You've probably seen the yellow shirts. Maybe you’ve scrolled past a video of thousands of people chanting "Not My King" or seen the posters of Donald Trump superimposed over George III. It’s a lot. Honestly, if you’re confused about what is the no king protest, you aren't alone. It is a messy, sprawling movement that means one thing in London and something entirely different in Washington D.C.
People are angry. That’s the baseline. But the anger is directed at two very different "monarchs" depending on which side of the Atlantic you're standing on. In the U.S., it's a massive pushback against what critics call the "imperial presidency" of Donald Trump’s second term. In the UK, it’s a literal fight to get rid of the House of Windsor.
The American Version: Fighting the "New King"
In the United States, the no king protest is basically a survival mechanism for the left. It isn't about King Charles. It’s about the idea that the President of the United States shouldn't act like a monarch. This movement exploded in 2025, specifically on June 14—which, interestingly enough, is both Flag Day and Donald Trump’s birthday.
Organizers like Indivisible and the ACLU didn't pick the name by accident. They are leaning hard into the imagery of the American Revolution. You’ll see people dressed as "bluecoats" (the Continental Army) facing off against "redcoats" who represent the administration. It’s high-stakes political theater. The goal? To remind the government that the U.S. was founded specifically to not have a king.
The scale of these things is actually kind of wild.
- June 2025: Around 4 to 6 million people hit the streets in 2,100 cities.
- October 18, 2025 (No Kings 2.0): The numbers stayed huge, with nearly 7 million people participating across 2,700 locations.
- The Vibe: It’s a mix of a protest and a history lesson. They cite the Declaration of Independence constantly, particularly the parts about a "long train of abuses."
Honestly, it’s not just about slogans. These protesters are reacting to very specific policies. We’re talking about mass deportations, the use of the military in American cities, and the withholding of FEMA funds from "blue" states. For these people, the term "king" isn't a metaphor; it’s a warning.

The UK Version: "Not My King" and the Republic
Now, if you jump over to London, the no king protest is literal. No metaphors here. They actually want the King gone. The group Republic is the main driver behind this. They’ve been at it for decades, but the death of Queen Elizabeth II and the coronation of King Charles III gave them a massive boost.
You’ve likely seen their "Not My King" yellow placards. They are bright, they are ugly, and they are everywhere the King goes.
The logic is pretty straightforward. Why are we paying millions for a coronation when people can't pay their heating bills? Why does the Duchy of Cornwall pay Prince William £23 million a year in "private" income while it’s essentially public land? It’s a fiscal argument wrapped in a democratic one.
Republic is planning their next big move for Republic Day on May 9, 2026. They are literally marching on Buckingham Palace. They even have a fifteen-foot mechanical mascot named "Chuck the Rex." It’s a bit absurd, but it gets the cameras moving.
Why the Two Movements are Merging (Sorta)
Even though the targets are different, the tactics are starting to bleed into each other. Social media has created this weird feedback loop. Americans are using the "Not My King" slogans they saw in London, and British activists are adopting the "Bluecoat" rhetoric of defending democracy against "tyrants."

Interestingly, the no king protest in the U.S. is looking toward July 4, 2026—the 250th anniversary of the country. Expect that to be the biggest one yet. They want to re-enact the Battles of Lexington and Concord. It's basically a massive, country-wide LARP (Live Action Role Play) with the highest possible political stakes.
What Most People Miss
The biggest misconception is that these are just "angry riots." Most of the data, like the surveys conducted by the Brookings Institution, show that these crowds are actually highly educated and overwhelmingly peaceful.
But there’s a dark side.
Support for "political violence" as a tool to save the country has been creeping up. Among left-leaning participants in the U.S., it jumped from 17% in 2024 to 26% in late 2025. People feel like the system is broken beyond repair. When people feel like they have no voice in a "democracy," they start looking for other ways to be heard.
Key Differences at a Glance
In the US, the protest is against a President acting like a King, led by groups like Indivisible and MoveOn. They use American Revolution imagery and the color blue. In the UK, the protest is against the literal Monarchy, led by Republic. They use the "Not My King" slogan and the color yellow.
The US movement is about the 2024 election aftermath and the "imperial presidency." The UK movement is about the cost of living and the inherent unfairness of hereditary power.

Actionable Insights for the Current Climate
If you’re planning to attend or just want to understand the no king protest, keep a few things in mind.
First, the legal landscape is changing fast. In the UK, the Crime and Policing Bill 2025 has made it much easier for police to arrest you just for being "disruptive." We’ve seen people arrested just for holding a sign.
Second, if you're in the U.S., the 250th-anniversary events in July 2026 are going to be the focal point. If you want to get involved, local chapters of Indivisible or the ACLU are the primary hubs for coordination.
Finally, don't ignore the digital side. Most of these rallies are organized on TikTok and Reddit using the #NoKingsDay hashtag. Following those threads is the only way to get real-time updates on locations, especially when the authorities start cracking down on "unauthorized" gatherings.
The "No King" sentiment isn't a passing trend. It’s a fundamental shift in how people view authority. Whether it's a president or a prince, the message is the same: the era of unquestioned power is over.
Keep an eye on the Commonwealth Day Protest on March 9, 2026, at Westminster Abbey. It’ll be the first major litmus test of how the UK government intends to handle dissent as the anti-monarchy movement grows. In the U.S., the focus remains on the "No Kings" demonstrations planned for Independence Day, which are shaping up to be a defining moment in the second Trump term.
