How the Louisiana Purchase Changed the World

When Thomas Jefferson purchased the Louisiana Territory from France, he altered the shape of a nation and the course of history

Louisiana Purchase

UNDERSTANDABLY, Pierre Clément de Laussat was saddened by this unexpected turn of events. Having arrived in New Orleans from Paris with his wife and three daughters just nine months earlier, in March 1803, the cultivated, worldly French functionary had expected to reign for six or eight years as colonial prefect over the vast territory of Louisiana, which was to be France’s North American empire. The prospect had been all the more pleasing because the territory’s capital, New Orleans, he had noted with approval, was a city with “a great deal of social life, elegance and goodbreeding.” He also had liked the fact that the city had “all sorts of masters—dancing, music, art, and fencing,” and that even though there were “no book shops or libraries,” books could be ordered from France.

But almost before Laussat had learned to appreciate a good gumbo and the relaxed Creole pace of life, Napoléon Bonaparte had abruptly decided to sell the territory to the United States. This left Laussat with little to do but officiate when, on a sunny December 20, 1803, the French tricolor was slowly lowered in New Orleans’ main square, the Placed’Armes, and the American flag was raised. After William C.C. Claiborne and Gen. James Wilkinson, the new commissioners of the territory, officially took possession of it in the name of the United States, assuring all residents that their property, rights and religion would be respected, celebratory salvos boomed from the forts around the city. Americans cried “Huzzah!” and waved their hats, while French and Spanish residents sulked in glum silence. Laussat, standing on the balcony of the town hall, burst into tears.

The Louisiana Purchase, made 200 years ago this month, nearly doubled the size of the United States. By any measure, it was one of the most colossal land transactions in history, involving an area larger than today’s France, Spain, Portugal, Italy, Germany, Holland, Switzerland and the British Isles combined. All or parts of 15 Western states would eventually be carved from its nearly 830,000 square miles, which stretched from the Gulf of Mexico to Canada, and from the Mississippi River to the Rocky Mountains. And the price, $15 million, or about four cents an acre, was a breathtaking bargain. “Let the Land rejoice,” Gen. Horatio Gates, a prominent New York state legislator, told President Thomas Jefferson when details of the deal reached Washington, D.C. “For you have bought Louisiana for a song.”

Rich in gold, silver and other ores, as well as huge forests and endless lands for grazing and farming, the new acquisition would make America immensely wealthy. Or, as Jefferson put it in his usual understated way, “The fertility of thecountry, its climate and extent, promise in due season importantaids to our treasury, an ample provision for our posterity, and a wide-spread field for the blessings of freedom.”

American historians today are more outspoken in their enthusiasm for the acquisition. “With the Declaration of Independence and the Constitution, this is one of the threethings that created the modern United States,” says Douglas Brinkley, director of the Eisenhower Center for American Studies in New Orleans and coauthor with the late Stephen E. Ambrose of The Mississippi and the Making of a Nation . Charles A. Cerami, author of Jefferson’s Great Gamble, agrees. “If we had not made this purchase, it would have pinched off the possibility of our becoming a continental power,” he says. “That, in turn, would have meant our ideas on freedom and democracy would have carried less weight with the rest of the world. This was the key to our international influence.”

The bicentennial is being celebrated with yearlong activities in many of the states fashioned from the territory. But the focal point of the celebrations is Louisiana itself. The most ambitious event opens this month at the New Orleans Museum of Art. “Jefferson’s America & Napoléon’s France” (April 12-August 31), an unprecedented exhibition of paintings, sculptures, decorative arts, memorabilia and rare documents, presents a dazzling look at the arts and leading figures of the two countries at this pivotal time in history. “What we wanted to do was enrich people’s understanding of the significance of this moment,” says Gail Feigenbaum, lead curator of the show. “It’s about more than just a humdinger of a real estate deal. What kind of world were Jefferson and Napoléon living and working in? We also show that our political and cultural relationship with France was extraordinarily rich at the time, a spirited interchange that altered the shape of the modern world.”

The “Louisiana territory” was born on April 9, 1682, when the French explorer Robert Cavelier, Sieur (Lord) de La Salle, erected a cross and column near the mouth of the Mississippi and solemnly read a declaration to a group of bemused Indians. He took possession of the whole Mississippi River basin, he avowed, in the name of “the most high, mighty, invincible and victorious Prince, Louis the Great, by Grace of God king of France and Navarre, 14th of that name.” And it was in honor of Louis XIV that he named the land Louisiana.

