Critics of President Donald Trump’s administration plan to gather in numerous cities on Saturday, coinciding with a military parade in Washington celebrating the Army’s 250th anniversary — an event that aligns with Trump’s birthday.

The “No Kings” demonstrations are organized as a rebuttal to what they describe as Trump’s attempt to self-aggrandize on his 79th birthday and Flag Day.

While the Army birthday celebration was already on the calendar, Trump announced earlier this year that he wanted to amplify the event with a display featuring 60-ton M1 Abrams tanks and Paladin self-propelled howitzers navigating the city streets, a show of patriotic strength he has long desired.

Why is it called No Kings?

The “No Kings” theme was orchestrated by the 50501 Movement, a national movement made up of everyday Americans who stand for democracy and against what they call the authoritarian actions of the Trump administration. The name 50501 stands for 50 states, 50 protests, one movement.

Protests earlier this year have denounced Trump and billionaire adviser Elon Musk, the now former leader of Trump’s Department of Government Efficiency, a government organization designed to slash federal spending. Protesters have called for Trump to be “dethroned” as they compare his actions to that of a king and not a democratically elected president.

“They’ve defied our courts, deported Americans, disappeared people off the streets, attacked our civil rights, and slashed our services,” the group says on its website, referring to the Trump administration and its policies. “They’ve done this all while continuing to serve and enrich their billionaire allies.”

Why are they protesting on Saturday?

The No Kings Day of Defiance has been organized to reject authoritarianism, billionaire-first politics and the militarization of the country’s democracy, according to a press release from No Kings.

It is happening to counter the Army’s 250th anniversary celebration — which Trump has ratcheted up to include an expensive, lavish military parade. The event, will feature hundreds of military vehicles and aircraft and thousands of soldiers. It also happens to be his 79th birthday and Flag Day.

“The flag doesn’t belong to President Trump. It belongs to us,” the No Kings website says. “On June 14th, we’re showing up everywhere he isn’t — to say no thrones, no crowns, no kings.”

Where are the protests?

Protests in nearly 2,000 locations are scheduled around the country, from city blocks to small towns, from courthouse steps to community parks, according to the No Kings website.

No protests are scheduled to take place in Washington, D.C., however, where the parade will be held. The group says it will “make action everywhere else the story of America that day.”

No Kings plans instead to hold a major flagship march and rally in Philadelphia to draw a clear contrast between its people-powered movement and what they describe as the “costly, wasteful, and un-American birthday parade” in Washington, according to the No Kings website.

What is planned at the No Kings protests?

People of all ages are expected to come together in the protest locations for speeches, marching, carrying signs and waving American flags, organizers said in a call Wednesday.

On the group’s website it says a core principle behind all No Kings events is a commitment to nonviolent action, and participants are expected to seek to de-escalate any potential confrontation with those who disagree with them.

Weapons of any kind should not be brought to events, according to the website.

How many people are expected to participate?

The No Kings Day of Defiance is expected to be the largest single-day mobilization since Trump returned to office, organizers said. Organizers said they are preparing for millions of people to take to the streets across all 50 states and commonwealths.
