(February 6, 1756 – September 14, 1836) was an American politician and lawyer.
He was the third vice president of the United States (1801–1805), serving during President Thomas Jefferson's first term.
Burr served as a Continental Army officer in the American Revolutionary War, after which he became a successful lawyer and politician.
He was elected twice to the New York State Assembly (1784–1785, 1798–1799), was appointed New York State Attorney General (1789–1791), was chosen as a U.S.
senator (1791–1797) from the State of New York, and reached the apex of his career as vice president.
In the waning months of his tenure as president of the Senate, he oversaw the 1805 impeachment trial of Supreme Court Justice Samuel Chase.
As campaign manager for the Democratic-Republican party during the presidential election of 1800, Burr (along with his unofficial campaign team, known as the Little Band) was responsible for the first open, public political campaign.Burr shot his political rival Alexander Hamilton in an 1804 duel, during the last full year of his single term as vice president.
He was never tried for the illegal duel and all charges against him were eventually dropped, but Hamilton's death ended Burr's political career.
Burr left Washington, D.C., and traveled west seeking new opportunies, both economic and political—as well as refuge from the controversy surrounding him in the rest of the country.
His activities eventually led to his arrest on charges of treason in 1807.
He was tried and acquitted multiple times, but the fallout left him with large debts and few influential friends.
To avoid vigilante execution and further charges by the state, he left the United States for Europe.
He remained overseas until 1812, when he returned to the United States to practice law in New York City.
He spent the rest of his life there in relative obscurity.