In 1718, French explorer Jean-Baptiste le Moyne, Sieur de Bienville, founded a settlement near the site of La Salle’s proclamation, and named it la Nouvelle Orléans for Philippe, Duke of Orléans and Regent of France. By the time of the Louisiana Purchase, its population of whites, slaves of African origin and “free persons of color” was about 8,000. A picturesque assemblage of French and Spanish colonial architecture and Creole cottages, New Orleans boasted a thriving economy based largely on agricultural exports.

For more than a century after La Salle took possession of it, the Louisiana Territory, with its scattered French, Spanish, Acadian and German settlements, along with those of Native Americans and American-born frontiersmen, was traded among European royalty at their whim. The French were fascinated by America—which they often symbolized in paintings and drawings as a befeathered Noble Savage standing beside an alligator—but they could not decide whether it was a new Eden or, as the naturalist Georges-Louis Leclerc de Buffon declared, a primitive place fit only for degenerate life-forms. But the official view was summed up by Antoine de La Mothe Cadillac, whom Louis XIV named governor of the territory in 1710: “The people are aheap of the dregs of Canada,” he sniffed in a 42-page report to the king written soon after he arrived. The soldiers there were untrained and undisciplined, he lamented, and the whole colony was “not worth a straw at the present time.” Concluding that the area was valueless, Louis XV gave the territory to his Bourbon cousin Charles III of Spain in 1763. But in 1800, the region again changed hands, when Napoléon negotiated the clandestine Treaty of San Ildefonso with Spain’s Charles IV. The treaty called for the return of the vast territory to France in exchange for the small kingdom of Etruria in northern Italy, which Charles wanted for his daughter Louisetta.

When Jefferson heard rumors of Napoléon’s secret deal, he immediately saw the threat to America’s Western settlements and its vital outlet to the Gulf of Mexico. If the deal was allowed to stand, he declared, “it would be impossible that France and the United States can continue long as friends.” Relations had been relaxed with Spain while it held New Orleans, but Jefferson suspected that Napoléon wanted to close the Mississippi to American use. This must have been a wrenching moment for Jefferson, who had long been a Francophile. Twelve years before, he had returned from a five-year stint as American minister to Paris, shipping home 86 cases of furnishings and books he had picked up there.

The crunch came for Jefferson in October 1802. Spain’s King Charles IV finally got around to signing the royal decree officially transferring the territory to France, and on October 16, the Spanish administrator in New Orleans, Juan Ventura Morales, who had agreed to administer the colony until his French replacement, Laussat, could arrive, arbitrarily ended the American right to deposit cargo in the city duty-free. He argued that the three-year term of the 1795 treaty that had granted America this right and free passage through Spanish territory on the Mississippi had expired. Morales’ proclamation meant that American merchandise could no longer be stored in New Orleans warehouses. As a result, trappers’ pelts, agricultural produce and finished goods risked exposure and theft on open wharfs while awaiting shipment to the East Coast and beyond. The entire economy of America’s Western territories was in jeopardy. “The difficulties and risks . . . are incalculable,” warned the U.S. vice-consul in New Orleans, Williams E. Hulings, in a dispatch to Secretary of State James Madison.

As Jefferson had written in April 1802 to the U.S. minister in Paris, Robert R. Livingston, it was crucial that the port of New Orleans remain open and free for American commerce, particularly the goods coming down the Mississippi River. “There is on the globe one single spot,” Jefferson wrote, “the possessor of which is our natural and habitual enemy. It is New Orleans, through which the produce of three-eighths of our territory must pass to market.” Jefferson’s concern was more than commercial. “He had a vision of America as an empire of liberty,” says Douglas Brinkley. “And he saw the Mississippi River not as the western edge of the country, but as the great spine that would hold the continent together.”

As it was, frontiersmen, infuriated by the abrogation of the right of deposit of their goods, threatened to seize New Orleans by force. The idea was taken up by lawmakers such as Senator James Ross of Pennsylvania, who drafted a resolution calling on Jefferson to form a 50,000-man army to take the city. The press joined the fray. The United States had the right, thundered the New York Evening Post, “to regulate the future destiny of North America,” while the Charleston Courier advocated “taking possession of the port . . . by force of arms.” As Secretary of State James Madison explained, “The Mississippi is to them everything. It is the Hudson, the Delaware, the Potomac, and all the navigable rivers of the Atlantic States, formed into one stream.”

