Jefferson was
sworn in as president by
Chief Justice John Marshall at the new
Capitol in Washington, D.C., on March 4, 1801. His inauguration was not attended by outgoing President Adams. In contrast to his two predecessors, Jefferson exhibited a dislike of formal etiquette. Plainly dressed, he chose to walk alongside friends to the Capitol from his nearby boardinghouse instead of arriving by carriage. His inaugural address struck a note of reconciliation and commitment to democratic ideology, declaring, "We have been called by different names brethren of the same principle. We are all Republicans, we are all Federalists." He said that a free and republican government was "the strongest government on earth". He began dismantling Hamilton's Federalist fiscal system with help from the secretary of the treasury, Albert Gallatin. Gallatin devised a plan to eliminate the national debt in sixteen years by extensive annual appropriations and reduction in taxes. The administration eliminated the whiskey excise and other taxes after closing "unnecessary offices" and cutting "useless establishments and expenses". Jefferson believed that the
First Bank of the United States represented a "most deadly hostility" to republican government. Gallatin argued that the national bank was a useful financial institution and set out to expand its operations. Jefferson looked to other corners to address the growing national debt.
Domestic affairs Jefferson pardoned several of those imprisoned under the Alien and Sedition Acts. Congressional Republicans repealed the
Judiciary Act of 1801, which removed nearly all of Adams's "midnight judges". A subsequent appointment battle led to the Supreme Court's landmark decision in
Marbury v. Madison, asserting judicial review over executive branch actions. Jefferson appointed three
Supreme Court justices:
William Johnson (1804),
Henry Brockholst Livingston (1807), and
Thomas Todd (1807). Jefferson strongly felt the need for a national military university, producing an officer engineering corps for a national defense based on the advancement of the sciences, rather than having to rely on foreign sources. He signed the
Military Peace Establishment Act on March 16, 1802, founding the
United States Military Academy at
West Point. The act documented a new set of laws and limits for the military. Jefferson was also hoping to bring reform to the Executive branch, replacing Federalists and active opponents throughout the officer corps to promote Republican values. Jefferson took great interest in the
Library of Congress, which had been established in 1800. He often recommended books to acquire. In 1802, Congress authorized Jefferson to name the first Librarian of Congress, and formed a committee to establish library regulations. Congress also granted both the president and vice president the right to use the library.
Foreign affairs (1801–1805) First Barbary War of
North Africa in 1806, including (left to right):
Morocco,
Gibraltar,
Tunis, and
Tripoli American merchant ships had been protected from
Barbary Coast pirates by the
Royal Navy when the states were British colonies. After independence, however, pirates often captured U.S. merchant ships, pillaged cargoes, and enslaved or held crew members for ransom. Jefferson had opposed paying tribute to the Barbary States since 1785. In 1801, he authorized a U.S. Navy fleet under Commodore
Richard Dale to make a show of force in the Mediterranean, the first American naval squadron to cross the Atlantic. Following the fleet's first engagement, he successfully asked Congress for a declaration of war.
Pasha of
Tripoli Yusuf Karamanli captured the , so Jefferson authorized
William Eaton, the U.S. Consul to
Tunis, to lead a force to restore the pasha's older brother to the throne. The American navy forced Tunis and Algiers into breaking their alliance with Tripoli. Jefferson ordered five separate naval bombardments of Tripoli, leading the pasha to sign a treaty that restored peace in the Mediterranean. This victory proved only temporary, but according to Wood, "many Americans celebrated it as a vindication of their policy of spreading free trade around the world and as a great victory for liberty over tyranny."
