Aaron Burr: Jefferson's running mate during the 1800 election.
John Marshall: Chief Justice of the Supreme Court who established judicial review.

The expedition began in 1804 and traveled from St. Louis to the Pacific Ocean, significantly charting unexplored territory.
The expedition is regarded as one of Jefferson's great achievements.

Election Campaign: Bitter contest between Thomas Jefferson (Democratic-Republican) and John Adams (Federalist).
Jefferson won by eight electoral votes but faced a deadlock with his running mate Aaron Burr, leading to intervention by Alexander Hamilton to break the tie.
Resulted in the passage of the Twelfth Amendment to prevent future electoral deadlocks.

Jefferson aimed for a “peaceful revolution” to restore republican ideals.
He replaced Federalist officials with Democratic-Republicans to balance the government.
Jefferson introduced a simpler government, symbolized by walking to his inauguration.
He believed in decentralizing power, reducing military size, halting naval expansion, and eliminating internal taxes.

The location of the new federal capital in Washington, D.C. showcased the growing political influence of the Southern states.
Jefferson was the first president from the South, followed by Madison and Monroe, emphasizing Southern political dominance.

Following the election loss, Aaron Burr challenged Alexander Hamilton to a duel after Hamilton criticized him.
Burr shot Hamilton, leading to Hamilton's death and Burr fleeing to evade murder charges.

Despite the political shift, Federalists maintained influence in the judicial branch, particularly through Chief Justice John Marshall.
Judiciary Act of 1801: Expanded federal judgeships filled with Federalists, which angered Jefferson and his party.

A pivotal court case regarding William Marbury, a midnight judge whose appointment was disputed.
Chief Justice Marshall ruled that the Supreme Court could declare acts of Congress unconstitutional, affirming the principle of judicial review.

During Jefferson’s presidency, westward migration continued, exemplified by population growth in Ohio.
Pioneer Life: Hardships faced by settlers reflected in Michaux's writings on their living conditions.

In 1800, Spanish territory reverted back to France under Napoleon, raising U.S. concerns about France's presence.
Jefferson sent diplomats to purchase New Orleans and Florida but ended up acquiring the entire Louisiana Territory for $15 million.
This more than doubled the size of the United States, despite Jefferson's initial concerns about the constitutional authority to acquire new territory.

Appointed by Jefferson, Meriwether Lewis and William Clark led the Corps of Discovery to explore the newly acquired territory.
The expedition lasted over two years, yielding crucial information about the geographical and cultural aspects of the region.

The expansion and establishment of judicial review fundamentally shaped the political landscape of the U.S., impacting future governance and territorial ambitions.
