District of Louisiana
The District of Louisiana, or Louisiana District, was an official and temporary United States government designation for the portion of the Louisiana Purchase that had not been organized into the Territory of Orleans or "Orleans Territory" (the portion of the Louisiana Purchase south of the 33rd parallel, which is now the Arkansas–Louisiana state line). The district officially existed from March 10, 1804, until July 4, 1805, when it was organized as the Louisiana Territory.