Louisiana Purchase , completed during
Jefferson's presidency, added , which doubled the geographic size of the United States. Spain
ceded ownership of the Louisiana territory in 1800 to France. Jefferson was concerned that
Napoleon's interests in the vast territory would threaten the security of the continent and
Mississippi River shipping. He wrote that the cession "works most sorely on the U.S. It completely reverses all the political relations of the U.S." In 1802, he instructed
James Monroe and
Robert R. Livingston to negotiate the purchase of
New Orleans and adjacent coastal areas. In early 1803, Jefferson offered Napoleon nearly $10 million for of tropical territory. Napoleon realized that French military control was impractical over such a vast remote territory, and he was in dire need of funds for his
wars on the home front. In early April 1803, he unexpectedly made negotiators a counter-offer to sell of French territory for $15 million (~$ in ), doubling the size of the United States. Most thought that this was an exceptional opportunity, despite Republican reservations about the Constitutional authority of the federal government to acquire land. Jefferson initially thought that a Constitutional
amendment was necessary to purchase and govern the new territory; but he later changed his mind, fearing that this would give cause to oppose the purchase, and urged a speedy debate and ratification. On October 20, 1803, the Senate ratified the purchase treaty by a vote of 24–7. Jefferson personally was humble about acquiring the Louisiana Territory, but he resented complainers who called the vast domain a "howling wilderness". After the purchase, Jefferson preserved the region's Spanish legal code and instituted a gradual approach to integrating settlers into American democracy. He believed that a period of the federal rule would be necessary while Louisianans adjusted to their new nation. Historians have differed in their assessments regarding the constitutional implications of the sale, but they typically hail the Louisiana acquisition as a major accomplishment.
Frederick Jackson Turner called the purchase the most formative event in American history. Jefferson and others were influenced by exploration accounts of
Le Page du Pratz in Louisiana (1763) and
James Cook in the Pacific (1784), and they persuaded Congress in 1804 to fund an expedition to explore and
map the newly acquired territory to the Pacific Ocean. Jefferson appointed secretary
Meriwether Lewis and acquaintance
William Clark to lead the
Corps of Discovery (1803–1806). In the months leading up to the expedition, Jefferson tutored Lewis in the sciences of mapping, botany, natural history, mineralogy, and astronomy and navigation, giving him unlimited access to his library at Monticello, which included the largest collection of books in the world on the subject of the geography and natural history of the North American continent, along with an impressive collection of maps. The expedition
lasted from May 1804 to September 1806 and obtained a wealth of scientific and geographic knowledge, including knowledge of many Indian tribes. Jefferson organized three other western expeditions: the
William Dunbar and George Hunter Expedition on the
Ouachita River (1804–1805), the
Thomas Freeman and Peter Custis Expedition (1806) on the
Red River, and the
Zebulon Pike Expedition (1806–1807) into the Rocky Mountains and the Southwest. All three produced valuable information about the American frontier. This interest also motivated Jefferson to meet the Prussian explorer
Alexander von Humboldt several times in June 1804, inquiring into Humboldt's knowledge of New Spain's natural resources, economic prospects, and demographic development.
Native American affairs , leader of the
Shawnee, accepted Jefferson's Indian assimilation policies. Jefferson refuted the contemporary notion that Indians were inferior and maintained that they were equal in body and mind to people of European descent, although he believed them to be inferior in terms of culture and technology. As governor of Virginia during the Revolutionary War, Jefferson recommended moving the
Cherokee and
Shawnee tribes, who had allied with the British, to west of the Mississippi River. But when he took office as president, he quickly took measures to avert another major conflict, as American and Indian societies were in collision and the British were inciting Indian tribes from Canada. In Georgia, he stipulated that the state would release its legal claims for lands to its west in exchange for military support in expelling the Cherokee from Georgia. This facilitated his policy of western expansion, to "advance compactly as we multiply". In keeping with his
Enlightenment thinking, President Jefferson adopted an assimilation policy toward American Indians known as his "civilization program" which included securing peaceful U.S.–Indian treaty alliances and encouraging agriculture. Jefferson advocated that Indian tribes should make federal purchases by credit holding their lands as collateral. Various tribes accepted Jefferson's policies, including the Shawnees led by
Black Hoof, the
Muscogee, and the Cherokee. However, some Shawnees, led by
Tecumseh, broke off from Black Hoof, and opposed Jefferson's assimilation policies. Historian Bernard Sheehan argues that Jefferson believed that assimilation was best for American Indians, and next-best was removal to the west; he felt that the worst outcome of the conflict would be their attacking the whites. Miller agrees that Jefferson believed that Indians should assimilate to American customs and agriculture. Historians such as
Peter S. Onuf and Merrill D. Peterson argue that Jefferson's actual Indian policies did little to promote assimilation and were a pretext to seize lands.