With Congress and a vociferous press calling for action, Jefferson faced the nation’s most serious crisis since the American Revolution. “Peace is our passion,” he declared, and expressed the concern that hotheaded members of the opposition Federalist Party might “force us into war.” He had already instructed Livingston in early 1802 to approach Napoléon’s foreign minister, Charles Maurice de Talleyrand, to try to prevent the cession of the territory to France, if this had not already occurred, or, if the deal was done, to try to purchase New Orleans. In his initial meeting with Napoléon after taking up his Paris post in 1801, Livingston had been warned about Old World ways. “You have come to a very corrupt world,” Napoléon told him frankly, adding roguishly that Talleyrand was the right man to explain what he meant by corruption.

A wily political survivor who held high offices under the French Revolution, and later under Napoléon’s empire and the restored Bourbon monarchy, Talleyrand had spent the years 1792 to 1794 in exile in America after being denounced by the revolutionary National Convention, and had conceived a virulent contempt for Americans. “Refinement,” he declared, “does not exist” in the United States. As Napoléon’s foreign minister, Talleyrand customarily demanded outrageous bribes for diplomatic results. Despite a clubfoot and what contemporaries called his “dead eyes,” he could be charming and witty when he wanted—which helped camouflage his basic negotiating tactic of delay. “The lack of instructions and the necessity of consulting one’s government are always legitimate excuses in order to obtain delays in political affairs,” he once wrote. When Livingston tried to discuss the territory, Talleyrand simply denied that there was any treaty between France and Spain. “There never was a government in which less could be done by negotiation than here,” a frustrated Livingston wrote to Madison on September 1, 1802. “There is no people, no legislature, no counselors. One man is everything.”

But Livingston, although an inexperienced diplomat, tried to keep himself informed about the country to which he was ambassador. In March 1802, he warned Madison that France intended to “have a leading interest in the politics of our western country” and was preparing to send 5,000 to 7,000 troops from its Caribbean colony of Saint Domingue (now Haiti) to occupy New Orleans. But Napoléon’s troops in Saint Domingue were being decimated by a revolution and an outbreak of yellow fever. In June, Napoléon ordered Gen. Claude Victor to set out for New Orleans from the French controlled Netherlands. But by the time Victor assembled enough men and ships in January 1803, ice blocked the Dutchport, making it impossible for him to set sail.

That same month Jefferson asked James Monroe, a former member of Congress and former governor of Virginia, to join Livingston in Paris as minister extraordinary with discretionary powers to spend $9,375,000 to secure New Orleans and parts of the Floridas (to consolidate the U.S. position in the southeastern part of the continent). In financial straits at the time, Monroe sold his china and furniture to raise travel funds, asked a neighbor to manage his properties, and sailed for France on March 8, 1803, with Jefferson’s parting admonition ringing in his ears: “The future destinies of this republic” depended on his success.

By the time Monroe arrived in Paris on April 12, the situation had, unknown to him, radically altered: Napoléon had suddenly decided to sell the entire Louisiana Territory to the United States. He had always seen Saint Domingue, with a population of more than 500,000, producing enough sugar, coffee, indigo, cotton and cocoa to fill some 700 ships a year, as France’s most important holding in the Western Hemisphere. The Louisiana Territory, in Napoléon’s view, was useful mainly as a granary for Saint Domingue. With the colony in danger of being lost, the territory was less useful. Then, too, Napoléon was gearing up for another campaign against Britain and needed funds for that.

Napoléon’s brothers Joseph and Lucien had gone to see him at the Tuileries Palace on April 7, determined to convince him not to sell the territory. For one thing, they considered it foolish to voluntarily give up an important French holding on the American continent. For another, Britain had unofficially offered Joseph a bribe of £100,000 to persuade Napoléon not to let the Americans have Louisiana. But Napoléon’s mind was already made up. The First Consul happened to be sitting in his bath when his brothers arrived. “Gentlemen,” he announced, “think what you please about it. I have decided to sell Louisiana to the Americans.” To make his point to his astonished brothers, Napoléon abruptly stood up, then dropped back into the tub, drenching Joseph. A manservant slumped to the floor in a faint.

