Seven years after Great Britain officially conceded Spanish ownership of the territory to the Spanish, France acquired the territory by the secret Treaty of San Ildefonso.
Then in 1803, the The Louisiana Purchase land deal, between the United States and France, doubled the size of the U.S. and made the future state of Missouri part of America.
In 1812, settlers organized Missouri as its own territory apart from the Louisiana territory.
