Upper Louisiana (Illinois Country)
Lower Louisiana (Mississippi Delta)
Middle Louisiana (Arkansas Post area)

Louisiana Territory's Return to French Control

France regained control of the Louisiana Territory through the Third Treaty of San Ildefonso, signed on October 1, 1800. The secret agreement between Spanish King Charles IV and French leader Napoleon Bonaparte exchanged the territory for the creation of the Kingdom of Etruria in northern Italy for Charles IV's son-in-law.