French historians point out that Napoléon had several reasons for this decision. “He probably concluded that, following American independence, France couldn’t hope to maintain a colony on the American continent,” says Jean Tulard, one of France’s foremost Napoléon scholars. “French policy makers had felt for some time that France’s possessions in the Antilles would inevitably be ‘contaminated’ by America’s idea of freedom and would eventually take their own independence. By the sale, Napoléon hoped to create a huge country in the Western Hemisphere to serve as a counterweight to Britain and maybe make trouble for it.”

On April 11, when Livingston called on Talleyrand for what he thought was yet another futile attempt to deal, the foreign minister, after the de rigueur small talk, suddenly asked whether the United States would perchance wish to buy the whole of the Louisiana Territory. In fact, Talleyrand was intruding on a deal that Napoléon had assigned to the French finance minister, François de Barbé-Marbois. The latter knew America well, having spent some years in Philadelphia in the late 1700s as French ambassador to the United States, where he got to know Washington, Jefferson, Livingston and Monroe. Barbé-Marbois received his orders on April 11, 1803, when Napoléon summoned him. “I renounce Louisiana,” Napoléon told him. “It is not only New Orleans that I will cede, it is the whole colony without reservation. I renounce it with the greatest regret. . . . I require a great deal of money for this war [with Britain].”

Thierry Lentz, a Napoléon historian and director of the Fondation Napoléon in Paris, contends that, for Napoléon, “It was basically just a big real estate deal. He was in a hurry to get some money for the depleted French treasury, although the relatively modest price shows that he was had in that deal. But he did manage to sell something that he didn’t really have any control over—there were few French settlers and no French administration over the territory—except on paper.” As for Jefferson, notes historian Cerami, “he actually wasn’t out to make this big a purchase. The whole thing came as a total surprise to him and his negotiating team in Paris, because it was, after all, Napoléon’s idea, not his.”

Showing up unexpectedly at the dinner party Livingston gave on April 12 for Monroe’s arrival, Barbé-Marbois discreetly asked Livingston to meet him later that night at the treasury office. There he confirmed Napoléon’s desire to sell the territory for $22,500,000. Livingston replied that he“would be ready to purchase provided the sum was reduced to reasonable limits.” Then he rushed home and worked until 3 a.m. writing a memorandum to Secretary of State Madison, concluding: “We shall do all we can to cheapen the purchase; but my present sentiment is that we shall buy.”

On April 15, Monroe and Livingston proposed $8 million.

At this, Barbé-Marbois pretended Napoléon had lost interest. But by April 27, he was saying that $15 million was as low as Napoléon would go. Though the Americans then countered with $12.7 million, the deal was struck for $15 million on April 29. The treaty was signed by Barbé-Marbois, Livingston and Monroe on May 2 and backdated to April 30. Although the purchase was undeniably a bargain, the price was still more than the young U.S. treasury could afford. But the resourceful Barbé-Marbois had an answer for that too. He had contacts at Britain’s Baring & Co. Bank, which agreed, along with several other banks, to make the actual purchase and pay Napoléon cash. The bank then turned over ownership of the Louisiana Territory to the United States in return for bonds, which were repaid over 15 years at 6 percent interest, making the final purchase price around $27 million. Neither Livingston nor Monroe had been authorized to buy all of the territory, or to spend $15 million—transatlantic mail took weeks, sometimes months, each way, so they had no time to request and receive approval of the deal from Washington. But an elated Livingston was aware that nearly doubling the size of America would make it a major player on the world scene one day, and he permitted himself some verbal euphoria: “We have lived long, but this is the noblest work of our whole lives,” he said. “From this day the United States take their place among the powers of the first rank.”

It wasn’t until July 3 that news of the purchase reached U.S. shores, just in time for Americans to celebrate it on Independence Day. A Washington newspaper, the National Intelligencer , reflecting how most citizens felt, referred to the “widespread joy of millions at an event which history will record among the most splendid in our annals.” Though we have no historical evidence of how Jefferson felt about the purchase, notes Cerami, reports from those in his circle like Monroe refer to the president’s “great pleasure,” despite his fear that the deal had gone beyond his constitutional powers. Not all Americans agreed, however. The Boston Columbian Centinel editorialized, “We are to give money of which we have too little for land of which we already have too much.” And Congressman Joseph Quincy of Massachusetts so opposed the deal that he favored secession by the Northeastern states, “amicably if they can; violently if they must.”

