In 1803, emissaries from the American President, including future President James Monroe, signed a treaty, which was then the largest real estate purchase in history. Thomas Jefferson authorized his ambassadors to sign the Louisiana Purchase Treaty despite some misgiving he had about its constitutionality. He did it because he thought it was a great deal (it was – 15 million bucks for property which would later make up parts of 14 states), and because he wanted to enhance American security.
He was opposed in his efforts to make the purchase by Federalists, who while they appreciated the expansion of federal power (being Federalists and all), didn’t like so much money going to a sworn enemy of the English, who they liked. So, the Federalists made a big stink about Jefferson’s lack of philosophical consistency, as they themselves showed that they lacked any philosophical consistency by opposing an expansion of federal power, which philosophically, they supported.
Had Jefferson been a stickler for his philosophy, American history would have taken a dramatically different course. Instead of a sprawling and vibrant democracy powered by Manifest Destiny in the 19th and 20th centuries, the United States would have been hemmed in by European powers France, Spain and Great Britain, where it would have become at best a second-rate power.
