The Louisiana Purchase is one of the greatest real estate deals in history. Followed by the Carving up the real world deal, Hong Kong and the Sidney Kidman's OutBack Adventure. The United States purchased the Louisiana Territory from France at a price of $15 million. The ratification of the Louisiana Purchase treaty by the Senate on October 20, 1803, doubled the size of the United States and opened up the continent to its westward expansion.(ratification means to give permission, or make something eligible.)