The favorable majority, however, easily prevailed and New England remained in the Union. As for the ever-succinct Thomas Jefferson, he wasted little time on rhetoric. “The enlightened government of France saw, with just discernment,” he told Congress, with typical tact, on October 17, 1803, “the importance to both nations of such liberal arrangements as might best and permanently promote the peace, friendship, and interests of both.” But, excited by the commercial opportunities in the West, Jefferson, even before official notice of the treaty reached him, had already dispatched Meriwether Lewis to lead an expedition to explore the territory and the lands beyond. All the way to the Pacific.

JEFFERSON’S AMERICA, NAPOLEON’S FRANCE

“We have tried to capture the suspense and fascination of a story whose outcome is known, yet was not foreordained,” says Gail Feigenbaum, curator of the Jefferson-Napoléon show on view in New Orleans April 12 to August 31, “and to tell it through a rich variety of objects.” The variety includes three important documents: a copy of the treaty, which bears Jefferson’s signature; a document covering payment of claims by American citizens against France, signed by Napoléon; and the official report of transfer of the Louisiana Territory signed by a bereaved prefect, Pierre de Laussat. The exhibition points up how intertwined the two nations were at the time. A seascape portrays the Marquis de Lafayette’s ship La Victoire setting sail to carry him across the Atlantic in 1777 to fight in the American Revolution. (There is also a portrait of the marquis himself and a 1784 painting by French artist Jean Suau, Allegory of France Liberating America.) A mahogany and gilded bronze swan bed that belonged to the famous French beauty Juliette Récamier is also on display. Fashion-conscious American ladies reportedly imitated Récamier’s attire, but not her custom of receiving visitors in her bedroom. And John Trumbull’s huge painting The Signing of the Declaration of Independence documents the historic American event that so greatly impressed and influenced French revolutionary thinkers. It hangs not far from a color engraving of the French Declaration of the Rights of Man, which was composed in 1789 by Lafayette with the advice of his American friend Thomas Jefferson.

Louisiana Purchase

The Louisiana Purchase of 1803 brought into the United States about 828,000 square miles of territory from France, thereby doubling the size of the young republic. What was known at the time as the Louisiana Territory stretched from the Mississippi River in the east to the Rocky Mountains in the west and from the Gulf of Mexico in the south to the Canadian border in the north. Part or all of 15 states were eventually created from the land deal, which is considered one of the most important achievements of Thomas Jefferson’s presidency.

France in the New World

Beginning in the 17th century, France explored the Mississippi River valley and established scattered settlements in the region.

By the middle of the 18th century, France controlled more of the present-day United States than any other European power: from New Orleans northeast to the Great Lakes and northwest to modern-day Montana .

In 1762, during the French and Indian War , France ceded French Louisiana west of the Mississippi River to Spain and in 1763 transferred nearly all of its remaining North American holdings to Great Britain. Spain, no longer a dominant European power, did little to develop Louisiana during the next three decades.

Louisiana Territory Changes Hands

In 1796, Spain allied itself with France, leading Britain to use its powerful navy to cut off Spain from America. And in 1801, Spain signed a secret treaty with France to return the Louisiana Territory to France.

Reports of the retrocession caused considerable unease in the United States. Since the late 1780s, Americans had been moving westward into the Ohio River and Tennessee River valleys, and these settlers were highly dependent on free access to the Mississippi River and the strategic port of New Orleans.

U.S. officials feared that France, resurgent under the leadership of Napoleon Bonaparte , would soon seek to dominate the Mississippi River and access to the Gulf of Mexico . In a letter to U.S. minister to France Robert Livingston, President Thomas Jefferson stated, “The day that France takes possession of New Orleans…we must marry ourselves to the British fleet and nation.”

Livingston was ordered to negotiate with French Finance Minister Barbé-Marbois for the purchase of New Orleans.

Louisiana Purchase Negotiations

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. president James Monroe 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’s 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 – combined with French economic difficulties – may 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.

Legacy of the Louisiana Purchase

The acquisition of the Louisiana Territory for the bargain price of less than three cents an acre was among Jefferson’s most notable achievements as president. American expansion westward into the new lands began immediately, and in 1804 a territorial government was established.

Jefferson soon commissioned the Lewis and Clark Expedition , led by Meriwether Lewis and William Clark, to explore the territory acquired in the Louisiana Purchase.

