated in the Seven Years' War.
