Today in 1764 the city of St. Louis was established by French trader Pierre Laclède and his 14 year old stepson, Auguste Chouteau, in the Viceroyalty of New Spain on land the Osage people considered their territory. The United States acquired the territory in the Louisiana Purchase. Lewis and Clark set out on their expedition from St. Louis, returning to settle there at its conclusion. The city would famously become the Gateway to the west as wagon trains launched onto the Oregon Trail in their footsteps. Here the site of the city is not yet reflected at the confluence of the Missouri and Mississippi Rivers on Cassini’s Gli Stati Uniti Dell’ America of 1797. Note the branch of the river labeled Osage to the west.