On April 30, 1812, exactly nine years after the Louisiana Purchase agreement was made, the first state to be carved from the territory – Louisiana – was admitted into the Union as the 18th U.S. state.

Louisiana Purchase

The Louisiana Purchase was the purchase of imperial rights to the western half of the Mississippi River basin from France by the United States in 1803. The deal granted the United States the sole authority to obtain the land from its indigenous inhabitants, either by contract or by conquest. The total price was $27,267,622. It was ultimately the greatest land bargain in U.S. history.

What was the impact of the Louisiana Purchase?

The Louisiana Purchase eventually doubled the size of the United States , greatly strengthened the country materially and strategically, provided a powerful impetus to westward expansion, and confirmed the doctrine of implied powers of the federal Constitution .

Where was the Louisiana Purchase signed?

The Louisiana Purchase was signed in Paris, France, by Robert Livingston and James Monroe on May 2, 1803, but the treaty was antedated to April 30.

Though it was not immediately apparent to constructionists such as U.S. President Thomas Jefferson , the Louisiana Purchase was ultimately determined to be constitutional. Jefferson thought that an amendment to the Constitution of the United States might be required to legalize the transaction, but the Senate approved the treaty by a vote of 24 to 7.

The Louisiana Purchase signified the United States ’ acquisition of imperial rights to land that was still largely occupied by Native American peoples , and it began a treaty process with those peoples that lasted over 150 years. Historically, the U.S. government’s compensation for cessions of indigenous rights to the land west of the Mississippi River was inequitable.

Louisiana Purchase , western half of the Mississippi River basin purchased in 1803 from France by the United States ; at less than three cents per acre for 828,000 square miles (2,144,520 square km), it was the greatest land bargain in U.S. history. The purchase doubled the size of the United States, greatly strengthened the country materially and strategically, provided a powerful impetus to westward expansion, and confirmed the doctrine of implied powers of the federal Constitution .

The Louisiana Territory had been the object of Old World interest for many years before 1803. Explorations and scattered settlements in the 17th and 18th centuries had given France control over the river and title to most of the Mississippi valley.

The first serious disruption of French control over Louisiana came during the Seven Years’ War . In 1762 France ceded Louisiana west of the Mississippi River to Spain and in 1763 transferred virtually all of its remaining possessions in North America to Great Britain . This arrangement, however, proved temporary. French power rebounded under the subsequent military leadership of Napoleon Bonaparte, and on October 1, 1800, Napoleon induced a reluctant King Charles IV of Spain to agree, for a consideration, to cede Louisiana back to France. King Charles gave at least his verbal assent on the condition that France would never alienate the territory to a third power. With this treaty of retrocession, known as the Treaty of San Ildefonso (confirmed March 21, 1801), would go not only the growing and commercially significant port of New Orleans but the strategic mouth of the Mississippi River.

Reports of the supposed retrocession soon were received by the U.S. government with deep misgivings. During the preceding 12 years, Americans had streamed westward into the valleys of the Cumberland , Tennessee , and Ohio rivers. The very existence of these new settlers depended on their right to use the Mississippi River freely and to make transshipment of their exports at New Orleans. By terms of the Treaty of San Lorenzo, Spain, in 1795, had granted to the United States the right to ship goods originating in American ports through the mouth of the Mississippi without paying duty and also the right of deposit, or temporary storage, of American goods at New Orleans for transshipment. But in 1802 Spain in effect revoked the right of deposit, and so it was in an atmosphere of growing tension in the West that Pres. Thomas Jefferson was confronted with the prospect of a new, wily, and more powerful keeper of the strategic window to the Gulf of Mexico .

Jefferson instructed Robert R. Livingston , the U.S. minister at Paris , to take two steps: (1) to approach Napoleon’s minister, Charles-Maurice de Talleyrand , with the object of preventing the retrocession in the event this act had not yet been completed; and (2) to try to purchase at least New Orleans if the property had actually been transferred from Spain to France. Direct negotiations with Talleyrand, however, appeared to be all but impossible. For months Livingston had to be content with tantalizing glimmerings of a possible deal between France and the United States. But even these faded as news of the Spanish governor’s revocation of the right of deposit reached the U.S. minister. With this intelligence he had good reasons for thinking the worst: that Napoleon Bonaparte may have been responsible for this unfortunate act and that his next move might be to close the Mississippi River entirely to the Americans. Livingston had but one trump to play, and he played it with a flourish . He made it known that a rapprochement with Great Britain might, after all, best serve the interests of his country, and at that particular moment an Anglo-American rapprochement was about the least of Napoleon’s desires.