Re-election in 1804 and second term in which Jefferson was reelected overwhelmingly to a second term as president Jefferson was nominated for reelection by the Democratic-Republican Party, with
George Clinton replacing Burr as his running mate. The Federalist Party ran
Charles Cotesworth Pinckney of South Carolina, John Adams's vice presidential candidate in the 1800 election. The Jefferson-Clinton ticket won overwhelmingly in the electoral college vote, by 162 to 14, promoting their achievement of a strong economy, lower taxes, and the Louisiana Purchase. Jefferson's popularity suffered further in his second term as a result of his response to wars in Europe. Relations with Britain deteriorated, due partly to the antipathy between Jefferson and British diplomat
Anthony Merry. After
Napoleon's decisive victory at the
Battle of Austerlitz in 1805, Napoleon became more aggressive in his negotiations with Jefferson and the U.S. over trading rights, which the U.S. proved unsuccessful in countering. Jefferson then led the enactment of the
Embargo Act of 1807, directed at both France and Britain, which triggered economic chaos in the U.S. and was strongly criticized, leading Jefferson to abandon the policy a year later. During the American Revolution, colonial states abolished the international slave trade, but
South Carolina reopened it. In his annual message of December 1806, Jefferson denounced the international slave trade as "violations of human rights" and called on the new Congress to immediately criminalize it. The following year, in 1807, Congress passed the
Act Prohibiting Importation of Slaves, which Jefferson signed. The act established severe punishment against the international slave trade, although it did not address the issue domestically. In
Haiti, Jefferson's neutrality allowed arms to flow to the slave independence movement during the
Haitian Revolution, and Jefferson blocked attempts to assist Napoleon, who was defeated militarily in Haiti in 1803. But Jefferson's administration refused official recognition of Haiti during his second term, in deference to southern complaints about racial violence against slave holders. Recognition was not extended to Haiti until 1862.
Controversies Burr conspiracy and trial by
John Vanderlyn Following the 1801 electoral deadlock, Jefferson's relationship with his vice president,
Aaron Burr, rapidly eroded. Jefferson suspected Burr of seeking the presidency for himself, while Burr was angered by Jefferson's refusal to appoint some of his supporters to federal office. Burr was dropped from the Democratic-Republican ticket in 1804 in favor of charismatic
George Clinton. The same year, Burr was soundly defeated in his bid to be elected
New York governor. During the campaign,
Alexander Hamilton made publicly callous remarks regarding Burr's moral character.
Burr challenged Hamilton to a duel, held on July 11, 1804. In the duel, Burr mortally wounded Hamilton, who died the following day. Burr was subsequently indicted for Hamilton's murder, causing him to flee to
Georgia, even though he remained president of the
U.S. Senate during Supreme Court Justice
Samuel Chase's
impeachment trial. Both indictments quietly died and Burr was not prosecuted. In August 1804, Burr contacted British Minister
Anthony Merry offering to cede U.S. western territory in return for money and British ships. After leaving office in April 1805, Burr traveled west and conspired with Louisiana Territory governor
James Wilkinson, beginning a large-scale recruitment for a military expedition. Burr discussed seizing control of Mexico or Spanish Florida, or forming a secessionist state in New Orleans or the Western U.S.; historians remain unclear as to his true goal. In the fall of 1806, Burr launched a military flotilla carrying about 60 men down the
Ohio River. Wilkinson renounced the plot and reported Burr's expedition to Jefferson, who ordered Burr's arrest. On February 13, 1807, Burr was captured in Louisiana and sent to Virginia to be tried for treason. Jefferson attempted to preemptively influence the verdict by telling Congress that Burr's guilt was "beyond question", but the case came before his longtime political foe, and distant cousin,
John Marshall, who dismissed the treason charge. Burr's legal team subpoenaed Jefferson, but Jefferson refused to testify, making the first argument for
executive privilege. Instead, Jefferson provided relevant legal documents. After a three-month trial, the jury found Burr not guilty, while Jefferson denounced his acquittal. Jefferson subsequently removed Wilkinson as territorial governor but retained him in the U.S. military. Historian James N. Banner criticized Jefferson for continuing to trust Wilkinson, a "faithless plotter".
