The District of Louisiana, or Louisiana District, was an official, temporary, United States government designation for the portion of the Louisiana Purchase that had not been organized into the Orleans Territory. It officially existed from March 10, 1804 until July 4, 1805, when it was incorporated as the Louisiana Territory. The area north of present-day Arkansas was commonly referred to as Upper Louisiana.[citation needed] The United States District of Louisiana had two incarnations: first, as a federally administered military district (March 10, 1804 - September 30, 1804); then as an organized territory (October 1, 1804 - July 4, 1805) under the jurisdiction of the Indiana Territory.