There are good reasons to believe that French failure in Santo Domingo (the island of Hispaniola ), the imminence of renewed war with Great Britain, and financial stringencies may all have prompted Napoleon in 1803 to offer for sale to the United States the entire Louisiana Territory. At this juncture, James Monroe arrived in Paris as Jefferson’s minister plenipotentiary; and even though the two American ministers possessed neither instructions nor authority to purchase the whole of Louisiana, the negotiations that followed—with Franƈois, marquis de Barbé-Marbois , minister for the treasury, acting for Napoleon—moved swiftly to a conclusion .

a essay on louisiana purchase

A treaty was signed on May 2 but was antedated to April 30. By its terms the Louisiana Territory, in the form France had received it from Spain, was sold to the United States. For this vast domain the United States agreed to pay $11,250,000 outright and assumed claims of its citizens against France in the amount of $3,750,000. Interest payments incidental to the final settlement made the total price $27,267,622.

a essay on louisiana purchase

Precisely what the United States had purchased was unclear. The wording of the treaty was vague; it did not clearly describe the boundaries. It gave no assurances that West Florida was to be considered a part of Louisiana; neither did it delineate the southwest boundary. The American negotiators were fully aware of this.

But before the United States could establish fixed boundaries to Louisiana there arose a basic question concerning the constitutionality of the purchase. Did the Constitution of the United States provide for an act of this kind? The president, in principle a strict constructionist, thought that an amendment to the Constitution might be required to legalize the transaction; but, after due consideration and considerable oratory, the Senate approved the treaty by a vote of 24 to 7.

The setting of fixed boundaries awaited negotiations with Spain and Great Britain. The exasperating dispute with Spain over the ownership of West Florida and Texas was finally settled by the purchase of the Floridas from Spain in 1819 and the establishment of a fixed southwest boundary line. This line followed the Sabine River from the Gulf of Mexico to the parallel of 32° N; ran thence due north to the Red River , following this stream to the meridian 100° W; thence north to the Arkansas River and along this stream to its source; thence north or south, as the case might be (the source of the Arkansas was not then known), to the parallel of 42° N and west along this line to the Pacific Ocean. The northern boundary was amicably established by an Anglo-American convention in 1818. It established the 49° parallel N between the Lake of the Woods and the Rocky Mountains as the American-Canadian border. The Rocky (then referred to as “Stony”) Mountains were accepted as the western limit of the Louisiana Territory, and the Mississippi River was considered for all practical purposes the eastern boundary of the great purchase. Much of the territory turned out to contain rich mineral resources, productive soil, valuable grazing land, forests, and wildlife resources of inestimable value. Out of this empire were carved in their entirety the states of Louisiana , Missouri , Arkansas , Iowa , North Dakota , South Dakota , Nebraska , and Oklahoma ; in addition, the area included most of the land in Kansas , Colorado , Wyoming , Montana , and Minnesota .

The beginning of the 19 th century was a tumultuous time for the United States. There was ongoing strife within the country and around the country’s borders. The Reigning president at the time was Thomas Jefferson. One of Jefferson’s most significant acts as president was overseeing the Louisiana Purchase. The “Louisiana Purchase is still the largest land deal in the US history as it involved a $15 million price tag in 1803” (Sloane, 2004).

The transacted land amounted to over eight hundred thousand square miles. Jefferson brokered this deal through two of his ambassadors James Monroe and Robert Livingston. The idea to acquire Louisiana was conceived after the New Orleans port fell under Napoleon Bonaparte’s French territory. The port was of great importance to the US trade and its closure necessitated sending ambassadors to France. It was in this mission that Napoleon agreed to sell not only the New Orleans port but also the entire Louisiana territory.

Before the Louisiana Purchase, Jefferson prided himself in being a strict constitutionalist. However, this enormous transaction put a blemish on Jefferson’s record of strict adherence to the constitution. Some people feel that the Louisiana Purchase was conducted within the confines of the United States constitution. This paper will explore the arguments forwarded by both sides of the debate and offer a personal interpretation of the matter.

The argument against Jefferson’s actions is always supported from various angles. Before the transaction was completed, Jefferson expressed fears that it would be deemed unconstitutional. Therefore, he forwarded a constitutional amendment that would eliminate doubts against the constitutionality of the transaction to senate representatives. However, Jefferson received advice against this process because it would take too long and Napoleon could change his mind within this period.

