The election of 1800, often referred to as the "Revolution of 1800," was a significant milestone in American political history. It was primarily decided by the House of Representatives due to a tie in the Electoral College.
In the election, Thomas Jefferson, a Democratic-Republican, and John Adams, a Federalist, were the main candidates. Jefferson and his running mate, Aaron Burr, received the same number of electoral votes—73. Adams received 65 votes, while his running mate, Charles Cotesworth Pinckney, received 64 votes. According to the original provisions of the Constitution, this tie forced the election into the House of Representatives, where each state delegation cast one vote for one of the tied candidates.
In February 1801, the House convened to break the tie. After multiple ballots and significant political maneuvering, Jefferson was ultimately elected President on the 36th ballot. This election was notable not only because of the tie but also because it represented a peaceful transfer of power between rival political parties, which was seen as a vital element of the democratic process.
The outcome of the election led to significant changes in American politics, including the eventual passage of the 12th Amendment in 1804, which established separate electoral votes for President and Vice President to prevent future ties of this nature.
