Louisiana Purchase, 1803. 1  The Louisiana Purchase encompassed 530,000,000 acres of territory in North America that the United States purchased from France in 1803 for $15 million.
The Louisiana Purchase was an incredible deal for the United States, the final cost totaling less than five cents per acre at $15 million (about $283 million in today's dollars). France's land was mainly unexplored wilderness, and so the fertile soils and other valuable natural resources we know are present today might not have been factored in the relatively low cost at the time.
