Alexander Hamilton (1755/57-1804) was a Founding Father of the United States. He is known for his influential role in shaping the nation's financial system and government structure. Born in the Caribbean, he moved to the American colonies and became a key aide to General George Washington during the Revolutionary War. Hamilton was the principal author of the Federalist Papers, which advocated for the ratification of the U.S. Constitution. As the first Secretary of the Treasury, he established the national bank and laid the foundation for the country's economic system. Hamilton's life ended tragically in a duel with Aaron Burr in 1804.
