When President Thomas Jefferson bought the Louisiana Territory from cash-strapped France in 1803, he doubled the size of the United States without really knowing what he was getting. He dispatched Meriwether Lewis and William Clark and their Corps of Discovery to explore a territory that would include part or all of fifteen future states and to seek a water route to the West Coast.
