With the so-called Louisiana Purchase, the United States purchased the French colonial possessions in North America (approximately 828,000 sq mi or 2,140,000 km2) for fifteen million dollars in 1803. This territory was clearly unincorporated at the time of the purchase and is thus treated as such. The territory was then divided in several different unincorporated territories, and the Louisiana Territory was soon reduced to roughly the modern-day U.S. state of Louisiana.
Establishment
December 1803: "Louisiana Purchase": acquisition of the territory of Louisiana by the United States from France. In return for $15 million, or approximately eighteen dollars per square mile, the United States nominally acquired a total of 828,000 sq mi (2,140,000 km2; 530,000,000 acres). The purchase was completed on December, 20 1803.
