Alexander Hamilton (c. 11 January 1755 or 1757 - 12 July 1804) was an American statesman, lawyer, military officer, and political theorist who served as the first Secretary of the Treasury of the United States under President George Washington. Born on the island of Nevis in the British West Indies, Hamilton emigrated to the American colonies in 1772, studied at King's College (now Columbia University) in New York, and rose to prominence as an aide-de-camp to General George Washington during the Revolutionary War. He was a principal author of The Federalist Papers (writing 51 of the 85 essays), a co-founder of the Federalist Party, the founder of the U.S. Coast Guard, and the architect of the early American financial system. He died on 12 July 1804 from wounds sustained in a duel with Vice President Aaron Burr the previous day.

Hamilton's birth year is disputed - some historians cite 1755, others 1757 - and his early life was marked by instability. His parents were never married; his father, James Hamilton, a Scottish merchant of minor nobility, abandoned the family, and his mother, Rachel Faucette, died in 1768. Hamilton was taken in by a merchant cousin, Peter Lytton, who later took his own life, after which Hamilton was apprenticed to a trading firm. His evident intellectual ability attracted the notice of local patrons who financed his education in the colonies. See Alexander Hamilton - History for a fuller account of his life and career.

Hamilton's most consequential work came during and after the Constitutional Convention of 1787. He was a delegate from New York, though his two fellow delegates were Anti-Federalists and frequently outvoted him within the state delegation. Hamilton co-authored The Federalist Papers (1787-1788) with James Madison and John Jay, producing 51 of the 85 essays under the pseudonym “Publius.” These essays argued for ratification of the proposed Constitution and remain a primary source for constitutional interpretation.

As Treasury Secretary (1789-1795), Hamilton proposed and largely achieved a financial program that included federal assumption of state Revolutionary War debts, establishment of the First Bank of the United States, creation of a national mint, and a system of tariffs and excise taxes to fund federal operations. His Report on Manufactures (1791) argued for active federal encouragement of domestic industry, a position that became foundational to later American industrial policy. These measures were contested at the time and remain subjects of ongoing historical and policy debate.

Hamilton's relationship with Thomas Jefferson and James Madison deteriorated sharply over fiscal and constitutional philosophy, producing the first recognizable party division in American national politics - Federalists versus Democratic-Republicans. His opposition to Aaron Burr's political ambitions, expressed across multiple election cycles, culminated in the 1804 duel in Weehawken, New Jersey, in which Hamilton was mortally wounded. Whether Hamilton intentionally withheld or misdirected his fire is a matter of historical debate.

Hamilton's legacy has been contested across several dimensions. His vision of federal power - broad, energetic, and favorable to commercial and manufacturing interests - placed him in direct conflict with the Jeffersonian model of limited government and agrarian republicanism. Scholars disagree about the long-term effects of his financial system, his views on democracy and popular government, the degree to which his policies favored elite financial interests, and his relationship to slavery (he expressed antislavery sentiment but his in-laws, the Schuyler family, were slaveholders, and scholars have debated the extent to which Hamilton facilitated or accommodated slaveholding arrangements). His reputation has undergone significant revision across different historical eras, with a notable popular resurgence following the 2015 Broadway musical Hamilton.

There is broad scholarly consensus on the basic biographical facts of Hamilton's life and on his central role in shaping early American fiscal and constitutional architecture. The interpretation of his legacy - whether his consolidationist vision was beneficial or harmful, democratic or oligarchic - remains actively debated. See Alexander Hamilton - Historical Consensus.

• Nationalist/Federalist: Hamilton's program built the institutional foundations necessary for American economic growth and national cohesion. Viewpoint: Nationalist-Federalist-viewpoint
• Jeffersonian/Republican: Hamilton's policies centralized power unconstitutionally, enriched financial elites at public expense, and threatened republican self-government. Viewpoint: Jeffersonian-Republican-viewpoint
• Progressive/Left: Hamilton represented the interests of merchants and creditors over ordinary workers and debtors, and his legacy reflects the class interests embedded in the founding order. Viewpoint: Progressive-Left-viewpoint
• Libertarian: Hamilton's broad construction of federal power and his advocacy for a national bank and protective tariffs set precedents for government overreach inconsistent with limited constitutional government. Viewpoint: Libertarian-viewpoint
• Conservative Nationalist: Hamilton's pragmatic statecraft and synthesis of commercial dynamism with strong national institutions offers a model for American conservatism distinct from both libertarianism and progressivism. Viewpoint: Conservative Nationalist-viewpoint
• Antislavery/Abolitionist: Hamilton's expressed opposition to slavery must be weighed against his family connections to slaveholding wealth and questions about his practical accommodation of the institution. Viewpoint: Antislavery/Abolitionist-viewpoint
