Thomas Jefferson - Marbury v. Madison Decided

On February 24, 1803, the Supreme Court of the United States issued its unanimous ruling in Marbury v. Madison, one of the most important Supreme Court cases in early American history. This ruling established for the first time the principle that the Supreme Court can declare an act of Congress void if it is inconsistent with the Constitution. This landmark case established the basis for judicial review of congressional and executive actions on the grounds of their constitutionality.

 

Thomas Jefferson's election as President in 1800 came after a bitter partisan struggle between Federalists and Republicans. Republicans won both the presidency and a majority in Congress. Before leaving early in 1801, the Federalist Congress passed a new Judiciary Act that created new judgeships, which enabled outgoing President John Adams to appoint numerous additional Federalists to the judiciary. On his last day in office, Adams worked late into the night signing commissions for new judgeships.

When President Jefferson took over in March 1801, he ordered Secretary of State James Madison not to deliver the commissions. William Marbury, an appointee as a justice of the peace in Washington, sued in the Supreme Court for a writ of mandamus, or a formal order of delivery, that would compel Madison to deliver his commission. Under the 1789 Judiciary Act that instructed the Court to issue writs to government officials in such cases, Chief Justice John Marshall issued a preliminary writ. Madison ignored the writ as judicial interference with the executive branch. Marshall, an arch-Federalist, was eager to oppose Jefferson's administration but knew he could not force its submission, and wanted to assert the power of the judicial branch.

In 1803, Judge Marshall issued a clever ruling, noting that Marbury had a right to his commission, but explaining that the Supreme Court had no jurisdiction in the matter. Because the Constitution did not explicitly grant the Court power to issue writs to government officials, the Judiciary Act of 1789 was unconstitutional. Recognizing the importance of separation of powers, however, he allowed that certain political actions of the executive fell beyond court jurisdiction.

In Marbury v. Madison, the Supreme Court for the first time declared an act of Congress unconstitutional; it would not do so again until the infamous Dred Scott case in 1857. Technically, Marshall let Jefferson win the battle and protected some executive action from judicial review. His ruling announced in ringing terms, however, that the Supreme Court would assume the role of guardian of the Constitution and the nation's laws, providing a forceful check on Congress.

February 24, 1803

Thomas Jefferson - Louisiana Purchase Treaty Signed

On April 30, 1803, representatives from the United States and France signed the Louisiana Purchase Treaty. The terms of the agreement gave all of the Louisiana territory from the Mississippi River to the Rocky Mountains to the United States. The Louisiana Purchase doubled the size of the United States and is considered one of President Thomas Jefferson's greatest presidential accomplishments.

In 1800, President Jefferson learned that Spain had secretly ceded Louisiana to France, and he was concerned about France attempting to reclaim its North American empire. Jefferson wanted to insure that American farmers in the Ohio River Valley had access to the Gulf of Mexico via the Mississippi River–the river was a key to the farmers' economic well-being.

In the spring of 1803, the President sent James Monroe to France to join the French minister, Robert Livingston. He instructed Monroe and Livingston to negotiate the purchase of the city of New Orleans and all or part of Florida from France for $10 million. Monroe arrived just as Napoleon I of France faced renewed war with Britain. In need of money and eager to rid himself of the hassles of governing distant lands after the successful revolt of Saint-Domingue (present-day Haiti), Napoleon offered the entire Louisiana territory to the astonished ministers. Exceeding their instructions, Monroe and Livingston agreed to pay $15 million for the whole territory. The price of $15 million amounted to approximately four cents per acre for 828,000 square miles.

Delighted with the deal but troubled because the Constitution did not specifically provide for the acquisition of new territory, Jefferson considered a constitutional amendment to allow the purchase. Napoleon threatened to withdraw the deal if not soon ratified, however, and so Jefferson sent the treaty to the Senate for approval. Federalists were furious at Jefferson's seeming hypocrisy, as he had long criticized them for not strictly interpreting the Constitution.

