You've seen it on bumper stickers. It shows up in gritty action movies and on the backs of t-shirts at political rallies. Someone usually quotes it when they’re feeling particularly frustrated with the government. "The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants." It sounds like a battle cry. It’s heavy, violent, and deeply American.
But honestly, most people have no clue about the context.
When Thomas Jefferson sat down to write those words in 1787, he wasn't standing on a battlefield. He wasn't even in America. He was in Paris, living a relatively posh life as a diplomat, sipping French wine while his friends back home were freaking out about a small-scale rebellion in Massachusetts. To understand why Jefferson thought a little bloodshed was "natural," you have to look at the mess that was the post-Revolutionary United States.
Shays’ Rebellion and the Letter to William Smith
History is messy. After the British left, the new United States was basically a collection of thirteen grumpy roommates who couldn't agree on how to pay the rent. Massachusetts was hit hard. Farmers, many of whom were Revolutionary War veterans, were losing their land because they couldn't pay their debts in hard currency.
Enter Daniel Shays.
In 1786, Shays led a group of armed farmers to shut down courts and attempt to seize a federal armory. This scared the absolute daylights out of the "Founding Fathers." George Washington was horrified. James Madison was losing sleep. They thought the country was dissolving into "anarchy."
But Jefferson? He was chill.

On November 13, 1787, he wrote a letter to William Stephens Smith, the son-in-law of John Adams. Jefferson thought the panic over Shays' Rebellion was ridiculous. He basically told Smith that people shouldn't get so worked up over one little riot. He wrote: "God forbid we should ever be 20 years without such a rebellion." He figured that if the people don't protest—even violently—it means they’ve become lethargic, and lethargy is the death of freedom.
That’s where the tree of liberty and the blood of tyrants line comes from. It wasn’t a call for perpetual civil war. It was an observation that a government that doesn't fear its people is a government that will eventually become a tyranny.
Jefferson's Wildly Different Vibe
It’s kinda funny how different Jefferson was from the other Founders. While Madison was obsessing over "checks and balances" and the "tyranny of the majority," Jefferson was over in France thinking, "Yeah, a little uprising every now and then keeps the politicians honest."
He viewed political rebellion like a thunderstorm.
Sure, lightning might strike a tree, but the rain clears the air. He famously said in the same era that "a little rebellion now and then is a good thing." He believed that no government could be perfect and that the people had a right to be "uninformed" or "mistaken" sometimes. To him, it was better for the people to be rowdy and wrong than quiet and submissive.
Modern historians, like those at Monticello, point out that Jefferson’s "blood of tyrants" quote is often used today to justify modern militia movements or revolutionary fantasies. However, in 1787, Jefferson was defending a group of farmers who felt they were being taxed into poverty without a voice. He was prioritizing the spirit of resistance over the stability of the state.

Washington disagreed. Hard.
Washington wanted order. He wanted a central government that could pay its bills and stop local uprisings. This tension between Jefferson’s "liberty first" and Washington’s "order first" is basically the DNA of American politics. We’re still arguing about it today.
Why the Tree of Liberty Quote Still Matters
Why does this specific sentence stick? Because it hits a nerve. It suggests that freedom isn't a "set it and forget it" system. It’s an organism. Organisms need nutrients. In Jefferson’s metaphorical world, the "manure" (yes, he actually used that word in the letter) that makes the tree grow is the willingness of people to fight back.
- The Warning to Leaders: Jefferson believed that if leaders aren't reminded that the people have teeth, they will stop caring about the people's rights.
- The Cost of Apathy: He genuinely feared a public that just sat back and let things happen. To him, a peaceful but oppressed society was worse than a chaotic but free one.
- The "Natural" State of Politics: He saw these rebellions as a natural consequence of misinformation or genuine grievance, not as a reason to scrap the whole system.
It’s important to realize Jefferson wasn't a pacifist. He was a radical. Even though he didn't pick up a musket during Shays' Rebellion, he provided the intellectual cover for those who did. He knew that liberty is fragile.
The Misunderstandings
People often use this quote to imply that we need a violent revolution every few years. That’s probably a stretch. Jefferson was talking about a specific event where very few people actually died. He was being hyperbolic to make a point to his friend Smith. He was saying, "Look, we’ve had one rebellion in eleven years. That’s nothing! Most countries have it way worse."
He was trying to calm the nerves of the elites who wanted to crack down on civil liberties in the name of "security."

Actionable Insights for the Modern Reader
Understanding the tree of liberty and the blood of tyrants isn't just a history lesson. It’s a framework for how you view the relationship between a citizen and the state. If you want to apply Jefferson’s logic without starting a literal revolution, here’s how to look at it:
- Question the "Stability" Narrative. When politicians tell you that protest is "dangerous" or "bad for the country," remember that Jefferson thought a bit of chaos was a sign of health. High-friction democracy is often more honest than a perfectly quiet one.
- Read the Full Letter. Don't just take the quote from a meme. Search for "Jefferson letter to William Stephens Smith 1787." Read the whole thing. You’ll see he was actually talking about the importance of education and the free flow of information.
- Differentiate Between Rebellion and Insurrection. Jefferson valued the motive behind the resistance. He believed the people should be informed. If a rebellion is based on lies, the remedy isn't just force—it's "instruction."
- Acknowledge the Complexity. Jefferson was a man of contradictions. He wrote about the "tree of liberty" while owning hundreds of enslaved people who had no liberty at all. Understanding the quote means acknowledging the flawed human who wrote it.
The "tree of liberty" isn't a call to arms for every minor grievance. It’s a philosophical reminder that the default state of government is to grow and consolidate power. Resistance, in whatever form it takes—voting, protesting, speaking out, or legal challenges—is the only thing that keeps that growth in check. Jefferson’s point was simple: freedom requires a cost. Sometimes that cost is just the discomfort of a rowdy, loud, and messy public square.
To really get why this matters, look at the transition from the Articles of Confederation to the U.S. Constitution. The "blood of tyrants" quote was written right as the Founders were debating how much power the federal government should actually have. Jefferson was the voice in the room (or the voice across the Atlantic) saying, "Don't give them too much."
Keep your eyes on the history. It’s much more interesting than the bumper stickers.
