Aaron Burr was an American politician and lawyer who served as the third Vice President of the United States from 1801 to 1805 under Thomas Jefferson. He is best known for his duel with Alexander Hamilton in 1804, which resulted in Hamilton's death and significantly tarnished Burr's reputation. Born in 1756, Burr was a prominent figure in early American politics and played a role in the Revolutionary War. After his vice presidency, he faced legal challenges and was tried for treason in 1807, though he was acquitted. Burr's life remains a subject of interest in American history.
