The road they walked

Thomas Jefferson was born in 1743 at Shadwell, a Virginia plantation, into the world of the tidewater gentry — a class built on tobacco, land, and the labor of enslaved people, several hundred of whom he would come to own over his lifetime, inheriting his first dozen at age fourteen. He was formidably educated, first at William & Mary, then reading law under George Wythe, and he emerged from that training a young man fluent in classical philosophy, architecture, science, and the new political language of natural rights. By his early thirties he had a seat in the Virginia House of Burgesses and a reputation as a gifted, if famously reluctant, public speaker — someone who did his persuading with a pen rather than his voice.

That pen made him. In June 1776, at thirty-three, he was handed the task of drafting a declaration for the Continental Congress and produced a document whose opening lines would outlive every argument about its author — a claim of universal equality written by a man who held people in bondage his entire adult life, a contradiction that shadowed the nation he helped found as much as it shadowed him personally. The decades after brought him through the office of Virginia's wartime governor (a term ending in controversy when the British nearly captured him), minister to France during the run-up to its revolution, the nation's first Secretary of State under Washington, and a bitterly contested vice presidency and presidency shaped by the new party rivalries he helped invent. His own election in 1800, wresting power from the Federalists without violence, he called a second American revolution — a peaceful transfer that set a precedent the young republic badly needed.

As president he nearly doubled the country's size with the Louisiana Purchase in 1803, sent Lewis and Clark west to survey what he'd bought, and fought an inconclusive war against Barbary pirates, while a later trade embargo meant to keep America out of European wars badly damaged the economy and his popularity. Retirement did not slow him: he spent his final decades at Monticello, the plantation home he designed and redesigned for forty years, founded and personally planned the University of Virginia down to its curriculum and rotunda, and carried on a famous late-life correspondence with his old rival turned friend John Adams. Modern historians, backed by DNA and documentary evidence, now largely accept that Jefferson fathered children with Sally Hemings, an enslaved woman at Monticello — a fact once dismissed by his defenders and now central to how his legacy is understood.

How their story ended

Jefferson died at Monticello on July 4, 1826, deeply in debt and only hours before John Adams died in Massachusetts — the two having outlived their rivalry to become correspondents and friends, both gone on the fiftieth anniversary of the Declaration they'd helped write. His final months were marked by failing health from a combination of chronic ailments rather than any single dramatic cause, and his estate, insolvent, was settled after his death by selling his land, possessions, and the people he had enslaved.

In their words

Never put off till tomorrow what you can do today.

Letter to Thomas Jefferson Smith, February 21, 1825

The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Letter to William Stephens Smith, November 13, 1787

I have sworn upon the altar of God eternal hostility against every form of tyranny over the mind of man.
