In short
In 1803, the United States purchased roughly 828,000 square miles of territory from France for $15 million, doubling the nation's size overnight. The deal, negotiated by James Monroe and Robert Livingston in Paris, gave America control of the Mississippi River and New Orleans—critical for western expansion and trade. France, cash-strapped from wars in Europe and a failed campaign in Haiti, was willing to sell.
How it unfolded.
The five-minute version
What actually happened.
The Louisiana Purchase 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 fifteen million dollars, or approximately eighteen dollars per square mile ($7/km2), the United States nominally acquired a total of 828,000 sq mi of land now in the Central United States. However, France only controlled a small fraction of this area, most of which was inhabited by Native Americans; effectively, for the majority of the area, the United States bought the preemptive right to obtain Indian lands by treaty or by conquest, to the exclusion of other colonial powers.
