American Confluence: The Missouri Frontier from Borderland to Border State

In the heart of North America, the Missouri, Ohio, and Mississippi rivers
come together, uniting waters from west, north, and east on a journey to the south.
This is the region that Stephen Aron calls the American Confluence. Aron's
innovative book examines the history of that region -- a home to the Osage, a colony
exploited by the French, a new frontier explored by Lewis and Clark -- and focuses
on the region's transition from a place of overlapping borderlands to one of
oppositional border states. American Confluence is a lively account that will
delight both the amateur and professional historian.
