Thomas Jefferson the Anti-Federalist
Thomas Jefferson was strongly anti-federalist. While he might have written the Declaration of Independence, he definitely did not author the Constitution. Instead, that document was mainly written by James Madison. Jefferson spoke against a strong federal government and instead advocated states' rights. He feared tyranny of any kind and only recognized the need for a strong, central government in terms of foreign affairs.
Jefferson's philosophy concerning the role of the central government can be most clearly seen when investigating his disagreement with Alexander Hamilton over the creation of a National Bank. Hamilton was a staunch supporter of a strong central government. While it a National Bank was not expressly mentioned in the Constitution, Hamilton felt that the elastic clause (Art I., Sect. 8, Clause 18) gave the government the power to create such a body. Jefferson completely disagreed. He felt that all powers given to the National Government were enumerated. If they were not expressly mentioned in the Constitution then they were reserved to the states.
How does this relate to the Louisiana Purchase? By completing this purchase, Jefferson had to put aside his principles because the allowance for this type of transaction was not expressly listed in the Constitution. Waiting for a Constitutional amendment might cause the deal to fall through. Therefore, Jefferson decided to go through with the purchase. Luckily, the people of the United States basically agreed that this was an excellent move.
Why did Jefferson feel this deal was so necessary? Because in 1801, Spain and France signed a secret treaty ceding Louisiana to France. France suddenly posed a potential threat to America. There was a fear that if America did not purchase New Orleans from France, it could lead to war. The change of ownership of this key port resulted in its closing to Americans. Therefore, Jefferson sent envoys to France to try and secure its purchase. Instead, they returned with an agreement to buy the entire Louisiana Territory. America did not have the money to pay the $15 million outright so they instead borrowed the money from Great Britain at 6% interest.
Importance of the Louisiana Purchase
With the purchase of this new territory, the land area of America nearly doubled. However, the exact southern and western boundaries were not defined in the purchase. America would have to deal with Spain to work out the specific details of these boundaries. Meriwether Lewis and William Clark led a small expeditionary group called the Corps of Discovery into the territory. They are just the beginning of America's fascination with exploring the west. Whether or not America had a 'Manifest Destiny' to span from 'sea to sea' as was often the rallying cry of the early to mid 19th century, the desire to control this territory cannot be denied.
What were the effects of Jefferson's decision to go against his own philosophy concerning a strict interpretation of the Constitution? It can be argued that his taking liberties with the Constitution in the name of need and expediency would lead to future Presidents feeling justified with a continual increase in the elasticity of Article I, Section 8, Clause 18. Jefferson should rightly be remembered for the great deed of purchasing this enormous tract of land. But one wonders if he might regret the means in which he earned this fame.
