Louisiana Purchase

France was slow in taking control of Louisiana, but in 1802 Spanish authorities, apparently acting under French orders, revoked a U.S.-Spanish treaty that granted Americans the right to store goods in New Orleans. In response, Jefferson sent future U.S. presidentJames Monroe (1758-1831) to Paris to aid Livingston in the New Orleans purchase talks. In mid-April 1803, shortly before Monroe’s arrival, the French asked a surprised Livingston if the United States was interested in purchasing all of Louisiana Territory. It is believed that the failure of France to put down a slave revolution in Haiti, the impending war with Great Britain and probable British naval blockade of France, and financial difficulties may all have prompted Napoleon to offer Louisiana for sale to the United States.Negotiations moved swiftly, and at the end of April the U.S. envoys agreed to pay $11,250,000 and assume claims of American citizens against France in the amount of $3,750,000. In exchange, the United States acquired the vast domain of Louisiana Territory, some 828,000 square miles of land. The treaty was dated April 30 and signed on May 2. In October, the U.S. Senate ratified the purchase, and in December 1803 France transferred authority over the region to the United States.
