Jefferson first defeated incumbent President John Adams, then bested Aaron Burr after 36 votes in Congress
Why Thomas Jefferson tried to impeach George Washington
Thomas Jefferson was elected the third president of the United States, following a deeply divisive race against John Adams that threatened to tear apart the young nation, on this day in history, Feb. 17, 1801.
It was the first American presidential race pitting party rivals — Federalist Adams vs. Democratic-Republican Jefferson — and the first to unseat a sitting president.
"By early 1799, both parties, Republican and Federalist, were convinced of the other's determination to subvert the government and overthrow the Constitution," writes Thomas Jefferson’s Monticello in its online account of the election.
The election was underscored by shocking accusations of defective ballots, politically partisan media, even ominous threats of civil war – proving that little has changed in American presidential politics in more than 200 years.
Jefferson himself dubbed the election "The Revolution of 1800."

Jefferson became chief executive over party ally Aaron Burr only after an incredible 36 votes in the House of Representatives that followed the general election.

Thousands of people reportedly gathered in the streets of Washington, D.C., as the political drama mounted in Congress, with Federalists seeking ways to block a Jefferson presidency.
The Virginian was inaugurated president, with Burr his vice president, on March 4.

Just three years later Burr, in 1804, the sitting vice president of the United States, famously shot and killed political rival and Adams ally Alexander Hamilton in a duel that appeared to portent a tragic trajectory ahead for the United States.
Hamilton had written earlier that the election of 1800 was a contest to save the new nation from "the fangs of Jefferson."
Said Smithsonian Magazine in 2004 of the election, "Only a quarter of a century after the signing of the Declaration of Independence, the first election of the new 19th century was carried out in an era of intensely emotional partisanship among a people deeply divided over the scope of the government’s authority."

President George Washington had warned against the corrosive potential of rising political factions during his farewell address in September 1796.
"However [political parties] may now and then answer popular ends, they are likely in the course of time and things, to become potent engines, by which cunning, ambitious, and unprincipled men will be enabled to subvert the power of the people," Washington said.
It took just one election cycle for party politics to tear apart the Founding Fathers.

They gave the world the Declaration of Independence, inspired hopes of freedom around the world and reshaped people's relation to government for the better.
Yet they proved ferocious enemies in the new nation.
"A civil war, or a surrender of independence is not more than a twelvemonth's distance," Federalist William Cobbett, under the pseudonym Peter Porcupine, wrote ominously as divisiveness grew during the Adams presidency of the late 1790s.

Voters quarreled over party lines, most notably differences over the French Revolution, America's quasi-war with France, and Adams’s Alien and Sedition Acts — widely perceived by historians as a black mark on the otherwise incredible legacy and brilliant political mind of Adams.
American voters were also regionally divided.
New Englanders supported Adams and the Federalists.
Southerners supported Jefferson and the Democratic-Republicans. The mid-Atlantic States were divided — what we now might call "purple states."
Yet the American people overcame the divide.
Jefferson succeeded Adams as president, marking the first of many peaceful transfers of power between the parties in the United States — and among the very first in human history.

Jefferson and Adams became friends again in their later years, their friendship cemented by voluminous mail correspondence in which both reflected on their incredible role in forging the new nation.

By the 20th century, their vision of a representative constitutional republic — a revolutionary concept in the 1700s — had become the world standard of governance.
"Time had allowed partisan and ideological passions to recede and a friendship that was forged in the crucible of war was rekindled through the quill," writes the Adams National Historical Park.
Both men died on the same day, July 4, 1826 — 50 years to the day after pledging their "lives, fortunes and sacred honor" together in the Declaration of Independence.
"We can no longer say there is nothing new under the sun, for this whole chapter in the history of man is new," Jefferson wrote after his election. "The momentous crisis which lately arose, really bespeak a strength of character in our nation which augurs well for the duration of our republic."
