On December 20, 1803, officials gathered in the Cabildo in New Orleans for one of the strangest handovers in history.

Spain had only just returned the colony to France on November 30, so France held it for barely twenty days.
For about $15 million, the United States acquired roughly 828,000 square miles, land that would form all or part of fifteen future states. The deal cost less than five cents an acre and nearly doubled the size of the nation overnight.
