Louisiana Purchase




Louisiana Purchase
In 1803, President Thomas Jefferson doubled the size of the United States by purchasing the Louisiana Territory from the French. This purchase troubled Jefferson somewhat because he used his presidential treaty-making powers to craft the agreement. He considered this to be a loose interpretation of these powers, and he believed that the Constitution should be interpreted strictly.
