Louisiana Purchase: A Legislative Timeline

1802-1803 (7th Congress, 2nd Session)

As a result of the Spanish administrative official in New Orleans rescinding the right of deposit, leaving frontier settlers without access to markets for their produce, Thomas Jefferson begins his campaign to learn if the French might be willing to consider selling New Orleans (and, eventually, all of the Louisiana territory), working toward appropriating funds for the purchase.