Wilkinson's misconduct Commanding General
James Wilkinson was a holdover of the Washington and Adams administrations. In 1804, Wilkinson received 12,000 pesos from the Spanish for information on American boundary plans. Wilkinson also received advances on his salary and payments on claims submitted to Secretary of War
Henry Dearborn. This damaging information apparently was unknown to Jefferson. In 1805, Jefferson trusted Wilkinson and appointed him Louisiana Territory governor, admiring Wilkinson's work ethic. In January 1806, Jefferson received information from Kentucky U.S. Attorney Joseph Davies that Wilkinson was on the Spanish payroll. Jefferson took no action against Wilkinson, since there was not then significant evidence against him. An investigation by the
U.S. House of Representatives in December 1807 exonerated Wilkinson. In 1808, a military court looked into the allegations against Wilkinson but also found a lack of evidence. Jefferson retained Wilkinson in the
U.S. Army. Evidence found in Spanish archives in the 20th century proved Wilkinson was on the Spanish payroll.
Foreign affairs (1805–1809) Attempted annexation of Florida In the aftermath of the
Louisiana Purchase, Jefferson attempted to annex
West Florida from Spain. In his annual message to Congress, on December 3, 1805, Jefferson railed against Spain over Florida border depredations. A few days later Jefferson secretly requested a two-million-dollar expenditure to purchase Florida. Floor leader
John Randolph opposed annexation, was upset over Jefferson's secrecy on the matter, and believed the money would end up going to Napoleon. The British warship
encountered the off the Virginia coast in June 1807;
Leopard fired at
Chesapeake after the latter refused to allow for a search for deserters before removing four deserters from the ship. Jefferson issued a proclamation banning British warships from U.S. waters. He presumed unilateral authority to call on the states to prepare 100,000 militia and ordered the purchase of arms, ammunition, and supplies, writing, "The laws of necessity, of self-preservation, of saving our country when in danger, are of higher obligation [than strict observance of written laws]". The was dispatched to demand an explanation from the
British government, and Jefferson called for a special session of Congress in October to enact an embargo or alternatively to consider war.
Embargo (1807–1809) , depicting merchants dodging the "Ograbme", which is "Embargo" spelled backward In December 1807, news arrived that Napoleon had extended the
Berlin Decree, globally banning British imports. The Royal Navy, meanwhile continued to impress sailors from American merchant ships. However, Congress had no appetite to prepare the U.S. for war; Jefferson asked for and received the Embargo Act, an alternative that allowed the U.S. more time to build up defensive works, militias, and naval forces. Meacham argued that the
Embargo Act was a projection of power that surpassed the Alien and Sedition Acts, and R. B. Bernstein said that Jefferson "was pursuing policies resembling those he had cited in 1776 as grounds for independence and revolution". In November 1807, Jefferson, for several days, met with his cabinet to discuss the deteriorating foreign situation. Secretary of State James Madison supported the embargo, while Treasury Secretary Gallatin opposed it, due to its indefinite time frame and the risk to the policy of American neutrality. The U.S. economy suffered, criticism grew, and opponents began evading the embargo. Instead of retreating, Jefferson sent federal agents to secretly track down smugglers and violators. Three acts were passed in Congress during 1807 and 1808, called the
Supplementary, the
Additional, and the
Enforcement acts. Shortly before leaving office in March 1809, Jefferson signed the repeal of the Embargo. In its place, the
Non-Intercourse Act was passed, but it proved no more effective.
