The Election of 1800
The first transfer of power between rival parties
October 1800 – February 17, 1801Nationwide; decided in the House of Representatives, Washington, D.C.

In 1800 the Democratic-Republicans under Thomas Jefferson defeated President John Adams and the Federalists in a bitter campaign fought largely in partisan newspapers. A flaw in the Constitution produced a tie between Jefferson and his own running mate, Aaron Burr, throwing the decision to the House of Representatives, which deadlocked through thirty-five ballots before choosing Jefferson. The result was the first peaceful transfer of power from one party to another in the United States.

Why it matters
The election of 1800 established that an American government could be voted out and would leave — the foundation of the peaceful transfer of power.
Historical background
By 1800 the country was divided between two parties. Federalists, led by Adams and Alexander Hamilton, favored a strong national government, commercial development, and good relations with Britain. Democratic-Republicans, led by Jefferson and James Madison, championed states’ rights, farmers, and sympathy for France. Adams’s administration had grown unpopular after the Alien and Sedition Acts, a direct tax in 1798, military preparations for a possible war with France, and the use of troops against Fries’s Rebellion in Pennsylvania.
Causes and contributing factors
The Federalists were also split. Many opposed Adams for making peace with France rather than declaring war. Hamilton wrote a letter attacking Adams’s character that was leaked to the press. To carry the crucial state of New York, the Republicans put Aaron Burr of New York on the ticket with Jefferson.
What happened
The campaign was waged through party newspapers and pamphlets, with each side accusing the other of threatening the republic. When the electoral votes came in, Jefferson and Burr each had 73. Under the original Constitution, each elector cast two votes without distinguishing between president and vice president, so the tie between the two Republicans sent the election to the House, where the Federalists held a majority. For days the House deadlocked. Through thirty-five ballots, no candidate won a majority of state delegations. Hamilton, who despised Burr as unprincipled, persuaded some Federalists to cast blank ballots rather than support either man, and Jefferson was finally elected.
Immediate consequences
Jefferson took office in March 1801 and, in his inaugural address, called for unity: “We are all Republicans, we are all Federalists.” Before leaving, Adams and the outgoing Federalist Congress expanded the federal judiciary and filled it with Federalist judges, setting up the conflict that produced Marbury v. Madison. Hamilton’s role in Burr’s defeat deepened the feud that ended in their 1804 duel.
Long-term significance
Jefferson later called his victory “the revolution of 1800.” Whatever its revolutionary character, the election showed that power could pass peacefully between bitterly opposed parties under the Constitution — a precedent that later generations would rely on. The Twelfth Amendment, ratified in 1804, changed the Electoral College so that electors vote separately for president and vice president.
