The Story Behind Thomas Jefferson's "The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants."

It was the winter of 1787, and I had just returned to Paris after a long, arduous journey through the French countryside. The air was sharp with frost, and the city’s streets buzzed with the scent of woodsmoke and revolution. I had been serving as the American Minister to France since 1785, watching closely as the ideas of liberty and republicanism began to stir across the Atlantic. In a letter to William Stephens Smith dated November 13, 1787, I wrote a line that would echo through the centuries: “The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.” It was not a call to violence, but a stark acknowledgment of the cost of freedom — a truth I had come to believe deeply after witnessing the birth of a nation and the fragility of its ideals.

A Letter Written in Paris

The letter was penned at my residence on the Rue de Berri, a modest but comfortable home where I often entertained diplomats, philosophers, and young Americans eager to learn from my experience. I was in the midst of translating Montesquieu and corresponding with James Madison about the new Constitution being drafted in Philadelphia. The American Revolution had ended just a few years earlier, and the young republic was still finding its footing. The Federalists and Anti-Federalists were locked in a heated debate over the balance of power between the central government and the states. In this climate of uncertainty, I felt compelled to remind those I trusted of the eternal vigilance required to preserve liberty.

A Metaphor Rooted in Experience

The metaphor of the “tree of liberty” was not original to me — it had been used in various forms by Enlightenment thinkers and revolutionaries alike — but it resonated with my own view of governance. I had seen how easily power could be abused, how even well-intentioned leaders could slip into tyranny if unchecked. The American Revolution had proven that people were willing to risk everything for self-rule, and I believed that spirit must never be extinguished. To me, the shedding of blood — whether in protest, rebellion, or defense — was a grim but necessary reminder that liberty was not a gift to be taken for granted. It was a living thing, requiring nourishment and sacrifice.

The Reaction at Home and Abroad

At the time, the letter remained private, shared only among a small circle of correspondents. Smith himself, a soldier and diplomat, understood the gravity of the words but did not publish them. Years later, as tensions rose during the Quasi-War with France and the bitter political battles of the early 1800s, the quote found new life. It was invoked by both friends and foes, sometimes twisted to fit causes I had never intended. Some saw it as a warning against complacency; others, a call to arms. In France, revolutionaries embraced the phrase as a rallying cry. In America, it was quoted in newspapers and pamphlets by those who feared growing federal overreach. I never publicly expanded on the quote, but I stood by its meaning: liberty must be defended, even when the cost is high.

The Legacy of a Line

After my death in 1826, the quote continued to evolve in the public imagination. It appeared in biographies, political speeches, and eventually, in classrooms and history books. Some admired it as a testament to the enduring spirit of revolution; others condemned it as dangerously incendiary. It was cited during the Civil War, the labor movements of the 19th century, and even in the 20th century by those fighting for civil rights and independence abroad. I never could have predicted how deeply the phrase would embed itself in the American consciousness. It was a line born of reflection and caution, yet it often found itself wielded with passion and urgency — a reminder that words, once spoken, take on lives of their own.
