Louisiana Purchase

1803 acquisition of region of Middle America land by the U.S. from France

The Louisiana Purchase (French: Vente de la Louisiane, lit. 'Sale of Louisiana') was the acquisition of the territory of Louisiana by the United States from the French First Republic in 1803. This consisted of most of the land in the Mississippi River's drainage basin west of the river. In return for $15 million, or approximately $18 per square mile ($7/km²), the United States nominally acquired a total of 828,000 sq mi (2,140,000 km²; 530,000,000 acres) of land now in the Central United States.
