Orleans Territory
Orleans Territory was one half of the first subdivision of the Louisiana Purchase. Orleans Territory is what we today think of as the State of Louisiana, the remaining land was known as Louisiana Territory or the District of Louisiana (later Missouri Territory). Orleans Territory was created on March 26, 1804, and became Louisiana, the 18th U.S. state, on March 30, 1812.
Orleans Territory was the land south of the Mississippi Territory and south of the 33rd parallel, west of the Mississippi River, within the Louisiana Purchase.
