Alexander Hamilton (1755-1804) was one of the Founding Fathers of the United States. He served as the country's first Secretary of the Treasury under President George Washington, with whom he had fought during the Revolutionary War. During his term of office, Hamilton established a national bank and tariff system for the new nation. He also launched the New York Post newspaper, the United States Coast Guard and the Federalist Party. Hamilton advocated a stronger role for the federal government, and was an active participant in discussions regarding the new US Constitution. He was the major contributor to the 'Federalist Papers', which today are the most important reference for constitutional interpretation.
