After a 73-73 tie in the Electoral College between Thomas Jefferson and Aaron Burr, the Federalist-controlled House of Representatives required 36 ballots over five days to elect Jefferson as the third U.S. president.

Summary

In the bitterly contested 1800 presidential election, Thomas Jefferson and Aaron Burr, both Democratic-Republicans, tied in the Electoral College with 73 votes each, throwing the decision to the outgoing Federalist-controlled House of Representatives. Partisan divisions ran deep, with Federalists initially favoring Burr over Jefferson despite Alexander Hamilton's influential preference for Jefferson as the lesser evil. After 35 inconclusive ballots, on the 36th ballot on February 17, 1801, Jefferson secured the required majority of state delegations. The process highlighted flaws in the original constitutional mechanism for electing presidents and vice presidents. Jefferson's victory ensured the first peaceful transfer of power between opposing political parties in U.S. history.

Context

By 1800, the young republic had developed sharp partisan divisions between the Federalists, who favored a strong central government, closer ties to Britain, and policies supporting commerce and industry, and the Democratic-Republicans, who advocated limited federal power, states’ rights, and an agrarian economy. These differences intensified after George Washington’s retirement, as the 1796 election pitted Federalist John Adams against Democratic-Republican Thomas Jefferson in a contest marked by personal attacks and ideological clashes over the French Revolution and foreign policy.

What Happened

In the 1800 election, Jefferson and his running mate Aaron Burr each received 73 electoral votes, while Adams received 65. Because the Constitution required electors to cast two undifferentiated votes for president and vice president, the tie sent the decision to the outgoing Federalist-dominated House of Representatives. Over five days in February 1801, the House conducted 35 inconclusive ballots, with many Federalists initially preferring Burr, whom they viewed as less threatening than Jefferson despite Alexander Hamilton’s private counsel that Burr was the more dangerous choice.

Aftermath

On the 36th ballot on February 17, ten state delegations supported Jefferson, four backed Burr, and two cast blank ballots, giving Jefferson the required majority. He was inaugurated on March 4, 1801, in a ceremony that included a military escort reflecting lingering tensions, yet proceeded without violence. Burr assumed the vice presidency, and the episode prompted Congress to propose the 12th Amendment, ratified in 1804, which required separate ballots for president and vice president.

Legacy

The resolution of the 1800 crisis established the first peaceful transfer of executive power between opposing political parties in American history, demonstrating the Constitution’s capacity to manage intense partisanship. Historians regard the election as a foundational precedent for democratic stability, while the 12th Amendment permanently addressed the structural flaw that had produced the deadlock.

Why It Matters

The 1800 election crisis prompted the swift adoption of the 12th Amendment in 1804, separating presidential and vice-presidential ballots to prevent future ties. It demonstrated the resilience of the constitutional system amid intense partisanship and set a precedent for orderly power transitions that has endured for over two centuries.