Eventually, Jefferson opted to draw up a constitutional amendment that would give the federal government power to acquire new land on behalf of the people (Les Benedict, 2007). This amendment was ratified by the senate a few months after the Louisiana Purchase was completed. One of the reasons why Jefferson’s actions did not raise a storm in 1803 is because the citizens were pleased with this purchase.

The argument against the constitutionality of the Louisiana Purchase is founded on the fact that the responsibility of acquiring new territory was not defined in the US constitution. The Louisiana Purchase had a huge impact on the US territory because it doubled its size at the time. The people who claim that Jefferson’s actions were unconstitutional argue that the constitution did not give him the right to acquire new territory (Levin & Chen, 2012).

This means that Jefferson’s actions were not defined by any part of the constitution and this makes them unlawful. The issue under contention is the unconstitutional expansion of territory. This is in spite of the fact that Thomas Jefferson did not assume presidency with any territory-expansion agendas. The Louisiana Purchase was just a series of events that ended with territory expansion.

The people who are of the view that Jefferson acted within the constitution when he acquired the Louisiana territory, use the tenth amendment to support their argument. According to the tenth amendment, both states and citizens have the right to carry out any actions that are not disallowed by the constitution.

Jefferson’s actions fall under this category. The people who fault Jefferson’s actions do so using the argument that his actions were not defined by the constitution. However, his actions were not disallowed in the US constitution and they are therefore legitimized by the tenth amendment. The group supporting Jefferson’s actions feels that the constitutionalist’s actions never violated his beloved constitution.

The argument against the Louisiana Purchase constitutionality is pegged on the lack of a constitutional clause that allows governments to increase territory through any means. This argument would be void if the Louisiana Purchase occurred today.

However, the main purpose of the fresh constitution of 1803 was to ensure that the government could not intrude the citizens’ lives. Therefore, expansion of territory could qualify as an intrusion of people’s lives. Jefferson was an avid supporter of this notion. By using these two precedents, it would be easy for anyone to castigate Jefferson.

Nevertheless, constitutionality is not judged by notions but by what is expressed through writing. This means that Jefferson was still shielded by the tenth amendment. The amendment legalizes Jefferson’s actions because the rest of the constitution does not make them illegal. In addition, using the principle of notions, one can argue that the Louisiana Purchase was ‘accidental’. Jefferson’s actions were not pre-planned and therefore he was not taking advantage of the tenth amendment.

Initially, Jefferson had sent two ambassadors to France to negotiate a possible treaty with France. The treaty was supposed to involve the exchange of the Florida territory with the New Orleans port but it eventually became about territory expansion. Jefferson considered this transaction a great opportunity for America and he opted to go ahead with the purchase.

The Louisiana Purchase has led to one of the oldest debates concerning the constitutionality of a president’s actions. Even though both sides of the debate make valid claims, it is clear that no constitutional clauses were violated. This debate is likely to continue mostly because of the significance of Louisiana Purchase in the US history.

Negotiated by the administration of Thomas Jefferson and ratified by Congress on October 20, 1803, the Louisiana Purchase Treaty roughly doubled the size of the United States. An enormous area stretching from the Gulf of Mexico to what is now the Canadian border, the land would ultimately be carved into fifteenth separate states, including Kansas, Nebraska, and Missouri. The addition of new lands opened up conflicts over the disposition of Native people’s claims to land and sovereignty in the territory as well as the issue of slavery.  Whether these new states permitted or prohibited slavery would affect the precarious balance of power between slave state and free state under the original Constitution. The 1820 debates over the admission of Missouri resulted in a “compromise” whereby Missouri would be admitted as a slave state; but all future states carved out of the territory above the 36-30 line would be free. For the next forty years, the nation became increasingly divided over slavery and congressional power to ban slavery in the territories. In Dred Scott v. Sanford , Chief Justice Taney declared that the Missouri Compromise unconstitutionally denied slave owners of their property rights under the Fifth Amendment’s Due Process Clause. The adoption of the Thirteenth Amendment in 1865 ended the question of slavery in the territories. The Fourteenth Amendment transformed the treaty’s protection of the “rights, advantages and immunities of citizens of the United States” into the “privileges or immunities of citizens of the United States” which “no state shall” abridge.
