How Old Was Alexander Hamilton When He Died? Age & Story (2026)

The Short Answer: About 49

Alexander Hamilton was about 49 years old when he died. He was born on January 11, 1755 — though his birth year is disputed, with some historians arguing for 1757, which would have made him 47. He died on July 12, 1804, from a gunshot wound suffered the previous morning in a duel with Aaron Burr, the sitting vice president of the United States.

Hamilton's age at death is striking because of how much he packed into those 49 years. He was an orphaned immigrant teenager who became George Washington's indispensable aide during the Revolutionary War, the principal author of the Federalist Papers, the first secretary of the treasury, and the architect of the American financial system — all before most people today would be mid-career.

The duel that killed him was the culmination of a decades-long rivalry with Burr. They met at dawn on July 11, 1804, on the dueling grounds at Weehawken, New Jersey. Burr's shot struck Hamilton in the abdomen; Hamilton died the next afternoon, surrounded by family and friends. He was buried in Trinity Churchyard in Manhattan, where his grave remains a pilgrimage site.

Biography Snapshot

Alexander Hamilton was born January 11, 1755, on Nevis in the British West Indies, to Rachel Faucette and James Hamilton, who were not married. His father abandoned the family, his mother died when he was about 13, and he was left largely to fend for himself — working as a clerk for a trading company while devouring books.

A hurricane essay he wrote at 17 so impressed local merchants that they funded his education in America. He arrived in New York in 1772, attended King's College (now Columbia), and threw himself into the revolutionary cause. By 1777, at about 22, he was Washington's aide-de-camp, handling correspondence and strategy for the Continental Army.

After the war, Hamilton became the driving force behind the Constitution's ratification, writing 51 of the 85 Federalist Papers. As treasury secretary from 1789 to 1795, he created the national bank, established the federal government's credit, and laid the foundations of American capitalism. He founded the Federalist Party in 1789, America's first political party.

Wife Eliza and Eight Children

Hamilton married Elizabeth Schuyler — Eliza — on December 14, 1780, when he was 25 and she was 23. Eliza was the daughter of Philip Schuyler, a wealthy New York general and senator, and the marriage connected Hamilton to one of America's most powerful families. It was, by most accounts, a genuine love match.

The couple had eight children: Philip (born 1782), Angelica (1784), Alexander Jr. (1786), James Alexander (1788), John Church (1792), William Stephen (1797), Eliza (1799), and Philip — named for his late brother — born in 1802. Raising eight children while Hamilton built a nation was Eliza's enormous, largely unsung achievement.

The family's great tragedy came in 1801, when 19-year-old Philip Hamilton was killed in a duel — at the same Weehawken grounds where his father would die three years later. Philip had been defending his father's honor against a young lawyer's insults. The loss devastated Hamilton and Eliza; Hamilton reportedly never fully recovered. Eliza, who was pregnant at the time, gave birth to their last child months later and named him Philip.

Eliza Hamilton's Long Life

Eliza Schuyler Hamilton outlived her husband by exactly 50 years, dying in 1854 at the age of 97. Those five decades were devoted to preserving Alexander's legacy: she organized his papers, lobbied for the publication of his writings, and defended his reputation against political enemies.

She also became a significant philanthropist in her own right, co-founding the first private orphanage in New York City — the institution that became Graham Windham — and raising funds for the Washington Monument. Her longevity meant she saw the nation her husband helped create grow from a fragile republic into a continental power.

The Broadway musical Hamilton brought Eliza's story to a new generation, with the closing number Who Lives, Who Dies, Who Tells Your Story centered on her half-century of remembrance. She died in Washington, D.C., and is buried beside Alexander in Trinity Churchyard.

The Duel With Aaron Burr

The Hamilton-Burr rivalry had been building for 15 years: political opposition, personal insults, and Burr's belief that Hamilton had repeatedly sabotaged his career. The breaking point came in 1804, when Hamilton allegedly made disparaging remarks about Burr at a dinner party. Burr demanded an apology; Hamilton refused to retract what he wouldn't confirm saying.

They met at Weehawken on the morning of July 11, 1804. What exactly happened in those seconds remains debated — Hamilton's shot went wide (some say deliberately, as he had told friends he would not fire at Burr), while Burr's shot found its mark. Hamilton was carried to a nearby house, where he lingered for about 31 hours before dying on July 12.

Burr was charged with murder in New York and New Jersey but never tried; the charges were eventually dropped. His political career was destroyed anyway. He finished his term as vice president as a pariah and is remembered primarily as the man who killed Hamilton.

Hamilton's Legacy

Hamilton's legacy is everywhere in modern America: the treasury he built, the financial system he designed, the Coast Guard he founded, and the $10 bill that bears his face. His vision of an energetic federal government and a commercial republic won the long argument against Jefferson's agrarian ideal.

For two centuries he was the Founding Father without a monument — no grand memorial like Washington or Jefferson. That changed culturally in 2015 with Lin-Manuel Miranda's Hamilton, which turned his life into a global phenomenon and made his story the most-told of any Founder among young Americans.

His grave at Trinity Church in lower Manhattan draws constant visitors. The epitaph notes his service; the crowds note the musical. Either way, the orphan from Nevis who died at 49 in a duel remains one of the most vivid figures in American history.

Hamilton's Age in Context

Dying at 49 in 1804 was not as unusual as it sounds today — life expectancy was far lower — but Hamilton's death was shocking because of who he was and how it happened: a former treasury secretary killed by the sitting vice president in a ritual that was already becoming an anachronism.

The birth-year dispute (1755 vs. 1757) matters to historians because Hamilton himself may have shaved two years off his age when applying to college — a small vanity that created a centuries-long footnote. Most scholars now accept 1755, making him 49 at death.

His children lived long lives by contrast: his son James Alexander Hamilton lived to 88, dying in 1878. Eliza's 97 years meant she personally bridged the Revolution and the Civil War era — a living link to the founding generation.

What makes Hamilton's story endure is the arc: from abandoned child to nation-builder to duel victim, all by 49. Few lives in history have contained so much in so few years.

The Reynolds Affair and Final Years

Hamilton's career was nearly destroyed by America's first major sex scandal. In 1791, he began an affair with Maria Reynolds, whose husband then blackmailed him. When political enemies accused Hamilton of financial corruption, he published the Reynolds Pamphlet in 1797 — a 95-page confession of adultery to prove he was guilty of cheating, not stealing. Eliza stood by him, but the humiliation was total.

After leaving the Treasury in 1795, Hamilton practiced law in New York, becoming one of the city's top attorneys. He remained politically active, feuding with John Adams, Aaron Burr, and Thomas Jefferson — his pen as sharp as ever. He founded the New-York Evening Post (now the New York Post) in 1801.

His final years were shadowed by son Philip's 1801 duel death and the escalating Burr rivalry. By 1804, the duel that killed him felt, to contemporaries, almost inevitable — the last act of a man who had always lived at full tilt.
