$15 million for 820,000 square miles. About 3 cents for an acre.
The U.S. paid $15 million to France for the Louisiana Territory in 1803, which doubled the size of the nation. This purchase was signed by U.S. ambassadors in Paris and was driven by President Thomas Jefferson's interest in securing control over New Orleans and the Mississippi River. Ultimately, the deal was seen as a great opportunity for expansion and development of agriculture in the U.S.
