Alexander Hamilton (1755/1757-1804) was a founding father of the United States and the first Secretary of the Treasury. He played a pivotal role in establishing the nation's financial system and was a leader in seeking a stronger federal government. However, he had a long-standing rivalry with Aaron Burr that culminated in a 1804 duel where Burr fatally shot Hamilton. Hamilton made major contributions in his roles in Washington's administration and as a writer of the Federalist Papers, but his death in the duel with Burr weakened the Federalist party and ended his political career.
