From Thomas Jefferson Encyclopedia
The Louisiana Purchase (1803)  was a land deal between the United States and France, which gave the U.S. about 827,000 square miles of land west of the Mississippi River for $15 million dollars.
"This little event, of France's possessing herself of Louisiana . is the embryo of a tornado which will burst on the countries on both sides of the Atlantic and involve in it's effects their highest destinies."
President Thomas Jefferson wrote this prediction in an April 1802 letter to Pierre Samuel du Pont amid reports that Spain would retrocede to France the vast territory of Louisiana. As the United States had expanded westward, navigation of the Mississippi River and access to the port of New Orleans had become critical to American commerce, so this transfer of authority was cause for concern. Within a week of his letter to du Pont, Jefferson wrote U.S. Minister to France Robert Livingston: "Every eye in the U.S. is now fixed on this affair of Louisiana. Perhaps nothing since the revolutionary war has produced more uneasy sensations through the body of the nation."
The presence of Spain was not so provocative. A conflict over navigation of the Mississippi had been resolved in 1795 with a treaty in which Spain recognized the United States' right to use the river and to deposit goods in New Orleans for transfer to oceangoing vessels. In his letter to Livingston, Jefferson wrote, "Spain might have retained [New Orleans] quietly for years. Her pacific dispositions, her feeble state, would induce her to increase our facilities there, so that her possession of the place would be hardly felt by us." He went on to speculate that "it would not perhaps be very long before some circumstance might arise which might make the cession of it to us the price of something of more worth to her."
Jefferson's vision of obtaining territory from Spain was altered by the prospect of having the much more powerful France of Napoleon Bonaparte as a next-door neighbor.
France had surrendered its North American possessions at the end of the French and Indian War. New Orleans and Louisiana west of the Mississippi were transferred to Spain in 1762, and French territories east of the Mississippi, including Canada, were ceded to Britain the next year. But Napoleon, who took power in 1799, aimed to restore France's presence on the continent.
The Louisiana situation reached a crisis point in October 1802 when Spain's King Charles IV signed a decree transferring the territory to France and the Spanish agent in New Orleans, acting on orders from the Spanish court, revoked Americans' access to the port's warehouses. These moves prompted outrage in the United States.
While Jefferson and Secretary of State James Madison worked to resolve the issue through diplomatic channels, some factions in the West and the opposition Federalist Party called for war and advocated secession by the western territories in order to seize control of the lower Mississippi and New Orleans.
Aware of the need for action more visible than diplomatic maneuvering and concerned with the threat of disunion, Jefferson in January 1803 recommended that James Monroe join Livingston in Paris as minister extraordinary. (Later that same month, Jefferson asked Congress to fund an expedition that would cross the Louisiana territory, regardless of who controlled it, and proceed on to the Pacific. This would turn out to be the Lewis and Clark Expedition.) Monroe was a close personal friend and political ally of Jefferson's, but he also owned land in Kentucky and had spoken openly for the rights of the western territories.
Jefferson urged Monroe to accept the posting, saying he possessed "the unlimited confidence of the administration and of the western people." Jefferson added: "All eyes, all hopes, are now fixed on you . for on the event of this mission depends the future destinies of this republic."
Shortly thereafter, Jefferson wrote to Kentucky's governor, James Garrard, to inform him of Monroe's appointment and to assure him that Monroe was empowered to enter into "arrangements that may effectually secure our rights & interest in the Mississippi, and in the country eastward of that."
As Jefferson noted in that letter, Monroe's charge was to obtain land east of the Mississippi. Monroe's instructions, drawn up by Madison and approved by Jefferson, allocated up to $10 million for the purchase of New Orleans and all or part of the Floridas. If this bid failed, Monroe was instructed to try to purchase just New Orleans, or, at the very least, secure U.S. access to the Mississippi and the port.
Napoleon's plans to re-establish France in the New World were unraveling. The French army sent to suppress a rebellion by slaves and free blacks in the sugar-rich colony of Saint Domingue (present-day Haiti) had been decimated by yellow fever, and a new war with Britain seemed inevitable. France's minister of finance, Francois de Barbé-Marbois, who had always doubted Louisiana's worth, counseled Napoleon that Louisiana would be less valuable without Saint Domingue and, in the event of war, the territory would likely be taken by the British from Canada. France could not afford to send forces to occupy the entire Mississippi Valley, so why not abandon the idea of empire in America and sell the territory to the United States?
Napoleon agreed. On April 11, Foreign Minister Charles Maurice de Talleyrand told Livingston that France was willing to sell all of Louisiana. Livingston informed Monroe upon his arrival the next day.
Seizing on what Jefferson later called "a fugitive occurrence," Monroe and Livingston immediately entered into negotiations and on April 30 reached an agreement that exceeded their authority - the purchase of the Louisiana territory, including New Orleans, for $15 million. The acquisition of approximately 827,000 square miles would double the size of the United States.
Though rumors of the purchase preceded notification from Monroe and Livingston, their message reached Washington in time for an official announcement on July 4, 1803.
The purchase treaty had to be ratified by the end of October, which gave Jefferson and his Cabinet time to deliberate the issues of boundaries and constitutionality. Exact boundaries would have to be negotiated with Spain and England and so would not be set for several years, and Jefferson's Cabinet members argued that the constitutional amendment he proposed was not necessary. As time for ratification of the purchase treaty grew short, Jefferson accepted his Cabinet's counsel and rationalized: "It is the case of a guardian, investing the money of his ward in purchasing an important adjacent territory; and saying to him when of age, I did this for your good."
The Senate ratified the treaty Oct. 20 by a vote of 24 to 7. Spain, upset by the sale but without the military power to block it, formally returned Louisiana to France on Nov. 30. France officially transferred the territory to the Americans on Dec. 20, and the United States took formal possession on Dec. 30.
Jefferson's prediction of a "tornado" that would burst upon the countries on both sides of the Atlantic had been averted, but his belief that the affair of Louisiana would impact upon "their highest destinies" proved prophetic indeed.