The constitutional dilemma for the President was substantial. While believing that the United States must expand to fulfill its republican destiny, he was the first to assert the Constitution did not authorize acquiring new territory. As would be the case in numerous issues during his presidency, Jefferson was forced seek a balance between sometimes conflicting principles. In this case, President Jefferson chose expediency and national interest when he submitted the Louisiana Purchase Treaty to the Senate. The Senate ratified the treaty in October 1803.

Thomas Jefferson - Burr Kills Hamilton in Duel

On July 11, 1804, Aaron Burr and Alexander Hamilton met for duel, and Burr shot and fatally wounded Hamilton, who died the next day. The Burr-Hamilton duel stands as a vivid example that in the early republic partisan politics were also highly personal politics.

Hamilton and Burr had been political adversaries long before their famous duel. Hamilton, an arch-Federalist and President George Washington's secretary of the Treasury strongly distrusted his fellow New Yorker, and he worked against Federalist efforts to elect Burr over Thomas Jefferson, both Republicans, when they tied in the presidential election of 1800. Burr had served various positions in New York politics and then became Jefferson's vice president in 1801. Republicans felt he was unreliable, however, and dropped him in the next election.

In 1804, Burr was running for governor of New York, and Hamilton was leading the opposition to Burr's candidacy; he spoke out against him and questioned his integrity in public. For these slights, Burr challenged Hamilton to a duel. Perceiving that not responding to the challenge would destroy his own honor and render him useless in future political service, Hamilton answered Burr. Although in this era duels were usually avoided by a series of negotiations through which both parties could restore their reputations, Burr took further offense at Hamilton's response. After about ten days of correspondence, Burr and Hamilton met on July 11, 1804, in New Jersey (New York had outlawed dueling).

Hamilton had declared the previous evening his intention to fire into the air; whether or not he shot at Burr remained a point of contention for years to follow, but Burr nonetheless escaped unscathed after fatally wounding Hamilton, who died the next day. After New York and New Jersey both issued warrants for his arrest, Burr went back to the District of Columbia and resumed his position as vice president, presiding over the Senate.

As public outrage grew, Burr fled to the west, where from 1805 to 1807 he participated in a vague but ambitious plan to separate the southwest from the United States. The Supreme Court found him not guilty of treason in 1807, and after five years in Europe, Burr returned to New York, where he practiced law in New York until his death in 1836.

Thomas Jefferson - Lewis and Clark Expedition Arrives Back in St. Louis

On September 23, 1806, Meriwether Lewis and William Clark arrived back in St. Louis two-and-a-half years after they began their expedition to explore the Louisiana Territory and the Pacific Northwest. President Thomas Jefferson commissioned the expedition, which is often considered one of the greatest exploratory quests in U.S. history.

Well before President Jefferson purchased the Louisiana Territory from France, Americans had been curious about the lands west of the Mississippi River. Jefferson saw the West as a great collection of scientific specimens and a vast expanse that enhanced American security, but he also shared the commercial interest of American traders looking for a viable route to the Pacific Ocean. Even before negotiations to purchase New Orleans had commenced, Jefferson planned an expedition to the Pacific Northwest.

In January 1803, the President asked Congress for a secret appropriation of $2,500 for the secretly planned exploration. Despite Spain’s displeasure at U.S. hints that it would trek into French and Spanish territory, Jefferson appointed Meriwether Lewis and William Clark to lead the expedition. Lewis, the President’s personal secretary, was merely 28 years old but had extensive knowledge of the West. He was commissioned an Army officer and given joint command with William Clark, also an Army officer. Jefferson instructed Lewis and Clark to find a path to the Pacific Ocean, preferably via water, learn the geography of the territory, explore trade with Native Americans, and return with samples of unknown species of flora and fauna. His instructions, drafted in June 1803 before the purchase of Louisiana but with knowledge the transaction would likely occur, were implemented the following year.

Lewis and Clark left St. Louis on the Missouri River in May 1804 with a company of nearly fifty men. The Corps of Discovery voyaged up the Missouri to North Dakota, where they spent the winter before pushing on over the Rocky Mountains to the Columbia River and Pacific Ocean. When they returned to St. Louis in September 1806, they brought samples of plant and animal species Jefferson had requested and reports that Jefferson's purchase had been well worth the price.
