The Twelfth Amendment to the United States Constitution provides the procedure for electing the president and vice president. It replaced the procedure in Article II, Section 1, Clause 3, under which the Electoral College originally functioned. The amendment was proposed by Congress on December 9, 1803, and was ratified by the requisite three-fourths of state legislatures on June 15, 1804. The new rules took effect for the 1804 presidential election and have governed all subsequent presidential elections.
The 1792 United States presidential election was the second quadrennial presidential election. It was held from Friday, November 2, to Wednesday, December 5, 1792.

The 1800 United States presidential election was the fourth quadrennial presidential election. It was held from Friday, October 31 to Wednesday, December 3, 1800. In what is sometimes called the "Revolution of 1800", the Democratic-Republican Party candidate, Vice President Thomas Jefferson, defeated the Federalist Party candidate and incumbent, President John Adams. The election was a political realignment that ushered in a generation of Democratic-Republican leadership. This was the first presidential election in American history to be a rematch.

The 1812 United States presidential election was the seventh quadrennial presidential election. It was held from Friday, October 30, 1812, to Wednesday, December 2, 1812. Taking place in the shadow of the War of 1812, incumbent Democratic-Republican President James Madison defeated DeWitt Clinton, the lieutenant governor of New York and mayor of New York City, who drew support from dissident Democratic-Republicans in the North as well as Federalists.

The 1816 United States presidential election was the eighth quadrennial presidential election. It was held from Friday, November 1 to Wednesday, December 4, 1816.

The election was the last in which the Federalist Party fielded a presidential candidate.
The 1820 United States presidential election was the ninth quadrennial presidential election. It was held from Wednesday, November 1, to Wednesday, December 6, 1820. Taking place at the height of the Era of Good Feelings, the election saw incumbent Democratic-Republican President James Monroe win re-election without a major opponent. It was the third and the most recent United States presidential election in which a presidential candidate ran effectively unopposed. As of 2024, this is the most recent presidential election where an incumbent president was re-elected who was neither a Democrat nor a Republican, before the Democratic-Republican party split into separate parties. James Monroe's re-election marked the first time in U.S. history that a third consecutive president won a second election. This happened again with Barack Obama's re-election in the 2012 election and at no other point have multiple consecutive presidents won two elections. Monroe is also the first candidate to receive over 200 electoral votes for president.
The election of the president and the vice president of the United States is an indirect election in which citizens of the United States who are registered to vote in one of the fifty U.S. states or in Washington, D.C., cast ballots not directly for those offices, but instead for members of the Electoral College. These electors then cast direct votes, known as electoral votes, for president, and for vice president. The candidate who receives an absolute majority of electoral votes is then elected to that office. If no candidate receives an absolute majority of the votes for president, the House of Representatives elects the president; likewise if no one receives an absolute majority of the votes for vice president, then the Senate elects the vice president.
